A gas valve with high safety

Abstract

The invention discloses a gas valve with high safety, comprising a valve body, an air inlet and an air outlet, one side of the valve body is provided with an air inlet, and the other side of the valve body is provided with an air outlet, A rotating rod runs through the top of the valve body, and one end of the rotating rod extends to the outside of the valve body, the exposed end of the rotating rod is fixedly connected with a rotating disk, and the two sides of the rotating rod are located inside the valve body. A pressure plate is threadedly connected with the cavity, and a pressure plate chute is fixed on both sides of the inner wall of the valve, and the pressure plate is slidably connected with the pressure plate chute. The gas valve with high safety adopts safety valve and check valve. When danger occurs, the gas source is automatically cut off to ensure the safety of users. By adding a spring telescopic rod, it can effectively avoid the long-term use of the valve. The result is that the sealing is not tight, and the effect of tight gas sealing 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
