The structure of above-mentioned gas cylinder and market are existing similar, will not give unnecessary details in this.About members such as the container of load bearing fluid and spray guns, to be described below respectively: see also shown in Figure 1, container 1 is the spatial accommodation that frame wall 103 frames with thickness surround closed state, has the feeding port 13 of loaded with liquid to this spatial accommodation, and this feeding port 13 is sealed with lid 30.Outside frame wall 103, have grip part 10, can recommend container 1 for people and carry out carrying behavior and the accessory of protection on the container 1, utilize the feeding port 13 or the tap 16 that are communicated to inner spatial accommodation, liquid filling is replenished or leaks remove to extraneous.Wherein, a kind of datonation-inhibition thing 101 is filled in container 1 inside, this datonation-inhibition thing 101 is stacked as similar cellular structure by the mesh elementary layer, this interior of the container is divided into many small compartments, has the resistance of holding back effect for flame transmission, and release heat is absorbed for this cellular each mesh unit in the burning, has good thermal conductivity, can reduce liquid, the hot swollen extent of reaction that rises that is produced of gas chance effectively, cause the force value amplification of container little, reach the effect and the purpose that suppress blast.

This container 1 also designs the meter 12 of measuring the air pressure inside size, for liquid through flow control valve 14 and carrier pipe 17 pipelines for outwards or the conveying of inwardly circulation, can be used as air pressure inside is leaked or the siphunculus 11 of air inlet or exploration vessel 1 internal liquid storage and hand increases air pressure one by one to container 1 inside booster 15 fast.Wherein, the epimere 111 of this siphunculus 11 extends outside the container 1, can optionally connect thereon establish a valve 113 and (or) amount of liquid detecting bar plant mouth 114.For avoiding detecting bar 115 suffers datonation-inhibition thing 101 when carrying out the storage of liquid obstruct inconvenience detecting, the hypomere 112 of this siphunculus 11 extends the inside of container 1, and in siphunculus 11, detect bar 115 from amount of liquid detecting bar plant mouth 114 places plant one, can borrow the detecting storage that bar 115 conveniently be inspected liquid in the container 1.This valve 113 has check valve (not painting among the figure) for tubulose, when container 1 internal gas pressure desire is released outward from valve 113, promptly stopping up whole pipeline to pushing away on this check valve can't be unimpeded, and the article that must utilize stock thing and so on just can reach the quick pressure releasing purpose by the past interior pushing of openend.This moment is if the article that control functions such as similar magnetic valve, air compressor, change-over switch, pressure regulating valve are installed on this valve 113, promptly have the function of automatic or semi-automatic quick air inlet and pressure release.Certainly, can select duty one or whole the use according to need about amount of liquid detecting bar plant mouth 114, detecting bar 115 and valve 113.

Above-mentioned booster 15 is the hollow tubes 151 that are connected container 1 by the outside with spiro union portion 152, less and the openend of its internal diameter is that an end of screw thread body gos deep in this container 1, an optionally external coupling assembling 70, other end internal diameter can be formed for the push rod 155 cross-under spiral shells of pushing valve 154 admittedly for the end more greatly.Wherein, this push rod 155 places an elastic parts 156 and end connection handle 153 outside exposed pipe, with manpower bestow this handle 153 through push rod 155 interlocks pushings valve 154 do to go up roping moving during, gas in this body 151 converges than small end because of crowding-out is pushed toward internal diameter, when again this pushing valve 154 being made downward motion, make the cause that gas can not adverse current because of pushing valve 154 utilizes pumping chamber 102 and check valve 158, cause to be positioned at body 151 internal diameters and to press down with this valve than the gas of small end and be discharged into outside the pipe.Making piston type by the pushing valve 154 of exerting pressure in body moves back and forth, utilize the interior gas of body during retracting, can pass through, the action that during extruding, can't pass through, in the mode that strengthens internal tank air pressure liquid is sent to flame by efferent duct and produces utensil, or the connection efferent duct is back in the container 1 residual liquid.

Above-mentioned coupling assembling 70 is spiro union portion or the Plug Division that connects booster 15 by hollow form cylindrical shell one end, and the other end is constituted by the convergence hole of extraneous aperture greater than inner aperture, to be connected with nozzle 4.In Fig. 2, the above-mentioned gas that is urged valve 154 extruding and discharges than small end from booster 15 internal diameters, can enter container 1 in the opening-like isolation ward 163 of inner recess, the openend of this isolation ward 163 is that booster 15 lockings form a closed space, the gas that enters this chamber only can flow in the containers 1 according to the air admission hole 157 of the direction of arrow from the top, for prevent gas by feeding port 13 release the external world must with lid 30 sealed it.

Converge in airtight gas zone 161 as container 1 top, except the fluid zone 162 to the below form pressure impel its be circulated to efferent duct that the bottom has a filterability net 143 through flow control valve 14 to carrier pipe 17, can be measured device 12 measurement of inductances clearly to indicate the air pressure size, also can learn what of amount of liquid, and attempt to locate to seek the crack and lead off through valve 113, lid 30 etc. through the detecting of detecting bar 115.Wherein, this valve 113 is sought the identical cause of the crack direction of extrusion with air pressure, and can't be released the external world from valve 113 because of check valve stops up travel direction by input to output; In other words, unless execute the strength of an anti-pressure directions with the stock thing and push check valve open and cause slot from exposed output, air pressure can be led off fast to the container external world, otherwise container 1 air pressure inside is bigger, check valve is subjected to this air pressure power-assisted in the same way in the valve 113, will to output pushing stop up consolidation more.

See also Fig. 4, Fig. 5, and cooperate shown in Figure 3, above-mentioned lid 30 its constituent components comprise a pedestal 31 that cross section is T-shaped, the bottom can be nested with stuffing hole 13 openends of packing ring 301 screw locks at said vesse 1, the top encompasses round to form a peristome 311 with wall thickness, this peristome 311 is extruded with annular projection portion 312 in the plane, top, and run through a connecting hole 313 in central authorities, this below, hole is for smaller aperture due end 315 and vertically by the outer resistance ring 314 that is extended with convex shape toward in, and the sheet 321 of pressing that can be consolidated with ductile material for a side touches.

This is pressing sheet 321 other sides to be extended with the guide bar 322 that can place a spring coil 323 vertically, on this guide bar 322, offer a through hole 3221, covered by a locking closure 324 that has endoporus 325 and be screwed onto said base 31 connecting holes 313, the aperture of this endoporus 325 is an end is slightly larger than guide bar 322 greater than the other end and smaller aperture due end diameters, spring coil 323 can be resisted and press generation elasticity strength on the sheet 321, pressing sheet 321 and guide bar 322 then can in endoporus 325, make shift movement vertically, in order to form an inductive component 32.

Said base 31 is behind the inductive component 32 that is spirally connected, a discoid emulsion sheet 33 can be held and be seated on the peristome 311, the lug boss 333 of ring-type then is equipped with in these emulsion sheet 33 lower ends, the cause that this emulsion sheet 33 supports to arrive in because of lug boss 333, its bottom surface and peristome 311 end faces are formed with a space that is equivalent to these lug boss 333 height, and be provided with the perforation 331 that several can directly be locked in peristome 311 for the thing that is spirally connected such as bolt, have at least a perforation 331 must keep straightway state, in order to be communicated with above-mentioned height space, utilize the screw part 332 of emulsion sheet 33 central authorities projection vertically again, connect a knob 34 and cooperate nut 302 lockings, promptly finish the assembling of lid 30.

Offer through holes 3321 in the middle of the screw part 332 that above-mentioned emulsion sheet 33 central authorities stretch along aixs cylinder, the guide bar 322 that sheet 321 in these through hole 3321 voltage supply places, and this protrudes out after pressing the guide bar 322 of sheet 321 to place the through hole 341,3021 of knob 34 and nut 302 again, utilize a draw ring 35 to be fixedly arranged on through hole 3221 places that offered on the guide bar 322 again, lift ring 35 and simultaneously with guide bar 322 and pressing sheet 321 to be pulled upwardly by upwards drawing, utilize manually the mode of control to carry out container 1 internal gas to lead off and can reach.

The lower end of said base 31 fixed block 361 that locks, on fixed block 361, offer through hole 362,363 respectively, wherein, through hole 362 is locked in pedestal 31 bottoms, and through hole 363 connects a chain (or rope lock) 364, and connect at the end of chain (or rope lock) 364 and to establish a limited block 365, form a limit assembly 36 therefrom.

The limited block 365 of above-mentioned limit assembly 36 places in the container 1, make when lid 30 adds liquid taking off, be buckled in the container 1 inner opening place of stuffing hole 13 because of limited block 365 tops, and pulling and supporting by chain (or rope lock) 364, make lid 30 be suspended in outside the container 1, reason lid 30 does not take off and is difficult for seeking.

The above-mentioned gas that converges in the container 1 is attempted also can seek the crack in the hope of leading air pressure off from stuffing hole 13 when valve 113 is sought the crack and led off.Suppose that lid 30 is an input with the smaller aperture due end 315 of pedestal 31, smaller aperture due end with locking closure 324 endoporus 325 is an output, then inductive component 32 pressing sheet 321 be from output to the input direction for stopping up motion, utilize the elastic force piezometric system of spring coil 323 to touch in the end of resisting ring 314, with valve 113 be to stop up motion by input to the output direction, the two is opposite fully.

Along with the increase gradually of said vesse 1 internal gas, make the obstruction campaign of inequality that distinct effect be arranged.Air pressure is bigger, in the valve 113 check valve because of air pressure helping of thrust in the same way, will stop up more consolidation and can't leading off discharge extraneous; But lid 30 just is opposite result, be that gas can form the strength of backing down passing to pressing sheet 321 to exert pressure from the input (the smaller aperture due end 315 of pedestal 31) of lid 30, simultaneously spring coil 323 can press sheet 321 to impose reverse compacting strength to this with the elastic force that pressurized produces, and two resist strenuously to make under the weighing apparatus and pressing sheet 321 to do following axial displacement campaign:

1. when thrust averages out state less than press power or two power are anti-mutually two kinds of situations are arranged then, if one need maintain the statusquo the time, is promptly pressing sheet 321 still to remain on to press and touch state with resisting ring 314, and displacement movement equals zero, so can prevent gas leak; They are two years old, if in the time of need carrying out that gas is led off in the container 1, then can manually upwards draw and lift ring 35 and simultaneously with guide bar 322 and pressing sheet 321 to be pulled upwardly, make and pressing sheet 321 and resisting ring 314 contact jaws formation slit, at this moment, gas promptly can be by slot along direction shown in Fig. 5 arrow, enter peristome 311 and emulsion sheet 33 the two formed height space through output (the smaller aperture due ends of locking closure 324 endoporus 325), and lead off to the external world from the perforation 331 that is communicated with this space, thereby utilizing the mode of manually controlling to carry out container 1 internal gas, formation leads off.

Thrust greater than press power the anti-mutually state of destruction of balance, this is pressing sheet 321 to be moved by ejection gradually, make and pressing sheet 321 and resisting ring 314 contact jaws formation slit, this slit enlarges gradually with the amplification of thrust, gas can be by slot along direction shown in Fig. 5 arrow because of pressure simultaneously, enter peristome 311 and emulsion sheet 33 the two formed height space through output (the smaller aperture due ends of locking closure 324 endoporus 325), and lead off to the external world from the perforation 331 that is communicated with this space.

3. along with the process that leaks of gas, air pressure will successively decrease gradually, this is pressing sheet 321 to progressively increase because of spring coil 323 is compressed elastic force acquisition release, under the guiding function of guide bar 322 and endoporus 325, little by little do axial displacement toward original position, the two resists when averaging out once again mutually up to thrust and counter power, is pressing sheet 321 to touch and to make the slit complete obiteration with resistance ring 314, in order to block the path of gas leak.Above-mentioned lid and valve difference are:

1. lid, gas can't ecto-entad be the unlatching of leading path off, only can moderately lead off to the external world, in case air pressure and counter power average out, can block automatically and lead path off, has the function of air pressure adjustment, the drawback that can avoid explodes injures human body produces; Or can manually reach the effect of leading gas off.

2. valve, gas can't be led off through valve outward by inside, but can utilize stock thing or mechanical implement to do the operation of manual mode such as semi-automatic or automatic, can inwardly open the valve check valve from the external world and form path or the pipeline that air pressure is led off, and lead speed system off and urgently and quickly be circulated to the external world, the mechanical implement that also can utilize air compressor or pressure regulator valve or magnetic valve and so on is by inwardly air inlet apace of valve, and this point is not had by lid.

Said vesse is the purpose of design so, but provide the booster of a kind of quick air inlet, disappointing gas nozzle structure, a kind of amount of liquid detecting bar plant mouth and detecting bar structure, a kind of air inlet and regulate the structures such as lid of air pressure, for user or the visual in force demand of operator or according to the ground use of electing property of custom based on the security consideration automatic or manual.

In addition, this booster 15 also has second purposes: the cleaning that promptly keeps gas, liquid transmission pipeline 17 is with unimpeded, the slightly following two kinds of situations of its using time pact:

A. whether opinion work is finished or wouldn't use the time, more or less can liquid residually be arranged in pipe in flow control valve 14 and the carrier pipe, can separate container 1 this moment with booster 15 becomes independent thing, the port of export direct than small end with its internal diameter and this carrier pipe 17 is spirally connected or pegs graft is one, produce gas and enter in the pipe with reciprocating type tension and compression campaign, interior retention of pipe or remaining liquid are back in the container 1 (consulting Fig. 3), to preserve for use next time.

B. when guaranteeing that use next time, carry the pipeline of gas, liquid unblocked, best mode is to utilize the external coupling assembling 70 of booster 15 less internal diameter ends, flame generator or spray gun 2 etc. has been reduced to closed on general skin and touch the unlikely nozzle of feeling high temperature, produce gas with reciprocating type tension and compression campaign, impel whole spray gun 2 and pipeline inside to retain or remaining liquid is back in the container 1 (please cooperate and consult Figure 15 and the shown in Figure 16).

Based on above-mentioned reason, the isolation ward 163 in this container 1 is in order to isolate contacting of booster 15 and liquid, to keep these booster 15 clean appearances, isolation; But, if container 1 inner volume is less or user when not needing the structural design of isolation ward 163, this isolation ward 163 be can give up no, and this moment, liquid then can be from the interface C input pod 1 interior (referring to Fig. 2, Fig. 3) of booster 15 outside spiro union portions 152 with container 1 bolt.

The annexation of above-mentioned coupling assembling 70 and nozzle can be by Figure 13, Figure 15, example be illustrated that Figure 16 lifts.Coupling assembling 70 in the legend is the cylindrical shells 72 that had spiro union portion 71 by an end, be connected with the socket piece 73 of hollow and annular at the other end with one of technological means such as sleeve, gluing or engaging, this socket piece 73 and spiro union portion 71 are isolated by hollow form ring partition 74 between the two to be organized structure and is formed; Wherein, the aperture of these socket piece 73 inner adjacent loops partition 74 1 ends is less than the aperture of the other end, form the convergence hole 75 of one breakthrough status, this convergence hole 75 is provided with several protuberances 76 along the diametric(al) spacer ring, when nozzle 4 inserts in this convergence hole 75, no matter how nozzle 4 extraneous shapes design, the convergence hole 75 that all can push socket piece 73 is done the distortion of corresponding shape, and each protuberance 76 is pressed and is touched in its surface in response to nozzle 4 profiles in the hole, connect the gas that boosters are bestowed for spiro union portion 71, with nothing leak may and in nozzle 4 pours into the transfer pipeline of whole gas or liquid.

Figure 14 shows that another formation of coupling assembling, be to utilize integrated technological means to make hollow form cylindrical shell 72, one end has spiro union portion 71, the other end is the coupling assembling 70 of convergence hole 75, the aperture of these convergence hole 75 contiguous spiro union portion 71 1 ends is less than the aperture of the other end, and being provided with several protuberances 76 along the diametric(al) spacer ring, its function, operating position and above-mentioned coupling assembling are identical, repeat no more in this.

In addition, the gas, the liquid that are taken up in aforementioned gas cylinder or the container 1 will form the thermal-flame air-flow, also must could produce the utensil use for flame through mixing, and below are the relative configurations that the applicant researches and develops.

The flame generator is shown in Fig. 6 A and Fig. 6 B, it is a kind of three-tube type spray gun 2, by handle 20 1 ends is the inlet portion 201 that air feed, liquid enter, the other end connects a head 24 with first efferent duct 21, second efferent duct 22 and the 3rd efferent duct 23 and sets up formation jointly, wherein, first efferent duct 21 is communicated with the gas cylinder that carries gas; Second efferent duct 22 is connected with gas cylinder; The 3rd efferent duct 23 is communicated with the container that carries liquid.The flow control valve 14 of said vesse 1 and carrier pipe 17 can be connected with valve 141 in the pipe, and has filter screen 142 between the inlet portion 201, to remove foreign material such as iron filings in the filter liquide, residue, avoid it to enter gas, unnecessary puzzlement or maintenance factor are caused in the liquid Mixed Zone.Wherein, the design of valve 141 is extremely important in this pipe, because the generation of tempering phenomenon normally has flammable material because retain in the pipeline, cause flame to follow line one tunnel and burn gas cylinder or container generation blast, and the closing of valve 141 in the pipe, with make its combustible that arrives this section of fire end with the existence of thermal-flame air-flow approach exhaustion, thus, the drawback of one of tempering occurrence factor may be removed disappearance.In addition, when changing flame and producing utensil, can close earlier that valve 141 flows out to block liquid in this pipe, just not replace and do not need container 1 air pressure released, can convenient welding or the carrying out of the work of cutting.
