ما الأمور التي يجب الانتباه إليها عند استخدام وتركيب صمامات فحص الرقاقة

Wafer check valve is a kind of check valve. Check valve refers to the valve that automatically opens and closes the disc depending on the flow of the medium itself to prevent the medium from flowing back, also known as check valve, one-way valve, reverse flow valve, and back pressure valve. Check valve is a kind of automatic valve, its main function is to prevent the back flow of the medium, prevent the pump and drive motor from reversing, and discharge the container medium. The check valve can also be used to supply the auxiliary system whose pressure may rise above the system pressure.

The wafer check valve is light in weight, small in size, and easy to install between flanges. The inside of the valve is composed of two semicircular springs and a plate surface. The spring is fixed on the valve body with a pin to close the valve plate, and the fluid pressure makes the valve plate close. Its opening spring deforms very quickly, which can protect the pipeline from water hammer damage.　　 　　

Precautions for installation of wafer check valve: 　　 　　

1. When placing the pipeline, pay attention to make the passing direction of the wafer check valve consistent with the flow direction of the fluid; 　　 　　

2. Install in a vertically placed pipeline. For horizontally placed pipelines, place a wafer check valve vertically; 　　 　　

3. Use a telescopic tube between the wafer check valve and the butterfly valve. Never connect it directly with other valves; 　　 　　

4. Avoid adding pipe joints and obstructions within the operating radius of the valve plate; 　　 　　

5. Do not install a reducer in front or behind the wafer check valve; 　　 　

6. When installing a wafer check valve near the elbow, pay attention to leaving enough space; 　　

7. When a wafer check valve is installed at the outlet of the water pump, at least six times the diameter of the valve should flow out to ensure that the butterfly plate is affected by fluid.
