Kutshanje, umzi-mveliso wethu ufumene imfuno yemveliso ye-fan-shapeiivalvu zegoggle. Emva kwemveliso enzulu, saqala ukuvavanya le bhetshi yeevalvu ezingaboniyo ukujonga ukuba ngaba kukho ukuvuza ekutywineni umzimba wevalvu kunye nevalve, siqinisekisa ukuba fan nganye-ivalve eyimfama eyimfamaidibana nemigangatho egqwesileyo yemveliso. Sikwaneliseke kakhulu ngeziphumo zovavanyo, kwaye zonke iivalvu ziluphumelele uvavanyo.

Ivalve eyimfama eyimfama sisixhobo sokulawula ulwelo oluxhaphakileyo, esisetyenziswa ikakhulu kulawulo lolwelo kunye nokuvalwa kwiinkqubo zemibhobho. Umgaqo wayo wokusebenza usekelwe kwintshukumo ejikelezayo yemfama, elawula ukuhamba kwamanzi kwipayipi ngokulungelelanisa i-angle yemfama. Uyilo lolwakhiwo lweivelufa eyimfama eyimfamaiyodwa, kunye nemfama ekwimo emile njengefeni kunye ne-angle yokujikeleza ehlengahlengiswayo, ngaloo ndlela ifezekisa ulawulo oluchanekileyo lokuhamba kolwelo.

Xa kuthelekiswa neevalvu zemveli, iivalve eziyimfama eziyimfama zineengenelo ezininzi. Okokuqala, ivalve eyimfama eyimfama inokuchaneka okuphezulu kokulawula ulwelo, uhlengahlengiso oluguquguqukayo, kwaye inokulungelelaniswa ngokucokisekileyo ngokweemfuno zangempela zokuqinisekisa ukusebenza okuzinzile kwenkqubo yombhobho; Okwesibini, ukufakela kunye nokugcinwa kukulungele, ukusebenza kulula, kwaye kulula ukufezekisa ulawulo oluzenzekelayo, oluphucula ukusebenza kakuhle; Ngaphaya koko, ukusebenza kokutywinwa kwevalve yegesi eyimfama emile okwefeni kugqwesile, enokuthintela ngempumelelo iingxaki zokuvuza kunye nokuqinisekisa ukusebenza ngokukhuselekileyo kwenkqubo yombhobho.

Iivalvu eziyimfama eziyimfama zilungele amasimi amaninzi kunye neemeko zoshishino. Okokuqala, kumashishini afana neekhemikhali, i-petroleum, kunye namayeza, iivalvu ezingaboniyo ezimile njengefan zihlala zisetyenziselwa ukulawula ngokucokisekileyo ukuhamba kweendaba, ukuqinisekisa inkqubela phambili egudileyo yenkqubo yokuvelisa; Okwesibini, kwiinkqubo zogutyulo lwelindle kunye nonikezelo lwamanzi, iivalvu ezibubume obufana nefan zokuthengisa abathengi nazo zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza okuqhelekileyo kweenkqubo zemibhobho; Ukongeza, iivalvu eziyimfama ezimile njengefan zisetyenziswa ngokubanzi kwiinkalo ezahlukeneyo zobunjineli njengamashishini anamandla kunye nesinyithi, ukubonelela ngezisombululo ezithembekileyo zokulawula ulwelo lwemveliso kunye nokusebenza.

Isishwankathelo, iivalve zepleyiti eziyimfama ezimile njengefan zidlala indima ebalulekileyo kwimveliso yeshishini ngenxa yolawulo lwazo oluchanekileyo lolwelo, ukusebenza kokutywinwa okugqwesileyo, kunye noluhlu olubanzi lwezicelo. Kwixesha elizayo, ngenkqubela phambili eqhubekayo yetekhnoloji kunye nokwandiswa kweendawo zosetyenziso, sikholelwa ukuba iivalvu ezingaboniyo ezimile okwefeni ziya kudlala indima ebalulekileyo kwaye zibe negalelo kuphuhliso lwamashishini ahlukeneyo.

Ukuba unayo nayiphi na imibuzo okanye iimfuno zoku-odola, nceda uqhagamshelane nathi ngezantsi kwaye uya kufumana isicwangciso sokuthenga esifanelekileyo kwiiyure ze-24. Sijonge phambili ekusebenzeni nawe!
