Introduction of gas safety valve

The lever type safety valve mainly relies on the force of the lever hammer to work, but the large size of the lever type safety valve often limits the selection range. When the temperature is high, choose a safety valve with a radiator. The main parameter of the gas safety valve is the displacement, which is determined by the diameter of the valve seat and the opening height of the valve disc. The micro-opening type means that the opening height of the valve disc is 1/40~l/20 of the throat diameter of the valve seat. Full lift means that the opening height of the disc is 1/4 of the throat diameter of the valve seat.
