TECHNICAL FIELD

[0001] The utility model relates to butterfly valve pressure testing machine technical field, concretely is a vertical top pressure butterfly valve pressure testing machine with good stability. BACKGROUND

[0002] With the rapid change of industrial technology, the precision in the valve manufacturing field has reached an unprecedented level, and the application of valves is gradually expanding to larger diameters and higher pressure specifications. Under this background, the traditional claw jaw butterfly valve pressure testing machine cannot reasonably meet the pressure testing requirements, so a vertical top pressure butterfly valve pressure testing machine with good stability needs to be designed.

[0003] The traditional butterfly valve pressure testing machine mostly uses claw cylinder linkage to clamp the valve to be tested. This clamping method has high cost of synchronous claw cylinder, and the radial spacing range of multiple claw cylinders is limited, which cannot effectively clamp and pressure test valves of different diameters, affecting the later pressure testing efficiency and the application range of the pressure testing machine. SUMMARY

[0004] The utility model aims at providing a vertical top pressure butterfly valve pressure testing machine with good stability, which solves the problem of the existing claw cylinder linkage pressure testing machine that cannot clamp and pressure test valves of different diameters, affecting the later pressure testing efficiency and the application range.

[0005] To achieve the above-mentioned purpose, a vertical top pressure butterfly valve pressure testing machine with good stability is provided, which comprises a hydraulic jack and a pressure testing cushion cylinder. The output end of the hydraulic jack is connected with a pressure testing blind plate. The pressure testing cushion cylinder is installed directly below the pressure testing blind plate and cooperates with it. The bottom of the pressure testing cushion cylinder is connected with a front support frame.

[0006] According to the vertical top pressure butterfly valve pressure testing machine with good stability, the two sides of the hydraulic jack are provided with mounting rods, and the bottom of the mounting rod is provided with a workbench. The top of the workbench is placed with a pressure testing cushion cylinder.

[0007] According to the vertical top pressure butterfly valve pressure testing machine with good stability, the two sides of the bottom of the pressure testing cushion cylinder are provided with guide rails, and the outside of the guide rails is slidably provided with guide grooves connected with the workbench.

[0008] Compared with the prior art, the utility model has the advantages that by realizing the replacement of the pressure testing blind plate and the pressure testing cushion cylinder, the pressure testing machine can be used for placing and pressure testing butterfly valves of different diameters in the later stage. Compared with the traditional claw cylinder linkage pressure testing, the structure design is simple and the cost is low, which is suitable for popularization and use. Finally, the front support frame can support the pressure testing cushion cylinder to prevent it from falling during detection, and improve the accuracy of later pressure testing.

[0009] The additional aspects and advantages of the present application will be given in part in the following description, some will become apparent from the following description, or will be understood through practice of the present application. BRIEF DESCRIPTION OF DRAWINGS
