Different check valve installation instructions
Published Time：2013-11-29
First, socket weld forged steel check valve installation should note the following top:
1, the check valve in the pipeline do not bear the weight of so large a check valve should be independent of the support, so that the impact of unmanaged system pressure.
2, note the direction of media flow should be consistent with the direction of the arrow on the body when installing ticket.
3, the vertical lift valve check valve should be installed on a vertical pipe.
4, the level of valve lift check valve should be installed in horizontal pipelines.
Second, Wafer lift check valves should be installed on the pipe horizontal direction.
Third, swing check valve can be installed horizontally or vertically. Swing check valve around the shaft rotates, the fluid resistance is generally less than lift check valve, which applies to the larger diameter of the occasion, the installation location is not restricted, usually installed in horizontal piping, it applies with larger diameter occasions.
Fourth, should be a check valve or large-caliber Orange Peel silent check valve on the large-diameter pipes, so that each valve closing time or slow stagger off to reduce the damaging effects of water hammer.
