Dab tsi yog Flange Kev Txuas?
Kev sib txuas flange yog ib txoj hauv kev siv los txuas ob lub kav dej, cov yeeb nkab fittings, lossis cov khoom siv los ntawm kev kho lawv mus rau flanges. Cov flanges tom qab ntawd tau koom ua ke siv cov bolts, nrog lub gasket muab tso rau nruab nrab ntawm lawv kom muaj kev ruaj ntseg thiab tsis muaj kev sib txuas. Qee qhov fittings thiab khoom siv tuaj nrog lawv tus kheej flanges ua ntej txuas, ua cov txheej txheem ncaj nraim. Peb tsis tsuas yog muabkav, raj, phaj, ntawv, round bar, tab sis kujfabricated yeeb nkab spoolskev pabcuam.
Hom Flange Connections
1. Hom Flange Connections: Threaded (Wire Connection) Flange
- Nqe lus piav qhia: Cov yeeb nkab yog screwed rau hauv flange.
- Kev Siv: Haum rau cov ntawv thov uas tsis tshua muaj siab thiab me me.
- Qhov zoo: Yooj yim rau nruab thiab tshem tawm yam tsis muaj vuam.
2. Hom Flange Connections: Welded Flange
- Nqe lus piav qhia: Cov yeeb nkab yog welded rau flange, muab kev sib txuas zoo dua.
- Kev Siv: Siv rau kev siv siab thiab loj-ntev.
- Qhov zoo: Muab kev ruaj ntseg thiab ruaj khov kev sib txuas muaj peev xwm tiv taus kev kub ntxhov.
Flange Pads (Gaskets)
Cov khoom ntawm lub gasket muab tso rau ntawm flanges nyob ntawm lub siab thiab cov kua dej thauj:
- Tsawg Siab: Cov ntaub qhwv asbestos feem ntau yog siv.
- High Pressure: High-pressure asbestos pads lossis hlau pads yog siv.
Cov ntawv thov kev lag luam
Flange kev sib txuas yog siv dav hauv kev lag luam piping systems vim lawv txoj kev ntseeg siab thiab kev saib xyuas yooj yim. Lawv tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas cov yeeb nkab txoj kab uas hla yog loj, thiab lub siab yog siab, xws li:
- Chav boiler:Cov kav dej flangedthiab cov cuab yeej siv tau ntau vim yog lub tshuab hluav taws xob siab.
- Cov Chaw Tsim Khoom: Flange kev sib txuas yog ubiquitous nyob rau hauv kev lag luam chaw, kom muaj kev ruaj ntseg thiab ruaj ntseg kev sib txuas nyob rau hauv complex piping systems.
International Flange Standard Systems
Muaj ob lub hauv paus thoob ntiaj teb rau cov yeeb nkab flange qauv:
- European System: Sawv cev los ntawm German DIN tus qauv, uas kuj suav nrog cov qauv qub Soviet Union.
- American System: Sawv cev los ntawm American ANSI / ASME tus qauv.
- International Standards: ASME B16.5 (American Standard), BS4504 (British Standard), DIN (German Standard), JIS (Japanese Standard).
Hom Flanges
1. Flat Welded Flanges: Siv rau cov ntawv thov uas tsis tshua muaj siab, yooj yim rau nruab thiab tshem tawm.
2. Neck Flanges: Muab kev txhawb zog thiab siv rau hauv cov tshuab ua haujlwm siab.
3. Butt Weld Flanges: Muab kev sib txuas tsis sib haum thiab muaj zog, tsim nyog rau kev siv siab.
4. Nplhaib Joint Flanges: Muab cov ntaub ntawv pov thawj kev sib txuas, feem ntau siv nyob rau hauv qhov chaw muaj kev kub ntxhov thiab kub kub.
5. Qhov (socket) Weld Flanges: Siv rau cov kav dej me me uas muaj qhov siab siab, muab cov bore du.
6. Qhov muag tsis pom Flanges: Siv los kaw qhov kawg ntawm cov kav dej, muab kev ruaj ntseg foob.
