(衬胶，衬氟)进口气动隔膜阀由活塞式气动执行机构和隔膜阀组成,以压缩空气为动力带动传动螺杆，使阀芯上下运动，同时拉动膜片上下运动使其关闭和打开,并根据需要，可附装反馈信号装置或限位、定位装置等，以适应自控、程控、遥控或调节流量之用 RETZ (Rubber lined, fluorine lined) Pneumatic diaphragm valve is composed of piston type pneumatic actuator and diaphragm valve. The compressed air is used as the power to drive the transmission screw to move the valve core up and down, while pulling the diaphragm up and down to close and open. Feedback signal devices or limit and positioning devices can be attached as required to adapt to automatic control, program control, remote control or flow regulation

(衬胶，衬氟)进口气动隔膜阀 原理--

（单作用常开式）当气源进入气缸控制腔，隔膜下压，关闭阀门通道，当气缸控制腔无气源压力时，隔膜上升，阀门通道被打开 (Single acting normally open type) When the air source enters the cylinder control chamber, the diaphragm is pressed down and the valve passage is closed. When there is no air source pressure in the cylinder control chamber, the diaphragm rises and the valve passage is opened

（单作用常闭式）当气源进入气缸控制腔，打开阀门通道，当气缸控制腔无气源压力时，阀门通道被关闭 (Single acting normally closed type) When the air source enters the cylinder control chamber, open the valve channel. When there is no air source pressure in the cylinder control chamber, the valve channel is closed
