Sonke siyayazi indlela itayara elibaluleke ngayo emotweni, kodwa ngaba ubusazi ukuba itayara elincinciivalvu yetayaraikwadlala indima ebalulekileyo?
Umsebenzi wevalvu kukufutha nokuthomalalisa inxalenye encinci yevili kunye nokugcina itywina emva kokuba ivili livuthelwe. Ivalvu eqhelekileyo yenziwe ngamacandelo amathathu aphambili: umzimba wevalvu, umongo wevalvu kunye nesigqubuthelo sevalvu. Apha ngezantsi siza kukunika intshayelelo eneenkcukacha ngevalvu yevili lemoto.
1. Yahlulwe ngokwenjongo: ivalvu yebhayisekile, isithuthuthu, ivalvu yesithuthi sombane, ivalvu yemoto, ivalvu yebhasi yelori, ivalvu yesithuthi sobunjineli bezolimo, ivalvu ekhethekileyo, njl.njl.
2. Ngokwe-nokuba kukho ityhubhu okanye akunjalo: ityhubhu yevalvu yetyhubhu kunye netyhubhu yevalvu engenatyhubhu.
3. Ngokwendlela yokuhlanganisa: ivalvu yendalo yonke ekwisikrufu,Ivalvu yokufaka i-clamp-inkwayeivalvu yokungena ngaphakathi.
4. Ngokwesayizi yomgodi ongundoqo: ivalvu yegumbi eliqhelekileyo elingundoqo kunye nevalvu yegumbi elikhulu elingundoqo.
Umzimba wevalvu (isiseko) yindlela ekuphela kwayo yokuba igesi ingene kwitayara, kwaye kwangaxeshanye igcina kwaye ikhusele umongo wevalvu; inathi yokuncamathisela yaziwa ngegama kwaye umsebenzi wayo kukwenza ivalvu kunye nomphetho uzinze ngakumbi; ezimbini Iigaskets zezinto ezahlukeneyo zihambelana nenathi yokuncamathisela; i-gasket yokutywina irabha idlala indima yokutywina nokuthintela ukuvuza komoya kwicala langaphakathi lomphetho; isivalo sevalvu esihlala silahleka sinokuthintela ukuhlaselwa kwevalvu zizinto zangaphandle, kwaye kwangaxeshanye Ukufezekisa ukutywinwa kwesibini kwevalvu; kwaye umongo wevalvu unomsebenzi wokuthintela igesi ekuvuzeni ngelixa kuqinisekiswa ukufakwa kwegesi kwitayara ngokutyibilikayo.
Iindlela zokuhlanganisa iivalvu zinokwahlulwa zibe ziintlobo zeskrubhu, uhlobo lokucinezela kunye nohlobo lwesnap-on. Umzekelo, ukuhlanganiswa kwevalvu yerabha luhlobo lwesnap-in, kwaye isiseko sevalvu sinikwe indawo yekhadi yokulungisa irim, nto leyo ekhokelela ekusetyenzisweni kube kanye, kwaye xa isusiwe, ayinakusetyenziswa kwakhona. Ivalvu yesinyithi isebenzisa indibano yeskrubhu, esebenzisa iigaskets kunye neenati zokubopha ukulungisa ivalvu, kwaye inokusetyenziswa kwakhona emva kokuyiqhaqha.
