Background
Generally be equipped with the cavity that corresponds with the solenoid valve on the gas valve, be used for being connected with the air inlet, switch on or cut through switching on of solenoid valve control gas, the solenoid valve generally triggers through the needle, consequently, need set up the needle mouth that corresponds with the needle on the gas valve, among the prior art, generally set up the sealing washer on the needle mouth, act on the sealing washer through the reset spring on the needle, form the pressure to the sealing washer, thereby guarantee the leakproofness of valve needle mouth, but, when reset spring uses elasticity not enough for a long time, the sealing washer does not have sufficient pressure, lead to the needle mouth to take place gas leakage phenomenon easily.
Therefore, further improvements are needed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of above-mentioned prior art existence, and provide a seal structure of gas valve body, aim at solving one of the above-mentioned technical problem among the prior art to a certain extent at least.
The purpose of the utility model is realized like this:
the utility model provides a seal structure of gas valve body, including the valve main part, the valve main part has air guide chamber and respectively with air inlet and the needle mouth of air guide chamber intercommunication, be equipped with the solenoid valve in the air guide chamber, be equipped with the needle body that is used for triggering solenoid valve work on the needle mouth, be equipped with the jump ring of arranging towards needle mouth direction in proper order on the needle body, flat pad of location and sealing rubber ring, sealing rubber ring and jump ring respectively with the inner wall zonulae occludens of needle mouth, the needle body has the needle cap, be equipped with reset spring between needle cap and the jump ring.
The valve needle body is made of metal copper materials.
The clamp spring is made of stainless steel.
The valve needle opening is provided with a first connecting step and a second connecting step which are arranged from inside to outside, the sealing rubber ring is tightly connected with the inner wall of the first connecting step, and the clamp spring is tightly connected with the inner wall of the second connecting step.
The clamp spring is provided with a connecting part bent towards the needle cap.
The connecting part is a plurality of convex teeth which are uniformly distributed on the clamp spring.
The utility model has the advantages that:
through increasing the jump ring on the valve needle body, the inner wall zonulae occludens of jump ring and needle mouth to form the pressure to sealed rubber ring, even under the not enough condition of reset spring elasticity, still can keep the enough pressure of sealed rubber ring, guarantee the leakproofness of valve needle mouth, avoid valve needle mouth to lead to taking place the gas leakage phenomenon because of reset spring elasticity is not enough, improve the security of gas valve.
Additional aspects and advantages of the invention will be set forth in part in the description which follows, or may be learned by practice of the invention.

Fig. 2 is a schematic structural diagram ii according to an embodiment of the present invention.
Fig. 3 is an enlarged view of embodiment a of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to fig. 1-3, the sealing structure of the gas valve body comprises a valve body 1, the valve body 1 is provided with an air guide cavity 11, an air inlet 12 and a valve needle port 13 which are respectively communicated with the air guide cavity 11, an electromagnetic valve (not shown) is arranged in the air guide cavity 11, the valve needle port 13 is provided with a valve needle body 2 for triggering the electromagnetic valve to work, the valve needle body 2 is provided with a snap spring 3, a positioning flat gasket 4 and a sealing rubber ring 5 which are sequentially arranged towards the direction of the valve needle port 13, the sealing rubber ring 5 and the snap spring 3 are respectively tightly connected with the inner wall of the valve needle port 13, the valve needle body 2 is provided with a needle cap 21, a return spring 6 is arranged between the needle cap 21 and the snap spring 3, the snap spring 3 is additionally arranged on the valve needle body 2, the snap spring 3 is tightly connected with the inner wall of the valve needle port 13, so as to form pressure to the sealing rubber ring 5, even under the condition that the elasticity of the return spring 6 is insufficient, the enough pressure of the sealing rubber ring 5 can be kept, the leakproofness of valve needle mouth 13 is guaranteed, the phenomenon of gas leakage caused by the fact that the elasticity of return spring 6 is insufficient in valve needle mouth 13 is avoided, and the safety of the gas valve is improved.
Further, the valve needle body 2 is made of a metal copper material.
Further, the clamp spring 3 is made of stainless steel, so that the structural strength and the durability of the clamp spring 3 are guaranteed.
Further, be equipped with the first connection step 131 and the second that set up from inside to outside on the needle mouth 13 and connect step 132, the inner wall zonulae occludens of sealed rubber ring 5 and first connection step 131, the inner wall zonulae occludens of jump ring 3 and second connection step 132 makes the connection of sealed rubber ring 5 and jump ring 3 and needle mouth 13 compacter, and the installation is convenient more, accurate.
