The invention discloses a comprehensive checking fixture for measuring a center line-type butterfly valve body. The comprehensive checking fixture comprises a measurement body, measurement reference positioning shafts, measurement pendulum rods, a coaxial positioning slideway, measurement display dial indicators, coaxiality test bars, and measurement correction ring gauges. First, the four dial indicators are calibrated with the correction ring gauges before the measurement, so that the dial indicators are zeroed. A product to be measured is placed in a combined checking fixture. The shape tolerance and position tolerance of five parts of the workpiece can be measured at one time. The comprehensive checking fixture of the invention has the advantages of saving the detection time and eliminating the occurrence of measurement deviation of the workpiece to be measured caused by operation skill factors of the manual use of a universal measuring tool.
Description
technical field [0001] The invention proposes a comprehensive inspection tool, in particular to a combined inspection tool for processing dimensions of various parts of a centerline butterfly valve body, mutual dimensions and mutual positional relationship of the processing parts. Background technique [0002] At present, the centerline butterfly valve, as a component used to realize the on-off and flow control of the pipeline system, has been widely used in many fields such as petroleum, chemical industry, metallurgy, and hydropower. In the known butterfly valve technology, its sealing form mostly adopts a sealing structure, and the sealing material is rubber, polytetrafluoroethylene, etc. Due to the limitations of structural features, it is not suitable for industries such as high temperature resistance, high pressure resistance, corrosion resistance, and wear resistance. An existing relatively advanced butterfly valve is a triple-eccentric metal hard-sealed butterfly val...
