Pneumatic valve yog ib qho khoom siv tswj nrog tsav cua. Vim tias nws txoj kev ntseeg siab, hloov ceev nrawm nrawm, nyab xeeb kev nyab xeeb thiab tawg-pov thawj, nws tau dav siv roj, chav, kua thiab lwm yam xov xwm tsis muaj kev kho tshwj xeeb. Pneumatic valve yog nruab nrog cov khoom sib txawv ntsig txog, hloov chaw tuaj yeem pom tau thiab txawj ntse hloov-ob txoj haujlwm! Rau ob qhov sib txawv ntawm kev tswj ntsuas valve, kev siv qhov chaw tsis zoo li qub, tuaj yeem tsis meej pem.
Pneumatic cut-off valve feem ntau yog lub raj xa dej nruab nrab kom qhib thiab kaw lub luag haujlwm ntawm lub ntsiab valve txoj haujlwm qhib thiab kaw txoj haujlwm, feem ntau siv rau qhov kev xav tau sai rau txoj haujlwm, feem ntau rau cov raj xa dej hauv ib txwm qhib lub xeev, kaw nrawm ntawm qhov xwm txheej ceev! Lub tshuab pneumatic tswj lub chaw tsis muaj kev txwv, thiab cov cuab yeej rau khoom siv, cov lus taw qhia 4 ~ 20mADC thiab cov pa roj tuaj yeem tswj tau qhov kev ua haujlwm, siab, ntws, kub, kua thiab lwm yam kev ntsuas ntawm txoj cai!
Pneumatic cut-off valve thiab pneumatic tswj qhov sib txawv valve:
1, lub pneumatic valve, suav nrog lub tswj valve thiab lub qhov rooj sib txuas, lub luag haujlwm ntawm ob daim ntawv tsis zoo ib yam, txawm hais tias cov kev tswj ntws tau tuaj yeem hloov kho rau 0, tab sis lub tshuab kaw hluav taws xob feem ntau siv rau thaum muaj xwm ceev kaw-kaw, nrog lub valve positioner, feem ntau yog lub tog raj kheej valve. Tus tswj lub valve yog nrog pneumatic zaj duab xis, qhov zoo ntawm lub disc loj, ntxiv rau txhawm rau kho, tab sis kuj tuaj yeem txiav tawm, qhov txawv ntawm ob qhov tsuas yog cov roj av.
2, pneumatic cut-off valve yog qhib tag nrho lossis kaw, ntau rau kev tiv thaiv; thiab pneumatic tswj lub valve tuaj yeem hloov mus rau txhua txoj haujlwm, tswj lub valve kom nyob ntawm qhov kev qhib tshwj xeeb, koj tuaj yeem kho qhov ntws lossis siab. Pneumatic kaw-kaw valve siv los kaw cov xov xwm raj, xav kom ua haujlwm ceev, kaw qhov kev sib khi zoo dua, qib dej ntws tawm kom ncav cuag ib puas txhiab.
3, pneumatic tswj valve feem ntau yog siv rau kev tswj xyuas tas mus li, lub teeb liab thiab lub teeb pom kev zoo sib thooj nrog hluav taws xob valve txoj hauj lwm kom tau txais cov qauv tswj, raws li nruam 4-20MA teeb liab hloov, tswj lub valve kom ua tiav 0-100% ntawm tag nrho cov kev nqis tes ua. Cov.
4, Pneumatic cut-off valve tsuas yog qhib thiab kaw ob txoj haujlwm, feem ntau nrog thim rov qab solenoid valve thiab hloov mus ncig, solenoid valve siv los hloov cov kev taw qhia ntawm pneumatic actuator, taug kev mus rau cov lus taw qhia lub kaw lus rau kev tswj hwm, nkag siab lub sijhawm tiag tiag ntawm tus saib xyuas txoj hauj lwm valve. Pneumatic tswj lub valve tuaj yeem kaw thaum muaj qee tus nqi ntawm cov xau, pneumatic cut-off valve yog qhov yuav tsum tau xoom lossis ze rau xoom.
