萊克電動蝶閥的工作原理及結(jié)構(gòu)與適用環(huán)境分析：

進(jìn)口電動蝶閥的蝶板安裝于管道的直徑方向。在電動蝶閥閥體圓柱形通道內(nèi)，圓盤形蝶板繞著軸線旋轉(zhuǎn)，旋轉(zhuǎn)角度為0°~90°之間，旋轉(zhuǎn)到90°時，閥門則牌全開狀態(tài)。 
電動蝶閥結(jié)構(gòu)簡單、體積小、重量輕，只由少數(shù)幾個零件組成。而且只需旋轉(zhuǎn)90°即可快速啟閉，操作簡單，同時該閥門具有良好的流體控制特性。電動蝶閥處于完全開啟位置時，蝶板厚度是介質(zhì)流經(jīng)閥體時的阻力，因此通過該閥門所產(chǎn)生的壓力降很小，故具有較好的流量控制特性。電動蝶閥有彈密封和金屬的密封兩種密封型式。彈性密封閥門，密封圈可以鑲嵌在閥體上或附在蝶板周邊。 
采用金屬密封的閥門一般比彈性密封的閥門壽命長，但很難做到完全密封。金屬密封能適應(yīng)較高的工作溫度，彈性密封則具有受溫度限制的缺陷。 
如果要求電動蝶閥作為流量控制使用，主要的是正確選擇閥門的尺寸和類型。電動蝶閥的結(jié)構(gòu)原理尤其適合制作大口徑閥門。電動蝶閥不僅在石油、煤氣、化工、水處理等一般工業(yè)上得到廣泛應(yīng)用，而且還應(yīng)用于熱電站的冷卻水系統(tǒng)。 
常用的電動蝶閥有對夾式電動蝶閥和法蘭式電動蝶閥兩種。對夾式電動蝶閥是用雙頭螺栓將閥門連接在兩管道法蘭之間，法蘭式電動蝶閥是閥門上帶有法蘭，用螺栓將閥門上兩端法蘭連接在管道法蘭上。

Electric butterfly valve wong 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 cool 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 cool 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 cool 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.

 

 

執(zhí)行器的工作原理

原文：
執(zhí)行器的工作原理：
在齒輪級，發(fā)動機(jī)的轉(zhuǎn)速可通過兩套齒輪傳送到輸出桿上。主減速器由行星齒輪完成，副減速器由蝸輪實現(xiàn)，它被一套繃緊的彈簧固定在中心位置。在發(fā)生過載的情況下，也就是輸出桿超過了彈簧的設(shè)定轉(zhuǎn)矩時，中央蝸輪會發(fā)生軸向位移，對開關(guān)及信號裝置進(jìn)行微調(diào)，為系統(tǒng)提供保護(hù)。 氣動執(zhí)行器受由外部變化控制桿操縱的耦合的作用，輸出桿在發(fā)動機(jī)工作時與蝸輪耦合，在手動操作時與手輪耦合。當(dāng)發(fā)動機(jī)不工作時，可以很容易地斷掉電機(jī)驅(qū)動，并且只需壓一下控制桿即可連上手輪。由于電機(jī)驅(qū)動優(yōu)先于手動操作，因此當(dāng)發(fā)動機(jī)再次啟動時，會自動發(fā)生反向動作。這樣就可以避免當(dāng)發(fā)動機(jī)運轉(zhuǎn)時還開啟手輪，有利于保護(hù)系統(tǒng)。由于手輪直接與輸出桿耦合，因此可以保證在內(nèi)部齒輪失靈或損壞時閥門的正常手動操作。
安裝在齒輪上的開關(guān)與信號裝置是一個密封外殼，保護(hù)其內(nèi)部的元件實現(xiàn)以下功能：
(1)本地或遠(yuǎn)程顯示閥門位置
(2)執(zhí)行器/閥門的過載保護(hù)
(3)限定閥門行程范圍

 (4)電氣接口

氣動執(zhí)行器在不同型號閥門上的安裝是通過輸出桿來完成的，它可適用于現(xiàn)有的多種閥桿組態(tài)。

The wong 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 ceal 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 cool lever manipulation by external change coupling effect, the output shaft with worm gear coupling, when engine wong in manual operation with handwheel coupling. When the engine does not work, can be easily broken motor drive, and only need to press the cool 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.
