Description

Technical Field

[0001] This utility model belongs to the field of electric butterfly valve technology, and in particular relates to an electric gas butterfly valve. Background Technology

[0002] An electric butterfly valve is a type of valve that uses a circular butterfly plate as the opening and closing element, which rotates with the valve stem to open, close, and regulate the fluid passage. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline.

[0003] Currently available electric butterfly valves have the following problems when used:

[0004] 1. Traditional electric butterfly valves can generally only be installed at pipe connections via flanges. Because electric butterfly valves have many operating components installed on top, they are quite heavy and can easily loosen after prolonged use, resulting in poor connection between the butterfly valve and the pipe.

[0005] 2. Traditional electric butterfly valves typically seal directly between the valve and the gasket on the side of the pipeline. Over time, this gasket can age and deform, leading to gas leaks and resulting in poor sealing performance. Utility Model Content
