Hauv kev siv hauv kev lag luam, kev xaiv lub valve ua lub luag haujlwm tseem ceeb hauv kev ua kom lub kaw lus ua haujlwm tau zoo thiab ntseeg tau. Lub valve nrov tshaj plaws hauv xyoo tas los no yog lub valve npauj npaim ob chav flange peb chav eccentric. Lub valve tsim tshiab no muaj ntau yam zoo, ua rau nws yog thawj qhov kev xaiv hauv ntau yam lag luam.

Ua ntej tshaj plaws, qhov kev tsim tshwj xeeb ntawm ob lub flange triple eccentric butterfly valve ua rau nws txawv ntawm cov npauj npaim ib txwm muaj. Qhov kev tsim "triple eccentricity" txhais tau tias peb qhov eccentricities uas muaj nyob hauv cov qauv valve, suav nrog qhov eccentricity ntawm lub qhov (shaft eccentricity), qhov cone centerline eccentricity thiab qhov sealing surface eccentricity. Qhov kev tsim no muab lub foob hermetic txawm tias nyob rau hauv kev siv siab thiab kub siab. Qhov kev tsim triple-eccentric kuj txo qhov hnav ntawm cov khoom foob, ua rau lub neej ua haujlwm ntev dua thiab txo qhov yuav tsum tau saib xyuas.

Ntxiv rau qhov tsim triple-eccentric, lub valve dual-flange configuration muaj ntau qhov zoo. Qhov tsim dual-flange yooj yim rau kev teeb tsa thiab tswj vim tias lub valve tuaj yeem yooj yim ntsia nruab nrab ntawm cov flanges yam tsis tas yuav muaj kev txhawb nqa ntxiv lossis kev sib dhos. Qhov no ua rau lub valve zoo tagnrho rau cov ntawv thov uas qhov chaw tsawg lossis qhov twg xav tau kev teeb tsa sai thiab ua haujlwm tau zoo.

Lwm qhov zoo ntawm ob chav flange peb npaug offset npauj npaim valve yog nws qhov ua tau ntau yam. Cov valve no haum rau ntau yam kev siv xws li roj thiab roj av, petrochemical, hluav taws xob thiab kev kho dej. Nws lub peev xwm los tswj cov siab thiab kub ua rau nws yog qhov kev xaiv zoo rau cov chaw ua haujlwm nyuaj. Tsis tas li ntawd, lub valve lub peev xwm kaw cua ua rau nws zoo tagnrho rau cov ntawv thov uas kev tiv thaiv kev xau yog qhov tseem ceeb, xws li thaum kov cov kua lom lossis cov kua txaus ntshai.

Tsis tas li ntawd xwb, lub valve ob chav flange peb chav eccentric muaj cov yam ntxwv tswj kev ntws zoo heev. Lub disc thiab lub rooj zaum tsim qauv txo qhov tsis kam ntws, txo qhov siab poob thiab txuag hluav taws xob. Qhov no ua rau lub valve no yog qhov kev xaiv zoo rau kev tswj kev ntws hauv cov kav dej thiab cov txheej txheem txheej txheem. Lub valve lub peev xwm ua kom nruj ua rau nws haum rau cov ntawv thov uas xav tau kev tswj kev ntws meej.

Hais txog kev xaiv cov khoom siv, ob chav flange peb chav eccentric npauj npaim li qub tuaj yeem ua los ntawm ntau yam khoom siv, suav nrog cov hlau carbon, hlau tsis xeb thiab cov hlau tsis tshua muaj. Qhov no tso cai rau kev sib raug zoo nrog ntau yam kua dej thiab kev ua haujlwm. Lub peev xwm los kho cov khoom siv valve ua kom lawv ua tau raws li cov kev xav tau tshwj xeeb ntawm ntau yam kev lag luam thiab kev siv.

Tsis tas li ntawd xwb, lub valve uas muaj ob lub flange thiab peb lub offset no yog tsim los kom ua haujlwm tau zoo thiab siv tau ntev. Lub cev ruaj khov thiab cov khoom siv zoo siv rau hauv cov txheej txheem tsim khoom ua kom lub valve tiv taus kev ua haujlwm hnyav thiab muab kev ua haujlwm zoo tas li thoob plaws nws lub neej ua haujlwm. Qhov kev ntseeg siab no yog qhov tseem ceeb rau kev tswj hwm kev ncaj ncees thiab kev ua haujlwm zoo ntawm cov txheej txheem kev lag luam.

Hauv kev xaus lus, lub Ob Chav Flange Triple Offset Butterfly Valve muaj ntau yam zoo uas ua rau nws yog ib qho khoom muaj nqis hauv kev siv hauv kev lag luam. Nws txoj kev tsim triple-eccentric, kev teeb tsa dual-flange, kev siv tau ntau yam, kev tswj kev ntws, kev xaiv cov khoom siv thiab kev ntseeg tau ua rau nws yog thawj qhov kev xaiv rau cov lag luam uas tab tom nrhiav kev daws teeb meem kev tswj kev ntws zoo thiab txhim khu kev qha. Nrog rau kev nce qib tas mus li ntawm thev naus laus zis, ob chav flange triple eccentric butterfly valve yuav ua lub luag haujlwm tseem ceeb hauv kev ua kom cov txheej txheem kev lag luam ua haujlwm zoo.
