Rapid escape wetsuit inflation system

Abstract

The invention provides an inflatable system for a fast-escape diving suit. The inflatable system comprises an air inlet controller, an air supplying pipeline, an air bag connecting valve and a feedback pipeline; the air inlet controller supplies air to the air bag connecting valve through the air supplying pipeline, and the air bag connecting valve feeds back the inflation pressure through the feedback pipeline; the air inlet controller comprises a control valve, and the control valve comprises a control valve stem and a feedback chamber; the air bag connecting valve comprises a feedback valve and a feedback interface; air passes through the feedback valve and enters the feedback pipeline through the feedback interface, and then enters the feedback chamber; and the air pressure in the feedback chamber pushes the control valve stem to move and changes the size of a passage of the air inlet controller. The inflatable system for the fast-escape diving suit has the advantage that the air supplying amount can be automatically adjusted according to pressure change in a rapid pressure chamber, security risks are eliminated, and it is ensured that a diver can escaped from underwater safely and quickly.

Description

technical field [0001] The invention relates to an inflation system, in particular to an inflation system for a quick escape diving suit. Background technique [0002] The main function of the quick escape diving suit inflation system is to ensure the normal gas supply of the diver in the quick escape diving suit. With the continuous development of deep-sea operations, people pay more and more attention to the research on divers' underwater escape. When implementing underwater escape, divers need to wear quick escape diving suits, enter the rapid pressurization chamber to pressurize, and after the pressure in the rapid pressurization chamber is balanced with the external water pressure, open the upper cover of the pressurization chamber, and the diver leaves the rapid pressurization chamber , Relying on the buoyancy provided by the quick escape diving suit, quickly float to the surface. During the pressurization process in the rapid pressurization chamber, it is necessary ...

AI Technical Summary

Problems solved by technology

In the past, the air supply volume of the inflatable system could not be automatically adjusted with the pressure change of the rapid pressurization chamber, and there were potential safety hazards such as crushing injuries and drowning of divers due to too small air supply volume, or rupture of the air bag of the rapid escape diving suit due to excessive air supply volume.
