Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valve processing, in particular to a butterfly valve stem positioning device. 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] 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 adjustment. When assembling the butterfly valve, the valve stem needs to be inserted into the valve body. During the assembly of the valve stem, due to the different volumes of the valve body, the valve stem is prone to deviation when inserted, causing valve stem wear and affecting subsequent use. For this reason, we propose a butterfly valve stem positioning device. Utility Model Content
