I-Valve iphendulela ukuphuma kwe-ventilation: ukubukeka kanye nobubanzi

I-valve eguquguqukayo ye- ventilation ihloswe ekuqedeni ukuhamba kwe-air inverse ezindaweni zokungenisa umoya , uma i-fan ivuliwe. Uma uhlelo lwentambo yokuvuthwa luvaliwe, akunakwenzeka ukuvumela ukuhamba emoyeni obandayo ngaphandle komgwaqo we-hood, ngaphezu kwalokho, kwenza kube lula ukuvikela umoya wokungena emanzini, uthuli nezinye izinto.

I-valve eguquguqukayo ye-ventilation ingafakwa ngokuqondile noma ngokuzungezile, kuye ngokuthi yimiphi imisebenzi ngaphambi kwayo. Uma efakwe endaweni eqondile, kubalulekile ukucabangela ukuthi ukugeleza komoya kufanele kube nesiqondiso kusuka phansi phezulu. Uma ufaka ngokuzungezile, kubalulekile ukuthi izinga lokugeleza lingaphezu kwamamitha ayisithupha ngomzuzwana, futhi ukufakwa okuqondile, okungaphezu kwamamitha amane.

I-valve eguquguqukayo ye-ventilation inesimo se-blade ihlelwe phezu kwemigodi futhi ifakwe ezindlini. Ukuqhathaniswa kwe-cylindrical kufakwe ku-axis, okuvumela ukubamba iqhwa endaweni evaliwe lapho umshayeli evuliwe, okuvumela ukuvula ngokusemandleni lapho ukugeleza komoya kuqala ukuhamba. Amaplangeni okuxhuma ama-valve anikezwa ngezimbalo ezijwayelekile ezibekiwe ukuze kube nokubekwa kwawo okuqinile emgodini noma epayipi.

I-valve yokuhlola ye-ventilation, intengo yayo engabizi kakhulu, ingaba yinye yezinhlobo ezimbili: ukuba nesigaba ngendlela yombuthano noma umugqa. Uhlobo oluvame kakhulu nxazonke luhlobo lwe "butterfly". Yakha ukwakhiwa kwesigcawu sezinhlangothi ezimbili, okuhlukanisa i-valve zibe izingxenye ezimbili. I-air ingadlula kuphela endaweni eyodwa, ngoba amacembe aphuma ngokukhethekile kule njongo. Uma ukugeleza kuqondiswa emuva, bese bevala. Kulesi simo, kukhona okunye okuphawulekayo okushiwo: amathuba okushada ngenxa yesithwathwa kwenye yezindawo eziphezulu.

I-valve ye-air check for ventilation ingasetshenziselwa izinhlelo zokukhishwa kwendlu. Ngezinye izikhathi ukukhishwa endlini yokugezela kusuka emafulethini angomakhelwane kugoqa iphunga elimnandi. Kule nkinga, indlela enhle kakhulu yokuphuma kweso simo kungase kube ukufaka ihood nge-valve engavumele ukubuya. Awuvumeli umoya kusuka e-shaft yomoya wokungenisa umoya ukungena ekamelweni uma umshayeli evaliwe. Uma ivuliwe, ukukhishwa kwomoya kuya emayini kuzokhishwa.

Njengesivinini sokuhlola, i-grate engenayo ivame ukusetshenziswa, efakwe kusuka ngaphandle. Idivayisi yayo ihloselwe ekuvuleleni izimpumputhe ngendlela eyodwa kuphela, ngakho-ke uma i-hood ivaliwe, izovalwa. Kubalulekile ukuphawula ukuthi ezinye izimo zokusebenza zingabangela ngisho nokugaya okunamandla ukunamathela. Lesi sici kufanele sicatshangelwe uma kudala umoya wokuphuza umoya. Ngendlela efanele kulolu daba, ungafinyelela umphumela omuhle kakhulu.

Ngakho-ke, i-valve eguquguqukayo ye-ventilation ingenziwa ngendlela yedivaysi evamile yomklamo olula, noma ngesimo se-inertial grating. Ngokuphathelene nohlobo oluthile ludinga izimo ezikhethekile zokufaka idivayisi.
