良工阀门阀门其运动过程可以由行程、扭矩或轴向推力控制。由于执行器的工作特性和利用率取决于管道或设备上良工阀门阀门的类型、设备的工作规范和位置。所以，掌握执行机构的正确选择，考虑到防止过载(工作扭矩高于控制扭矩)的发生是关重要的。操作力矩是选择执行器的主要参数。电气设备的输出力矩应该是良工阀门阀门操作力矩的1.2~1.5倍。执行器的主机结构有两种，一种是不配置推力板，此时直接输出扭矩；另一种是配置推力板。此时，输出扭矩通过推力板中的阀杆螺母转换为输出推力。
The movement process of Lianggong valve can be controlled by stroke, torque, or axial thrust. Due to the working characteristics and utilization rate of the actuator depending on the type of valve on the pipeline or equipment, the working specifications and position of the equipment. Therefore, it is crucial to master the correct selection of the actuator, taking into account the prevention of overload (working torque higher than control torque). The operating torque is the main parameter for selecting actuators. The output torque of electrical equipment should be 1.2~1.5 times the operating torque of Lianggong valve. There are two main structures for actuators: one is without a thrust plate, which directly outputs torque; Another option is to configure thrust plates. At this point, the output torque is converted into output thrust through the valve stem nut in the thrust plate.
执行器输出轴旋转圈数与良工阀门阀门的公称直径、阀杆螺距、螺纹头数有关，按M计算。=H/ZS计算(公式中：M为电动设备应满足的总旋转圈数；H为良工阀门阀门的开启高度，mm；S是阀杆传动螺
The number of rotations of the actuator output shaft is related to the nominal diameter, stem pitch, and number of thread heads of the Lianggong valve, and is calculated according to M= H/ZS calculation (in the formula: M is the total number of rotations that electric equipment should meet; H is the opening height of Lianggong valve, mm; S is the valve stem transmission screw)
纹的螺距，mm；Z为阀杆螺纹头数。)对于多旋转的明杆良工阀门阀门，如果执行器允许通过的大阀杆直径不能通过所配良工阀门阀门的阀杆，则不能组装成电动良工阀门阀门。因此，电气设备中空输出轴的内径必须大于明杆良工阀门阀门的阀杆外径。良工阀门阀门的启闭速度快，容易产生水击现象。所以，应根据使用条件的不同，选择合适的启闭速度。安装、连接方式：良工阀门阀门的安装方式包括垂直安装、水平安装、落地安装。
Thread pitch of the pattern, mm; Z is the number of valve stem threads For multi rotating rising stem valves, if the large stem diameter allowed by the actuator cannot pass through the valve stem of the equipped valve, it cannot be assembled into an electric valve. Therefore, the inner diameter of the hollow output shaft of electrical equipment must be greater than the outer diameter of the stem of the rising stem valve. The opening and closing speed of Lianggong valve is fast, which is prone to water hammer phenomenon. Therefore, the appropriate opening and closing speed should be selected based on different usage conditions. Installation and connection methods: The installation methods of Lianggong valve include vertical installation, horizontal installation, and floor installation.
