Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valves, in particular to a high-performance butterfly valve. Background Art

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

[0003] The existing butterfly valve is inconvenient to operate during use, has poor overall applicability, is relatively limited, and is not convenient to use.

[0004] The existing patent (publication number: CN218543331U) provides a high-performance butterfly valve. The high-performance butterfly valve has the ability to be fixed by improving and installing the fixing mechanism. In daily use, the butterfly valve will not be displaced due to the impact of external force or internal water flow, which ensures the stable use of the high-performance butterfly valve and improves the market competitiveness of the high-performance butterfly valve; the high-performance butterfly valve has improved control ability by improving and installing the control mechanism. In daily use, it can be easily twisted without the need for external tools, which facilitates the opening and closing of the high-performance butterfly valve and improves the working effect of the high-performance butterfly valve; the high-performance butterfly valve has improved filtering ability by improving and installing the filtering mechanism. In daily use, the filtering effect of the high-performance butterfly valve is guaranteed, further ensuring the stable use of the high-performance butterfly valve and improving the service life of the high-performance butterfly valve.

[0005] The technical problem with the technical solution of the utility model is that when the butterfly valve is in use, it is necessary to press the control button to push the button bolt downward. After the friction plate at the bottom contacts the mounting plate and is completely fixed, the greater friction of the friction plate is used to reduce the possibility of the knob rotating. However, this locking method cannot completely lock the knob. During long-term use, due to the influence of the use environment, such as water corrosion, metal fatigue and deformation, wear of the friction plate, etc., the friction force is reduced, so that the knob may still rotate, resulting in a poor use effect and being not conducive to use.
