[0011] 1. In the utility model, the support ring, spring and sealing ring are pressed against the surface of the ball valve to generate an inward pressure around the ball valve. Compared with the lateral force generated by the disc spring on the ball valve before, the ball valve is more completely closed to avoid wear of the sealing ring caused by long-term rotation.

[0012] 2. In the utility model, the water flow speed is measured by a water flow speed meter, and the valve stem is controlled by a motor to drive the ball valve to rotate, so as to realize the opening and closing of the channel and the size of the water flow speed. Compared with the previous manual adjustment, the water flow speed can be adjusted according to different requirements.

[0021] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0022] Reference Figure 1-4 , the utility model embodiment is an automatic regulating valve disc, which includes a valve body 1, a display 2 and a valve cover 3. The valve body 1 is cylindrical, and a fixed block 7 is fixedly connected in the middle of the valve body 1. A buffer pad 9 is fixedly connected to the other side of the fixed block 7. A support ring 8 is fixedly connected in the buffer pad 9. A sealing ring 10 is fixedly connected to the other end of the support ring 8. A filter screen 13 is fixedly connected to the middle channel of the support ring 8. The sealing ring 10 is made of waterproof elastic rubber material and has good ductility and corrosion resistance. A filter screen 13 is fixedly connected in the middle channel of the support ring 8. The filter screen 13 can filter some impurities in the water body.
