Sonke siyazi ukubaluleka kwethayi emotweni, kodwa ngethayi, bewazi ukuthi ithayi elincaneivalvu yethayifuthi idlala indima ebalulekile?
Umsebenzi wevalvu ukufutha nokudiliza ingxenye encane yethayi nokugcina isivalo ngemuva kokuba ithayi lifuthwe. Ivalvu evamile yakhiwe izingxenye ezintathu eziyinhloko: umzimba wevalvu, umongo wevalvu kanye nesivalo sevalvu. Lapha ngezansi kuzokunikeza isingeniso esiningiliziwe sevalvu yethayi yemoto.
1. Ihlukaniswe ngenhloso: ivalvu yebhayisikili, isithuthuthu, ivalvu yemoto kagesi, ivalvu yemoto, ivalvu yebhasi yeloli, ivalvu yemoto yobunjiniyela bezolimo, ivalvu ekhethekile, njll.
2. Ngokuya ngokuthi ikhona yini ithubhu noma cha: ithubhu yevalvu ye-tube kanye ne-valvu engenama-tube engenama-tube.
3. Ngokwendlela yokuhlanganisa: i-valve yendawo yonke efakwe ngesikulufo,Ivalvu yokufaka i-clampfuthiivalvu yokungena ngokungena.
4. Ngokuya ngobukhulu bomgodi oyinhloko: ivalvu evamile yegumbi eliyinhloko kanye nevalvu enkulu yegumbi eliyinhloko.
Umzimba wevalvu (isisekelo) uwukuphela kwendlela igesi engena ngayo ethayini, futhi ngesikhathi esifanayo igcina futhi ivikele umongo wevalvu; inathi yokubopha yaziwa ngegama futhi umsebenzi wayo ukwenza ivalvu kanye nomphetho uzinze kakhudlwana; ama-gasket ezinto ezahlukene ahambisana nenathi yokubopha; i-gasket yokuvala irabha idlala indima yokuvala nokuvimbela ukuvuza komoya ohlangothini lwangaphakathi lomphetho; isivalo sevalvu esivame ukulahleka singavimbela ukuhlasela kwevalvu yizinto zakwamanye amazwe, futhi ngesikhathi esifanayo Ukufeza ukuvalwa kwesibili kwevalvu; kanti umongo wevalvu unomsebenzi wokuvimbela igesi ekuvuzeni ngenkathi kuqinisekiswa ukufakwa kwegesi ethayini ngokushelela.
Izindlela zokuhlanganisa ama-valve zingahlukaniswa ngohlobo lwe-screw-on, uhlobo lokucindezela kanye nohlobo lwe-snap-on. Isibonelo, ukuhlanganiswa kwe-valve yerabha kuwuhlobo lwe-snap-in, futhi isisekelo se-valve sinikezwa isikhala sekhadi sokulungisa nge-rim, okuholela ekusetshenzisweni kanye kuphela, futhi uma isisusiwe, ayikwazi ukusetshenziswa futhi. I-valve yensimbi isebenzisa ukuhlanganiswa kwe-screw-on, okusebenzisa ama-gaskets nama-fastening nuts ukulungisa i-valve, futhi ingasetshenziswa kabusha ngemva kokuyiqaqa.
