Detailed description of the invention:
Below in conjunction with specific embodiments and the drawings, the present invention is further described.
As Figure 1-Figure 4, of the present invention is a kind of anti-drip device of high-pressure water mist fire fighting shower nozzle, be arranged between high-pressure water mist fire fighting shower nozzle and water pipe, wherein, this anti-drip device comprises a cylindrical body 1, in the present embodiment by water (flow) direction from front end to the back-end, the bottom surface that the front-end and back-end of described cylindrical body 1 are provided with the first recess space 101 and the second recess space 101, recess space 102, first vertically respectively to centre is provided with the 3rd recess space 103 vertically further; Be connected with a connector 2 in the front end of described cylindrical body 1, connector 2 is threaded connection fixing with the leading section of cylindrical body 1; This connector 2 has the 4th recess space 201 holding described cylindrical body 1 leading section, and connector 2 offers through intake tunnel 202 vertically; First recess space 101 of cylindrical body 1 connects with the 4th recess space 201 of connector 2, therebetween be provided with a spool 3, main body (the i.e. maximum outside diameter section) external diameter of described spool 3 is suitable with the internal diameter in the first recess space 101, and therefore spool 3 can move vertically in the first recess space 101; The front end of spool 3 has the shutoff face 301 of the intake tunnel 202 of connector 2 described in shutoff, the rear end of spool 3 and the spacing Compress Spring 4 in the 3rd recess space 103 of radial direction inconsistent; Offer several the first water stream channels 104 being communicated with described second recess space 102 and the first recess space 101 by the bottom edge in described second recess space 102 along with axially parallel direction, and the first water stream channel 104 forms arc groove 105 on the inwall in described first recess space 101; Water stream channel 104 does not run through the front end face of cylindrical body 1, and the length of arc groove 105 is greater than the length of spool 3 main body, is namely greater than the length of spool 3 maximum gauge section.
By said structure, in use, be connected the outer end of connector 2 with fire extinguisher canvas hose, the second recess space 102 of cylindrical body 1 is connected with high-pressure water mist spray head.In a non-operative state, due to the elastic force of Compress Spring 4, spool 3 is withstood to connector 2 direction, make the shutoff face 301 of spool 3 front end block the intake tunnel 202 of connector 2, thus forbid that current lead to, the elastic force of Compress Spring 4 sets as required, only have when the hydraulic pressure in intake tunnel is greater than the elastic force of spring, current by spool 3 to backlash, the main body being always flushed to spool 3 enters in the first recess space 101, the arc groove 105 of the first recess space 101 sidewall is connected with the 4th recess space 201 before spool 3, namely the first water stream channel 104 is communicated with the 4th recess space 201 of connector 2, now current enter the first water stream channel 104 by along the arc groove 105 on the first recess space 101 sidewall, flow to the second recess space 102, again from the high-pressure water mist spray head be communicated with the second recess space 102 be vaporific ejection, shower nozzle enters duty, when injection completes, when hydraulic pressure reduces, spool 3 pushes up to connector 2 rapidly by Compress Spring 4, again blocks the intake tunnel 202 of tube connector 2, so just can prevent the water droplet remained in water pipe from leaking.
In the present embodiment, the front end of described spool 3 has in truncated cone-shaped, insert described connector 2 intake tunnel 202 rearward end before interpolating unit 31, the rearward end of described intake tunnel 202 is also in truncated cone-shaped, sidewall and the intake tunnel 202 rearward end inwall of front interpolating unit 31 are inconsistent, namely using the sidewall of interpolating unit 31 before truncated cone-shaped as shutoff face, intake tunnel is blocked.
The rear end of described spool 3 has the locating dowel 32 inserted in Compress Spring 4, is convenient to the assembling between Compress Spring 4 and spool 3.
The second through water stream channel 106 is offered to the bottom surface in the second recess space 102 vertically by the bottom surface in described 3rd recess space 103; Namely current also can pass through the first recess space 101, the 3rd recess space 103 and this second water stream channel stream 106 to the second recess space 102, by the water stream channel of multi-direction multiple-limb, avoid producing noise in high-voltage operation.
The default elastic force of described Compress Spring 4 is 10 bar, namely when water flow pressure is less than 10 bar, cannot promote spool, otherwise then can promote.
Or, as shown in Figure 5, Figure 6, the front end of described spool 3 has in truncated cone-shaped, inserts interpolating unit 31 before in described connector 2 intake tunnel 202, and the sidewall end of front interpolating unit 31 has the ring-type shutoff face 302 inconsistent with the bottom surface in described 4th recess space 201.In addition, as in Fig. 5, also can add sealing ring 33 at this ring-type shutoff face 302 place, guarantee shutoff further.
Moreover, as shown in Figure 7, in the bottom in described second recess space 102, a gland 5 is also installed, the inner face of this gland 5 offers the 5th concave surface space 501 communicated with the first water stream channel 104, and the middle part of gland 5 offers the through hole 502 in through 5th concave surface space 501 and the second concave surface space 102.The effect of gland 5 to be changed the direction of a stream of water, and can install and can not install, and is whether to install gland according to the type selecting of high-pressure water mist spray head, and gland 5 can be threaded connection mode and to install or jump ring mode is installed.
In sum, as long as anti-drip device of the present invention is when non-fire-fighting work state, the inlet channel 202 of connector 2 can be blocked by Compress Spring 4 and spool 3, cut off the current between water pipe and high-pressure water mist spray head, play antidrip effect, thus efficiently solve shower nozzle after having put out a fire and also cause dripping staff cannot enter on-the-spot puzzlement.In addition, internal structure special in anti-drip device of the present invention and water stream channel design, make whole high-pressure water mist spray head and anti-drip device can not produce noise in high pressure use procedure, accomplish tranquility environmental protection; Moreover, anti-drip device overall volume of the present invention is little, quality is light, can be directly connected between high-pressure water mist spray head and pipeline, exquisite appearance, therefore the present invention can be widely used in hotel's fire extinguishing, market fire extinguishing, station fire extinguishing, airport fire extinguishing, mobile fire-fighting fire extinguishing, press down fire, numerous areas such as control fire, temperature control etc., is also used in the places such as Archive, steamer machine room, computer floor be inflammable and explosive.
