進(jìn)口氣動(dòng)高真空蝶閥以壓縮空氣為動(dòng)力，帶動(dòng)碟板旋轉(zhuǎn)來作啟閉運(yùn)動(dòng)，從而達(dá)到對(duì)管路氣流的接通或切斷。真空蝶閥是指工作壓力低于標(biāo)準(zhǔn)大氣壓，形成一定真空的閥門，是真空系統(tǒng)中用來調(diào)節(jié)氣流量、切斷和接通管路的元件，一般用于控制空氣和非腐蝕性氣體。氣動(dòng)真空蝶閥的閥板采用夾緊結(jié)構(gòu)，把閥板的密封圈夾緊，泄露量為零，除了能用在真空狀態(tài)下,也能在低壓狀態(tài)下使用。The pneumatic high vacuum butterfly valve is powered by compressed air and drives the disc plate to rotate for opening and closing motion, thereby achieving the connection or disconnection of the pipeline airflow. Vacuum butterfly valve refers to a valve whose working pressure is lower than the standard atmospheric pressure, forming a certain vacuum. It is a component used in the vacuum system to regulate air flow, cut off and connect pipelines, and is generally used to control air and non corrosive gases. The valve plate of the pneumatic vacuum butterfly valve adopts a clamping structure to clamp the sealing ring of the valve plate, with zero leakage. It can be used not only in vacuum state but also in low pressure state.

軸承采用自潤滑軸承，摩擦阻力小。

不必從管路上拆卸閥門即可更換蝶板密封圈。

該閥能對(duì)介質(zhì)雙向截止，實(shí)現(xiàn)可靠的密封，雙向零泄漏。

軸封采用具有自動(dòng)補(bǔ)償?shù)奶厥饨Y(jié)構(gòu)，隔斷外界大氣與管道的連通，從而保證管道的真空度。
