Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valves, in particular to an impact-resistant butterfly valve. 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, but it still has the following disadvantages in actual use:

[0003] At present, the existing impact-resistant butterfly valves are usually designed in an integrated manner during production, which makes it impossible to replace the internal corrosion-resistant parts. When the corrosion-resistant parts are damaged due to long-term use, the service life of the butterfly valve comes to an end, and there are certain limitations in its use; and the existing impact-resistant butterfly valves lack relevant sealing structures when in use, or the relevant sealing structures cannot be quickly and accurately positioned, which leads to leakage. There are certain limitations in its use, so it is necessary to improve an impact-resistant butterfly valve to solve the above problems. Utility Model Content
