[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 5 The utility model proposes a ball valve which is convenient for cleaning dirt, comprising a valve body 1, a water inlet 2 being provided at one end of the valve body 1, a water outlet 3 being provided at the other end of the valve body 1, a valve ball 4 being provided inside the valve body 1, a rotating shaft 2 5 being fixedly connected to the outer wall of the valve ball 4, the rotating shaft 2 5 passing through the valve body 1 and being rotatably connected to the valve body 1, the valve body 1 being passed through by a sewage pipe 11 and being fixedly connected to the sewage pipe 11, a sealing cover 14 being threadedly connected to the sewage pipe 11, a water stop block 15 being slidably connected to the inner wall of the sealing cover 14, the water stop block 15 and the sewage pipe 11 being matched with each other, and the material of the water stop block 15 is rubber, which is used to improve the sealing performance of the valve body 1.

[0030] Furthermore, a spring 16 is fixedly connected to the outer wall of the water stop block 15, and one end of the spring 16 away from the water stop block 15 is fixedly connected to the inner wall of the sealing cover 14. When the sealing cover 14 is twisted, the sewage pipe 11 will squeeze the water stop block 15, causing the water stop block 15 to move downward, and at the same time, the spring 16 will undergo elastic deformation. When the sealing cover 14 is installed, the spring 16 will apply a force to the water stop block 15, causing the water stop block 15 to fit tightly against the outer wall of the sewage pipe 11, thereby further improving the sealing performance of the valve body 1. A water stop plate 12 is provided in the valve body 1. The outer wall of the plate 12 is fixedly connected with a rotating shaft 13, which passes through the valve body 1 and is rotatably connected to the valve body 1. The outer wall of the rotating shaft 13 is rotatably connected with a cross bar 51, and the end of the cross bar 51 away from the rotating shaft 13 is rotatably connected to the outer wall of the rotating shaft 2 5; when the rotating shaft 2 5 rotates ninety degrees, the cross bar 51 will exert a force on the rotating shaft 13, so that the rotating shaft 13 rotates synchronously. When the rotating shaft 13 rotates, the water stop plate 12 will rotate synchronously, thereby intercepting the flow at the sewage pipe 11, thereby preventing a large amount of water in the valve body 1 from flowing out when the sealing cover 14 is removed.

[0031] In the embodiment of the utility model, in order to clean the inside of the valve body 1, a cleaning device 6 is provided between the valve ball 4 and the water inlet 2, and the cleaning device 6 comprises a filter screen 61, the filter screen 61 is fixedly connected to the inner wall of the valve body 1, a transverse axis 62, the transverse axis 62 penetrates the filter screen 61 and is rotatably connected to the filter screen 61, an impeller 63, the impeller 63 is fixedly connected to the outer wall of the transverse axis 62, a scraper 64, the scraper 64 is fixedly connected to the outer wall of the transverse axis 62, a cleaning rod 65 is penetrated by the transverse axis 62 and is fixedly connected to the outer wall of the transverse axis 62, the cleaning rod 65 is slidably connected to a cleaning block 66, the outer wall of the cleaning block 66 is fixedly connected to a second spring 67, and one end of the second spring 67 away from the cleaning block 66 is fixedly connected to the inner wall of the cleaning rod 65;

[0032] When water flows inside the valve body 1, the impeller 63 rotates under the action of the water flow. During this process, the scraper 64 and the cleaning rod 65 fixedly connected to the horizontal shaft 62 rotate. The scraper 64 rotates on the outer wall of the filter screen 61, so that impurities on the outer wall of the filter screen 61 can be cleaned. At the same time, when the cleaning rod 65 moves, Figure 4 As shown in , at this time, the filter screen 61 will apply a force to the cleaning block 66, causing the cleaning block 66 to slide into the inside of the cleaning rod 65, and at the same time, the spring 2 67 will undergo elastic deformation. When the cleaning block 66 completely enters the inside of the cleaning rod 65, the cleaning rod 65 starts to rotate. During this process, when the cleaning block 66 coincides with the filter hole, the cleaning block 66 will bounce into the filter hole under the elastic force of the spring 2 67, thereby cleaning the filter hole and preventing the filter screen 61 from being blocked.

[0033] In the utility model, during use, when water flows inside the valve body 1, the impeller 63 rotates under the action of the water flow. During this process, the scraper 64 and the cleaning rod 65 rotate to clean the filter 61. Then, the rotating shaft 2 5 is rotated to rotate the valve ball 4 ninety degrees. At the same time, under the transmission of the cross bar 51, the rotating shaft 13 will drive the water stop plate 12 to rotate, thereby closing the valve body 1. Then, the sealing cover 14 is unscrewed. At this time, the impurities cleaned out will be discharged together with the residual water in the valve body 1.
