Ukuphefumula valve

Incazelo emfushane:

Endaweni yokusebenza eshisayo nenomswakama engenawo umoya omncane noma ivolumu enkulu yabasebenzi, ukusetshenziswa kwesifihla-busi se-anti haze nge-valve yokuphefumula kungakusiza uzizwe ukhululekile lapho ukhipha umoya. 


Imininingwane yomkhiqizo

Amathegi womkhiqizo

Umgomo wokusebenza we-valve yokuphefumula yesifihla-buso sokulwa nomoya ukushaya ipuleti le-valve livuleke ngaphansi kwengcindezi enhle yegesi yokukhipha lapho ukhipha, ukuze ususe ngokushesha igesi yokukhipha emzimbeni futhi wehlise umuzwa ogcwele futhi oshisayo lapho usebenzisa imaski yokulwa nenkungu, kuyilapho ingcindezi engemihle izovala i-valve ngokuzenzakalela lapho ihogela, ukuze kugwenywe ukungcola okungene endaweni yangaphandle. Yimaphi ama-majors adumile ama-majors endawo? Kungabonakala ohlwini ukuthi i-anti haze mask ene-valve yokuphefumula ilungele imvelo yokusebenzisa kabi futhi inenzuzo enkulu ekuphefumuleni kwabantu. Isifihla-buso se-anti haze esine-valve yokuphefumula singakhipha ngokushesha umoya oshisayo nomswakama ophuma kumaski. Uma kungekho umshini wokuphefumula one-valve yokuphefumula, umoya oshisayo nonomswakama ozokhishwa kuzofanele uphinde uphume kukotini wokuhlunga futhi. Ngoba umoya wangaphandle uyabanda, umoya oshisayo nonomswakama uzothwelana ungene emaconsi amanzi lapho kubanda, okulula ukumanzisa ukotini wokuhlunga, kubangele ukukhiqizwa kwamagciwane futhi kunciphise umphumela wokuvikela, kukhuphuke ukumelana nokuphefumula, futhi umphumela awuwona kuhle.

Yini ukusetshenziswa kwe-valve yokuphefumula kumaskhi?
Imaski ngaphandle kwe-valve yokuphefumula yenziwa ngendwangu yokuphefumula nokuvimba i-PM2.5. Siyini isimiso semaski nge-valve yokuphefumula?
Kunokuqagela okuthathu okungenzeka kususelwa ekutheni ipuleti levalve nendwangu ziyaphefumula yini:
A. indwangu iyoba nomoya oqinile ngangokunokwenzeka, futhi ukuhlunga kuzotholwa ngepuleti le-valve ku-valve yokuphefumula. Lapho uhogela, umoya ungadlula ku-valve plate, kuyilapho i-PM2.5 nezinye izinhlayiya zivinjelwe; lapho ukhishwa, ipuleti le-valve liyavulwa futhi lingene nomoya ngokuphelele
B. indwangu iyefana nesifihla-buso ngaphandle kwe-valve yokuphefumula, esebenza kuphela njenge-valve yendlela eyodwa futhi engangeni emoyeni. Lapho uhogela, i-valve ivinjwe ngokuphelele futhi ivaliwe; lapho ukhishwa, i-valve iyavulwa futhi ifakwe umoya ngokuphelele
I-C. I-valve yefabric ne-breather inomsebenzi "wokungenisa umoya nokuvimba i-PM2.5"
