Description

Technical Field

[0002] Pressure testing chambers are used to store deep-sea samples and conduct deep-sea environment simulation experiments. For example, the Chinese utility model patent "CN204746339U, entitled 'A Novel High-Strength Deep-Sea Simulation High-Pressure Testing Chamber'" includes a support, a high-pressure chamber body, a sealed end cap, and a shear ring opening and closing device. The high-pressure chamber body's axis is perpendicular to the horizontal plane, and it includes an arc-shaped end and a cylindrical body. The arc-shaped end and the end of the cylindrical body are connected to form a cavity structure with an axial cross-section of "U". The outer surface of the arc-shaped end abuts against the support. The upper end of the cylindrical body is connected to the sealed end cap and the shear ring opening and closing device. At least two flow guides are provided on the arc-shaped end, and a drainage conduit is provided at each flow guide. A reinforcing mechanism is provided at the front end of the drainage conduit. The support includes a base plate, a vertical plate, and side plates. Due to the high pressure of the deep-sea environment, this technology is fully enclosed, making it impossible to observe its internal state.
