一、快卸法兰进口气动真空(压力)球阀概述

V-GUQ型系列气动真空(压力)球阀是适用于真空系统中接通或切断管路中的介质流。该阀以压缩空气为动力，通过控制气动元件来改变气路方向，推动活塞齿条、齿轮的机械传动，以角行程输出扭矩来驱动球阀作启闭运动。阀门为直通式，靠球面密封，因而既能用在真空状态下，也能在低压状态下使用，并可任意位置安装。气缸分为双作用和单作用(弹簧复位)，可选配反馈信号装置及电气阀门定位器。

适用的工作介质为带酸、碱性的气体或液体。

The V-GUQ series pneumatic vacuum (pressure) ball valve is suitable for connecting or cutting off the medium flow in pipelines in vacuum systems. This valve is powered by compressed air and changes the direction of the pneumatic circuit by controlling the pneumatic components, driving the mechanical transmission of the piston rack and gear, and driving the ball valve to open and close with angular stroke output torque. The valve is a straight through type with a spherical seal, which can be used in both vacuum and low-pressure conditions, and can be installed in any position. The cylinder is divided into double acting and single acting (spring return), and can be optionally equipped with feedback signal device and electrical valve locator.

The suitable working medium is gas or liquid with acidic or alkaline properties.
