Koj puas paub lub hom phiaj ntawm hluav taws xob tswj valve?

Hluav taws xob tswj valve yog ib qho cuab yeej tseem ceeb hauv cov txheej txheem ntawm kev lag luam automation. Nrog rau kev txhim kho kev lag luam automation, ntau thiab ntau daim ntawv thov raug siv nyob rau hauv ntau yam kev lag luam ntau lawm. Piv nrog cov khoom siv pneumatic tswj li qub, nws muaj qhov zoo tshaj plaws: txuag hluav taws xob (tsuas yog siv hluav taws xob thaum ua haujlwm), kev tiv thaiv ib puag ncig (tsis muaj cov pa roj carbon emissions), ceev thiab yooj yim (tsis muaj qhov nyuaj pneumatic pipelines thiab cua twj tso kua mis workstations). Raws li cov haujlwm tseem ceeb thiab cov yam ntxwv ntawm lub valve, nws tuaj yeem muab faib ua peb pawg: cov yam ntxwv linear, cov yam ntxwv sib luag, thiab cov yam ntxwv parabolic.

Los ntawm kev tau txais cov teeb liab ntawm kev lag luam automation tswj qhov system (xws li 420mA), lub valve yog tsav los hloov thaj tsam ntawm lub valve core thiab lub rooj zaum valve, tswj qhov ntws, kub, siab, thiab lwm yam txheej txheem tsis siv neeg, thiab paub txog qhov tsis siv neeg. kev hloov kho muaj nuj nqi. Lub actuator ntawm tus tshiab hluav taws xob tswj valve muaj kev ua haujlwm pub mis, lees txais kev sib koom ua ke 4-20}mA lossis 1-5 DC tus qauv teeb liab, hloov cov teeb liab tam sim no rau hauv cov kab sib txuas sib txuas, tswj tau qhib qhov tswj valve. , thiab paub txog qhov kev hloov pauv tas mus li ntawm cov txheej txheem tsis xws li siab, ntws, kub, thiab qib kua dej hauv cov kav dej. Lub luag haujlwm tseem ceeb ntawm lub tshuab hluav taws xob tswj valve yog kev tswj hwm, uas feem ntau cuam tshuam txog tsib yam. Nws cov yam ntxwv ntws qhia txog kev sib raug zoo ntawm kev qhib lub valve tswj thiab ntws. Cov yam ntxwv ntws qhia txog kev tswj xyuas qhov zoo ntawm cov hluav taws xob valve. Qhov kev tswj hwm ntau R qhia txog qhov kev tswj tau ntws ntawm cov tswj valve, uas yog qhia los ntawm qhov piv r=gmaxqmin. Qhov loj dua R-tus nqi, qhov loj dua qhov kev hloov pauv tau ntau thiab qhov ua tau zoo dua qhov Performance index.

Feem ntau, r=30, thiab lub valve zoo, xws li V-hom pob valve, puv-function ultra-light regulating valve, tuaj yeem ncav cuag 100-200. Ib qho zoo me me qhib valve yuav tsum muaj kev tswj xyuas zoo. Qee lub valve raug txwv los ntawm cov qauv, nrog kev ua haujlwm tsis zoo, kev dhia me me thiab kev vibration, thiab R (uas yog, Q min) yog qhov loj heev, xws li ob lub rooj sib tw roj hmab tawm valve. Ib qho zoo me me qhib valve yuav tsum muaj kev ua haujlwm zoo kom ua tau raws li cov kev cai me me thiab kev ua haujlwm. Kev sib npaug heev, xws li V-hom pob valve, eccentric rotation, full-function ultra-light electric valve, thiab lwm yam. Cov flow coefficient KV qhia tias muaj peev xwm dhau qhov ntws. Qhov loj dua tus nqi Kv ntawm tib lub caliber, qhov zoo dua. Tshwj xeeb tshaj yog rau cov pob li qub, npauj npaim li qub, thiab lub teeb ua haujlwm puv nkaus li qub, tus nqi Kv yog 2-3 zaus ntawm ib lub rooj li qub, ob lub rooj zaum li qub, thiab lub tes tsho li qub. Kho qhov ceev kom ua tau raws li qhov kev xav tau ceev ntawm lub valve.
