Connection, output connecting cylinder 902 are threadedly coupled with the output end of steel cylinder delivery valve 10.Steel cylinder transfer valve 7 and steel in the present embodiment
Bottle delivery valve 10 is ball valve.Steel cylinder transfer valve 7 and steel cylinder delivery valve 10 can also be plate valve.
The left end of steel cylinder transfer valve 7 is connected with purging module 6, and valve interconnecting piece 604 and the input of the purging module 6 connect
Cylinder 901 is threadedly coupled, and the valve core chamber of the end face of valve interconnecting piece 604 and steel cylinder transfer valve 7 is every setting.
The right end of steel cylinder delivery valve 10 is connected with purging module 6, and valve interconnecting piece 604 and the output of the purging module 6 connect
Connect cylinder 902 is threadedly coupled, and the valve core chamber of the end face of valve interconnecting piece 604 and steel cylinder delivery valve 10 is every setting.Outer circulating tube 8
The purge passage 603 that one end purges module 6 with 7 left end of steel cylinder transfer valve is connected to, and the other end purges mould with 7 right end of steel cylinder delivery valve
The purge passage 603 of block 6 is connected to, can will be in pipeline by outer circulating tube 8 after filling medium in sampling steel cylinder 9
Completely purging is clean for medium.Check-valves 16 is provided on outer circulating tube 8, so as to avoid sampling when medium by outer circulation
Pipe 8 flows back.
The sampler is mainly used for the sampling of gas medium, and application method is as follows：Gas enters input by probe tube 2
In the sampling module 1 in the left side of sampling valve 5, then pass through communicating pipe, 11 left side of output sampling valve sampling module 1 after, through reflux
Pipe 15 flows out, to make the gas of 5 input terminal of input sampling valve remain recurrent state.
After opening input sampling valve 5 when sampling, gas is flowed into through steel cylinder transfer valve 7 in sampling steel cylinder 9, and through over sampling steel
The steel cylinder delivery valve 10 of 9 downside of bottle, output sampling valve 11 are back in return duct 15, complete the sampling of gas.
After the completion of sampling, input sampling valve 5 and output sampling valve 11 are closed, and closes steel cylinder transfer valve 7 and steel cylinder output
Then valve 10 opens blow down valve 4 and the gas medium in pipeline is blown into evacuated tube by exhaust-valve 12, nitrogen by outer circulating tube 8
In 13, hence into the attached discharge of 14 interior suction of adsorption tanks.Complete the sampling of gas.
