I. Overview of NKJ61H / Y vacuum globe valve :

本真空截止阀按JB/T3595标准设计制造,满足电站设备配套使用要求。 1. This vacuum cut-off valve is designed and manufactured according to JB / T3595 standard, which meets the requirements for supporting the use of power station equipment.

设计了真空密封结构填料室,隔离真空可靠。 2. Designed a vacuum-sealed structured stuffing room to isolate the vacuum reliably.

阀杆经调质及表面氮化处理,有良好的抗腐蚀性,抗擦伤和耐磨性。 3. The valve stem is quenched and tempered and the surface is nitrided to have good corrosion resistance, abrasion resistance and abrasion 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。 4. The flange gasket is made of composite material, with a large expansion coefficient and good air-tightness, which ensures the system is isolated from the atmosphere.

倒密封采用不锈钢螺纹连接密封座或本体堆焊奥氏体不锈钢而成,倒密封可靠。 5. The inverted seal is made of stainless steel threaded connection sealing seat or body surfacing austenitic stainless steel, and the inverted seal is reliable. Packing replacement and maintenance can be performed without downtime, convenient and quick without affecting system operation

Structural features of NKJ61H / Y vacuum globe valve:

真空隔离截止阀主体采用铸锻结构,具有平行双密封副半强制双向密封,密封面到位运动和楔形块楔紧运动分步作用,实现零泄漏。 1. The main body of the vacuum isolation shut-off valve adopts a cast-forged structure, which has a semi-forced two-way seal with parallel double sealing pairs. The sealing surface moves in place and the wedge block moves tightly in steps to achieve zero leakage.

密封面之间摩擦系数小,起闭方便,而且,密封面的磨损有自动补偿功能。 2. The friction coefficient between the sealing surfaces is small, and the opening and closing is convenient, and the wear of the sealing surfaces has an automatic compensation function.

、结构简单,紧凑,检修方便,使用寿命长。 3. Simple structure, compact, convenient maintenance and long service life.

、阀盖填料室设有真空密封机构,具有自胀押金压紧作用,并且,各连接面采用高强膨胀材料密封,使系统与大气隔离,具有很好的真空密封性能。 4. The valve cover packing room is provided with a vacuum sealing mechanism, which has the function of self-expanding deposit and compaction, and each connection surface is sealed with high-strength expansion material to isolate the system from the atmosphere and has a good vacuum sealing performance.

本系列阀门连接形式分为法兰连接、焊接连接两种,驱动方式为手动、电动两种。 5. This series of valve connection types are divided into flange connection and welding connection. The driving methods are manual and electric.

、该系列阀门适用于工作温度 425 550 ,工作介质为水、空气、蒸汽的管路上,作为起闭装置。 6. This series of valve is suitable for the working temperature 425 and 550 , the working medium is water, air, steam pipelines, as a starting and closing device. It is especially suitable for the condensing and vacuum negative pressure systems of steam turbines in thermal power plants, and plays the role of vacuum sealing and isolation.
