Technical Field

This novel frock that belongs to, concretely relates to portable pipeline pressure testing, washing frock.

Background

According to the national standard and design requirements, after the pipeline system is installed and before formal debugging, the pipeline system needs to be subjected to functional tests, the strength and the sealing property of the pipeline are checked, and dirt and impurities in the pipeline are removed, so that the system meets the specified cleanliness requirement and strength requirement, and conditions are created for the formal debugging of the system.

In a certain high-throughput test pile under construction installation stage, pipeline functional tests mainly comprise pipeline pressure test and pipeline flushing, the tests require a power source to inject media into a pipeline, and the closest prior art of a medium injection method is to install a temporary water injection power source at a designated position beside a storage water tank and convey the media into an operation pipeline. However, because 66 pipeline systems of a certain under-construction high-throughput test reactor are distributed in 6 plants and 4 ditch sections, and an on-site water production workshop and a storage pool are not constructed, the prior art cannot be used for pipeline pressure test and flushing operation. It would be very costly if provision were made for the prior art to build temporary storage ponds on site and to run temporary pipes to them from water production plants several kilometers away. If the plastic barrel is used for transporting media and is used as a temporary storage water source, continuous operation of a power source cannot be met due to the limitation of the capacity of the plastic barrel, and in addition, the plastic barrel has higher safety risk and larger hidden danger in the long-distance transporting process, so that the plastic barrel is not feasible to be used as a temporary storage water pool.
