Double Offset Npauj Npaim Valve vs Triple Offset Npauj Npaim Valve?

Dab tsi yog qhov txawv ntawm ob chav eccentric thiab triple eccentric npauj npaim valve?

Rau kev lag luam li qub, ob qho tib si eccentric npauj npaim li qub thiab triple eccentric npauj npaim li qub tuaj yeem siv roj thiab roj, tshuaj thiab dej kho, tab sis tuaj yeem muaj qhov sib txawv loj ntawm ob hom npauj npaim li qub, yog li nws tseem ceeb kom paub qhov txawv. nruab nrab ntawm ob hom li qub no txhawm rau ua qhov kev xaiv zoo.

Hauv tsab xov xwm no, peb yuav saib qhov sib txawv tseem ceeb ntawmob chav offset npauj npaim li qubthiabtriple offset npauj npaim li qubnrog rau lawv qhov zoo thiab kev siv.

Ua ntej, kev tsim thiab kev tsim kho yog txawv.

Lub disc ntawmob chav eccentric npauj npaim valveyog offset los ntawm centerline ntawm lub valve lub cev thiab ncej. Qhov kev tsim offset no pab kev sib txhuam thiab hnav ntawm lub rooj zaum ntawm lub qhov muag muag thaum qhib thiab kaw, yog li ncua kev pab cuam lub neej thiab txhim kho kev sib khi. Thaum lub npe hu ua triple eccentric npauj npaim valve muaj qhov thib peb eccentric nyob rau sab saum toj ntawm ob lub eccentric, piv txwv li, nws tsim cov duab conical nyob rau hauv lub sealing nto, thiab cov khoom ntawm sealing nto feem ntau yog hlau sealing, uas ua rau kom nruj sealing thiab kev sib txhuam tsawg dua, ua rau nws zoo tagnrho rau kev siv high-pressure thiab high-temperature.

Qhov thib ob, qhov kev ua tau zoo sib txawv.

Triple eccentric npauj npaim li qubmuab ntau yam zoo dua ob chav eccentric designs. Lub triple eccentric tsim muab cov huab cua nruj, uas txhais tau hais tias cov dej xau tuaj yeem tiv thaiv tau zoo txawm tias nyob rau hauv qhov kub thiab txias. Yog li nws yog qhov tsim nyog rau cov ntawv thov tseem ceeb uas yuav tsum tau kaw nruj. Tsis tas li ntawd, triple eccentric npauj npaim valve lub khob hliav qab npog tsim txhim kho kev hnav tsis kam kom lub sijhawm txij nkawm tuaj yeem txuas ntxiv thiab kho cov nqi txo. Cov txiaj ntsig kev ua tau zoo no ua rau triple eccentric npauj npaim valve yog thawj qhov kev xaiv rau kev thov hauv cov roj thiab roj, petrochemical thiab hluav taws xob tsim kev lag luam.

Thaum kawg, the tus nqi ntawm kev tsim kho tsis siv.

Qhov zoo tshaj plaws ntawmob chav eccentric npauj npaim valvepiv nrog triple eccentric npauj npaim valve yog tias tus nqi ntawm kev tsim kho yog me ntsis qis. Yog tias qhov kev ua haujlwm tsis xav tau qhov kub thiab txias siab triple eccentric npauj npaim valve, ob chav eccentric npauj npaim valve yog qhov kev xaiv pheej yig dua. Qhov no yog vim hais tias ob chav eccentric npauj npaim li qub yog tsim rau cov ntawv thov uas muaj qhov nruab nrab siab thiab kub. Lawv txhim khu kev qha kev ua tau zoo thiab cov nqi-zoo ua rau lawv muaj kev xaiv nrov rau ntau yam kev lag luam.

Hauv kev xaus, kev xaiv ntawm ob thiabtriple eccentric npauj npaim li qubnyob ntawm cov kev cai tshwj xeeb ntawm qhov nruab nrab thiab ib puag ncig. Triple eccentric npauj npaim li qub yog tsim rau cov xwm txheej uas xav tau kev sib khi siab nrog rau kev ua haujlwm siab thiab kub, thaum ob chav eccentric li qub muab cov txiaj ntsig zoo rau cov ntawv thov tsawg dua.
