Working principle and purpose of the product:
HH44X, HH44T, and HH44H micro resistance slow closing check valves are used in water supply and drainage pipelines. They are installed at the outlet of the water pump to prevent medium backflow and eliminate destructive water hammer. They can effectively reduce the water hammer pressure when the valve is closed, ensuring the safe operation of the pipeline network.
Suitable for pump outlets installed in industrial, agricultural, urban, high-rise residential and other water supply and drainage systems to prevent medium backflow, eliminate water hammer, and protect the safe operation of pumps and pipelines< Product Structure Features:
1. Equipped with a balance hammer device. When the valve disc rotates, the resistance to water flow is small, and the opening force is one-fifth of the original rotation type, making it an energy-saving product< br/>2、 The rear stroke of the valve disc is equipped with a damping device, and the damping time can be adjusted to prevent the occurrence of destructive water hammer< br/>3、 The valve disc has good sealing effect, vibration reduction and wear resistance, and long service life< br/>4、 Smooth operation with low noise.
