| description | The utility model belongs to the field of non-return butterfly valves, particularly relates to a non-return butterfly valve, and provides the following scheme aiming at the problem that the existing non-return butterfly valve is easy to loosen and cannot be sealed: the non-return butterfly valve comprises a butterfly valve shell and a sealing baffle plate which is positioned in the butterfly valve shell and is used for sealing, the left side of the sealing baffle is fixedly connected with a gearbox used for rotating the sealing baffle, the gearbox is fixedly connected with the surface of the butterfly valve shell, and the top of the gearbox is fixedly connected with a rotating handle used for rotating the gearbox. By arranging the butterfly valve shell, the sealing baffle, the gearbox, the rotating handle, the fixing column, the adjusting structure and the limiting and fixing structure, the rotating handle can drive the sealing baffle to rotate through the gearbox by rotating the rotating handle, the effect o |
