Introduction to cast steel gate valves

The opening and closing parts of the cast steel gate valve are the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. Sealing face has two gate, two of the most commonly used mode gate valve sealing surface form a wedge, the wedge Angle vary with the valve parameters, usually in the form of 50, when the medium temperature is not high for 2 ° 52 '. The wedge gate can be made into a single body, called a rigid gate; Can also be made to produce a small amount of deformation of the gate, in order to improve its technology, to make up for the sealing surface Angle in the processing of the deviation, such a gate is called the elastic gate.
