開關(guān)型不銹鋼電動閘閥介紹

一,、開關(guān)型不銹鋼電動閘閥,，由不銹鋼閘閥與開關(guān)型多回轉(zhuǎn)閥門電動裝置組成,，是一種做直線往復(fù)運動的閥門,控制方式有開關(guān)型,、智能開關(guān)型、防爆型,、調(diào)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(guān)斷管道中的流體介質(zhì),。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(zhì),。廣泛用于電力、冶金,、石油,、化工、造紙,、污水處理等部門,。

二、開關(guān)型不銹鋼電動閘閥具有以下優(yōu)點,； 

1．流體阻力小,，密封面受介質(zhì)的沖刷和侵蝕小。 

2．開閉較省力,。 

3．介質(zhì)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(jié)構(gòu)，值得信賴,！使用安全可靠,。

5.電動裝置配有轉(zhuǎn)矩控制機構(gòu)、現(xiàn)場操作機構(gòu)和手,、電動切換機構(gòu),。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(gòu)或撞擊時手輪開啟。減小閥門操作力,。

7．形體簡單,，結(jié)構(gòu)長度短，制造工藝性好,，適用范圍廣,。 

8.初次安裝和調(diào)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(dǎo)致閥門或電裝損壞,。
