[0078] Three barrels can be connected through pipe joints on the rear valve body 42, so as to transport three kinds of spraying materials. Three spray heads can be connected through pipe joints and pipes on the front valve body 43, and three kinds of spraying materials are outputted externally. Three rear valve body interfaces (A-C), three valve core flow channels and three front valve body interfaces (A-C) form three channels (A channel, B channel and C channel) respectively. When the material is transported into one of the channels, for example, the spraying material is transported into A channel, the spraying material passes through rear valve body A interface 4201, valve core A inlet 4111, flow channel, valve core A outlet 4121 and front valve body A interface 4301 in sequence, and is then sprayed out through the spray head installed on front valve body A interface 4301, so as to spray the inner wall of the pipeline.
[0079] Further, when the spraying material is conveyed in at least two of the A channel, B channel and C channel, the material can be rotated and sprayed from the corresponding spray head in sequence. Therefore, when the three channels are opened at the same time, the pipe inner wall can be sprayed at the same time, and the mixing treatment can be realized on the pipe inner wall. When the three channels are opened in sequence, the pipe inner wall can be sprayed in sequence, and the pipe inner wall can be sprayed in multiple layers without replacing or cleaning other parts, thereby greatly improving the spraying efficiency of the pipe inner wall.
[0080] In actual use, when only part of the channels need to be used, the unused channels can be disconnected from the unused interfaces on the rear valve body 42, thereby cutting off the inflow of fluid; or the front valve body interface on the front valve body 43 is sealed with a sealing plug for sealing treatment.
[0081] Further, as shown in Figure 7 , the valve core 41 rotates at high speed in the rear valve body 42, in order to avoid leakage of the spraying material, and to avoid material leakage caused by leakage of the valve core inlet 411 and the flow channel 413. Between the rear valve body 42 and the valve core 41, on both sides of the valve core inlet 411, a piston seal 45 is regularly arranged. The valve core inlet is sealed and separated by the piston seal 45.
[0082] Correspondingly, the valve core 41 and the front valve body 43 are also separated by the piston seal 45.
[0083] Further, in order to facilitate the fixing work of the front end of the rear valve body 42, a baffle 46 is regularly arranged between the rear valve body 42 and the front valve body 43. The baffle 46 can separate the rear valve body 42 and the front valve body 43, and can stably fix the front end of the rear valve body 42 in the front end of the rear valve body 42.
[0084] Further, in order to facilitate the communication between the valve core inlet 411 and the valve core outlet 412, the flow channel 413 is punched from the front end / right end of the valve core 41, and the front end hole is sealed by a sealing plug 47. The sealing plug 47 can seal the opening end of the flow channel, and can also facilitate the removal of the sealing plug for cleaning the flow channel.
[0085] Further, in order to facilitate the recording and real-time observation of the spraying image of the pipe inner wall, the upper end of the trolley is regularly provided with a camera module for image recording and a signal transmission module for signal transmission.
[0086] Further, the control circuit module and the control circuit board involved above are regularly arranged and installed in the trolley.
