一、概述一、Sketch緊急泄放閥是安裝在儲罐上以保護儲罐及罐內(nèi)存儲物的安全裝置之一。正常工作狀態(tài)下，緊急泄放閥保持密封狀態(tài)，當出現(xiàn)緊急情況（罐槽外部暴露于火災或極端天氣變化呼吸閥正常工作無法滿足儲罐排放要求時，緊急泄放閥打開，進行緊急泄壓；當罐內(nèi)壓力急劇減小產(chǎn)生真空時，緊急泄放閥打開，迅速吸入空氣。維持罐內(nèi)正常壓力，以保護儲罐不會因壓力急聚增大或驟然減小而損壞。Theemergencypressurereliefvalveisoneofthesafetydevicesinstalledonthestoragetanktoprotectthestoragetankanditscontents.Undernormalworkingcondition,theemergencyreliefvalveremainssealed.Incaseofemergency(exposedtofireorextremeweatherchangesoutsidethetanktanktank),thebreathingvalvecannotmeettherequirementsoftankdischargewhenitworksnormally,theemergencyreliefvalvewillbeopenedforemergencyrelief;whenthepressureinthetankdecreasessharplytogeneratevacuum,theemergencyreliefvalvewillbeopenedforrapidsuctionofair.Maintainthenormalpressureinthetanktoprotectthetankfromdamageduetotherapidincreaseordecreaseofpressure.BasCo公司設計生產(chǎn)的緊急泄放閥主要分為兩大類：7100系列和7200系列：7100系列分為7110、7111、7120三種型號，7100系列僅提供安全泄放功能，無真空泄放功能。7200系列分為7210、7220兩種型號，7200系列提供安全泄放和真空泄放兩種功能。ThevalvesdesignedandmanufacturedbyBasCo?aremainlydividedintotwocategories:series7100andseries7200:Series7100isdividedintothreemodels7110、7111and7120.Series7100onlyprovidespressurerelieffunction,withoutvacuumrelieffunction.Series7200isdividedintotwomodels7210and7220.Series7200providestwofunctionsofpressurereliefandvacuumrelief.///二、安裝二、Installation安裝使用前，請務必仔細閱讀下列注意事項，確保緊急泄放閥的正確使用，以免造成人身傷害或其他安全事故。Beforeinstallationanduse,pleasereadthefollowingprecautionscarefullytoensurethecorrectuseofemergencypressurereliefvalves,soastoavoidpersonalinjuryorothersafetyaccidents.1緊急泄放閥為安全裝置，必須由專業(yè)的維修技術人員進行維護，且在安裝或維護本產(chǎn)品之前，請仔細閱讀并理解本手冊。Emergencypressurereliefvalvesaresafetydevices,whichmustbemaintainedbyprofessionalmaintenancetechnicians.Pleasereadandunderstandthismanualcarefullybeforeinstallingormaintaining.2安裝前請確保安裝環(huán)境是安全的，做好防護措施，保護好眼睛、口鼻、皮膚等部位，保證人員安全。Beforeinstallation,pleaseensurethattheinstallationenvironmentissafe,takeprotectivemeasures,protecteyes,nose,skinandotherparts,andensurethesafetyofpersonnel.3改裝設備如需動火，必須由相關持證人員操作。Ifhotworkisneededfortherefittedequipment,itmustbeoperatedbyrelevantpersonnelwithcertificate.4吊裝設備應穩(wěn)定可靠。Thehoistingequipmentshallbestableandreliable.5如需高空作業(yè)，請做好防護措施。Ifyouneedtoworkatheight,pleasetakeprotectivemeasures.6檢查緊急泄放閥的銘牌是否與所要安裝的產(chǎn)品一致，若有誤，請及時與BasCo公司聯(lián)Checkwhetherthenameplateofthevalveisconsistentwiththeproducttobeinstalled.Ifthereisanyerror,pleasecontactBasco?intime.7確?，F(xiàn)場設備足夠支撐緊急泄放閥的重量，如有必要，需安裝支撐裝置。Ensurethatthefieldequipmentisadequatetosupporttheweightofthevalve,andinstallsupportingdevicesifnecessary.(1)拆除緊急泄放閥內(nèi)外的所有保護包裝材料。Removeanddiscardallprotectivepackagingmaterialfromonorinsidethevalve.(2)出廠時緊急泄放閥已裝配完成，可直接安裝，在安裝之前，無需進行調(diào)整或修改。Thevalvehasbeenassembledatthefactoryandcanbeinstalleddirectlywithoutadjustmentormodificationbeforebeinginstalled.(3)檢查裝配法蘭的密封面，必須清潔、平整，無劃痕、腐蝕，且密封墊片材料適合應用。Checkthesealingsurfaceoftheassemblyflange,whichmustbeclean,flat,freeofscratchesandcorrosion,andthesealinggasketmaterialissuitableforapplication.(4)用適當?shù)穆菁y潤滑劑潤滑所有緊固件，如果緊急泄放閥在高溫環(huán)境下使用或使用不銹鋼緊固件，請選擇防卡死型化合物潤滑劑。Lubricateallfastenerswithappropriatethreadlubricant.Ifthevalveisusedinhightemperatureenvironmentorstainlesssteelfastenersareused,pleaseselectantiseizecompoundlubricant.(5)采用適當?shù)牡跹b方式將緊急泄放閥安裝到儲罐法蘭上。注：為了獲得最好的性能，緊急泄放閥應水平安裝，確保閥盤組件可以自由打開。用手預擰緊緊固件，確保密封面被均勻壓縮之后，用扭矩扳手交替均勻地擰緊所有緊固件。Mountthevalvetothetankflangewithcorrecthoistingmethod.NOTE:Forbestperformance,thevalveshouldbemountedlevel,makesurethatthevalvediscassemblyisfreetohingeopenandtoreclose.Pretightenthefastenersbyhand,afterensuringthatthesealingsurfaceisevenlycompressed,tightenallfastenersalternatelyandevenlywithatorquewrench.(6)安裝完成后，必須檢查所有連接是否密封良好，緊固件是否有松動，連接處是否有氣體（蒸氣）泄露。Afterinstallation,itisnecessarytocheckwhetherallconnectionsarewellsealed,whetherfastenersareloose,andwhetherthereisgas(vapor)leakageattheconnection.(1)拆除緊急泄放閥內(nèi)外的所有保護包裝材料。Removeanddiscardallprotectivepackagingmaterialfromonorinsidethevalve.(2)出廠時緊急泄放閥已裝配完成，可直接安裝，在安裝之前，無需進行調(diào)整或修改。Thevalvehasbeenassembledatthefactoryandcanbeinstalleddirectlywithoutadjustmentormodificationbeforebeinginstalled.(3)檢查裝配法蘭的密封面，必須清潔、平整，無劃痕、腐蝕，且密封墊片材料適合應用。Checkthesealingsurfaceoftheassemblyflange,whichmustbeclean,flat,freeofscratchesandcorrosion,andthesealinggasketmaterialissuitableforapplication.(4)用適當?shù)穆菁y潤滑劑潤滑所有緊固件，如果緊急泄放閥在高溫環(huán)境下使用或使用不銹鋼緊固件，請選擇防卡死型化合物潤滑劑。Lubricateallfastenerswithappropriatethreadlubricant.Ifthevalveisusedinhightemperatureenvironmentorstainlesssteelfastenersareused,pleaseselectantiseizecompoundlubricant.(5)采用適當?shù)牡跹b方式將緊急泄放閥安裝到儲罐法蘭上。用手預擰緊緊固件，確保密封面被均勻壓縮之后，用扭矩扳手交替均勻地擰緊所有緊固件。Mountthevalvetothetankflangewithcorrecthoistingmethod.Pretightenthefastenersbyhand,afterensuringthatthesealingsurfaceisevenlycompressed,tightenallfastenersalternatelyandevenlywithatorquewrench.注1：為了獲得最好的性能，緊急泄放閥應水平安裝，確保閥盤組件可以自由打開。注2:彈簧組件為預壓縮部件，出廠時已按要求調(diào)校完畢。安裝時，請注意保持導桿的平行度，不得有影響產(chǎn)品正常開啟的阻礙。如現(xiàn)場工況需要重新調(diào)整彈簧壓縮量，請預先通知廠家，協(xié)商后方可施工。NOTE1:Forbestperformance,thevalveshouldbemountedlevel,makesurethattheva
