Problems solved by technology

The metal sealing ring is not only expensive, but also not reusable, that is, the metal sealing ring can only be used once due to its irreversible plastic deformation, and there is no report on the pressure test device capable of simulating the deep underwater pressure environment of the whole sea.

Abstract

The present invention relates to myriametric underwater pressure testing equipment. It is formed from longitudinal beam, sealed oil cylinder, end cover and test cylinder, etc. Said invention provides the concrete structure of said longitudinal beam and the concrete connection mode of all the above-mentioned components. Besides, said invention also includes a hydraulic drive system.

Description

technical field [0001] The invention relates to a pressure test device for the deep underwater pressure environment of the whole sea, in particular to a 10,000-meter water pressure test device. Background technique [0002] At present, most of the pressure test devices under the underwater pressure environment are sealed by rubber sealing rings and fastened by bolts. The maximum test pressure is 75MPa, the maximum working pressure is 72MPa, and the connection between the end cover and the test cylinder is manually tightened. A plurality of bolts arranged in a circle is realized. In the past, metal sealing rings were mostly used for sealing in high-pressure and ultra-high-pressure environments. The metal sealing ring is not only expensive, but also not reusable, that is, the metal sealing ring can only be used once due to its irreversible plastic deformation, and there is no report on the pressure test device capable of simulating the deep underwater pressure environment of ...
