摘　　要：在总结现有试验技术的基础上,研制了新型的制动管件气密性试验台,详细分析了该试验台的结构及组成,对关键部件进行了设计选型,并阐述了试验方法。该试验台操作简单、方便,且易维修。采用该试验台后,降低了劳动强度,提高了工作效率。其在管件、阀件气密性试验方面具有一定的推广应用意义,目前,已广泛应用于铁道机车车辆的各类管件、阀件的气密性试验中。本技术的关键点是定位装夹装置和气缸升降系统的设计结构。On the basis of the existing testing technology,a new type air tightness test stand for brake fittings was de veloped. This paper mainly illustrated the structure, makeup, key components choosing, operation method of the test- stand. The test-stand can reduce labor intensity, and improve working efficiency. The test-bed can be recommended for ai~ tightness test of pipe and valve. At the present time, it has been widely used for air-tightness test of pipe and valve of loco- motive and rolling stock. It has the advantages of convenient operation and maintenance. Its key technologies are positioning and [ixing device and air cylinder elevating system.
