Ama-valve ebholafuthiizivalo uvemvane yizigaba ezimbili ezibalulekile zama-valve futhi asetshenziswa kabanzi.I-valve yebhola idinga ukubekwa uphawu okuqinile ekushiseni okuphezulu nokucindezela okukhulu nokumelana nokugeleza okuphansi.Ama-valve ovemvane asetshenziswa kakhulu ezimweni zokusebenza ezinomfutho ophansi kanye nezidingo zokuvala eziphansi.

 

Kukhona futhi izigaba eziningi zama-valve ebhola nama-butterfly valves.Ama-valve ebhola angahlukaniswa abe: ama-valve ebhola ensimbi avale ngokuqinile, ama-valve ebhola avaliwe, ama-valve amabhola antantayo, ama-valve amabhola angashintshi, ama-semi-ball eccentric, ama-valve alawulayo amise okwe-V, njll.

 

I-valve uvemvane ihlukaniswe yaba: i-valve uvemvane oluyi-eccentric, i-valve uvemvane ene-eccentric ephindwe kabili, i-centerline butterfly valve, i-valve uvemvane evala kanzima, ivalve uvemvane evala uphawu.

 

Ama-valve ebhola kanye nama-butterfly valves avame ukusetshenziswa.Kwezinye izimo, zombili zingasetshenziswa ekusetshenzisweni okuvamile, futhi kwezinye izimo zokusebenza, eyodwa kuphela yazo ingasetshenziswa.Izici ezifanele zalezi zinhlobo ezimbili zama-valve.Sihlaziya kafushane:

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

1. Ukumelana nokujikeleza kuncane.Lapho ivulwe ngokugcwele, azikho izingxenye ezivimba ukugeleza kwendawo ephakathi esiteshini;

2. Ingavalwa ngokuphelele ngaphansi kwengcindezi ephakeme kanye nokushisa okuphezulu;

3. Ingavulwa futhi ivalwe ngokushesha;

4. Bona ukumelana nokuguga okuphezulu kanye nokumelana nokugqwala okuqinile ngokwelashwa okuqinile;

5. Umzimba we-valve uno-symmetrical, ongakwazi ukumelana ngokuphumelelayo nokucindezela kwepayipi futhi ukwazi ukubhekana nezimo zokusebenza ezinomfutho ophezulu.

 

I-Butterfly valve: Ingxenye yokuvula neyokuvala uhlobo lwe-butterfly plate, olubonakala ngokuthi:

1. Isakhiwo esilula, usayizi omncane kanye nokufakwa okulula;

2. I-coefficient yokumelana nokugeleza okuncane, ukuvula nokuvala ngokushesha;

3. Ingasetshenziselwa ama-valve amakhulu amakhulu;

4. Izindawo ezihlukene zokuvala zingasetshenziswa ezindaweni ezihlukahlukene, kuhlanganise ne-powdery ne-granular media.

 

Uma kuqhathaniswa ne-valve yebhola, i-valve ye-butterfly inomsebenzi wokuvalwa kancane kancane, kodwa phakathi kwama-valve amakhulu, i-valve ye-butterfly inenzuzo eyingqayizivele phezu kwe-valve yebhola;lapho isetshenziselwa ukulungisa izinga lokugeleza, i-valve ye-butterfly inebanga elincane lokulungiswa, kuyilapho i-valve yebhola yokulungiswa kwe-V ilungiswa.Emaphayiphini anengcindezi ephezulu, amavalvu ebhola anezinzuzo ngaphezu kwamavalve uvemvane.
