Kev Ntsuam Xyuas Tus Qauv: Floating Ball

"Floating Ball" yog hais txog cov txheej txheem tshwj xeeb uas lub pob tau ruaj ntseg thiab txhawb nqa hauv lub cev valve.

Txoj Cai Ua Haujlwm: Hauv qhov tsim no, lub pob tsis kho los ntawm kev txhawb nqa ncej (trunnion). Hloov chaw, nws yog "floated" thiab tuav hauv qhov chaw los ntawm ob lub rooj zaum elastic valve.

Sealing Mechanism: Thaum lub valve nyob rau hauv txoj hauj lwm kaw thiab raug xov xwm siab, lub upstream siab thawb lub pob me ntsis mus rau sab downstream. Qhov no ua rau lub pob nias nruj nreem rau lub rooj zaum hauv qab, tsim kom muaj kev ruaj ntseg foob (feem ntau hu ua "downstream sealing" effect).

Nta: Cov qauv yooj yim thiab muab kev sib khi zoo heev. Txawm li cas los xij, txij li thaum lub siab load ntawm lub pob yog xa ncaj qha mus rau lub rooj zaum valve, floating pob li qub feem ntau haum raume me mus rau nruab nrab(eg, DN15–DN200) thiabqis rau nruab nrab siabcov xwm txheej los tiv thaiv kev hnav ntau dhau ntawm lub rooj zaum.

FAQ

ASTM A351 CF8 khoom yog dab tsi?

ASTM A351 CF8 yog cov khoom siv austenitic stainless hlau siv rau kev tsim siab -muaj cov castings. Nws yog siv dav hauv cov khoom siv hauv kev lag luam- xws li li qub, flanges, thiab cov yeeb nkab fittings - thiab tshwj xeeb tshaj yog zoo - haum rau cov ntawv thov hauv corrosive lossis siab - qhov kub thiab txias.

Cov khoom siv no yog tsim los ntawm American Society for Testing and Materials (ASTM) thiab raug xaiv raws li ASTM A351/A351M-Txheej txheem Specification rau Castings, Austenitic, rau siab-Cov khoom. Nws cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab ua tau raws li cov kev xav tau ntawm kev lag luam. CF8 sib haum mus rau qib cam khwb cia ntawm 304 stainless hlau, muab zoo heev corrosion kuj, toughness, thiab weldability.

Lub pob valve ua haujlwm li cas?

Lub pob valve ua tiav unidirectional sealing los ntawm kev siv lub siab ntawm qhov nruab nrab los thawb lub pob khov kho tiv thaiv lub rooj zaum hauv qab; Nws cov ntsiab lus tseem ceeb ntawm kev ua haujlwm yog nyob ntawm lub xeev "floating" ntawm lub pob hauv lub valve kab noj hniav. Qhib thiab kaw yuav tsum tsuas yog 90℃kev sib hloov ntawm lub valve qia, muab kev ua haujlwm yooj yim thiab tsis tshua muaj dej tsis kam.
