Fisher DA Tswj Valve
Fisher DA Control Valve Txheej txheem cej luam
Nyob rau hauv siab -cov ntawv thov kev poob siab, cov khoom siv sib cais-laden media, los yog cov txheej txheem uas yuav tsum tau siv tus kheej zoo- tso dej tawm, lub valve lub cev tsim feem ntau tseem ceeb tshaj li kev tswj hwm lawv tus kheej. CovFisher DA tswj valventa lub kaum ntse ntse lub cev tsim, leveraging ib tug pov thawj structural layout thiab ruaj khov kev ua tau zoo los muab ib tug txhim khu kev qha thiab kwv yees kev daws teeb meem rau xws li kev thov.
Fisher DA Valve yog dab tsi
Lub Fisher DA tswj valve yog ib qho -lub kaum sab xis lub cev valve, tsim los daws cov kev xav tau ntawm kev tswj hwm hauv kev pabcuam hnyav, suav nrog - siab poob siab thiab kev tshaj tawm uas muaj kev tuav pov hwm. Nws yog qhov tshwj xeeb tshaj yog tsim nyog rau kev teeb tsa uas xav tau kev hloov pauv cov kav dej, muaj zog rau tus kheej - tso dej tawm, lossis txo qis tshaj tawm hauv lub cev valve.
Nws tus qauv tsim tsom mus rau txoj hauv kev muaj zog txaus thiab cov txheej txheem layout es tsis yog cov yam ntxwv nyuaj, ua kom muaj kev tswj xyuas ruaj khov thiab ua haujlwm ntev - lub sijhawm ua haujlwm kev ntseeg siab hauv cov xwm txheej hnyav.
- Cov qauv tsim tseem ceeb muaj xws li:
Threaded valve lub kaus mom
Unbalanced coj plug
Threaded -insert seat
Hlau -rau- hlau sealing
"Downward kaw" kev ua
Cov yam ntxwv no muab cov qauv kev ruaj ntseg nrog kev ruaj ntseg sealing, tso cai rau lub valve hloov mus rau ntau yam kev sib tw kev lag luam.
Qhov zoo ntawm Lub Cev Lub Cev
Piv rau ncaj-los ntawm cov li qub, DA lub kaum sab xis lub cev teeb tsa muaj cov txiaj ntsig tseem ceeb hauv engineering:
- Strong self-draining peev xwm:Lub ntiajteb txawj nqus- pab khiav pab tshem tawm cov kua, condensate, los yog particulates, txo txoj kev pheej hmoo ntawm plug sticking los yog foob puas.
- Txo piping luj tshib:Lub cev 90℃tuaj yeem hloov tau ib lub luj tshib, txo qis tag nrho lub cev poob siab, txo cov ntsiab lus vuam, thiab txo qis txoj hauv kev xau.
- Kev tswj kom zoo ntawm cov xov xwm complex:Tsawg dua cov xov xwm khaws cia hauv kab noj hniav txhim kho kev hloov pauv rau cov khoom sib xyaw ua ke -laden lossis scaling- cov kua dej tsis zoo, ua kom lub neej ntev ntawm lub valve thiab txo cov zaus txij nkawm.
- Flexible installation:Txhawb ntau qhov kev taw qhia thiab ob qho tib si nce / nqis ntws cov lus qhia, zoo tagnrho rau qhov chaw - txwv kev teeb tsa lossis kev xa mus rau cov kav dej.
