大口径真空插板阀优化设计

Optimal Design of Large Caliber Vacuun Gate Valve

伴随我国航天及国防事业的巨大进步,更多关键和特殊的装备需要在真空环境下生产或试验,大型和特大型地面模拟设备开始研制和投入使用,对关键部件真空插板阀的要求也越来越高。由于真空插板阀的口径不断增大,传统结构的真空插板阀无法满足要求,为此针对大口径真空插板阀在使用过程中发现的问题,对大口径真空插板阀采取了阀体分体结构设计、独立运行轨道设计、自动超压保护装置设置、传动系统增设离合器、密封结构形式改进等优化设计,有效地解决了传统真空插板阀结构、控制等方面存在的弊端。通过优化设计制造的大口径真空插板阀已投入运行,阀门运行稳定可靠。该设计方法可以有效解决未来更大口径真空插板阀的设计难题。

With the great progress of China′s aerospace and national defense industry,more and more key and special equipments need to be produced and tested in vacuum environment.Large simulation equipment began to be developed and put into use,and the requirements for vacuum gate valves,the key components,are becoming higher and higher.Due to vacuum flashboard valve diameter increasing,the structure of the traditional vacuum flashboard valve can′t meet the requirements,in view of the large diameter for this vacuum flashboard valve is the problem in use process,and the large diameter vacuum flashboard valve adopted fission body structure design,independent orbit design,automatic overpressure protection settings,add clutch transmission system,seal structure improvement and optimization,effectively solve the traditional vacuum flashboard valve structure,the insufficiency of control,etc.The open-mouth vacuum gate valve manufactured by optimized design has been put into operation,and the operation is stable and reliable.This design method can effectively solve the design problem of larger diameter vacuum gate valve in the future.
