進口氣動隔膜閥不需要單獨的閥桿填料密封結構，隔膜在切斷介質的同時起到了閥桿的密封作用，其二是柔韌性很強的隔膜關閉可靠，甚至對污液都能做到良好的切斷 The RETZ pneumatic diaphragm valve does not require a separate valve stem packing sealing structure. The diaphragm acts as a seal for the valve stem while cutting off the medium. Secondly, the highly flexible diaphragm provides reliable closure, and can even effectively cut off dirty liquids
進口氣動隔膜閥產品詳情 Product details
氣動隔膜閥由活塞式氣動執行機構和隔膜閥組成,以壓縮空氣為動力帶動傳動螺桿，使閥芯上下運動，同時拉動膜片上進口氣動隔膜閥3.jpg下運動使其關閉和打開,并根據需要，可附裝反饋信號裝置或限位、定位裝置等，以適應自控、程控、遙控或調節流量之用 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
進口氣動隔膜閥 原理--
（單作用常開式）當氣源進入氣缸控制腔，隔膜下壓，關閉閥門通道，當氣缸控制腔無氣源壓力時，隔膜上升，閥門通道被打開 (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
（單作用常閉式）當氣源進入氣缸控制腔，打開閥門通道，當氣缸控制腔無氣源壓力時，閥門通道被關閉 (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
