Flexible Wedge Gate Valve

Wedge resilient gate valve gate is a single piece type, two sealing surfaces are supported on the center of the cantilever. Its vertical center surface with an annular groove, it is this groove so that the gate has a certain degree of elasticity, when the valve is closed, the use of the gate generated by the deformation of a small amount to make up for the processing and manufacturing deviations and the seat of the gap, so that the two sealing surfaces of the gate and the two sides of the valve seat to achieve a complete fit, while the formation of the sealing pressure, so as to achieve sealing. When the elastic gate is closed, it is by the elastic load of the gate applied to the sealing surface of the valve seat instead of the wedge force directly applied by the valve stem. No matter the thermal expansion and contraction caused by temperature change, or the contraction stress generated by the deformation of the valve body will not lead to the wedging of the gate.
