Classification of the safety valve

Valve structure are two major categories: spring-loaded and leveraged. Spring means sealing valve and valve seat by spring force. Leveraged rely on leverage and weight forces. With the large capacity needs, harboring a pulse valve, also known as the patio heater control valve, the main valve and the auxiliary valve. When the pipeline medium pressure exceeds a predetermined pressure value, the auxiliary valve to open, the media along the catheter into the main gas stove safety valve and the main valve is opened to reduce the media pressure increased. Emissions safety valve depends on the caliber of the valve seat and valve opening height, it can be divided into two types: Weiqi opening height is the seat diameter (1/20) - (1/40), the entire Kai It is (1/3) - (1/4).
In addition, with different requirements, there are enclosed and non-enclosed. Enclosed discharge medium that is not compromised, the entire exhaust outlet along a predetermined, generally used for toxic and corrosive media. Enclosed is generally not used for toxic or corrosive media.
