Cov yam ntxwv tseem ceeb ntawm Gas Welded Ball Valves
1. Cov khoom siv thiab corrosion kuj
Valve Lub Cev Khoom: Feem ntau yog ua los ntawm carbon steel (piv txwv li, WCB), stainless hlau (xws li, 304, 316L), lossis qis-kub steel (xws li, LCB) kom hloov mus rau cov yam ntxwv thiab kev ua haujlwm ntawm cov pa roj sib txawv.
Sealing Materials: Siv cov pa roj carbon monoxide-cov ntaub ntawv sealing resistant, xws li polytetrafluoroethylene (PTFE), para-polystyrene (PPL), los yog hlau sealing qauv los xyuas kom meej ntev - lub sij hawm sealing kev ua tau zoo.
Anti-Kev kho corrosion: Lub valve lub cev nto tuaj yeem coated los yog plated nrog anti- xeb coatings kom ntev kev pab cuam lub neej.
2. Welded kev twb kev txuas
Txoj kev sib txuas: Butt welding lossis socket welding yog siv los xyuas kom muaj kev sib txuas ntawm lub valve thiab cov raj xa dej, txo qhov kev pheej hmoo ntawm kev xau.
Qhov zoo: Cov kev sib txuas welded muaj zog dua li kev sib txuas flange, haum rau siab - siab, siab - kub, lossis faus cov kav dej, thiab tshem tawm cov teeb meem ntawm cov ntsia liaj qhov rooj loosening lossis gasket aging.
3. Kev tsim qauv tsim
Floating Ball lossis Fixed Ball Structure:
Floating Ball: Lub pob nias nruj nreem tiv thaiv lub rooj zaum hauv qab lub siab ntawm qhov nruab nrab, ua tiav ob txoj kev sib khi, haum rau nruab nrab thiab qis - siab. Fixed Pob: Lub pob tau txais kev txhawb nqa los ntawm cov kabmob sab saud thiab sab qis, thiab lub rooj zaum valve tau txais kev them nyiaj los ntawm cov springs lossis nruab nrab siab, haum rau siab -siab, loj- txoj kab uas hla.
Fireproof Design: Qee cov li qub tau nruab nrog cov qauv hluav taws xob sib khi, tswj xyuas qee theem ntawm kev sib khi txawm tias muaj hluav taws kub los tiv thaiv cov xwm txheej thib ob los ntawm cov pa xau.
Anti-Static Design: Cov khoom siv hluav taws xob tau teeb tsa nruab nrab ntawm lub pob thiab lub valve qia, thiab nruab nrab ntawm lub qia valve thiab lub cev lub cev, txhawm rau tiv thaiv cov hluav taws xob zoo li qub uas tuaj yeem ua rau lub txim.
4. Kev ua haujlwm thiab kev tswj xyuas
Kev Tswj Xyuas Kev Ua Haujlwm: Nruab nrog lub kov lossis lub thawv iav, haum rau me me - txoj kab uas hla li qub.
Hluav taws xob / Pneumatic Actuator: Ua kom muaj kev tswj xyuas chaw taws teeb thiab kev ua haujlwm tsis siv neeg, haum rau cov ntawv loj - txoj kab uas hla lossis daim ntawv thov uas yuav tsum tau hloov ntau zaus.
Limit Device: Xyuas kom lub valve qhib tag nrho thiab kaw, tiv thaiv kev puas tsuaj los ntawm lub zog ntau dhau.
5. Kev ua tau zoo zoo
High Sealing Performance: Zero-kev tsim tawm, ua tau raws li cov kev cai nruj nruj ntawm kev lag luam roj.
High Pressure Resistance: tuaj yeem tiv taus qhov ntsuas siab txog PN100 (10MPa) lossis Chav Kawm 600.
Tsawg-kub tsis kam: Qee cov li qub yog tsim rau cov kab mob cryogenic xws li -46℃rau -196 degree, thiab muaj feem xyuam rau cov roj liquefied natural gas (LNG).
Lub neej ua haujlwm ntev: Siab- cov ntaub ntawv zoo thiab kev ua haujlwm zoo ua kom ntev - lub sijhawm ua haujlwm ruaj khov ntawm cov li qub nyob rau hauv cov xwm txheej hnyav.
