Lub flange yog ib qho kev sib txuas los yog ntug ntawm cov yeeb nkab, lub valve, los yog lwm yam khoom, feem ntau yog siv los ua kom muaj zog los yog pab txhawb kev txuas ntawm cov kav dej los yog fittings.
Flange tseem hu ua flange convex disk lossis convex phaj. Nws yog ib qho disk-puab qhov chaw, feem ntau yog siv hauv khub.Nws yog siv los ntawm cov yeeb nkab thiab lub valve, nruab nrab ntawm cov yeeb nkab thiab cov yeeb nkab thiab nruab nrab ntawm cov yeeb nkab thiab cov khoom siv, thiab lwm yam. Nws yog cov khoom sib txuas nrog cov nyhuv sealing. Muaj ntau daim ntawv thov ntawm cov khoom siv thiab cov kav dej, yog li ob lub dav hlau txuas nrog bolts, thiab cov khoom sib txuas nrog cov nyhuv sealing hu ua flange.
Flanges feem ntau yog siv rau hauv cov kav dej los txuas cov kav dej, li qub, twj, thiab lwm yam khoom siv. Lawv muab ib txoj hauv kev yooj yim rau kev sib dhos thiab disassembly ntawm cov khoom, nrog rau kev tshuaj xyuas, hloov kho, lossis tu lub system.
Feem ntau, muaj qhov puag ncig ntawm lub flange los ua lub luag haujlwm ruaj khov. Piv txwv li, thaum siv ntawm cov yeeb nkab sib txuas, lub nplhaib sib khi yog ntxiv ntawm ob lub phaj flange. Thiab tom qab ntawd qhov kev sib txuas yog nruj nrog bolts. Lub flange nrog lub siab sib txawv muaj qhov sib txawv thickness thiab txawv bolts. Cov ntaub ntawv tseem ceeb siv rau flange yog carbon steel, stainless hlau thiab hlau alloy, thiab lwm yam.
Muaj ob peb homflanges, txhua tus tsim rau lub hom phiaj tshwj xeeb. Nov yog qee hom flanges:
- Weld Neck Flange (WN):Hom flange no yog tus cwj pwm los ntawm lub caj dab ntev, tapered caj dab uas yog welded rau cov yeeb nkab. Nws yog tsim los hloov kev ntxhov siab los ntawm flange mus rau cov yeeb nkab, txo qhov kev pheej hmoo ntawm kev xau.Weld caj dab flangesfeem ntau yog siv nyob rau hauv high-pressure thiab high-temperature daim ntaub ntawv.
- Slip-On Flange (SO): Npuag-on flangesmuaj ib txoj kab uas hla me ntsis loj dua cov yeeb nkab, thiab lawv tau hla cov yeeb nkab thiab ces welded rau hauv qhov chaw. Lawv yooj yim dua los ua kom haum thiab haum rau cov ntawv thov uas tsis tshua muaj siab. Muaj lwm hom flange zoo ib yam li nws, hu ua phaj flange. Qhov sib txawv ntawm ob qhov lus dag nyob rau hauv lub xub ntiag los yog tsis muaj lub caj dab, uas yuav tsum tau nruj me ntsis txawv.
- Qhov muag tsis pom Flange (BL): Qhov muag tsis pom flangesyog cov khoom siv uas siv los thaiv cov yeeb nkab lossis los tsim qhov nres ntawm qhov kawg ntawm cov kav dej. Lawv tsis muaj qhov chaw nruab nrab thiab siv los kaw qhov kawg ntawm cov kav dej.
- Qhov (socket) Weld Flange (SW): Qhov (socket) weld flangesmuaj lub qhov (socket) lossis poj niam kawg uas yog siv los txais cov yeeb nkab. Cov yeeb nkab yog muab tso rau hauv lub qhov (socket) thiab ces welded nyob rau hauv qhov chaw. Lawv yog siv rau cov kav dej me me thiab cov ntawv thov siab.
- Threaded Flange (TH): Threaded flangesmuaj xov nyob rau sab hauv, thiab lawv siv nrog cov kav dej uas muaj cov xov sab nraud. Lawv haum rau cov ntawv thov uas tsis tshua muaj siab.
- Lap Joint Flange (LJ): Lap sib koom flangesyog siv nrog ib tug stub kawg los yog ib tug ncej puab nplhaib. Lub flange yog txav mus los ntawm cov yeeb nkab thiab tom qab ntawd lub qhov kawg lossis lub nplhaib sib koom ua ke yog welded rau cov yeeb nkab. Hom flange no tso cai rau kev sib dhos yooj yim ntawm lub qhov ntsia hlau.
