Nyob rau hauv kev lag luam li qub, npauj npaim li qub tau siv dav hauv ntau yam kev lag luam xws li roj thiab roj, kev kho dej, kev ua tshuaj, thiab lwm yam. Ntawm ntau hom npauj npaim li qub, ob hom kev coj ua: ob chav eccentric npauj npaim valve thiab triple eccentric. npauj npaim valve.Hauv qhov kev sib piv zoo no, peb yuav ua tib zoo saib qhov tsim, qhov zoo, qhov tsis zoo thiab kev siv ntawm ob lub valve.
Ob chav Offset npauj npaim valve
Raws li lub npe qhia, ob chav offset npauj npaim li qub muaj ob qhov offsets: thawj qhov offset yog cov ncej eccentricity, uas yog, qhov offset ntawm ncej axis los ntawm qhov nruab nrab ntawm cov kav dej, thiab qhov thib ob offset yog lub foob eccentricity, uas yog, geometry ntawm lub valve disc foob.Qhov kev tsim no muaj qhov zoo thiab qhov tsis zoo.
Qhov zoo ntawm ob chav eccentric npauj npaim valve
1. Txo hnav
Lub hom phiaj ntawm tus ncej eccentricity tsim yog los txo qhov kev sib txhuam ntawm lub phaj valve thiab lub rooj zaum valve thaum lub sijhawm qhib thiab kaw, yog li txo qis hnav thiab txo qhov kev pheej hmoo ntawm kev xau.Nws tseem tuaj yeem txuas lub neej ntawm npauj npaim valve thiab txo cov nqi kho.
2. Txhim kho sealing
Qhov thib ob eccentricity ua rau lub sealing nto hu rau lub rooj zaum valve tsuas yog nyob rau theem kawg ntawm kev kaw, uas tsis tsuas yog ua kom lub sealing nruj, tab sis kuj zoo tswj qhov nruab nrab.
3. Txo torque
Qhov kev tsim qauv ob npaug txo qhov kev sib txhuam coefficient, uas txo cov quab yuam kom qhib thiab kaw npauj npaim valve.
4. Bidirectional sealing
Ob chav eccentric npauj npaim li qub tuaj yeem muab ob txoj kev sib khi, tso cai rau bidirectional ntws, thiab yooj yim dua rau nruab thiab siv.
Disadvantages ntawm ob eccentric npauj npaim li qub:
1. Tus nqi siab dua
Cov qauv tsim thiab cov ntaub ntawv ntawm ob chav eccentric npauj npaim li qub feem ntau ua rau cov nqi tsim khoom ntau dua piv rau cov npauj npaim centerline li qub.
2. Kev poob dej ntau dua
Vim lub thickness ob chav eccentric valve phaj, protruding valve lub rooj, thiab nqaim txoj kab, cov dej siab poob los ntawm npauj npaim valve yuav nce.
3. Txwv kub ntau yam
Ob chav eccentric npauj npaim li qub yuav raug txwv thaum tuav ultra-tsawg kub los yog kub xov xwm vim hais tias cov ntaub ntawv siv yuav tsis tiv taus huab cua kub.
Triple Offset npauj npaim valve
Triple offset npauj npaim valve sawv cev rau kev txhim kho ntxiv ntawm npauj npaim valve tsim nrog peb offsets.Nyob rau hauv lub hauv paus ntawm ob eccentric, qhov thib peb eccentricity yog qhov offset ntawm lub axis piv rau qhov chaw ntawm lub valve lub cev.Qhov kev tsim tshiab no yog qhov tshwj xeeb zoo dua li cov tsoos centerline npauj npaim valve.
Qhov zoo ntawm triple eccentric npauj npaim li qub
1. Zero to
Cov duab tshwj xeeb ntawm cov khoom sib khi ntawm triple eccentric npauj npaim valve tshem tawm kev sib txhuam thiab hnav, ua rau lub foob nruj thoob plaws lub neej ntawm lub valve.
2. Kev kub siab thiab kev kub siab ua haujlwm
Ob qho tag nrho-hlau triple eccentric npauj npaim valve thiab ntau txheej triple eccentric npauj npaim valve tuaj yeem tswj tau qhov kub thiab txias siab.
3. Fireproof tsim
Tag nrho cov ntaub ntawv ntawm triple eccentric npauj npaim valve tuaj yeem ua tau raws li cov qauv hluav taws xob nruj, ua rau nws zoo heev hauv kev siv hluav taws xob.
4. Tsawg torque thiab kev sib txhuam
Triple eccentric npauj npaim valve tuaj yeem txo qis kev khiav hauj lwm torque thiab kev sib txhuam, yog li ua tiav kev ua haujlwm du, txo lub zog thiab ncua kev pab cuam lub neej.
5. Kev siv ntau yam
Triple eccentric npauj npaim valve yog tsim rau ntau yam kev siv, suav nrog roj thiab roj, petrochemical, tsim hluav taws xob thiab kev lag luam refining.
Disadvantages ntawm triple eccentric npauj npaim li qub
1. Tus nqi siab dua
Lub triple eccentric npauj npaim valve nyiam kom muaj tus nqi pib tsim ntau dua vim nws cov qauv tsim thiab cov qauv siab heev.
2. Lub taub hau poob qis dua me ntsis
Qhov ntxiv offset nyob rau hauv lub triple eccentric tsim yuav ua rau me ntsis siab dua lub taub hau poob dua li ob lub eccentric valve.
Ob chav eccentric npauj npaim valve VS triple eccentric npauj npaim valve
1. Lub rooj zaum valve
Lub rooj zaum ntawm ob lub eccentric npauj npaim valve feem ntau yog embedded nyob rau hauv ib tug zawj ntawm lub valve phaj thiab yog ua los ntawm roj hmab xws li EPDM, yog li nws muaj peev xwm ua tau ib tug airtight foob, tab sis nws tsis haum rau ultra-siab kub daim ntaub ntawv.Lub rooj zaum ntawm lub rooj zaum triple eccentric npauj npaim valve yog tag nrho-hlau lossis ntau txheej, yog li nws yog qhov tsim nyog rau cov dej kub lossis dej corrosive.
2. Tus nqi
Txawm hais tias nws yog tus tsim qauv lossis kev tsim cov txheej txheem nyuaj, triple eccentric npauj npaim li qub yog siab dua ob npaug eccentric npauj npaim li qub.Txawm li cas los xij, qhov zaus ntawm kev kho tom qab ntawm triple eccentric li qub yog qis dua li ntawm ob lub eccentric li qub.
3. Lub zog
Thawj lub hom phiaj ntawm triple eccentric npauj npaim valve tsim yog kom txo qis hnav thiab kev sib txhuam.Yog li ntawd, lub torque ntawm triple eccentric npauj npaim valve yog me dua li ntawm ob lub eccentric npauj npaim valve.
