Dab tsi yog ob hom qauv ntawm npauj npaim li qub?
Npauj npaim valve yog ib hom ntawm lub quarter-tig valve uas yog siv los tswj lossis cais cov dej ntws los ntawm cov yeeb nkab. Nws muaj lub disc zoo li lub valve uas tig hauv cov yeeb nkab kom tswj tau qhov ntws. Muaj ob hom kev sib txawv ntawm npauj npaim li qub uas feem ntau siv: lub concentric butterfly valve thiab eccentric npauj npaim valve.
Concentric Npauj Npaim Valve:
Lub concentric npauj npaim valve yog qhov siv dav tshaj plaws thiab yooj yim tshaj plaws ntawm hom npauj npaim valve. Nws muaj ib lub disc uas muab tso rau hauv nruab nrab ntawm cov yeeb nkab thiab tig ib ncig ntawm lub axis uas tseem nyob rau hauv nruab nrab ntawm cov yeeb nkab. Lub disc txuas nrog lub qia uas dhau los ntawm lub cev valve thiab ua haujlwm los ntawm tus kov, gearbox, lossis actuator. Thaum lub valve qhib tag nrho, lub disc yog sib npaug rau cov yeeb nkab axis, tso cai rau tsis muaj kev txwv. Thaum lub valve raug kaw, lub disc yog perpendicular mus rau cov yeeb nkab axis, kaw qhov ntws tag.
Concentric npauj npaim li qub muaj ntau yam zoo. Ua ntej, lawv muaj qhov yuav tsum tau muaj lub zog qis, uas txhais tau hais tias lawv tuaj yeem ua haujlwm manually lossis nrog lub actuator me me. Lawv kuj muaj cov qauv tsim compact, ua rau lawv haum rau qhov chaw nruj. Tsis tas li ntawd, lawv muab bidirectional sealing, uas txhais tau hais tias lawv tuaj yeem foob tiv thaiv kev kub ntxhov los ntawm ob qho tib si. Qhov no ua rau lawv haum rau cov ntawv thov uas qhov kev hloov pauv hloov pauv.
Cov li qub no feem ntau siv rau hauv cov ntawv thov uas kaw nruj tsis yog qhov yuav tsum tau ua, xws li hauv HVAC systems, cov chaw kho dej, thiab kev tiv thaiv hluav taws. Lawv kuj tsim nyog rau kev tuav ntau cov kua dej, suav nrog cov kua dej, cov pa roj, thiab cov slurries. Txawm li cas los xij, lawv yuav tsis tsim nyog rau cov ntawv thov uas xav tau kev kub siab lossis kub ua haujlwm, vim tias cov elastomer hauv ob sab phlu tuaj yeem ua rau tsis zoo nyob rau hauv cov xwm txheej zoo li no.
Eccentric Npauj Npaim Valve:
Lub eccentric npauj npaim valve yog variation ntawm concentric npauj npaim valve. Nws muaj qhov sib txawv ntawm qhov sib txawv, uas txhais tau hais tias lub axis ntawm kev sib hloov tsis nyob hauv nruab nrab ntawm lub valve. Hloov chaw, nws yog offset rau ib sab ntawm lub cev valve. Qhov kev tsim no tso cai rau lub disc kom tshem tawm txoj kev ntws tawm thaum lub valve qhib, txo cov kev txwv ntws thiab txo qis qis.
Eccentric npauj npaim li qub feem ntau muab faib ua ob hom: ob chav eccentric thiab triple eccentric li qub. Ob chav eccentric li qub muaj ib qho offset, thaum triple eccentric li qub muaj ob qho tib si offset thiab lub kaum sab xis. Lub eccentricity thiab inclination ntawm lub valve muab kev txhim kho sealing kev ua tau zoo thiab durability piv rau concentric npauj npaim li qub.
Cov li qub no feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum tau kaw nruj nreem, xws li hauv cov roj thiab cov kav dej, cov chaw tsim hluav taws xob, thiab cov chaw ua tshuaj. Lawv muaj peev xwm tswj tau siab dua thiab kub dua li qhov sib txawv ntawm npauj npaim li qub, ua rau lawv haum rau qhov xav tau ib puag ncig. Txawm li cas los xij, lawv xav tau lub zog siab dua los ua haujlwm thiab tej zaum yuav kim dua li qhov sib txawv ntawm npauj npaim li qub.
Xaus:
Hauv kev xaus, npauj npaim li qub tau siv dav hauv ntau qhov kev lag luam rau kev khiav dej num thiab kev sib cais. Ob qhov yooj yim qauv ntawm npauj npaim li qub, concentric npauj npaim valve thiab eccentric npauj npaim valve, txhua tus muaj lawv qhov zoo thiab kev siv. Lub concentric npauj npaim valve yog qhov yooj yim, compact, thiab haum rau cov ntawv thov uas tsis tshua muaj siab. Ntawm qhov tod tes, eccentric npauj npaim valve muab kev sib khi zoo dua thiab tsim nyog rau kev siv siab thiab kub siab. Kev nkag siab qhov sib txawv ntawm ob hom ntawm npauj npaim li qub tuaj yeem pab xaiv lub valve tsim nyog rau ib daim ntawv thov tshwj xeeb.
