Yintoni iivalvu zeBhola?
Iivalvu zebhola zivala ukuhamba kwamanzi zisebenzisa ingqukuva encinane, okanye ibhola, ngaphakathi kwevalve. Ingqukuva inomngxuma ngaphakathi. Xa "kwindawo", ukuvulwa kuhambelana nombhobho, okuvumela amanzi ukuba ahambe ngokukhululekile. Xa kwindawo "yokucima", ukuvulwa kuxhomekeke ekuphumeni kwamanzi, ukumisa ukuhamba ngokupheleleyo. Kwivalve yebhola, ukuhamba kulawulwa nge-lever. Ukubeka i-lever perpendicular kumbhobho kuvumela amanzi ukuba ahambe. Ukuyihambisa kwi-engile ye-90-degree kumisa ukuhamba.
Iivalvu zebhola zineenzuzo ezininzi. Zilula ukuzilayita nokucima ngokukhawuleza, kwaye zinokusetyenziswa ngabantu abangakwaziyo ukuqhuba ivalve esebenza ngamavili ngenxa yokukhubazeka. Bavumela umsebenzisi ukuba axele krwaqu ukuba ivalve ivuliwe okanye hayi. Zihlala ixesha elide, azifane zibe ngumkhenkce nangona zineminyaka zisetyenziswa, zibonelela ngenkonzo ethembekileyo, kwaye ziguquguquka kakhulu. Iivalvu zebhola zisetyenziswa kwimibhobho yamanzi yasekhaya, izicelo zoshishino, izicelo zeoyile negesi, izicelo zaselwandle, amayeza, kunye nezinye iinkalo ezininzi.
Ukungalungi okuphambili kwevalve yebhola yimfuneko yendawo. Kwiinkqubo eziqinileyo, awunakuba needigri ezingama-90 ukuguqula isiphatho sevalve. Kwakhona, kwiimeko ezinqabileyo ivalve yebhola inokudala imeko yehamile yamanzi.
