ASTM A 105 Nfloating pob valveyog ib hom floating pob valve qhov twg lub pob tuaj yeemviav vias verticallynyob rau hauv nruab nrab siab, tseem hu ua lub pob valve. Nws yog tsim raulow-kub siv, muabzoo sealing thiab stabilityhauv kev tswj dej. Nrog nta xws liLub zog ua haujlwm qis, lub neej ua haujlwm ntev, thiab kev saib xyuas yooj yim, nws yog dav siv hauv kev lag luam xws lipetrochemical, metallurgy, thiab papermaking.
Txoj Cai Ua Haujlwm
Lub valve tswj ntws los ntawm kev tig lub pob90 degree:
Qhib: Thaum lub pob lub channel sib haum nrog lub valve lub cev, cov kua dej ntws.
Kaw: Thaum tig mus rau txoj hauj lwm ntsug, qhov ntws raug txiav tawm.
Cov yam ntxwv tseem ceeb
Tsawg-Qhov Kub Adaptability:
Ua los ntawmCov ntaub ntawv tshwj xeeb (xws li LCB, LC3, CF8)nrogkev kho mob cryogeniclos tiv thaiv brittle puas los yog deformation ntawm qhov kub thiab txias.
Sealing Performance:
Precision- pob hauv av thiab lub rooj zaumnrogcaij nplooj ntoos hlav- loaded redundant seals(piv txwv li, rooj zaum mos + hluav taws kub- lub rooj zaum nyab xeeb) raunpuas- kaw nruj.
Corrosion Resistance:
Stainless hlau (304/316)thiabPTFE / PCTFE foobxyuas kom muaj kev sib raug zoo nrog cov xov xwm corrosive.
Cov yam ntxwv tseem ceeb
Extended Neck Design:
Rau qhov kub thiab txiasqis dua -50 degree, a 250mm caj dabkhaws cov ntim saum toj no0 degree, tiv thaiv kev foob tsis ua haujlwm.
Tus kheej -Txoj haujlwm nyem:
Lub siab nyem qhovnyob rau hauv lub pob thiab lub rooj tso tawm kab noj hniav siab, zam kev puas tsuaj los ntawm thermal expansion.
Hluav taws kub & Static Protection:
Hluav taws kub-resistant graphite ntimthiabanti- khoom siv zoo li qubxyuas kom muaj kev ncaj ncees nyob rau hauv cov xwm txheej hnyav.
