ASCO電磁閥泄漏的措施(shi)及安裝尺寸

　　1.ASCO電磁閥設計單位(wei)應考慮周全

　　在(zai)ASCO電磁閥選型時，閥門設計單位(wei)應詳細了解各種類(lei)型閥門的內部(bu)結(jie)構(gou)(gou)和油氣管(guan)道輸送的介(jie)質(zhi)、溫(wen)度、流速、流量、站(zhan)場氣溫(wen)等情(qing)況，并結(jie)合(he)工藝、操(cao)作和等諸因素，選擇壓(ya)力(li)等級與(yu)結(jie)構(gou)(gou)形式合(he)理、口徑與(yu)材質(zhi)滿足使用(yong)要求、便(bian)于(yu)現(xian)場維護的閥門，具體包(bao)括以下4個方面。

　　1)油氣管道輸送介質的工(gong)作壓力、工(gong)作溫度、環境溫度、腐蝕性大小(xiao)，是(shi)否(fou)含有(you)固體顆粒，是(shi)否(fou)有(you)毒(du)，是(shi)否(fou)易(yi)燃(ran)或易(yi)爆等。

　　2)閥門對油氣管(guan)道輸送(song)介質特性(xing)的要(yao)求，如流阻、排放能力、流量特性(xing)、密(mi)封(feng)等(deng)級等(deng)。

　　3)油氣管道(dao)對閥(fa)門安(an)裝(zhuang)尺(chi)寸和外(wai)形尺(chi)寸要求(qiu)，如公稱(cheng)通徑、與管道(dao)的(de)連接方(fang)式(shi)、安(an)裝(zhuang)尺(chi)寸、外(wai)形尺(chi)寸或重量限(xian)制等。

　　4)油氣管道(dao)對閥門產品(pin)的性、使用壽(shou)命維護(hu)保養(yang)以及電動裝置的性能等附加要求。

　　2.ASCO電(dian)磁閥生產企業應實(shi)行

　　ASCO電磁閥泄(xie)漏的(de)源頭，因此，閥門生產企業除(chu)按(an)照有關規(gui)定取得《特種設備壓(ya)力管(guan)道制(zhi)造許可(ke)證》、《質(zhi)量(liang)管(guan)理體系認證證書》和采購閥門單位要求(qiu)的(de)資質(zhi)(如API相關證書)外(wai)，還要實施從(cong)原(yuan)材料入廠到成品出廠的(de)全程質(zhi)量(liang)控(kong)制(zhi)。

　　1)對(dui)原(yuan)材料的(de)(de)控制(zhi)。原(yuan)材料進(jin)場之后，閥門(men)(men)(men)生(sheng)(sheng)產(chan)(chan)(chan)企業要(yao)(yao)對(dui)其進(jin)行(xing)理化性能檢驗或(huo)復驗，確認其是否滿足生(sheng)(sheng)產(chan)(chan)(chan)閥門(men)(men)(men)的(de)(de)相關(guan)(guan)標準和(he)相關(guan)(guan)規定(ding)的(de)(de)要(yao)(yao)求。其中，與(yu)閥門(men)(men)(men)配(pei)套使用的(de)(de)法蘭、墊片(pian)等產(chan)(chan)(chan)品取得(de)與(yu)所生(sheng)(sheng)產(chan)(chan)(chan)閥門(men)(men)(men)壓(ya)力等級相一致的(de)(de)《特種設備壓(ya)力管道制(zhi)造許可證》。外包的(de)(de)閥門(men)(men)(men)生(sheng)(sheng)產(chan)(chan)(chan)企業，應制(zhi)定(ding)外程(cheng)的(de)(de)評價(jia)和(he)選擇機制(zhi)，并嚴格(ge)對(dui)外包單位實施(shi)質量控制(zhi)，其產(chan)(chan)(chan)品實現全(quan)程(cheng)受控。

　　2)鑄(zhu)造環(huan)(huan)節(jie)(jie)、熱處(chu)理和(he)焊接(jie)全程(cheng)(cheng)受控。在閥門的鑄(zhu)造環(huan)(huan)節(jie)(jie)中，應(ying)(ying)(ying)對壓鑄(zhu)機(ji)等設備的度(du)、性(xing)和(he)可(ke)用性(xing)進行(xing)機(ji)能評價以生(sheng)產正常(chang)進行(xing)。對相(xiang)關(guan)生(sheng)產人(ren)(ren)(ren)員(yuan)(yuan)要(yao)(yao)進行(xing)崗(gang)前培訓，合格或(huo)取得相(xiang)應(ying)(ying)(ying)的資格后方能上崗(gang)。其中，焊接(jie)操(cao)作人(ren)(ren)(ren)員(yuan)(yuan)應(ying)(ying)(ying)持(chi)(chi)有技術監(jian)督(du)局頒發的特(te)種設備焊接(jie)操(cao)作人(ren)(ren)(ren)員(yuan)(yuan)證書(shu)；理化(hua)試驗(yan)人(ren)(ren)(ren)員(yuan)(yuan)應(ying)(ying)(ying)持(chi)(chi)有技術監(jian)督(du)局頒發的理化(hua)試驗(yan)人(ren)(ren)(ren)員(yuan)(yuan)證書(shu)。所有持(chi)(chi)證人(ren)(ren)(ren)員(yuan)(yuan)數量(liang)應(ying)(ying)(ying)滿足相(xiang)關(guan)的法律法規的要(yao)(yao)求(qiu)(qiu)，并(bing)與企業(ye)規模相(xiang)匹配。閥門生(sheng)產企業(ye)和(he)外(wai)包單位要(yao)(yao)按(an)規范確(que)認設備、人(ren)(ren)(ren)員(yuan)(yuan)、材料、過(guo)程(cheng)(cheng)參(can)數、環(huan)(huan)境要(yao)(yao)求(qiu)(qiu)、時間要(yao)(yao)求(qiu)(qiu)、介(jie)質要(yao)(yao)求(qiu)(qiu)和(he)溫度(du)要(yao)(yao)求(qiu)(qiu)等。采(cai)用正交試驗(yan)等方法實施，確(que)定佳的工藝(yi)參(can)數，編制(zhi)出相(xiang)關(guan)的作業(ye)指(zhi)導書(shu)或(huo)操(cao)作規程(cheng)(cheng)并(bing)嚴格執(zhi)行(xing)。當各個環(huan)(huan)節(jie)(jie)的人(ren)(ren)(ren)、機(ji)、料、法、環(huan)(huan)、測等發生(sheng)變化(hua)時，應(ying)(ying)(ying)對過(guo)程(cheng)(cheng)進行(xing)再確(que)認。
