文摘:本文针对固液两相流的特点，建立了水击计算的运动方程及连续方程，并采用新方程对矿山常采用的容积泵输送中使用的储气罐、泄压阀、缓闭逆止阀等减缓水击压力的防护措施进行了计算分析，得出储气罐、泄压阀减压效果最好的结论。 |
| 10. | Xh rubber slowly - closing cut - off vavle is a new water supply and drainage vavle with full rubber structure , duck - mouthed appearance and functions or positive flow - in and reserve cut - off . according to thrust analysis and calculation as well as different operation mechanism and different rubber products by special processing . all will be open at weak hydraulic pressure is higher , the vavle gate will open more greatly and the water flow is greater . at reserve operation , the vavle gate closes naturally and seals tightly cut - off vavle ; the back pressure is higher , the vavle gate closes more tightly and the seal effect is better . it is used widely in various drainage exit to prevent from pouring backwards and flowing backwards in city planning , water conservancy and sewage disposal etc . it is the ideal productto replace flap vavle
Xf型橡胶缓闭逆止阀是一种全橡胶结构外形呈“鸭嘴状” ，具有“正向流入反向逆止”功能的新型给排水阀门产品。它根据受力分析和受力计算，针对不同的工况，采用不同的设计机理，选用不同的橡胶配方，并按特殊工艺制作而成。正向工作时，水由进水口流入，微小的水压，便能打开阀门，水压越大，阀门开启越大，水流量越大。 |
