SAFETY VALVE

DESCRIPTION AND FEATURES

Safety Valve refers to a kind of safety valve with relatively small opening height and discharge capacity of valve disc. The sealing surface of the valve disc has two types: flat surface and conical surface. Their discharge area is calculated according to the area of the cylindrical surface or conical surface formed between the valve disc and the valve seat. The utility model has the advantages of simple structure and convenient manufacture, maintenance, test and adjustment. It is suitable for occasions with small discharge capacity, large back pressure and stable system pressure
