Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a thermal pipeline pressure detection device. Background Art

[0002] Thermal pipeline is a pipe network system used to transmit heat energy. It is usually composed of pipes covered with an insulation layer and transfers heat energy by transporting heat media (such as water, steam or other heat carriers). Thermal pipeline systems are widely used in heating, cooling and industrial production, providing centralized heating and cooling energy for many cities and buildings. Thermal pipelines need to be pressure tested after production.

[0003] Currently, when conducting pressure testing on thermal pipelines, a water pressure testing method is usually adopted. After closing both ends, the inner wall of the tested pipeline is filled with water and pressure is applied. However, when testing pipelines with larger inner diameters, it takes a long time to fill the inside of the pipeline with water, which reduces the efficiency of pipeline pressure testing.

[0004] Therefore, it is necessary to propose a new type of thermal pipeline pressure detection device. Utility Model Content

The water in the water tank can be drawn through the water pumping pipe by the pump body and then delivered to the water delivery pipe.

[0010] Preferably, a first electric push rod is fixedly connected to the top of the support plate near the center position, and a driving end of the first electric push rod movably penetrates the top of the support plate, and an upper fixed block is fixedly connected to the driving end of the first electric push rod, and a support frame is fixedly connected to the bottom of the support plate, and a lower fixed block is fixedly connected to the front surface of the support frame near the bottom, and a plurality of balls are provided on the outer surfaces of the lower fixed block and the upper fixed block.

In the utility model, the first electric push rod, the second electric push rod, the lower fixed block, the upper fixed block and the support plate are used in combination to set the upper and lower limits on the detected pipeline, and then the pipeline is moved to the water tank to quickly fill the inside of the pipeline with water.
