Uma i-valve kufanele ikhethwe ngezimo eziphakeme zokushisa, impahla kufanele ikhethwe ngokufanele. Izinto ezisetshenziswayo zama-valve zizokwazi ukumelana nezimo zokushisa eziphakeme futhi zihlale zizinzile ngaphansi kwesakhiwo esifanayo. Ama-valve emazingeni okushisa aphezulu kufanele abe ngokwakhiwa okuqinile. Lezi zinto zingaba insimbi engagqwali yekhwalithi ephezulu kanye nensimbi engagqwali enezinhlangothi ezimbili. Izinto ezisezingeni eliphansi ezizothinta ukuhlangana kwezinga lokushisa akufanele zisetshenziswe, ngaphandle kwalokho ama-deformation noma ama-valve ezinto ezinwabuzelayo azogwenywa.

Izimo zokushisa eziphezulu

Ama-valve uvemvane i-throttle angase azinze ngaphansi kwezinga lokushisa eliphezulu. Isakhiwo kanyeumzimba we-valveizocatshangelwa kanye ne-radiator ukuze ikwazi ukusikwa ngezinto zokubeka ukushisa. Uma i-valve ibhekwa, impahla ye-valve ayizinzile. Uma izinga lokushisa lidlula umkhawulo i-valve engakwazi ukumelana nayo, ngeke ifanele i-valve yakho.

Kumelwe ucabangele ama-valve anamapayipi e-ceramic noma amanye ama-valve anamajakhethi okupholisa ukuze ulinganisele imiphumela yezimo zokushisa. Lawa mabhantshi okupholisa asebenza ngokujikeleza kwamanzi abandayo. Ngakho-ke, indabaku-valveizolinganiswa ngaphandle kokucindezeleka komkhawulo ongaphezulu.

Izimo zokushisa eziphansi

Uma izinga lokushisa liphansi kakhulu, njenge -29℃, i-valve ene-coefficient yokumelana nokushisa okuphansi kufanele ikhethwe. Ezingeni lokushisa eliphansi kakhulu - 29 kuya - 196 degrees Celsius, igobolondo nezinto zokunquma zinokuqina okwanele ukugcina ukushisa nokulinganisa imiphumela yamazinga okushisa aphansi kakhulu.

Kulesi simo sokushisa esiphansi, kufanele ukhethe i-valve enempahla yokugcwalisa kanye nesigaba sethangi lamanzi ukuze ulawule isidingo sokushisa. Ukukhethwa kwalawa ma-valve kwenza izimo zokushisa zigcinwe ngaphezu kuka-0℃.

Ukuqapha emazingeni okushisa ahlukene

Kukhona okukodwa okuhlukile ezinyathelweni zevalvu. Lapho i-valve ivaliwe, uketshezi oluthile egunjini le-valve luzohlala luvaliwe. Ngokuhamba kwesikhathi, uketshezi oluthile luzohlala ekamelweni le-valve. Ngakho-ke, ukushisa kuzothathwa kancane kancane umkhathi futhi kuphinde kufinyelele izimo zokushisa ezifanayo, noma kuhwamuke ekamelweni le-valve.

Uma lokhu kwenzeka, ivolumu izokhuphuka izikhathi ezingaba ngu-600, okuzoletha ingcindezi emangalisayo emzimbeni we-valve. Lokhu kucindezeleka okuphezulu noma ukucindezela emzimbeni we-valve kubizwa ngokuthi inani lokucindezela okungavamile. Lesi simo asilawuleki, ngakho singabangela izinkinga ezinkulu ze-valve futhi singase sibe imbangela yengozi.

Ukuze ugweme lokhu okuhlangenwe nakho okungathandeki kwe-valve ngaphansi kwezimo eziningi zokushisa, kufanele ukhethe i-valve ene-orifice ehlelwe kahle. Lolu hlobo lwe-valve luvame ukusetshenziswa kuleli cala, futhi le ndlela isetshenziswa kabanzi kulo mkhakha.

imfuneko yokusebenza

Okokuqala, kufanele uchaze zonke izidingo zesimo sokushisa nezingcindezi. Kufanele usho izinga lokushisa nobubanzi bengcindezi yevalvu ofuna ukuyisebenzisa. Kuzokusiza ukuthi ukhethe i-valve yezinto ezibonakalayo efanelekayo okushisa okuhlukene. Ake sithi ufuna ukusebenzisa le valve ekushiseni okuphezulu. Kulesi simo, kunconywa ukusebenzisa i-valve yensimbi ngoba ingakwazi ukumelana nezimo zokushisa eziphakeme kunanoma iyiphi enye into. Uma igesi noma ingcindezi ye-liquid ku-valve iphezulu kakhulu, ingamelana kalula nokucindezela.

Ngaphezu kwalokho,khetha ama-valvengohlelo oluqinile lokuvimbela ukugeleza emuva, ikakhulukazi uma lusetshenziswa emazingeni okushisa aphezulu.

isiphetho

Kunezinhlobo eziningi zamavalvu emakethe, anezinketho ezihlukene ngaphansi kwezimo ezihlukene zokushisa. Kufanele uchaze izidingo zakho kanye nebanga lokushisa levalvu ezosetshenziswa. Bese ukhetha i-valve ehlangabezana nezindinganiso nemibandela futhi ehlangabezana nazo zonke izidingo zakho. Amaphuzu namathiphu alandelayo kufanele kucatshangelwe ngaphambi kokukhetha ama-valve ngaphansi kwezimo ezihlukene zokushisa.
