進(jìn)口氣動(dòng)隔膜閥不需要單獨(dú)的閥桿填料密封結(jié)構(gòu)，隔膜在切斷介質(zhì)的同時(shí)起到了閥桿的密封作用，其二是柔韌性很強(qiáng)的隔膜關(guān)閉可靠，甚至對(duì)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(jìn)口氣動(dòng)隔膜閥產(chǎn)品詳情 Product details

氣動(dòng)隔膜閥由活塞式氣動(dòng)執(zhí)行機(jī)構(gòu)和隔膜閥組成,以壓縮空氣為動(dòng)力帶動(dòng)傳動(dòng)螺桿，使閥芯上下運(yùn)動(dòng)，同時(shí)拉動(dòng)膜片上進(jìn)口氣動(dòng)隔膜閥3.jpg下運(yùn)動(dòng)使其關(guān)閉和打開(kāi),并根據(jù)需要，可附裝反饋信號(hào)裝置或限位、定位裝置等，以適應(yīng)自控、程控、遙控或調(diào)節(jié)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(jìn)口氣動(dòng)隔膜閥 原理--

（單作用常開(kāi)式）當(dāng)氣源進(jìn)入氣缸控制腔，隔膜下壓，關(guān)閉閥門(mén)通道，當(dāng)氣缸控制腔無(wú)氣源壓力時(shí)，隔膜上升，閥門(mén)通道被打開(kāi) (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(dāng)氣源進(jìn)入氣缸控制腔，打開(kāi)閥門(mén)通道，當(dāng)氣缸控制腔無(wú)氣源壓力時(shí)，閥門(mén)通道被關(guān)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
