[0001] The present application relates to the technical field of butterfly valves, and in particular to a butterfly valve capable of intelligently regulating medium throttling and filtering. Background Art

[0002] The butterfly valve, also known as the flap valve, is a simple regulating valve that can be used for the on-off control of low-pressure pipeline media. The butterfly valve refers to a valve whose closing part (valve disc or butterfly plate) is a disc that rotates around the valve axis to achieve opening and closing. The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays a role of cutting off and throttling on the pipeline. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening, closing or regulating.

[0003] When ordinary butterfly valves are used, their functions are relatively simple and they do not have the functions of throttling and filtering. Therefore, we propose a butterfly valve that can intelligently adjust the throttling and filtering of the medium. Summary of the invention
