Deep sea high pressure environment simulation device capable of reducing requirement for wall thickness and material strength

Abstract

The invention discloses a deep sea high pressure environment simulation device capable of reducing requirement for wall thickness and material strength. The deep sea high pressure environment simulation device consists of an outer cylinder, an external shearing resistance block, an outer sealing ring, an outer flat cover, an inner cylinder, an inner shearing resistance block, an inner sealing ring and an inner flat cover. The deep sea high pressure environment simulation device has an inner high pressure cavity and an outer high pressure cavity; the inner high pressure cavity is a working pressure cavity; when the outer high pressure cavity and the inner high pressure cavity are filled with high pressure oil; the cylinder wall of the inner cylinder is under the affect of the pressure difference of two cavities; compared with the traditional device, the one-way impact sustained by the wall of the inner cylinder is greatly reduced; in the meantime, when the wall of the inner cylinder are under the affect of the high pressure oil on two sides, a certain extrusion deformation is produced so as to improve the strength of the cylinder wall. The invention reduces the requirement for the thickness of the wall of the inner cylinder and the material strength.

Description

technical field [0001] The invention relates to a deep-sea high-pressure environment simulating device, in particular to a deep-sea high-pressure environment simulating device that can reduce the wall thickness and material strength requirements. Background technique [0002] Deep sea operation equipment must withstand high hydrostatic pressure. In order to verify whether the equipment can work normally under high hydrostatic pressure, it is usually necessary to use a deep-sea high-pressure environment simulator to do a high-pressure test. At present, with the increasing frequency of deep-sea exploration activities, the high pressure test of 110MPa level is very necessary. Considering the safety factor, the working pressure of the deep-sea high-pressure environment simulator should reach a higher level. Taking the 1.5 times safety factor as an example, the working pressure of the deep-sea high-pressure environment simulator is at least 165MPa. [0003] According to the fo...
