How to install the check valve

Check valve refers to the opening and closing parts for the circular disc and rely on its own weight and medium pressure to produce action to block the media flow back a valve.Automatic valve type, also known as check valve, check valve, backflow valve or isolation valve.Check valves are often used in overwater or flue gas piping.Do you know how the check valve is installed?

How to install the check valve?First of all, it should be clear that a check valve is a one-way valve and should be installed in accordance with the direction of the arrow on the valve body, which points in the direction of the flow in the pipe.

First look at both ends of the check valve and find the end where the water enters the check valve, usually below the check valve.Connect the inlet to the outlet of the pipe.Water flows from the inlet port into the check valve and the check valve begins to operate.

A little bit up on one end is the drain port, and this is where the water flows out.If the pressure of water flow into the check valve reaches a certain value, the check valve plate will be opened and the outlet end will have water flow out. When the flow of water is interrupted, the check valve plate will be closed by its own force to prevent water backflow, so as to check whether the check valve has been installed successfully.
