Taw qhia rau Brass Ball Valve
Brass pob li qub yog cov khoom tseem ceeb hauv ntau qhov kev lag luam vim lawv cov qauv sealing zoo thiab ntau yam khoom xaiv. Tsab ntawv xov xwm no yog txhawm rau tshawb nrhiav cov qauv kev sib khi thiab cov khoom siv xaiv uas cuam tshuam nrog lub pob tooj dag, qhia txog lawv qhov tseem ceeb hauv kev siv sib txawv.
1. Sealing Structure ntawm Brass Ball Valve
Lub sealing qauv ntawm lub pob tooj dag pob valve plays lub luag haujlwm tseem ceeb hauv nws qhov kev ua tau zoo thiab kev ntseeg tau. Feem ntau, tooj dag pob li qub muaj lub pob nrog lub qhov, uas tig los tswj cov dej ntws. Lub tshuab sealing muaj kev sib txuas ntawm cov rooj zaum, cov ntsaws ruaj ruaj, thiab cov khoom ntim khoom. Cov rooj zaum, feem ntau yog ua los ntawm PTFE los yog lwm yam ntaub ntawv resilient, muab lub kaw ntom nti thaum lub pob nyob rau hauv qhov chaw kaw. Cov ntsaws ruaj ruaj, xws li O-rings lossis gaskets, tiv thaiv kom tsis txhob tawm ntawm lub cev thiab qia. Tsis tas li ntawd, cov ntaub ntawv ntim khoom, feem ntau yog PTFE lossis graphite, xyuas kom muaj kev ruaj ntseg nyob ib ncig ntawm lub qia kom tiv thaiv kom tsis txhob muaj kev kub ntxhov.
2. Kev xaiv cov khoom siv rau Brass Ball Valve
Kev xaiv ntawm cov ntaub ntawv rau tooj dag pob li qub yog qhov tseem ceeb rau lawv cov kev ua tau zoo, kev ua haujlwm ntev, thiab kev sib raug zoo nrog cov xov xwm sib txawv. Brass, tooj liab-zinc alloy, yog cov khoom siv tseem ceeb siv rau lub cev lub cev vim nws qhov zoo heev corrosion kuj thiab machinability. Cov muaj pes tsawg leeg ntawm tooj dag tuaj yeem sib txawv, nrog cov alloys xws li C36000 thiab C37700. Cov alloys muaj qhov sib npaug ntawm lub zog, ductility, thiab corrosion kuj haum rau ntau yam kev siv.
3. Kev txiav txim siab ntawm pob khoom
Kev xaiv cov khoom siv rau lub pob khoom ntawm lub pob tooj dag yog nyob ntawm cov yam ntxwv xws li hom kua dej tswj thiab kev ua haujlwm. Cov pob tooj dag feem ntau yog tsim los ntawm tib lub alloy raws li lub cev valve rau kev sib raug zoo thiab sib xws. Txawm li cas los xij, hauv cov ntawv thov uas muaj cov kua dej corrosive lossis abrasive, lub pob yuav raug coated lossis lined nrog cov ntaub ntawv xws li chrome plating lossis ceramic los txhim kho kev ua haujlwm ntev thiab kev ua haujlwm.
4. Cov khoom siv zaum thiab foob
Cov rooj zaum thiab cov ntsaws ruaj ruaj yog cov ntsiab lus tseem ceeb ntawm cov qauv sib khi hauv cov pob zeb tooj dag. PTFE (polytetrafluoroethylene), tseem hu ua Teflon, feem ntau yog siv rau cov rooj zaum vim nws cov tshuaj tiv thaiv zoo heev thiab tsis muaj kev sib txhuam. PTFE lub rooj zaum muab lub kaw ntom ntom thiab ua haujlwm du, txawm tias nyob rau hauv kev kub siab lossis kev siv kub. Cov ntsaws ruaj ruaj, suav nrog O-rings thiab gaskets, feem ntau yog tsim los ntawm cov khoom siv elastomeric xws li Nitrile (Buna-N) lossis Viton, xaiv raws li kev sib raug zoo nrog cov phiaj xwm kev tshaj tawm thiab kev ua haujlwm.
5. Kev txiav txim siab ib puag ncig thiab kev ruaj ntseg
Nyob rau hauv xyoo tas los no, tau muaj kev loj hlob ntawm kev xav txog ib puag ncig thiab kev ruaj ntseg hauv kev tsim thiab tsim cov pob zeb tooj dag. Cov neeg tsim khoom tau tsom mus rau kev txo qis ib puag ncig ntawm cov txheej txheem tsim khoom, txhim kho kev siv peev txheej, thiab koom nrog cov khoom siv rov ua dua tshiab. Tsis tas li ntawd, kev nce qib hauv kev sib khi thev naus laus zis thiab cov khoom siv tshawb fawb tau ua rau muaj kev txhim kho ntawm eco-phooj ywg cov ntsaws ruaj ruaj thiab cov ntaub ntawv ntim khoom, ntxiv dag zog rau kev ruaj khov ntawm tooj dag pob li qub.
Hauv kev xaus, cov qauv kev sib khi thiab kev xaiv cov khoom siv yog qhov tseem ceeb ntawm cov pob zeb tooj dag, cuam tshuam rau lawv cov kev ua tau zoo, kav ntev, thiab kev cuam tshuam ib puag ncig. Los ntawm kev nkag siab txog cov xwm txheej no thiab txiav txim siab xaiv, cov neeg siv tuaj yeem ua kom ntseeg tau tias kev ua haujlwm ruaj khov thiab kev ruaj khov mus ntev ntawm lub tshuab tooj dag pob valve hauv ntau daim ntawv thov.
