Specific embodiment
A kind of gas chromatogram dilutes air intake installation, and which includes：Eight ways valve 16 is sequentially connected carrier gas interface 1, is diluted gas
Interface 2, sampling probe 8 and air tube 7 is taken, sampling probe 8 and takes air tube 7 and be connected to relative interface, taken air tube 7 and be connected with six-way valve 12,
In addition six-way valve 12 is connected with water tumbler 15, six-way valve carrier gas inlet 10 and six-way valve carrier gas outlet 11 by pipeline respectively, clematis stem
Valve carrier gas inlet 10 and six-way valve carrier gas outlet 11 are connected to two adjacent interfaces of six-way valve 12, water tumbler 15 and take air tube 7 and connect
Two in addition adjacent interfaces of six-way valve 12 are connected on, the interface of the two connection is relative, remaining two interfaces are connected by quantitative loop 13
Logical.16 another two of eight ways valve respectively with sampling probe 8 and take air tube 7 adjacent interface connection stop valve D6 and stop valve B4.Carrier gas
Stop valve A is set between interface 1 and eight ways valve 16；It is diluted between gas interface 2 and eight ways valve 16, arranging shutoff valve C 5.Take gas
Stop valve E9 is set between pin 7 and six-way valve 12.Six-way valve carrier gas inlet 10 is connected with carrier gas source of the gas, and six-way valve carrier gas is exported
11 are connected with the injection port of gas chromatogram, and quantitative loop 13 makes the gaseous sample of fixed volume fully enter gas chromatogram, eight ways valve
16 according to the needs for taking gas and mixed gas, can rotate with 90 degree clockwise counterclockwise.
Functional realiey process：
Take air tube 7 to clean：Such as Fig. 2；Carrier gas interface 1 and carrier gas UNICOM, take air tube 7 and carrier gas interface 1, stop valve A3, cut
Zhi Fa B4 UNICOMs, stop valve A3 open, and stop valve B4, stop valve E9 are closed, and take air tube 7 and pull up the certain carrier gas of absorption,
Then cut-off penalizes B4 to open, and takes air tube 7 and pushes down on discharge gas.
Take air tube 7 and take gas：Take air tube 7 cleaning terminate after, cut-off penalize B4 close, according to extension rate needs, take air tube 7 to
Upper pulling draws certain carrier gas, and then stop valve A3, B4 is closed.
Sampling probe 8 is cleaned：Be diluted gas interface 2 and be diluted gas UNICOM, sampling probe 8 be diluted gas interface 2,
Shutoff valve C 5, stop valve D6 UNICOMs, shutoff valve C 5 open, and stop valve D6 is closed, sampling probe 8 pull downward on draw certain dilute
Sample gas is released, then cut-off penalizes C5 to close, and stop valve D6 is opened, and sampling probe 8 pushes up discharge sample gas.
Sampling probe 8 takes gas：After the cleaning of sampling probe 8 terminates, cut-off penalizes D6 to close, according to extension rate needs, sampling probe 8 to
What lower pulling absorption was certain is diluted gas, and then shutoff valve C 5, D6 is closed.
Gas mixing：Such as Fig. 3, take air tube 7 and sampling probe 8 according to extension rate need to measure a certain amount of carrier gas with dilute
After outgassing body, 16 dextrorotation of eight ways valve turn 90 degrees, carrier gas pin 7 and 8 UNICOM of sampling probe, and stop valve E9 is closed, and then takes air tube 7
Promoted up and down for several times in one direction with sampling probe 8 simultaneously, carrier gas is sufficiently mixed with gas is diluted, then sampling probe
