Valavu yamagetsi
Ma valve amagetsi amagwiritsidwa ntchito makamaka m'mafakitale amagetsi kapena m'mafakitale amagetsi a nyukiliya, chifukwa makina amadzi opanikizika kwambiri amafuna njira yosalala, yokhazikika komanso yochedwa. Ubwino waukulu wa ma actuator amagetsi ndi kukhazikika kwakukulu komanso kukakamiza kosalekeza komwe ogwiritsa ntchito angagwiritse ntchito. Kukakamiza kwakukulu komwe kumapangidwa ndi actuator kumatha kufika 225000kgf. Ma hydraulic actuator okha ndi omwe angakwaniritse kukakamiza kwakukulu kotere, koma mtengo wa ma hydraulic actuator ndi wapamwamba kuposa wamagetsi. Mphamvu yotsutsana ndi kupotoka kwa actuator yamagetsi ndi yabwino kwambiri, kukakamiza kapena torque yotulutsa imakhala yokhazikika, yomwe imatha kuthana ndi mphamvu yosalinganika ya medium ndikupeza kuwongolera kolondola kwa magawo a process, kotero kulondola kowongolera kumakhala kokulirapo kuposa kwa actuator ya pneumatic. Ngati ili ndi servo amplifier, zotsatira zabwino ndi zoyipa zitha kusinthidwa mosavuta, ndipo mkhalidwe wa valavu yoyimitsa chizindikiro (kugwira/kutsegula kwathunthu/kutseka kwathunthu) ukhoza kukhazikitsidwa mosavuta, ndipo cholakwika chikachitika, chiyenera kukhala pamalo oyamba. Izi ndi Pneumatic actuators sizingathe kuchita izi. Ma actuator a pneumatic ayenera kudalira njira yotetezera yogwirizana kuti asunge malo awo. Zoyipa zazikulu za ma actuator amagetsi ndi izi:
Kapangidwe kake ndi kovuta kwambiri, ndipo kamalephera kutha. Chifukwa cha zovuta zake, zofunikira zaukadaulo za ogwira ntchito yokonza pamalopo zimakhala zapamwamba kwambiri; mota imagwira ntchito kuti ipange kutentha. Ngati kusinthako kuli kofala kwambiri, n'zosavuta kupangitsa mota kutentha kwambiri ndikupanga chitetezo cha kutentha. Nthawi yomweyo, idzawonjezera kuwonongeka kwa zida zochepetsera; kuphatikiza apo, imayenda pang'onopang'ono. Zimatenga nthawi yayitali kuchokera pa kutulutsa kwa chizindikiro kuchokera ku regulator kupita ku kayendedwe ka valavu yowongolera kupita kumalo ofananira poyankha. Izi zili choncho chifukwa si yabwino ngati pneumatic ndi hydraulic. Malo a actuator.
Ma valve a pneumatic
Choyatsira ndi njira yosinthira ya choyatsira mpweya cha valavu ndi chinthu chogwirizana, ndipo choyatsira mpweya chili ndi mitundu iwiri: mtundu wa nembanemba ndi mtundu wa pistoni. Mtundu wa pistoni uli ndi sitiroko yayitali ndipo ndi yoyenera nthawi zomwe zimafuna kukankhidwa kwakukulu; pomwe mtundu wa nembanemba uli ndi sitiroko yaying'ono ndipo imatha kuyendetsa mwachindunji tsinde la valavu. Chifukwa choyatsira mpweya cha pneumatic chili ndi ubwino wa kapangidwe kosavuta, kukankhidwa kwakukulu kotulutsa, kuchitapo kanthu kokhazikika komanso kodalirika, komanso chitetezo ndi kuphulika, chili ndi ntchito zambiri m'mafakitale amphamvu, mafakitale a mankhwala, kuyeretsa mafuta ndi njira zina zopangira zomwe zimafunikira chitetezo chambiri.
Ubwino waukulu wa ma actuator a pneumatic:
Landirani chizindikiro cha mpweya chopitilira ndi kusuntha kwa mzere wotuluka (pambuyo pa chipangizo chosinthira magetsi/mpweya, chizindikiro chamagetsi chopitilira chingalandiridwenso), ndipo zina zimatha kutulutsa kusuntha kwa angular zikakhala ndi mkono wogwedezeka.
Pali ntchito zabwino ndi zoipa.
Liwiro la kuyenda ndi lalikulu, koma liwiro lidzachepa pamene kuwonongeka koipa kukuwonjezeka.
Mphamvu yotulutsa imagwirizana ndi kuthamanga kwa ntchito.
Kudalirika kwake n'kwapamwamba, koma valavu singathe kusungidwa mpweya utasokonekera (ikhoza kusungidwa mutawonjezera valavu yosungira).
Ndikovuta kuchita zinthu zowongolera magawo ndi kuwongolera pulogalamu.
Kusamalira n'kosavuta, ndipo kusinthasintha malinga ndi chilengedwe n'kwabwino.
Mphamvu yotulutsa ndi yayikulu. Ili ndi ntchito yoteteza kuphulika.

Nortech ndi m'modzi mwa opanga ma valve otsogola ku China omwe ali ndi satifiketi ya ISO9001 yapamwamba.

Zinthu zazikulu:Valavu ya Gulugufe,Valavu ya Mpira,Valavu ya Chipata,Valavu Yowunikira,Globe Vavlve,Zipangizo za Y,Chotsukira Magetsi,Zipangizo zoyezera mpweya (Pneumatic Acurators).
