Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valves, in particular to a butterfly valve capable of preventing a sealing rubber ring from deflecting. Background Art

[0002] Butterfly valve, also called flap valve, is a simple regulating valve that can be used for the on-off control of low-pressure pipeline media. 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 the role of cutting off and throttling in pipelines.

[0003] After searching, the existing Chinese patent announcement number is: CN220227863U, which provides a butterfly valve that prevents the sealing rubber ring from shifting. The patent makes the handle easy to install and disassemble by setting a groove, a second threaded groove and a second threaded column. When the valve plate needs to be rotated, the upper end of the first movable rod is inserted into the groove. When the handle needs to be used frequently for a long time, the second threaded column is screwed so that one end of the second threaded column passes through the second through groove and enters the second threaded groove to strengthen the connection between the handle and the first movable rod. When the state of the butterfly valve does not need to be changed frequently, in order to prevent non-related personnel from mistakenly controlling the butterfly valve, the second threaded column is screwed and the handle is removed. The easy-to-install and disassemble handle makes the operation of the valve safer.
