Gas valve high in safety

Abstract

The invention discloses a gas valve high in safety. The gas valve comprises a valve body, a gas inlet and a gas outlet, wherein the gas inlet is formed in one side of the valve body; the gas outlet is formed in the other side of the valve body; a rotary rod penetrates through the top of the valve body; one end of the rotary rod extends outside the valve body; the exposed end of the rotary rod is fixedly connected with a rotary disc; pressure boards are in threaded connection with the two sides of the rotary rod and located in an inner cavity of the valve body; pressure board sliding grooves are fixedly formed in the two sides of the inner wall of the valve body; and the pressure boards and the pressure board sliding grooves are in sliding connection. According to the gas valve high in safety, as a safety valve and a check valve are adopted, when danger occurs, a gas source is cut off automatically, and the safety of a user is ensured; a spring telescopic rod is additionally arranged, the situation that sealing is not tight as a valve is used for a long time is effectively avoided, and the gas sealing tightness effect is achieved; and the inner cavity structure of the valve body is improved, so that the effect that the rotary disc rotates in situ is achieved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a gas valve with high safety. Background technique [0002] Valves are mechanical devices that control the flow, flow direction, pressure, temperature, etc. of flowing fluid media. Valves are basic components in piping systems. Valve fittings are technically the same as pumps, and are often discussed as a separate category. Valves can be manually Or handwheel, handle or pedal operation, can also be controlled to change the pressure, temperature and flow of the fluid medium, the valve can perform continuous or repeated operations on these changes, such as safety valves installed in hot water systems or steam boilers, The existing gas valve cannot guarantee the safety of users, especially the liquefied gas valve body, which cannot cut off the gas source when the gas leaks. The existing gas valve is used for a long time, and the wear is serious, which eventually leads to gas leakage,...

Valves can be manually Or handwheel, handle or pedal operation, can also be controlled to change the pressure, temperature and flow of the fluid medium, the valve can perform continuous or repeated operations on these changes, such as safety valves installed in hot water systems or steam boilers, The existing gas valve cannot guarantee the safety of users, especially the liquefied gas valve body, which cannot cut off the gas source when the gas leaks. The existing gas valve is used for a long time, and the wear is serious, which eventually leads to gas leakage, which is very harmful. The valve stem of the existing gas valve has a large telescopic distance, which takes up a lot of space
