真空隔离闸阀 概述: I. Overview of NKZ41H vacuum isolation gate valve :  

连接形式分法兰、焊接两种,驱动方式有手动、电动两种。 NK vacuum isolation valve series connection type is divided into flange, welding two, driving methods are manual, electric two. 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.

真空隔离闸阀 结构特点 Structural features of NKZ41H vacuum isolation gate valve

1. A vacuum-sealed structured packing chamber is designed to isolate the system from the atmosphere and has good environmental performance.
、选材考究,符全国内外相关标准,材料的全面质量高。 2. Exquisite selection of materials, complying with relevant standards at home and abroad, and high overall quality of materials.
、密封副配对先进合理,提高了密封性能,使用寿命长。 3. The sealing pairing is advanced and reasonable, which improves the sealing performance and has a long service life.
、启闭件采用平行闸板双向弹性密封,摩擦力小,启闭轻松,维修方便,密封可靠,性能优良。 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.
、阀杆经调质及表面氮化处理,有良好的抗腐蚀性、抗擦伤性和耐磨性。 5. The valve stem undergoes quenching and tempering and surface nitriding treatment, and has good corrosion resistance, abrasion resistance and wear resistance.
、法兰垫片采用复合材料,膨胀系数大、气密性能好、保证系统与大气隔离可靠。 6. The flange gasket is made of composite material, which has a large expansion coefficient and good air-tightness, ensuring the system is reliable and isolated from the atmosphere.
