Yenziwe ngentsimbi eshayinayoiflangeyinxalenye ebalulekileyo yomsebenzi wokudibanisa umbhobho, iintlobo ezininzi, umgangatho unzima. Ngenxa yokuxhathisa okuqinileyo komhlwa kunye nokumelana nomhlwa, idlala indima yokudibanisa kumbhobho. Ngoko ke, uphawu oluphambili lwe-flange yensimbi engenasici yindlela yokudibanisa kunye nendlela yokutywinwa, i-parameter yempembelelo yingcinezelo yombhobho.
Ngokuqhelekileyo, inkqubo yoxinzelelo oluphantsi (PN <2.5MPA) isebenzisa i-welding flat okanyeipleyiti yentsimbi yeflange ukutywinaumphezulu(RF) itywina; Inkqubo yoxinzelelo oluphakathi (2.5-64MPA) ithatha i-butt welded steel stainless flange, i-RF okanye i-concave-convex surface (FM / M) itywina; Iinkqubo zoxinzelelo oluphezulu (10.0MPA okanye ngaphezulu) zihlala zisebenzisa i-buttweldingsteel stainless flanged ladder groove (RJ) ukutywinwa. Kwinkqubo yoxinzelelo oluphantsi lwensimbi engenasici, ngamanye amaxesha ukuze kugcinwe iindleko kunye nokugcinwa okufanelekileyo, kuya kuphinda kukhethe i-flange yensimbi engenasici okanye i-ring stainless steel flange ring.
Ukusetyenziswa kunye neendlela zokulondoloza:
1. Ukugcinwa kwexesha elide le-flange yensimbi engenasici, kufuneka igcinwe rhoqo, ihlala ivulekele ngaphandle kwemveliso kunye nomgangatho wokucubungula kufuneka igcinwe icocekile, isuse amabala, igcinwe kakuhle kwindawo eyomileyo kunye ne-manetic yendalo, ukupakishwa okungavumelekanga okanye ngaphandle. yokugcina. Ukugcina i-flange yensimbi eyomileyo kunye ne-ventilation yendalo, i-transparent retainer icocekile kwaye icocekile, ngokuhambelana nendlela efanelekileyo yokugcina.
2. Ngaphambi kokufakela, qiniseka ukuba uhlolisise inkcazo nganye kunye nobukhulu be-flange yensimbi engenasici: ingaba ububanzi bombhobho buhambelana nemimiselo yesicelo, susa iintsilelo ezibangelwa yinkqubo yokuthutha, kwaye ususe amabala e-flange yensimbi engenasici, yenza kakuhle. Ukulungiselela kwangaphambili ngaphambi kokufaka, yonke into ilungile.
3. Ngethuba lofakelo, i-flange yensimbi engenasici inokufakwa ngokukhawuleza kwipayipi ngokwemowudi ye-interface, kwaye ukufakela kunokwenziwa ngokwendawo yesicelo. Ngokuqhelekileyo, inokufakwa kuyo nayiphi na inxalenye yombhobho, kodwa kufuneka ihambisane nokugcinwa komsebenzi wangempela. Nika ingqalelo ekungeneni kwezinto ze-flange yensimbi engenasici kufuneka ibe yi-disc ye-valve longitudinal phantsi kosaziwayo, kunye ne-flange yensimbi engenasici kufakelo oluthe tye kuphela. I-flange yensimbi engenasici ekufakeni kufuneka ihlawule ingqalelo kwi-tightness, ukuphepha ukuvuza, ukulimaza konke ukusebenza okuqhelekileyo kombhobho.
4. I-valve yesango ye-flange yensimbi engenasici, i-valve yokumisa, i-valve yokumisa i-valve, kuphela i-valve evulekileyo evulekileyo okanye egcweleyo, ayivumelekanga ukulungelelanisa ukuhamba okupheleleyo, ukwenzela ukuthintela ukukhukuliseka komphezulu, ukukhawuleza umonakalo. I-valve yokumisa kunye ne-valve yokumisa intambo yangaphandle ephezulu inezixhobo zokutywina eziguquliweyo, kwaye isibambo siqiniswe kwindawo ephezulu ukukhusela izinto eziphuma kwizinto zokuzalisa.
Indlela yokunyangwa kwentsimbi engenastainless flange corrosion:
1. Coca ngelaphu le-emery kunye nebrashi yocingo.
2. Sebenzisa ifosholo yensimbi ye-tungsten ukususa iindawo ezinkulu zomhlwa.
3. Susa iiprotrusions ezifana ne-welding slag kunye ne-burrs eyahlukeneyo ngefayile.
4. Susa umhlwa kwiikona nge-scraper kunye nebrashi yocingo.
5. Coca nge-rag ecocekileyo, okanye udibanise kwi-solvent rag primer ngexesha.
6. Nika ingqalelo kwi-coating toughness ayiphumelelanga, inokugcinwa. Sebenzisa ilaphu le-emery ukugquma umphezulu wepeyinti endala, isanti iziphene zokugquma zibe yimo yezembe, kwaye upeyinte ngqo emva kokucoca.
