Description
Technical field
This utility model relates to a kind of micro amount of oxygen quick analytical sampling system.
Background technology
For the analysis of Traces of Oxygen in Gases, existing sampler, during connecting sample, can admit air into
Sampler, a large amount of oxygen in air can together be brought into system, thus need with plenty of time and sample gas by the entrance of air
The impact of air could be eliminated, the most time-consuming but also effort；During analyzing micro amount of oxygen, need to continue to trace oxygen analyzer
Being passed through sample gas, such sample gas is consuming the most always, so analysis time is the longest, the sample gas of consumption is the most；This outer analysis is tied
The repeatability of fruit is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of micro amount of oxygen quick analytical sampling system, efficiently solves trace in gas
The difficult problem that oxygen analysis time is longer.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is:
A kind of micro amount of oxygen quick analytical sampling system, including cross valve, oxygen analyzer, described cross valve has first even
Connecing end, the second connection end, the 3rd connection end and the 4th connection end, the first described connection end connects sample gas air inlet pipe, described
The 3rd connection end connect purge gas air inlet pipe, described 4th connection end connect described in oxygen analyzer.
Preferably, the second described connection end emptying connects.
Preferably, described purge gas air inlet pipe connects Nitrogen source gases.
Preferably, when described system is not analyzed, the first connection end of described cross valve, the second connection end are even
Logical, the 3rd connects end, the 4th connection end connection；When described system carries out micro amount of oxygen analysis, the first of described cross valve
Connecting end, the 4th connection end connection, second connects end, the 3rd connection end connection.
Preferably, described cross valve is plane four-way valve.
Owing to technique scheme is used, this utility model compared with prior art has the advantage that
This utility model is prevented effectively from, by the conversion of cross valve, the impact that micro amount of oxygen is analyzed by air；Realize quickly dividing
Analysis；Effectively save sample gas consumption, improve the repeatability of analysis result.

Accompanying drawing 1 is the schematic diagram that the present embodiment does not carry out oxygen analysis state；
Accompanying drawing 2 carries out oxygen for the present embodiment and analyzes the schematic diagram of state.
Wherein: 1, cross valve；10, first connects end；11, second connects end；12, the 3rd connects end；13, the 4th connects
End；2, oxygen analyzer；3, sample gas air inlet pipe；4, purge gas air inlet pipe.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by embodiment:
A kind of micro amount of oxygen quick analytical sampling system, including cross valve 1, oxygen analyzer 2.In the present embodiment:
Cross valve 1 uses plane four-way valve, cross valve 1 to have first connection end the 10, second connection end the 11, the 3rd connection end
12 and the 4th connect end 13.Wherein: first connects end 10 connects sample gas air inlet pipe 3, and second connects end 11 emptying connects, the 3rd
Connecting end 12 and connect purge gas air inlet pipe 4, the 4th connects end 13 connects oxygen analyzer 2.
Purge gas air inlet pipe 4 connects the lowest Nitrogen source gases of oxygen content.
As shown in Figure 1: when system does not analyzes sample gas, the first connection end 10, second of cross valve 1 connects end 11 and connects, the
Three connect end the 12, the 4th connection end 13 connects, and now sample gas connects end 11 sky from the first connection end 10 to the second of cross valve 1
Row, is sufficiently displaced from sample gas air inlet pipe 3, and nitrogen then connects end 13 from the 3rd connection end 12 of cross valve 1 to the 4th, enters oxygen analysis
Instrument 2, carries out oxygen analyzer 2 completely cutting off air conservation；
As shown in Figure 2: when system carries out micro amount of oxygen analysis: cross valve 1 rotates counterclockwise 90 °, the first of cross valve 1 is even
Connecing end the 10, the 4th to connect end 13 and connect, second connects end the 11, the 3rd connects end 12 and connects, and sample gas connects end 10 to the from first
Four connect end 13, enter oxygen analyzer 2 and are analyzed, and nitrogen then connects end 11 from the 3rd connection end 12 to the second of cross valve 1
Idle discharge, owing to the detected value of oxygen analyzer 2 is always held at the lowest level, so sample gas one enters oxygen analyzer 2, the most just
Analysis result can be obtained；
After completing micro amount of oxygen analysis: cross valve 1 is rotated clockwise 90 °, as it is shown in figure 1, sample gas at this moment can be closed, disconnect
Sample gas and the connection of system.Owing to eliminating the air interference to sample, so having good repeatability during repetitive measurement.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow and is familiar with technique
Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All according to this utility model spirit made equivalence change or modify, all should contain protection domain of the present utility model it
In.
