進口氣動高真空蝶閥以壓縮空氣為動力，帶動碟板旋轉來作啟閉運動，從而達到對管路氣流的接通或切斷。真空蝶閥是指工作壓力低于標準大氣壓，形成一定真空的閥門，是真空系統(tǒng)中用來調節(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。氣動真空蝶閥的閥板采用夾緊結構，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.
進口氣動高真空蝶閥結構特點
Structural characteristics
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。
該閥能對介質雙向截止，實現(xiàn)可靠的密封，雙向零泄漏。
軸封采用具有自動補償?shù)奶厥饨Y構，隔斷外界大氣與管道的連通，從而保證管道的真空度。
