Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model gas filling system.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
A kind of gas filling system, as shown in Figure 1, including storage tank 1, compress cell, vaporization unit, buffer cell and pressure regulation
Unit, storage tank 1, compress cell, vaporization unit, buffer cell and pressure regulation unit are sequentially connected,
Specifically, being stored with liquid oxygen in storage tank 1, compress cell includes two booster pumps 2, and vaporization unit includes two vaporizations
Device 3, in the embodiments of the present invention, vaporizer 3 is air vaporizer 3, and buffer cell includes surge tank 4, pressure regulation list
Member includes a pressure regulation valve group 5, and 2 input terminal of booster pump is connected to the lower end of storage tank 1 by pipeline, and each booster pump 2 is separately connected
One vaporizer 3, the output end of booster pump 2 are connected to the input terminal of the lower end of vaporizer 3, the output of vaporizer 3 by pipeline
End is connect by pipeline with the input terminal of the lower end of surge tank 4, and the output end of 4 upper end of surge tank passes through pipeline and pressure regulation valve group 5
Input terminal connection.The output end of pressure regulation valve group 5 connects gas cylinder to be inflated.
In the embodiments of the present invention, pressure regulation valve group 5 includes two homophony laminated structures and one pressure adjusting structure, master
Pressure adjusting structure includes two main pressure regulator valves 51, and surge bunker 52 is provided between two main pressure regulator valves 51, and secondary pressure adjusting structure includes one
A secondary pressure regulator valve 53.
The gas filling system of the utility model embodiment works in this way: the liquid oxygen stored in storage tank 1 is through pipeline stream
To two booster pumps 2, since there are two booster pumps 2 for setting, it is ensured that liquid nitrogen is sufficiently pressurized, and prevents pressurization insufficient, and more
Safety；It flows to air vaporizer 3 through pressurized liquid nitrogen sufficiently to be vaporized, it is different that vaporizer 3 can according to need setting
Specification is to guarantee the abundant vaporization of liquid oxygen；Liquid oxygen after vaporization first flows into surge tank 4, is become after being vaporized due to liquid oxygen by liquid
For gas, gas is inputted so needing to add surge tank 4 from tank body lower end, and exported from tank body upper end, guarantees output gas
It is gentle；Finally, the oxygen of gas is punched into gas cylinder to be inflated after pressure regulation unit pressure regulation.Pressure regulation unit is provided with main pressure regulator knot
Structure and time pressure adjusting structure, when normal, by homophony laminated structure pressure regulation, when homophony laminated structure breaks down, by secondary pressure adjusting structure tune
Pressure.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
