Valve Gasket Muaj nuj nqi & Daim Ntawv Thov Kev Qhia

Valve gaskets yog tsim los tiv thaiv cov xau los ntawm lub siab, corrosion, thiab thermal expansion / contraction ntawm cov khoom. Thaum yuav luag txhua flangedkev sib txuas's valves xav tau gaskets, lawv cov ntawv thov tshwj xeeb thiab qhov tseem ceeb sib txawv raws li hom valve thiab tsim. Hauv seem no,TWSyuav piav qhia txog valve installation txoj haujlwm thiab xaiv cov khoom siv gasket.

I. Thawj daim ntawv thov ntawm gaskets yog nyob rau ntawm flange sib koom ntawm valve kev sib txuas.

Feem ntau siv valve

1. Rooj vag Valve
2. Globe Valve
3. Npauj npaim valve(tshwj xeeb tshaj yog cov concentric thiab ob chav eccentric flanged npauj npaim valve)
4. Kuaj valve

Nyob rau hauv cov li qub no, lub gasket tsis yog siv rau kev khiav dej num los yog sealing nyob rau hauv lub valve nws tus kheej, tab sis yog ntsia nruab nrab ntawm ob flanges (nruab nrab ntawm lub flange ntawm lub valve nws tus kheej thiab cov yeeb nkab flange). Los ntawm kev zawm cov bolts, txaus clamping quab yuam yog tsim los tsim ib lub foob zoo li qub, tiv thaiv kom tsis txhob muaj qhov nruab nrab ntawm qhov sib txuas. Nws txoj haujlwm yog txhawm rau sau qhov tsis sib xws me me ntawm ob qhov chaw hlau flange, kom ntseeg tau 100% kev sib khi ntawm qhov sib txuas.

II.Daim ntawv thov ntawm Gasket hauv Valve "Valve Cover"

Ntau lub valve yog tsim los nrog lub cev sib cais thiab npog kom yooj yim rau kev saib xyuas sab hauv (piv txwv li, hloov lub rooj zaum, disc li qub, lossis tshem cov khib nyiab), uas yog tom qab ntawd bolted ua ke. Lub gasket tseem yuav tsum tau ntawm qhov kev sib txuas no kom ntseeg tau tias lub foob kaw ntom ntom.

1. Kev sib txuas ntawm lub npog valve thiab lub cev lub cev ntawm lub rooj vag valve thiab lub ntiaj teb valve feem ntau yuav tsum tau siv lub gasket los yog O-ring.
2. Lub gasket ntawm txoj haujlwm no kuj tseem ua haujlwm zoo li qub los tiv thaiv qhov nruab nrab los ntawm kev tawm ntawm lub cev valve mus rau hauv qhov chaw.

III. Tshwj xeeb gasket rau hom valve tshwj xeeb

Qee lub valve suav nrog lub gasket ua ib feem ntawm lawv cov core sealing los ua ke, tsim los ua ke hauv cov qauv valve.

1. Npauj npaim valve- valve rooj gasket

• Lub rooj zaum ntawm npauj npaim valve yog tiag tiag lub nplhaib gasket, uas yog nias rau hauv lub puab phab ntsa ntawm lub valve lub cev los yog ntsia ib ncig ntawm npauj npaim disc.
• Thaum npauj npaimdisckaw, nws nias lub valve lub rooj gasket los tsim ib tug dynamic foob (raws li tus npauj npaimdisctig).
• Cov khoom siv feem ntau yog roj hmab (piv txwv li, EPDM, NBR, Viton) lossis PTFE, tsim kom haum rau ntau yam xov xwm thiab kub kub.

2. Pob Valve-Valve Seat Gasket

• Lub rooj zaum ntawm lub pob valve kuj yog ib hom gasket, feem ntau yog ua los ntawm cov ntaub ntawv xws li PTFE (polytetrafluoroethylene), PEEK (polyetheretherketone), los yog cov yas muaj zog.
• Nws muab lub foob ntawm lub pob thiab lub cev lub cev, ua haujlwm ob qho tib si raws li lub foob zoo li qub (kwv yees rau lub cev lub cev) thiab lub foob dynamic (kwv yees rau lub pob rotating).

IV. Dab tsi li qub feem ntau tsis siv nrog gaskets?

1. Welded li qub: Lub cev valve yog ncaj qha welded mus rau lub raj xa dej, tshem tawm qhov xav tau ntawm flanges thiab gaskets.
2. Valves nrog threaded kev twb kev txuas: Lawv feem ntau siv threaded sealing (xws li raw cov ntaub ntawv los yog sealant), feem ntau tshem tawm qhov xav tau gaskets.
3. Monolithic li qub: Qee lub pob uas tsis tshua muaj nqi lossis cov khoom tshwj xeeb muaj lub cev lub cev uas tsis tuaj yeem muab tshem tawm, yog li tsis muaj lub valve npog gasket.
4. Valves nrog O-rings los yog hlau-pob gaskets: Nyob rau hauv high-pressure, high-temperature, los yog tshwj xeeb-nruab nrab daim ntaub ntawv, advanced sealing kev daws teeb meem yuav hloov cov pa tsis-metallic gaskets.

V. Summary:

Valve gasket yog ib hom kev txiav qhov tseem ceeb sealing, nws yog dav siv nyob rau hauv cov kav dej sib txuas ntawm ntau yam flange li qub, thiab tseem siv rau hauv lub valve npog sealing ntawm ntau lub li qub. Hauv kev xaiv, nws yog qhov yuav tsum tau xaiv cov khoom siv gasket uas tsim nyog thiab daim ntawv raws li hom valve, hom kev sib txuas, nruab nrab, kub thiab siab.
