Hauv kev lag luam ntawm cov li qub kev lag luam, cov li qub npauj npaim tau siv dav hauv ntau yam lag luam xws li roj thiab roj av, kev kho dej, kev ua tshuaj lom neeg, thiab lwm yam. Ntawm ntau hom li qub npauj npaim, ob hom yog cov ua ntej: ob lub li qub npauj npaim eccentric thiab peb lub li qub npauj npaim eccentric. Hauv qhov kev sib piv no, peb yuav saib tob txog kev tsim qauv, qhov zoo, qhov tsis zoo thiab kev siv ntawm ob lub li qub no.
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 qhov eccentricity ntawm tus ncej, uas yog, qhov offset ntawm tus ncej axis los ntawm kab nruab nrab ntawm cov kav dej, thiab qhov offset thib ob yog qhov foob eccentricity, uas yog, geometry ntawm lub valve disc seal. Qhov kev tsim no muaj qhov zoo thiab qhov tsis zoo.
Qhov zoo ntawm ob chav eccentric npauj npaim valve
1. Txo kev hnav
Lub hom phiaj ntawm qhov tsim ntawm tus ncej eccentricity yog kom txo qhov kev sib txhuam ntawm lub phaj valve thiab lub rooj zaum valve thaum lub sijhawm qhib thiab kaw, yog li ntawd txo qhov hnav thiab txo qhov kev pheej hmoo ntawm kev xau. Nws kuj tseem tuaj yeem ua kom lub neej ntawm lub npauj npaim valve ntev dua thiab txo cov nqi txij nkawm.
2. Kev sib khi zoo dua
Qhov thib ob eccentricity ua rau qhov chaw sealing kov lub rooj zaum valve tsuas yog nyob rau theem kawg ntawm kev kaw, uas tsis yog tsuas yog ua kom muaj kev sib khi zoo, tab sis kuj tswj tau qhov nruab nrab.
3. Txo lub zog torque
Qhov kev tsim ob npaug ntawm qhov sib txawv txo qhov coefficient ntawm kev sib txhuam, uas txo cov zog uas yuav tsum tau qhib thiab kaw lub valve npauj npaim.
4. Kev sib khi ob sab
Ob chav eccentric npauj npaim li qub tuaj yeem muab kev sib khi ob txoj kev, tso cai rau kev ntws ob txoj kev, thiab yooj yim dua rau kev teeb tsa thiab siv.
Qhov tsis zoo ntawm ob chav eccentric npauj npaim valves:
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 siab dua piv rau cov kab nruab nrab npauj npaim li qub.
2. Ntau lub zog dej poob
Vim yog lub phaj valve ob chav eccentric tuab dua, lub rooj zaum valve tawm los, thiab cov kev hla nqaim dua, qhov dej poob siab los ntawm lub valve npauj npaim yuav nce ntxiv.
3. Qhov kub tsawg
Ob chav eccentric npauj npaim li qub yuav raug txwv thaum tuav cov khoom siv kub qis heev lossis kub siab vim tias cov ntaub ntawv siv yuav tsis tiv taus qhov kub thiab txias heev.
Triple Offset npauj npaim valve
Lub qhov valve peb npaug offset yog ib qho kev txhim kho ntxiv ntawm lub qhov valve uas muaj peb qhov offsets. Vim yog ob chav eccentric, qhov thib peb eccentricity yog qhov offset ntawm lub axis piv rau qhov chaw nruab nrab ntawm lub cev valve. Qhov kev tsim tshiab no yog qhov zoo dua li lub qhov valve nruab nrab.
Qhov zoo ntawm triple eccentric npauj npaim li qub
1. Tsis muaj qhov xau
Lub duab tshwj xeeb ntawm lub sealing element ntawm lub triple eccentric butterfly valve tshem tawm kev sib txhuam thiab kev hnav, ua rau lub sealing nruj thoob plaws lub neej ntawm lub valve.
2. Kub thiab siab ua haujlwm siab
Ob lub valve triple eccentric butterfly uas yog hlau tag nrho thiab lub valve triple eccentric butterfly uas muaj ntau txheej tuaj yeem tswj tau cov kua dej kub thiab cov kua dej siab.
3. Tsim kom tsis kub hnyiab
Txhua yam khoom siv ntawm lub triple eccentric npauj npaim valve tuaj yeem ua tau raws li cov qauv hluav taws kub nruj, ua rau nws zoo tshaj plaws hauv cov ntawv thov hluav taws kub.
4. Tsawg torque thiab kev sib txhuam
Lub triple eccentric npauj npaim valve tuaj yeem txo qhov kev ua haujlwm torque thiab kev sib txhuam, yog li ua tiav kev ua haujlwm du, txo qhov torque thiab ntev lub neej kev pabcuam.
5. Ntau yam kev siv
Lub triple eccentric npauj npaim valve yog tsim rau ntau yam kev siv, suav nrog roj thiab roj av, petrochemical, hluav taws xob tsim thiab kev lag luam refining.
Qhov tsis zoo ntawm triple eccentric npauj npaim valves
1. Tus nqi siab dua
Lub triple eccentric npauj npaim valve feem ntau muaj tus nqi tsim khoom siab dua vim nws tsim qauv thiab cov qauv siab heev.
2. Kev poob taub hau siab dua me ntsis
Qhov offset ntxiv hauv qhov tsim triple eccentric yuav ua rau lub taub hau poob siab dua me ntsis dua li lub valve ob chav eccentric.
Ob chav eccentric npauj npaim valve VS peb eccentric npauj npaim valve
1. Lub rooj zaum valve
Lub rooj zaum ntawm lub valve ob chav eccentric feem ntau yog muab tso rau hauv ib lub qhov ntawm lub phaj valve thiab yog ua los ntawm roj hmab xws li EPDM, yog li nws tuaj yeem ua tiav lub foob airtight, tab sis nws tsis haum rau kev siv kub heev. Lub rooj zaum ntawm lub valve peb chav eccentric yog hlau tag nrho lossis ntau txheej, yog li nws haum rau cov kua kub lossis cov kua dej corrosive.
2. Tus nqi
Txawm hais tias nws yog tus nqi tsim qauv lossis qhov nyuaj ntawm cov txheej txheem tsim khoom, cov li qub peb npaug eccentric npauj npaim siab dua li cov li qub ob npaug eccentric npauj npaim. Txawm li cas los xij, qhov zaus ntawm kev saib xyuas tom qab cov li qub peb npaug eccentric qis dua li cov li qub ob npaug eccentric.
3. Lub zog tig
Lub hom phiaj thawj zaug ntawm kev tsim lub valve triple eccentric yog kom txo qhov hnav thiab kev sib txhuam ntxiv. Yog li ntawd, lub zog ntawm lub valve triple eccentric butterfly yog me dua li ntawm lub valve double eccentric butterfly.
