Dab tsi yog Dual Phaj Check Valve Gaskets
Dual Phaj Check Valve Gaskets nyob nruab nrab ntawm lub valve disc thiab lub cev valve kom ntseeg tau tias kev sib khi ntawm lub valve. Nws feem ntau yog ua los ntawm cov khoom siv elastic xws li roj hmab lossis polymer. Lub gasket muaj qee qhov kev elasticity thiab tuaj yeem hloov mus rau lub cev lub cev thiab qhov chaw disc los tsim kev sib txuas. Thaum lub valve kaw, lub gasket yog compressed, tiv thaiv cov kua los ntawm lub valve. Thaum lub valve qhib, lub gasket yuav elastically deform me ntsis kom ntseeg tau tias cov dej ntws zoo.
Cov qauv thiab cov khoom siv
Dual Phaj Check Valve Gaskets yog cov khoom sib khi tsim tshwj xeeb rau ob lub phaj kos li qub, thiab lawv cov kev tsim kho thiab cov khoom xaiv yog qhov tseem ceeb rau lub valve kev ua haujlwm.
Qauv
- Sealing interface: Lub gasket feem ntau yog nyob rau ntawm qhov chaw sib cuag ntawm ob sab ntawm lub valve, uas yog, ob lub phaj. Thaum lub valve raug kaw, lub gasket nyob rau hauv siab thiab deforms, sau qhov sib txawv ntawm ob daim hlau los tsim ib tug sealing interface.
- Puab: Cov duab ntawm lub gasket feem ntau yog sib npaug ntawm qhov sib khi ntawm lub valve kom ntseeg tau tias txawm tias lub siab faib thiab kev sib khi zoo thaum lub valve raug kaw.
Khoom siv
- Roj Hmab: Haum rau kev kho dej dav dav thiab kev siv tsis tshua muaj siab. Cov khoom siv roj hmab muaj qhov zoo elasticity thiab yoog raws thiab tuaj yeem tiv taus cov tshuaj corrosion mus rau qee yam.
- Polytetrafluoroethylene (PTFE): Vim nws cov tshuaj zoo heev ruaj khov thiab kub tsis kam, PTFE gaskets yog tsim rau tuav ntau yam tshuaj, tshwj xeeb tshaj yog nyob rau hauv high kub thiab corrosive ib puag ncig.
- Hlau filling cov ntaub ntawv: xws li asbestos, iav fiber, los yog carbon fiber-filled gaskets. Cov ntaub ntawv no txhim kho cov neeg kho tshuab lub zog thiab hnav tsis kam ntawm gasket thiab tsim nyog rau kev kub siab thiab kub ib puag ncig.
- Cov ntaub ntawv tshwj xeeb: Rau cov ntawv thov tshwj xeeb, xws li corrosive lossis kub kub ib puag ncig, yuav tsum muaj cov ntaub ntawv tshwj xeeb, xws li fluorine roj hmab (Viton), silicone roj hmab (Silicone), lossis lwm yam khoom siv hluavtaws.
Muaj nuj nqi thiab cov teebmeem
■ Sealing muaj nuj nqi: Dual phaj check valve gaskets nyob nruab nrab ntawm lub valve disc thiab lub valve lub cev, ua si lub luag hauj lwm sealing. Thaum lub valve kaw, lub gasket yog compressed los xyuas kom meej sealing kev sib cuag ntawm lub valve thiab lub valve lub cev kom tiv thaiv tau cov kua rov qab los yog to. Cov khoom siv elastic ntawm lub gasket hloov mus rau qhov sib txawv ntawm cov duab sib txawv los tsim cov foob zoo.
■ Tiv thaiv kev thim rov qab: Lub luag haujlwm tseem ceeb ntawm ob lub phaj kos valve yog los tiv thaiv cov dej rov qab hauv cov kav dej. Thaum cov dej ntws mus rau qhov sib txawv, lub valve disc yuav kaw thiab cia siab rau lub gasket sealing kev ua tau zoo los tiv thaiv cov dej ntws. Qhov no tiv thaiv cov kua dej ntws rov qab thiab tiv thaiv kev ua haujlwm ntawm cov kav dej.
■ Txo qhov poob siab: Piv nrog rau lwm hom kev kos li qub, Dual phaj kos valve muaj qhov poob siab. Kev tsim thiab xaiv cov khoom siv ntawm lub gasket tuaj yeem txo qhov kev tiv thaiv ntawm cov kua dej los ntawm sab hauv ntawm lub valve, txo qhov poob siab, thiab txhim kho kev ua haujlwm ntawm lub cev.
■ Muab kev ntseeg tau: Dual phaj check valve gaskets yog tsim thiab tsim nyob rau hauv nruj zoo tswj kom ntseeg tau lawv kev ntseeg tau thiab kav ntev. Lawv tuaj yeem ua haujlwm ib txwm nyob rau hauv kev ua haujlwm hnyav xws li kev kub siab, kub siab, thiab corrosive media, thiab muaj lub neej ua haujlwm ntev.

Installation & Kho
Txhim kho thiab tswj xyuas ob lub phaj kos valve gaskets yog cov kauj ruam tseem ceeb hauv kev ua kom lub valve ua haujlwm zoo thiab kev ntseeg tau ntev. Nov yog cov lus qhia ntxaws ntxaws ntawm kev teeb tsa thiab kev saib xyuas ntawm cov gaskets:
Cov txheej txheem installation
Kev Npaj: Ua ntej kev teeb tsa, lub valve thiab nws cov kav dej uas nyob ib sab yuav tsum tau ntxuav kom huv si kom tshem tawm cov khoom txawv teb chaws xws li vuam slag, ntoo chips, lossis cov khib nyiab yas.
Kos lub gasket: xyuas kom lub gasket tsis puas los yog deformed, thiab xyuas seb nws cov khoom haum rau cov xov xwm nws yuav tsum tau tuav.
Tso lub gasket: Muab lub gasket kom raug nruab nrab ntawm ob sab ntawm lub valve, ua kom lub gasket sib npaug ntawm tag nrho cov sealing nto.
Txhim kho lub valve: Txhim kho lub valve raws li cov chaw tsim khoom siv phau ntawv qhia, kom ntseeg tau tias cov kev taw qhia ntawm lub valve yog raws li cov kev taw qhia ntawm kev tshaj tawm. Yog tias muaj ib qho cim kos rau ntawm lub valve, ua raws li nws.
Tighten bolts: Siv qhov tseeb torque kom nruj bolts sib npaug thiab tsis txhob nruj dhau, uas yuav ua rau gasket deformation lossis puas.
Kuaj lub valve: Tom qab kev teeb tsa tiav lawm, sim lub valve los kuaj xyuas cov dej xau thiab xyuas kom lub valve qhib thiab kaw zoo.
Cov lus pom zoo txog kev tu
Kev tshuaj xyuas tsis tu ncua: Tshawb xyuas qhov xwm txheej ntawm lub gasket tsis tu ncua, tshwj xeeb tshaj yog thaum lub valve kaw, kom paub tseeb tias lub gasket tsis hnav lossis puas.
Kev ntxuav thiab hloov pauv: Yog tias lub gasket pom tias puas los yog pom cov tsos mob ntawm cov xov xwm tawm, lub gasket yuav tsum tau ntxuav los yog hloov nrog ib tug tshiab.
Tsis txhob xeb: Rau ib puag ncig uas yuav tshwm sim corrosion, gaskets ntawm corrosion-resistant cov ntaub ntawv yuav tsum tau siv thiab cov gaskets yuav tsum tau soj ntsuam tsis tu ncua rau cov cim ntawm corrosion.
Kev Cia Kom Zoo: Yog tias yuav tsum tau hloov lub gasket, lub gasket tshiab yuav tsum muab khaws cia rau hauv qhov chaw qhuav, huv si kom deb ntawm kev sib cuag nrog roj lossis lwm yam khoom uas yuav ua rau muaj kab mob.
Ua raws li cov txheej txheem kev nyab xeeb: Thaum ua haujlwm tu, yuav tsum ua raws li cov txheej txheem kev nyab xeeb, suav nrog kev hnav cov khoom tiv thaiv tus kheej tsim nyog thiab ua kom cov valve raug kaw thiab ua rau muaj kev ntxhov siab.
