Emlandweni we-scuba diving, ama-valve ethangi adlale indima ebalulekile ekuqinisekiseni ukuphepha kwabatshuzi kanye nokwenza lula ukuhlola ngaphansi kwamanzi. Phakathi kwama-valve amadala aziwa kakhulu kukhona i-valve ye-K kanye ne-J valve. Nasi isingeniso esifushane salezi zingcezu ezihehayo zemishini yokutshuza kanye nokubaluleka kwazo komlando.
Ivalve ye-K
Ivalve ye-K iyivalvu elula yokuvula/yokuvala etholakala emathangeni amaningi esimanje e-scuba. Ilawula ukugeleza komoya ngokuphendula ifindo ukulawula ukugeleza komoya. Ku-diving yakudala, i-valve ye-K yasekuqaleni, eyaziwa ngokuthi "i-valve yensika," yayinefindo eliveziwe kanye nesiqu esintekenteke. Lawa ma-valve okuqala ayenzima ukuwanakekela ngoba ayesebenzisa izintambo ezicijile futhi adinga itheyiphu ye-Teflon ukuze izovalwa.
Ngokuhamba kwesikhathi, kwenziwa intuthuko ukwenza amavalvu e-K aqine futhi kube lula ukuwasebenzisa. Amavalvu esimanje e-K afaka amadiski okuphepha, amafindo aqinile, kanye ne-O-ring seal ewenza kube lula ukuwafaka nokuwakhipha. Naphezu kokuthuthuka kwezinto zokwakha kanye nokuklama, umsebenzi oyisisekelo we-valve ye-K uhlala ungashintshiwe.
Izici ezibalulekile ze-K Valves
●Vula/Vala Ukusebenza: Ilawula ukugeleza komoya ngeknobho elilula.
●I-Robust Design: Amavalvu esimanje e-K akhiwe ngamafindo aqinile kanye nomklamo osezingeni eliphansi.
●Amadiski okuphepha: Qinisekisa ukuphepha uma kwenzeka ucindezela ngokweqile.
●Ukugcinwa Okulula: Ama-valve esimanje kulula ukuwafaka nokuwakhipha ngenxa yezimpawu ze-O-ring.
I-J Valve
I-valve engu-J, manje engasasebenzi, yayiwumshini wokuphepha oguquguqukayo wabatshuzi besikhathi esidlule. Ifaka i-reserve lever ehlinzeka nge-PSI yomoya engu-300 eyengeziwe lapho abatshuzi beqala ukwehla. Lo mshini wokugodla wawubalulekile enkathini yangaphambi kwezikali zengcindezi engaphansi kwamanzi, njengoba wawuvumela abatshuzi ukuthi bazi lapho bephelelwa umoya futhi kudingeka bakhuphuke.
Ama-valve asekuqaleni ka-J ayelayishwe entwasahlobo, futhi i-diver yayijikisa i-lever phansi ukuze ifinyelele ukunikezwa komoya obekiwe. Kodwa-ke, i-lever yayithambekele ekwenzeni kusebenze ngephutha, okwakushiya abatshuzi ngezinye izikhathi bengenayo indawo yabo lapho beyidinga kakhulu.
Izici Eziyinhloko ze-J Valves
●I-Reserve Lever: Ihlinzekele nge-PSI eyengeziwe engu-300 yomoya lapho kudingeka.
●Isici Esibalulekile Sokuphepha: Inike amandla abatshuzi ukuthi babone umoya ophansi nendawo ngokuphepha.
●Ukuphelelwa yisikhathi: Kwenziwe kungenasidingo ngokufika kwamageji okucindezela angaphansi kwamanzi.
●Okunamathiselwe kwe-J-Rod: I-reserve lever yayivame ukunwetshwa kusetshenziswa i-"J-Rod" ukuze kube lula ukuyifinyelela.
Ukuvela kwe-Scuba Diving Valves
Ngokwethulwa kwezikali zengcindezi engaphansi kwamanzi ekuqaleni kwawo-1960, ama-valve e-J agcina engasadingeki njengoba abatshuzi sebengakwazi ukuqapha ukunikezwa komoya kwabo ngokuqondile. Lokhu kuthuthukiswa kwaholela ekumisweni komklamo olula we-valve we-K, okuhlala kuwuhlobo oluvame kakhulu lwe-valve olusetshenziswa namuhla.
Naphezu kokuphelelwa yisikhathi, ama-valve e-J abambe iqhaza elibalulekile emlandweni we-scuba diving futhi aqinisekisa ukuphepha kwabatshuzi abangenakubalwa. Ngaleso sikhathi, ama-valve e-K athuthukile ngezinto zokwakha ezithuthukisiwe kanye nomklamo, oqinisekisa ukuphepha nokwethembeka ekutshuzeni kwesimanjemanje.
Sengiphetha, ukuqonda umlando wamavalvu e-K kanye no-J kunikeza ukuqonda okubalulekile kokuthi izinto zokusebenza ze-scuba diving ziguquke kanjani ukuze kuqinisekiswe ukuphepha kwe-diver kanye nokuthuthukisa ulwazi lwangaphansi kwamanzi. Namuhla, intuthuko kwezobuchwepheshe nezinto zokwakha isivumele ukuthi sihlole umhlaba ongaphansi kwamanzi ngokuzethemba nangokukhululeka, sibonga ngokwengxenye emisha yala mavalvu aqalayo.
