Embodiment

About the utility model is to reach above-mentioned application target and effect, the technological means that is adopted is enumerated preferable feasible embodiment now, and cooperate graphic shown in, details are as follows:

Embodiment of the present utility model, see also Fig. 3～shown in Figure 5, mainly be to be provided with a valve body 2, one end of described valve body 2 is provided with a perforation 20, the other end at valve body 2 is provided with a knob 21, on the outer wall of valve body 2, be provided with a suction tude 22, be provided with air flue 23 break-through in the described suction tude 22 in valve body 2, on valve body 2, be provided with a gas bleeder valve 3, described gas bleeder valve 3 is to be provided with a valve seat 30 on the outer wall of suction tude 22, the outer wall of described valve seat 30 is provided with outside thread 31, in valve seat 30, be provided with a room 32, be provided with the air flue 23 that a perforation 33 is communicated with in suction tude 22 in the described room 32, one obturating plug 34 is provided in a side of in the room 32 of valve seat 30, one end of described obturating plug 34 is provided with a convex body 340, the other end is provided with an alcove 341, in alcove 341, be provided with a cock body 35, one spring 36 is provided in a side of in the room 32 of valve seat 30, one end of described spring 36 is to be set on the convex body 340 of obturating plug 34, the other end pushes against a valve gap 37, described valve gap 37 is provided in a side of on the valve seat 30, is provided with internal thread 370 in the described valve gap 37, is provided with a bleeder port 371 in the outer end of valve seat 37.

During assembling, see also Fig. 3～shown in Figure 5, at first, cock body 35 is located in the alcove 341 of obturating plug 34, end with spring 36 is set on the convex body 340 of obturating plug 34 again, spring 36 and obturating plug 34 and cock body 35 are inserted in the lump in the room 32 of valve seat 30, again valve gap 37 lids are located on the valve seat 30, the internal thread 370 of valve gap 37 be with the outside thread 31 of valve seat 30 mutually spiral shell establish, the other end of spring 36 then supports the internal face at valve gap 37, and cock body 35 is then pushed room 32 inner faces that are fitted in valve seat 30 by spring 36 elasticity, and 33 sealings of will boring a hole, so, can finish whole assembling.

The full degree that the user can must inflate according to institute, rely on rotation valve gap 37 to adjust the compressing force of spring 36, and then reach the pressure of setting inflation, during use, see also Fig. 5, shown in Figure 6, the perforation 20 of valve body 2 is connected to desires to inflate object (as tire, ball ... Deng) tuyere on (not shown), when pump or air compressor or tire pump ... when inflating the mechanical operation start, air can be sent into valve body 2 inside by connecting tube 4, enter the object inside of desire inflation again by tuyere, when inflation is finished in the object inside of desire inflation, if the user still continues to inflate, its internal pressure can increase thereupon, when internal pressure reaches the pressure that sets, described pressure can push away cock body 35 room 32 inner faces of

valve seat

30,35 of its cock bodys push spring 36, make spring 36 be elastic compression, perforation 33 in the valve seat 30 is then no longer sealed by cock body 35, inner air then can be released by the bleeder port 371 of room 32 through valve gap 37, when internal pressure reduces, 36 on its spring is elastic recovery and cock body 35 is pushed is back to original position, to bore a hole once more 33 the sealing, so, when internal pressure is excessive, then can automatically air be released by the bleeder port 371 of gas bleeder valve 3 described valve gaps 37, can prevent that internal works from damaging because of pressure is excessive, perhaps be inflated object because of excessively inflation explosion damage, can reach best safe handling effect.

The disappointing structure of safety of the present utility model is applicable on the valve body of various different structures, and wherein, another embodiment can be used on the valve 5 with pressing plate 50 structures as shown in Figure 7, can reach the use effect and the purpose of the foregoing description equally.

More than explanation is just illustrative for the utility model, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited, can make many modifications, variation or equivalence, but but all will fall within the claim restricted portion of the present utility model.
