Working principle and characteristics of the stop valve:

The valve plays an important role in the cutting and throttling of the medium in the pipeline in which it is located. The shut-off valve is an extremely important type of shut-off valve. The seal is applied by applying torque to the valve stem, and the valve stem is oriented in the axial direction. The flap exerts pressure so that the disc sealing surface fits snugly against the seat sealing surface, preventing the medium from leaking along the gap between the sealing faces.

The sealing pair of the shut-off valve is composed of a valve sealing surface and a valve seat sealing surface, and the valve stem drives the valve flap to move vertically along the center line of the valve seat. During the opening and closing process of the shut-off valve, the opening height is small, the flow rate is easy to adjust, and the manufacturing and maintenance are convenient, and the pressure is applicable to a wide range.


Advantage

1. Double seal design (corrugated pipe + packing) If the bellows fails, the stem packing will also be avoided;

2. External leakage, and in line with international sealing standards;

3. No fluid loss, reduce energy loss, and improve plant equipment safety;

4. Long service life, reduce the number of maintenance, reduce operating costs;

5. Rugged bellows seal design, to ensure zero leakage of the valve stem, providing maintenance-free conditions.

6. The bellows seal cut-off valve adopts the design of bellows seal, completely eliminating the shortcomings of the normal valve stem packing seal aging and easy to leak, not only improving the energy efficiency, increasing the safety of production equipment, reducing the maintenance cost and frequent Maintenance and maintenance also provides a clean and safe working environment.
