摘　　要：针对管道检测设备在高流速天然气环境下运行时存在的清管效率低、检测精度差等问题,通过分析检测设备在天然气管道中的运行特点及国内外常用的检测设备调速方法,指出搭载速度控制装置可有效降低检测设备的运行速度,减小速度波动幅值。从理论研究、样机试验和泄流阀结构3个方面详细阐述了基于泄流阀调速的速度控制装置的最新研究进展,分析了泄流阀调速装置的组成、工作原理及常用结构形式。指出未来对泄流阀调速装置的研究,应重点分析泄流阀开口形式、开口大小与泄流阀损失系数之间的关系。另外,对速度控制装置失效后利用安全闭锁装置保证检测设备继续运行的研究也是未来的发展方向。When a pipeline detection device is used in natural gas environment of high flow rate, its pigging efficiency and detection accuracy are both low. In order to solve these problems, the operational characteristics of detection devices in natural gas pipelines and the speed control methods that were commonly used for detection devices at home and abroad were analyzed. Result indicates that the carrying speed control device can effectively reduce the running speed of detection devices and the fluctuation amplitude of speed. The latest research progress of speed control devices based on bypass valves was overviewed in detail from the aspects of theoretical research, prototype tests and bypass valve structures. The composition, principle and commonly used structure forms of the speed control device based on bypass valve were analyzed. Results indicate that the future research on speed control devices based on bypass valve shall be focused on the relationship between loss coefficient of bypass valve and its opening forms and sizes. Besides, it is necessary to study how to keep the detection devices running continuously using safe lockout devices when speed control devices fail. （7 Figures, 1 Table, 42 References）
