HITORK Pneumatic control valve ndi gawo lanzeru kwambiri popanga.M'dongosolo lowongolera, valavu yowongolera pneumatic idzawoneka ngati ikugunda.Ndiye zotsatira za kukangana kwa ma valve owongolera pneumatic ndi chiyani?
Kugonjetsa kukangana ndi imodzi mwa ntchito zoyamba za valve positioner.Kukangana kwa valavu yowongolera makamaka kumachokera ku magawo awiri: kulongedza ndi mphete yosindikizira ya manja.Ngati tsinde silosalala kapena kulongedza kwake kuli kolimba kwambiri, kukangana pakati pa tsinde ndi kunyamula kumatha kukhala kopitilira muyeso.Panyengo ya kutentha kwambiri, kusokoneza kofananira kwa mphete ya graphite ndi manja kumagwiritsidwa ntchito kuti valavu yoyang'anira ikwaniritse zofunikira zosindikiza.Ngati kusokoneza kuli kwakukulu kwambiri kapena ellipse ya manja ndi yaikulu kwambiri, kukangana pakati pa spool ndi manja kumakhala kwakukulu kwambiri.Chifukwa chakuti mphamvu ya static friction ndi yaikulu kwambiri kuposa kukangana kosunthika, pamtunda wa zochitika zambiri, valve idzalumpha, yomwe imadziwikanso kuti peristalsis.Kusinthasintha kwake kuli motere: pamene kusintha kwa ma telesignal (ie siginecha) kumachitika, kupatuka kobwera chifukwa cha kukangana kumakhala kwakukulu, ndipo zotsatira zonse za choyikapo zimangowonjezera zotulutsa.Pamene static friction mphamvu ikuwonjezeka mokwanira kuti igonjetse, valavu imagwira ntchito.Chifukwa kukangana kosasunthika ndikokulirapo kuposa kukangana kosunthika, mavavu amadumphira, kupatuka koyipa kumakhala kupatuka kwabwino.Dongosololi ndi lovuta kukhazikika chifukwa chakupitilira mobwerezabwereza.Poganizira vuto la kukangana, ena opanga ma shifter amapanga ma aligorivimu amphamvu kwambiri, omwe amachepetsa kwambiri kusinthasintha kwa ma valve.
