How to install the check valve
The check valve is an important valve in the process of water transportation, and it is an important part that can effectively prevent the backflow of water. How should the check valve be installed?
1. How to install the check valve？
First observe the two ends of the check valve and find the water inlet port of the check valve, which is generally at the lower part of the check valve. Connect this water inlet port to the outlet of the water pipe. Under normal circumstances, water flows into the check valve from the inlet port first, and then the check valve starts to work.
The upper part of the other end is the water flow out port, which is the position where the water flows out. If the pressure of water flowing into the check valve reaches a certain value, the valve of the check valve will open, and water will flow out from the outlet, otherwise it will flow backwards, the valve of the check valve will be closed, and no water will flow out of the valve. , to check whether the check valve is installed successfully.
2. Precautions for installation of check valve？
a. Although the check valve controls the valve by judging the water flow through the pressure, it prevents the backflow of the water. But it also has a certain pressure limit, and it cannot be placed in a system with particularly high pressure. If the pressure is too high, it is easy to cause damage to the check valve, and the check valve will not work normally, and it will not play its role.
b. Generally, there will be corresponding marks on the check valve. If you are not sure how to install it, use the direction of water flow as the standard and install it in the same direction as the mark on the check valve body.
c. Be careful not to put some heavy objects on the check valve, which will easily damage the check valve and affect its judgment of water flow pressure.
d. When installing the check valve, pay attention to the tightness of the check valve. If the sealing of the check valve is not enough, the pressure judgment of the check valve on the water flow will be inaccurate, and the check valve will not work.
