Abstract

The invention relates to a bypass valve type speed regulating pipe cleaner. The defects of an electronic control bypass valve control mode can be overcome. According to the technical scheme of the bypass valve type speed regulating pipe cleaner, a speed acquisition wheel is pressed on the inner wall of a pipe through spring force and hydraulic force and drives a hydraulic pump, the hydraulic pump outputs high-pressure oil, the high-pressure oil flows back to an oil tank through a throttling valve, front end pressure of the throttling valve is introduced into an oil cylinder, the oil cylinder pushes a throttling barrel to slide, and the throttling valve is opened. According to the pipe cleaner, no electrical component exists in a speed controller, safety and reliability are achieved, a storage battery is not needed for energy storage, the pipe cleaner can be used for long-distance pipe cleaning, pipe detection equipment can be carried, and work of pipe detection and pipe cleaning is completed.

Description

technical field [0001] The invention relates to a bypass valve type speed regulating pipe pig. Background technique [0002] In the process of pigging and testing oil and gas pipelines, general regulations require that the running speed of the pigging equipment is 3.5-5m / s; in order to obtain better quality of testing data, the running speed of the testing equipment in the pipeline is required to be lower than 5m / s ; Electromagnetic ultrasonic testing equipment requires its operating speed to be lower than 2m / s. The speed of the pigs changes greatly when passing through the uphill and downhill sections, curved sections, liquid accumulation, sand accumulation and fouling sections of the pipeline, and the direct use of conventional pigs cannot meet the speed control requirements. [0003] The speed control modes of existing oil and gas pipeline pigs are active control mode and passive control mode. [0004] The active control adopts the bypass valve control method, and its t...
