摘　　要：针对目前因缺乏检测设备导致给水管路系统无法进行冷热水循环试验的现状,研制了一种全自动给水管路系统冷热水循环试验设备。该装置采用双泵增压结构,用两个气动三通阀切换回路,在回路上安装比例溢流阀,通过节流来控制系统压力。同时,设计了一种管材管件快速装夹结构,便于不同规格管路系统部件的快速装卸。详细介绍了设备的工作原理、机械构成、性能参数和工作流程。三年的试验验证结果表明,该套设备操作便捷、运行稳定、参数设计合理,能够满足产品质量保证和标准检测要求。Aiming at the current situation that the cold and hot water cyclic testing can not be carried out for the water supply pipeline system due to lack of testing equipment, an automatic cold and hot water cyclic testing equipment for the pipeline system is developed. The device adopts a double pump pressurization structure, two pneumatic three-way connections are used to switch the circuit, and a proportional relief valve is installed on the circuit to control the system pressure through throttling. A quick clamping structure of pipe fittings is designed to facilitate the rapid loading and unloading of pipeline systems of different specifications. The working principle, mechanical structure, performance parameters and working procedure of the equipment were introduced in detail. Through three-year’s testing, the equipment proved to be easy to operate, stable in operation, reasonable in parameter design, which can meet the requirements of product quality assurance and standard requirements.
