As an implementation manner of the present invention, a plurality of hard brushes 20 are uniformly arranged on the outer wall of the fixing rod 9 located at the outermost ring of the pushing plate 8, the top end of the fixing rod 9 is connected to a metal swing rod 21 through an elastic hose 91, the hard brushes 20 are uniformly arranged on the outer wall of the metal swing rod 21, the top end of the metal swing rod 21 and the bottom end surface of the limiting piston 10 are always in a non-contact state, the metal swing rod 21 can be bent and suspended at the inner wall position of the electromagnetic soft ring 19 through electromagnetic absorption of the electromagnetic soft ring 19, and the hard brushes 20 are arranged between the bent metal swing rod 21 and the inner wall of the electromagnetic soft ring 19; when the electromagnetic soft ring cleaning device works, when the limiting piston 10 needs to move upwards, the controller controls the electromagnetic soft ring 19 to lose power, so that the electromagnetic soft ring 19 loses magnetism, at the moment, the limiting piston 10 moves upwards under the upward driving force of the limiting pipe 6, so that the limiting piston 10 is separated from the electromagnetic soft ring 19, the upward movement of the driving plate 8 inevitably drives the fixing rods 9 on the outer ring to move upwards, when the elastic hose 91 arranged at the top end of the fixing rod 9 moves to the bottom end position of the inner ring of the electromagnetic soft ring 19, the metal swing rod 21 is aligned with the inner ring wall of the electromagnetic soft ring 19, at the moment, the digital control center controls the electromagnetic soft ring 19 to be powered on, so that the electromagnetic soft ring 19 has certain magnetism, further, the electromagnetic soft ring 19 can bend the connection part of the metal swing rod 21 and the fixing rod 9 by the magnetic adsorption force generated by the metal swing rod 21, so that the brush 20 arranged on the inner wall of the metal swing rod 21 can rotate and clean the inner ring wall of the electromagnetic soft ring 19, effectively prevent that the incrustation scale that bonds on the soft ring 19 inner wall of electromagnetism is too much, and thickness is different, lead to being connected the phenomenon that the leakproofness reduces between spacing piston 10 and the soft ring 19 of electromagnetism, and then influence the stable normal use of intelligent hydrovalve, the stereoplasm brush 20 that sets up on the dead lever 9 inner wall simultaneously can rotate the clearance to inlet tube 2, the incrustation scale on the inside wall of outlet pipe 3 and the second intercommunication chamber 13 linking department strikes off, effectively prevent linking the incrustation scale that the department bonds too much, and then influence the phenomenon of the effective clearance of dead lever 9.
As an embodiment of the present invention, one side of the water inlet pipe 2 and one side of the water outlet pipe 3 away from the bottom of the second communicating cavity 13 are both provided with a sealing rubber ring; during operation, the sealing performance of the hydraulic valve body can be improved through the arrangement of the sealing rubber ring.
The working principle is as follows: firstly, water is extruded into the hydraulic valve body 1 through the water inlet pipe 2, it should be noted that the water pressure detector 18 is in signal connection with the digital control center, the water pressure detector 18 can transmit the water pressure inside the hydraulic valve body 1 to the digital control center through signals, so that a detection person can detect the water pressure condition inside the hydraulic valve body 1 in time, the water flow entering into the hydraulic valve body 1 through the water inlet pipe 2 pushes the pushing block 16 through the first communicating cavity 4, thereby driving the pushing block 16 to move upwards under the action of the water flow pushing force, further driving the pushing rod 5 fixedly connected with the top of the pushing block 16 to move upwards, in the process of moving the pushing rod 5 upwards, the top of the pushing rod 5 pushes the limiting piston 10, thereby driving the limiting piston 10 to move upwards, at this time, the limiting piston 10 does not block the communication position between the water inlet pipe 2 and the water outlet pipe 3 any more, therefore, water flows out of the hydraulic valve body 1 through the water outlet pipe 3, because the pushing plate 8 is positioned at the upper end of the right side inside the water inlet pipe 2, when the water flows, the pushing force of the water to the pushing plate 8 is greater than the extrusion force of the water to the pushing plate 8, so that the pushing plate 8 starts to move upwards, the impact force of the water to the inner side wall of the joint of the water inlet pipe 2, the water outlet pipe 3 and the second communicating cavity 13 is improved, meanwhile, because the periphery of the pushing plate 8 is fixedly connected with the spiral fan blades 17 and the pushing plate 8 is movably connected with the limiting pipe 6, therefore, the spiral fan blades 17 drive the pushing plate 8 to rotate under the action of the water flow, thereby promoting the fixed rod 9 fixedly connected with the pushing plate 8 to scrape off scale on the inner side wall of the joint of the water inlet pipe 2, the water outlet pipe 3 and the second communicating cavity 13, thereby effectively avoiding the scale from causing the blockage of the hydraulic valve, and simultaneously, under the action of the pushing force of the pushing plate 8, can strengthen the impact force of slurcam 8 to water, thereby further strengthen the clearance of dead lever 9 to the inside incrustation scale of hydrovalve, meanwhile, at the in-process that slurcam 8 moved upwards, slurcam 8 can drive extrusion block 11 of dead lever 9 on to spacing piston 10 and extrude, thereby it removes extrusion block 11 and spacing piston 10's linking department from spacing piston 10's inside to drive through-hole 12 on the extrusion block 11, thereby extrusion block 11 can lubricate spring 14 with the inside lubricating oil that spacing piston 10 is inside to second intercommunication chamber 13, the phenomenon of avoiding spring 14 elasticity to reduce takes place.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
