Kwimbali yokuntywila kwi-scuba diving, iivalvu zetanki zidlale indima ebalulekileyo ekuqinisekiseni ukhuseleko lwabantli-mbini kunye nokuququzelela ukuhlola ngaphantsi kwamanzi. Phakathi kwezona zivalo zaziwa kakhulu yi-valve ye-K kunye ne-J valve. Nantsi intshayelelo emfutshane yezi ziqwenga zinomdla zezixhobo zokuntywila kunye nokubaluleka kwazo ngokwembali.
Ivalve ye-K
Ivalve ye-K sisivalo esilula sokuvula/ukuvala esifumaneka kwiitanki ezininzi zale mihla. Ilawula ukuhamba komoya ngokujika iqhosha ukulawula ukuhamba komoya. Kwidiving diving, ivalve yokuqala ye-K, eyaziwa ngokuba "yintsika ivelufa," ineqhosha eliveziweyo kunye nesiqu esiethe-ethe. Ezi zivalo zakuqala zazinzima ukuzigcina kuba zazisebenzisa imisonto ecolekileyo kwaye zifuna iteyiphu yeTeflon yokutywinwa.
Ngokuhamba kwexesha, uphuculo lwenziwa ukwenza iivalvu ze-K zomelele ngakumbi kwaye kube lula ukuzisebenzisa. Iivalvu zangoku ze-K zibonisa iidiski zokhuseleko, amaqhina aqinileyo, kunye ne-O-ring yetywina eyenza kube lula ukuyifaka nokususa. Ngaphandle kokuhambela phambili kwezixhobo kunye noyilo, umsebenzi osisiseko wevalve ye-K uhlala ungatshintshi.
Iimpawu eziphambili ze-K Valves
●Vula/Vala ukusebenza: Ilawula ukuhamba komoya ngeqhosha elilula.
●Uyilo olomeleleyo: Iivalvu zangoku ze-K zakhiwe ngamaqhina awomeleleyo kunye noyilo lweprofayili ephantsi.
●Iidiski zoKhuseleko: Qinisekisa ukhuseleko kwimeko yoxinzelelo olugqithisileyo.
●ULondolozo olulula: Iivalve zanamhlanje zilula ukufaka kunye nokususa umbulelo kwii-O-ring seals.
Ivalve yeJ
Ivalve engu-J, ngoku ephelelwe lixesha, yayisisixhobo soguqulo lokhuseleko kwiindidi zakudala. Ibonise i-lever yokugcina ebonelela nge-PSI eyongezelelweyo ye-300 yomoya xa abahlukeneyo baqala ukuhla. Le ndlela yogcino yayibalulekile kwixesha langaphambi kweegeyiji zoxinzelelo olungaphantsi kwamanzi, njengoko yayivumela abantu abahlukeneyo ukuba bazi xa bephelelwa ngumoya kwaye kufuneka benyuke.
Iivalvu zakwa-J zangaphambili zazilayishwe entwasahlobo, kwaye i-diver yayiza kuflip i-lever phantsi ukuze ifikelele kwi-air reserve. Nangona kunjalo, i-lever yayityekele ekusebenzeni ngengozi, nto leyo ngamanye amaxesha ishiya abatshuzi ngaphandle kokugcinwa kwabo xa beyifuna kakhulu.
Iimpawu eziphambili zeJ Valves
●I-Reserve Lever: Kubonelelwe nge-PSI eyongezelelweyo engama-300 yomoya xa kuyimfuneko.
●Uphawu loKhuseleko olubalulekileyo: Yenza ukuba abohlukileyo babone umoya ophantsi kunye nomphezulu ngokukhuselekileyo.
●Ukuphelelwa lixesha: Yenziwe ngokungeyomfuneko ngokufika kweegeji zoxinzelelo olungaphantsi kwamanzi.
●Isiqhoboshelo se-J-Rod: Isithinteli sokugcina besisoloko sandiswa kusetyenziswa i-"J-Rod" ukuze kube lula ukufikelela kuyo.
I-Evolution yeScuba Diving Valves
Ngokungeniswa kweegeyiji zoxinzelelo olungaphantsi kwamanzi ekuqaleni kweminyaka yoo-1960, iivalvu ze-J ziye zangafuneki njengoko abantu abahlukeneyo banokubeka iliso kunikezelo lomoya ngokuthe ngqo. Olu phuhliso lukhokelele ekubekweni emgangathweni koyilo lwevalve ye-K olula, oluhlala lulolona hlobo luqhelekileyo lwevalvu esetyenziswayo namhlanje.
Ngaphandle kokuphelelwa lixesha, iivalve ze-J zadlala indima ebalulekileyo kwimbali ye-scuba diving kwaye ziqinisekisa ukhuseleko lwabaninzi abahlukahlukeneyo. Ngeli xesha, iivalvu ze-K ziye zavela ngezixhobo eziphuculweyo kunye noyilo, ziqinisekisa ukhuseleko kunye nokuthembeka kokuntywila kwangoku.
Ukuqukumbela, ukuqonda imbali yeevalvu ze-K kunye ne-J kunika ingqiqo ebalulekileyo malunga nendlela izixhobo zokuntywila eziye zavela ngayo ukuze kuqinisekiswe ukhuseleko lwe-diver kunye nokuphucula amava angaphantsi kwamanzi. Namhlanje, ukuqhubela phambili kweteknoloji kunye nezixhobo ziye zasivumela ukuba siphonononge ihlabathi elingaphantsi kwamanzi ngokuzithemba nangokulula, enkosi ngokuyinxenye kwizinto ezintsha eziveliswayo.
