Lub luag haujlwm ntawm pneumatic valve positioner Pneumatic valve yog dav siv hauv kev lag luam hluav taws xob hluav taws xob thev naus laus zis

Lub luag hauj lwm ntawm pneumatic valve positioner Pneumatic valve yog dav siv nyob rau hauv lub zog hluav taws xob technology kev lag luam Valve locator (tseem hu ua: Pneumatic valve locator) yog lub ntsiab tswj valve accessories, feem ntau nrog Pneumatic Pneumatic tswj valve, nws txais lub regulator tso zis teeb liab, thiab Tom qab ntawd mus rau nws cov teeb liab tso zis los tswj lub Pneumatic tswj valve, thaum tswj lub valve, lub valve qia ntawm kev tawm tswv yim tawm los ntawm cov cuab yeej siv rau lub valve positioner, valve txoj hauj lwm mob los ntawm hluav taws xob teeb liab mus rau sab sauv system. Valve positioner qauv: Valve positioner raws li nws cov qauv qauv thiab lub hauv paus ntsiab lus ua haujlwm tuaj yeem muab faib ua pneumatic valve positioner, hluav taws xob-gas valve positioner thiab ntse valve positioner. Valve positioner tuaj yeem ua kom lub zog tso tawm ntawm lub valve tswj, txo qis kev sib kis ntawm lub teeb liab tswj, ua kom lub zog ceev ntawm lub valve qia, tuaj yeem txhim kho cov kab ntawm lub valve, kov yeej kev sib txhuam ntawm lub valve qia thiab tshem tawm cov kev cuam tshuam ntawm lub valve. lub zog tsis sib npaug, thiaj li ua kom qhov tseeb qhov chaw ntawm lub regulating valve. Valve positioner ADAPTS ntau yam nquag siv actuators muab faib ua pneumatic actuators, hluav taws xob actuators, ncaj stroke, Angle stroke. Siv los qhib thiab kaw txhua yam li qub thiab cov paib cua tau txais thiab manually. Lub hauv paus ntsiab lus ua haujlwm ntawm valve positioner Lub valve positioner yog cov khoom tseem ceeb ntawm kev tswj lub valve. Nws yuav siv lub valve qia tshem tawm teeb liab raws li cov lus qhia tawm tswv yim ntsuas teeb liab, siv lub teeb liab tso zis hluav taws xob raws li lub teeb liab teeb liab, sib piv, thaum ob qhov sib txawv, hloov nws cov teeb liab tawm mus rau tus actuator, ua rau lub actuator ua, tsim lub valve qia. Lub sij hawm hloov chaw thiab cov khoom siv hluav taws xob tso tawm ntawm qhov sib txuas lus ib-rau-ib. Yog li ntawd, lub valve positioner muaj lub tswv yim tswj qhov system nrog lub qia txav raws li qhov ntsuas teeb liab thiab cov khoom tso tawm raws li lub teeb liab teeb liab. Kev tswj qhov sib txawv ntawm kev tswj qhov system yog lub teeb liab tso tawm ntawm lub valve positioner rau tus actuator. Kev faib tawm ntawm valve positioners Valve positioner muab faib ua pneumatic valve positioner thiab hluav taws xob valve positioner raws li cov teeb liab tawm tswv yim. Lub tswv yim teeb liab ntawm pneumatic valve positioner yog tus qauv roj teeb liab, piv txwv li, 20 ~ 100kPa roj teeb liab, nws cov teeb liab tso tawm kuj yog cov teeb liab roj teeb. Lub tswv yim teeb liab ntawm hluav taws xob valve positioner yog tus qauv tam sim no lossis voltage teeb liab, piv txwv li, 4 ~ 20mA tam sim no teeb liab lossis 1 ~ 5V voltage teeb liab, thiab lwm yam. cov zis gas teeb liab mus rau toggle tswj valve. Raws li kev taw qhia ntawm qhov kev txiav txim tuaj yeem muab faib ua ib-txoj kev valve positioner thiab ob-txoj kev valve positioner. Lub ib-txoj kev valve positioner yog siv nyob rau hauv lub piston actuator, lub valve positioner tsuas yog ua hauj lwm nyob rau hauv ib tug kev taw qhia, ob txoj kev valve positioner ua hauj lwm nyob rau hauv ob sab ntawm lub tog raj kheej ntawm lub piston actuator, nyob rau hauv ob txoj kev. Raws li lub valve positioner tso zis thiab input teeb liab nce lub cim yog muab faib ua zoo valve positioner thiab cov tshuaj tiv thaiv valve positioner. Raws li cov tswv yim teeb liab mus rau qhov zoo-ua yeeb yam valve positioner nce, cov zis teeb liab kuj nce, yog li qhov nce yog qhov zoo. Reaction valve positioner input teeb liab nce, cov teeb liab tso zis tsawg, yog li ntawd, qhov nce yog qhov tsis zoo. Raws li lub valve positioner input signal yog analog teeb liab lossis digital teeb liab, tuaj yeem muab faib ua qhov zoo tib yam valve positioner thiab lub tsheb npav hluav taws xob valve positioner. Lub teeb liab input ntawm lub hom valve locator yog analog siab lossis tam sim no, voltage teeb liab, lub teeb liab input ntawm fieldbus hluav taws xob valve locator yog cov teeb liab ntawm lub fieldbus. Raws li seb lub valve positioner muaj CPU, nws tuaj yeem muab faib ua hluav taws xob zoo tib yam valve positioner thiab ntse hluav taws xob valve positioner. Feem ntau cov hluav taws xob valve positioners tsis muaj CPU, yog li ntawd, tsis muaj kev txawj ntse, tsis tuaj yeem tswj cov haujlwm ntse. Intelligent valve positioner nrog CPU, tuaj yeem tswj cov kev ua haujlwm ntse, piv txwv li, tuaj yeem nqa mus tom ntej channel nonlinear them nyiaj, thiab lwm yam., fieldbus hluav taws xob valve positioner kuj tuaj yeem nqa Pneumatic li qub tau siv dav hauv kev lag luam hluav taws xob thev naus laus zis ua raws li qhov ceev ntawm hluav taws xob. lub zog hluav taws xob tshuab hluav taws xob thiab tsis siv neeg tswj valve kev lag luam, thiab kev tsim hluav taws xob valve actuators kuj tau ua ib kauj ruam, txhua thib ob hauv cov khoom ntse ntse kuj tseem maj mam tshwm sim, thaum lub sij hawm tag nrho cov khoom siv tswj kev lag luam ntawm tam sim no kuj coj mus rau lub khw muag khoom. yuav muaj tseeb pab, kuj tau txais ntau tus phooj ywg, pneumatic valve Txoj kev loj hlob ntawm pneumatic valve actuator tau maj mam txhim kho. Tus nqi qis ib nti microcomputer thiab cov ntawv ceeb toom tshiab microprocessor yuav hloov cov khoom siv hluav taws xob siv hluav taws xob los ua qhov tseem ceeb ntawm lub tshuab hluav taws xob valve actuator, thiab tom qab ntawd ua tiav cov kev tswj hwm digital. Ua raws li qhov ceev ntawm hluav taws xob hluav taws xob hluav taws xob tshuab hluav taws xob thiab tsis siv neeg tswj valve kev lag luam, thiab kev txhim kho ntawm hluav taws xob valve actuators kuj tau ua ib kauj ruam dhau los, txhua qhov thib ob hauv cov khoom siv ntse ntse kuj tseem maj mam tshwm sim, thaum lub sijhawm ntawd tag nrho cov cuab yeej tswj kev lag luam ntawm tam sim no kuj nqa mus rau lub khw yuav pab tau, kuj tau txais ntau tus phooj ywg, pneumatic valve Txoj kev loj hlob ntawm pneumatic valve actuator tau maj mam txhim kho. Tus nqi qis ib nti microcomputer thiab cov ntawv ceeb toom tshiab microprocessor yuav hloov cov khoom siv hluav taws xob siv hluav taws xob los ua qhov tseem ceeb ntawm lub tshuab hluav taws xob valve actuator, thiab tom qab ntawd ua tiav cov kev tswj hwm digital. Kev lig kev cai ntawm cov khoom siv thiab cov yam ntxwv los ntawm kev ua haujlwm ntawm cov khoom ntse niaj hnub no tsis muaj qhov nthuav dav ntawm qhov yooj yim thiab ib qho yooj yim ntawm lub sijhawm khiav, qhov tseeb, feem ntau ntawm valve actuators yuav tawm tsam qhov kev hloov pauv pom tseeb, tau kawg ntawm kev teem sijhawm thiab cov qauv ntsuas kev txheeb xyuas los ntawm kev tswj nruab nrab. yuav * * los txhim kho kev tswj kev ua haujlwm ntawm hluav taws xob valve actuators. txheeb ze rau pneumatic thiab hydraulic li qub, yooj yim thaiv thiab muaj zog muaj nuj nqi thiab txuas ntxiv nthuav dav ntawm kev siv. Vim hais tias lub pneumatic valve nyob rau hauv cov yeeb nkab network feem ntau yog qhib thiab kaw infrequently, lub packing tsis laus los tuav lub sealing nyhuv rau lub sij hawm ntev.
