Noise check valve refers to a valve that automatically opens and closes the valve disc based on the flow of the medium itself, used to prevent medium backflow. It is also known as a check valve, one-way valve, silencing check valve backflow valve, and backpressure valve. A check valve is an automatic valve that primarily functions to prevent media backflow, prevent pump and drive motor reversal, and discharge container media. Check valves can also be used to supply pipelines to auxiliary systems where the pressure may rise above the system pressure. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).

 

The function of a noise check valve is to prevent flow in the opposite direction and only allow the medium to flow in one direction. Usually, this type of valve operates automatically, and under the pressure of fluid flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the valve seat is cut off by the fluid pressure and the self closing of the valve disc, which acts on the valve seat. It is not suitable for media containing solid particles and high viscosity.

 

 

1. The design is novel and reasonable, the structure is perfect, the weight is light, and the opening and closing are quick.

2. The operating torque is small, the operation is convenient, labor-saving and dexterous.

3. It can be installed in any position and easy to maintain.

4. The seal can be replaced, and the sealing performance is reliable to achieve two-way sealing and zero leakage.

5. The sealing material has the characteristics of aging resistance, weak corrosion resistance and long service life.

 

 

1. The opening and closing is convenient and quick, labor-saving, and the fluid resistance is small, so it can be operated frequently.

2. Simple structure, small size and light weight.

3. It can transport mud, and there is less liquid accumulated at the mouth of the pipeline.

4. Under low pressure, good sealing can be achieved.

5. Good adjustment performance.
