Technical Field

The invention belongs to the field of cleaning and detecting of natural gas pipelines, and particularly relates to a brake speed regulating device for a gas pipeline cleaner, which can effectively reduce the running speed of the cleaner and improve the cleaning efficiency and the accuracy of a detection result.

Background

Periodic pigging and inspection of natural gas pipelines has become a standard industry procedure. The pigging operation requires that the pipe pig move at a near steady, moderate speed, otherwise the test data may be lost, resulting in a pig failure. When a pipe cleaner is used for cleaning pipes, the natural gas pipeline is generally limited to 2-7 m/s, and the excessive high speed and the excessive low speed are not beneficial to the operation; in order to obtain better detection data quality, the detection equipment in the pipeline requires that the running speed of the equipment is lower than 5 m/s; the electromagnetic ultrasonic detection equipment requires the running speed to be lower than 2 m/s. When the pipe cleaner passes through a large inclination angle and a fluctuated pipeline, the speed change is large, and the requirement of speed control cannot be met by directly using a conventional pipe cleaner.

The speed control mode of the pig can be an active control mode and a passive control mode.

The principle of the active control mode is to control the running speed of the pipeline pig through a mechanism of the active control mode. Currently, the active control method mainly uses an internal bypass valve to control the pressure difference between the front end and the tail end of the pipe cleaner, and adjusts the pushing force of the pipe cleaner, so as to control the running speed of the pipe cleaner.

The principle of the passive control mode is to indirectly control the speed of the pipe cleaner by controlling the pressure and flow of the medium at the inlet end and the outlet end in the pipe cleaning operation. Because of the compressibility of the gas, it is often difficult to achieve a better velocity control effect in a passive control manner.

The research on the pipe cleaner brake speed regulation device at home and abroad is not a lot, and the pipe cleaner brake speed regulation device mainly takes a hydraulic system as driving force to drive a corresponding mechanism to enable a roller to be pressed on the inner wall of a pipeline, so that the speed reduction effect is achieved. The brake speed regulating device using the hydraulic system as the driving force at present mainly has the following defects: (1) due to factors such as oil leakage of a hydraulic system and the like, pipelines can be polluted, and the stability and the correctness of movement are influenced, so that the hydraulic transmission cannot ensure a strict transmission ratio; (2) in order to reduce leakage and meet certain performance requirements, the manufacturing precision requirement of a matching piece of the hydraulic element is high, and the machining process is complex; (3) the hydraulic transmission requires a separate energy source, and is not convenient to use like a power supply; (4) the hydraulic system is not easy to check and eliminate when in fault.

At present, the electric cylinder drives a pipe cleaner which consumes electric energy, and the electric quantity of a storage battery is limited, so that the cleaning of a long-distance natural gas pipeline is limited.

Therefore, the development of the pipe cleaner active controller with wider application working conditions has important significance and application prospect.
