Ingabe ubhontshisi wekhofi ogazingiwe ungaphekwa ngokushesha?Yebo, kodwa hhayi ngempela esihlwabusayo.Ubhontshisi wekhofi osanda kugazingwa uzoba nesikhathi sokukhulisa ubhontshisi, okuwukukhulula isikhutha futhi kuzuzwe isikhathi esingcono kakhulu sokunambitheka kwekhofi.Ngakho siligcina kanjani ikhofi?Ukugcina ubhontshisi wekhofi, sicabanga ukusebenzisaizikhwama zekhofingokokuqala ngqa, kodwa ingabe uye waqaphela ngokucophelela izikhwama zokupakisha zikabhontshisi wekhofi?Wake wayibona i-valve emhlophe noma ecacile ngemuva noma ngaphakathi kwesikhwama sekhofi?Noma ubonile wanganaki?Ungacabangi ukuthi le valve iyakhishwa uma ubona ukuthi i-valve incane.Eqinisweni, i-valve encane yokushaya iyimfihlo "yempilo noma ukufa" kwamabhontshisi wekhofi.
Le valve iyilokho esikubiza ngokuthi “ivalvu yokukhipha ikhofi”, futhi ibizwa nge-exhaust valve yendlela eyodwa.I-valve yendlela eyodwa idlala indima ebalulekile ekusizeni ikhofi lakho elisha ukuthi lihlale lilisha isikhathi eside.I-valve yendlela eyodwa ngaphakathi kwesikhwama sikabhontshisi wekhofi iyisesekeli sesikhwama esivimbela ukugeleza komoya obuyayo.Ukubuka kafushane kwe-valve ye-exhaust valve yendlela eyodwa kunemisebenzi emibili, owodwa uwukukhipha igesi esikhwameni, kanti omunye uwukuhlukanisa umoya ongaphandle kwesikhwama sokupakisha ukuze ungangeni.Okulandelayo, i-valve yokuthatha i-Wo izokwethula le misebenzi emibili nokuthi isebenza kanjani.
1. Ukukhathala
Ubhontshisi wekhofi oluhlaza uqukethe ama-asidi, amaprotheni, ama-ester, ama-carbohydrates, amanzi kanye ne-caffeine.Ngemva kokuba ubhontshisi bekhofi obuluhlaza bosiwe ezingeni lokushisa eliphezulu, i-carbon dioxide ikhiqizwa ngochungechunge lokusabela kwamakhemikhali njenge-Maillard reaction.Ngokuvamile, i-carbon dioxide namanye amagesi aguquguqukayo akhishwa ubhontshisi wekhofi ogazingiwe enza u-2% wesisindo sawo wonke ubhontshisi wekhofi.Futhi i-2% yegesi ikhishwa kancane kancane esakhiweni se-fiber kabhontshisi, futhi isikhathi sokukhululwa sizoxhomeka endleleni yokugcoba.Ngenxa yokuthi ubhontshisi wekhofi ukhipha isikhutha wodwa, sizobona ubhontshisi wekhofi ogazingiwe esikhwameni esivaliwe esizoqhuma ngokuhamba kwesikhathi.Lokhu okubizwa ngokuthi "isikhwama esivuthwe".Nge-valve yokukhipha indlela eyodwa, kuzosiza ukususa la magesi angenayo esikhwameni ngesikhathi, ukuze lawa magesi angafaki i-oxidize ubhontshisi wekhofi futhi agcine isimo esihle esisha sobhontshisi wekhofi.
2, hlukanisa umoya
Ungawuhlukanisa kanjani umoya ngenkathi uwuqeda amandla?I-valve yendlela eyodwa ihlukile kune-valve yomoya evamile.Uma kusetshenziswa i-valve yomoya evamile, kuyilapho igesi esesikhwameni sokupakisha ikhishwa, izophinde ivumele umoya ongaphandle kwebhande lokupakisha ukuba ugelezele esikhwameni, okuzobhubhisa ukuvalwa kwesikhwama sokupakisha futhi kubangele ukuba ikhofi liqhubeke oxidize.I-oxidation kabhontshisi wekhofi izobangela ukuguquguquka kwephunga kanye nokuwohloka kokwakheka.I-valve yendlela eyodwa yokukhipha ayifuni, iqeda i-carbon dioxide esikhwameni ngesikhathi, futhi ayivumeli umoya ongaphandle ukuba ungene esikhwameni.Ngakho-ke, ikwazi kanjani ukungavumeli umoya wangaphandle ukuba ungene ebhande?I-valve yokukhipha i-Wo ikutshela umgomo wayo wokusebenza: lapho umfutho womoya esikhwameni ufinyelela embundwini othile, ivalvu ye-valve yokukhipha umoya yendlela eyodwa iyavuleka ukuze ikhulule igesi esikhwameni;kuze kube yilapho umfutho womoya wehla ngaphansi kombundu we-valve yendlela eyodwa.I-valve ye-valve yendlela eyodwa ivaliwe, futhi isikhwama sokupakisha sibuyela esimweni esivaliwe.
Ngakho-ke, siphethe ngokuthi i-unidirectionality ye-valve yokukhipha ikhofi iyisidingo sayo esiyisisekelo futhi iyisidingo esiphezulu kakhulu.Lapho ubhontshisi wekhofi osiwe ujule ngokwengeziwe, umphumela wokuqeda uzoba namandla, futhi isikhutha sizokhishwa ngokushesha.
