Npauj npaim valveyog hais txog ib hom valve uas nws kaw qhov (disc los yog npauj npaim phaj) yog ib tug disc, uas tig ib ncig ntawm lub valve ncej kom ua tiav qhib thiab kaw.Nws yog tsuas yog siv rau kev txiav tawm thiab throttling ntawm lub raj xa dej.
Tus npauj npaim valve qhib thiab kaw ib feem yog lub phaj zoo li npauj npaim disc, uas tig ib ncig ntawm nws tus kheej axis hauv lub valve lub cev kom ua tiav lub hom phiaj ntawm kev qhib thiab kaw lossis hloov kho.Npauj npaim valve feem ntau tsawg dua 90 "los ntawm kev qhib siab mus rau tag nrho kaw,
Npauj npaim valve thiab npauj npaim qia tsis muaj peev xwm ntsuas tus kheej.Rau qhov chaw ntawm lub phaj npauj npaim, lub iav iav reducer yuav tsum tau muab ntsia rau ntawm lub qia valve.Kev siv cov cab iav reducer tuaj yeem tsis tsuas yog ua rau tus npauj npaim phaj nws tus kheej xauv thiab nres lub phaj npauj npaim ntawm txhua txoj haujlwm, tab sis kuj txhim kho kev ua haujlwm ntawm lub valve.
Kev lag luam npauj npaim valve yog tus cwj pwm los ntawm kev kub siab ua haujlwm, siab siv tau ntau yam, qhov loj nominal txoj kab uas hla, thiab lub valve lub cev yog ua los ntawm cov hlau.
Lub nplhaib sealing ntawm lub valve phaj siv lub nplhaib hlau tsis siv lub nplhaib roj hmab.Qhov loj kub npauj npaim valve yog ua los ntawm steel phaj vuam, thiab yog tsuas yog siv rau flue ducts thiab gas pipes ntawm kub xov xwm.
Kev teeb tsa thiab kev saib xyuas ntawm npauj npaim valve yuav tsum tau them sai sai rau cov khoom hauv qab no: Thaum lub sijhawm teeb tsa, lub valve disc yuav tsum tau nres hauv qhov chaw kaw.Txoj haujlwm qhib yuav tsum tau txiav txim siab raws li lub kaum sab xis ntawm lub phaj npauj npaim.
Rau npauj npaim li qub nrog lub bypass valve, lub bypass valve yuav tsum tau qhib ua ntej qhib
Kev teeb tsa yuav tsum tau ua raws li cov lus qhia ntawm lub chaw tsim khoom, thiab qhov hnyav npauj npaim valve yuav tsum tau nruab nrog lub hauv paus ruaj khov.
Qhov zoo ntawm npauj npaim li qub yog raws li hauv qab no: yooj yim thiab ceev qhib thiab kaw, txuag zog, tsis muaj dej tsis kam, thiab tuaj yeem ua haujlwm ntau zaus.
Cov qauv yooj yim, me me thiab lub teeb yuag.
Cov av nkos tuaj yeem thauj tau, nrog qhov tsawg kawg nkaus ntawm cov kua dej ntawm cov yeeb nkab qhov ncauj.
Nyob rau hauv qis qis, zoo sealing tuaj yeem ua tiav.
Kev kho kom haum zoo.
Qhov tsis zoo ntawm npauj npaim li qub yog raws li nram no: qhov ntau ntawm kev khiav hauj lwm siab thiab kev khiav hauj lwm kub yog me me.
Qhov nruj yog qhov tsis zoo.
Npauj npaim li qubtuaj yeem muab faib ua offset phaj hom, ntsug phaj hom, inclined phaj hom thiab qib qib raws li qauv.Raws li daim ntawv sealing, nws tuaj yeem muab faib ua ob hom: hom kaw ntom ntom thiab nyuaj kaw hom.Hom foob mos feem ntau siv lub nplhaib roj hmab foob, thiab cov foob tawv tawv feem ntau yog siv lub nplhaib hlau foob.
Raws li hom kev sib txuas, nws tuaj yeem muab faib ua flange kev twb kev txuas thiab wafer txuas;Raws li hom kev sib kis, nws tuaj yeem muab faib ua phau ntawv, iav kis tau tus mob, pneumatic, hydraulic thiab hluav taws xob.
