摘　　要：为解决管道检测器在天然气流速超过5 m/s的工况下无法使用的问题,需要利用旁通阀进行泄流来调节管道检测器的运行速度。目前的旁通阀多为圆锥形结构,为了增加泄流孔的面积,需要旁通阀圆柱面和圆锥面同时进行泄流,但目前仍缺乏对圆锥形旁通阀压力损失系数的研究。结合已有研究成果,推导出圆锥形旁通阀压力损失系数的计算方程,结合工业现场管道输送参数,可计算泄流后管道检测器的运行速度,与Φ1016和Φ1219管道检测器在工业现场的实际运行速度进行比较,计算值与实际运行速度接近,验证了计算方程的可靠性。In order to solve the problem that the pipeline detector cannot be used when the natural gas flow rate exceeds 5 m/s,bypass valve is necessary to be used to regulate the running speed of the pipeline detector.The current bypass valves are mostly of conical structure,in order to increase the area of the discharge hole,the cylindrical and conical surfaces of the bypass valve are required to discharge at the same time,but research on the pressure loss coefficient of the conical bypass valve is still missing.Based on the existing research results,the calculation equation of the pressure loss coefficient of the conical bypass valve was derived.Combined with the industrial field pipeline transportation parameters,the running speed of the pipeline detector after discharge was calculated.Compared with the actual running speed of theΦ1016 andΦ1219 pipeline detectors in the industrial field,the calculated value is close to the actual operating speed,the reliability of the calculation equation is verified.
