Description

Technical Field

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

[0002] Valves 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. They mainly play a cutting and throttling role in pipelines. 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] The patent specification with announcement number CN208831817U discloses a self-locking butterfly valve, including a butterfly valve body, a hinged shaft fixedly connected to the middle part of the butterfly valve body, and a butterfly plate hingedly connected to the hinged shaft. The middle part of the butterfly valve body is provided with a first cylindrical cavity and a second cylindrical cavity adjacent to the first cylindrical cavity. The diameter of the second cylindrical cavity is larger than the diameter of the first cylindrical cavity. The upper part of the second cylindrical cavity is provided with a hinged shaft. The upper part of the butterfly plate is hingedly connected to the butterfly valve body through the hinged shaft. When the butterfly valve body is in a closed state, the butterfly plate fits tightly with the second cylindrical cavity, and can self-lock the valve according to gravity to prevent water from surging downward and damaging the water pump when the water pump stops accidentally.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: when the butterfly valve body is in a closed state during use of the above device, the butterfly plate fits tightly with the second cylindrical cavity, and can self-lock the valve based on gravity to prevent water from surging downward and causing damage to the water pump when the water pump stops unexpectedly. However, when the butterfly valve is used for a long time, its locking position is prone to attachment of debris, thereby affecting the normal locking. Therefore, further improvement is needed.
