背景技术Background technique
据统计，中国管道里程已经超过12万公里，其中有30％以上的管道运行时间大于10 年，存在很大的安全隐患。为保证管道的正常运行，需要定期对管道进行清管和检测作业。清管的目的是清扫管道内的杂物、积液、积污，提高管道输送效率，减少摩阻损失，当清管与检测同时进行时，还可获得管道变形，腐蚀，裂纹等数据并对这些管道缺陷进行精确定位，为后期的管道维护提供可靠信息。目前，主流的清管器主要依靠自身对管道内输送介质的阻滞作用所形成的压差来驱动前进，但由于管道上下游的压力存在波动，特别是近年建成的大口径、高压、高流速长输天然气管道，介质流速已经超过5m/s，瞬间速度可能达到十几米每秒，使得作业装备的运行速度不十分稳定,瞬时运行速度可在0～25m/s之间变化。根据SY/T 5922-2003《天然气管道运行规范》8.7.4.1项规定，“清管器运行速度一般宜控制在3.5m/s～ 5m/s。”当管道作业装备运行速度超过5m/s时，容易出现信号采集不理想,甚至出现检测不到信号的现象,无法完成管道检测任务，更有甚者,由于内检测器运行速度过快,容易造成对管道及运行设备的冲击,造成重大安全事故，损害用户和企业的利益。因此调节内检测器运行速度使其运行在合理的速度范围之内,势必成为在输气管道内检测过程中提高管道检测精度和降低安全事故风险时所面临的问题。According to statistics, China's pipeline mileage has exceeded 120,000 kilometers, and more than 30% of the pipelines have been in operation for more than 10 years, posing a great potential safety hazard. In order to ensure the normal operation of the pipeline, it is necessary to regularly carry out pigging and testing operations on the pipeline. The purpose of pigging is to clean the sundries, liquid accumulation and dirt accumulation in the pipeline, improve pipeline transportation efficiency and reduce friction loss. These pipeline defects are precisely located to provide reliable information for later pipeline maintenance. At present, the mainstream pigs mainly rely on the pressure difference formed by the blocking effect on the transport medium in the pipeline to drive forward. However, due to the fluctuation of the upstream and downstream pressure of the pipeline, especially the large diameter, high pressure, high flow For long-distance natural gas pipelines, the flow velocity of the medium has exceeded 5m/s, and the instantaneous velocity may reach more than ten meters per second, which makes the operating speed of the operating equipment not very stable, and the instantaneous operating velocity can vary between 0 and 25m/s. According to item 8.7.4.1 of SY/T 5922-2003 "Code for Operation of Natural Gas Pipelines", "The operating speed of the pig should generally be controlled at 3.5m/s~5m/s." When the operating speed of the pipeline operation equipment exceeds 5m/s , it is prone to unsatisfactory signal acquisition, or even the phenomenon that the signal cannot be detected, and the pipeline detection task cannot be completed. What's more, because the internal detector runs too fast, it is easy to cause impact on the pipeline and operating equipment, causing major safety hazards. Accidents, damage the interests of users and enterprises. Therefore, adjusting the running speed of the internal detector to make it run within a reasonable speed range is bound to become a problem in improving the detection accuracy of the pipeline and reducing the risk of safety accidents in the process of internal detection of gas pipelines.
目前国内外主流可调节速度的清管器是通过搭载闭环控制的泄流阀实现实时控速，其原理是调节电机驱动的泄流阀的泄流面积来改变清管器的前后压差，从而控制清管器的速度。At present, the mainstream speed-adjustable pigs at home and abroad realize real-time speed control by carrying a closed-loop control relief valve. The principle is to adjust the discharge area of the motor-driven relief valve to change the pressure difference between the front and rear of the pig, thereby Control the speed of the pig.
清管器的泄流阀一般采用转阀结构，由转阀动叶片和转阀静叶片组成，这种结构存在许多问题：一、当转阀阀体受到冲击变形时，叶片间容易发生干涉，使转阀卡住，无法调节清管器的运行速度；二、为满足转阀操作扭矩的需求，清管器需要配置大功率电机，携带大容量电池，这将占用清管器的内部空间，减小泄流通道面积，影响速度的可调性；三、转阀一般安装在清管器的端部，增加了清管器的长度，降低了清管器的弯道通过性；四、转阀静叶片后端流体的流动状态存在突变，使清管器局部绕流损失增大，同时局部绕流还会引发清管器的整体振动，这不仅增大了管道输运过程中的能量损耗，也影响到设备的正常运行。The discharge valve of the pipe pig generally adopts a rotary valve structure, which is composed of a rotary valve moving vane and a rotary valve static vane. There are many problems in this structure: 1. When the rotary valve body is impacted and deformed, interference between the vanes is easy to occur. The rotary valve is stuck, and the running speed of the pig cannot be adjusted; 2. In order to meet the demand for operating torque of the rotary valve, the pig needs to be equipped with a high-power motor and a large-capacity battery, which will occupy the internal space of the pig. Reduce the area of the discharge channel and affect the adjustability of the speed; 3. The rotary valve is generally installed at the end of the pig, which increases the length of the pig and reduces the bend passability of the pig; 4. There is a sudden change in the flow state of the fluid at the back end of the valve vane, which increases the local flow loss of the pig, and at the same time, the local flow will also cause the overall vibration of the pig, which not only increases the energy loss during pipeline transportation , also affect the normal operation of the equipment.
