進口電動閘閥
電動閘閥概述:
電動閘閥閥簡單地說就是用電動執行器控制閘閥,從而實現閥門的開和關。其可分為上下兩部分,上半部分為電動執行器,下半部分為閥門動作力距比電動閥門大,電動閥門開關動作速度可以調整,結構簡單,易維護,動作過程中因氣體本身的緩沖特性,不易因卡住而損壞,但必須有氣源,且其控制系統也比電動閥門復雜。 電動閘閥響應靈敏,安全可靠,很多對控制要求高的廠專為氣動儀表控制元件設置壓縮空氣站。電動的就是要電。并能控制其流量的裝置。進口電動閘閥動作力距比電動閥門大,電動閥門開關動作速度可以調整,結構簡單,易維護,動作過程中因氣體本身的緩沖特性,不易因卡住而損壞,但必須有氣源,且其控制系統也比電動閥門復雜。 電動閘閥響應靈敏,安全可靠,很多對控制要求高的廠專為氣動儀表控制元件設置壓縮空氣站。進口電動閘閥并能控制其流量的裝置。其操作原理 電動閥通常由電動執行機構和閥門連接起來,經過安裝調試后成為電動閥。電動閥使用電能作為動力來接通電動執行機構驅動閥門,實現閥門的開關、調節動作。從而達到對管道介質的開關或是調節目的。

Electric gate valve is simply the electric actuator control valve, in order to achieve the valve on and off. It can be divided into two parts, the upper part of electric actuators, valve actuation torque than the lower half into a large electric valve, electric valve switching speed can be adjusted, simple structure, easy maintenance, the course of action because of the gas itself cushioning properties, not easy to get stuck due to damage, but there must be gas source, and its control system is also more complex than an electric valve. Electric valve response sensitive, safe and reliable, many of the requirements for the control of plant height pneumatic control components designed for setting air station. Electric power is to. And control means which can flow. Imported electric valve operation torque than the electric valve large, electric valve switching speed can be adjusted, simple structure, easy maintenance, the course of action due to buffering characteristics of the gas itself is not easy to get stuck due to damage, but there must be gas source, and its control system is also more complex than an electric valve. Electric valve response sensitive, safe and reliable, many of the requirements for the control of plant height pneumatic control components designed for setting air station. Imported electric valve and control device of its traffic. Its principle of operation is usually connected by electric valve actuators and valves up, after becoming the electric valve installation. Electric valve using electricity as the power to turn electric actuator valve drive, to achieve the valve switch, adjust the action. Switch the pipeline so as to achieve the purpose of the media or adjust.
Imported electric valve principle characteristics: it can be divided into two parts, the upper part of the electric actuator, the valve into the lower half.
進口電動執行器可分為三類,分別用于不同的閥門類別:
1、角行程:0~90°角行程,用于控制球閥、旋塞閥、蝶閥和百葉閥之類的角行程閥門;
2、多回轉式:需要運行超過360°才能實現閥門的啟閉,主要用于截止閥、管夾閥和隔膜閥;
3、直行程:輸出的是力,產生的是位移,主要用于閘閥和滑板閥。
進口電動閘閥安裝使用注意事項:
1、電動閘閥可安裝在水平管路或垂直管路上,單雙閘板閘閥應安裝在水平管路上,且手輪應位于閥門上方,不允許朝下安裝。
2、電動閘閥通常采用法蘭連接,特殊場合也有用焊接連接、螺紋連接。
3、對于大口徑及高壓的閘閥,啟閉力矩較大。為了減小啟閉力矩,可采用安裝旁通閥的辦法。旁通閥安裝在主閘閥外部,它的進出口與主閘閥的兩側練練連接,并聯聯通。主閘閥開啟前應先開通旁通閥,進入閥后,使主閘閥閘板前后的壓力差減小,從而減小主閘閥的開啟力矩。旁通閥口徑的選用應根據主閥口徑和使用要求考慮。
4、電動閘閥的介質溫度、壓力,對使用的可靠性應引起注意。在高溫、高壓時,由于溫度的變化可能使閘板鍥死,同時因各處介質溫度不均勻,易產生不密封現象。鍥式但閘板閥尤為明顯。
