Txoj kev sib txuas ntawm Valve
Apr 15, 2024| Flange kev twb kev txuas
Qhov no yog daim ntawv txuas feem ntau siv hauv cov li qub. Raws li cov duab ntawm qhov sib koom ua ke, nws tuaj yeem muab faib ua cov hauv qab no:
1. Hom du: siv rau cov li qub uas tsis tshua muaj siab. Kev ua haujlwm yooj yim dua
2. Concave-convex hom: Kev ua haujlwm siab yog siab thiab nruab nrab-nyuaj washers tuaj yeem siv tau.
3. Hom nplaig-thiab-groove: Gaskets nrog cov yas deformation loj tuaj yeem siv tau, uas yog siv dav hauv kev tawm corrosive thiab muaj kev sib khi zoo dua.
4. Trapezoidal groove hom: Siv lub nplhaib hlau oval li gasket, siv rau li qub nrog kev ua haujlwm siab Ntau dua lossis sib npaug li 64 kg / cm2, los yog kub kub li qub.
5. Hom Lens: Lub gasket yog nyob rau hauv cov duab ntawm lub lens thiab yog ua los ntawm hlau. Siv rau lub siab-siab li qub nrog kev ua haujlwm siab Ntau dua los yog sib npaug li 100 kg / cm2, los yog qhov kub-kub li qub.
6. O-ring hom: Qhov no yog daim ntawv flange txuas tshiab. Nws tau tsim nrog qhov tshwm sim ntawm ntau yam roj hmab O-rings. Nws muaj cov nyhuv sealing hauv daim ntawv txuas.
clamp kev twb kev txuas
Siv cov bolts los ncaj nraim rau lub valve thiab cov kav dej ntawm ob qho kawg ua ke.
Butt weld kev twb kev txuas
Ib txoj kev sib txuas uas ncaj qha welded rau cov yeeb nkab.
Threaded kev twb kev txuas
Qhov no yog ib txoj kev sib txuas yooj yim feem ntau siv rau ntawm cov li qub me me. Muaj ob qhov xwm txheej:
1. Direct sealing: Cov xov sab hauv thiab sab nraud ncaj qha ua cov ntsaws ruaj ruaj. Txhawm rau kom ntseeg tau tias cov pob qij txha tsis xau, lawv feem ntau ntim nrog cov roj txhuas, cov ntaub pua chaw thiab polytetrafluoroethylene raw khoom tapes. Ntawm lawv, polytetrafluoroethylene raw khoom tapes yog nce siv; Cov khoom siv no muaj kev ua haujlwm zoo corrosion thiab zoo heev sealing nyhuv. Nws yog qhov zoo heev thiab yooj yim rau siv thiab khaws cia. Thaum disassembling, nws tuaj yeem raug tshem tawm tag nrho vim nws yog cov yeeb yaj kiab uas tsis yog nplaum, uas yog qhov zoo tshaj rau cov roj thiab cov ntaub pua plag.
2. Indirect sealing: Lub zog ntawm cov xov nruj yog xa mus rau lub gasket ntawm ob lub dav hlau, cia lub gasket ua lub foob.
