Kungakanani okwaziyo ngama-blind flange?

Ama-blind flange ayizingxenye ezibalulekile ezinhlelweni zamapayipi ezisetshenziselwa ukuvala ukuphela kwepayipi, i-valve, noma ukuvulwa komkhumbi ocindezelayo.Ama-blind flange angama-plate-like discs angenayo i-centre bore, okuwenza alungele ukuvala ukuphela kwesistimu yamapayipi.umbukwane blindemsebenzini kanye nesimo.

Isingeniso Somkhiqizo

Ama-blind flange enziwa ngezinto ezahlukene, kuye ngezidingo ezithile zohlelo lokusebenza.Izinto ezifana nensimbi engagqwali, i-carbon steel, ne-alloy steel zivame ukusetshenziswa.Ama-flange aklanyelwe ukufanela amasistimu amapayipi anezingcindezi ezihlukene, osayizi, namazinga okushisa.Kunezinhlobo ezahlukene zama-blind flange, okuhlanganisa ama-blind blind flanges aphakanyisiwe, ama-blind type joint (RTJ) blind flanges, kanye nama-blind blind flange.Ukukhethwa kwe-blind flange ongayisebenzisa kuncike ezidingweni zohlelo lokusebenza.

Imininingwane namamodeli

Ama-blind flange afika ngokucaciswa okuhlukile namamodeli, ngayinye yakhelwe ukuhlangabezana nezidingo ezihlukile zohlelo lokusebenza.Atholakala ngosayizi abahlukahlukene, kusukela ku-1/2" kuya ku-48" kuma-blind blind flanges kanye no-1/2" kuya ku-24" we-RTJ.izimpumputhe flange.Ubukhulu be-flange buyahlukahluka, futhi, nobukhulu obujwayelekile obusuka ku-1/4 "kuya ku-1", kuyilapho ubukhulu bepayipi elimnyama eliyimpumputhe busukela ku-2"-24".Amamodeli e-flange afika ku-Class 150 kuya ku-Class 2500, PN6 kuya ku-PN64 isilinganiso sokucindezela, kanye namazinga we-ASME/ANSI B16.5, ASME/ANSI B16.47, API, kanye ne-MSS SP44.

Umsebenzi kanye nezigaba

Uma kubonwa ngokubukeka, ipuleti eliyimpumputhe livamise ukuhlukaniswa libe yipuleti eliyi-flat plate blind plate, i-spectacle blind plate, ipulaki lepulaki neringi yokusekela (ipulaki neringi yokusekela ayiboni ndawo).Ipuleti eliyimpumputhe lidlala indima efanayo yokuhlukaniswa nokusika njengekhanda, isivalo sepayipi kanye nepulaki yokushisela.Ngenxa yokusebenza kwayo okuhle kokuvala, imvamisa isetshenziswa njengendlela ethembekile yokuzihlukanisa kumasistimu adinga ukuhlukaniswa okuphelele.Ipuleti yohlobo lwe-flat blind plate iyindilinga eqinile enesibambo, esetshenziselwa uhlelo esimweni sokuzihlukanisa ngaphansi kwezimo ezivamile.Impumputhe yombukwane imise okwempumputhe yokubukwa.Omunye umkhawulo uyipuleti eliyimpumputhe kanti omunye umkhawulo uyindandatho ye-throttling, kodwa ububanzi bufana nobubanzi bepayipi futhi alidlali indima ye-throttling.Ipuleti eliyimpumputhe le-spectacle kulula ukuyisebenzisa.Uma ukuhlukaniswa kuyadingeka, sebenzisa i-blind plate end.Uma umsebenzi ojwayelekile udingeka, sebenzisa i-throttling ring end.Ingase futhi isetshenziselwe ukugcwalisa igebe lokufakwa kwepuleti eliyimpumputhe epayipini.Esinye isici ukuhlonza okusobala futhi kulula ukuhlonza isimo sokufakwa

Ukuqhathanisa Nemikhiqizo Efanayo

Ama-blind flange ayindlela engcono yokuvala kuneminye imikhiqizo yokuvala.Ziqinile futhi zihlala isikhathi eside kunama-gaskets, angaguga ngokuhamba kwesikhathi.Ama-blind flange nawo anokwethenjelwa kakhulu kunama-flange omzimba aboshwe, adinga ukuqina nokuqina ukuze kuvinjelwe ukuvuza.Ama-blind flange anikeza uphawu oluhlala njalo futhi adinga ukulungiswa okuncane, okwenza kube inketho engabizi ngokuhamba kwesikhathi.

Sengiphetha, ama-flange ayizimpumputhe ayizingxenye ezibalulekile ezinhlelweni zamapayipi, ezisetshenziselwa ukuvala ukuphela kwepayipi noma ukuvulwa kwe-valve.Zenziwe ngezinto ezihlukene futhi ziza ngobukhulu obuhlukene, ukucaciswa, namamodeli, okuzenza zilungele ukusetshenziswa okuhlukahlukene.Ama-flange athembekile, aqinile, futhi adinga ukulungiswa okuncane, okuwenza abe yinketho engabizi ngokuhamba kwesikhathi.Ama-blind flange ayindlela engcono yokuvala kunama-gaskets nama-flange omzimba aboshwe futhi anikeza uphawu oluhlala njalo ukuvimbela ukuvuza.Uma udinga umphakeli we-blind flange othembekile nothembekile, sicabangele.Sinohlu olubanzi lwama-blind flange ahlangabezana nezindinganiso zekhwalithi ephezulu kakhulu, okuqinisekisa ukuphepha nokwethembeka kwesistimu yakho yamapayipi.
