Pneumatic pob valve yog ib hom pneumatic actuator dav siv hauv kev tswj tsis siv neeg niaj hnub no. Lub teeb liab tswj tau tsav lub pob valve hloov ua haujlwm los ntawm pneumatic actuator kom ua tiav qhov kev hloov pauv lossis hloov kev tswj ntawm qhov nruab nrab hauv cov kav dej.
Thawj qhov taw tes: kev xaiv ntawm pob valve
Connection hom: flange kev twb kev txuas, clamp kev twb kev txuas, internal xov kev twb kev txuas, sab nraud xov txuas, ceev sib dhos kev twb kev txuas, welded kev twb kev txuas (lub taub qab vuam kev twb kev txuas, qhov (socket) vuam kev twb kev txuas)
Valve lub rooj sealing: hlau nyuaj kaw lub pob valve, uas yog, lub sealing nto ntawm lub rooj zaum valve thiab lub sealing nto ntawm lub pob yog hlau rau hlau pob valve. Haum rau qhov kub thiab txias, muaj cov khoom siv, hnav tsis kam. Mos foob pob valve, lub rooj siv polytetrafluoroethylene PTFE, para-polystyrene PPL elastic sealing khoom, sealing nyhuv yog zoo, tuaj yeem ua tiav xoom xoom.
Valve khoom: WCB cam khwb cia hlau, tsis tshua muaj kub hlau, stainless hlau 304,304L, 316,316L, duplex hlau, titanium alloy, thiab lwm yam.
Kev khiav hauj lwm kub: kub li qub pob valve, -40 ℃ ~ 120 ℃. Nruab nrab kub pob valve, 120 ~ 450 ℃. Kub kub pob valve, ≥450 ℃. Tsawg kub pob valve -100 ~ -40 ℃. Ultra-low kub pob valve ≤100 ℃.
Ua haujlwm siab: tsis tshua muaj siab pob valve, nominal siab PN≤1.6MPa. Nruab nrab siab pob valve, nominal siab 2.0-6.4MPa. Siab siab pob valve ≥10MPa. Lub tshuab nqus tsev pob valve, qis dua ib qho chaw siab pob valve.
Cov qauv: floating pob valve, tsau pob valve, V pob valve, eccentric ib nrab pob valve, teb pob valve
Flow channel daim ntawv: los ntawm pob valve, peb-txoj kev pob valve (L-channel, T-channel), plaub-txoj kev pob valve
Qhov thib ob point: pneumatic actuator xaiv
Ob chav ua yeeb yam piston hom pneumatic actuator yog tsim los ntawm lub tog raj kheej, kawg npog thiab piston. Iav ncej. Txwv thaiv, kho cov ntsia hlau, qhov taw qhia thiab lwm yam. Siv cov cua compressed ua lub zog los thawb lub piston txav. Lub piston tau muab tso rau hauv lub khib kom tsav lub iav ncej kom tig 90 °, thiab tom qab ntawd tsav lub pob valve hloov ua haujlwm.
Ib leeg-ua yeeb yam piston hom pneumatic actuator feem ntau ntxiv lub caij nplooj ntoos hlav rov qab ntawm lub piston thiab lub hau kawg, uas tuaj yeem tso siab rau lub zog tsav ntawm lub caij nplooj ntoos hlav kom rov pib lub pob valve thiab ua kom txoj hauj lwm qhib lossis kaw thaum huab cua qhov chaw tsis raug. , thiaj li ua kom muaj kev nyab xeeb ntawm cov txheej txheem. Yog li ntawd, kev xaiv ntawm ib lub tog raj kheej kheej kheej yog xaiv seb lub pob valve ib txwm qhib lossis ib txwm kaw.
Lub tog raj kheej tseem ceeb yog GT lub tog raj kheej, AT lub tog raj kheej, AW thooj voos kheej kheej thiab lwm yam.
GT tshwm sim ua ntej, AT yog ib qho kev txhim kho GT, tam sim no cov khoom lag luam tseem ceeb, tuaj yeem ntsia tau nrog lub pob valve bracket dawb, sai dua li lub bracket installation, yooj yim, tab sis kuj ruaj khov dua. Txoj hauj lwm ntawm 0 ° thiab 90 ° tuaj yeem hloov kho kom yooj yim rau kev teeb tsa ntawm ntau yam solenoid li qub, stroke keyboards, handwheel mechanism accessories. AW lub tog raj kheej yog tsuas yog siv rau lub taub loj lub pob valve nrog cov zis loj zog thiab txais cov qauv piston diav rawg.
Qhov thib peb point: xaiv pneumatic accessories
Solenoid valve: Lub tog raj kheej ob lub tog raj kheej feem ntau yog nruab nrog ob txoj kev solenoid li qub lossis peb tsib-txoj kev solenoid li qub. Lub tog raj kheej nkaus xwb tuaj yeem nruab nrog ob txoj kev solenoid li qub. Voltage tuaj yeem xaiv DC24V, AC220V thiab lwm yam. Kev tawg-pov thawj yuav tsum tau xav txog.
Stroke hloov: Lub luag haujlwm yog los hloov qhov kev sib hloov ntawm tus actuator rau hauv kev sib cuag teeb liab, tso zis rau cov cuab yeej tswj, thiab tawm tswv yim txog qhov xwm txheej ntawm lub pob valve. Feem ntau siv txhua yam, sib nqus induction hom. Kev tawg-pov thawj yuav tsum tau xav txog.
Handwheel mechanism: ntsia nruab nrab ntawm lub pob valve thiab lub tog raj kheej, nws tuaj yeem hloov pauv mus rau phau ntawv hloov thaum lub tshuab cua tsis zoo los xyuas kom muaj kev nyab xeeb thiab tsis ncua kev tsim khoom.
Cov khoom siv hauv huab cua ua haujlwm: muaj ob thiab peb qhov txuas, kev ua haujlwm yog pom, txo qis, roj pos huab. Nws raug nquahu kom nruab lub cylinder los tiv thaiv lub tog raj kheej kom tsis txhob daig vim yog impurities.
Valve positioner: Rau kev hloov pauv pneumatic pob valve yuav tsum tau muab ntsia, feem ntau yog siv rau pneumatic V-hom pob valve. Sau 4-20
mA, txhawm rau txiav txim siab seb puas muaj cov lus qhia tawm tswv yim. Seb puas yuav tsum muaj pov thawj tawg. Muaj hom zoo tib yam, hom ntse.
Cov pa tawm ceev ceev: ua kom lub pneumatic pob valve hloov ceev. Nruab nruab nrab ntawm lub tog raj kheej thiab lub solenoid valve, kom cov pa roj hauv lub tog raj kheej tsis dhau los ntawm solenoid valve, tawm sai sai.
Pneumatic amplifier: Nruab nyob rau hauv txoj kev huab cua mus rau lub tog raj kheej kom tau txais lub qhov hluav taws xob qhov hluav taws xob siab teeb liab, muab cov dej ntws loj rau lub actuator, siv los txhim kho qhov ceev ntawm lub valve. 1: 1 (qhov piv ntawm cov teeb liab rau cov zis). Nws yog tsuas yog siv los xa cov paib pneumatic mus rau qhov ntev (0-300 meters) kom txo tau qhov cuam tshuam ntawm kev sib kis lag luam.
Pneumatic tuav valve: Nws yog tsuas yog siv rau kev cuam tshuam kev lag luam ntawm huab cua qhov chaw siab, thiab thaum huab cua qhov chaw siab qis dua qhov ntawd, lub valve muab cov roj xa hluav taws xob raug txiav tawm, kom lub valve tswj txoj haujlwm ua ntej huab cua tsis ua haujlwm. Thaum cov huab cua qhov siab tau rov qab los, cov cua nkag mus rau lub tog raj kheej rov pib dua tib lub sijhawm.
Pneumatic pob valve xaiv los xav txog cov yam ntxwv ntawm lub pob valve, lub tog raj kheej, cov khoom siv, txhua qhov kev xaiv ntawm qhov yuam kev, yuav muaj kev cuam tshuam rau kev siv cov pneumatic pob valve, qee zaum me me. Qee zaum cov txheej txheem yuav tsum ua tsis tau. Yog li ntawd, kev xaiv yuav tsum paub txog cov txheej txheem thiab cov kev xav tau.
