Kungani kufaneleivalvu yomhlabaIngabe kufanele iklanywe njenge-globe valve ephansi, i-outlet ephezulu kanye ne-globe valve encane? Enqubweni yokuklama nokufaka, i-globe valve ephansi kanye ne-outlet ephezulu ivame ukusetshenziswa, okungukuthi, i-globe valve igeleza isuka ngaphansi kwe-valve flap iye ngaphezu kwe-valve flap. I-globe valve encane ine-stem torque encane kakhulu kanye ne-operation encane yokuvula nokuvala. Ngisho nangaphansi kwethonya lokucindezela okusebenzayo, umthelela ekusebenzeni mncane, ngoba ithonya lesiqondiso sokugeleza kwe-medium ebunzimeni bokusebenza lingashaywa indiva. I-globe valve encane iyamukelwa. Zonke ziyizakhiwo ezingalingani. Kungani i-globe valve kufanele iklanywe nge-inlet ephansi kanye ne-outlet ephezulu ene-inlet ephansi kanye ne-outlet ephezulu? Uma ivaliwe, ingcindezi ephakathi inomthelela omncane esiqwini se-valve futhi ngeke ithinte i-valve stem.
Isiqu se-valve sicwiliswa nakule ndawo, okungelula ukuthi idliwe yile ndawo, okuvikela ngempumelelo isiqu se-valve; isakhiwo sokupakisha siphinde sihlukaniswe ngempumelelo nale ndawo, okuqinisekisa ithonya lendawo ekupakisheni, futhi kwandise impilo yokupakisha isiqu se-valve ngempumelelo.
Into ebaluleke kakhulu ukuphepha. Uma isiqu sevalvu siphuka noma kwenzeka okunye ukwehluleka, ivalvu ingavuleka ngokuzenzakalelayo ukuvimbela ukucindezeleka ngokweqile kwesistimu.
Ukusetshenziswa kokungena okuphansi kanye nendawo yokukhipha ephezulu nakho kungagwema ngempumelelo isenzakalo sesando samanzi sevalvu yokuvala. Uma ivaliwe, ngaphansi kwesenzo sengcindezi ephakathi, isivinini sokuhamba ngaphansi kwe-flap yokugcoba asikwazi ukushesha, futhi isikhathi sokuvala side kakhulu, futhi akulula ukubangela isando samanzi ngokuthanda kwakho, okubangela ukudlidliza kwepayipi futhi kugweme ukulimala kwayo yonke imishini ehlobene nepayipi.
