Dab tsi yog tus npauj npaim eccentric valve?
Eccentricity nyob rau hauv ib tug npauj npaim valve yog hais txog qhov kev txhob txwm ua haujlwm ntawm lub valve disc cov rotoring axis (qia) thiab lub valve lub cev nruab nrab lossis salting nto. Thaum lub qia ntawm tus tsoos Centerline Npauj npaim Valve, tus npauj npaim offset rau kev sib txhuam ntawm lub nplhaib valve Raws li cov kev taw qhia thiab tus nqi ntawm offset, npauj npaim li qub tuaj yeem faib ua peb pawg hauv qab no:
1. Ib leeg-eccentric Npauj Npaim Valve: Center Center tau offset los ntawm lub cev nruab nrab ntawm nruab nrab tab sis koom rau ntawm cov chaw sib khi. Qhov kev tawm no feem ntau yog 5% ntawm lub valve disc tuab thiab haum rau cov khoom siv qes-siab, ib txwm-kev siv hluav taws xob, xws li cov tshuab dej.
2. Ob-eccentric Npauj Npaim Valve: off yog offset los ntawm ob lub valve lub cev nruab nrab ntawm nruab nrab thiab cov chaw sib khi ntawm qhov chaw, ua rau muaj ob zaug offset. Cov qauv tsim no tso cai rau lub disc kom sai sai ntawm kev sib khi saum npoo thaum qhib, txo kev hnav. Nws yog feem ntau siv nyob rau hauv cov roj av thiab kev lag luam siv tshuaj lom neeg.
3. Triple Eccentric Npauj Npaim Valve: Raws li ob chav eccentric valve, lub valve lub rooj sib npaug ntawm qhov chaw tsis muaj qhov chaw sib txhuam (feem ntau 8℃-12 cov qib kev sib txhuam. Nws tiv thaiv kom kub thiab siab nias (txog 600℃/ pn100, raws li API 609 txuj ci) thiab feem ntau yog siv hauv cov nroj tsuag muaj zog lossis cov haujlwm ua haujlwm hnyav.
Dab tsi yog nruab nrab npauj npaim valve
Npauj Npaim Npauj Npaim Valve yog ib lub valve muaj rau ntawm / tawm hloov chaw nyob rau hauv cov roj av, tshuaj tswj, tshuaj tua kab, thiab kev lag luam hydroLower. Nws cov qauv txheej txheem tseem ceeb yog cov kev sib txawv ntawm cov qia Axis, Disc Center, thiab lub cev tsim khoom thiab ntsuas kom yooj yim thiab kaw lub zog.
Lub valve no pratemes ntws tswj los ntawm kev sib hloov lub disc ntawm 0℃thiab 90 degree. Kev tsim qauv tsim txom los ntawm cov khoom sib khi tsis zoo ntawm cov khoom kub kub hnyiab thiab hnav ntawm disc thiab lub rooj zaum. Kev ua haujlwm siab, txhim kho cov qauv t-puab cov txheej txheem ntawm cov khoom siv hluav taws xob sib xyaw ua ke nrog cov khoom siv kub ntawm ob qho tib si ntawm ob qho nyuaj thiab cov ntaub mos muag muag. Lub caij nplooj ntoo hlav hluav taws xob tau them nyiaj thiab ua kom haum rau qhov kub-, kev kub siab ib puag ncig thiab cov nyiaj Bidirectional thauj. Lub valve muaj nyob rau hauv ntau hom qauv txheej txheem, suav nrog lub cim kaw thiab Eccentric. Sealing cov ntaub ntawv suav nrog cov ntsaws ruaj ruaj (xws li EPDM roj hmab thiab PTFE) thiab tawv hlau ntsaws ruaj ruaj. Cov kev xaiv ua muaj xws li phau ntawv, hluav taws xob, thiab pneumatic. Xyuas kom meej flange ua dlej zog thaum lub teeb nruab. Lub sijhawm qhib thiab kaw ntawm lub valve rau ncua sij hawm kaw yuav tsum tiv thaiv los ntawm muab tso. Nws cov qauv tsim muaj maj mam nthuav dav rau cov ntawv thov hluav taws xob loj, thiab tau mob siab rau cov khoom siv ua kom zoo thiab cov kev daws teeb meem zoo.
Dab tsi yog qhov sib txawv ntawm eccentric Npauj Npaim Valve thiab secectorf Npauj Npaim Valve
I. Cov Qauv Tsim Qauv
Center Npab Npauj Npaim Valve (Cegrine Npauj Npaim Valve)
Lub Valve Cov Qwj Axis, Disc Center, thiab valve lub chaw nruab nrab lub chaw ua ke.
Cov kev tiv tauj disc thiab rubs tiv thaiv lub rooj valve thoob plaws ntawm kev qhib thiab kaw txheej txheem, ua rau hnav kom ceev.
Eccentric Npauj Npaim Valve
Ib qho eccentric xwb: lub valve lub qia yog offset los ntawm disc Center, txo kev rho tawm tab sis tseem ua rau sib txhuam.
Ob chav ECCENTRIC: lub valve lub qia yog offset los ntawm ob lub disc Center thiab lub chaw ua haujlwm, tso cai rau lub rooj zaum sai sai los ntawm kev qhib thiab kaw, txo qis kev sib txhuam ntawm 90%.
Triple ECCENTRIC: Raws li ob chav tsim qauv ECCENTRIC, cov khoom sib khi sib khi ua kom ua tiav cov xoom-sib ceg.
Ii. Sealing Kev Ua Tau Zoo thiab Cov Khoom Siv
Center Npauj Npaim Valve
Kev ntseeg cov ntaub ntawv mos muag xws li Roj Hmab / PTFE, uas ua tiav lub foob los ntawm kev deformation Elastic.
Qhov kub tsis kam kub tsis kam (feem ntau tsawg dua lossis sib npaug rau 80 degree) thiab tsis zoo ua rau muaj kev kub siab.
Eccentric Npauj Npaim Valve
Ob chav Eccentric: lub rooj hlau tuaj yeem siv, txhim kho cov kub ua kom tsis kam, tab sis lub foob no yog nyob rau hauv kab kev sib cuag thiab nquag mus rau hauv kev kub siab. Triple-eccentric: kev foob hlau: hlau foob, hu rau cov npoo av siab nce nrog nruab nrab siab, ua tiav xoom kev kub siab thiab kub siab.
III. Cov Ntawv Thov
Chaw Npauj Npaim Valve:
Qhov kub thiab txias thiab ib puag ncig lub zog (xws li hluav taws roj kav thiab dav dav Industrial dej khoom).
Cov txiaj ntsig zoo: Cov qauv yooj yim thiab tus nqi qis.
ECCENTRIC Npauj Npaim Valve:
Ob-ECCENTRIC: Nruab Nrab Nruab Nrab thiab Nruab Nrab Nruab Nruab Nruab (xws li Chav Pipelines thiab Circulating Dej).
Triple-eccentric: kub thiab kub hnyav hnyav (xws li hluav taws xob cog cov roj thiab cov nkev muaj roj).
Cov txiaj ntsig: Lub neej ntev, hnav tsis kam, thiab kev siv dav dav ntau.
