[0002] A wedge valve is an opening and closing device used to connect or cut off the medium in a pipeline. It is widely used in oil and steam pipelines in petrochemicals, thermal power plants, etc. The valve plate of a wedge valve is usually cylindrical, and the two end faces of the cylinder are at a certain angle to the vertical center line of the valve body. In order to ensure the sealing effect of the valve, the valve usually needs to be inspected and maintained regularly.
