Pneumatic Actuator Tswj Globe Valve
✧ Nqe lus piav qhia
Pneumatic tswj lub ntiaj teb valve tseem hu ua pneumatic cut-off valve, yog ib yam ntawm actuator nyob rau hauv lub automation system, muaj ntau lub caij nplooj ntoos hlav pneumatic zaj duab xis actuator los yog floating piston actuator thiab regulating valve, tau txais lub teeb liab ntawm regulating ntsuas, tswj lub txiav tawm. , txuas lossis hloov cov kua hauv cov txheej txheem kav dej. Nws muaj cov yam ntxwv ntawm cov qauv yooj yim, cov lus teb rhiab thiab txhim khu kev qha. Nws tuaj yeem siv dav hauv roj av, tshuaj lom neeg kev lag luam, metallurgy thiab lwm yam kev lag luam ntau lawm. Cov huab cua ntawm lub pneumatic txiav tawm valve yuav tsum tau lim compressed cua, thiab qhov nruab nrab ntws los ntawm lub valve lub cev yuav tsum tsis muaj impurities thiab hais txog cov kua thiab roj.
Lub tog raj kheej ntawm lub ntiaj teb pneumatic valve yog cov khoom lag luam stereotyped, uas tuaj yeem muab faib ua ib qho kev txiav txim thiab ob qho kev txiav txim raws li hom kev ua. Cov khoom lag luam ib leeg muaj qhov rov pib lub tog raj kheej caij nplooj ntoos hlav, uas muaj qhov tsis siv neeg rov pib ua haujlwm ntawm huab cua poob, uas yog, thaum lub tog raj kheej piston (los yog diaphragm) nyob rau hauv qhov kev txiav txim ntawm lub caij nplooj ntoos hlav, lub tog raj kheej thawb pas nrig yog tsav rov qab mus rau qhov pib. txoj hauj lwm ntawm lub tog raj kheej (tus thawj txoj hauj lwm ntawm tus mob stroke). Lub tog raj kheej ob lub tog raj kheej tsis muaj lub caij nplooj ntoos hlav rov qab, thiab kev ua ntej thiab kev tawm ntawm lub thawb pas nrig yuav tsum nyob ntawm qhov chaw nkag thiab qhov hluav taws xob ntawm lub tog raj kheej cua. Thaum cov huab cua nkag mus rau sab sauv ntawm lub piston, lub thawb pas nrig txav mus rau hauv qab. Thaum cov huab cua nkag mus rau hauv qab kab noj hniav ntawm lub piston, lub laub pas nrig txav mus rau pem hauv ntej. Vim tias tsis muaj lub caij nplooj ntoos hlav rov pib dua, lub tog raj kheej ob lub tog raj kheej muaj zog ntau dua li lub tog raj kheej kheej kheej kheej kheej, tab sis nws tsis muaj qhov tsis siv neeg rov pib dua. Pom tseeb, qhov sib txawv ntawm qhov nqus tau ua rau lub putter txav mus rau qhov sib txawv. Thaum cov cua nkag mus rau hauv lub nraub qaum ntawm lub laub pas nrig, cov cua nkag ua rau lub laub pas nrig ua ntej, txoj kev no hu ua lub tog raj kheej zoo. Ntawm qhov tsis sib xws, thaum cov cua nkag mus rau ntawm tib sab ntawm lub laub pas nrig, cov cua nkag ua rau lub log thawb rov qab, uas yog hu ua cov tshuaj tiv thaiv lub tog raj kheej. Pneumatic lub ntiaj teb valve vim hais tias qhov dav dav yuav tsum poob huab cua tiv thaiv kev ua haujlwm, feem ntau yog siv ib lub tog raj kheej ua yeeb yam.

✧ Qhov zoo ntawm Pneumatic Actuator Control Globe Valve
Thaum lub sij hawm qhib thiab kaw txheej txheem ntawm forged steel ntiaj teb valve, vim hais tias kev sib txhuam ntawm lub disc thiab sealing nto ntawm lub valve lub cev yog me dua li ntawm lub rooj vag valve, nws yog hnav-resistant.
Qhov qhib lossis kaw stroke ntawm lub valve qia yog luv luv, thiab nws muaj kev txhim khu kev qha kev txiav tawm, thiab vim hais tias qhov kev hloov ntawm lub rooj zaum qhov chaw nres nkoj valve yog proportional rau stroke ntawm lub valve disc, nws yog heev haum rau kev hloov. ntawm tus nqi ntws. Yog li ntawd, hom valve no yog qhov tsim nyog rau kev txiav tawm lossis kev tswj hwm thiab throttling.
