Ob chav offset npauj npaim valve yog ib hom npauj npaim valve uas muaj ntau txoj kev tsim thiab ntau yam piv rau cov npauj npaim valve yooj yim. Nws yog tus cwj pwm los ntawm ob qhov sib txawv ntawm qhov sib txawv ntawm qhov geometry ntawm lub valve Cheebtsam, tshwj xeeb tshaj yog cov disc los yog "npauj npaim", uas muab nws sib nrug ntawm tus qauv npauj npaim valve. Cov offsets no muab kev txhim kho kev sib khi thiab kev tswj xyuas ntau dua ntawm kev khiav hauv ntau daim ntawv thov.
Ob chav offset tsim nta ob qhov tseem ceeb hauv qab no:
Eccentric Shaft Offset: Thawj qhov offset yog nyob rau hauv daim ntawv ntawm ib tug eccentric (off-center) ncej. Hauv lwm lo lus, cov ncej uas npauj npaim lossis disc tau nruab rau yog nyob deb ntawm qhov nruab nrab ntawm lub cev valve. Qhov offset no pab txo kev sib txhuam thiab hnav ntawm lub disc thiab lub rooj zaum, tso cai rau kev kaw kom nruj dua thiab txhim kho kev sib khi.
Eccentric Disc Offset: Qhov thib ob offset suav nrog cov duab ntawm lub disc nws tus kheej. Lub disc tsis nyob hauv nruab nrab ntawm lub valve lub voj voog lub cev; Hloov chaw, nws yog offset los ntawm qhov nruab nrab ntawm cov yeeb nkab. Qhov eccentricity no ua rau lub disc tig tsis tau rub tawm ntawm lub rooj zaum valve, uas txo qis hnav thiab tso cai rau lub foob nruj dua.
Cov txiaj ntsig ntawm ob qhov offset npauj npaim valve muaj xws li:
Enhanced Sealing: Lub eccentric disc thiab ncej offsets txo kev sib txhuam thiab hnav, txhim kho lub peev xwm sealing ntawm lub valve. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas qhov kev ruaj ntseg kaw yog qhov tseem ceeb.
Tsawg Torque thiab Hnav: Qhov txo qis hauv kev tsim qauv txhais tau hais tias nws yuav tsum muaj lub zog tsawg dua los khiav lub valve. Nws kuj ua rau muaj kev hnav tsawg dua ntawm cov khoom siv valve, ua rau lub neej ntev ntawm lub valve.
Kev Ua Haujlwm Siab: Ob chav offset npauj npaim li qub muaj peev xwm tuav cov kev siv hluav taws xob siab thiab kub kub, ua rau lawv tsim nyog rau ntau yam kev lag luam, suav nrog roj thiab roj, petrochemical, hluav taws xob, thiab lwm yam.
Bubble-Tight Shut-Off: Ob chav offset npauj npaim li qub tuaj yeem ua tiav npuas-nruj kaw-tawm, uas yog qhov tseem ceeb hauv kev lag luam uas txawm tias me me xau tsis tuaj yeem lees txais.
Versatility: Lawv tuaj yeem siv rau hauv ob qho tib si rau / tawm thiab throttling (tswj) daim ntawv thov, muab ntau yam kev daws teeb meem rau kev tswj ntws.
Ob chav offset npauj npaim li qub feem ntau yog siv rau hauv cov ntawv thov uas muaj kev tswj xyuas meej, kev tuav lub siab, thiab kev ruaj ntseg kaw yog tsim nyog. Lawv feem ntau ua haujlwm hauv kev lag luam uas cov txheej txheem tswj cov kua dej yog qhov tseem ceeb, xws li hauv kev lag luam roj thiab roj, kev tsim hluav taws xob, kev ua tshuaj, thiab kev kho dej.
