Emkhiqizweni wesimanje, ama-valve, njengamathuluzi abalulekile okulawula uketshezi, adlala indima ebalulekile. Ukuthiizivalo uvemvane, ama-valve esango, nomahlola ama-valve, badlala indima ebalulekile ezimbonini ezihlukahlukene. Ukuklanywa nokukhiqizwa kwalawa ma-valve kuhlanganisa ubuciko obuhle nokuthuthuka kwezobuchwepheshe. Ngemuva kwakho konke lokhu, othisha embonini yama-valve bawumgogodla wefa kanye nokusungula izinto ezintsha. Abagcini nje ngokusabalalisa ulwazi, kodwa futhi bangabagadi bomsebenzi wezandla.
Amavalvu ebhabhathane, ezaziwayo ngomklamo wazo ongasindi, umthamo wokugeleza okuphezulu, nokusebenza okuhle kakhulu kokuvala, zisetshenziswa kakhulu ezimbonini ezifana ne-petroleum, ubunjiniyela bamakhemikhali, namandla kagesi. Ukuklama nokukhiqiza kwabo kudinga isisekelo esiqinile kwezobuchwepheshe kanye nolwazi olunzulu olusebenzayo. Abafundisi bemboni yamavalvu badlulisela lolu lwazi kubafundi ngokusebenzisa iziyalezo ezihlelekile, ukuhlakulela izizukulwane ezilandelanayo zethalente lobuchwepheshe elivelele. Abagcini nje ngokufundisa abafundi indlela yokuklama nokwenza ama-valve ovemvane, kodwa okubaluleke nakakhulu, babafundisa indlela yokuqonda amathiyori ayisisekelo njengomshini we-fluid mechanics kanye nesayensi yezinto, okubenza bakwazi ukuwasebenzisa ngokuguquguqukayo ezimweni zomhlaba wangempela.
Ama-valve esangoama-valve avamile, asetshenziswa kakhulu ukuvala noma ukuxhuma uketshezi emapayipini. Nakuba kulula ngesakhiwo futhi kulula ukusebenza, ukukhiqiza kwawo kudinga ukukhethwa kwezinto eziphezulu kakhulu kanye nokunemba. Iminikelo yothisha bemboni yama-valve kulo mkhakha ayinakubukelwa phansi. Ngokufundisa ngezandla, avumela abafundi ukuthi bahlanganyele mathupha enqubweni yokukhiqiza ama-valve esango, beqonda ukubaluleka kwesinyathelo ngasinye. Lokhu kuqoqwa kolwazi olusebenzayo akugcini nje ngokuthuthukisa amakhono abafundi asebenzayo kodwa futhi kubeka isisekelo esiqinile semisebenzi yabo yesikhathi esizayo.
Hlola ama-valvezingamathuluzi abalulekile okuvimbela uketsheziukubuyela emuva futhi asetshenziswa kakhulu ekuhlanzeni amanzi, ekushiseni nasekunikezeni igesi. Ukuklanywa nokukhiqizwa kwama-valve okuhlola kubandakanya ulwazi oluvela emikhakheni eminingi, okuhlanganisa nokuguquguquka koketshezi kanye nokwakheka kwemishini. Ngokusebenzisa iziyalezo ezihlukene, abafundisi embonini yamavalvu basiza abafundi ukuba bakhe isisekelo solwazi esibanzi, esibenza bakwazi ukubhekana nezinselele zobuchwepheshe eziyinkimbinkimbi zemisebenzi yabo yesikhathi esizayo.
Embonini ye-valve, othisha abagcini nje kuphelaiyanikeza ngolwazi kodwa futhi nabazuzi bobungcweti. Basebenzisa ulwazi lwabo kanye nokuhlakanipha kwabo ukuthuthukisa izizukulwane zamakhono okukhiqiza ama-valve, okunegalelo ekuthuthukisweni kwemboni yokukhiqiza yaseShayina. Kungenxa yomsebenzi onzima walaba thisha ukuthi imboni yama-valve ingaqhubeka nokuqamba izinto ezintsha nokuqhuba intuthuko kuyo yonke imboni yokukhiqiza.
Emhlabeni wanamuhla womhlaba wonke, imboni yezokukhiqiza ibhekene nezinselele namathuba angakaze abonwe. Njengengxenye ebalulekile yemboni yokukhiqiza, imboni yamavalvu kufanele iqhubeke ithuthukisa amakhono ayo ezobuchwepheshe kanye nekhono lokusungula izinto ezintsha. Le mpumelelo ayinakuhlukaniswa nokusebenza kanzima nokuzinikela kothisha bethu. Kufanele sibathulele isigqoko laba abazuza ifa lalo msebenzi futhi sibabonge ngegalelo labo embonini yama-valve kanye nomhlaba wonke wokukhiqiza.
Ngamafuphi, ukwenziwa kweizivalo uvemvane, ama-valve esango, futhihlola ama-valveayidingi nje kuphela ubuchwepheshe obuphambili kodwa nezingcweti ezisezingeni eliphezulu. Othisha embonini yama-valve bawumthombo wala mandla, futhi imizamo nokuzinikela kwabo kuzoqhubeka nokukhuthaza ukuthuthukiswa okunamandla kwemboni yezokukhiqiza yezwe lami.
