Manually tswj li qubtso siab rau tib neeg lub zog, xav kom cov neeg ua haujlwm muaj lub cev nyob rau ntawm -qhov chaw rau kev hloov kho hauv zos ntawm tes los yog tes tuav. Qhov qhib -Loop tswj tau ua rau txo qis qhov raug thiab cov lus teb ceev, thiab lawv feem ntau yog siv rau hauv cov kav dej txuas ntxiv uas cov txheej txheem tsis ruaj khov lossis rau cov khoom siv tu thiab kev sib cais.
Piv txwv li,tsis siv neeg tswj li qubsiv pneumatic, hluav taws xob, lossis hydraulic zog los tsav cov actuators, ua tiav cov chaw taws teeb kaw -loop tswj los ntawm PLC / DCS systems. Lawv muaj qhov raug hloov kho siab heev thiab millisecond- theem teb ceev, ua rau lawv yog ib feem tseem ceeb rau kev lag luam automation niaj hnub no.
Hais txog kev nyab xeeb thiab kev siv tau,tsis siv neeg tswj li qubmuaj qhov tseem ceeb "ua tsis tiav-kev nyab xeeb" ua haujlwm, rov pib dua thiab kaw lub zog tam sim thaum muaj hluav taws xob tsis ua haujlwm lossis muaj xwm txheej ceev, thiab ua kom cov neeg ua haujlwm nyob deb ntawm thaj chaw muaj kev phom sij xws li kub siab thiab tshuaj lom.
Los ntawm txhais tes li qub, ntawm qhov tod tes, tsis muaj peev xwm tiv thaiv tsis siv neeg thiab cia siab rau phau ntawv tshuaj tiv thaiv. Txawm hais tias thawj zaug kev yuav khoom thiab kev saib xyuas tus nqi ntawm cov valve tsis siv neeg siab dua, lawv qhov zoo ntawm kev tuav siab - zaus hloov pauv, ua kom cov khoom lag luam zoo sib xws, thiab kev txhim kho tag nrho cov kev nyab xeeb ua rau lawv xaiv tsis tuaj yeem hloov pauv hauv cov txheej txheem tseem ceeb.

FAQ
Lub valve tsis siv neeg tswj ua haujlwm li cas?
Cov li qubsiv cov txheej txheem dej lub zog, siab, lossis kub kom tswj tau qhov ntws. Lawv feem ntau tau nruab nrog tus kheej - muaj cov actuator, xws li lub caij nplooj ntoos hlav, diaphragm, los yog tus tsav valve, uas teb rau cov kev hloov hauv cov txheej txheem los tswj lub valve qhib.
Dab tsi yog qhov tsis zoo ntawm kev tswj valve?
Cov ntim khoom uas kaw lub qia tuaj yeem xau. Lub pneumatic lossis hluav taws xob actuator tuaj yeem ua tsis tiav. Tus positioner tuaj yeem poob nws qhov calibration thiab ua rau tus txheej txheem viav vias tawm ntawm kev tswj. Ib txwm hnav, tau cycled ntau, tsis zoo installation.
Koj xaiv lub valve li cas?
Yog tias lub kaw lus muaj cov kav dej ntau, siv qhov sib npaug feem pua.
Yog hais tias lub kaw lus muaj cov yeeb nkab me me, siv lub valve linear.
Lub valve tswj qhov loj me los ua haujlwm nyob ib puag ncig 60% mus rau 80% qhib ntawm qhov siab tshaj plaws yuav tsum tau ntws thiab tsis pub tsawg dua 20% qhib ntawm qhov tsawg kawg nkaus yuav tsum tau ntws yuav muab qhov zoo tshaj plaws tswj.
