On the other hand, the shape of the rear end side of the outer surface of nozzle casing 3 forms hexagon.It more than is the structure of nozzle casing 3.In addition, with reference to the axial length of Fig. 2 at rear discussion the 1st internal thread part 331 and the 2nd internal thread part 332.
It more than is the overall structure of the nozzle of present embodiment.
Then, with reference to Fig. 2, the using method of the nozzle of present embodiment is described.
At first, as prerequisite, supply pipe X is connected on the connecting portion 170 of rear end side of nozzle body 1.Nozzle body 1 and supply pipe X are threaded etc. by the thread groove that makes supply pipe X (omitting diagram) and the thread groove 171 of connecting portion 170 to be connected.At this moment, because the periphery of the 1st flange part 160 forms hexagon, therefore can use the instrument such as die nut to connect reliably nozzle body 1 and supply pipe X.
Shown in Fig. 2 (a), nozzle is that following installation forms: at first, in the periphery of the stroke section 150 of nozzle body 1 annular construction member 2 is installed, afterwards, O shape ring 141 is installed in the slot part 140 of nozzle body 1.Then, make outer being enclosed within on the O shape ring 141 of sliding part 240 of annular construction member 2, annular construction member 2 is made as with respect to the nozzle body 1 distolateral state that has advanced forward.
Then, shown in Fig. 2 (b), under the state of Fig. 2 (a), make nozzle casing 3 spinnings in the front of nozzle body 1.At this moment, be threaded with the 1st external thread part 131 of nozzle body 1 with the 1st internal thread part 331 of nozzle casing 3 and mode that the 2nd internal thread part 332 of nozzle casing 3 is threaded with the 2nd external thread part 232 of annular construction member 2 is determined the length of the thread groove of the length of thread groove of length, the 2nd external thread part 232 of stroke section 150 and the 2nd internal thread part 332.
Thus, even when annular construction member 2 is positioned at foremost side with respect to nozzle body 1, except the 1st external thread part 131 that can make nozzle body 1 is threaded with the 1st internal thread part 331 of nozzle casing 3, the 2nd external thread part 232 of annular construction member 2 is threaded with the 2nd internal thread part 332 of nozzle casing 3, can prevents reliably coming off of nozzle casing 3.
And, owing to connecting with O shape ring 141, the minor diameter 250 of annular construction member 2 becomes the anticreep state, therefore also can prevent the situation that the nozzle casing 3 that becomes one with annular construction member 2 and annular construction member 2 come off from nozzle body 1.
Therefore in addition, the 2nd flange part 260 of annular construction member 2 forms identical hexagon with the periphery of the rear end side of nozzle casing 3, can use the instrument such as die nut to connect reliably annular construction member 2 and nozzle casing 3.
Under the state of this Fig. 2 (b), have the gap between the 1st conical surface 110 of nozzle body 1 and the 2nd conical surface 310 of nozzle casing 3.Therefore, supplying with the fluid (for example water) that the comes outside by the helicla flute 111 of the 1st conical surface 110 from a plurality of intercommunicating pores 121 is supplied to and is filled in the nozzle casing 3.The fluid that is filled in the nozzle casing 3 sprays from the nozzle bore 300 of the front end of nozzle casing 3.
At this moment, the fluid that sprays from nozzle bore 300 sprays with this state by nozzle bore 300, therefore is the less linearity of jet angle.At this, because the front end through hole 101 of nozzle body 1 forms with nozzle bore 300 coaxial, therefore utilize the fluid that sprays coaxially from front end through hole 101, the fluid that is filled in the nozzle casing 3 can be guided to nozzle bore 300, the hydraulic efficiencies in the nozzle casing 3 are sprayed from nozzle bore 300 well.
Then, shown in Fig. 2 (c), rotate by from the state of Fig. 2 (b), nozzle casing 3 and annular construction member 2 being integratedly, the 1st internal thread part 331 of nozzle casing 3 is changed with the position that is threaded of the 1st external thread part 131 of nozzle body 1.Then, the 1st conical surface 110 of nozzle body 1 and the mode of the 2nd conical surface 310 butts of nozzle casing 3 are determined the length of the thread groove of the length of thread groove of the 1st external thread part 131 and the 1st internal thread part 331 so that nozzle casing 3 and annular construction member 2 retreat with respect to nozzle body 1.That is the mode that, the length of the thread groove of the length of the thread groove of the 1st external thread part 131 and the 1st internal thread part 331 distance that the nozzle casing 3 when the 1st conical surface 110 and the 2nd conical surface 310 butt moves to move than nozzle casing 3 is large is determined.
And, until the 2nd conical surface 310 butts of the 1st conical surface 110 of nozzle body 1 and nozzle casing 3, can determine in the mode that stroke section 150 slides the length of stroke section 150 with annular construction member 2.Namely, when the annular construction member 2 that becomes one with nozzle casing 3 retreats, for annular construction member 2 can not stopped with the 1st flange 160 butts before the 1st conical surface 110 and the 2nd conical surface 310 butts, the length of stroke section 150 is determined in the large mode of the scope that is threaded than the thread groove of the thread groove of the 1st external thread part 131 and the 1st internal thread part 331.
Thus, even the position (positions of the 1st conical surface 110 and the 2nd conical surface 310 butts) that the annular construction member 2 that becomes one with nozzle casing 3 is retreating with respect to nozzle body 1, except the 1st external thread part 131 that can make nozzle body 1 is threaded with the 1st internal thread part 331 of nozzle casing 3, the 2nd external thread part 232 of annular construction member 2 is threaded with the 2nd internal thread part 332 of nozzle casing 3, can prevents reliably coming off of nozzle casing 3.
In addition, when the nozzle casing 3 that becomes one and annular construction member 2 retreat with respect to nozzle body 1, annular construction member 2 with its minor diameter 250 as guiding piece, in the stroke section 150 of nozzle body 1 side shifting to the back-end.At this moment, the sliding part 240 of annular construction member 2 is with respect to being installed in O shape ring 141 on the nozzle body 1 take sealing state (in the situation that fluid is that water etc. is as liquid-tight state) slip.
Under the state of Fig. 2 (c), the 1st conical surface 110 of nozzle body 1 and the 2nd conical surface 310 butts of nozzle casing 3.Therefore, supplying with the fluid (for example water) that comes from supply pipe X supplies with to the helicla flute 111 between the 1st conical surface 110 and the 2nd conical surface 310 via a plurality of intercommunicating pores 121 from center culvert 100, and be directed to the leading section of nozzle casing 3 by helicla flute 111, spray from nozzle bore 300.
At this moment, the fluid that sprays from nozzle bore 300 is by helicla flute 111, thereby has under the state of centrifugal force, spray to circumferential foreign side from nozzle bore 300, so is larger radial of jet angle.In addition, at this moment, utilize from the front end through hole 101 of nozzle body 1 fluid in coaxial ejection, can comprise that also middle body sprays equably from nozzle bore 300.
On the other hand, for the state from Fig. 2 (b) and Fig. 2 (c) separates nozzle casing 3 from nozzle body 1 and annular construction member 2, by removing being threaded of the 1st external thread part 131 and the 1st internal thread part 331 and being threaded of the 2nd external thread part 232 and the 2nd internal thread part 332, nozzle casing 3 can separate from nozzle body 1 and annular construction member 2.
At this moment, because the 2nd flange part 260 of annular construction member 2 forms identical hexagon with the periphery of the rear end side of nozzle casing 3, so can remove simply being connected of annular construction member 2 and 3 of nozzle casings with instruments such as die nuts.Therefore, can separating nozzle cover 3, its inner surface, nozzle bore are cleaned etc. termly.
Above, at length be illustrated, adopt the nozzle of present embodiment, can prevent reliably coming off of nozzle casing, and maintainability is also excellent.
In addition, in the present embodiment, having illustrated that the fluid of supplying with via supply pipe X is the situation as the water of liquid, is situation as the water of liquid but be not limited to fluid, also can be the liquid (for example liquid) except water, also can be gas (for example air).
In addition, in the present embodiment, connecting portion 170 is outstanding to the rear of nozzle body 1, but is not limited thereto, and thread groove etc. also can be set at the inner peripheral surface of the 1st flange part 160 come spinning supply pipe X.
And, in the present embodiment, illustrated that containment member is the situation of O shape ring 141, but even the member of containment member except O shape ring, so long as the member that can seal gets final product.
