Description

Rifle valve module

Technical field

It the utility model is related to giant technical field, more particularly to a kind of rifle valve module.

Background technology

Rifle valve module is the important component of giant, in existing rifle valve module, as shown in figure 1, in rifle valve pocket 1 Interior top is equipped with metallic carrier rod 2, is sequentially arranged with plastic sealing ring 3, steel ball 4 and spring 5 under it.When locking gun state, steel Pearl 4 is oppressed by spring 5, is close at the aperture of endoporus lower end of plastic sealing ring 3, and plastic sealing ring 3 and rifle valve pocket 1 Endoporus is interference fit, and the external and internal compositionses of such plastic sealing ring 3 prevent water from passing through with regard to that can seal up water under high pressure.In shooting shape During state, metallic carrier rod 2 is moved downward by the pressure of trigger, forces steel ball 4 also synchronously to move downward, and such water under high pressure is with regard to that can pass through The endoporus of plastic sealing ring 3, the delivery port of rifle valve pocket 1 is flowed through, then sprayed by barral of a gun or shower nozzle, with article-cleaning.

But ellipse is easily deformed into after the endoporus injection molded of plastic sealing ring 3 in the prior art, so it may result in It is poorly sealed when steel ball 4 is pressed in its aperture by spring 5, easily there is the bad phenomenon of leak.

The content of the invention

Technical problem to be solved in the utility model is：A kind of rifle valve module for being not easy leak is provided.

Technical scheme is used by the utility model：A kind of rifle valve module, including rifle valve pocket, in the rifle valve pocket successively Provided with push rod, seal and for the spring to seal offer pressure, the seal includes valve element and is set in valve Sealing ring outside core, and the sealing ring is engaged with the conical surface in rifle valve pocket internal taper hole.

Using above structure compared with prior art, the application has advantages below：It is replaced by valve element and sealing ring Preceding steel ball and plastic sealing ring, so only need after sealed ring deformation with cone match, without as before The endoporus of sealing ring must be processed into circle, it is thus preferable in the absence of the hidden danger of leak, sealing effectiveness.

Preferably, the excircle of the valve element is provided with a circle groove, and the sealing ring is set in the groove. Sealing ring is set in groove, such sealing ring so can will preferably play sealing effectiveness with valve core movement.

Preferably, the valve element is plastic poppet, and the sealing ring is rubber seal.Using rubber seal, So elasticity is more preferable, and then causes the more preferable of sealing ring and cone match, and sealing effectiveness is more preferable.

Preferably, the projection that ammunition feed spring is inserted in is additionally provided with the valve element.In this way, spring can preferably give valve element Pressure so that the sealing ring on valve element preferably coordinates with the conical surface, and sealing effectiveness is more preferable.

Brief description of the drawings

Fig. 1 is the sectional view of prior art rifle valve module.

Fig. 2 is the sectional view of the utility model rifle valve module.

As shown in the figure：1st, the rifle valve pocket in prior art rifle valve module；2nd, the push rod in prior art rifle valve module；3rd, it is existing There is the sealing ring in technology rifle valve module；4th, the steel ball in prior art rifle valve module；5th, the bullet in prior art rifle valve module Spring；6th, the rifle valve pocket in the application rifle valve module；7th, the push rod in the application rifle valve module；8th, the bullet in the application rifle valve module Spring；9th, the valve element in the application rifle valve module；10th, the sealing ring in the application rifle valve module；11st, in the application rifle valve module Groove；12nd, the projection in the application rifle valve module.

Embodiment

The utility model is described further with embodiment below in conjunction with accompanying drawing, but the utility model is not only It is limited to detailed description below.

A kind of rifle valve module, including rifle valve pocket 6, be sequentially provided with the rifle valve pocket 6 push rod 7, seal and for Seal provides the spring 8 of pressure, it is characterised in that：The seal includes valve element 9 and the sealing ring being set in outside valve element 9 10, and the sealing ring 10 is engaged with the conical surface in the internal taper hole of rifle valve pocket 6.

The excircle of the valve element 9 is provided with a circle groove 11, and the sealing ring 10 is set in the groove 11.

The valve element 9 is plastic poppet, and the sealing ring 10 is rubber seal.

The projection 12 that ammunition feed spring 8 is inserted in is additionally provided with the valve element 9.

During the operation principle of the application：When locking gun state, plastic poppet 9 is oppressed by spring 8, is close to rifle valve pocket 6 At the conical surface of corresponding taper hole, the rubber seal 10 on plastic poppet 9 is also pressed on the conical surface of the corresponding taper hole of rifle valve pocket 6 On, water under high pressure can be thus sealed up, prevents water from passing through.In the state of shooting, metallic carrier rod 7 is transported downwards by the pressure of trigger It is dynamic, force plastic poppet 9 also synchronously to move downward, rubber seal 10 thereon leaves the conical surface of the taper hole of rifle valve pocket 6, so Water under high pressure by the endoporus of rifle valve pocket 6, can just flow through the delivery port of rifle valve pocket 6, then be sprayed by barral of a gun or shower nozzle, with cleaning materials Product.
