Description

Technical Field

[0001] The utility model relates to the technical field of butterfly plates, in particular to a casting device for a bronze butterfly plate. Background Art

[0002] The 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. 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 the 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.

However, burrs are left during casting and need to be polished. Workers need to constantly clamp and release the brake state of the butterfly plate. The polishing process is cumbersome and inconvenient to use. Utility Model Content
