Okwangoku, kukho iindidi ngeendidi zeevalvu zebhola kunye neevalvu zeglowubhu kwimarike yezicelo ezahlukeneyo zokusingqongileyo, ke sivavanya njani kwaye singqina ukukhethwa kwevalve yebhola echanekileyo ukufikelela esona siphumo sosetyenziso?Kwinqaku elilandelayo, uRonnie Shidun uxoxa ngeengenelo zeevalvu zebhola kunye neevalvu zeglowubhu kunye nomntu wonke.
1. Umahluko omkhulu phakathi kweevalve ezimbini
Njengoko sonke sisazi, umahluko omkhulu phakathi kwevalve yeglowubhu kunye nevalve yebhola yindlela yokuvala.Iivalvu zeglowubhu zidla ngokusetyenziselwa ukungqusha, kodwa iivalve zebhola zisebenzisa ibhola ukuvala ukuhamba.I-valve yokumisa ilungele ukulungelelanisa ukuhamba, ngelixa i-valve yebhola inomsebenzi ogqwesileyo kwaye inokulawula ukuhamba ngaphandle koxinzelelo.
Ivalve yebhola inesiqu kunye nebhola ejikeleza ngokuthe tye, kwaye isoloko ibizwa ngokuba yivalve “ejikelezayo”.Nangona kunjalo, ivalve yeglowubhu inesikhondo sevalvu kunye nombindi wevalvu, kwaye isiqu sevalve kunye nombindi wevalvu zithatha istroke emgca, kwaye ivalve yokumisa apho ikhoyo ikwabizwa ngokuba yivalve “yestroke”.
2. Iimpawu ezisisiseko zeevalvu ezimbini
Ivalve yebhola:
1) Ukuvalwa kwamanzi kwi-valve yebhola kuncinci, kwaye isandi sokusebenza siphantsi;
2) Olu hlobo lwesivalo lunesakhiwo esilula, ukufakwa okungenamkhawulo, ubungakanani obuncinci, ubunzima bokukhanya, kunye neemfuno zokugcinwa okuphantsi.
3) Indawo ephakathi kwevalve yebhola iyahlukana kwaye ihambe ngaphandle kokungcangcazela;
4) Ukuchaneka kokulungiswa kwevalve yebhola kuphezulu, kwaye ixabiso liphezulu;
5), awukwazi ukugoba.
Ivalve yokuvala:
1).Olu hlobo lwevalve lunesakhiwo esilula kunye neemfuno eziphantsi zokucwangcisa kunye nokugcinwa.
2) I-valve yokuvala inokuvulwa kwaye ivalwe ngexesha elifutshane phantsi kokusebenza kwexesha elifutshane;
3) Ukusebenza kokutywinwa kulungile, ukungqubuzana kwindawo yokutywina kuncinci, kwaye kunokusetyenziswa ixesha elide.
4) Ukukhutshwa kwamanzi oluhlobo lwevalve kukhulu kakhulu, kwaye amandla amakhulu aya kuveliswa ngexesha lokuvula nokuvalwa kwenkqubo.
5) I-valve yokumisa ayifanelekanga ukulawula ulwelo kunye neengqungquthela ze-viscous.
3. Ulwenza njani ukhetho olungcono phakathi kwevalve yebhola kunye nevalve yeglowubhu?
Ivalve yebhola yomelele kwaye isebenze kakuhle emva kwemijikelo emininzi;ithembekile kwaye inokuvalwa ngokukhuselekileyo nokuba ixhatshazwe ixesha elide.Xa kuthelekiswa neevalvu zesango kunye neglobhu, ezi mpawu zinceda iivalve zebhola zibe lukhetho olubalulekileyo kwizicelo zokuvala.Kwelinye icala, iivalvu zebhola ziswele ulawulo olululo kwi-throttling applications olubonelelwa ziivalvu zeglowubhu.
