Lub v-pob valve yuav tsum muaj lub luag haujlwm ntawm kev khiav dej num thiab kev ua haujlwm ntawm qhov nruab nrab rau cov impurity hais ntawm cov kua.
1. Lub pob valve muaj tib yam 90 degree rotary nkaus, qhov sib txawv yog tias lub cev ntsaws yog ib tug kheej kheej, nrog ib puag ncig lub qhov lossis los ntawm los yog channel los ntawm nws cov axis ntawm cov channel. Pob valve feem ntau yog siv rau cov kav dej txiav tawm, faib thiab hloov cov kev taw qhia ntawm qhov nruab nrab, nws tsuas yog yuav tsum tig 90 degrees ua haujlwm, lub zog me me tuaj yeem kaw nruj nreem. Pob li qub yog tsim rau kev hloov thiab txiav li qub, tab sis nyob rau xyoo tas los no txoj kev loj hlob ntawm pob li qub nrog throttling thiab tswj ntws, xws li v-pob li qub.
2. Haum rau kev ua haujlwm qhib thiab kaw tsis tu ncua, yooj yim qhib thiab kaw, tsis muaj dej tsis kam, cov qauv yooj yim, me me, lub teeb yuag, yooj yim los tswj, zoo sealing kev ua tau zoo, kev cuam tshuam ntawm cov kev taw qhia ntawm cov xov xwm ntws, tsis muaj kev vibration, tsis muaj suab nrov.
Eccentric ib nrab pob li qub tsis muaj kev tswj xyuas, tuaj yeem siv rau cov kua dej uas muaj cov khoom tsis huv.
1. Cov kua dej me me, nws cov coefficient kuj sib npaug ntawm qhov ntev.
2. Cov qauv yooj yim, ntim me me, lub teeb yuag
3. Pob valve sealing khoom yog nruj thiab txhim khu kev qha, dav siv hauv cov yas, kev sib khi zoo, dav siv hauv tshuab nqus tsev.
4. Kev ua haujlwm yooj yim, qhib thiab kaw nrawm, los ntawm kev qhib tag nrho mus rau tag nrho kaw tsuas yog tig 90, yooj yim los tswj cov kev ncua ntev.
5. Cov qauv siv hluav taws xob muaj qhov zoo ntawm kev saib xyuas yooj yim, cov qauv yooj yim ntawm lub pob valve, cov qauv yooj yim ntawm lub nplhaib sib khi, yooj yim disassembly thiab hloov.
6. Thaum qhib tag nrho los yog kaw tag nrho, lub sealing nto ntawm lub pob thiab lub rooj zaum yog cais tawm ntawm qhov nruab nrab. Thaum qhov nruab nrab hla dhau, nws yuav tsis ua rau corrosion ntawm sealing nto ntawm lub valve.
7. Kev siv ntau yam, nrog rau txoj kab uas hla ntawm me me mus rau ob peb millimeters, thiab qhov ntau thiab tsawg ntawm lub tshuab nqus tsev mus rau qhov siab siab tuaj yeem siv tau.
Thaum lub pob rotates 90 degrees, nws yuav tsum tag nrho cov duab kheej kheej ntawm lub qhov hluav taws xob thiab qhov hluav taws xob, yog li txiav tawm qhov ntws. Eccentric ib nrab pob valve yog ib yam tshiab ntawm lub pob valve, nws muaj nws tus kheej cov qauv tshwj xeeb zoo, xws li kev sib txhuam tsis sib hloov, sealing tsis yooj yim rau hnav, me me hloov torque. Qhov no txo cov adapter specifications. Txais siv ntau qhov kev sib hloov hluav taws xob actuator, nws tuaj yeem tswj thiab txiav tawm qhov nruab nrab. Nws yog dav siv hauv roj av, tshuaj lom neeg, dej hauv nroog thiab kev lag luam ntws.
