摘　　要：目前动车组、城轨车辆制动控制系统集成板、阀体密封主要有3种形式:钢珠密封、圆柱堵头密封、密封管螺纹密封。钢珠密封和圆柱堵头密封需要将其压装到集成板、阀体内且无法拆卸,而管螺纹密封则具有很好的可拆解性,因此,应用非常广泛。针对密封管螺纹深度控制在设计、装配、验收中的问题进行分析,并在此基础上,得出密封管螺纹深度控制的验收方法。The sealing forms of integrated board and valve block for EMU and metro vehicles＇ brake control system mainly have three kinds：steel ball sealing,cylindrical plug sealing and thread pipe sealing.The steel ball sealing and cylindrical plug sealing are impossible to disassemble,while the thread pipe sealing has good detachability to be commonly used.Aimed at the depth control of sealing pipe thread,this paper analyzes the problems in the process of design,assembly and acceptance,and proposes the acceptance method for the depth control of sealing pipe thread.
