Koj yuav pom lub cev valve nyob nruab nrab ntawm cov yeeb nkab flanges vim nws tuav cov khoom valve rau hauv qhov chaw. Cov khoom siv lub cev valve yog hlau thiab ua los ntawm cov hlau carbon, stainless hlau, titanium alloy, nickel alloy, lossis aluminium bronze. Txhua yam tshwj tsis yog carbon steel yog tsim rau cov chaw muaj xeb.
Lub cev rau lub valve tswj npauj npaim feem ntau yog hom lug, hom wafer, lossis ob chav flanged.
- Lug
- Cov lugs uas tawm los uas muaj cov qhov bolt kom phim nrog cov nyob rau hauv lub yeeb nkab flange.
- Tso cai rau kev pabcuam tuag lossis kev tshem tawm cov kav dej hauv qab.
- Cov ntsia hlau uas muaj xov ncig thoob plaws thaj chaw ua rau nws yog qhov kev xaiv zoo dua.
- Muab kev pabcuam kawg ntawm kab.
- Cov xov tsis muaj zog txhais tau tias qhov ntsuas torque qis dua
- Ncuav mog qab zib
- Tsis muaj cov lugs tawm thiab hloov chaw yog sandwiched ntawm cov yeeb nkab flanges nrog flange bolts nyob ib puag ncig lub cev. Muaj ob lossis ntau lub qhov nyob hauv nruab nrab los pab nrog kev teeb tsa.
- Tsis hloov qhov hnyav ntawm lub raj xa dej los ntawm lub cev valve ncaj qha.
- Sib dua thiab pheej yig dua.
- Cov qauv wafer tsis hloov qhov hnyav ntawm lub raj xa dej ncaj qha los ntawm lub cev valve.
- Tsis siv tau ua qhov kawg ntawm cov yeeb nkab.
- Ob chav flanged
- Ua kom tiav cov flanges ntawm ob qho kawg kom txuas nrog cov yeeb nkab flanges (flange ntsej muag ntawm ob sab ntawm lub valve).
- Nrov rau cov li qub loj.
