Abstract

The invention relates to an automatic speed adjusting pipe cleaner for a natural gas pipeline, and aims at solving the problem of the existing battery-based control method of driving a bypass valve with a motor. The automatic speed adjusting pipe cleaner is of a pure mechanical structure. According to the technical scheme, the automatic speed adjusting pipe cleaner is characterized in that the inner wall of a pipeline is compressed by a speed acquisition wheel; the speed acquisition wheel drives a center shaft to rotate by a belt transmission manner, and the center shaft rotates to drive a mass block to rotate to control the opening degree of a throttling valve through the eccentric force of the mass block, and the throttling valve can also be automatically adjusted based on the speed. The speed controller is simple in structure, is not provided with any electrical apparatus element, is safe and reliable, and can be applied to long-distance cleaning of the natural gas pipeline; a pipe detection device can be carried.

Description

technical field [0001] The invention relates to an automatic speed-regulating pig for natural gas pipeline pigging. Background technique [0002] In the process of pigging and testing natural gas pipelines, general regulations require that the running speed of pigging equipment is 3.5-5m / s; in order to obtain better quality of testing data, the testing equipment in the pipeline requires the running speed of the equipment 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. Conventional pigs cannot meet the speed control requirements. [0003] Existing natural gas pipeline pig speed control methods are divided into passive control methods and active control methods. The passive control method is to indirectly control the sp...
