Testing device for hydrostatic pressure

Abstract

The invention discloses a testing device for hydrostatic pressure. The testing device comprises a high pressure vessel shell and a high pressure vessel cover, wherein a high pressure vessel cover frame is arranged at the top of the high pressure vessel shell; the high pressure vessel cover is arranged in the high pressure vessel cover frame; a cover base plate is mounted under the high pressure vessel cover; a locking sealing device is arranged on the high pressure vessel cover and is used for sealing the cover base plate; a sample device is arranged in the high pressure vessel shell; a camera module is arranged under the sample device; a water supply system is connected with the bottom of the high pressure vessel shell; the sample device comprises a sample and a sample cover; quick couplers are mounted on the sample cover; a camera position external frame for fixing the camera is fixedly mounted under the sample cover; a transparent block is mounted at the center of the camera position external frame; two quick couplers are mounted on the sample cover. The testing device for hydrostatic pressure provided by the invention is characterized in that the port of a tested sample is connected with an end cover bolt and is embedded in the chamber of the high pressure vessel, the disassembling is convenient and quick, the replacement is benefited and the true environment of the hydrostatic pressure can be accurately simulated.

Description

technical field [0001] The invention relates to a hydrostatic pressure test device, which is suitable for pressure simulation inside and outside a pressure-resistant casing, and belongs to the field of marine equipment. Background technique [0002] Submersibles are important equipment for ocean exploration and deep-sea scientific research. As an important part of the submersible, the pressure-resistant shell plays a role in ensuring the normal operation of internal equipment and the health and safety of personnel during the dive process. The research and development design of the pressure body is very important. [0003] Existing pressure test equipment is mainly divided into two types: one is that the end is subjected to unidirectional pressure instead of uniformly distributed pressure on the shell. This equipment can avoid the sealing difficulty of water pressure, and uses mechanical extrusion, which is simple and reliable in action. However, the test object is limited ...

AI Technical Summary

Problems solved by technology

However, the test object is limited to cylindrical shells, and it cannot accurately simulate the real environment of water pressure; the other is hydraulic equipment with uniform pressure on the shell

This equipment can accurately simulate the real environment of water pressure, but all of the test pieces are under single external or internal pressure, which may easily cause the test piece to crack

Secondly, the installation of the test piece is relatively complicated, which affects the test res
