產品概述
精小型閥門電動執行器用于控制0°~270°旋轉的閥門及其他同類產品,如蝶閥、球閥、風門、擋板閥、旋塞閥百葉閥等。可以廣泛應用于石油、化工、水處理、船舶、造紙、電站、供熱、輕工等各行業中。它以380V/220V/110V交流電源為驅動電源，以4-20mA電流信號或0-10VDC電壓信號為控制信號，可使閥門運動到所需位置，實現共其自動化控制，最大輸出扭距達4000N·m.
Electric actuator is used for control 0° ~ 270" rotation of the valves and other similar productsSuch as butterfly valve, ball valve,damper, flapper valves,cock etc.lt"'s widely used in petroleum ,chemicalwater treatment, shipping, paper, making ,power paints ,heating,light industry and other industries,ltdrives by 380V1220V/110VAC power,Control signal is 4-20mA current signal or0-10vDC voltage signalenables move the valve to the desired position ,achieving its automation,maximum output,torque is upto 4000N.m..
精小型閥門電動執行器性能特點Perrormance Features
1 、殼體Shell
殼體為硬質鋁合金,經陽極氧化處理和聚酯粉未涂層,耐腐蝕性強,防護等級為IP67.NEMA4和6,并有IP68型供選擇.
The Shell is made ofhorniness aluminum alloy, pass through anodic oxidation treatment andpolyester powder coating ,so it has strong corrosion resistance.Protection grade is IP67, NEMA4 and6.and optionallP68 type.
2 、電機Electric Machinery
全封閉式鼠籠式電機，體積小，扭距大，慣性力小，絕緣等級為F級，內置熱保護開關，可防止損壞電機.
Fully enclosed squirrel-cage electric Machinery, small volume,large torque,and small inertiaforce, F-class,insulation rating ,inside hot protection switch,avoid damaging the electric machinery.
3、手動結構ManualStructure
手柄的設計保證安全可靠、省力、體積小，不通電時，扳動手柄可進行手動操作，不用手動時，將扳手置于扳手夾內，方便使用。
The design of handle ensure safe, reliable, labor-saving, small volume,Whenit don't have electricityit can be manually, operated by handle When you don't operate by manus,you can put the wrench in thewrench folder.then you can easy to use it.
4、指示器Indicator指示器安裝在中心軸上,可以觀察閥門位置,透鏡采用凸出鏡設計，不積水，觀察更方便。Indicator installs in the center axis, so it can observes the valve position, it adopts convex mirrordesign.nocumulate water, more convenient to observe.
5 、干燥器Space Heater
用來控制溫度,防止由于溫度和天氣變化導致執行器內部水分凝結,保持內部電氣元件的干燥It is Used for control temperature, avoiding internal moistuer of electric actuator condensedbecause of the changing changing oftemperature and weather,keep inner electricdevice dry,
6 、密封Sealing
密封性好,標準產品防護等級是IP67.并可選IP68防護等級.
Good sealing, performance,and the protection class ofstandard product is IP67, and optional lp68protection grade.
