摘要
根据阀门电动装置基本原理 ,分析了手动操作产生过扭矩的原因和带来的危害。通过与电动操作比较 ,提出了手动操作过扭矩的非定量性质 ,同时给出解决这一问题的办法。
According to the principles of electric valve actuators, the reason and harm of operation by hand to exceed the torque limit are analyzed. It is pointed that indeterminable character of hand operating torque by comparison with electric operation. An improvement method is given.
