Straight through lift type check valve should be installed in horizontal pipe, vertical lift check valve and bottom valve is usually installed in a vertical pipe on the road, and the bottom-up flow of media.
Swing check valve installation location is not restricted, usually installed in horizontal pipe, but also can be installed in the vertical pipe or dumping pipeline.
When installing check valve, special attention should be paid to the direction of the flow of media, the media should be normal flow direction and the direction of the arrow on the body is consistent, otherwise it will cut off the normal flow of media. Valve should be installed at the bottom of the pump suction pipe.
The check valve closes, will produce water hammer in pipeline pressure, will lead to serious damage to the valve and piping or equipment, especially for the big pipe or high pressure pipeline, it should pay attention to those who use check valve.
Installation notes:
Place the pipe should pay attention to the direction of the direction of the check valve and fluid flow consistent;
Installed in a vertical pipe. For horizontally placed pipes, clamp the check valve vertically;
In the pinch check valve and butterfly valve between the use of a telescopic pipe, do not be directly connected with other valves;
In the operating radius of the valve plate, to avoid adding pipe joints and obstructions;
Not in front of wafer type check valve or after the installation of a tapered tube;
In the vicinity of the elbow to install the check valve, it is necessary to pay attention to keep enough space;
In the pump outlet to install the check valve, at least six times the diameter of the valve space to ensure that the butterfly plate is ultimately affected by fluid.
