Pressure distribution measuring device for cavity sidewall and valve core wall surface of hydraulic cone valve

Provided is a pressure distribution measuring device for the cavity sidewall and the valve core wall surface of a hydraulic cone valve. A valve sleeve is arranged in a valve body. The valve sleeve is fixed in the valve body through a valve sleeve cover plate. A valve core is fastened to the valve body through a screw. The valve sleeve is provided with four valve sleeve pressure measuring hole sets which are circumferentially distributed along the valve sleeve in an equally spaced mode. The projections, on the axis, of twelve small pressure measuring holes are distributed evenly. Six pressure drawing holes with the projections being evenly distributed on the axis are correspondingly formed. The valve sleeve is rotated, and pressure distribution of the valve core bottom and the valve cavity sidewall of the cone valve is measured through the device by adopting a test method.
