莱克电动蝶阀的工作原理及结构与适用环境分析：

进口电动蝶阀的蝶板安装于管道的直径方向。在电动蝶阀阀体圆柱形通道内，圆盘形蝶板绕着轴线旋转，旋转角度为0°~90°之间，旋转到90°时，阀门则牌全开状态。 
电动蝶阀结构简单、体积小、重量轻，只由少数几个零件组成。而且只需旋转90°即可快速启闭，操作简单，同时该阀门具有良好的流体控制特性。电动蝶阀处于完全开启位置时，蝶板厚度是介质流经阀体时的阻力，因此通过该阀门所产生的压力降很小，故具有较好的流量控制特性。电动蝶阀有弹密封和金属的密封两种密封型式。弹性密封阀门，密封圈可以镶嵌在阀体上或附在蝶板周边。 
采用金属密封的阀门一般比弹性密封的阀门寿命长，但很难做到完全密封。金属密封能适应较高的工作温度，弹性密封则具有受温度限制的缺点。 
如果要求电动蝶阀作为流量控制使用，主要的是正确选择阀门的尺寸和类型。电动蝶阀的结构原理尤其适合制作大口径阀门。电动蝶阀不仅在石油、煤气、化工、水处理等一般工业上得到广泛应用，而且还应用于热电站的冷却水系统。 
常用的电动蝶阀有对夹式电动蝶阀和法兰式电动蝶阀两种。对夹式电动蝶阀是用双头螺栓将阀门连接在两管道法兰之间，法兰式电动蝶阀是阀门上带有法兰，用螺栓将阀门上两端法兰连接在管道法兰上。

Electric butterfly valve working principle and structure and applicable environmental analysis: 
Electric butterfly valve plate mounted on the pipe diameter direction. Electric butterfly valve in the cylindrical channel, disc-shaped disc around the axis of rotation, rotation angle of between 0 ° ~ 90 °, rotation to 90 °, the valve is fully open state licensing. 
Electric butterfly valve simple structure, small size, light weight, only by a few parts. And just rotate 90 ° to quickly open and close, easy to operate, while the fluid control valve has a good feature. Electric butterfly valve in the fully open position, the disc thickness is only when the medium flows through the body resistance, produced by the valve pressure drop is small, it has a better flow control characteristics. Electric Butterfly shells sealed and two metal seal type. Resilient seal valves, seals can be mounted on the body or attached to the disc periphery. 
Using a long metal seal valve life in general than the elastic sealing valve, but it is difficult to completely seal. Metal seals can adapt to higher operating temperature, flexible seal is affected by temperature limit of the defect. 
If you require the use of electric flow control valve as the main choice is the right size and type of valve. Electric Butterfly structural principle is particularly suitable for production of large diameter valves. Electric Butterfly has not only been widely used in the oil, gas, chemical, water treatment and other general industrial, but also used in thermal power plant cooling water system. 
Commonly used electric butterfly valve has two wafer type butterfly valve and flanged electric motor. Wafer electric butterfly valve with stud connection between two pipe flanges, flanged electric butterfly valve is a valve with a flange with bolt flanged ends of the valve on the pipe flange.

执行器的工作原理

原文：
执行器的工作原理：
在齿轮级，发动机的转速可通过两套齿轮传送到输出杆上。主减速器由行星齿轮完成，副减速器由蜗轮实现，它被一套绷紧的弹簧固定在中心位置。在发生过载的情况下，也就是输出杆超过了弹簧的设定转矩时，中点蜗轮会发生轴向位移，对开关及信号装置进行微调，为系统提供保护。 气动执行器受由外部变化控制杆操纵的耦合的作用，输出杆在发动机工作时与蜗轮耦合，在手动操作时与手轮耦合。当发动机不工作时，可以很容易地断掉电机驱动，并且只需压一下控制杆即可连上手轮。由于电机驱动优先于手动操作，因此当发动机再次启动时，会自动发生反向动作。这样就可以避免当发动机运转时还开启手轮，有利于保护系统。由于手轮直接与输出杆耦合，因此可以保证在内部齿轮失灵或损坏时阀门的正常手动操作。
安装在齿轮上的开关与信号装置是一个密封外壳，保护其内部的元件实现以下功能：
(1)本地或远程显示阀门位置
(2)执行器/阀门的过载保护
(3)限定阀门行程范围

 (4)电气接口

气动执行器在不同型号阀门上的安装是通过输出杆来完成的，它可适用于现有的多种阀杆组态。

The working principle of actuators:
In the gear level, the engine speed by two sets of gear transmission to the output shaft. Lord done by planetary gear speed reducer, deputy implemented by worm gear speed reducer, it is a tension spring is fixed in a central location. In the event of overload of cases, that is, the output than the spring setting torque, the worm gear axial displacement happens, fine-tuning, switch and signal device for for the system to provide protection. Pneumatic actuators to control lever manipulation by external change coupling effect, the output shaft with worm gear coupling, when engine working in manual operation with handwheel coupling. When the engine does not work, can be easily broken motor drive, and only need to press the control rod is connected the handwheel. Because motor driven in preference to manual operation, when the engine starts, again will happen automatically reverse action. So you can avoid also open the handwheel when when the engine is running, is advantageous to the protection system. 
Due to the handwheel directly with the output shaft coupling, thus can guarantee the internal gear failure or damage to the normal manual operation of the valve. 
Installed on the gear switch and signal device is a sealed enclosure, to protect the internal components to achieve the following functions: 
(1) local or remote display position of the valve 
(2) actuators/valves of overload protection 
(3) limit range of the valve 
(4) electrical interface 
Pneumatic actuators on the different type valve installation is done through the output shaft, it can be applied to existing stem configuration.
