The correct installation method for a check valve includes the following steps and precautions:
Installation location and direction: Check valves are usually installed at the water outlet, ensuring that the water flow direction is consistent with the direction of the arrow marked on the check valve. The inlet port of the check valve is usually located at a lower position, while the outlet port is located at a higher position, which can effectively prevent water backflow.
Pre-installation inspection: Before installation, carefully check the appearance and Brand of the check valve to ensure that it complies with relevant national standards. Conduct strength and sealing tests to confirm its qualification before installation.
Installation steps: First, observe both ends of the check valve to locate the inlet port, and then connect the inlet port to the water pipe's outlet port. The check valve starts operating when water flows into the inlet port. Ensure that the connection is tight and secure.
Type selection: Select the appropriate check valve type according to the actual situation. Lift check valves are suitable for small-diameter pipes with large head loss; swing check valves are suitable for large-diameter pipes and can be installed on horizontal and vertical pipes, but the water flow direction must be maintained from bottom to top.
Check if the installation is correct: The correct installation of the check valve can be checked by observing the water flow phenomenon. When the water pressure exceeds a certain value, the valve opens automatically; when the water pressure is below a certain value, the valve automatically closes to prevent water backflow.
By following the above steps and precautions, the correct installation and use of the check valve can be ensured.
