[0002] A butterfly valve, also known as a flap valve, is a regulating valve with a simple structure. It can be used for on-off control of low-pressure pipeline media. A butterfly valve refers to a valve whose closing member (valve disc or butterfly plate) is a disc, which 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 cutting and throttling role in the pipeline. The butterfly valve opening and closing member is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening, closing or regulation.

[0003] Most of the existing handle butterfly valves limit the position of the handle by connecting a limit column and a limit hole to prevent people from accidentally touching and turning the handle to open or close the valve. However, this method cannot fix the limit column, and there is still a risk of people accidentally touching the limit column to lift the limit column and turn the handle. In addition, the distance between the limit holes is too large, and it is impossible to achieve precise control of the flow of the butterfly valve. After searching, it was found that the technical solution provided by the utility model with application number CN202220608652.3 also has the above-mentioned problems. Utility Model Content
