Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-10This utility model provides a technical solution: an automatic sewage discharge electric ball valve, including a valve body 1, a spherical groove 2 provided inside the valve body 1, a ball valve 3 rotatably disposed inside the spherical groove 2, a first through hole 4 communicating with the spherical groove 2 through the valve body 1, a second through hole 5 communicating with the first through hole 4 on the ball valve 3, a protective cover 6 fixedly connected to the upper surface of the valve body 1, a rotating motor 7 fixedly connected to the inner upper surface of the protective cover 6, and a rotating shaft 8 fixedly connected to the output end of the rotating motor 7. A connecting rod 9 is fixedly connected to one end of shaft 8. One end of the connecting rod 9 extends into the spherical groove 2 through a sealed bearing 10 and is fixedly connected to the spherical valve 3. A water inlet pipe 11 communicating with the first through hole 4 is fixedly connected to the left side of the valve body 1. A water outlet pipe 12 communicating with the first through hole 4 is fixedly connected to the right side of the valve body 1. A fixed housing 13 is fixedly connected to the front surface of the valve body 1. A controller 14 and a timer 15 are fixedly connected to the front surface of the valve body 1 and located inside the fixed housing 13. The valve body 1 and the spherical groove 2 are connected to the spherical valve 3. The system comprises a ball valve 3, a first through hole 4, a second through hole 5, a protective cover 6, a rotating motor 7, a rotating shaft 8, a connecting rod 9, a sealed bearing 10, a controller 14, and a timer 15. The timer 15 sets a timer for the drain valve. When the drain time is reached, the controller 14 operates the rotating motor 7. The output of the rotating motor 7 drives the rotating shaft 8 to rotate, which in turn causes the ball valve 3 to rotate within the spherical groove 2 via the connecting rod 9. This connects the first through hole 4 and the second through hole 5, creating a passage. After the drain time ends, the rotating motor 7 can drive... The ball valve 3 rotates again, causing the first through hole 4 and the second through hole 5 to be misaligned and form a circuit. This drain valve has an automatic timed drain function, avoiding the disadvantages of manual timed operation, making the drain valve more reliable and practical. The front surface of the fixed housing 13 is hinged with a cover plate 16. The fixed housing 13 and the cover plate 16 can protect the controller 14 and the timer 15. When the controller 14 needs to be operated, the cover plate 16 can be opened. The water inlet pipe 11 is equipped with a filter mechanism.

[0029] A first connecting plate 17 is fixedly connected to the right side of the cover plate 16. A second connecting plate 18 is fixedly connected to the right side of the fixed housing 13 at a position corresponding to the first connecting plate 17. A plug-in plate 19 is fixedly connected to the rear surface of the first connecting plate 17. A plug-in groove 20 for the plug-in plate 19 to be inserted is provided on the front surface of the second connecting plate 18. A first cavity 21 is provided at both the upper and lower positions inside the second connecting plate 18. A movable plate 22 is slidably disposed in the first cavity 21. A threaded rod 24 is rotatably connected to one side of the movable plate 22 through a bearing 23.

The screwing plate 25 drives the threaded rod 24 to rotate. The threaded rod 24 is threadedly connected to the second connecting plate 18. The rotation of the threaded rod 24 causes the movable plate 22 to move under the cooperation of the bearing 23, the limiting block 28 and the limiting groove 29. Then, through the cooperation of the fixing rod 26 and the fixing hole 27 on the plug-in plate 19, the plug-in plate 19 can be fixed, thereby fixing the housing 13 and the cover plate 16.

[0030] The cover plate 16 is provided with an observation window 30, through which the controller 14 and the timer 15 can be observed;

[0031] The filtration mechanism includes a filter housing 31, which is fixedly connected to the water inlet pipe 11. The filter housing 31 has an opening 32 communicating with the water inlet pipe 11. A fixing plate 33 is fixedly connected to the upper surface of the filter housing 31. The fixing plate 33 has a slot 34, in which a placement plate 35 is placed. A connecting block 36 is fixedly connected to the lower surface of the placement plate 35. The upper surface of the filter housing 31 has an opening 37 for the connecting block 36 to pass through. A filter screen 38 is fixedly connected to the lower surface of the connecting block 36. The filter screen 38 slides against the filter housing 31. The upper surface of the placement plate 35 is fixedly connected to a handle 39. A second cavity 40 is provided at both the left and right positions within the fixed plate 33. A limiting mechanism is provided within the second cavity 40 to limit the position of the placement plate 35. Through the setting of the filtering mechanism, the filter screen 38 can filter impurities, preventing impurities from clogging the drain valve, causing damage to the drain valve, and increasing economic costs. The limiting mechanism enables the fixing and disassembly of the placement plate 35, thus facilitating the removal and insertion of the filter screen 38. After a period of use, the filter screen 38 can be removed for cleaning, which is quite convenient.

[0032] The limiting mechanism includes a sliding plate 41, which is slidably disposed within a second cavity 40. Multiple springs 42 are fixedly connected to the inner wall of the second cavity 40, with one end of each spring 42 fixedly connected to the sliding plate 41. Multiple limiting rods 43 are fixedly connected to one side of the sliding plate 41, with one end of each limiting rod 43 extending into a slot 34. The placement plate 35 has limiting holes 44 for the limiting rods 43 to be inserted into. Multiple sliding rods 45 are fixedly connected to the upper surface of the sliding plate 41, with one end of each sliding rod 45 extending out of a fixed plate 33 and jointly fixedly connected to a pull plate 46. The upper surface of 3 is provided with a sliding groove 47 for the sliding rod 45 to move. With the setting of the limiting mechanism, the pull plate 46 can be pulled during use. The pull plate 46 drives the sliding plate 41 to move in the second cavity 40 through the sliding rod 45. At this time, the spring 42 contracts and generates elastic deformation. The movement of the sliding plate 41 causes the limiting rod 43 to retract. The limiting rod 43 disengages from the limiting hole 44 on the placement plate 35, thereby releasing the limitation on the placement plate 35 and making it convenient to take out the filter screen 38. Similarly, after the pull plate 46 is released, the spring 42 restores its elastic deformation, allowing the limiting rod 43 to be inserted into the limiting hole 44, thereby realizing the limitation and fixation of the placement plate 35.

[0033] A sealing ring 48 is fixedly connected to the lower surface of the placement plate 35, and a sealing groove 49 is provided on the upper surface of the filter housing 31 to cooperate with the sealing ring 48. The sealing performance of the connection of the placement plate 35 is achieved by setting the sealing ring 48 and the sealing groove 49.

[0034] One end of the inlet pipe 11 and the outlet pipe 12 are fixedly connected to a flange 50. The flange 50 is provided with multiple connection holes 51. Through the setting of the flange 50 and the connection holes 51, the drain valve can be installed.

[0035] Working Principle: In use, this invention utilizes the coordination between the valve body 1, spherical groove 2, ball valve 3, first through hole 4, second through hole 5, protective cover 6, rotating motor 7, rotating shaft 8, connecting rod 9, sealed bearing 10, controller 14, and timer 15. Timer 15 sets the time for the drain valve. When the drain time is reached, controller 14 controls rotating motor 7, whose output drives rotating shaft 8. This, in turn, causes ball valve 3 to rotate within spherical groove 2 via connecting rod 9, connecting the first through hole 4 and the second through hole 5 to form a passage. After the drain time ends, rotating motor 7 drives the ball valve 3 to rotate within spherical groove 2. Valve 3 rotates again, causing the first through hole 4 and the second through hole 5 to be misaligned and form a circuit break. This drain valve has an automatic timed drain function, avoiding the disadvantages of manual timed operation, making the drain valve more reliable and practical. Through the setting of the filter mechanism, the filter screen 38 can filter impurities, preventing impurities from clogging the drain valve, causing damage to the drain valve, and increasing economic costs. The setting of the limit mechanism can realize the fixing and disassembly of the placement plate 35, which facilitates the removal and placement of the filter screen 38. After a period of use, the filter screen 38 can be removed for cleaning, which is more convenient.
