HH44XProduct Introduction of Micro Resistance Slow Closing Check Valve

Micro resistance slow closing check valve is used on water supply and drainage pipelines, installed at the outlet of the water pump, to prevent medium backflow and eliminate destructive water hammer, and can effectively reduce the pressure of water hammer when the valve is closed, ensuring the safe and reliable operation of the pipeline network.

It has a light valve disc, large opening, good power saving, low fluid resistance, novel design of water hammer elimination mechanism, stable and reliable sealing performance, wear resistance, and long service life.

HH44XMicro resistance slow closing check valveFeatures and advantages:

Equipped with a balance hammer device. When the valve disc is rotated, the resistance to water flow is small, and the opening force is only one-fifth of the original rotation type, making it an energy-saving product.

The rear stroke of the valve disc is equipped with a damping device, and the damping time is adjustable to prevent the occurrence of destructive water hammer.

Novel rubber coated valve disc design, reliable sealing, corrosion resistance, vibration reduction and wear resistance, long service life; Smooth operation with low noise.

HH44XProduct Introduction of Micro Resistance Slow Closing Check Valve

Micro resistance slow closing check valve is also a one-way valve, a type of check valve, which is an intelligent valve that prevents medium backflow, water hammer, and water hammer phenomena. Micro resistance slow closing check valves are mainly used in pipelines of water supply and drainage systems, installed at the outlet of water pumps to prevent medium backflow and eliminate water hammer, and can effectively reduce the pressure of water hammer when the valve is closed, ensuring the safe operation of the pipeline network.

HH44XConnection size of micro resistance slow closing check valve

HH44XThe micro resistance slow closing check valve is mainly composed of valve body, valve cover, valve disc shaft assembly, piston assembly, isolation device, one-way valve, micro regulating valve and other components. Its working principle relies on the flow velocity and head of the inlet medium, and the valve disc automatically opens to allow the medium to pass through. The pressure water inside the valve body flows into the rear chamber of the piston assembly through a micro valve, pushing the piston out of the piston chamber. When the water flow stops(Or when the water pump suddenly stops running)Due to the self weight of the valve disc and the effect of water backflow, the valve disc automatically closes. However, due to the piston being in the pushed out position and pressing against the valve disc, the valve disc cannot fully close the valve port and there is still room for improvement20%The opening allows water flow to pass through, which reduces the water hammer pressure. When the valve disc is pressed against the end of the piston, due to the generation of reaction force, the water in the rear chamber of the piston prevents the piston from exiting and also prevents the valve disc from closing. At this time, the valve disc can only be slowly closed by slowly adjusting the valve to flow back to the isolation device. The valve disc is divided into two steps of fast and slow closure to achieve the effect of preventing reverse flow and reducing water hammer. The length of piston extension determines the degree of gradual closure of the valve disc. The slow closing degree is large, the water hammer is small, and the closing time is extended; On the contrary, a small opening can cause destructive water hammer. Therefore, the valve adopts a slow closing opening regulator in its structure, which controls the length of the piston extension with a pull rod. The length of the pipeline determines the period of the peak water hammer. In order to meet the requirements of the slow closing time of various systems, this valve is equipped with a micro regulating valve, which can accurately control the flow rate of compressed water in the rear chamber of the piston according to the duration of the peak water hammer, that is, to control the slow closing time of the valve disc. The closing time is determined by0～60sAdjust arbitrarily.
