Working principle of steam safety valve
The 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 higher than the tension spring pressure, the valve plate will be opened by steam. If the tension spring pressure is higher than the internal steam pressure, the valve plate will be closed automatically and lower than the set pressure to ensure the security of the pipeline or equipment.
Tension spring safety valve is divided into micro open safety valve and full open safety valve. The opening height of the micro open safety valve is 1 / 15 ~ 1 / 20 of the inner diameter of the valve seat, which is a full open safety valve. The lifting safety valve is 1 / 3 to 1 / 4, lever type, which opens and closes the valve by the force of lever and heavy hammer. When the vapor pressure is higher than the force of the heavy hammer, the valve is open, and when the vapor pressure is lower than the force of the heavy hammer, the valve is closed.
