When the tap water used at home is cut off in the pipe network, the water pressure of the tap water pipe network will fluctuate, resulting in the phenomenon of backflow, which will further cause the rotation of the user's water meter, resulting in an error in the count, which is not good for the user or the water company. of. In order to solve this phenomenon, the general practice is to install a check valve in front of the water meter to ensure the accuracy of water measurement. The water meter check valve, as the name suggests, is a valve installed with the water meter to prevent the backflow of water, also known as a one-way valve. Its function is to keep the water in the pipeline flowing in only one direction, preventing backflow. The check valve is an automatic valve, which is opened by the pressure of the fluid itself to open the spring force in the opposite direction from one direction, and the pressure of the fluid in the opposite direction will directly press the valve plate, and the valve closes, preventing backflow. role, that's how it works.
