style="text-indent:25px">燃?xì)饩o急切斷閥的電磁線圈是用來產(chǎn)生驅(qū)動(dòng)閥門關(guān)閉所需的原動(dòng)力的部件。早先的傳統(tǒng)電磁線圈*由漆包線繞制而成，存在功耗大，長(zhǎng)時(shí)間通電容易燒毀線圈、不利于維修維護(hù)等問題，且*為通電工作型，即所謂的常開型。之后，有些廠家在線圈內(nèi)加入熱敏電阻或溫度開關(guān)，對(duì)長(zhǎng)時(shí)間通電的線圈起到限流作用，一定程度上減小線圈功耗，但通電時(shí)間仍然較長(zhǎng)，沒有很好解決功耗和溫升問題。近些年，隨著電子技術(shù)的普及，一些燃?xì)饩o急切斷閥生產(chǎn)廠已推出帶有內(nèi)部控制電路的新型低功耗電磁線圈。此類線圈一經(jīng)推出便受到許多用戶的歡迎，因?yàn)檫@類線圈不但可將功耗降至傳統(tǒng)線圈的1/20以下，還可制成斷電工作型，即所謂常閉型電磁線圈，使用于某些停電時(shí)需要切斷氣路的場(chǎng)合，如無(wú)人值守、地下管廊、自然災(zāi)害頻發(fā)地區(qū)等。使用單片機(jī)控制的低功耗線圈：其內(nèi)部使用控制芯片，可根據(jù)用戶的不同需求，通過事先寫入不同的程序，控制線圈通、斷電的時(shí)間和次數(shù)，從而對(duì)動(dòng)鐵心的吸合效果進(jìn)行控制。這種線圈的應(yīng)用面十分普遍。但對(duì)于電磁式燃?xì)饩o急切斷閥來說，很多功能是無(wú)用的，并且存在線圈內(nèi)部電路比較復(fù)雜、體積較大、成本較高等不利因素。</p><p style="text-indent:25px">燃?xì)饩o急切斷閥人為操作不當(dāng)故障，超壓操作。手搖油泵的設(shè)計(jì)壓力為4.0MPa，開閥所需的壓力為3.5～4.0MPa，而打壓高達(dá)7.0～8.0MPa的情況很多。每年大約有30臺(tái)車的油泵因超壓損壞要送修，其中有兩成無(wú)法修復(fù)應(yīng)更換。開閥程序錯(cuò)誤。違背打開緊急切斷閥務(wù)必在球閥關(guān)閉狀態(tài)下進(jìn)行的原則。經(jīng)常出現(xiàn)先打開球閥再打開緊急切斷閥的錯(cuò)誤，這就無(wú)法讓過流閥上下壓力平衡，由于存在壓差，小彈簧不能推開閥門。拼命加大油泵壓力不*打不開閥門，反而弄壞油泵。這是人員素質(zhì)低，不懂其工作原理造成的。燃?xì)饩o急切斷閥是安裝在燃?xì)鈨?chǔ)罐、管道出口處緊急時(shí)能夠快速切斷的閥門。</p><div

style="text-indent:25px">在選用切斷閥時(shí)，需要注意以下幾個(gè)關(guān)鍵參數(shù)：觸發(fā)機(jī)構(gòu)是決定閥門工作穩(wěn)定性的主要因素，氣密性是決定閥門關(guān)閉后截流能力的大小，合格的切斷閥應(yīng)能夠確保閥門關(guān)閉后無(wú)泄漏；流通量是指閥門全開時(shí)的流通能力，應(yīng)盡量選用閥口的流通面積大于或等于公稱通徑的產(chǎn)品。切斷時(shí)間是指從閥門關(guān)閉信號(hào)發(fā)出到閥門關(guān)閉的時(shí)間，應(yīng)盡量選用切斷時(shí)間小于或等于1s的產(chǎn)品。密封材料和殼體材料：閥門可使用的密封材料和殼體材料多種多樣，使用者可根據(jù)氣質(zhì)種類和使用壓力進(jìn)行選擇。燃?xì)饩o急切斷閥分為常開型、常閉型緊急切斷閥。蕪湖防爆緊急切斷閥公司</p><p
