摘要
介绍了真空热处理技术的优点,总结了双室真空气淬炉中附件"闸阀"的制造经验,阐述了闸阀的密封工作原理、作用、传动以及关键部件(阀体、连杆机构、阀板)的加工制造工艺,同时对连杆机构做了详细的受力分析,并指出"闸阀"制造过程工艺控制的重要性,只有严格控制加工工艺流程才能保证"闸阀"的制造精度,从而满足整台设备的技术参数。
Introduces briefly the advantages of vacuum heat-treatments. Describes the experience in making of brake-valves. for double-room vacuum gas quenching furnace especially the working principle of its sealings, function transmission and the technological processes of its key components （valve body, linkage and valve plate）, with a force analysis made to the linkage in detail. The process flow should be controlled strictly to ensure the precision of brake-valve so as to satisfy the technological parameters required entirely for the assembly.
