High-pressure gas storage device integrating pressure control and monitoring

Abstract

The invention relates to a high-pressure gas storage device integrating pressure control and monitoring. The high-pressure gas storage device comprises a gas cylinder, a gas cylinder stop valve, a pressure reducing valve, a gas cylinder pressure sensor and an inflation wrench, wherein the gas cylinder stop valve is provided with four connecting ports which are correspondingly connected with the gas cylinder, the gas cylinder pressure sensor, the pressure reducing valve and an inflation gas source, the gas cylinder pressure sensor is connected with the gas cylinder, the gas cylinder stop valveis connected with the pressure reducing valve through a transition pipeline, the gas cylinder stop valve comprises a stop valve and an inflation valve, the stop valve is used for controlling high-pressure gas in the gas cylinder to be output into the pressure reducing valve, the pressure reducing valve is used for outputting gas which is constant in a set pressure range, the inflation valve is connected with the gas cylinder and used for controlling the inflation gas source to inflate the gas cylinder, the inflation wrench is used for opening the inflation valve, and the inflation speed is controlled by controlling the opening degree of the inflation valve. According to the high-pressure gas storage device, the inflation speed can be controlled by opening the inflation valve of the gas cylinder stop valve through the inflation wrench without detaching the pressure reducing valve and a pressure monitoring device, and the pressure change in the gas cylinder can be monitored in real time.

Description

technical field [0001] The invention belongs to the field of astronaut support in spacecraft, and in particular relates to a high-pressure gas storage device integrating pressure control and monitoring. Background technique [0002] As an important gas supply and pressure regulating device for spacecraft, the high-pressure gas storage device can provide life support and working environment for astronauts in the space station. High-pressure gas storage devices are used in many fields, such as underwater and vacuum environments, which require oxygen supply and pressure changes. Most of the existing high-pressure gas storage devices are installed separately from gas cylinders, pressure reducing valves, gas cylinder shut-off valves and pressure monitoring devices. When inflating, the pressure reducing valves and pressure monitoring devices need to be removed, which brings inconvenience to people’s operation. inconvenient. [0003] In the prior art, there is a switching scheme ...
