Introduction of gas stove valve
I. definition of gas stove valve:
The definition of "valve" is the equipment used to control the direction, pressure and flow of fluid in the fluid system. Valve is a device that can make the medium (liquid, gas and powder) in piping and equipment move or stop, and control its flow.
Second, according to the different effects of opening and closing valves, there are many classification methods of valves. Here are the following.
1. Classification by effect and use
(1) Shut off valve: also known as closed-circuit valve, its effect is to connect or cut off the medium in the pipeline. Shut off valves include gate valves, globe valves, plug valves, ball valves, butterfly valves and barriers.
(2) Check valve: also known as one-way valve or check valve, its effect is to prevent the backflow of medium in the pipeline. The bottom valve of water pump suction is also classified as check valve.
(3) Safety valve: the effect of safety valve is to prevent the medium pressure in pipeline or equipment from exceeding the regular value, so as to achieve the purpose of safety protection.
(4) Regulating valve: regulating valve includes regulating valve, throttle valve and pressure reducing valve, and its effect is to regulate parameters such as pressure and flow of medium.
(5) Diverter valve: diverter valves include various distribution valves and traps, which have the effect of distributing, separating or mixing the media in the pipeline.

Working principle of steam safety valve
Working principle of steam safety valveThe structure of steam safety valve mainly includes tension spring type and lever type. Tension spring type means that the seal between the valve disc and the valve seat depends on the force of the tension spring. If the internal steam pressure is highe
