Abstract

The invention discloses an uninterrupted gas supply device which comprises a first gas delivery manifold, a first pneumatic valve, a second gas delivery manifold and a second pneumatic valve. One endof the first gas delivery manifold is communicated with a main gas supply source while the other end of the same is communicated with a gas output pipeline or a gas output port, the first pneumatic valve is arranged on the first gas delivery manifold and is a normally-closed valve, one end of the second gas delivery manifold is communicated with a standby gas source while the other end of the sameis communicated with the gas output pipeline or the gas output port, and the second pneumatic valve is arranged on the second gas delivery manifold and is a normally-open valve. The main gas supply source and the standby gas source are serially connected to be switched mutually in a full-automatic manner within 0.5-1s, so that continuous gas use of gas using units is ensured.

Description

technical field [0001] The invention relates to the technical field of medical equipment. More particularly, the present invention relates to uninterruptible gas supply devices. Background technique [0002] Gas supply systems in many fields such as industry and medical treatment require uninterrupted gas supply, and the types and pressure levels of the supplied gases are also different. In order to achieve uninterrupted gas supply, two gas sources are used, one of which is the main gas supply source, and the other is the backup gas source. When the pressure of the main gas supply source drops to a predetermined value, switch the backup gas source, that is, the backup gas source starts to supply gas, and outputs through the uninterrupted gas supply device to realize uninterrupted gas supply. [0003] At present, the switching devices on the market include electromagnetic valve control switching and gas pressure difference switching devices. The gas supply sources of these ...
