Problems solved by technology

[0002] The background of this technical invention is based on the pressure and resistivity multi-measuring point side-bottom water model system, which seals the square plate model under high pressure conditions and sets multiple sets of pressure and resistance measuring points on the model. These measuring points All need to meet the sealing under high pressure conditions. The traditional sealing method is realized by resin glue casting. This method can only be used once, cannot be reused, and the molding cycle is long, so we designed the current sealing The structure is fully realized in the form of a rubber sleeve, and the sealing effect is achieved in a multi-point high-pressure environment. At the same time, this structure can be reused many times, and the molding cycle is short.

Abstract

The invention provides a high pressure sealing device for a multi-measuring point square model. The high pressure sealing device for the multi-measuring point square model comprises a square model body; the square model body is placed in a rubber sleeve; a left sealing plug and a right sealing plug are separately installed at the left end and the right end of the rubber sleeve; the left sealing plug and the right sealing plug are connected through pull rods; a probe assembly sealing compression ring is installed on a hollow cylinder on the rubber sleeve, and a resistance probe sealing assemblyand a pressure probe sealing assembly are inserted in a hollow cylindrical central hole; the resistance probe sealing assembly comprises a resistance pin, an insulated sealing joint and a probe sealing ring; and the pressure probe sealing assembly comprises a pressure probe sealing ring compression nut, a pressure probe sealing joint, a pressure probe sealing ring and a pressure probe. The high pressure sealing device for the multi-measuring point square model realizes the high pressure sealing of multiple groups of measuring points, and meanwhile, the portability of the installation of the measuring points and the stability of the sealing effect are realized.
