Igayidi yokukhetha ivalvu yokungena manzi
Ama-valve angenawo amanzi ayingxenye ebalulekile yemikhiqizo yesimanje yezimboni nezabathengi. Abagcini nje ukuvikela imishini kusuka kumswakama, kodwa futhi baqinisekisa ukuthi imishini iphefumula, ngaleyo ndlela yandisa impilo yesevisi yomkhiqizo. Phakathi kwamavalvu okungenisa komoya amaningi angangeni manzi, ama-e-PTFE (expanded polytetrafluoroethylene) amavalvu okungenisa umoya angangeni amanzi athandwa ngokusebenza kwawo okuhle kakhulu. Namuhla, sizokunikeza ukuhlaziywa okujulile kwezimiso zokukhetha zama-e-PTFE ama-vantilation ventilation valves.e-PTFE iyinto ethuthukisiwe eyaziwa ngesakhiwo sayo esiyingqayizivele sama-micropores amancane ngokwanele ukuvimba amanzi nolunye uketshezi kuyilapho zikhulu. okwanele ukuvumela amagesi ukuba adlule ngokukhululeka. Lesi sici senza i-e-PTFE ibe inketho ekahle yokwenziwa kwamavalvu angenawo amanzi.
Umgomo wokukhetha:
- Ukuvumelana nezimo zemvelo: Cabangela izimo zemvelo impahla ezobhekana nazo, njengezinga lokushisa, umswakama, ukuchayeka kumakhemikhali, njll. Izinto ze-e-PTFE zisebenza kahle ngaphansi kwalezi zimo ezimbi kakhulu, kodwa izakhiwo ezithile zisadinga ukuhlolwa ngokumelene nemininingwane yomkhiqizo.
- Izidingo zokungena komoya: Khetha inani elifanele lokungena komoya ngokuya ngenani lokushisa kanye nomswakama okhiqizwa imishini. Ukungena komoya okweqile kungabangela umswakama ukuthi ungene, kuyilapho ukungena komoya okuphansi kakhulu kungase kuthinte ukusebenza kahle kokukhipha ukushisa kwedivayisi.
- Usayizi nokufakwa: Qinisekisa ukuthi usayizi wevalvu yokukhipha umoya uyahambisana nesixhumi esibonakalayo sezinto zokusebenza, futhi ucabangele ukunethezeka nokuphepha kokufaka, kunezindlela ezimbili zokufaka isikulufu nokufakwa kwesiqeshana.
- Izidingo zokugeleza: Kuzinhlelo zokusebenza ezidinga ukushintshaniswa kwegesi okusheshayo, khetha ivalvu yokukhipha umoya enamandla okugeleza okuphezulu.
- Ukuqina: Cabangela ukuqina kokuchayeka isikhathi eside ezindaweni ezinokhahlo bese ukhetha ivalvu yokukhipha umoya ukumelana nokukhanya kwe-ultraviolet, amakhemikhali nezinye izici zokuguguleka.
Incazelo yethiyori: Umgomo wokusebenza we-valve yokungena amanzi usekelwe esakhiweni sayo se-microporous. Lapho amangqamuzana omusi wamanzi ezama ukudlula kulawa ma-micropores, avinjwa ukujiya abe amaconsi amanzi ngenxa yesenzo sokushuba kwamanzi. Ngesikhathi esifanayo, ama-molecule egesi angadlula ngokukhululeka, agcine ukuphefumula kwedivayisi.
