開關型不銹鋼電動閘閥介紹

一,、開關型不銹鋼電動閘閥,，由不銹鋼閘閥與開關型多回轉閥門電動裝置組成，是一種做直線往復運動的閥門,控制方式有開關型,、智能開關型,、防爆型、調節(jié)型,，可根據(jù)需求選擇控制方式,。此閥門操作簡單是一種zui常見的啟閉閥,它利用閘板的上下工作來接通和關斷管道中的流體介質。適用于現(xiàn)控,、遠控,、易爆場合、不易手動場合等截斷或接通管路中的介質,。廣泛用于電力,、冶金、石油,、化工,、造紙、污水處理等部門,。

二,、具有以下優(yōu)點； 

1．流體阻力小,，密封面受介質的沖刷和侵蝕小。 

2．開閉較省力,。 

3．介質流向不受限制,，不擾流、不降低壓力,。 

4.閥門采用壓力自緊式密封或閥體,、閥蓋墊片密封結構，值得信賴,！使用安全可靠,。

5.電動裝置配有轉矩控制機構,、現(xiàn)場操作機構和手、電動切換機構,。除就地操作外,，還可以進行遠距離操作、PLC控制,、4~20mA電流輸入輸出智能控制等,。

6.手動閥門由手動機構或撞擊時手輪開啟。減小閥門操作力,。

7．形體簡單,，結構長度短，制造工藝性好,，適用范圍廣,。 

8.初次安裝和調試時，必須手動把閥門開到約一半的位置,，以免電機相序接反導致閥門或電裝損壞,。
