Nta
A42Y txais tag nrho - lub kaus mom lub kaus mom tsim nrog tsis muaj phau ntawv xeem qib. Txhua qhov kev pab cuam nruab nrab yog coj mus rau qhov hluav taws xob tawm piping; tsis muaj volatile los yog teeb meem nruab nrab khiav tawm mus rau huab cua. Tiv thaiv plua plav thiab noo noo nkag mus rau hauv lub caij nplooj ntoos hlav sab hauv. Kev tsim kho yooj yim rau qhov chaw uas phau ntawv ntawm - qhov chaw nqa nqa tsis tas yuav tsum tau ua.
Ua-rov qab- tshuab-disc los ua ke. Thaum ncav cuag - siab, valve pops qhib tam sim nrog nqa Ntau dua lossis sib npaug rau 1/4 nozzle txoj kab uas hla rau loj - muaj peev xwm nyem. Adjustable nozzle nplhaib tso cai rau tshuab -down tuning. Kev ua haujlwm tawm tau ua raws li API-520 cov txheej txheem muaj peev xwm, zoo heev rau kev pabcuam roj compressible thiab hydrocarbon.
Nozzle thiab disc lub rooj zaum lub ntsej muag nyuaj - ntsib nrog Stellite cobalt - puag alloy. Kev tiv thaiv siab tiv thaiv yaig thiab hnav hauv kev ua haujlwm cyclic nyem. Lub rooj zaum nruj raws li API-527 tus qauv xau, txo lub rooj zaum-seepage kev pheej hmoo rau hydrocarbon thiab volatile-gas daim ntawv thov.
Lub caij nplooj ntoos hlav ntshiab-tsav tsim yam tsis muaj hluav taws xob sab nraud. Teem -siab adjustable ntawm -site. Tsis siv neeg qhib thaum tshaj -siab; nruj re- zaum thaum lub siab poob los tshuab- nqes qis. Cov lus ceeb toom tseem ceeb: qhov no tsis yog -bellows hom pa. Fluctuating superimposed rov qab-siab yuav cuam tshuam rau kev teeb tsa-siab thiab rov- rooj zaum ua haujlwm. Xaiv WA42Y bellows- sib npaug version rau qhov sib txawv rov qab - cov xwm txheej siab.
WCB carbon steel rau dav dav -lub hom phiaj roj-hydrocarbon kev pabcuam; CF8 / CF8M stainless hlau rau corrosive kua. NACE-MR0175 wetted trim tuaj yeem txiav txim siab tshwj xeeb rau kev ntub dej -H₂S qaub- kev pabcuam. Muaj rau GB PN lossis ASME B16.5 phaus -qib flange.
Yam khoom siv
- Petrochemical siab hlab ntsha, hydrocarbon cia tank thiab cais
- LPG, roj av- roj thiab volatile - nruab nrab txheej txheem piping system
- Cov cuab yeej siv siab uas yuav tsum tau kaw tawm yam tsis muaj phau ntawv qhia - qib ntsuas
- Tshuaj tsob nroj tshaj - kev tiv thaiv siab rau compressible roj nruab nrab
Txoj Cai Ua Haujlwm & Daim Ntawv Thov
Kaw lub kaus mom Tag Nrho Kev Nyab Xeeb Kev Nyab Xeeb raug kaw - lub kaus mom puv - nqa lub caij nplooj ntoo hlav - ntsaws ruaj ntseg valve yam tsis muaj phau ntawv tuav. Nyob rau hauv ib txwm ua haujlwm siab, lub caij nplooj ntoos hlav quab yuam tuav disc ruaj khov rau lub rooj zaum nozzle. Thaum lub zog siab nce los teeb tsa - siab, nruab nrab thrust overcomes caij nplooj ntoos hlav preload; rov qab- tshuab-disc tsim kom muaj zog nqa ntxiv thiab valve pops qhib rau loj- muaj peev xwm decompression. Thaum lub siab poob rau tshuab-tus nqi pib dua, lub caij nplooj ntoos hlav thawb lub disc rov qab rau hauv qhov chaw zaum kom kaw nruj- tawm. Tsis yog -bellows pa siv, hloov pauv rov qab-siab yuav ua rau teeb tsa-siab drift; xaiv WA42Y bellows- qauv sib npaug rau qhov hloov pauv rov qab- siab.Closed bonnet Full lift Safety Valve tsis haum rau H₂S-muaj qaub- kev pabcuam tshwj tsis yog NACE-cov ntaub ntawv hloov kho raws li tau teev tseg. Muab cov txheej txheem -siab, kev khiav hauj lwm kub, nruab nrab cov cuab yeej thiab yuav tsum tau nyem- muaj peev xwm kom raug sizing ua ntej kev txiav txim.
