Embodiment Construction

[0017] As shown in the figure, a test container simulating a high-pressure marine environment includes a container body 2 and a flat cover 1. The container body 2 is welded by a joint 21 at the head, a test cylinder 22 in the middle, and a seal 23 at the bottom. They are all made of steel, and the thickness of the test cylinder 22 and the head 23 reaches 27 mm. The cross section of the head 23 and the test cylinder 22 is circular, and the inner wall surface of the head 23 is a hemispherical surface, so that the test cylinder 22 and the head 23 are tangent at the welding point, and there are no edges and corners, so there is no weakened strength. problem. The bottom of the container body 2 is also provided with a skirt 3 for supporting it, and a threaded hole is provided on the skirt of the skirt 3 for fixed connection with the ground.

[0018] The top surface of the flat cover 1 is provided with a vertically penetrating water injection hole 11, a pressure measuring hole 12, a wa...

Abstract

The invention discloses a test container for imitating deep-sea high-pressure environment, comprising a container body and a flat cover which is hermetically cooperated with the container body; wherein a water injection hole and a pressure measurement hole which are vertically penetrated are arranged at the centre of the top surface of the flat cover, a cylindrical lug matched with the inner chamber of the head of the container body is arranged at the centre of the bottom surface of the flat cover and the rest part of the bottom surface of the flat cover is completely matched with the top surface of the container; mutually matched annular steps are arranged on the peripheral surface of the cylindrical lug and the inner wall at the head of the container body, and an annular sealing ring made of soft metal materials is arranged between the two annular steps; the flat cover is in connection and close fit with the container body through screws and bolts, and press annular gaskets to deform plastically. The container of the invention presses the annular gaskets made of soft metal materials to deform plastically, increases the sealing property among the annular gaskets, and ensures that the container can bear the high hydrostatic pressure in the deep sea, thereby avoiding the troubles of testing the ocean engineering equipment in the deep sea.

Description

Technical field [0001] The invention relates to the technical field of marine engineering tests, in particular to a test container simulating a deep-sea high-pressure environment. Background technique [0002] Marine engineering equipment (including submarine pipelines, deep-sea oil production systems, etc.) are subject to high hydrostatic pressure. In order to verify whether these equipment can work normally under high pressure, a hydraulic test is usually required. At the same time, because it is very difficult to directly monitor deep-sea equipment, the test container used to simulate the deep-sea high-pressure environment is particularly important. [0003] At present, pressure vessels commonly used in the industry are mostly used to store gas or liquefied gas. The inlet and outlet of materials are generally completed by opening and connecting pipes, without opening and closing the flat cover, and the sealed state of the pressure vessel can be well maintained. In the hydrost...
