The wafer check valve installation considerations, have to clear

The wafer check valve is a universal one-way flow valves. Its light weight, small size, easy installation between the flange, valve inside is composed of two semicircle spring and the plate, with the spring pins, the body deformation to close the valve plate, fluid pressure and its open spring deformation soon, so that can protect the pipes from water hammer damage. Laying the pipeline installation considerations: 1, make the wafer check valves should be paid attention to by the direction consistent with the direction of flow; 2, installation in the line of vertically. For horizontal pipe, vertically wafer check valves; 3, between the wafer check valve and butterfly valve using a telescopic tube, don't directly connected with the other valves; 4, the valve plate within a radius of operation, to avoid joining pipe joint and obstruction; 5, not behind or in front of the wafer check valve installed a variable diameter tube; 6, near the bend the wafer check valve installation, pay attention to have enough space; 7, install the wafer check valve in the pump export, at least six times outflow valve diameter of space in order to make sure the butterfly plate by fluid effect finally.
