Amavalvu ebholafuthiamavalvu ebhabhathane ziyizigaba ezimbili ezibalulekile zamavalvu futhi zisetshenziswa kabanzi. Ivalvu yebhola idinga ukuvalwa okuqinile ekushiseni okuphezulu kanye nokucindezela okuphezulu kanye nokumelana nokugeleza okuphansi. Amavalvu e-Butterfly asetshenziswa kakhulu ezimweni zokusebenza ezinezimfuneko zokucindezela okuphansi kanye nokuvala okuphansi.

 

Kukhona futhi ukuhlukaniswa okuningi kwama-valve ebhola nama-valve e-butterfly. Ama-valve ebhola angahlukaniswa kanje: ama-valve ebhola aqinile ensimbi, ama-valve ebhola athambile, ama-valve ebhola antantayo, ama-valve ebhola aqinile, ama-valve e-semi-ball angavamile, ama-valve ebhola alawulayo anomumo we-V, njll.

 

Ivalvu yebhabhathane ihlukaniswe phakathi: ivalvu yebhabhathane emithathu engavamile, ivalvu yebhabhathane ephindwe kabili engavamile, ivalvu yebhabhathane ephakathi nendawo, ivalvu yebhabhathane eqinile, ivalvu yebhabhathane ethambile evalayo.

 

Ama-valve ebhola nama-valve e-butterfly yi-valve evame ukusetshenziswa. Kwezinye izimo, womabili angasetshenziswa ngokusetshenziswa okuvamile, futhi kwezinye izimo zokusebenza, elilodwa kuphela lawo lingasetshenziswa. Izici ezifanele zalezi zinhlobo ezimbili zama-valve. Sihlaziya kafushane:

I-valve yebhola: i-valve ye-cock yavela, ingxenye yokuvula neyokuvala iyindilinga, izici yilezi:

1. Ukumelana nokujikeleza kwegazi kuncane. Uma kuvulwe ngokuphelele, azikho izingxenye ezivimba ukuhamba kwe-medium esiteshini;

2. Ingavalwa ngokuphelele ngaphansi kwengcindezi ephezulu kanye nokushisa okuphezulu;

3. Ingavulwa futhi ivalwe ngokushesha;

4. Qaphela ukumelana nokuguguleka okuphezulu kanye nokumelana nokugqwala okunamandla ngokwelashwa kokuqina;

5. Umzimba wevalvu ulingana, ongakwazi ukumelana ngempumelelo nomfutho wepayipi futhi ungabhekana nezimo zokusebenza ezinomfutho ophezulu.

 

I-valve ye-Butterfly: Ingxenye yokuvula nokuvala iyipuleti ye-butterfly yohlobo lwediski, ebonakala ngalokhu:

1. Isakhiwo esilula, usayizi omncane kanye nokufakwa okulula;

2. I-coefficient encane yokumelana nokugeleza, ukuvulwa nokuvalwa okusheshayo;

3. Ingasetshenziswa kuma-valve amakhulu;

4. Izindawo zokuvala ezihlukene zingasetshenziswa ezindaweni ezahlukene, kufaka phakathi imidiya eyimpuphu kanye ne-granular.

 

Uma kuqhathaniswa ne-valve yebhola, i-valve yebhabhathane inokusebenza kokuvala okubi kancane, kodwa phakathi kwama-valve amakhulu, i-valve yebhabhathane inenzuzo eyingqayizivele kune-valve yebhola; uma isetshenziswa ukulungisa izinga lokugeleza, i-valve yebhabhathane inobubanzi obuncane bokulungisa, kuyilapho i-valve yebhola yokulungisa yohlobo lwe-V ilungiseka. Emapayipini anomfutho ophezulu, ama-valve ebhola anezinzuzo ngaphezu kwama-valve ebhabhathane.
