Problems solved by technology
However, the pointed object crushing method is very easy to cause damage to the deformed and raised position of the pipeline, resulting in pipeline leakage; the high-pressure jet method requires specific construction equipment, and can only clean short-length pipelines, and is not suitable for some specific construction occasions
Although the self-destruct method can ensure the normal flow of fluid after the pipeline is unstuck, it cannot continue the pigging work

Embodiment Construction
[0021] Such as Figure 1 to Figure 9 As shown, the water-vapour conversion automatic unjamming type pipeline pig includes: a centralizing device 1, a washer 2, and a pig main shaft 3; along the forward direction of the water-vapor conversion automatic unjamming type pipeline pig, the centralizing device 1 is fixed by the washer 2 On the pig main shaft 3, the righting device 1, the washer 2, and the pig main shaft 3 are fixed and arranged sequentially along the same axis from front to back; After the conversion of the automatic jam-releasing type pipeline pig is blocked, the overall tilt will be caused, and it can be straightened through the inflation and expansion process of the air bag 5 located outside the centralizing device 1, and finally the automatic jam release is completed.
[0022] Such as figure 1 , Figure 5 As shown, the main shaft 3 of the pipe cleaner is a cavity structure, four leather cups 15 are fixedly arranged on the outer wall of the main shaft 3 of the p...

The invention belongs to the technical field of pipeline system pipeline cleaning, and particularly relates to a water vapor conversion automatic releasing type pipeline cleaning device. In the forwarding direction of the water vapor conversion automatic releasing type pipeline cleaning device, a centralizing device, a gasket ring and a pipeline cleaning device spindle are sequentially and fixedly arranged along the same axis from front to back; and the pipeline cleaning device spindle is a main body of the water vapor conversion automatic releasing type pipeline cleaning device, after the water vapor conversion automatic releasing type pipeline cleaning device is clamped and blocked, whole inclining is caused, centralizing of the water vapor conversion automatic releasing type pipeline cleaning device can be achieved through the inflation and expansion process of an air bag on the outer side of the centralizing device, and finally automatic releasing is completed. Compared with the prior art, clamping and blockage treatment of the pipeline cleaning device does not need human intervention, a control module can judge the state of the pipeline cleaning device according to data transmitted by a leather bowl pressure sensor, and after it is determined that the pipeline cleaning device is clamped and blocked, the releasing operation is automatically implemented; and after the pipeline cleaning device is released, the cleaning task can be continuously completed, and the pipeline body cannot be damaged.
Description
technical field [0001] The invention belongs to the technical field of pipeline system pigging, and in particular relates to a water-vapour conversion automatic de-jamming type pipeline pig. Background technique [0002] Pipe pigs are one of the effective tools for cleaning pipelines. They are suitable for cleaning various pipelines, and they are non-corrosive to pipelines. Compared with chemical flushing and high-pressure water flushing, they have unique advantages. However, the use of pigs has brought some problems, among which the most likely failure is the blockage of the pigs. After the pig is stuck, it is difficult to locate, and cutting or changing the pipe will cause huge losses. How to deal with the fault of the pig is a topic that needs to be explored. [0003] Existing anti-jamming technologies for pigs mainly focus on the three aspects of reverse recovery, head-on assault and self-destruction of the pig. The reverse recovery method is generally only suitable fo...
