進(jìn)口防爆型電磁閥(德國(guó)OLES奧萊斯閥門)
【進(jìn)口防爆型電磁閥】工作原理:
防爆電磁閥是把設(shè)備可能點(diǎn)燃爆炸性氣體混合物的部件全部封閉在一個(gè)外殼內(nèi),其外殼能夠承受通過外殼任何接合面或結(jié)構(gòu)間隙,滲透到外殼內(nèi)部的可燃性混合物在內(nèi)部爆炸而不損壞,并且不會(huì)引起外部由一種、多種氣體或蒸氣形成的爆炸性環(huán)境的點(diǎn)燃,把可能產(chǎn)生火花、電弧和危險(xiǎn)溫度的零部件均放入隔爆外殼內(nèi),隔爆外殼使設(shè)備內(nèi)部空間與周圍的環(huán)境隔開。隔爆外殼存在間隙,因電氣設(shè)備呼吸作用和氣體滲透作用,使內(nèi)部可能存在爆炸性氣體混合物,當(dāng)其發(fā)生爆炸時(shí),外殼可以承受產(chǎn)生的爆炸壓力而不損壞,同時(shí)ZCSB防爆電磁閥外殼結(jié)構(gòu)間隙可冷卻火焰、降低火焰?zhèn)鞑ニ俣然蚪K止加速鏈,使火焰或危險(xiǎn)的火焰生成物不能穿越 隔爆間隙點(diǎn)燃外部爆炸性環(huán)境,從而達(dá)到隔爆目的。
The explosion-proof solenoid valve is to enclose all parts of the equipment that may ignite explosive gas mixture in a shell. The shell can withstand the explosion of the combustible mixture penetrating into the inner part of the shell through any joint surface or structural clearance of the shell without damage, and will not cause external explosion by one or more gases or steaming. The ignition of explosive environment formed by gas puts the parts that may produce sparks, arcs and dangerous temperatures into the flameproof housing, which separates the internal space of the equipment from the surrounding environment. There is a gap in the flameproof shell. Because of the breathing and gas permeation of electrical equipment, there may be explosive gas mixture inside. When explosion occurs, the shell can withstand the explosion pressure without damage. At the same time, the gap in the shell structure of ZCSB explosion-proof solenoid valve can cool the flame, reduce the flame propagation speed or terminate. Acceleration chain, so that flame or dangerous flame products can not cross the flameproof gap to ignite the external explosive environment, so as to achieve the purpose of flameproof.
【進(jìn)口防爆型電磁閥】應(yīng)用:
不銹鋼防爆電磁閥是不銹鋼電磁閥與防爆線圈組成,應(yīng)用于易燃易爆等危險(xiǎn)工作場(chǎng)合,防爆電磁閥可廣泛地應(yīng)用與紡織、印刷、化工、塑料、橡膠、制藥、食品、建材、機(jī)械、電器、表面處理等生產(chǎn)和科研部門以及科研、干燥設(shè)備、清洗設(shè)備、真空設(shè)備、電鍍涂裝、蒸餾機(jī)、濾油機(jī)、加濕器、食品機(jī)械、石油化工設(shè)施中。
【進(jìn)口防爆型電磁閥】維護(hù)說明:
1、不銹鋼防爆電磁閥建議使用單位指派專人負(fù)責(zé)使用保養(yǎng)。
2、防爆電磁閥安裝后,須通入介質(zhì)試動(dòng)作數(shù)次,確認(rèn)正常后方可投入正式使用。
3、應(yīng)定期清洗大閥內(nèi)外及銜鐵吸合面的污物。注意不要損壞密封面。
4、防爆電磁閥較長(zhǎng)時(shí)間不用時(shí),應(yīng)關(guān)閉閥前手動(dòng)閥,重新啟用時(shí),蒸汽電磁閥應(yīng)將冷凝水排除干凈,并作試動(dòng)作數(shù)次,待開關(guān)正常后方可投入使用。
5、防爆電磁閥從管路上卸下不用時(shí),應(yīng)將內(nèi)部零件試凈并用壓縮空氣吹凈儲(chǔ)存。
6、使用時(shí)間較長(zhǎng)時(shí),如活塞與閥座間密封不好,可將活塞密封面重新磨平,再和閥座研磨。
7、電磁閥工作時(shí),要注意閥門前后壓力表,要求工作壓力不得超過額定壓力,工作壓差必須在額定壓差范圍內(nèi)。當(dāng)工作壓力超過額定壓力或工作壓差超過額定壓差時(shí),電磁閥要停止使用,關(guān)閉前后手動(dòng)閥,以防止電磁閥爆炸和泄漏
