Isikhokelo sokukhetha ivalve yokungena manzi
Iivalvu zokungena manzi ziyinxalenye yemveliso yanamhlanje kunye neemveliso zabathengi. Abagcini nje ukukhusela izixhobo kumswakama, kodwa baqinisekisa ukuba izixhobo ziphefumula, ngaloo ndlela zandisa ubomi benkonzo yemveliso. Phakathi kweevalvu ezininzi zokungenisa umoya ezingenamanzi, i-e-PTFE (i-polytetrafluoroethylene eyandisiweyo) iivalvu zokungena manzi zingangeni zithandwa ngenxa yokusebenza kwazo okugqwesileyo. Namhlanje, siya kukunika uhlalutyo olunzulu lwemigaqo yokukhetha ye-e-PTFE i-valve ye-ventilation engangeni manzi.e-PTFE yimathiriyeli ehamba phambili eyaziwayo ngesakhiwo sayo esisodwa se-micropores ezincinci ngokwaneleyo ukuvala amanzi kunye nolunye ulwelo ngelixa zikhulu. ngokwaneleyo ukuvumela iigesi ukuba zidlule ngokukhululekileyo. Olu phawu lwenza i-e-PTFE ibe lolona khetho lufanelekileyo lokwenziwa kweevalvu zepermeator ezingangeni manzi.
Umgaqo wokhetho:
- Ukuziqhelanisa nokusingqongileyo: Qwalasela iimeko zokusingqongileyo esiya kujongana nazo isixhobo, ezifana nobushushu, ukufuma, ukuvezwa kweekhemikhali, njl njl. Izinto ze-e-PTFE zisebenza kakuhle phantsi kwezi meko zinzima, kodwa iimpawu ezithile zisafuna ukuvavanywa ngokuchasene neenkcukacha zemveliso.
- Iimfuno zokungena komoya: Khetha ubungakanani obufanelekileyo bokungena komoya ngokobungakanani bobushushu kunye nokufuma okuveliswa sisixhobo. Ukungena komoya okugqithisileyo kunokubangela ukuba ukufuma kungene, ngelixa ukungeneka komoya okuphantsi kakhulu kunokuchaphazela ukusebenza kakuhle kokutshatyalaliswa kobushushu kwesixhobo.
- Ubungakanani kunye nofakelo: Qinisekisa ukuba ubungakanani bevalve yokukhupha umoya iyahambelana nojongano lwesixhobo, kwaye ucinge ngokulula kunye nokhuseleko lofakelo, kukho iindlela ezimbini zokufakela isikrufu kunye nofakelo lwekliphu.
- Iimfuno zokuhamba: Ukusetyenziswa okudinga utshintshiselwano olukhawulezayo lwegesi, khetha ivalve ye-vent enomthamo ophezulu wokuhamba.
- Ukuqina: Qwalasela ukuqina kokuvezwa kwexesha elide kwindawo enzima kwaye ukhethe ivalve ye-vent echasene nokukhanya kwe-ultraviolet, iikhemikhali kunye nezinye izinto zokhukuliseko.
Inkcazo yethiyori: Umgaqo osebenzayo wevalve yokungena kwamanzi usekelwe kwisakhiwo sayo se-microporous. Xa iimolekyuli zomphunga wamanzi zizama ukudlula kwezi micropores, zithintelwa kukujiya zibe ngamathontsi amanzi ngenxa yesenzo sokuxinana komphezulu. Ngelo xesha, iimolekyuli zegesi zinokudlula ngokukhululekileyo, zigcina ukuphefumla kwesixhobo.
