Description

Technical Field

[0001] The utility model relates to the technical field of electric butterfly valves, in particular to a high-strength housing of an electric butterfly valve. Background Art

[0002] The electric butterfly valve is a valve that uses a circular butterfly plate as a start and stop part and rotates with the valve stem to open, close and adjust the fluid channel. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When it rotates to 90°, the valve is fully open.

At the same time, a single rotation drives the internal valve plate to flip and control the operation. When the valve plate is set inside the shell to form a specified angle, it will form a resistance force on the electric equipment under the impact force, which will seriously damage the electric equipment and make it unusable.
