| 摘 要： | 为了分析拍门的水力特性,以上翻式和侧翻式拍门为研究对象,应用Pro/E软件进行三维建模,应用Fluent软件对拍门开启角度为30°、40°及50°的出水流态进行数值模拟,得到了两种拍门的水力损失值。研究结果表明,侧翻式拍门克服了传统上翻式拍门的缺陷,拍门开启角度大,在同种工况下侧翻式拍门的水力损失更小,水流流态更好。

| Abstract: | In or der to ana lyze the hydraulic characterist ics of flap valve, t he upturning and side2dump flap valves w ere used as the
research object, the three2dimensional mo del of fla p va lve w as developed using Pro / E softw are and the numerica l simulat ion of
outlet flow patter n w as conducted using Fluent softw are under three opening ang les of flap valv e: 30b, 40b , and 50b. T he hydrau2
lic lo sses of t he tw o flap v alv es w ere o btained. T he r esear ch r esults pr ov ed that the side2dump flap v alve over comes the disad2
v antag es of tr adit ional upturning flap v alv e in that it has a bigg er opening angel, low er hydraulic lo ss, and bet ter flow patter n
under the same w or king conditions. |
