结合一类进口阀门电动装置的失效分析和新型阀门电动装置的设计 ,讨论阀门电动装置设计中几个值得注意的问题。手动电动切换机构的失效分析和再设计 ,阀门开度设定方式的重新设计 ,阀门开度测量传动方式的改造 ,阀门电动装置速度和力参数的选择。基于上述分析而重新设计的阀门电动装置已成功用于工业生产。所得结论对相关研究具有参考价值。 Combined with the failure analysis of a class of imported valve electric devices and the design of new type valve electric devices, several notable problems in the design of valve electric devices are discussed. Failure analysis and redesign of manual electric switching mechanism, redesign of valve opening setting mode, transformation of valve opening measurement transmission mode, selection of valve electric device speed and force parameter. Valve actuators based on the above analysis have been successfully redesigned for industrial production. The conclusion is of reference value to related research.
