[0002] Many of the media transported in chemical pipelines are toxic, flammable and explosive. Therefore, pressure testing of industrial pipelines is an important step to ensure the smooth progress of pipeline construction and a prerequisite for ensuring pipeline safety.

[0003] Traditional industrial pipeline pressure testing usually adopts the method of testing one by one. There are many pipelines in the chemical pipeline corridor, and the low, medium and high pressures in the pipelines are widely dispersed. The inlet and outlet positions on the pipelines are different. The detection method of testing one by one requires repeated moving and installation and disassembly of the detection equipment, which is inefficient and affects the progress. Utility Model Content

[0016] Optionally, an eight-shaped blind plate is provided on the main pipe between the multiple pressure test branches.

[0017] By adopting the above technical solution, the number of pressure test branches opened can be controlled according to the number of pipelines to be tested, thereby achieving the effect of energy saving and emission reduction.

[0020] Optionally: an exhaust valve is provided on the branch pipe body.

[0021] By adopting the above technical solution, before injecting water into the branch pipe body, the exhaust valve discharges the residual gas in the branch pipe body, thereby improving the detection accuracy.

[0022] Optionally: a branch hose is provided on one end of the branch pipe body close to the pipeline.

[0023] By adopting the above technical solution, the position of the branch pipe body can be adjusted according to the position of the pipeline and the water inlet on the pipeline, which has a wide range of applications and strong practicality.

An eight-shaped blind plate 3 is installed between the six pressure test branches 2 on the main body 11. The control assembly 4 includes a control box 41 and a display 42 installed on the vehicle body 5, wherein the control box 41, the display 42, the pressure test main pipe 1 and the pressure test branch pipe 2 are all electrically connected.

[0031] During inspection, the vehicle body 5 is parked at a predetermined position, and the eight-shaped blind plate 3 is opened or closed according to the number of pipelines, so as to control the number of pressure test branch pipes 2 in use, and the pressure test branch pipes 2 are connected to the corresponding number of pipelines respectively. Under the control of the control box 41, the pressure test water flow passes through the pressure test main pipe 1 and the pressure test branch pipe 2 in turn and then enters the pipeline. Multiple pipelines can be inspected at the same time, and the inspection data is displayed on the display 42, which improves work efficiency.

[0032] The pressure test pipe 1 includes a pipe body 11 fixedly connected to the vehicle body 5, and the pipe body 11 extends along the length direction of the vehicle body 5. A water pump 12 and a plug 13 are respectively installed at both ends of the pipe body 11, and the water pump 12 and the pipe body 11 are connected through a main hose 17. A first main solenoid valve 14 and a steam trap 16 are installed at one end of the pipe body 11 close to the water pump 12, and a second main solenoid valve 15 is installed at one end of the pipe body 11 close to the plug 13.

[0033] After parking the vehicle body 5 at the predetermined position, adjust the position of the water pump 12 according to the position of the water source, and adjust the first main solenoid valve 14 and the second main solenoid valve 15 to the highest test pressure value. Turn on the water pump 12, the first main solenoid valve 14, the steam trap 16 and the second main solenoid valve 15, and the water flows into the main pipe body 11, and the steam trap 16 discharges the water vapor in the main pipe body 11.

[0034] The main hose 17 is often bent and easily damaged, so in this embodiment, a flange 18 is fixedly connected to one end of the main hose 11 near the main hose 17, a perforated blind plate 19 is fixedly connected to the flange 18, and the end of the main hose 17 is threadedly connected to the perforated blind plate 19.
