Installation location:
It should be as close as possible to the equipment or pipe section that needs to be prevented from backflow. Avoid installing in places where sediment may accumulate to avoid affecting the action of the valve disc.
Correct direction:
Make sure that the installation direction of the check valve is consistent with the flow direction of the fluid, otherwise it will not play a check function.
Horizontal or vertical installation:
According to the type of check valve, install it in accordance with the prescribed installation method. For example, the lift check valve should generally be installed vertically. The swing check valve can be installed horizontally or vertically, but when installed on a vertical pipe, the fluid should flow from bottom to top.
Firm connection:
Ensure that the connection with the pipeline is tight to prevent leakage.
Clean the pipeline:
Before installation, impurities, welding slag, etc. in the pipeline should be cleaned to avoid damaging the valve disc or affecting the normal operation of the valve.
Avoid additional stress:
Avoid applying inappropriate external force to the check valve during installation to avoid deformation or damage.
Convenient operation and maintenance:
The installation location should be convenient for future operation and maintenance.
Consider temperature and pressure:
Select the appropriate material and specification of the check valve according to the operating temperature and pressure of the system to ensure that it can work properly.
Supporting facilities:
If necessary, corresponding filters, cut-off valves and other supporting facilities should be installed at the same time to ensure the stable operation of the system.
