Specifically, the method comprises the following steps: the cleaning process of the cleaning assembly is divided into the following cases:
referring first to fig. 7, at this time, the valve plate 409 is in sealing contact with the outlet 103, and the flow chamber 101 is filled with liquid;
secondly, referring to fig. 8, at this time, the outlet 103 is opened, the valve plate 409 moves upwards, the liquid flowing in the flow cavity 101 extrudes the stress plate 504, and the stress plate 504 generates a transverse thrust after being stressed, so that the rack plate 502 is driven to move transversely, the transmission gear 501 rotates, and the other rack plate 502 is driven to move transversely, so that the two rack plates 502 are gathered in opposite directions, and therefore, in the process of moving the valve plate 409 upwards, the cleaning sleeve 503 is not always abutted against the inner walls of the outlet 103 and the valve body 1, so that the dirt such as silt in the liquid can be discharged normally;
referring to fig. 9, at this time, the valve plate 409 moves to the uppermost position of the flow chamber 101, and the valve plate 409 does not move downward until the liquid is discharged, so as to perform a cleaning operation;
referring to fig. 10, when the liquid is completely discharged, the valve plate 409 is ready to move downwards, and after the liquid is completely discharged, the pushing force on the force bearing plate 504 cannot be generated any more, so that under the action of the coil spring 6, the transmission gear 501 rotates and resets, and is unfolded outwards through the rack plate 502, so that the cleaning sleeve 503 is abutted against the inner wall of the valve body 1;
referring to fig. 11, at this time, the valve plate 409 moves downwards, so that in the process of moving downwards, dirt such as silt and the like remained on the inner wall of the valve body 1 can be cleaned through the cleaning sleeve 503 and finally pushed into the outlet 103 to be discharged, and the smoothness of the inner wall of the valve body 1 and the opening at the top of the outlet 103 is guaranteed;

Specifically, the method comprises the following steps: in the fourth, fifth and sixth processes, the outlet valve 405 needs to be opened at this time to remove the pressure in the hydraulic pressure chamber 403, and in the pressure releasing process, because the inner diameter of the connecting pipe 406 is much larger than the inner diameter of the inlet pipe 404, the water source accumulated in the connecting pipe 406 is larger, and the main source of the hydraulic pressure comes from the amount of water and the height of the water, which is not convenient to adjust due to the problem of construction and installation, but the water amount can be increased by increasing the inner diameter, so that the hydraulic pressure releasing cannot be completed immediately, at this time, under the action of the hydraulic pressure, the water can be ejected through the high-pressure nozzle 8, the water of the nozzle flushes the arc surface at the top of the valve plate 409, the cleaning effect is further improved, the residue of dirt is avoided, the ejected water can enhance the cleaning of the inner wall of the valve body 1, and the ejected water finally flows out from the gap between the two cleaning sleeves 503.
The valve seat 3 and the valve cover 2 are connected through screws 9, the screws 9 penetrate through the elastic diaphragm 4, the pressing ring 901 is arranged at the position where the screws 9 penetrate through the elastic diaphragm 4, and the connection stability and the connection tightness of the elastic diaphragm 4 are improved through the pressing ring 901.
The working principle is as follows: when sewage drainage is needed, water in a drainage pool enters a water pressure cavity 403 through a connecting pipe 406 and a water inlet pipe 404, under the action of water pressure, the elastic diaphragm 4 deforms upwards, so that the valve rod 408 and the valve plate 409 are driven to move upwards through the lower pressing plate 402, the outlet 103 is opened, at the moment, sewage drainage work is performed, after sewage drainage is completed, the water outlet valve 405 is opened, water in the water pressure cavity 403 is discharged, at the moment, pressure is recovered, resetting is realized under the action of the spring 407, the outlet 103 is re-closed by the valve plate 409, wherein the top surface of the valve plate 409 is arc-shaped, when sewage drainage is performed, sewage is not easily adsorbed on the top surface of the valve plate 409, so that the residue of the sewage on the valve plate 409 is reduced, the service life of the valve plate 409 is prolonged, the corrosion of the valve plate 409 caused by the long-term residue of the sewage is avoided, and a cleaning assembly on the valve plate 409 is used for cleaning the inner wall of the valve body 1, avoid the residue of filth, improve the life of valve body 1.
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.
