摘　　要：S管阀是一种广泛用于混凝土喷射机的关键部件,它的性能直接影响混凝土喷射机的使用性能。为了研究分析S管阀内的混凝土压力分布,建立了固液两相流模型,并且应用计算流体力学FLUENT软件在给定条件下进行了模拟分析,分别改变管道直径、曲率半径、流速和固体体积浓度对所建立的模型进行仿真分析,最后确定了各个参数对S管内压力损失的影响程度。S-type tube valve is one of the key components widely used in shoctcreter, of which properties can directly affect the service performance of shoctcreter. In order to a- nalysis the concrete stress distribution in the S-type tube valve, a solid-liquid two-phase flow model was built. Nu- merical simulation of S-type tube valve under the given con- ditions was carried out by using computational fluid dynam- ics software FLUENT. Under the conditions of changing the diameter and radius of curvature of pipe, velocity of flow and solid volume concentration, the built model was simulated, the effect of various parameters on pressure loss in S-type tube valve was determined.
