[0002] Currently in the field of pipeline transportation industry, before the pipeline is used, it is necessary to conduct a water pressure overflow test on the laid pipeline to ensure that the pressure resistance of the water pipe meets the standard and will not be damaged during use.

[0003] At present, a Chinese utility model with announcement number: CN207049444U discloses a water source sampling and delivery pipeline with stable performance, including a first delivery pipe and a second delivery pipe, the first delivery pipe is located on the left side of the second delivery pipe, the right end of the first delivery pipe is fixedly connected to the left end of the second delivery pipe through a compensator, and the outer surface of the first delivery pipe and the outer surface of the second delivery pipe are both placed with a semicircular limit ring, and the inner wall of the limit ring is fixedly connected with an anti-skid pad. The water source sampling and delivery pipeline with stable performance can effectively protect and place the delivery pipeline, effectively avoid the phenomenon of the pipeline breaking, can effectively fix the delivery pipeline, has good stability, can effectively release the impact force of external force and water flow, has better protection effect, can stably support and fix the delivery pipeline, effectively avoid the phenomenon of pipeline tilting, and effectively ensure the normal use of the delivery pipeline.

[0004] The existing transmission pipeline for water pressure test overflow needs to ensure that the diameter of the transmission pipeline is consistent in order to facilitate the connection of different pipe combinations. Therefore, it can only be connected to the conventional output end pipeline of the pressure limiting valve of the same size; at the same time, when the pipeline is transmitting water, when the valve is closed, the water source stops flowing and the water source is easy to freeze in the pipeline in an extremely low temperature environment. The existing method of coating the surface of the pipeline with foam is not ideal and cannot ensure that the water source will not be frozen. Therefore, the transmission pipeline for water pressure test overflow cannot be used during this period, which greatly reduces the practicability of the transmission pipeline. Utility Model Content

[0010] The utility model is further configured as follows: an electric wire electrically connected to the heating wire is fixedly connected to one side of the surface of the first delivery pipe, the second delivery pipe and the L-shaped overflow pipe.

[0011] By adopting the above technical solution, the heating wire can be easily connected to a socket power supply at a remote location through an electric wire.

[0012] The utility model is further configured as follows: a sealing ring is fixedly connected to the inner surface of the reinforcing collar and is respectively slidably connected to the surfaces of both ends of the first conveying pipeline, the second conveying pipeline and the L-shaped overflow pipeline.

[0013] The above technical solution is adopted to improve the sealing performance of the interface and prevent water from seeping out.

[0014] The utility model is further configured as follows: a connecting flange is fixedly installed on one end of the control ball valve away from the second delivery pipeline.

[0015] The adoption of the technical solution facilitates the control of the ball valve and other normal water delivery pipelines to achieve sealed connection.
