Abstract

The invention discloses a hyperbaric cabin device for an external pressure test of a pressure container model. The hyperbaric cabin device mainly comprises a hyperbaric cabin barrel, an annular pressure container fixing disc, an annular hyperbaric cabin cover and a protective cover which are coaxially arranged from bottom to top. The device can carry out an external bulge test on the pressure container model. The device can conveniently measure the strain of the inner wall of the pressure container model, the leakage problem caused when watertight sensing parts, sealing rings and the like are adopted for strain measuring in the prior art is avoided, in this way, the inner wall of the pressure container model directly makes contact with the exterior, further expansion can be achieved on the basis, and multiple kinds of data, such as pressure, temperature and displacement, needed for tests are measured; the protective cover can protect testers during conquassation of the pressure container model, and the hyperbaric cabin device with multiple pressure grades can be obtained by designing the structural sizes of the cabin barrel, the cabin cover, bolts and nuts.

Description

technical field [0001] The invention relates to a hyperbaric chamber device for testing, in particular to a hyperbaric chamber device for external pressure testing of a pressure vessel model. The device can perform the test by externally pressing the pressure vessel model. Background technique [0002] During the design process of pressure vessels, it is an essential step to perform external pressure tests on them. Existing external pressure test devices are generally fully sealed hyperbaric chambers. The pressure vessel model needs to be completely placed in the hyperbaric chamber. The electronic signals collected by the test are connected to the watertight cable through the watertight connector on the bulkhead of the hyperbaric chamber to realize the data transmission function. The existing external pressure test methods have problems such as easy leakage, easy damage to watertight joints, easy damage to sensors, and high testing costs. Contents of the invention [0003...
