Amavalvu adlala indima ebalulekile ekulawuleni ukugeleza koketshezi namagesi ezinqubweni ezihlukahlukene zezimboni.Ukuqinisekisa ukusebenza kahle nokuphepha, kubalulekile ukuqonda ukuphuma kwe-valve nomthelela wawo ekusebenzeni kahle kwesistimu nokusebenza kahle.Kule bhulogi, sizohlola konke odinga ukukwazi mayelana nokuphuma kwama-valve.
Kuyini ukuphuma kwe-valve?
Okukhipha i-valve umthamo woketshezi i-valve engakwazi ukuyilawula noma ukuyilawula njengoba idlula ohlelweni.Lokhu okukhiphayo kukalwa ngamayunithi ahlukene kuye ngohlelo lokusebenza.
Ukukhishwa kwe-valve kuvame ukuhlukaniswa ngobukhulu bayo, ukuma kanye nezinto zokwakha.I-valve enkulu inamandla okukhipha aphezulu kune-valve encane, okusho ukuthi ingalawula umthamo omkhulu woketshezi noma igesi.
Ngaphezu kosayizi, uhlobo lwe-valve luphinde luthinte amandla ayo okukhipha.Amanye ama-valve aklanyelwe ukuphatha izinhlobo ezithile zoketshezi noma amagesi, okusho ukuthi angalungiselelwa izinhlelo ezithile.
Ukuqonda Ukugeleza Kwe-Valve
Ukugeleza kwe-valve kungenye into ebalulekile yokuphuma kwe-valve.Uma i-valve ivuliwe, ivumela uketshezi noma igesi ukuthi idlule futhi ingene ohlelweni.Umthamo woketshezi noma igesi edlula kuvalvu ubizwa ngokuthi ukugeleza.
Ukugeleza kwe-valve kungaba yi-laminar noma i-turbulent.Ukugeleza kwe-laminar kubonakala ngokunyakaza okubushelelezi, okuzinzile, kuyilapho ukugeleza kwesiyaluyalu kubonakala ukunyakaza okusheshayo, okunesiphithiphithi.
Ezimweni eziningi, ukugeleza kwe-laminar kukhethwa ngaphezu kokugeleza kwe-turbulent ngoba kubikezelwa futhi kulula ukukulawula.Nokho, ezinye izinhlelo zokusebenza zidinga ukugeleza kwesiyaluyalu, njengalapho uketshezi noma amagesi kudingeka kuxutshwe noma kunyakaze.
Izinto Ezithinta Okukhiphayo Kwevaluvu
Izici eziningi zingathinta ukuphuma kwe-valve.Lokhu kubandakanya:
1. Ukucindezela: Izinhlelo zokucindezela okuphezulu zidinga ama-valve angakwazi ukuphatha imithwalo eyengeziwe.
2. Izinga lokushisa: Okunye okusamanzi namagesi kuyazwela, futhi amavalvu kufanele aklanywe ukuze amelane namazinga okushisa aphakeme.
3. I-Viscosity: I-Viscous noma i-viscous fluids idinga ama-valve angakwazi ukubhekana nokwanda kokumelana nokucindezela.
4. Uhlobo loketshezi noma igesi: Okunye uketshezi namagesi kunezinto zamakhemikhali ezihlukile ezingathinta ukusebenza kwamavalvu.
Ngokuqonda lezi zici, ungakhetha i-valve ezohlinzeka ngokusebenza okungcono kakhulu, impilo yesevisi nokuphepha.
Ekuphetheni
Ukukhishwa kwe-valve kuyisici esibalulekile ekusebenzeni kwenqubo yezimboni nokuphepha.Lapho ukhetha i-valve yohlelo lwakho lokusebenza, izici ezifana nosayizi, uhlobo, ukugeleza, ingcindezi, izinga lokushisa kanye ne-viscosity kufanele kucatshangelwe ukuze kuqinisekiswe ukusebenza kahle nokuphepha.
Uhlome ngalolu lwazi, ungakhetha i-valve ehlangabezana nezidingo zakho eziyingqayizivele futhi inikeza ukusebenza okuthembekile, okuhlala isikhathi eside.
