Furthermore, a filter plate 42 is arranged at the joint of the liquid passing pipeline 7 and the liquid inlet flange 2.
The working principle is as follows: liquid firstly flows in from the filter pipeline 4, the rotary ball 26 in the filter pipeline 4 is driven to rotate along a certain direction in the process of flowing through the filter pipeline 4, a vortex is formed in the rotating process, a part of liquid flows in through the liquid inlet 41 between the fan blades 43 on the surface of the rotary ball 26, then the part of liquid flows in the liquid through the filter mesh 27 on the outer side of the liquid through pipeline 7 after being filtered, the part of liquid flows in the liquid through pipeline 7, the rotary ball 26 is driven by the liquid to continuously rotate, and therefore the liquid in the liquid through pipeline is driven to continuously move upwards and finally flows in the hydraulic cabin 19, and therefore the hydraulic cabin 19 is gradually filled with the liquid.
The in-process that is full of liquid in hydraulic pressure storehouse 19 will make the outside expansion of flexible body 20 at 19 middle parts in hydraulic pressure storehouse to make cavity inner space diminish, make the jet head 15 blowout that the inside air set up through jet-propelled dish 10 lower extreme, thereby get rid of the dust on governing valve surface, avoid the dust to pile up and make the emergence rotten.
When the flexible tube 20 expands outwards, the hydraulic chamber 19 pushes the internal piston plate 21 to move downwards, so as to push the hydraulic push rod 22 with one end fixed with the piston plate 21 to move downwards, thereby driving the blocking head 31 arranged at the other end of the hydraulic push rod 22 to move downwards, so that the communicating channel 44 is communicated with the liquid inlet pipe 13 and the liquid discharge pipe 14, so that the liquid can flow smoothly after being filtered by the filter plate 42, and when the liquid flows into the communicating channel 44, the blocking head 31 is pushed upwards, so that the hydraulic push rod 22 moves upwards, but due to the existence of the liquid in the hydraulic chamber 19, the hydraulic push rod 22 can move back and forth between two forces, and due to the first spring 11 arranged outside the hydraulic push rod 22, the movement amount can be balanced to some extent, thereby achieving the purpose of controlling the liquid flow amount.
In the process of the hydraulic push rod 22 moving back and forth, the flexible expansion plate 37 arranged at the bottom of the blocking block rotates along the rotating shaft 36 in the process of moving back and forth, so that the flexible expansion plate is continuously expanded outwards and then contracted, and the polishing block 39 outside the flexible expansion plate 37 is continuously polished to clean the inner wall of the cavity in the expansion and retraction process, so that the inside sludge can be cleaned in time. In this connection, the liquid will also drive the expanding bottom plate 35 to rotate, so as to drive the flexible expanding plate 37 to rotate, and because the amount of the liquid flowing through is not fixed, the rotating speed and the lifting speed will be changed, thereby achieving the multi-angle cleaning of the inner wall.
If hydraulic rod 22 moves down when the distance is too big, just can make the contact bar 38 of extension bottom plate 35 bottom to come into contact with cavity inner wall, thereby will extend bottom plate 35 and remove in to extension cavity 28, thereby accomplish to draw in flexible expansion board 37 inward shifting through the horn mouth 32 that extension cavity 28 top set up afterwards, and after hydraulic rod 22 lifted up, the second spring 29 who sets up in extension cavity 28 just can outwards be pushed out again with objects such as extension bottom plate 35, thereby continues to carry out inside clearance.
