Iivalvu zee-angle zixhaphakile emakhayeni ethu, kodwa abantu abaninzi abazi igama lazo. Ngoku makhe sijonge ekuchazeleni abafundi ukuba zeziphi iingenelo zevalvu yee-angle kunezinye iintlobo zeevalvu. Zingasinceda senze ukhetho olungcono xa sikhetha iivalvu.
Ivalvu ye-engile
· Uphawu oluPhambili:Ukungena kunye ne-outlet zenza i-engile yasekunene engama-90 degrees.
· Iingenelo eziphambili:
- Igcina indawo yokufaka: Uyilo lwe-90-degree luvumela uqhagamshelo oluthe ngqo kwiipayipi ze-engile yasekunene, nto leyo esusa isidingo seengqiniba ezongezelelweyo.
- Indlela elula yokuhamba kwamanzi, ikwazi ukuzicoca: Isiphumo esinamandla sokuqubha kwamanzi sinceda ukuthintela ukuvaleka.
· Imeko zokusetyenziswa: Ukuhombisa ikhaya (iipompo/izindlu zangasese ezidibanisayo), iinkqubo zoshishino ezifuna uqhagamshelo lwemibhobho ekwikona yasekunene.
· Imida/Amanqaku:
- Ukusetyenziswa ekhaya: Umsebenzi ulula, ikakhulu kukutshintsha kunye nokunxibelelana.
- Ukusetyenziswa kwimizi-mveliso: Isetyenziswa rhoqo njengendlela yokulawula ivalvu, igxininisa ukusebenza kolawulo.
2. Iivalvu ezisebenzayo ngomgca (ezifana neevalvu zokumisa ezithe tye, iivalvu zesihlalo esinye/ezibini)
· Uphawu oluphambili:I-valve core ihamba inyuka ihla, kwaye i-inlet kunye ne-outlet zihlala zikwi-direct straight.
· Xa kuthelekiswa neentsilelo zeevalvu ze-engile:
- Ukumelana nokuhamba kwamanzi okuphezulu kunye nokuvaleka: Indlela yokuhamba kwamanzi iyinkimbinkimbi (emile njengo-S), kukho iindawo ezininzi ezifileyo, kwaye i-medium ithanda ukufumba.
- Ulwakhiwo olunzima: Umthamo kunye nobunzima bukhulu kakhulu.
- I-valve stem seal isengozini yokonakala: Intshukumo ejikelezayo ye-valve stem iyenza iguge lula ipakeji, nto leyo ebangela ukuvuza.
· Iimeko zokusetyenziswa: Zifanelekile kwimicimbi emincinci eneemfuno eziphezulu zokuchaneka komthetho kunye nemidiya ecocekileyo.
3. Ivalvu yebhola
· Uphawu oluphambili:I-valve core ngumzimba ongqukuva onomngxuma odlulayo, kwaye iyavuleka ize ivale ngokujikeleza ii-degrees ezingama-90.
· Iingenelo xa kuthelekiswa neevalvu ze-engile:
- Ukumelana nolwelo okuphantsi kakhulu: Xa ivuliwe ngokupheleleyo, indlela yokuhamba kwamanzi imalunga nombhobho othe tye.
- Ukuvula nokuvala ngokukhawuleza: Kufuna ukujikeleza ngama-degree angama-90 kuphela.
· Umahluko kwiivalvu ze-engile:
- Ivalvu ye-engile yi-engile yoqhagamshelwano, ngelixa ivalvu yebhola luhlobo lwendlela yokuvula nokuvala. "Ivalvu ye-engile yebhola" idibanisa iingenelo zoqhagamshelwano lwe-90-degree kunye nokuvula nokuvala ngokukhawuleza.
· Iimeko zokusetyenziswa: Zifanelekile kwiipayipi ezifuna ukuvalwa ngokukhawuleza kunye nokulahleka koxinzelelo oluphantsi, kunye nokusetyenziswa okubanzi.
4. Iivalvu zokulawula intshukumo ezithe tyaba (ezifana neevalvu ze-engile, iivalvu zebhabhathane, iivalvu ezijikelezayo ezingaqhelekanga)
· Uphawu oluphambili:I-valve core iyajikeleza (ayihambi phezulu nasezantsi), iyinxalenye yodidi olubanzi.
· Iingenelo ezipheleleyo (xa kuthelekiswa neevalvu ezithe ngqo):
- Ukusebenza kakuhle kakhulu ekuthinteleni ukuvaleka: Indlela ethe tye yokuhamba kwamanzi, zimbalwa iindawo ezifileyo, kwaye azinangxaki yokuvaleka kwamanzi.
- Ulwakhiwo oluncinci nolukhaphukhaphu: Ubunzima bunokwehliswa ngama-40% - 60%.
- Ukutywina okuthembekileyo, ubomi benkonzo ende: Isiqu sevalvu sijikeleza kuphela ngaphandle kokunyuka nokuhla, kwaye ukusebenza kokutywina kulungile.
- I-coefficient enkulu yokuhamba kwamanzi: Umthamo wokuhamba kwamanzi unamandla ngakumbi ngaphantsi kobubanzi obufanayo.
