Power Plant Steam Flange Vacuum Globe Valve
Power Plant Steam Flange Vacuum Globe Valve adopts a cast-forging structure, and has a parallel double-sealed pair and a half-forced two-way seal, and the sealing surface in-position movement and the wedge-shaped wedge wedge movement are step-by-step action to realize zero leakage.
Furthermore, the friction coefficient between the sealing surfaces is small and the opening and closing are convenient. Moreover, the wear of the sealing surface has an automatic compensation function.
1. According to the JB/T3595 standard, which meets the requirements for supporting the use of power station equipment.
2.The valve stem is Temper and Nitrid on the surface to provide good corrosion resistance, scratch resistance and wear resistance.
3.Also, it has a large expansion coefficient and good airtight performance, ensuring the system and the atmosphere are isolate and reliable.
4.As well as, the structure is simple, compact, easy to repair and long service life.
5.The bonnet filling chamber is provided with a vacuum sealing structure, which has a self-expanding and compacting effect, and the sealing is sealed with a high-strength expansion material, so that the system is completely isolated from the atmosphere, and has a good system tightness.
