Technical field
The utility model relates to the field of gas distribution of mixed gas more particularly to a kind of high, normal, basic constant pressure air distributing devices.
Background technique
Calibrating gas using increasingly extensive, type and quantity are constantly being enriched, and are wanted to the quality of calibrating gas
It asks and is also being continuously improved.The preparation method of traditional standard gas has static volumetric method and Devince By Dynamic Gas Ration Method two major classes.Static distribution
Method includes: weight method, volumetric method and pressure ratio method.Wherein weight method is the substantially square of preparing calibrating gas generally acknowledged in the world
Method, it is to measure the quality of high-purity component gas and diluent gas respectively using high accuracy balance, and quantify mixing and prepare mark
The method of quasi- gaseous mixture.
In air distributing device in the prior art, raw material gas cylinder is connect after being filtered with feed control valve, raw material control
Valve processed is connect with high voltage adjusting system, and high voltage adjusting system is connect with low pressure regulating system again after connecting with pressure sensor one,
Low pressure regulating system is connect with control of product valve, emptying control valve, vacuum pump valve respectively after connecting with pressure sensor two;Product
It is placed on electronic balance, the data of the signal and balance of pressure sensor one and pressure sensor two access signal processing system
System, synchronous signal processing system are also connect with data processing system, emptying control valve and vacuum pump interlock respectively.This device
Using weight method distribution, equipment is simple, easy to operate, improves work efficiency and weighing accuracy.But above-mentioned apparatus is primary only
One bottle of gas, and the low concentration Standard Gases small for molecular weight can be filled, distribution precision can be reduced, and the utilization rate of unstripped gas is not
Foot.
Utility model content
The purpose of this utility model is: providing a kind of high, normal, basic constant pressure air distributing device, can be improved the benefit of unstripped gas
With rate.
In order to achieve the above purposes, the technical solution adopted by the utility model is:
High, normal, basic constant pressure air distributing device, including raw material gas cylinder, the gas outlet of the raw material gas cylinder and the first four-way pipe
The connection of a nozzle, the other three nozzle of first four-way pipe passes through three of three pipelines and the second four-way pipe respectively
Another nozzle of nozzle connection, second four-way pipe is connected to by pipeline with the inflating port for filling gas cylinder, described to fill
Gas cylinder is arranged on an electronic balance, on three pipelines that first four-way pipe is connected to three nozzles of the second four-way pipe respectively
It is provided with pressure reducing valve and valve.
The utility model also includes the following features:
Ball valve and pressure gauge are respectively arranged on the pipeline that second four-way pipe is connected to the inflating port for filling gas cylinder.
Compared with prior art, the technical effect that the utility model has are as follows: the utility model is connected with air distributing device, increases
Add three pressure reducing valves, then three pressure gradients that raw material is decompressed to suitable distribution are sequentially added by low middle high sequence
Balance Air, therefore the arrangement increases the utilization rates of unstripped gas.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of high, normal, basic constant pressure air distributing device.
Specific embodiment
Below with reference to Fig. 1, this high, normal, basic constant pressure air distributing device is described in further detail:
High, normal, basic constant pressure air distributing device, including raw material gas cylinder 10, the gas outlet and the one or four of the raw material gas cylinder 10
One nozzle of siphunculus 20 is connected to, and the other three nozzle of first four-way pipe 20 passes through three pipelines and the second four-way respectively
Three nozzles of pipe 30 are connected to, another nozzle of second four-way pipe 30 passes through pipeline and the inflating port for filling gas cylinder 40
Connection, the gas cylinder 40 that fills are arranged on electronic balance 50, three pipes of first four-way pipe 20 and the second four-way pipe 30
Pressure reducing valve 60 and valve 70 are respectively arranged on three pipelines of mouth connection;
The utility model is connected with air distributing device, increases by three pressure reducing valves 60, and raw material is decompressed to three of suitable distribution
Then pressure gradient sequentially adds Balance Air by low middle high sequence, therefore the arrangement increases the utilization rates of unstripped gas.
For convenience of close gas source and fill pressure on gas cylinder 40, second four-way pipe 30 with fill gas cylinder 40
Ball valve 80 and pressure gauge 90 are respectively arranged on the pipeline of inflating port connection.
It, can be real in other specific forms and without departing substantially from the spirit or essential attributes of the utility model
Existing the utility model.Therefore, it in all respects, the embodiments should be taken as exemplary, and is non-limited
, scope of this utility model is limited by the appended claims rather than the above description, it is intended that claim will be fallen in
All changes in the meaning and scope of equivalency are embraced therein.It should not be by any attached drawing in claim
Label is construed as limiting the claims involved.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
