High Sealing Flange Globe Valve Reduce Energy Loss CE / ISO9001 Approved
The valve plays an important role in cutting off and throttling the medium in the pipeline where it is located. As a very important shut-off valve, the valve is sealed by applying torque to the valve stem. The valve disc exerts pressure to make the valve disc sealing surface and the valve seat sealing surface closely fit to prevent the medium from leaking along the gap between the sealing surfaces.
The sealing pair of the stop valve is composed of a valve disc sealing surface and a valve seat sealing surface. The valve stem drives the valve disc 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 in a wide range.
Compared with the other commonly used shut-off valves in industrial production, one by one, the stop valve is simpler in structure than the former, which is easier to manufacture and maintain. In terms of service life, the sealing surface of the shut-off valve is not easy to wear and abrasion, and there is no relative sliding between the valve disc and the seat sealing surface during the valve opening and closing process, so the wear and abrasion on the sealing surface is less, so the seal is improved. The service life of the pair of shut-off valves in the fully closed process is small, and the height of the valve is smaller than that of the valve. The disadvantage of the globe valve is that the opening and closing torque is large and it is difficult to achieve rapid opening and closing. Because the flow passage in the valve is relatively tortuous, the fluid flow resistance is large, resulting in a large loss of fluid power in the pipeline.
Structural characteristics of stainless steel globe valve:
1. Advanced structure, reliable seal, excellent performance and beautiful appearance. The rigidity of the valve stem is increased, the noise and vibration are significantly reduced, and the service life and performance of the valve are improved.
2. The stop valve can be installed in any position of the pipeline, and the medium flows from the bottom to the top.
3. Above DN250 adopts advanced multiple seals, double brackets, guided movement (which can greatly improve the resistance to water hammer), and the medium enters from above. The stuffing room runs out, which effectively improves the valve's various performance and application range. ("Close" torque is 10% of the ordinary valve "Open" torque is 3% of the ordinary valve).
4. The stainless steel globe valve is suitable for pipes of various corrosive media, and has good corrosion resistance and sufficient strength.
5. Alloy steel globe valve is suitable for high temperature resistant steam and oil pipelines, and has high temperature resistant characteristics.
