上海喜開(kāi)理切換閥 CKD切換閥的開(kāi)關(guān)是由通過(guò)電磁閥來(lái)的信號(hào)壓縮空氣控制的。根據(jù)在流程中起的作用不同，有空氣、污氮切換閥，純氮抑制閥、污氮三通閥等。從結(jié)構(gòu)型式分，有立式和臥式兩種。立式切換閥又可以分為氣開(kāi)式和氣閉式兩種。氣開(kāi)式是指信號(hào)壓縮空氣斷氣時(shí)，閥瓣依靠自重能自動(dòng)打開(kāi)；反之為氣閉式。氣開(kāi)、氣閉的選擇由裝置的安全性確定。氮?dú)馇袚Q閥用氣開(kāi)式，空氣切換閥用氣閉式。4GA110-M5-AC220V

喜開(kāi)理切換閥的動(dòng)作是由電磁閥來(lái)控制的，除了注意選擇氣開(kāi)、氣閉式，以防止氣源故障帶來(lái)危害之外，還應(yīng)注意電磁閥狀態(tài)與切換閥狀態(tài)的配合，以使電源發(fā)生故障時(shí)不致危及設(shè)備安全。現(xiàn)分別說(shuō)明如下：
1、污氮切換閥。當(dāng)四通電磁閥有電時(shí)，切換閥關(guān)閉。失電時(shí)，切換閥開(kāi)。而且當(dāng)電源失電時(shí)，氣源失壓時(shí)，也能借自重打開(kāi)。從而保證了出現(xiàn)故障時(shí)，上塔氣體能通過(guò)蓄冷器放空，不致造成超壓。
2、空氣切換閥。當(dāng)四通電磁閥有電時(shí)，切換閥打開(kāi)。失電時(shí)，切換閥關(guān)閉。當(dāng)控制電源故障失電時(shí)，切換閥關(guān)閉；當(dāng)控制氣源故障失壓時(shí)，切換閥借自重關(guān)閉，保證出現(xiàn)故障時(shí)原料空氣不進(jìn)入空分塔。
3、污氮（純氮）三通切換閥。四通電磁閥有電，三通切換閥處于排送位置；四通電磁閥失電，三通切換閥處于放空位置。當(dāng)電源故障失電時(shí)，三通切換閥處于放空位置；當(dāng)氣源故障失壓時(shí)，三通切換閥能借自重處于放空位置。
