Installation requirements for different check valves

by:Sure     2021-08-20
The installation of socket-welded forged steel check valve should pay attention to the following: 1. Do not make the check valve bear weight in the pipeline, and the large check valve should be independently supported so that it is not affected by the pressure generated by the piping system. 2. When installing, pay attention to the direction of medium flow should be consistent with the direction of the arrow voted by the valve body. 3. Lifting vertical flap check valve should be installed on the vertical pipeline. 4. The installation of the lifting type horizontal flap socket welded forged steel check valve should pay attention to the following: 1. Do not allow the check valve to bear the weight in the pipeline, and the large check valve should be independently supported to prevent it from the piping system. The impact of the resulting stress. 2. When installing, pay attention to the direction of medium flow should be consistent with the direction of the arrow voted by the valve body. 3. Lifting vertical flap check valve should be installed on the vertical pipeline. 4. The lift-type horizontal flap check valve should be installed on the horizontal pipeline. Wafer lift check valve should be installed on the horizontal pipeline. The swing check valve can be installed horizontally or vertically. The flap of the swing check valve rotates around the axis of rotation, and its fluid resistance is generally less than that of the lift check valve. It is suitable for larger diameter occasions and the installation position is not restricted. It is usually installed in a horizontal pipeline. It is suitable for Larger caliber occasions. Large-diameter water pipes should be equipped with multi-lobe check valves or large-diameter silent check valves to stagger the closing time of each valve or close slowly to reduce the destructive effect of water hammer.
