The paper analyzes and discusses the working principle,operation method and forces acted on the valve,failure cause of the automatic recirculation valve installed in the main feedwater pump for Qinshan Nuclear Power Plant.Based on this analysis,the improve ment of mator-driven stop valve in by-pass pipe instead of original valve is given.

对秦山核电站主给水泵上的自动再循环阀的工作原理、动作方式、受力情况及其失效机理等进行了剖析与探讨。在此基础上,提出了该阀的改进措施,介绍了在旁通管上增加电动截止阀代替自动再循环阀的工艺结构。

When nuclear power plants operate, valves are one of the devices which easily cause an accident. In order to guarantee the safety of nuclear power plants, reliable valves must be chosen. There are more than 10 varieties, over 300 in quantity of helium valve included in the 10MW high temperature helium cooled test reactor (HTR 10). They are mainly globe valve, check valve, pressure relief valve, etc. These valves are not only widely used as pressure resistant devices, but also connected a large number of...

When nuclear power plants operate, valves are one of the devices which easily cause an accident. In order to guarantee the safety of nuclear power plants, reliable valves must be chosen. There are more than 10 varieties, over 300 in quantity of helium valve included in the 10MW high temperature helium cooled test reactor (HTR 10). They are mainly globe valve, check valve, pressure relief valve, etc. These valves are not only widely used as pressure resistant devices, but also connected a large number of systems in HTR 10. So they play an important role in ensuring normal operation and shut down in safety of HTR 10. The present paper gives the design requirements of helium valves in HTR 10 as well as introduces the manufacture, quality ensured, inspection and test of nuclear class helium valves in HTR 10.

核电站运行时,阀门是最易发生事故的设备之一。为了确保核电站的安全,必须选用安全可靠的阀门。10MW高温气冷实验堆(HTR-10)中的氦气阀门有十多个品种、300多台,主要为截止阀、调节阀、止回阀、安全阀等。这些阀门是高温气冷堆中面广量大的承压设备,它们连接着高温气冷堆中众多的系统,对于保证高温堆的正常稳定运行及安全停堆起着重要的作用。该文介绍了HTR-10氦气阀门的概况,氦气阀门的要求、核级氦气阀门的设计、制造、质量保证、检验和出厂试验。

The harmonic screw type valve is driven by the double wave harmonic screw. It can transform circle movement to line movement for the closing and opening of the valve. The body and flange are airproofed by shell. The stern guiding device is used in the stop valve for guide. Radial distortion of the flexible component in the stop valve can be adjusted so as to ensure the joint depth between flexible screw thread trepanning circular groove and screw thread on the screw. Both flexible whorl cover and stern with...

The harmonic screw type valve is driven by the double wave harmonic screw. It can transform circle movement to line movement for the closing and opening of the valve. The body and flange are airproofed by shell. The stern guiding device is used in the stop valve for guide. Radial distortion of the flexible component in the stop valve can be adjusted so as to ensure the joint depth between flexible screw thread trepanning circular groove and screw thread on the screw. Both flexible whorl cover and stern with screw are placed in flexible sealing shell. Flexible rolling bearing is composed of an outer ring and an inter ring. There is a raceway groove on the surface of the outer ring and the inter ring. The rolling elements in the groove are separated by cage, and the screw and stern are fixed by pin.

谐波螺旋式阀门采用双波谐波螺旋传动,实现由圆周运动向直线运动的转化,实现阀门的启闭。阀体与连接法兰的密封为体盖密封。在该截止阀的设计中,采用了阀杆导向装置,达到导向的目的。截止阀的柔性元件的径向变形值可以调节,保证柔性螺纹套的环槽与螺杆上的螺纹的接合深度。柔性螺纹套和带有螺杆的阀杆均置于柔性密闭壳体中。柔性轴承由薄壁的外座圈和内座圈组成,内外座圈的端面有环状轨道,其中置有用保持架隔开的滚动体,另外在螺杆与阀杆相互位置的固定设计时,采用了销联接。
