Ama-flange yizinto zokufakwa kwamapayipi ezivame ukusetshenziselwa ukuxhuma amapayipi namapayipi noma ukuxhuma izinto ezimbili ohlelweni lwamapayipi.Kunezinhlobo eziningi zeama-flange,njengeama-flanges anemicu, welding intamo flanges, ipuleti welding flanges, njll. (ngokuhlangene kubizwa ngokuthi ama-flange).Kodwa-ke, empilweni yangempela, ungaqaphela futhi ukuthi kukhona omunye umkhiqizo we-flange obizwa ngokuthi i-blind flange.Uyini umehluko phakathi kwe-flange evamile ne-blind flange?Indlela yokufaka nokusebenzisa i-blind flange?
1. Umehluko phakathi kwe-flange ne-blind flange
(1) Kunezimbobo ku-flange.Ngesikhathi sokuxhuma, ama-flange amabili adinga ukuboshwa ngama-bolts.I-flange ivalwe ngama-gaskets ukuze idlale indima yokuvala, noma idlale indima yesikhashana ekuhlolweni;
I-flange eyimpumputhe yakhiwe ngokusakazwa noma uxhumano olunentambo noma i-welding.Kuyi-flange engenazimbobo phakathi.Isetshenziselwa ikakhulukazi ukuvala ukuphela kwepayipi, nokuvala i-orifice yepayipi.Umsebenzi wayo ufana nowekhanda kanye nesembozo sepayipi, futhi idlala indima yokuhlukanisa ukudlidliza nokusika.Nokho, i-blind flange seal iyithuluzi lokuvala elikhiphekayo.Uphawu lwekhanda alukalungeli ukuvulwa futhi.I-flange eyimpumputhe ingasuswa ukuze kube lula ukusetshenziswa kabusha kwepayipi esikhathini esizayo.
(2) Ngenxa yokuthi i-flange inezici zokusebenza ezinhle, ivame ukusetshenziswa kakhulu kubunjiniyela bamakhemikhali, ukwakhiwa, uphethiloli, ukukhucululwa kwendle, amapayipi, ukuvikela umlilo kanye namanye amaphrojekthi ayisisekelo;
Kuyadingeka ukusetha amapuleti ayimpumputhe ekuxhumekeni kwemishini kanye nepayipi, ikakhulukazi endaweni yomngcele ngaphandle kwendawo yomngcele lapho amapayipi ezinto ezihlukahlukene zenqubo axhunyiwe.Kodwa-ke, ekuhlolweni kwamandla epayipi noma ukuhlolwa kokuvala uphawu, akuvunyelwe ukusebenzisa amapuleti angaboni ngesikhathi esifanayo nempahla yokuxhuma (njenge-turbine, compressor, gasifier, reactor, njll.) esigabeni sokuqala sokulungiselela ukuqalisa.
Kodwa empeleni, kukhona ukufana okuningi phakathi kwama-flange namapuleti ayimpumputhe e-flange.Isibonelo, kunezinhlobo eziningi zezindawo zokuvala, njengendiza, i-convex, i-concave ne-convex, i-tenon ne-groove, nezindawo zokuxhuma indandatho;Isetshenziselwa uxhumano lwe-flange, ehlanganisa i-pair of flanges, i-gasket nama-bolts amaningana namantongomane.I-gasket ibekwe phakathi kwezindawo ezimbili zokuvala ama-flange.Ngemva kokuqinisa i-nati, ingcindezi ethile endaweni ye-gasket ifinyelela inani elithile, elizobangela ukuguqulwa, futhi izingxenye ezingalingani endaweni yokubeka uphawu zizogcwaliswa ukuze uxhumano luqine.
2. Ukufakwa kanye nokusetshenziswa flange blind plate
Ipuleti eliyimpumputhe le-flange lingaxhunywa futhi nge-flange, okungukuthi, i-gasket ibekwe phakathi kwezindawo ezimbili zokuvala ama-flange.Ngemuva kokuthi i-nut iqinisiwe, ingcindezi ethile ebusweni be-gasket ifinyelela inani elithile, futhi ukuguqulwa kwenzeka, futhi izindawo ezingalingani endaweni yokubeka uphawu zigcwele, ukuze uxhumano luqine.Kodwa-ke, ipuleti eliyimpumputhe le-flange elinengcindezi ehlukene linogqinsi oluhlukile futhi lisebenzisa amabhawodi ahlukene;Endabeni yesistimu ye-oil medium, ipuleti eliyimpumputhe le-flange alidingi ukufakwa uthayela, kodwa esimweni sezinye izinhlelo eziphakathi, ipuleti eliyimpumputhe le-flange lizobhekana nokwelashwa okushisayo kwe-galvanizing, isisindo esincane se-zinc coating singama-610g / m2. , kanye nekhwalithi yepuleti eliyimpumputhe le-flange ngemva kokufakwa uthayela oshisayo lizohlolwa ngokwezinga likazwelonke.
Okungenhla umehluko phakathi kwe-flange ne-blind flange kanye nokufakwa nokusetshenziswa kwe-blind flange.Ngethemba ukuthi ingakusiza ukuthi ukhethe futhi ufake i-flange ngendlela efanele futhi udlale indima yayo yokuvala.
