The invention discloses an elastic compression device provided with a scaleplate. The elastic compression device comprises a contraction cover, a spring and a connecting shaft. The lower end of the connecting shaft stretches into the contraction cover, and the connecting shaft can axially move in the contraction cover and is a step shaft. The connecting shaft is sleeved with the spring. The lowerend of the spring abuts against the upper end of the contraction cover, and the upper end of the spring abuts against the lower bottom face of the step at the upper portion of the connecting shaft. The connecting shaft and the contraction cover are sleeved with an adjusting sleeve. The upper portion of the adjusting sleeve is in threaded connection with the outer surface of the step of the connecting shaft, the lower portion of the adjusting sleeve and the contraction cover are connected and limited through clamping columns, and a scale is arranged on the outer wall of the adjusting sleeve. The labor intensity of workers is greatly relieved, and cost is greatly reduced; and the beneficial effects that the concept is ingenious, the structure is simple, implementation is easy, and reliability is good are achieved.
Description
technical field [0001] The invention relates to an elastic compression device equipped with a ruler. Background technique [0002] Ball valves are widely used in industries such as petroleum, chemical industry and urban central heating. When conveying high temperature (> 280°C) or medium with tiny particles, hard-sealed ball valves are generally selected. To ensure good sealing of the hard-sealed ball valve, it depends on the roundness and roughness of the spherical surface of the ball. The sphere grinders available in the domestic market are basically suitable for the processing of spheres with diameters below 250mm. If you want to increase the diameter, the price will be more expensive. Imported ball mills are expensive and require high maintenance costs. If the traditional manual grinding method is adopted, the production efficiency is low and the operation labor intensity is relatively high. In order to meet the processing requirements of <400mm spherical surfa...
