[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] like Figures 1-3 As shown, this embodiment proposes an electric valve with adjustable flow rate, including an electric valve body 1. A motor 2 is fixedly connected to the top of the electric valve body 1. An adjusting plate descaling assembly 3 is provided inside the electric valve body 1. The adjusting plate descaling assembly 3 includes an adjusting plate 31. The top of the adjusting plate 31 is fixedly connected to the output shaft of the motor 2. A crossbar 32 is fixedly connected to the side of the adjusting plate 31. A pressing block 33 is fixedly connected to the side of the crossbar 32. A slot 34 is opened on the inner wall of the electric valve body 1. A triangular block 35 is slidably connected to the inner wall of the slot 34. A vertical rod 37 is fixedly connected to the bottom of the triangular block 35. An inclined rod 38 is fixedly connected to the side of the vertical rod 37. A scraper plate 39 is fixedly connected to the end of the inclined rod 38 away from the vertical rod 37. A spring telescopic rod 36 is fixedly connected to the bottom of the triangular block 35.

[0027] The triangular block 35 is located on the displacement trajectory of the extrusion block 33. The end of the spring telescopic rod 36 away from the triangular block 35 is fixedly connected to the inner wall of the slot 34. The design of the spring telescopic rod 36 is beneficial to the automatic reset of the triangular block 35 by the elastic force of the spring telescopic rod 36 when the triangular block 35 is not being extruded.

[0028] Several diagonal bars 38 and scraper plates 39 are provided and are arranged in a linear array on the side of the vertical bar 37. The adjusting plate 31 is located on the displacement trajectory of the scraper plate 39. The adjusting plate 31 is located on the displacement trajectory of the scraper plate 39, which is beneficial to scrape the outer wall of the adjusting plate 31 when the scraper plate 39 moves up and down, thereby removing the scale on the adjusting plate 31.

[0029] The side of the extrusion block 33 close to the triangular block 35 is provided with an inclined surface, and the side surface of the electric valve body 1 is provided with a water outlet 5. When the extrusion block 33 moves, the triangular block 35 can be extruded to move downward through the inclined surface of the extrusion block 33.

[0030] In this embodiment, the electric valve is used for sewage discharge control. The motor 2 drives the adjusting plate 31 to rotate, so as to adjust the size of the opening of the adjusting plate 31 on the inner wall of the electric valve body 1, thereby controlling the flow of sewage discharge. Therefore, when adjusting the flow, the adjusting plate 31 may contact the dirt on the sewage. Over a long period of time, the scale attached to the adjusting plate 31 may affect the control of the sewage flow by the adjusting plate 31. Therefore, in this application, the cross rod 32 is provided. When the motor 2 rotates clockwise, the adjusting plate 31 rotates clockwise, opens the valve port, and allows the sewage to flow through the gap, so as to allow the sewage to flow. The clockwise rotation of the adjusting plate 31 drives the cross rod 32 and the extrusion block 33 to rotate. The triangular block 35 is located on the movement track of the extrusion block 33. When the extrusion block 33 rotates, it extrudes the triangular block 35. The extrusion block 33 is provided with an inclined surface, and the triangular block 35 is also provided with an inclined surface. When the extrusion block 33 extrudes the triangular block 35, the triangular block 35 is extruded to move downward. The downward movement of the triangular block 35 extrudes the spring telescopic rod 36, and drives the vertical rod 37 and the inclined rod 38 to move downward. The downward movement of the inclined rod 38 drives the scraping plate 39 to move downward. The scraping plate 39 is located on the side of the adjusting plate 31. When the scraping plate 39 moves downward, it can scrape the surface of the adjusting plate 31. When the electric valve does not need to continue to discharge sewage, the motor 2 can be driven to rotate counterclockwise, which drives the cross rod 32 and the extrusion block 33 to rotate counterclockwise, so that the extrusion block 33 will not continue to extrude the triangular block 35. The triangular block 35 will automatically reset through the spring telescopic rod 36. When the triangular block 35 resets, it moves upward, so that the vertical rod 37, the inclined rod 38 and the scraping plate 39 move upward, which will scrape the outer wall of the adjusting plate 31 again, thereby reducing the scale on the outer wall of the adjusting plate 31. The adjusting plate 31 close to the scraping plate 39 is close to the water outlet 5, which can clean this side of the adjusting plate 31, and can also reduce the resistance during sewage discharge. Through the fine adjustment of the adjusting plate 31, the discharge amount of the sewage can be controlled very accurately, which avoids the system efficiency problem caused by too large or too small flow. Through the automatic cleaning mechanism of the scraping plate 39, the scale or scale on the adjusting plate 31 can be removed regularly, which effectively maintains the long-term normal operation of the valve. This not only reduces the cost and frequency of manual maintenance, but also ensures the flow control accuracy of the valve. The surface of the cleaned adjusting plate 31 can significantly reduce the resistance during sewage discharge, so as to ensure that the sewage flows more smoothly. The cleaning effect is of great significance to maintain the high efficiency of the system and prevent the sewage system from being unstable or blocked due to scale accumulation.

[0033] The elastic plate 45 is located on the displacement track of the touch rod 41, the adjusting plate 31 is located on the displacement track of the vibration rod 48, the water outlet 5 is located on the side of the extrusion block 33, the elastic plate 45 is located on the displacement track of the touch rod 41, which is beneficial to extruding the elastic plate 45 when the touch rod 41 moves.

[0034] The spring 46 is provided with two, and is linearly arrayed on the side of the rectangular plate 43, the vibration rod 48 is provided in a circular plate shape, the rectangular plate 43 is located on the side of the adjusting plate 31, and the design of the spring 46 is beneficial to automatically returning to the original position through the elastic force of the spring 46 when the elastic plate 45 is not extruded.

[0036] In this embodiment, when the adjusting plate 31 rotates clockwise, the touch rod 41 will be pressed to the elastic plate 45, moving the elastic plate 45 to the side close to the rectangular plate 43, and driving the vibration rod 48 to move to the side close to the rectangular plate 43. When the adjusting plate 31 rotates counterclockwise, the touch rod 41 will rotate counterclockwise, so the touch rod 41 will not continue to press the elastic plate 45, and the elastic plate 45 will not be pressed, and the elastic plate 45 can be automatically reset by the spring 46. When the elastic plate 45 is automatically reset, it will drive the connecting rod 47 and the vibration rod 48 to be automatically reset. The vibration rod 48 is located on the side of the adjusting plate 31, and the adjusting plate 31 is located on the displacement track of the vibration rod 48. The vibration rod 48 will impact the adjusting plate 31, and knock the side of the adjusting plate 31 close to the water inlet 6, thereby reducing the scale on this side of the adjusting plate 31. Through the interaction between the adjusting plate 31 and the vibration rod 48, the accumulation of scale near the adjusting plate 31 can be effectively reduced, ensuring that the flow regulation of the electric valve is more accurate and stable. The reduction of scale helps to avoid the instability of flow or valve failure caused by scale blockage of the valve, thereby prolonging the service life of the equipment and improving its performance. Through the fine adjustment of flow and the automatic cleaning mechanism, the electric valve can maintain high-efficiency operation in long-term use.
