Description

There is the sprinkler of brake assemblies

Technical field

The present invention relates to irrigation sprinkler, and relate more specifically to rotary sprinkler.

Background technology

Having the sprinkler configuration of the number of different types for irrigating object, comprising rocker-arm or pulsed driven sprinkler, motro drivien sprinkler and rotating reaction driven formula sprinkler.Be included in this rotation reaction driven formula sprinkler is a kind of sprinkler being known as whirligig or the rotary sprinkler usually used in the irrigation of crops and fruit tree.Usually, this rotary-type sprinkler comprises fixing supporting structure or framework and rotatable deflector, wherein, this supporting structure or framework are suitable for connecting with the supply source of pressure (hydraulic) water, and this deflector is supported by this framework and rotates for around roughly vertical axis.Most of rotary-type sprinkler adopts the nozzle or fixed nozzle that rotate reaction driven, and current are vertically ejected on the deflector of rotation by this fixed nozzle.Current are rebooted into approximate horizontal spraying by this deflector, and the reaction force that this deflector is produced by the impingement flow of origin self-retaining nozzle rotates.

The defect that rotary-type sprinkler faces is: due to the very high speed of rotation of whirligig, and the distance that therefore water is dished out from sprinkler may reduce widely.This generates controlling or regulating the rotary speed of deflector and thus regulate current to scan the demand of the speed of ground region around.In order to the deflector rotary speed making throwing relatively slow apart from maximum demand, and therefore, have developed various brake apparatus to realize this object.

In one approach, Viscous braking device is used to control the rotation of deflector.This Viscous braking device utilizes by making brake rotors in viscous fluid inward turning then the towing produced.Although be applicable for some sprinklers, this Viscous braking device may not provide constant rotary speed when environment temperature or supply pressure change.

Another defect that rotary-type sprinkler faces is: sprinkler has framework support, and framework support interferes current after current are rebooted by deflector.Carried out many trials to minimize to make this interference, these attempt comprising the support utilizing and have varying cross-section shape.But even if by these methods, when deflector completes rotation, current still impact support.This creates and reduces but still the impact existed in the spray pattern of sprinkler.

The another defect of some existing rotary-type sprinklers is the maintenance property of sprinkler.Rotary-type sprinkler has the fault of two kinds of typical types usually, and sprinkler removes to place under repair from water supply source by these two kinds of failure requirements.The fault of the first type occurs when nozzle becomes and blocked by the chip from water supply source.For some sprinklers, nozzle installs from the downside of sprinkler, and making needs to remove sprinkler to remove and washer jet from water supply source.The fault of the second type occurs when the deflector of sprinkler stops the rotation or rotate all to pieces.In this case, brakes had lost efficacy and whole sprinkler will be replaced.

Some existing sprinklers utilize viscous braking to control the rotary speed of the deflector of sprinkler.A problem of this method is that the viscosity of working fluid and temperature change on the contrary.As a result, deflector raises along with temperature and rotates faster, and reduces along with temperature and rotate slower.This change of rotary speed aspect may affect the area covered by sprinkler negatively, or may make deflector during cryogenic conditions with stall time coupled low voltage operated.

In order to brake apparatus 24 is connected to framework 14, the terminal part 77 (see Fig. 5) of lid 54 proceeds in frame openings 30, wherein, cover 54 and be located so that the lug 25 dangled is not crossed coupling member 122 but is laterally positioned to coupling member 122 rotatably around axis 52.When the protuberance 74 of brake apparatus 24 and the opening 126 of coupling member 122 are axially on time, lid 54 and lug 72 thereof turn to latched position along direction 130, and this makes protuberance 74 slide into (see Fig. 1 and Figure 19) in opening 126.Retainer 76 carries out camming movement on coupling member 122---this makes lug 72 outwards be biased---and coupling recess 124.This bias action creates and remains in recess 124 retainer 76 to prevent the reaction force of accidental removal.Opening 126 has wall 126A and 126B, wall 126A and 126B engagement tabs 74 and limit the lengthwise movement of brake apparatus 24 along axis 52.In addition, brake apparatus retainer 76 has the convex external surface 76A (see Fig. 8 A and Figure 19) engaged with the complementary female surface 124A of frame recesses 124.Joint between retainer 76 and recess 124 limits the rotary motion that lug 72 leaves latched position.Therefore, the lid 54 being limited rotation displacement or vertical shift is releasably fastened to framework 14.In order to make brake apparatus 24 be disengaged with framework 14, lid 54 is rotated along direction 132, this makes braking parts 76 off normal from recess 124 and brake apparatus lug 72 is disengaged (see Fig. 1) with framework coupling member 122.

With reference to Fig. 5 and Figure 19, nozzle 20 is releasably attached to the bottom 18 of framework 14 by the interlocking portion of nozzle 20 and the interlocking portion of framework nozzle socket 21.In one form, the interlocking portion of nozzle 20 and the interlocking portion of nozzle socket 21 are similar to the releasable connection portion of brake apparatus 24 and framework upper 14.In addition, nozzle 20 is connected to nozzle socket 21 in the mode being similar to the process be arranged on framework upper 16 by brake apparatus 24.Nozzle 20 has the collar 140, and this collar 140 has pendency lug 142, and this pendency lug 142 is configured to engage the coupling member 144 (see Fig. 2 and Figure 19) be arranged on the outer wall 146 of nozzle socket 21.

As shown in Figure 2, deflector 22 be positioned at nozzle 20 top and near nozzle 20.Brake apparatus 24 can be disengaged with framework 14 (and deflector 22 moves up) thinks that removing nozzle 20 provides gap.To understand, brake apparatus 24 and nozzle 20 be can from top maintenance and all can when not needing to be removed sprinkler 10 is removed from fluid feed sources.

Sprinkler 10 can be configured to receive the different spray nozzles 20 with various flow rates etc. to apply for required sprinkler.The collar 140 and pendency lug 142 are similar to allow different nozzles 20 releasably to engage with nozzle socket coupling member 144 between different nozzles 20.

As shown in Figure 7, brake assemblies 24 comprises the clamping device of braking element 56 and such as brake disc 58 and brake area 67 and so on, this gripping apparatus grips braking element 56 and slow down guiding transposition 22 rotation.Brake disc 58 is positioned at the below of braking element 56 and is attached to the axle 60 carrying deflector 22, and brake disc 58 is rotated along with the rotation of deflector 22.Brake area 67 to be arranged on the downside of lid 24 (on the side relative with brake disc 58 of braking element 56) and to be fixing relative to the braking element 56 rotated.As discussed in more detail below, impact the fluid of deflector 22 deflector 22 and brake disc 58 are rotated, brake disc 58 is moved up and between brake disc 58 and brake area 67 compression brake component 56.This generates the frictional resistance that deflector 22 is rotated.

Braking element 56 can be taper and be limited (see Fig. 7, Figure 10, Figure 11) by lower friction surface 78 and upper friction surface 80.Surface 78 and 80 all has the groove 82 extended radially outwardly from central opening 84 (this central opening 84 be received through its axle 60), and wherein, as shown in figs. 9 and 10, each groove 82 all has inner fovea part 86 and outer recess 88.Groove 82 can play and be stuck in braking element 56, dust between brake disc 58 and brake area 67 and chip and radially outward guide becoming the function leaving axle 60.This operation suppresses dust and chip to cling the rotation of brake disc 58 (and being connected to the deflector 22 of this brake disc 58).In one approach, the lubricant of such as lubricating grease and so on can be used in brake assemblies 24 to increase the rotatable easness of deflector 22.In the method, groove 82 is in order to catch the overlubricate fat of the frictional qualities that may affect contact surface.

With reference to Figure 10 A, show another braking element 56A.Braking element 56A is roughly similar to braking element 56 and comprises the upper friction surface 80A and lower friction surface 78A it with groove 82A.But braking element 56A is smooth, but not there is the conical by its shape of braking element 56.

With reference to Fig. 5, Fig. 7, Figure 12 and Figure 13, brake disc 58 has upper plate portion 90 and socket 92, and wherein, this upper plate portion 90 has the friction surface 91 for engagement brake component 56, and this socket 92 longitudinally down extends from plate portion 90.Socket 92 has the opening 94 of hexagonal shape and the pass through openings 96 for being received through its axle 60.With reference to Fig. 5 and Fig. 7, axle 60 has the spline 104 of top 98, bottom 100, hexagonal ferrule 102 and bottom 100.Top 98 is positioned at the opening 84 of braking element 56 and the opening 96 of brake disc 58.The hexagonal configuration that socket 92 has a coupling is with the hexagonal ferrule 102 of engages axle and the rotary motion limited between socket 92 and the collar 102.The bottom 92A of the upper surface 102A socket object 92 of the collar 102, makes the upwards lengthwise movement of axle 60 the upper surface 102A of axle sleeve ring 102 to be engaged with 92A bottom socket and makes brake disc 58 upward displacement.

Axle 60 has the bottom 100 being sized to and being engaged in the recess 105 of deflector 22.Axle bottom 100 has spline 104, the cooperation spline in spline 104 coupling recess 105.Being bonded with each other of described spline keeps the deflector 22 that is arranged on axle bottom 100 and limits the relative rotary motion of deflector 22 around axle bottom 100.In another approach, recess 105 has smooth hole, and axle bottom 100 is press-fitted in recess 105.

Referring now to Fig. 7, Figure 14 and Figure 15, braking base portion 62 has elastic lug 112, and braking base portion 62 is releasably connected in brake cover 54 by elastic lug 112.Elastic lug 112 is erect from dish 110 and is comprised protuberance 114, and protuberance 114 bears against the inner surface 54A (see Fig. 8) of brake cover 54 when braking base portion 62 and to be inserted in lid 54 and lug 112 proceeding in brake cover recess 66 and lug 112 is radially-inwardly bent.Protuberance 114 snaps fit onto in the groove 68 of brake cover 54 to be fastened in brake cover 54 by braking base portion 62.

In another approach, braking base portion 62 can ultra-sonic welded or adhere to brake cover 54, instead of utilizes elastic lug 112 to be connected to brake cover 54.In another method, braking base portion 62 can utilize the structure may carrying out hardly dismantling for good and all to be connected to brake cover 54 when not damaging sprinkler 10.Such as, the protuberance 114 of elastic lug 112 can have following sharp-pointed profile: described sharp-pointed profile allows lug 112 to be snapped in brake cover 54 along direction of insertion, but needs protuberance 114 distortion in the opposite direction.

When braking base portion 62 and being installed in brake cover 54, braking base portion 62 is fastened to framework 14 during the operation of sprinkler 10.As shown in Fig. 7, Figure 14, Figure 15, braking base portion 62 has sleeve 108, and this sleeve 108 has the pass through openings 106 being sized to and receiving axle 60.Sleeve 108 allows the rotary motion of sleeve 108 in opening 106 and lengthwise movement.In addition, as shown in Figure 7, this sleeve has upper end 108A, the bottom of this upper end 108A engagement shaft collar 102 and downward lengthwise movement of restrictive axes 60 exceeds precalculated position.Sleeve upper end 108A plays the function of the lower stopper section for axle 60.

With reference to Figure 16 to Figure 18, the passage 48 of deflector 22 can have unlimited configuration, and this configuration opened wide has the opening 48A extended along passage 48 side.Passage 48 has wall 118 in the relative both sides of passage 48, wherein, a wall 118A in described wall has the axial inclined surface 116 in order to guide the fluid stream through deflector 22, and another wall 118B has the inclined-plane 120 be tangentially guided out from the outlet 50 of deflector 22 by this fluid stream.Pass passage 48 due to water and flow against inclined-plane 120, because which form the reaction force tangent with the rotation 52 of deflector 22, thus the axle 60 of deflector 22 and attachment is rotated (see Fig. 1 and Figure 21) along direction 150 relative to framework 14.

Passage 48 also has curved surface 122, and the axial fluid flow from nozzle 20 is rebooted into the fluid stream of radially outward advancing from deflector 20 by this curved surface 122.Inclined surface 116 guides fluid stream when fluid is advanced along curved surface 122 towards wall 118B.Inclined surface 116 and curved surface 122 operate into and guide fluid towards inclined-plane 120 and make fluid leave the outlet 50 of deflector with the predetermined angular enough making deflector 22 and rotate.The shape that the described surface of passage 48---comprises surface 116,120 and 122---can revise to provide required homogeneous (uniform) fluid stream when fluid stream leaves deflector 22 as required.To understand, passage 48 can have other features of an one, two, three or more flat surfaces and such as one or more groove, to realize from the even fluid distribution needed for deflector 22.

With reference to Figure 37 to Figure 39, show deflector 500, this deflector 500 has the groove 506 that internal channel 502, end difference 504 and the inner surface along passage 502 extend.Groove 506 near upper end (when observing in Figure 37) guides the upper part of fluid stream to feed water 508 to provide far field, and the end difference 504 near bottom guides the low portion of fluid stream to feed water 510 to provide near field.Deflector 500 can use together with sprinkler 10, and deflector 500 is shown as generally and is in operation in Figure 39.By the upper part of fluid stream is guided farther, the low portion of the downward propelling fluid stream of upper part of deflector 500 limit fluid stream.This plays the throwing distance increasing sprinkler 520 and the function of spraying uniformity.

When fluid advances to deflector 22 from nozzle 20, fluid impact curved surface 122 and make deflector 22 by short stroke and be connected to axle 60 upward displacement of this deflector 22.The moving upward of axle 60 makes the upper friction surface 91 (see Fig. 5) of brake disc 58 be shifted into engage with the lower friction surface 78 of braking element 56.Short stroke and axial upward displacement that braking element 56 also engages with the brake area 67 covering 54 by being enough to make the upper friction surface 80 (see Fig. 7) of braking element 56 to be moved into.By this layout, braking element 56 be axially interposed in rotatably drive between brake disc 58 and irrotational brake area 67.Braking element 56 is frictionally resisted and the brake disc 58 and be connected to the rotary speed of deflector 22 of brake disc 58 of slowing down.

Fluid flow through nozzle 20 is larger, and the impulsive force of fluid to the curved surface 122 of deflector 22 is larger.This impulsive force is transformed into the larger upward force on the axle 60 and brake disc 58 that are applied to deflector 22 and are connected to deflector 22.As shown in Figure 7, along with fluid flow increases, this upward force makes braking element 56 little by little flatten and thus the major part 160 of the friction surface 80 of braking element is engaged with lid brake area 67.In addition, the major part 162 engagement brake dish 58 of the lower friction surface 78 also causing braking element that flattens of braking element 56.Therefore, along with the fluid flow of the increase from nozzle 20, be not that deflector 22 rotates faster, but brake apparatus 24 is applied with the brake force of increase to resist the reaction force of the increase from the fluid flow increased on deflector inclined-plane 120.

Smooth braking element 56A provides the increase similar with the impulsive force of fluid to the increase of the curved surface 122 of deflector 22 in brake force.More specifically, being frictionally engaged along with the increase of the fluid flow clashing into curved surface 122 (see Fig. 7) and increasing in braking between friction surface 80A, brake area 67 and braking element 58.This increase Producing reason is that frictional force is the function of the power applied in the direction of friction surface 67 along normal direction, and wherein, this normal force produced by the impact of fluid to the curved surface 122 of deflector 22 in this case.

With reference to Figure 21, sprinkler 10 has the additional features of the improved efficiency making sprinkler 10.In one form, sprinkler 10 has support 29, and support 29 has the cross section of the minimized air foil shape of impact making to be produced in the spray pattern of sprinkler 10 by support 29.More specifically, support 29 has leading section 170, the pars intermedia 172 of expansion and the rearward end 174 of convergent.Leading section 170 and rearward end 174 make the fluid stream 169 from deflector 22 little by little shift around support 29 and fluid stream 169 is recombined near rearward end 174.So, fluid stream 169 when substantially not supported portion 29 existence interrupt continue radially outward from support 29, compared with the sprinkler of routine, this reduce the impact of support 29.

Support 29 has cross section center line 180, and this cross section center line 180 is directed with angle 182 relative to the radius 184 of sprinkler.As shown in Figure 21, because fluid 169 impacts inclined-plane 120, therefore fluid 169 tangentially outwards marches to deflector exit opening 50 from deflector 22.Support center line 180 is directed in the mode of this tangential direction being roughly parallel to fluid and advancing, and this makes the fluid 169 of outwards advancing from deflector exit opening 50 head on contact leading section 170.This makes support cross section reboot fluid stream 169 around support 29 and recombine the ability maximization of fluid stream 169 when fluid stream 169 arrives rearward end 174.

The parts of sprinkler 10 are selected to generally provides enough intensity and durability to apply for specific sprinkler.Such as, brake axle 60 can be made up of stainless steel, and braking element 56 can be made up of elastomeric material, and the remaining part of sprinkler 10 can be made of plastics.

With reference to Figure 22 and Figure 23, show the sprinkler 200 being similar to sprinkler 10.But sprinkler 200 has the removable nozzle 20 of the nozzle 210 instead of sprinkler 10 formed with the framework 212 of sprinkler 200.Compared with sprinkler 10, in some applications, such as when not needing removable nozzle 20, sprinkler 200 can by cost lower manufacture and be desirable.

With reference to Figure 24 to Figure 29, show another sprinkler 300.Sprinkler 300 is similar to sprinkler 10 in many aspects, thus focuses on the difference between sprinkler 300 and sprinkler 100.A difference is that sprinkler 300 comprises body 302, this body 302 has base portion 304, support 308 and arm 312, wherein, this base portion 304 is rotatably arranged on nozzle 306, this support 308 is connected with rotary components 310, and base portion 304 is connected to support 308 by arm 312.Therefore, body 302 and rotary components 310 can rotate relative to nozzle 306 during use, and the framework 14 of sprinkler 10 and rotary components 15 are roughly fixed during use.Because body 302 can rotate about nozzle 306, the fluid stream therefore carrying out the deflector 320 of rotating component 310 impacts arm 312 and makes body 302 incrementally rotate short distance about nozzle 306.When deflector 320 is advanced by arm 312, this rotation increased progressively of body 302 all makes arm 312 move to different positions, and this makes the injection impact produced by arm 312 move continuously.By this way, sprinkler 300 has continual spray pattern within a period of time.

More specifically, body base 304 comprises the collar 330 with opening 332, this opening 332 be sized to be fitted in retaining member, such as nut 336 neck 334 on.At assembly process, the collar 330 slides on neck 334 and neck 334 is threaded on the setting outer wall 340 of nozzle 306.Nut 336 has flange part 342 and sleeve 344, and the collar 330 is captured on nozzle 306 by this flange part 342 and sleeve 344 between flange 342 and the support 350 of nozzle 306.In addition, nut 336 has wing 354, and wing 354 can be grasped and may be used for nut 336 to be tightened on nozzle 306.

The collar 330 has internal tooth 351, and internal tooth 351 has the groove 353 between internal tooth 351, and the neck 334 of nut 336 has smooth outer surface 355.When body 302 rotates relative to nut 336 and nozzle 306, tooth 351 slides around outer surface 355.Groove 353 by the dust be captured between body 302 and nut 336 and chip from the connecting portion between body 302 and nut 336 downwards and outwards guide.This prevent dust and chip clings connecting portion and keeps body 302 can rotate on nut 336.

With reference to Figure 28 and Figure 28 A, rotary components 310 comprises brake apparatus 360, and this brake apparatus 360 is to be connected to body support section 308 releasedly with brake apparatus 24 and the similar mode of framework upper 16.But brake apparatus 360 comprises the lid 362 with pendency lug 364, and this pendency lug 364 has the connection feature different from lug 72.Lug 364 has round member 370, and round member 370 engages the coupling member 371 of body support section 308 and limits lengthwise movement and the rotary motion of the lid 362 of brake apparatus.More specifically, the round member 370 of lug has the outer surface 372 of inclination, and the outer surface 372 of this inclination engages with the inclined surface 374 of coupling member 371 to be rotated in the mode that mode lid 54 being locked to framework upper 16 is similar with rolling brake lid 54.The round member 370 of lug also has convex surface 376, and this convex surface 376 engages the concave surface 378 of coupling member 371.Surface 372 limits with the joint on surface 374 and the joint on surface 376 and surface 378 rotary motion and the lengthwise movement that lid 362 leaves its latched position.But will understand, sprinkler 300 can utilize the locking mechanism of sprinkler 10 alternatively.

Another difference between sprinkler 10 and sprinkler 300 is that sprinkler 300 has arm 312, and the cross section of this arm 312 is shaped as the rotary motion producing arm 312 in response to fluid impact arm 312.With reference to Figure 29, the current 380 from deflector 320 are advanced towards the inside of arm 312, the intermediate surface 384 of impact bending and outwards rebooting from the outside 386 of arm 312.The impact of current 380 pairs of curved surfaces 384 is applied with the power in Off-Radial direction, and this power produces moment of torsion on arm 312 and body 302.This moment of torsion makes body 302 advance along direction 309, and direction 390 is roughly contrary with the direction of rotation of deflector 320.

To understand, before the rotation of deflector 320 makes fluid stream 380 be moved into lose with arm 312 to aim at, fluid stream 380 only impacts arm 312 momently.Finally, fluid stream 380 impacts another arm and similar moment of torsion is applied in body 302 and arm 312 are incrementally rotated further.Therefore, deflector 320 (at least in part due to brake assemblies 360) moves along direction 392 with the speed of constant, and intermittent and incrementally rotate along direction 390 during any one arm in fluid stream 380 contact arm portion 312 of body 302 and arm 312.

With reference to Figure 30 to Figure 36, show sprinkler 1000, this sprinkler 1000 is all similar with the sprinkler 300 of Figure 24 to Figure 29 in many aspects.Sprinkler 1000 has nozzle 1002, and this nozzle 1002 has the lower threaded portion 1004 for being mounted to water supplying pipe line and the upper threaded portion 1006 for engaging with retaining member, such as bell tap 1008.Nozzle 1002 has two protuberances 1010,1012 that may be used for manually tightening/unclamping sprinkler 1000.

With the difference of sprinkler 300, sprinkler 1000 is that sprinkler 1000 has revolving body 1020, this revolving body 1020 is provided with fixing deflector 1022.This sprinkler comprises the snap fit feature portion 1023 deflector 1022 being releasably connected to revolving body 1020.Deflector 1022 shifts the injection stream from the water of nozzle 1002 and reboots the injection stream of water with two angles.An angle makes current from being vertically converted to level and making injection stream scatter for feeding water equably.As discussed below, rebooted by current and apply vertical force to deflector 1022, this makes revolving body 1020 compression braking device 1032 and the rotation of the revolving body 1020 that slows down.Deflector 1022 laterally applies the injection stream of water to form the moment arm around rotation 1033 to the second angular channel, thus makes revolving body 1020 (when from sprinkler 1000 top view) rotation clockwise.The shape of nozzle 1002 and deflector 1022 and configuration can change to produce different throwing distances and volume.

Bell tap 1008 has clip 1030, and clip 1030 is configured to allow brake apparatus 1032 and revolving body 1020 to be pressed against on bell tap 1008.But once brake apparatus 1032 and revolving body 1020 are arranged on bell tap 1008, even if nozzle 1002 removes from bell tap 1008, clip 1030 still limits brake apparatus 1032 and revolving body 1020 in order to avoid slide off bell tap 1008.

Brake apparatus 1032 is rubber two contact O type ring that can compress, and this O type ring will be produced the frictional force increased when compressing, and the frictional force of this increase prevents revolving body 1020 from constantly accelerating to rotate.When water slug deflector 1022 from nozzle 1002, the impulsive force from water makes revolving body 1020 be shifted to leave nozzle 1002 and make revolving body 1020 compression braking device 1032 and bell tap 1008 between the brake area 1040 and 1042 of revolving body 1020.

Revolving body 1020 has the collar 1050, and this collar 1050 has the internal tooth 1052 of smooth outer surface 1054 slip along bell tap 1008.Tooth 1052 is along the groove 1056 between tooth 1052 and outwards guide dust and other chips from the connecting portion between revolving body 1020 and bell tap 1008.This reducing sprinkler 1000 due to chip clings connecting portion between revolving body 1020 and bell tap 1008 and the possibility of stall.

With reference to Figure 40 to Figure 47, show the sprinkler 1200 of the brake assemblies 1202 had in response to environmental condition.Sprinkler 1200 is substantially similar to sprinkler 10 discussed above, thus focuses on the difference between sprinkler 1200 and sprinkler 10.As shown in Figure 47, brake assemblies 1202 has lid 1204, and this lid 1204 combines braking base component 1212 and forms closed chamber 1210.The accommodating fluid 1214 in room 1210 and brake axle 1216, this brake axle 1216 is connected to the deflector 1218 of sprinkler 1200.As shown in Figure 47, room 1210 can comprise seal to be sealed in room 1210 by fluid 1214 between brake axle 1216 and the axle area supported 1213 of braking base component 1212.

With reference to Figure 41, lid 1204 is removed the brake rotors 1230 that brake assemblies 1202 is shown.Brake rotors 1230 comprises reaction brake apparatus 1232, and this reaction brake apparatus 1232 is configured in response to the change of the environment residing for sprinkler 1200 and changes the brake force being applied to deflector brake axle 1216.Such as, reaction brake apparatus 1232 can comprise the coil 1240 that bi-material layers is made, and this coil 1240 has two the material synusia be laminated on together.With reference to Figure 46, show the cross section of coil 1240.Coil 1240 comprises driving part 1250 and passive components 1252, and wherein, this driving part 1250 has larger thermal coefficient of expansion, and this passive components 1252 has less thermal coefficient of expansion.Along with environment temperature increases, driving part 1250 expands to a greater degree than passive components 1252, and coil 1240 is expanded.

With reference to Figure 41 and Figure 42, coil 1240 has anchor portion 1260 and free end 1262, wherein, this anchor portion 1260 such as by solder joints in the slit of brake axle 1216, this free end 1262 is arranged radially outwardly from anchor portion 1260.With reference to Figure 41 and Figure 42, coil 1240 is shown as and has been in holosystolic position at low ambient temperatures, and in complete holosystolic position, the cross section of coil 1240 is directed around tightly holding ground each other.With reference to Figure 43 and Figure 44, coil 1240 is shown as at elevated temperatures in the configuration expanded completely.Compared with when coil 1240 is under low temperature, when coil 1240 is in the configuration expanded completely, coil 1240 coil spaced apart larger gap 1270.

Coil 1240 makes the opposing moment of torsion increase produced by coil 1240 when coil 1240 rotates in fluid 1214 to the change of complete expanded configuration from complete contracted configuration.More specifically, the opposing moment of torsion produced by the coil 1240 expanded is greater than the moment of torsion produced by shrinking coil.This increase of moment of torsion aspect is tending towards compensating the reduction of the viscosity aspect of the fluid 1214 that the rising due to environment temperature causes.Therefore, how the temperature regardless of surrounding environment changes, and coil 1240 can provide more consistent moment of torsion and produce the rotary speed of deflector 1218.

Shape another impact from contracted configuration to the change of expanded configuration of coil 1240 is that the moment of inertia of the coil expanded completely is greater than the moment of inertia of the coil 1240 of contraction.In other words, compared with when coil 1240 shrinks completely, coil 1240 is more difficult rotation when it expands completely.This increase of moment of inertia aspect also contributes to the reduction of the viscosity aspect compensating the fluid 1214 that the environment temperature owing to raising causes.

With reference to Figure 46 and Figure 47, fluid 1214 can for having the silica-based grease of required viscosity.With regard to driving part 1250, the metal or metal alloy including non-ferrous metal with high thermal coefficient of expansion can be used, such as copper, brass, aluminium or nickel.With regard to passive components 1252, the alloy of iron content can be used, such as stainless steel.

With reference to Figure 48, show another reaction brake apparatus 1290, this brake apparatus 1290 comprises the coil 1292 with the anchor portion 1294 being connected to brake axle 1216.Have lax configuration (see Figure 48) except coil 1292 and coil 1292 is had except the pressurized configuration (see Figure 49) of wavy shape, coil 1292 is all similar to coil 1240.When coil 1292 is in pressurized configuration, the corrugated profile of coil 1292 makes coil 1292 increase through the towing of the fluid 1214 in arrester 1210.

With reference to Figure 50 and Figure 51, show another reaction brake apparatus 1300.Reaction brake apparatus 1300 comprises beam 1302, and this beam 1302 extends from brake axle 1216 radially outwardly when reaction brake apparatus 1300 is in low environment temperature.But, as shown in Figure 51, increase temperature and beam 1302 is bent.Bending beam 1302 produces relatively large towing when advancing along direction 1304 in the fluid 1214 of beam 1302 in room 1210.Therefore, reaction brake apparatus 1300 provides the another kind of method of the reduction of the viscosity aspect of the fluid 1214 that the change for compensating due to environment temperature causes.Although only a beam 1302 is illustrated, the amount of resistance of reaction brake apparatus 1300 needed for application-specific can comprise an one, two, three or more beam 1302.

With reference to Figure 52, show another coil 1400.Except coil 1400 has the lips 1402 outwardly opposing moment of torsion produced by the coil 1400 expanded can amplified, coil 1400 is all similar to coil 1240.

With reference to Figure 53 to Figure 55, show another brake assemblies 1500.Brake assemblies 1500 can substitute brake assemblies 1202 and releasably be connected to sprinkler frame, such as framework 1203 (see Figure 40).Brake assemblies 1500 comprises housing 1502 and rotor 1506, and wherein, this housing 1502 has the room 1504 being filled with viscous fluid 1507 (see Figure 54) at least in part, and this rotor 1506 is arranged in room 1504.In one form, rotor 1506 is in cydariform, and room 1504 is filled with viscous fluid, and cylindrical rotor 1506 immerses in the viscous fluid in room 1504 completely.Viscous fluid 1507 or can have about 450 for grease, and 000cP (centipoise) is to another fluid of the viscosity in the scope of about 970,000cP.Such as, viscous fluid 1507 can for having the damping grease of the viscosity in the scope of about 450,000cP to about 550,000cP.Company as Nusil and Shin-Etsu and so on can be used as the grease of viscous fluid 1507.

With reference to Figure 53, housing 1502 has the lid 1503 being similar to lid 1204 (see Figure 40), and this lid 1503 is closed this room 1504 and comprised the pendency lug 1505 for being connected to sprinkler frame.But the top of lid 1503 is not illustrated to illustrate the internal part of brake assemblies 1500 in Figure 53.Lid 1204 in Figure 40 shows the top of lid 1503.More specifically, rotor 1506 is connected to axle 1510 in an end of axle 1510, and deflector 1512 is connected to the opposite ends of axle 1510.In response to deflector 1512 admitting fluid, deflector 1512 and axle 1510 rotate, and this makes rotor 1506 rotate in room 1504.Viscous fluid in room 1,504 1507 pairs of rotors 1506 produce towing, thus the rotation of the rotor 1506 that slows down when fluid impact deflector 1512 is to produce the rotary speed roughly in preset range of rotor 1506.

Brake assemblies 1500 also comprises reaction brake apparatus 1520, and in one form, this reaction brake apparatus 1520 comprises the bimetallic fin 1522 in the viscous fluid 1507 immersing room 1504 at least in part.As shown in Figure 54, fin 1522 has the free end 1552 separated with rotor 1506 by opening or gap 1524.When rotor 1506 being rotated when the rotation due to deflector 1512 along direction 1582, the viscous fluid 1507 in room 1504 is advanced along direction 1580 through gap 1524.

The position that the free end 1552 of fin changes in room 1504 in response to the change of the temperature aspect of bimetallic fin 1522, this changes the size in gap 1524---and viscous fluid 1507 is advanced through this gap 1524.The change of the temperature aspect of bimetallic fin 1522 can be due to brake assemblies 1500 around environment in the change of environment temperature aspect.The temperature that the change of environment temperature aspect can change viscous fluid 1507---bimetallic fin 1522 immerses in this viscous fluid 1507 at least in part---, this changes the temperature of fin 1522.Alternatively or except variation of ambient temperature, the temperature of viscous fluid 1507 can change in response to the rotation of rotor 1506 in viscous fluid 1507 (friction that such as, rotor 1506 at full speed rotates distance in fluid 1507 can increase the temperature of fluid 1507).In certain methods, the change (and change be associated of the temperature aspect of fluid 1507) of environment temperature is the main driver of the variations in temperature of bimetallic fin 1522, and the change in the temperature of fluid 1507 only contributes to the variations in temperature of fin 1522 slightly in response to the rotation of rotor 1506 in fluid 1507.In another method, a part for bimetallic fin 1522 can be exposed to surrounding environment, makes the change of environment temperature directly change the position of the temperature of fin 1522 and the free end 1552 of fin.

With reference to Figure 54, the viscous fluid 1507 in room 1504 roughly travels across gap 1524 along direction 1580 along path 1584 when rotor 1506 rotates.When the temperature of bimetallic fin 1522 such as increases due to the environment temperature increased, free end 1552 moves towards rotor 1506 along direction 1525, this make gap 1524 narrow (as in fin 1522 from its position among Figure 54 to as shown in the motion of its position in Figure 55).The viscous drag that this makes fluid 1507 produce in the gap 1524 narrowed increases, and the viscous drag of this increase compensates the viscosity of the reduction of the viscous fluid 1507 that the environment temperature owing to raising causes.When the temperature of bimetallic fin 1522 such as reduces due to the environment temperature reduced, free end 1522 leaves rotor 1506 along direction 1527 and stator 1530 (see Figure 53) towards detent housing 1502 is shifted, this make gap 1524 broaden (as in fin 1522 from its position among Figure 55 to as shown in the motion of its position in Figure 54).This makes the viscous drag produced by fluid 1507 reduce, and the viscous drag of this reduction compensates the viscosity of the increase of the viscous fluid 1507 that the environment temperature owing to reducing causes.Therefore, the function no matter how environment temperature changes the more consistent speed of rotation of the deflector 1512 all keeping rotor 1506 and be connected to rotor 1506 is played in the motion based on temperature of bimetallic fin 1522.

With reference to Figure 53, detent housing 1502 comprises pocket 1540 at stator 1530 and leads to the opening 1542 in pocket 1540.Each fin 1522 has the crooked end 1544 be arranged on rigidly in corresponding cylindrical shape pocket 1540.In one form, fin crooked end 1544 is by being frictionally engaged and remaining on tightly in housing pocket 1540 between crooked end 1544 and pocket 1540.In additive method, fin crooked end 1544 can utilize such as welding, securing member or adhesive to be fastened in pocket 1540.In another method, fin crooked end 1544 can be molded in stator 1530 in the molded period of housing 1502.

Each fin 1522 is all extended outwardly into room 1504 from its corresponding pocket 1540 by opening 1542.Each fin 1522 all has the base portion 1550 engaged with pocket 1540, and fin crooked end 1544 is positioned in detent housing room 1504.Fin 1522 has the shape with rotor 1506 complementation, and fin 1522 is all avoided and rotor interference in the whole opereating specification of the environment temperature experienced by sprinkler 1500.Such as, as shown in Figure 54 and Figure 55, fin 1522 can have concave inside surface 1560, and inner surface 1560 has the curvature similar with the curvature of the convex external surface 1562 of rotor 1506.

Reaction brake apparatus 1520 can have various forms.Such as, fin 1522 can be configured to move between the first location and the second location, wherein, in primary importance, fin free end 1552 is when sprinkler 1500 is in low environment temperature and rotor 1506 spaced apart (being similar to the position in Figure 54), in the second place, free end 1552 when sprinkler 1500 is in high environment temperature near or even directly contact rotor 1506 with the rotation of the rotor 1506 that slows down.

As shown in Figure 53 and Figure 54, fin 1522 is located to there is opening 1590 between adjacent fin 1522 about housing 1502 by detent housing stator 1530, and opening 1590 leads in the slit 1592 between fin 1522 and detent housing stator 1530.When fin free end 1552 is shifted towards rotor 1506, fin 1522 is left housing stator 1530 and is shifted, and fluid 1507 is drawn in slit 1592 along direction 1594 by this.When fin free end 1552 leave rotor 1506 move time, fin 1522 is shifted towards housing stator 1530, and fluid 1507 outwards extrudes from slit 1592 by this.

With reference to Figure 56 to Figure 58, show the deflector 1600 of another sprinkler.Such as, deflector 1600 can use together with brake assemblies 1200 and brake assemblies 1500.Deflector 1600 comprises entrance 1602 and outlet 1604, and wherein, this entrance 1602 is for receiving the fluid from sprinkler nozzle, and this outlet 1604 is for outwards discharging fluid from sprinkler when deflector 1600 rotates.Deflector 1600 comprises body 1606, and this body 1606 has exit opening 1608 and comprises the passage 1620 of conduit 1610.The part being received in the fluid at entrance 1602 place laterally reboots deflector 1600 is rotated from deflector 1600 by conduit 1610.As discussed in more detail below, the fluid of discharging from conduit 1610 provides extraly to the closely feedwater of surrounding terrain and the feedwater of middle distance.Remaining fluid outwards discharges from exit opening 1608 with the spray pattern limited by passage 1620 and exit opening 1608 by deflector 1600.As the configuration by passage 1620 and exit opening 1608 limit, the fluid of discharging from exit opening 1608 provides the remote feedwater to surrounding terrain.

With reference to Figure 57 and Figure 58, deflector passage 1620 has inner surface 1622, and this inner surface 1622 reboots towards the second direction 1626 of transverse direction the fluid received along first direction 1634.Deflector passage 1620 by provide fluid stream in deflector 1600 level and smooth reboot and make fluid from the outside throwing of exit opening 1608 apart from maximum.Particularly, channel inner surface 1622 turbulent flow that is configured to make to be applied to when fluid stream marches to exit opening 1608 from entrance 1602 this fluid stream is minimum.The turbulent flow of the reduction provided by passage 1620 makes fluid stream increase from the efficiency rebooted in 1624 to direction, direction 1626 and provide maximum throwing distance due to the less energy loss fluid stream in turbulent flow.Compared with the existing methods, the efficiency of this improvement allows sprinkler 1600 fluid of the less volume being supplied to sprinkler to feed water to the surrounding gardens of larger area.

With reference to Figure 58, conduit 1610 comprises and allows fluid to advance to opening 1630 in conduit 1610 along direction 163.With reference to Figure 56 and Figure 58, conduit 1610 also comprises closely feed water inclined-plane 1640 and middle distance feedwater inclined-plane 1642.A part for the fluid stream of advancing between entrance 1602 and exit opening 1608 drawn by conduit 1610, and inclined-plane 1640,1642 laterally reboots a described part for fluid stream, this makes the spray pattern of deflector 1600 broaden and allows deflector 1600 to the wider position feedwater around sprinkler.More specifically, inclined-plane 1640,1642 laterally reboots fluid, and this fluid-phase making the fluid of advancing along inclined-plane 1640,1642 and leave exit opening 1608 is than outwards advancing shorter distance and provide distance from deflector 1600 carries out and feed water and closely feed water.As shown in Figure 58, inclined-plane 1640 and the middle distance of closely feeding water feed water compared with inclined-plane 1642 and laterally bends larger amount.Compared with rebooting with the side direction applied by inclined-plane 1642, the larger lateral thrust amount on the inclined-plane 1640 that closely feeds water is applied with side direction greatly to the fluid of advancing along inclined-plane 1640 and reboots.Therefore, the water leaving conduit 1610 along inclined-plane 1640 is not outwards advanced far away as advanced along feedwater inclined-plane, centre 1642 in water from deflector 1600.Therefore, deflector 1600 provides closely feedwater and middle distance feedwater by guiding fluid along inclined-plane 1640,1642.By this way, inclined-plane 1640,1642 and exit opening 1608 provide the different throwing distance that fluid leaves deflector 1600.

In addition, because the wall 1643 of the part drawn by conduit 1610 near deflector 1600 before entering conduit 1610 of fluid stream is advanced, therefore a described part for fluid stream and the remainder of fluid stream have lower speed.Due to the viscosity of fluid (this fluid can be water), fluid stream has lower speed near wall 1643 and has higher speed away from wall 1643.Fluid rate when fluid rate when the lower initial rate entering the fluid of conduit 1610 contributes to making fluid to leave inclined-plane 1640,1642 leaves outlet 1608 lower than fluid, and reduce the throwing distance that fluid leaves inclined-plane 1640,1642.

With reference to Figure 59, show another sprinkler 1700.Sprinkler 1700 comprises framework 1702, and this framework 1702 has the upper socket 1704 receiving brake assemblies 1706 and the lower socket 1708 receiving nozzle 1710.Sprinkler 1700 also comprises deflector 1712, and this deflector 1712 is arranged on the axle 1714 of brake assemblies 1706.With reference to Figure 60, deflector 1712 has entrance 1750, exit opening 1724 and passage 1720, wherein, this entrance 1750 is for receiving the fluid from nozzle 1710, this exit opening 1724 is for outwards discharging fluid from deflector 1712, and entrance 1750 is connected to exit opening 1724 by this passage 1720.With reference to Figure 62, deflector 1712 comprises infundibular segment 1752, and this infundibular segment 1752 to play in the passage 1720 fluid from nozzle 1710 being directed to deflector 1712 and finally from the function that exit opening 1724 outwards guides.

As shown in Figure 61, passage 1720 has end difference or inclined-plane 1722, and the different piece that end difference or inclined-plane 1722 play to the water leaving exit opening 1724 gives different throwing distances and the function of spray pattern.Inclined-plane 1722 provides water from exit opening 1724 to the more uniformly distribution in around gardens, this by reduce to the excessive feedwater in around gardens or feedwater not enough and improve efficiency.Inclined-plane 1722 comprises fan-shaped feedwater inclined-plane 1730,1732 on the relative both sides of exit opening 1734.The inclined-plane 1730,1732 that closely feeds water makes the fluid side of the relative both sides leaving deflector opening 1734 outwards scatter fanwise and provides the even feedwater to around gardens.Inclined-plane 1722 also comprises primary flow channel 1740, this primary flow channel 1740 by the relatively little component of tangential motion roughly straight line outwards guide fluid.In addition, inclined-plane 1722 comprises middle distance feedwater inclined-plane 1742, and in this, distance feedwater inclined-plane 1742 makes fluid slightly laterally (but than the less degree side direction in inclined-plane 1730,1732) fan and contribute to more uniformly feeding water from deflector 1712.By this way, the region of deflector 1700 environment towards periphery provide evenly fluid distrbution, this by reduce excessively feedwater or feedwater not enough and improve efficiency.

Primary flow channel 1740 is configured to the track to providing part vertical along passage 1740 and from the fluid stream that exit opening 1724 is outwards advanced.In one form, the fluid of advancing along passage 1740 have relative to install sprinkler 1700 time the scope of horizontal about 5 degree to about 24 degree in track (wherein, from nozzle 1710 outflow fluid stream be vertical).

As shown in Figure 59, the vertical fluid stream from nozzle 1710 is rebooted into the fluid stream of the more level of outwards advancing from deflector 1712 by deflector 1712.In order to realize this rebooting, the passage 1720 of deflector 1712 is roughly bending between entrance 1750 and outlet 1722 along circular arc.With reference to Figure 62, this change be forced on the direction of fluid stream makes the segment fluid flow stream in fluid stream scatter towards the wall 1755,1757 of passage 1720 (comprising inclined-plane 1722).As shown in Figure 61, inclined-plane 1730,1732,1742 is caught the fluid that scattered and is outwards rebooted for deflector exit opening 1724 side direction by this fluid-phase.

With reference to Figure 62, inclined-plane 1722 comprises initial ramp 1745 and drives inclined-plane 1747, and this initial ramp 1745 and this driving inclined-plane 1747 produce the rotation of deflector 1712 when fluid travels across passage 1720.More specifically, initial ramp 1745 receive from entrance 1750 fluid at least partially and against driving inclined-plane 1747 guide fluid.Reaction torque is produced when driving inclined-plane 1747 to be oriented at fluid impact driving inclined-plane 1747.This impact makes deflector 1712 rotate.

With reference to Figure 59 and Figure 60, deflector 1712 has fin 1749, and this fin 1749 is configured to the object limited in surrounding environment and such as grows grass in order to avoid to become in the gap 1751 be stuck between framework 1702 and deflector 1712 and to suppress the rotation of deflector 1712.On the one hand, fin 1749 has the height (as shown in Figure 59) that gap 1751 is narrowed, and which reduces the potential article that may be fitted in gap 1751.In addition, fin 1749 has angled nose 1753, and this angled nose 1753 can push the article such as to grow grass and so between post 1745A, 1745B being captured in framework 1702 open.

Deflector 1712 controls by brake assemblies 1706 relative to the rotary speed of sprinkler frame 1702.With reference to Figure 64, brake assemblies 1706 comprises rotor 1760 and housing 1762, and wherein, this rotor 1760 is connected to axle 1714 or is even combined into one with axle 1714, and this rotor 1760 is mounted to housing 1762.Rotor 1760 rotates in the room 1764 limited by housing 1762, and this room 1764 is filled with viscous fluid 1766.Viscous fluid 1766 in room 1764 applies drag to set up rotor 1706 (and the deflector 1712 connected) the predetermined rotary speed in the particular range of the supply pipeline pressure for sprinkler 1700 on rotor 1760.

Brake assemblies 1706 has seal 1770, and the seal 1770 provides protection in order to avoid chip enters area supported between support plate 1772 and axle 1714 while allowing axle 1714 to rotate by viscous fluid-sealed in room 1766.Seal 1770 is mounted to support plate 1772, and this support plate 1772 is fastened to again the wall 1774 of housing 1762.Seal 1770 can be made up of silicon rubber, and housing 1762 can be made of plastics.In order to assemble brake assemblies 1706, viscous fluid 1766 being positioned in room 1764, making rotor 1760 proceed in room 1764, making the opening 1771 of seal 1770 (seal 1770 is arranged on support plate 1772) pass along axle 1714 and support plate 1772 is fastened to wall 1744.Support plate 1772 can utilize such as adhesive, securing member, be clasped or ultra-sonic welding techniques is fastened to wall 1744.

With reference to Figure 65, detent housing 1762 comprises the cylindrical wall 1780 of partly delimit chamber 1764 and wall 1780 is connected to the outward extending support 1782 of housing wall 1774.By this way, detent housing 1762 is that rotor 1760 and viscous fluid 1766 provide rigidity and durable environment, facilitates effective assembling process simultaneously.

With reference to Figure 59, sprinkler 1700 has locking mechanism 1784, and this locking mechanism 1784 is for being releasably fastened under framework in socket 1708 by nozzle 1710.As shown in fig. 66, lower socket 1708 comprises wall 1786, and this wall 1786 has from its outward extending coupling member 1788.Each coupling member 1788 all has following side, the recess 1794 that this following side has cam part 1790, stopper section 1792 and is formed on the following side of coupling member 1788.Go to Figure 67, nozzle 1710 has lid 1796 and pipe 1800, and wherein, this lid 1796 has skirt 1798, and this pipe 1800 dangles from lid 1796.Skirt 1798 has the component 1802 (see Figure 68) extending internally and have retainer 1803, and this retainer 1803 is configured to the coupling member 1788 of socket 1708 under engagement frame.Contrary with described component 1802, skirt 1798 has outward extending protuberance 1804, and protuberance 1804 is for grasping nozzle 1710 when user provides grip surface to be inserted into by nozzle 1710 user in lower socket 1708 and to rotate in this lower socket 1708.

With reference to Figure 66, blast tube 1800 is inserted in the opening 1812 of socket 1708 along direction 1810 by user, is only set to until the downside surface 1814 (see Figure 67) of lid is sat against the edge 1816 of socket wall 1786.Subsequently, user is along direction 1820 rotary nozzle 1710, and this makes nozzle arrangement 1802 and retainer 1803 thereof engage with socket coupling member 1788.First, each retainer 1803 engages the cam part 1790 of corresponding coupling member 1788, and due to retainer 1803 and the cam engagement of cam part 1790 along with the rotation of nozzle along direction 1820 moves down along direction 1810.Because the downside surface 1814 of lid rests on socket edge 1816, therefore retainer 1803 move down due to retainer 1803 and the cam engagement of cam part 1790 to the skirt 1798 of nozzle apply tension force and compression cover downside surface 1814 against socket edge 1816.

Nozzle 1710 makes retainer 1803 slide along coupling member 1788 along being rotated further of direction 1820, until retainer 1803 contactor banking stop portion 1792.User discharges nozzle 1710 subsequently, and the tension force in the skirt 1798 of nozzle pulls along direction 1832 retainer 1803 against the recess 1794 of coupling member 1788 and thus retainer 1803 put against recess 1794 seat.Although the downside surface 1814 of lid keeps compression against socket edge 1816, the recess 1794 of coupling member 1788 still allows retainer 1803 to be shifted along direction 1832 slightly upward, and this makes some tension force in skirt 1798 alleviate.Now, retainer 1803 is roughly held against the recess 1794 between the stopper section 1792 and cam part 1790 of corresponding coupling member 1788.Retainer 1803 and the joint of coupling member 1788 make the downside surface 1814 of lid keep playing against socket edge 1816 function be sealed in by nozzle 1710 in socket 1708 tightly.In addition, nozzle retainer 1803 and socket recess 1794 are configured to engage and thus stop nozzle 1710 along the rotation in direction 1830.

In order to be discharged from socket 1708 by nozzle 1710, user grasps lid 1796 and along direction 1830 rotary nozzle 1710, which overcomes the joint of retainer 1803 and recess 1794.Nozzle 1710 makes retainer 1803 slide off recess 1794 and cam part 1790 along corresponding coupling member 1788 is slided, until retainer 1803 leaves coupling member 1788 along the rotation in direction 1830.User subsequently can by upwards promoting nozzle 1710 along direction 1832 and being removed from socket 1708 by nozzle 1710, and pipe 1800 is also extracted out by this in socket 1708.

With reference to Figure 69 to Figure 73, show another sprinkler 2000, this sprinkler 2000 has deflector 2002, framework 2004, the socket 2006 of framework 2004 and nozzle 2008, and this nozzle 2008 is releasably fastened in socket 2006.Nozzle 2008 and socket 2006 are threadedly engaged, and make nozzle 2008 to be easily connected with socket 2006 and to disconnect.Sprinkler 2000 can be assembled with several nozzles 2008, and each nozzle all has different flow rates, makes sprinkler 2000 can easily adjust to be suitable for specific application.

More specifically, as shown in figure 70, socket 2006 comprises for receiving the opening 2010 of nozzle 2008 and getting around the wall 2012 of mouth 2010 extension.Wall 2012 is formed with external screw thread 2014, external screw thread 2014 has multiple helical pitch 2016.Similarly, nozzle 2008 comprises the lid 2030 (see Figure 71) with skirt 2032, and this skirt 2032 has internal thread 2034 and multiple helical pitch 2036.In one form, socket screw thread 2014 has four helical pitches 2016, and nozzle cover screw thread 2034 has six helical pitches 2036.By utilizing multiple helical pitch 2016,2036, sprinkler 2000 has the higher-strength for being held in place in socket 2006 by nozzle 2008 during the high pressure condition in the supply pipeline be associated.

The fewer number of of the helical pitch 2016 on socket 2006 is attributable to the par 2040 on wall 2012.Par 2040 strides across opening 2010 diametrically relatively and interrupted screw thread 2014.Par 2040 provides the grip areas for spanner, make user spanner can be connected to socket 2006 and rotating frame 2004 so that sprinkler 2000 is threaded on such as standpipe.Par 2040 is optional and may be used for improving molded easness.

With reference to Figure 73, sprinkler 2000 comprises sealing mechanism 2050, and sealing mechanism 2050 is for the formation of the water-tight seal between socket 2006 and nozzle 2008.In one form, as shown in Figure 72, sealing mechanism 2050 comprises annular protrusion 2052, and this protuberance 2052 extends internally from the inner surface 2054 of socket wall 2012.Protuberance 2052 defines the diameter 2056 that stride across opening 2012 narrower than the diameter 2058 of the opening 2012 in the tight downstream striding across protuberance 2052.With reference to Figure 71, nozzle 2008 comprises the pipe 2060 with upstream end thereof 2062, and this upstream end thereof 2062 has diameter 2064.The upstream end thereof diameter 2064 of nozzle 2008 is greater than the diameter 2056 limited by the protuberance 2052 in socket 2006.The larger diameter 2064 of blast tube 2060 and the less diameter 2056 of socket protuberance 2052 form the interference engagement between blast tube 2060 and socket protuberance 2052.Interference engagement plays the function forming the water-tight seal between blast tube 2060 and socket protuberance 2052 when nozzle 2008 is fastened in socket 2006.Different from the sprinkler seal of some routines, seal between blast tube 2006 and socket protuberance 2052 is substantially not by high supply pipeline pressure influence or plastic deformation (or material hardening, or the material creep) impact that do not stand when it is under continuous prestrain by material.

In order to nozzle 2008 is fastened in socket 2006, first blast tube 2060 to be positioned in receptacle openings 2012 and blast tube 2060 to be proceeded in socket 2006 along direction 2066, until nozzle threads 2034 arrives socket screw thread 2014 (see Figure 72 and Figure 73) by user.User's rotary nozzle 2008 nozzle threads 2014 to be engaged with socket screw thread 2034, and is rotated further nozzle 2008 to be tightened to completely in socket 2006 by nozzle 2008.When user's rotary nozzle 2008, nozzle 2008 is drawn in socket 2006 along direction 2066 by joint between screw thread 2014,2034 further.In addition, rotary nozzle 2008 makes blast tube upstream end thereof 2062 advance into along direction 2066 to contact with the annular protrusion 2052 in socket 2006.Being rotated further of nozzle 2008 causes protuberance 2052 to make upstream end thereof 2062 inwardly carry out camming movement and constricting nozzle pipe upstream end thereof 2062 along direction 2070,2072.Nozzle 2008 is preferably made up of the material based on polymer, and nozzle 2008 has following elastic performance: described elastic performance is tending towards resisting the compression to pipe 2060 that causes because of protuberance 2052 and described elastic performance makes pipe upstream end thereof 2062 outwards be biased along direction 2074,2076.Blast tube 2060 firmly engages with socket wall protuberance 2052 by this operation, form the interference engagement between socket 2006 and nozzle 2008 and play the function forming sealing between blast tube 2060 and protuberance 2052.In addition, when the fluid pressure of nozzle 2008 upstream increases (as shown in Figure 73, this makes the pressure increase in the chamber 2081 of pipe 2060), pipe 2060 outwards presses along direction 2074,2076 with larger power, and this makes sealing load increase.

With reference to Figure 74, show another nozzle 2100.Nozzle 2100 comprises the flow controller 2110 with opening 2112, and the diameter of this opening 2112 changes in response to the change of the fluid pressure in the upstream region 2114 of nozzle 2100.Flow controller 2110 is configured by and makes opening 2112 shrink (under higher supply pipeline pressure) or opening 2112 is expanded change that (under lower supply pipeline pressure) compensates supply pipeline pressure, all rotates with the rotary speed of constant this contraction or expansion have adjusted the volume flow of the fluid impacting deflector 2002 and makes the change of deflector 2002 supply pipeline pressure when no matter how.In one approach, during the operation of sprinkler 2000, supply pipeline pressure per square inch 15 pounds with the scope of 50 pounds per square inch in change.

Particularly, nozzle 2100 comprises lid 2102 and grommet 2116, and wherein, this lid 2102 has edge 2104, and this grommet 2116 has the perimeter 2118 engaged with nozzle edge 2104.Grommet 2116 has interior zone 2120, is formed with opening 2112 in this interior zone 2120.Grommet 2116 allows interior zone 2120 outwards to bend in response to the pressure increase in upstream region 2114.When the upstream fluid pressure of nozzle 2008 increases, the fluid pressure of increase makes grommet interior zone 2120 be bent in downstream substantially as the position 2122 shown in the dotted line in Figure 74.In deflected position 2122, interior zone 2120 has the opening 2112A of belt restraining, and the diameter of this opening 2112A is less than and is in Figure 74 with the diameter of opening 2112 during non-deflected position shown in solid line at grommet interior zone 2120.The opening 2112A of belt restraining allows the fluid reducing volume to leave opening 2112 along direction 2130.This operation of grommet 2116 play by reduce impact be associated deflector, such as deflector 2002 the volume of fluid compensate the function of the increase of supply pipeline pressure.Such as, if there is peak value in upstream fluid pressure, then grommet 2116 responds by bending in downstream, this bend opening 2112 and impact deflector 2002 water volume in form constraint, make deflector 2002 all continue to rotate with the speed of constant how high upper water pressure is when no matter.Grommet 2116---can such as have the silicon rubber of the hardness range of about 50 shore hardness A to about 70 shore hardness A---by flexible material and make.

Another nozzle 2200 has been shown in Figure 75.Nozzle 2200 comprises the lid 2202 with edge 2204 and the pipe 2206 dangled from lid 2202.Blast tube 2206 has upstream region 2210, this upstream region 2210 be sized to allow resilient disc 2212 insert along direction 2214 and the downside 2216 of abutment edges 2204 sit put.Pipe 2206 also comprises annular recess 2220 and ring 2224, and wherein, this annular recess 2220 extends around 2206 in the upstream of resilient disc 2212, and this ring 2224 to be configured to snap fit onto in pipe recess 2220 and to be remained in nozzle 2200 by resilient disc 2212.As shown in Figure 75, dish 2212 has opening 2230, and coils 2212 and bend to position 2232 in response to the fluid pressure of the increase in upstream region 2210.In deflected position 2232, dish 2212 has the opening 2230A of belt restraining, and in response to the supply pipeline pressure of the increase of the upstream of nozzle 2200, the diameter of this opening 2230A is less than the diameter of opening 2230, this reduces the flow by coiling 2212.
