[0031] The working principle of this V-type marine butterfly valve is as follows:
[0032] When a V-type marine butterfly valve is installed on a marine pipeline, to improve the sealing performance of the connection between the V-type marine butterfly valve and the marine pipeline during installation, an auxiliary sealing assembly 200 is installed on the valve body 100 of the V-type marine butterfly valve. This allows the air inlet pipe 210 on the auxiliary sealing assembly 200 to input high-pressure gas supplied by an air pump into the air inlet channel 220 on the valve body 100. This allows the high-pressure gas to enter each movable groove 103 from the air inlet channel 220, thereby pushing the piston 235 installed in each movable groove 103 to move horizontally along the movable groove 103. The moving rods 231 are pushed outward along the moving groove 103, which in turn pushes the abutment plate 232 outward along the connecting groove 102. This causes the rubber sealing ring 233 on the abutment plate 232 to move outward, thus providing auxiliary sealing at the connection between the butterfly valve and the pipeline, thereby improving the quality of the V-type marine butterfly valve. Furthermore, by setting an auxiliary sealing component 200 on the valve body 100 arm of the V-type marine butterfly valve, the auxiliary sealing component 200 assists in sealing the connection between the butterfly valve and the marine pipeline, thereby improving the sealing performance and practical performance of the V-type marine butterfly valve.
