評(píng)論: 更新日期:2016年07月09日

    本人是寶清縣鍋爐壓力容器檢驗(yàn)所一名特種設(shè)備檢驗(yàn)                                                               
    員,于2010年開始從事安全閥校驗(yàn)工作,工作3年中共校驗(yàn)安全閥300余只。下面我談?wù)勅绾巫龊冒踩y的維護(hù)和檢查工作。                                                               
    要使安全閥動(dòng)作靈敏、可靠和密封性能良好,必須在鍋                                                               
    爐、壓力容器、壓力管道的運(yùn)行過(guò)程中加強(qiáng)維護(hù)和檢查。                                                               
    (一)要經(jīng)常保持安全閥的清潔,防止閥體彈簧等被油                                                               
    垢臟物填滿或被腐蝕,防止安全閥排放管被油污或其他異物堵塞。經(jīng)常檢查鉛封是否完好,防止杠桿式安全閥的重錘松動(dòng)或被移動(dòng),防止隨意擰動(dòng)。                                                               
    (二)發(fā)現(xiàn)安全閥有泄漏跡象時(shí),應(yīng)時(shí)及更換或檢修。                                                               
    禁止用加大載荷(如過(guò)分?jǐn)Q緊彈簧式安全閥的調(diào)節(jié)螺絲或在杠桿式安全閥的杠桿上加掛重物等)的方法來(lái)消除泄漏。為防止閥瓣和閥座被氣體中的油垢等臟物粘住,致使安全潤(rùn)不能正常開啟,對(duì)用于空氣、蒸汽或帶有粘滯性臟物但排放不                                                               
    會(huì)造成危害的其他氣體的安全閥,應(yīng)定期做手提排放試驗(yàn)。                                                               
    (三)為保持安全閥靈敏可靠,每年至少做一次定期校                                                               
    驗(yàn)。定期校驗(yàn)的內(nèi)容一般包括動(dòng)態(tài)檢查和解體檢查。動(dòng)態(tài)檢查的主要內(nèi)容是檢查安全閥的開啟壓力、回座壓力、密封程度以及在額定排放壓力下的開啟高度等,其要求與安全閥調(diào)試時(shí)相同。若動(dòng)態(tài)檢查不合格,或在運(yùn)行中發(fā)現(xiàn)有泄漏等異                                                                                                                                   
    常情況時(shí),則應(yīng)作解體檢查。解體后仔細(xì)檢查安全閥的所有零部件有無(wú)裂紋、傷痕、磨損、腐蝕、變形等情況,并根據(jù)缺陷的大小和損壞程度予以修復(fù)或更換,最后組裝,進(jìn)行動(dòng)態(tài)檢查。                                                               
    特種設(shè)備使用單位要高度重視安全閥的故障消除、維修和檢查(維護(hù))工作以及相關(guān)事故的教訓(xùn)警示和安全閥在承壓類特種設(shè)備上的重要性。                                                               
    特種設(shè)備使用單位應(yīng)貫徹執(zhí)行《特種設(shè)備安全監(jiān)察條例》,嚴(yán)格遵守安全操作規(guī)程和規(guī)章制度,除對(duì)在用的承壓類特種設(shè)備本體進(jìn)行經(jīng)常性的日常維護(hù)保養(yǎng)和檢查外,也要對(duì)其安全附件按規(guī)定進(jìn)行定期校驗(yàn)和維護(hù),并納入特種設(shè)備安全管理工作,對(duì)發(fā)現(xiàn)的隱患,及時(shí)整改,消除隱患,并真正落實(shí)企業(yè)主體責(zé)任,確保特種設(shè)備的安全運(yùn)行。

    安全閥校驗(yàn)工作總結(jié)                                                                                                                               
    本人是漯河市特種設(shè)備安全檢測(cè)中心一名特種設(shè)備檢驗(yàn)人員。于2010年開始從事安全閥校驗(yàn)工作,工作3年中共校驗(yàn)安全閥500余只。下面我談?wù)勅绾巫龊冒踩y的維護(hù)和檢查工作。  要使安全閥動(dòng)作靈敏、                                                                                                                                                                                               
    可靠和密封性能良好                                                               
    器、壓力管道的運(yùn)行過(guò)程中加強(qiáng)維護(hù)和檢查。                                                                                                                                                                                                                                                               
    一、                                                               
    滿或被腐蝕,防止安全閥排放管被油污或其他異物堵塞。經(jīng)常檢查鉛                                                                                                                                                                                               
    封是否完好,                                                               
    動(dòng)。                                                                                                                                                                                                                                                               
    二、發(fā)現(xiàn)安全閥有泄漏跡象時(shí),應(yīng)時(shí)及更換或檢修。禁止用加大載荷(如過(guò)分?jǐn)Q緊彈簧式安全閥的調(diào)節(jié)螺絲或在杠桿式安全閥的杠桿上加掛重物等)的方法來(lái)消除泄漏。為防止閥瓣和閥座被氣體中的油垢等臟物粘住,致使安全潤(rùn)不能正常開啟,對(duì)用于空氣、蒸汽或帶有粘滯性臟物但排放不會(huì)造成危害的其他氣體的安全閥,應(yīng)定期做手提排放試驗(yàn)。                                                                                                                                                                                               
    三、為保持安全閥靈敏可靠,每年至少做一次定期校驗(yàn)。定期校驗(yàn)的內(nèi)容一般包括動(dòng)態(tài)檢查和解體檢查。動(dòng)態(tài)檢查的主要內(nèi)容是檢查安全閥的開啟壓力、回座壓力、                                                                                                                                                                                               
    密封程度以及在額定排放壓力下的運(yùn)行中發(fā)現(xiàn)有泄漏等異常情況時(shí)則應(yīng)作解體檢查。解體后仔細(xì)檢查安                                                                                                                                                                                                                                                                   
    據(jù)缺陷的大小和損壞程度予以修復(fù)或更換,最后組裝,進(jìn)行動(dòng)態(tài)檢查。                                                               
    特種設(shè)備使用單位要高度重視安全閥的故障消除、維修和檢查維護(hù),工作以及相關(guān)事故的教訓(xùn)警示和安全閥在承壓類特種設(shè)備上的重要性。

    安全閥的種類很多,但通常按以下方法進(jìn)行分類。                                                               
    按結(jié)構(gòu)形式分類 根據(jù)結(jié)構(gòu)特點(diǎn)或閥瓣最大開啟高度與閥座直徑之比(h/d),安全閥一般可以分為以下幾種:                                                               
    1) 杠桿重錘式安全閥。重錘的作用力通過(guò)杠桿放大后加載于閥瓣。在閥門開啟和關(guān)閉過(guò)程                                                               
    中載荷的大小不變,因此由閥桿傳來(lái)的力基本上是不變的。其缺點(diǎn)是對(duì)振動(dòng)較敏感,且回座性能較差。這種結(jié)構(gòu)的安全閥只能用在固定設(shè)備上,重錘的重量一般不應(yīng)超過(guò)60kg,以免操作困難。                                                               
    2) 彈簧式安全閥。 利用壓縮彈簧的力來(lái)平衡閥瓣的壓力,并使其密封的安全閥。 該類安                                                               
    全閥的優(yōu)點(diǎn)在于比重錘式安全閥輕便,靈敏度高,安裝位置沒(méi)嚴(yán)格限制。缺點(diǎn)是作用在閥桿上的力隨彈簧的變形而產(chǎn)生變化;同時(shí),當(dāng)溫度較高時(shí),應(yīng)注意彈簧的隔熱和散熱。這類安全閥的彈簧作用力一般不應(yīng)超過(guò)20000n;過(guò)大、過(guò)硬的彈簧不適于精確的工作。                                                               
    3) 脈沖式安全閥,又稱先導(dǎo)式安全閥。 它把主閥和輔閥設(shè)計(jì)在一起,通過(guò)輔閥的脈沖作                                                               
    用帶動(dòng)主閥動(dòng)作。這種結(jié)構(gòu)通常用于大口徑、大排量及高壓系統(tǒng)。                                                               
    大直徑疏水管路上用的脈沖式安全閥,也是有主閥和輔閥組成。輔閥為口徑很小的直接載荷式安全閥,它與主閥相連。當(dāng)系統(tǒng)超壓時(shí),輔閥首先開啟,排放介質(zhì),從而驅(qū)動(dòng)或控制主閥閥瓣開啟,大量排放介質(zhì)。                                                               
    4) 微啟式安全閥。 閥瓣的開啟高度為閥座通徑的1/20~1/40,即安全閥的閥瓣開啟高度很                                                               
    小,適用于液體介質(zhì)和排量不大的場(chǎng)合。由于液體介質(zhì)是不可壓縮的。少量排除即可使壓力下降。                                                               
    5) 全啟式安全閥。閥瓣的開啟高度為閥座通徑的1/4~1/3。在安全閥的閥瓣處設(shè)有反沖盤,                                                               
    借助于氣體介質(zhì)的膨脹沖力,使閥瓣開啟到足夠的高度,從而達(dá)到排量要求。這種結(jié)構(gòu)的安全閥使用較多,靈敏度亦較高,但兩個(gè)調(diào)節(jié)環(huán)的位置很難調(diào)整,必須十分認(rèn)真調(diào)整才能達(dá)到要求,這對(duì)初次使用者帶來(lái)很多困難。因此,又開發(fā)了一種被簡(jiǎn)化了的結(jié)構(gòu)。這種結(jié)構(gòu)的調(diào)整較為方便,但靈敏度稍受影響。若用于一般蒸汽鍋爐和蒸汽管道上影響不大。                                                               
    6) 全封閉式安全閥。安全閥開排放時(shí),介質(zhì)不會(huì)向外界泄漏,而是通過(guò)排泄管排放掉。這                                                               
    種結(jié)構(gòu)適用于易燃、易爆,有毒有害介質(zhì)。                                                               
    7) 半封閉式安全閥。 安全閥開啟排放時(shí),介質(zhì)一部分通過(guò)排泄管排放,而另一部分從閥                                                               
    蓋與閥桿的配合處向外泄漏。這種結(jié)構(gòu)的安全閥適用于一般蒸汽和對(duì)環(huán)境無(wú)污染的介質(zhì)。                                                               
    8) 敞開式安全閥。安全閥開啟排放時(shí),介質(zhì)不引導(dǎo)管道或容器內(nèi),而直接由閥瓣上方排放                                                                                                                                   
    到大氣中。這種安全閥適用于對(duì)環(huán)境無(wú)污染的介質(zhì)。                                                               
    9) 先導(dǎo)式安全閥。先導(dǎo)式安全閥由一個(gè)主閥和一個(gè)先導(dǎo)閥組成。主閥是真正的安全閥,而                                                               
    先導(dǎo)閥的作用是感受壓力系統(tǒng)的壓力并使主閥開啟和關(guān)閉。主閥包括閥體和關(guān)閉件以及一個(gè)驅(qū)動(dòng)機(jī)構(gòu)。驅(qū)動(dòng)機(jī)構(gòu)可以和閥體做成一體,也可以置于閥體之外。主閥還可以由一個(gè)直接作用式安全閥附加一個(gè)驅(qū)動(dòng)機(jī)構(gòu)組成。先導(dǎo)式安全閥還可以設(shè)計(jì)成在正常運(yùn)行條件下作為控制閥,而在異常運(yùn)行條件下作為安全閥使用。                                                               
    此外,從安全閥的外部結(jié)構(gòu)上還可以分為有扳手和無(wú)扳手安全閥、有散熱片和無(wú)散熱片安全閥、有波紋管和無(wú)波紋管安全閥等幾類。有扳手的安全閥在緊急情況下,可以由人工泄壓;有散熱片的安全閥適用于介質(zhì)溫度在300℃以上的場(chǎng)合;有波紋管的安全閥適用于腐蝕性介質(zhì)或背壓波動(dòng)較大的場(chǎng)合。篇五:2013工作總結(jié)安監(jiān)部
