Iivalvu zokukhupha eziFlanged
Iimbonakalo
▪ Ukusebenza ngokulula, ukuvula simahla, ukuguquguquka nokuhamba okuthembekileyo.
▪ Ukudityaniswa kwediskhi yevalve elula kunye nokugcinwa, ulwakhiwo lokutywina olufanelekileyo, ukutshintshwa kweringi yokutywina ngokufanelekileyo nangokusebenzisekayo.
▪ Ulwakhiwo: Ikakhulu ibandakanya umzimba wevalvu, idiskhi yevalvu, iringi yokutywina, isiqu sevalvu, isibiyeli, idlala lesivalo, ivili lesandla, iflange, inati, isikrufu sokumisa kunye namanye amalungu.
▪ Olu hlobo lwevalve yokukhupha kufuneka ngokubanzi lufakwe ngokuthe tye kumbhobho.

Umahluko phakathi kweeValves eziKhuphayo eziSasaza phezulu kunye neeValufa eziSasaza ezantsi
Ukuvula kunye nokuvala i-stroke
▪ Imivumbo yokuvula nokuvala yahlukile.Kwaye imilinganiselo yokufakela yahlukile.I-stroke yokuvula kunye nokuvala i-valve yokukhupha i-valve ephezulu incinci, kwaye ukuphakama kofakelo kuncinci.Ukuphakama kofakelo lwesakhiwo sentonga ejikelezayo yincinci.I-plunger ijikeleza kuphela ngexesha lokuvula kunye nenkqubo yokuvala.Kuxhomekeke kwisalathisi sokuvula kunye nokuvala indawo yokugweba indawo yokuvula kunye nokuvala i-valve.
Ukuvula kunye nokuvala itorque
▪ Ivalve ekhuphayo yohlobo olunyukayo ivula ivalve ngokuyisa idiskhi phezulu.Xa uvula, i-valve idinga ukunqoba amandla ophakathi, kwaye i-torque yokuvula inkulu kune-torque yokuvala.
▪ Uhlobo lolwandiso oluya ezantsi kunye nohlobo lokukhupha ivelufa yivalve disc (plunger) eyehla ezantsi ukuvula ivalve.Xa ivuliwe, isalathiso sokuhamba siyafana namandla ophakathi, ngoko xa ivuliwe, i-torque yokuvala incinci.
