DYH41X quick closing check valve

DYH41X quick closing check valve overview: The quick-closing check valve is mainly composed of body, valve seat, valve stem, spring, valve clack, guide sleeve and other parts. When the pump is turned on, the valve flap rises under the thrust of the water bottom to open the valve, and the spring is quickly closed under the action of the spring force. When the water flow is close to 0, the valve flap is completely closed. The phenomenon of no water backflow, and at the same time, because the water cannot flow back, no kinetic energy is generated, and the occurrence of water hammer is prevented.

DYH41X quick closing check valve

Technical performance characteristics of DYH41X quick closing check valve
1. The main valve body adopts a Y-type diaphragm structure, and the sealing pair is a non-metallic seal; the valve generally requires horizontal installation, and the connection with the pipeline is a flange connection. The flange connection size is implemented in accordance with the national standard GB/T17241.6.
2. Composed of main parts such as valve body, valve cover, central shaft, copper sleeve, valve seat, valve clack, etc., realized by controlling the up and down movement of the valve clack.
3. It has the characteristics of hydraulic automatic control and can be interlocked with the water pump. When the water pump stops, it can quickly check back to prevent water hammer.
4. The sealing effect is good, and the leakage of the valve is guaranteed to be zero leakage.
5. The valve body adopts Y-shaped streamlined structure with reasonable structure.
6. The valve can be maintained online.
7. The casting adopts advanced casting technology and should have a good surface painting. The painting method is baking paint, and the paint color is determined by the buyer.
