Iziyalezo zokufakwa kwama-valve amabhola ane-flanged Izidingo zobuchwepheshe zokufakwa nokusetshenziswa kwamavalvu egesi anoketshezi

Iziyalezo zokufakwa kwama-valve ebhola ane-flanged Izidingo zobuchwepheshe zokufakwa nokusetshenziswa kwama-valve egesi anoketshezi 1. I-perpendicularity yendawo ye-flange epayipini kanye nomugqa omaphakathi wepayipi kanye nephutha lembobo yebhawodi ye-flange kufanele ibe phakathi kobubanzi obuvunyelwe. inani. Ivalvu kanye nolayini wesikhungo samapayipi kufanele kuhambisane ngaphambi kokufakwa. 2. Uma ubopha amabhawodi, sebenzisa isikrufu esifana namantongomane. Lapho usebenzisa ingcindezi kawoyela namathuluzi womoya wokubopha, qaphela ukuthi ungadluli itorque eshiwo. 3. Uma uxhuma ama-flange amabili, okokuqala, i-flange yokuvala uphawu kanye ne-gasket kufanele icindezelwe ngokulinganayo, ukuze kuqinisekiswe ukuthi i-flange ixhunywe ukucindezeleka okufanayo kwe-bolt. 4. Ukuqiniswa kwe-flange kufanele kugweme amandla angalingani, futhi kufanele kuqiniswe ngokuhambisana nesiqondiso se-symmetry ne-intersection. 5. Ngemuva kokufakwa kwe-flange, qinisekisa ukuthi wonke ama-bolts namantongomane aboshwe ngokulinganayo. 6, ukuqiniswa kwamabhawodi namantongomane, ukuze kuvinjelwe ukuxega okubangelwa ukudlidliza, ukusebenzisa amawasha. Ukuze ugweme ukunamathela phakathi kwezintambo ekushiseni okuphezulu, izingxenye zentambo kufanele ziboshwe nge-anti-adhesion agent ngesikhathi sokufakwa. 7. Isetshenziselwa ama-valve okushisa aphezulu angaphezu kuka-300℃. Ngemva kokwenyuka kwezinga lokushisa, amabhawodi okuxhuma ama-flange, amabhawodi okubopha ama-valve ekhava, ama-pressure seals nama-packing bolts we-gland kumele aqiniswe futhi. I-8, i-valve yokushisa ephansi ifakwe esimweni sokushisa komkhathi, ngenxa yokwakheka komehluko wokushisa, i-flange, i-gasket, ama-bolts namantongomane ayancipha, futhi ngenxa yokuthi izinto zalezi zingxenye azifani 9, i-coefficient yokwandisa yomugqa futhi ezahlukene, ukwakha lula kakhulu ukuvuza izimo zemvelo. Kusukela kulesi simo senhloso, lapho kuqinisa ama-bolts ekushiseni komkhathi, i-torque ecabangela izici zokunciphisa ingxenye ngayinye ekushiseni okuphansi kufanele yamukelwe. 1. Ngaphambi kokufakwa, i-valve yangaphakathi ye-LPG kufanele ihlanzwe futhi iziphambeko ezibangelwa ukuthutha kufanele zisuswe; 2. Ukufakwa kwevalve ye-LPG kufanele kugcine i-valve ye-butterfly drive shaft ivundlile kanye ne-piston valve ibheke phezulu; 3. Ngaphambi kokusebenzisa i-valve ye-LPG, idivayisi yokudlulisela kufanele ilungiswe ukuze kugcinwe imisebenzi yedivayisi yokudlulisela ingaguquki, futhi umkhawulo wokushaya kanye nokulawula ukuvikela i-torque ngaphezulu kunokwethenjelwa; 4. Amafutha okugcoba kufanele engezwe ngokugcwele ngaphambi kokugunyazwa nokusetshenziswa kwengxenye ngayinye yokuthambisa yedivayisi yokudlulisa ivalvu ye-LPG; 5. Ngaphambi kokuqala idivayisi kagesi, imanuwali yedivayisi kagesi ye-valve yegesi ewuketshezi kufanele ifundwe ngokucophelela.
