进口气动高真空蝶阀以压缩空气为动力,带动碟板旋转来作启闭运动,从而达到对管路气流的接通或切断。真空蝶阀是指工作压力低于标准大气压,形成一定真空的阀门,是真空系统中用来调节气流量、切断和接通管路的元件,一般用于控制空气和非腐蚀性气体。气动真空蝶阀的阀板采用夹紧结构,把阀板的密封圈夹紧,泄露量为零,除了能用在真空状态下,也能在低压状态下使用。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.

进口气动高真空蝶阀结构特点 Structural characteristics

轴承采用自润滑轴承,摩擦阻力小。

不必从管路上拆卸阀门即可更换蝶板密封圈。

该阀能对介质双向截止,实现可靠的密封,双向零泄漏。

轴封采用具有自动补偿的特殊结构,隔断外界大气与管道的连通,从而保证管道的真空度。
