Embodiment Construction
[0024] This implementation is an inspection tool for the hydraulic pressure test of the container.
[0025] like figure 1 As shown, this embodiment includes an inner block cover 1, an adapter flange 2, an outer block cover 3 and a sealing ring 8, and the inner block cover 1, the transfer flange 2 and the outer block cover 3 are With the use of.
[0026] In use, the inner blocking cover 1 is located in the container flange 10 , and the notch on the inner surface of the inner blocking cover is stuck on the inner surface of the container flange 10 . The external blocking cover 3 is located on the upper surface of the adapter flange 2 . The lower surface of the transfer flange 2 is located on the upper surface of the container flange. The inner blocking cover and the adapter flange 2 are fixedly connected by long screws 4 ; the outer blocking cover 3 and the adapter flange 2 are fixedly connected by short screws 6 .
[0027] The transfer flange 2 is in the shape of a ring, the...

The invention discloses an inspection tool for a hydraulic test on a high pressure vessel. An inner plug cap is located in a container flange. A seam allowance on the inner surface of the inner plug cap is stuck to the inner surface of the container flange. An outer plug cap is located on the upper surface of an adapter flange. The lower surface of the adapter flange is located on the upper surface of the container flange. The inspection tool is suitable for a container with the diameter phi of 500-1200mm and pressure of 5 to 16MPa. In pressure detection, the sealing effect is guaranteed, therigidity of the flange is increased to reduce the deformation and threaded holes of the flanges are not used so that the quality of the threaded holes in the flanges is protected. Through the positioning seam allowances at sealing positions designed according to structure characteristics of the container flange, the corresponding plug cap limitation is realized and assembling errors are avoided. The inner seam allowance can improve the rigidity of the flange. An outer seam allowance limits the deformation of the container flange. The inspection tool realizes a flange connection structure-freecontainer hydraulic test and has the characteristics of simple structure and operation convenience.
Description
technical field [0001] The invention relates to a testing device for hydraulic testing in the mechanical industry, in particular to testing tooling for testing hydraulic testing of high-pressure containers. Background technique [0002] For pressure vessels used in the machinery industry, the front and rear openings generally have connection structures. The sealing structure generally adopts radial sealing or end face sealing structures, and is connected by flanges or key rings. The flange on the rear opening of the high-pressure vessel is When designing threaded holes, in order to reduce redundant quality, the safety factor of threaded hole design is low. However, the hydraulic detection strength is greater than the working pressure. In order to protect the connection thread, the design does not allow the use of the threaded hole on the rear opening flange to connect the hydraulic detection tooling, that is, the threaded hole on the flange cannot be used for hydraulic detec...
