电动执行机构的手轮力与操作时间

Torque of handwheel operation and operation time of electric actuator

电动执行机构是电动阀门的驱动控制部分,电动阀门手动操作力和手动启闭时间也逐渐受到用户的重视。手动操作的功能涉及紧急状态下通过人力操作是否能可靠完成阀门启闭的问题,是保证管道系统与相关设施安全的一个重要方面。以典型执行机构手动操作机构为例,简要介绍了其特点及相关的技术参数。

The electric actuator is the driving control part of electric valve,The torque of handwheel operation and operation timeare also getting more and more attention from users.The function of manual operation involves whether the valve can be reliably opened and closed by manual operation in an emergency,ant it is an important aspect of ensuring the safety of pipeline system and related facilities.This article takes the typical manual operation mechanism of the electric actuator as an example,and briefly introduces its characteristics and related technical parameters.
