摘要：

针对输油管道内检测器运行速度控制问题,提出了一种新型的泄流调速装置,该装置由泄流阀座、泄流阀芯、弹簧、导杆等组成.通过分析检测器泄流调速装置在水平管道内的受力情况,建立了泄流调速装置的数学模型.利用数值模拟的方法研究了泄流阀座弧度、泄流阀芯-检测器后端距离以及入口流体速度对管道内检测器运动状态的影响.研究结果表明,在相同边界条件下,流体介质通过检测器时,泄流调速装置前后两端压差、总水头损失系数、流场的湍流动能值与泄流阀座左侧弧度成反比关系,而与右侧弧度成正比关系,当泄流阀座左侧弧度为60° 、右侧弧度为15° 时,各参数均为最小值;入口流体速度的增加会导致泄流调速装置前后两端压差、流场湍流动能值增大,当泄流阀座弧度相同、入口流体速度从0.6 m/s增加到2 m/s时,压差增加了106 290 Pa,湍流动能增加了1.831 m²/s²;泄流阀芯-检测器后端距离与泄流调速装置前后两端压差、检测器速度成反比关系,当阀芯-检测器后端距离从15 mm增加到35 mm时,泄流调速装置前后两端的压差减小了240 Pa.本研究为优化输油管道内检测器的运行性能、提高检测效率提供了重要的理论基础与实践指导.

Abstract:

To address the issue of speed control of in-line detector in oil pipelines, a novel discharge speed-regulation device is proposed, which consists of a relief valve seat, a relief valve core, a spring, a guide rod, and other components. A mathematical model of the discharge speed-regulation device is established by analyzing the force acting on this device in a horizontal pipeline. The influence of the radians of the relief valve seat, the distance between the relief valve core and the back end of the detector, and the inlet fluid velocity on the motion state of the detector in the pipeline is studied using numerical simulation methods. The research results show that under the same boundary conditions, when the fluid passes through the detector, the differential pressure across the discharge speed-regulation device, the total head loss coefficient, and the turbulent kinetic energy of the flow field are inversely proportional to the left radian of the relief valve seat and directly proportional to the right radian. When the left radian of the relief valve seat is 60° and the right radian is 15°, all parameters reach their minimum values. An increase in the inlet fluid velocity will lead to higher pressure differences between the front and back ends of the discharge speed-regulation device, and more turbulent kinetic energy in the flow field. When the radians of the relief valve seat holds constant and the inlet fluid velocity increases from 0.6 m/s to 2 m/s, the differential pressure increases by 106 290 Pa and the turbulent kinetic energy increases by 1.831 m²/s². The distance between the relief valve core and the back end of the detector is inversely proportional to the pressure difference between the front and back ends of the discharge speed regulation device and the speed of the detector. When the distance between the valve core and the back end of the detector increases from 15 mm to 35 mm, the pressure difference between the front and back ends of the discharge speed regulation device decreases by 240 Pa. This paper provides an important theoretical basis and practical guidance for optimizing the operational performance of in-line detectors in oil pipelines and improving detection efficiency.
