[0035] What needs to be further explained is: insert the supporting frame 401 into the interior of the supporting box 301, so that the supporting frame 401 filters the water flowing from the direction of the connecting pipe 105 to the control valve body 1. When the supporting frame 401 needs to be cleaned, first remove the fixing screws 202, and then remove the cover plate 2. At this time, the elastic force of the spring 405 causes the connecting strip 404 to rise. When the connecting strip 404 rises, it drives the supporting frame 401 to rise, which facilitates the removal of the supporting frame 401 and the cleaning of the supporting frame 401.

[0036] Working principle: When a control valve for water conservancy and hydropower is used, first, a connecting pipe 105 is arranged on one side of the control valve body 1, and the flange 106 on one side of the connecting pipe 105 is connected to an external water pipe. A bearing mechanism 3 is arranged between the control valve body 1 and the connecting pipe 105, a cover plate 2 is arranged on the top of the bearing mechanism 3, and a filtering mechanism 4 is arranged inside the bearing mechanism 3. By setting the filtering mechanism 4, it is convenient to filter the water flowing from the connecting pipe 105 to the control valve body 1, so as to avoid the control valve body 1 from being blocked and difficult to repair;

[0037] When it is necessary to avoid blockage of the control valve body 1, first insert the supporting frame 401 into the interior of the supporting box 301, so that the supporting frame 401 filters the water flowing from the connecting pipe 105 to the control valve body 1. When it is necessary to clean the supporting frame 401, first remove the fixing screws 202, and then remove the cover plate 2. At this time, the elastic force of the spring 405 causes the connecting strip 404 to rise. When the connecting strip 404 rises, it drives the supporting frame 401 to rise, so that it is convenient to take out the supporting frame 401 and clean the supporting frame 401. This device facilitates avoiding blockage of the control valve body 1.
