[0040] Combine Figures 1 to 5 As shown, the utility model provides an intelligent multifunctional pipeline flushing and pressure testing device, which includes: a shell body, which is provided with an oil outlet end and an oil return end; an oil tank 1, which is arranged in the shell body; a functional group, which is arranged in the shell body, and the functional group is connected to the oil tank 1, the oil outlet end and the oil return end; the functional group includes a flushing group for flushing the flushed pipeline, a pulse group for pulse flushing the flushed pipeline, a filtering group for filtering the flushing medium refluxed from the flushed pipeline, and a pressure testing group for performing high-pressure testing on the flushed pipeline.

[0041] Specifically, the input end of the flushed pipeline is connected to the oil outlet end, and the output end of the flushed pipeline is connected to the oil return end, so that the intelligent multifunctional pipeline flushing and pressure testing device of the present application forms a loop with the flushed pipeline. When the flushed pipeline needs to be flushed, the flushing group works and inputs the flushing medium from the oil tank 1 into the flushed pipeline through the oil pipeline and the oil outlet end of the device. The pollutants in the flushed pipeline are returned to the oil pipeline of the device through the oil return end along with the flushing medium, and the pollutants and the flushing medium are separated under the filtering action of the filter group, and the flushing medium is returned to the oil tank 1 for recycling.

[0042] In some usage scenarios, in order to achieve a more efficient pulse flushing function for the flushed pipe, the pulse group forms pulses by energizing and de-energizing, so that the flushing medium forms a pulse flow under the operation of the pulse group before entering the flushed pipe, and the pulse flow then enters the flushed pipe through the oil outlet, thereby improving the flushing efficiency and improving the flushing degree of the flushed pipe.

[0043] In some usage scenarios, in order to be able to test the pressure bearing capacity of the flushed pipe, the flushing group works and inputs the flushing medium into the flushed pipe, so that the flushing medium fills the flushed pipe and discharges the air in the flushed pipe and closes the output end of the flushed pipe. Then the pressure test group works and inputs the flushing medium from the oil tank 1 into the flushed pipe through the oil pipeline of this device to realize the pressure test function.

[0044] Compared with the prior art, the present application innovatively integrates the flushing group, pulse group, filter group and pressure test group as well as the oil tank 1 in the shell. By connecting the oil outlet and return ends to the flushed pipeline and starting the device, the flushed pipeline can be flushed, pulse-flushed, and subjected to high-pressure pressure tests as needed.

[0045] It should be noted that an oil outlet ball valve 24 can be provided at the oil outlet end, and an oil return ball valve 25 can be provided at the oil return end.
