Description

Arbitrary rotation type connecting device of pneumatic valve

Technical Field

The invention relates to a gas connecting device, in particular to a rotary type gas pipe connecting device of a pressure reducing valve.

Background

With the improvement of life of people, outdoor barbecue activities are more. Barbecue oven can be used to some in open air barbecue, and for the environmental protection, some barbecue ovens burn natural gas, therefore the barbecue oven need connect the gas bottle air feed.

And the gas bottle and the gas pipe of the barbecue oven need to be connected together through a connector, so that gas can be supplied.

General connector includes joint one and connects two, and joint one all communicates with connecting pipe fixed connection with the relief pressure valve, and connects two and the trachea on the oven to be connected, thereby joint one and connect two to put through oven and gas bottle through screw thread fixed connection together, then the relief pressure valve is connected fixedly with the gas bottle, among the above-mentioned structure, when joint one with connect two to be connected fixed back, the angle of relief pressure valve can not adjust, therefore bring the use inconvenience for the user. The application has designed a gas pipe connection device of relief pressure valve free rotation angle regulation to above-mentioned problem.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides an arbitrary rotary connecting device for an air valve.

The technical scheme adopted by the invention for solving the technical problems is as follows:

the utility model provides an arbitrary rotation type connecting device of pneumatic valve which characterized in that: including sleeve, connecting pipe, valve body and joint, the valve body sets up in the sleeve, be equipped with the limit structure that the restriction valve body deviates from the sleeve between sleeve and valve body, be equipped with gas pocket one in the valve body and can seal the case subassembly of gas pocket one, the connecting pipe is fixed with the valve body and just communicates with gas pocket one, be equipped with gas pocket two in the joint, connect and sleeve threaded connection and can insert simultaneously in the gas pocket one and extrude the valve core subassembly and make gas pocket one and gas pocket two communicate, be equipped with seal groove one on the inner wall of gas pocket one and set up the sealing washer one in seal groove one, connect and the sealed cooperation of sealing washer one.

Threaded connection include the internal thread that the sleeve inner wall was equipped with and connect the external wall to be equipped with interior screw-thread fit's external screw thread.

The inner wall of the first air hole is provided with a convex ring, the valve core assembly comprises a valve core and a spring capable of pushing the valve core to reset, the valve core is arranged in a central hole of the convex ring, a second sealing ring is arranged on the valve core, and the valve core can enable the second sealing ring and the convex ring to extrude to seal the central hole under the pushing of the spring.

And a second sealing groove is formed in the valve core, and the second sealing ring is sleeved in the second sealing groove.

The tail end of the valve core is provided with a core rod, and one end of the spring is sleeved on the core rod.

The limiting structure comprises a first limiting step arranged in the sleeve and a second limiting step arranged on the surface of the valve body, and the first limiting step can be abutted against the second limiting step to prevent the valve body from being separated from the sleeve.

The beneficial effects of the invention are: this device inserts among the gas pocket one through the joint and extrudes valve element group spare and makes gas pocket one and gas pocket two intercommunications have and can guarantee normally to ventilate, and the back of connecting with the valve body separation, and the valve element group spare can seal gas pocket one to guarantee that the gas bottle is airtight, above-mentioned structure is not only connected conveniently, can realize connecting moreover and ventilate, unpacks apart the effect of disconnected gas, has guaranteed user's safety.

And the valve body of this application is the activity sets up in the sleeve, therefore can the free rotation, and when sleeve and joint threaded connection, we guarantee sleeve and joint connection back through the length that sets up threaded connection part, the sleeve can not extrude the valve body and die the valve body lock, thereby the valve body also can the free rotation after sleeve and joint threaded connection, certainly make the valve body also can not deviate from the sleeve through limit structure, thereby also can the free rotation with valve body fixed connection's connecting pipe, thereby also can the free rotation angle regulation with the relief pressure valve that the connecting pipe is fixed of course, and because sealing washer one is sealed fit with the joint, therefore certain frictional resistance has between the two, not only the gas tightness has been guaranteed, and can guarantee to keep this angle after the valve body rotates, thereby make the relief pressure valve can keep at this angle.
