I. Overview of NKZ41H vacuum isolation gate valve :

This series of valve connection types are divided into flange and welding. There are two driving modes: manual and electric. 425 550 ,工作介质为水、蒸汽或空气的管路上,作为启闭装置;尤其适用于火电厂汽机冷凝和真空负压系统,起真空隔离密封作用。 This valve is suitable for pipelines with working temperature 425 and 550 , the working medium is water, steam or air.

、设计了真空密封结构填料室,使系统与大气隔离,具有良好的环保性能。 Second, the structural characteristics of NKZ41H vacuum isolation gate valve: 1. Designed a vacuum-sealed structure packing chamber, which isolates the system from the atmosphere and has good environmental performance.
2. Exquisite selection of materials, complying with relevant standards at home and abroad, and high overall quality of materials.
3. The sealing pairing is advanced and reasonable, which improves the sealing performance and has a long service life.
4. The bi-directional elastic sealing of the opening and closing parts adopts parallel gates with small friction, easy opening and closing, convenient maintenance, reliable sealing and excellent performance.
5. The valve stem undergoes quenching and tempering and surface nitriding treatment, and has good corrosion resistance, abrasion resistance and wear resistance.
6. The flange gasket is made of composite material, which has a large expansion coefficient and good air-tightness, ensuring the system is isolated from the atmosphere.
