摘　　要：煤矿掘进巷道湿式喷射混凝土液体速凝剂添加器价格高,速凝剂添加精度控制复杂。主要介绍一种带转动控制阀的液体速凝剂添加器的原理和主要结构,以及样机与矿用滚子挤压泵送型湿式混凝土喷射机配套应用。Most setting accelerator adder used for jetting wet concrete liquid onto the colliery tunnels has high price and complex control in the adding accuracy of setting accelerator. The paper introduced a kind of setting accelerator adder equipped with rotary control valve about its principle and main components, and described the matching application of the prototype with mine-used roller squeeze pump-feeding wet concrete sprayer.
