1. Umsindo okhiqizwe ngokudlidliza okwenziwe ngomshini:Izingxenye zokucindezela kwegesi okunciphisa i-valve kuzokhiqiza ukudlidliza okwenziwe ngomshini lapho uketshezi luhamba. Ukudlidliza Kwemishini kungahlukaniswa ngezindlela ezimbili:
1) Ukudlidliza okuphansi okuphansi. Lolu hlobo lokudlidliza lubangelwa yi-jet kanye nokujaha okuphakathi. Isizathu ukuthi i-flow velocity ephumayo e-valve ishesha kakhulu, ukuhleleka kwamapayipi akunangqondo, futhi ukuqina kwezingxenye ezishukumisekayo ze-valve akwanele.
2) Ukudlidliza okuthe xaxa. Lolu hlobo lokudlidliza luzodala ukubumbana lapho imvamisa yemvelo ye-valve ihambisana nemvamisa yokuxoxa okubangelwa ukugeleza okuphakathi nendawo. Kukhiqizwa umfutho womoya ocindezelwe ukunciphisa i-valve ngaphakathi kwebanga elithile lokucindezela, futhi uma izimo zishintsha kancane, umsindo uzoshintsha. Omkhulu. Lolu hlobo lomsindo wemishini lokudlidliza alunakwenza lutho ngejubane lokugeleza kwe-medium, futhi libangelwa kakhulu ukwakhiwa okungenangqondo kwengcindezi enciphisa i-valve uqobo.
2. Kubangelwa ngumsindo we-aerodynamic:Lapho uketshezi olucindezelayo olufana noSteam ludlula ngokucindezela kwengcindezi ekucindezelweni okunciphisa i-valve, umsindo okhiqizwe amandla omshini we-fluid uguqulwa waba amandla we-aerodynamic. Lo msindo ngumsindo onenkinga kakhulu ebangela iningi lomsindo wengcindezelo enciphisa i-valve. Kunezizathu ezimbili zalo msindo. Enye ibangelwa isiphithiphithi esiffuyo, kanti enye ibangelwa amaza ashaqekile abangelwa uketshezi olufinyelela ku-velocity elibucayi. Umsindo we-aerodynamic awukwazi ukuqedwa ngokuphelele, ngoba ingcindezi yokunciphisa i-valve ibangela isiyaluyalu se-fluid lapho kunciphisa ingcindezi akunakugwenywa.
3. Umsindo we-fluid dynamics:I-Fluid Dynamics Noise ikhiqizwa ngesiyaluyalu kanye nokugeleza kwe-vortex ngemuva kokuthi uketshezi ludlula echwebeni lokuphumula lokucindezela lengcindezi yokunciphisa i-valve.
