Detailed Description
The low pressure pipeline purging device of the present invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 8, the utility model discloses a low pressure pipeline sweeps device, including spray gun 1 and shower nozzle 5, the front end of spray gun 1 is equipped with shower nozzle 5, still includes dust detector 3, test tube 4 and air supply subassembly 6, and dust detector passes through support 2 to be installed at spray gun 1 front end. One end of the detection tube 4 is connected with the dust detector 3, the other end of the detection tube 4 is connected with a detection tube joint 52 at the front end of the spray head main body 51, an air supply assembly 6 for preventing dust accumulation is arranged on the spray head 5, the air supply assembly 6 is connected with an air pump through a low-pressure pipeline, and the air supply assembly sweeps the dust accumulated in the spray head to prevent the spray gun from being blocked.
As shown in fig. 3 and 4, the blowing assembly 6 includes a blowing box 61 and a blowing pipe 62, a plurality of blowing boxes 61 are uniformly arranged on the outer circumferential wall of the nozzle 5, and the number of blowing boxes 61 can be set according to actual use requirements. As shown in fig. 5 and 6, four air supply boxes are arranged on the outer circumferential wall of the nozzle, and are uniformly arranged on the outer circumferential wall of the nozzle, so that the inner cavity of the nozzle is simultaneously purged through the four air supply boxes.
