Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0044] Such as figure 1 , 2 As shown, a self-blocking pig with a rotating head and a gas throttling prevention device includes a pipe 1, a leather cup 2, a cylindrical frame 3, an air bag 4, an air bag cavity 5, a spring fixing column 9 and a spring 10 , the pig is in the pipeline 1, the leather cup 2 surrounds the outside of the cylindrical frame 35, the air bag 4 is connected with the spring 10 in the air bag cavity 5, the spring 10 is fixed on the spring fixing column 9, and the pig The device also includes a pigging module, a self-clogging module and a gas throttling prevention module;

[0045] To prevent gas throttling the module prevents throttling as follows:

[0046] k1: the first battery pack 113 outputs a direct current and flows into the inverter 112;

[0047] k2: the current flowing out of the inverter 112 is an alternating curr...

Abstract

The invention relates to a self-deblocking pipe cleaner provided with rotary heads and a gas throttling preventing device. The self-deblocking pipe cleaner integrates multiple functions of two-times pipe cleaning through the rotary heads, automatic deblocking and preventing of ice blockage of bypass holes by hydrates generated by gas throttling. The two rotary heads are designed and can automatically rotate, and ejected high-speed gas is used for conducting comprehensive flushing on the inner wall of a pipeline. The gas throttling preventing device is used for heating gas which flows through the bypass holes through the eddy current effect, and the gas is prevented from blocking a flow channel through ice blockage due to the throttling effect. An automatic deblocking device is designed, and when a speed sensing ball detects that the operation speed of the pipe cleaner is zero, namely blockage occurs, an executing mechanism adjusts a three-way ball valve, and the gas is concentrated at the front end of the de-blocked flow channel to be ejected out at a high speed so as to remove blockage matter in front. The self-deblocking pipe cleaner provided with the rotary heads and the gas throttling preventing device can ideally clean pipes, remove blockage and protect the bypass holes against ice blockage by hydrates generated by gas throttling.

Description

technical field [0001] The invention relates to a self-clogging pipe pig with a rotating head and a gas throttling prevention device, belonging to the technical field of pipeline operations. Background technique [0002] Most of the oil and gas transported by my country's oil and gas pipeline gathering and transportation network contain water and some highly corrosive media, which makes the pipe wall of the pipe network corroded quite seriously. 90% of the corrosion perforation comes from the corrosion of the inner wall of the pipeline. Internal anti-corrosion measures mainly focus on the inner coating of the pipeline, and pigging operations are required before the inner coating of the pipeline. [0003] Steel skeleton straight plate pigs are generally used on large pipelines. This kind of pigs mostly use scraping to clean the inner wall of the pipeline. Scratching is that the leather bowl or wire brush carried by the pig cleans the attachments on the pipe wall, so that the...
