PPR check valves are usually installed on the connecting pipe between the water source and the water device. To ensure a one-way flow of water. Prevent damage to pipes and equipment caused by water hammer or water pressure fluctuations caused by water backflow. The following are the specific requirements for PPR check valve installation position:
Close to pump outlet
In water supply systems, PPR check valves are usually installed on the outlet line of the pump. This ensures that when the pump is working properly, the check valve can be quickly closed to prevent water backflow.
Outlet pipe height
In the water supply system, the outlet pipe of the PPR check valve should be higher than the inlet pipe of the pump. This ensures that when the pump stops, the check valve automatically closes to prevent water backflow.
Outlet pipe low
In the drainage system, the outlet pipe of the PPR check valve should be lower than the height of the water equipment. This ensures that the check valve opens automatically when the equipment is in use, allowing the flow of water to flow smoothly.
Outlet pipe straight
When installing the PPR check valve, ensure that its outlet pipe is as straight as possible. Avoid excessive elbow or pipe bending to reduce fluid resistance.
Direction of attention
When installing the PPR check valve, note that the direction of the arrow is consistent with the direction of the water flow. To ensure the normal operation of the check valve.
Consider maintenance space
When installing the PPR check valve, consider leaving sufficient service space. For future maintenance and maintenance of the valve.
Pipe load consideration
For large water supply systems or high-rise building water supply systems, the bearing problem of the pipeline should be considered. Reasonably select the installation position and support structure of the check valve. To prevent pipe deformation or rupture.
In short, the installation position of the PPR check valve should be selected according to the actual demand and the parameters of the pipeline system. To ensure its normal work and extend the service life. Chuangrong During the installation process, attention should be paid to compliance with relevant standards and specifications. Follow the correct installation method for construction.
