Kwihlabathi le-fluid dynamics kunye neenkqubo zemibhobho, iivalvu zokutshekisha zidlala indima ebalulekileyo ekuqinisekiseni ukuhamba kakuhle nokukhuselekileyo kolwelo neegesi. Njengenxalenye ebalulekileyo kwiintlobo ezahlukeneyo zezicelo zoshishino, ukuqonda ukuba yintoni i-valve yokutshekisha, iintlobo zayo kunye nabavelisi banokunceda iinjineli kunye neengcali zokuthengwa kwempahla ukwenza izigqibo ezinolwazi. Eli nqaku liza kuphonononga ubunzima beevalvu zetshekhi, lijolise kwiintlobo zayo, imisebenzi kunye nabavelisi abahamba phambili be-valve, ngakumbi e-China.
Ukuqonda Hlola iiValves
Ivalve yokukhangela, eyaziwa ngokuba yi-valve yendlela enye, sisixhobo esivumela ulwelo ukuba luhambe kwicala elinye ngelixa luthintela umva. Oku kubalulekile kwizicelo ezininzi, ezifana neenkqubo zokubonelela ngamanzi, ukucocwa kogutyulo, kunye neenkqubo ezahlukeneyo zamashishini. Umsebenzi oyintloko we-valve yokutshekisha kukukhusela izixhobo kunye nokugcina ingqibelelo yenkqubo ngokuthintela ukubuyisela umva, okunokubangela ukungcola, umonakalo wesixhobo, okanye ukungaphumeleli kwenkqubo.
UmGaqo wokuSebenza weValve yokuHlola
Umgaqo wokusebenza wevalve yokutshekisha kukusebenzisa umahluko woxinzelelo phakathi komlambo onyukayo nasezantsi. Xa uxinzelelo kwicala lokungena ludlula uxinzelelo kwicala lokuphuma, i-valve iya kuvula kwaye ivumele ulwelo ukuba luhambe. Ngokwahlukileyo, ukuba uxinzelelo kwicala lokuphuma luba lukhulu, i-valve iya kuvala kwaye ithintele ukubuyela umva. Le ndlela ilula kodwa esebenzayo yenza ukuba ivalve yokukhangela ibaluleke kakhulu kwiinkqubo ezininzi.
Iindidi zokuHlola iiVavu
Kukho iintlobo ezininzi zeevalve zokukhangela, nganye yenzelwe izicelo ezithile kunye neemeko zokuhamba. Ezona ndidi zixhaphakileyo ziquka:
