Intelligent Valve electro-pneumatic Positioner
Valve positioner, lub ntsiab accessory ntawm lub regulating valve, lub valve positioner yog lub ntsiab accessory ntawm lub regulating valve, uas yog siv los tswj qhov qhib degree ntawm pneumatic los yog hluav taws xob valve kom ntseeg tau tias lub valve tuaj yeem nres kom raug thaum nws mus txog qhov kev txiav txim siab. txoj hauj lwm. Los ntawm kev tswj xyuas meej ntawm lub valve positioner, qhov kev hloov pauv ntawm cov kua dej tuaj yeem ua tiav kom tau raws li qhov xav tau ntawm ntau yam kev lag luam. Valve positioners tau muab faib ua pneumatic valve positioners, electro-pneumatic valve positioners thiab ntse valve positioners raws li lawv cov qauv. Lawv tau txais cov teeb liab tso zis ntawm lub regulator thiab tom qab ntawd siv lub teeb liab tso zis los tswj lub pneumatic regulating valve. Qhov kev hloov ntawm lub qia valve yog pub rov qab mus rau lub valve positioner los ntawm cov khoom siv tshuab, thiab lub valve txoj hauj lwm raug xa mus rau sab sauv los ntawm lub teeb liab hluav taws xob.Pneumatic valve positioners yog hom yooj yim tshaj plaws, tau txais thiab pub rov qab cov teeb liab los ntawm cov khoom siv tshuab.
Electro-pneumatic valve positioner muab cov khoom siv hluav taws xob thiab cov tshuab pneumatic los txhim kho qhov tseeb thiab kev tswj tau yooj yim.
Qhov ntse valve positioner qhia microprocessor thev naus laus zis kom ua tiav automation siab dua thiab ntse tswj.
Valve positioners ua lub luag haujlwm tseem ceeb hauv kev lag luam automation, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas yuav tsum tau muaj kev tswj xyuas cov kua dej, xws li tshuaj lom neeg, roj av, thiab kev lag luam roj. Lawv tau txais cov cim qhia los ntawm kev tswj hwm qhov system thiab kho kom raug qhov qhib ntawm lub valve, yog li tswj cov dej ntws thiab ua tau raws li qhov xav tau ntawm ntau yam kev lag luam. -
txwv hloov lub thawv-Valve Position Monitor-travel switch
Lub valve txwv hloov lub thawv, tseem hu ua Valve Position Monitor lossis valve mus txawv tebchaws, yog ib qho cuab yeej siv los kuaj xyuas thiab tswj qhov qhib thiab kaw txoj haujlwm ntawm lub valve. Nws muab faib ua txhua yam thiab sib thooj hom. peb cov qauv muaj Fl-2n, Fl-3n, Fl-4n, Fl-5n. Qhov txwv hloov lub thawv tawg-pov thawj thiab tiv thaiv qib tuaj yeem ua tau raws li cov qauv hauv ntiaj teb.
Mechanical limit switches tuaj yeem muab faib ntxiv rau hauv kev ua yeeb yam ncaj qha, dov, micro-motion thiab sib xyaw ua ke raws li kev ua haujlwm sib txawv. Mechanical valve txwv keyboards feem ntau yog siv micro-txoj kev hloov pauv nrog cov neeg tsis muaj zog, thiab lawv cov ntaub ntawv hloov pauv suav nrog ib tus ncej ob-thib (SPDT), ib tus ncej ib zaug pov (SPST), thiab lwm yam.
Cov kev txwv qhov sib thooj, tseem hu ua contactless mus txawv tebchaws keyboards, sib nqus induction valve txwv keyboards feem ntau siv electromagnetic induction sib thooj keyboards nrog passive hu. Nws cov ntaub ntawv hloov pauv muaj xws li ib leeg-ncej ob-thib (SPDT), ib leeg-ncej ib leeg-tso (SPST), thiab lwm yam.
