Cov khoom tseem ceeb ntawm lub pob valve muaj xws li lub pob, lub cev lub cev, thiab lwm yam khoom siv sab hauv. Cov khoom siv dav dav rau kev tsim cov pob valve muaj xws li:
Lub cev Valve:
Carbon Steel: Cov pa roj carbon steel yog cov khoom siv rau lub cev valve, tshwj xeeb tshaj yog nyob rau hauv kev lag luam kev siv uas lub zog thiab durability yog qhov tseem ceeb.
Stainless hlau: Stainless hlau, xws li 316 stainless hlau, yog corrosion-resistant thiab haum rau daim ntaub ntawv uas tsis kam mus rau hnyav tshuaj los yog corrosive ib puag ncig yog tsim nyog.
Alloy Steels: Ntau yam hlau alloys, xws li duplex stainless hlau, tuaj yeem siv los txhim kho corrosion thiab txhim kho cov khoom siv kho tshuab.
Pob:
Stainless Hlau: Lub pob nws tus kheej feem ntau yog ua los ntawm stainless hlau, muab kev tiv thaiv corrosion thiab kav ntev.
Chrome Plated Brass lossis Bronze: Hauv qee qhov kev siv, tshwj xeeb tshaj yog nyob rau hauv qhov me me lossis qis qis, lub pob yuav ua los ntawm chrome-plated tooj dag lossis tooj liab.
Khoom siv zaum:
Polymer Seats: Cov khoom siv lub rooj zaum mos ua los ntawm cov khoom siv polymers xws li PTFE (polytetrafluoroethylene) los yog lwm yam fluoropolymers feem ntau yog siv los muab lub foob kaw ntom nti thiab txo qhov kev pheej hmoo ntawm kev xau.
Hlau Rooj: Hlau rooj, feem ntau ua los ntawm stainless hlau los yog lwm yam alloys, tej zaum yuav siv tau rau daim ntaub ntawv uas yuav tsum tau kub siab los yog siab kuj.
qia:
Stainless hlau: Lub qia, uas txuas tus kov los yog actuator rau lub pob, feem ntau yog ua los ntawm stainless hlau rau lub zog thiab corrosion kuj.
Seals thiab Gaskets:
PTFE (Teflon): PTFE feem ntau yog siv rau cov ntsaws ruaj ruaj thiab gaskets vim nws cov tshuaj tiv thaiv zoo heev thiab tsis muaj kev sib txhuam.
Kev xaiv cov khoom siv rau lub pob valve yog nyob ntawm cov yam ntxwv xws li hom kua dej, qhov kub thiab txias, siab, thiab ib puag ncig.
