Since the cylinder has a stroke when it is in action, the specific working range determines the size of the butterfly valve, which is generally much larger than the pipeline. This highlights that butterfly valves are not suitable for certain small ships and the space utilization rate is not high during installation.

[0003] In the prior art, a patent with publication number CN219994505U discloses a butterfly valve that is easy to install, including a pneumatic butterfly valve and a connecting pipe body, wherein the lower end of the pneumatic butterfly valve is connected to a valve body plate for closing or opening, and the lower end of the pneumatic butterfly valve is located on the outer side of the valve body plate and is connected and fixed with a valve steel ring, and the two connecting pipe bodies are respectively connected to the left and right sides of the valve steel ring, and the left and right sides of the valve steel ring are fixed with a plurality of reinforcing steel plates distributed along the circumferential direction, and positioning holes are opened on the reinforcing steel plates.

[0004] The above structure enables the butterfly valve and the pipe body to be better fixed and connected using fastening bolts. However, in some small ships, the installation space is small and it is impossible to ensure the horizontal installation of the butterfly valve before connecting the butterfly valve and the pipe body. As a result, during the connection process of the butterfly valve and the pipe body, there is a risk of the medium in the pipeline leaking from the valve stem, and the angle during installation cannot be adjusted.
