Description
Technical field
The present invention relates to a kind of sampling test point scavenging pipeline for on-site gas analyzer.
Background technology
On-site gas analyzer collection sampling test point gas is analyzed to be used for instructing and is produced, and sampling test point is generally all installed filtrator, and the easy dust stratification of filtrator stops up, and needs often purging, and is unimpeded to guarantee; On-site gas analyzer installation site and point position are different, in eminence or rugged surroundings, flue position as the power generator group, each cleaning measuring point filtrator must carry out the dismounting of sampling head, and so not only maintenance workload is big, complex procedures, efficient is low, and the dust stratification degree of filtrator is not easy to grasp, and causes the analyser data error, influences ordinary production.
Summary of the invention
Technical matters to be solved by this invention provides a kind of sampling test point scavenging pipeline for on-site gas analyzer, utilize this pipeline can conveniently realize the purging of sampling test point, also can realize simultaneously control to the sampling line blockage, guarantee the accuracy of analyser data, reduce maintenance workload, improved maintenance efficiency.
For solving the problems of the technologies described above, sampling test point scavenging pipeline for on-site gas analyzer of the present invention comprises the sampling line between on-site gas analyzer and sampling test point, also comprises gas meter, first air valve, second air valve, the 3rd air valve, first three-way connection, second three-way connection, the 3rd three-way connection, source of the gas and some connecting pipes; Described first three-way connection is located on the sampling line between described analyser and sampling test point, described source of the gas connects described the 3rd three-way connection, first air valve, gas meter, second air valve, second three-way connection and first three-way connection successively by described some connecting pipes, described the 3rd a three-way connection end again connects described the 3rd air valve one end by described connecting pipe, and the other end of described the 3rd air valve connects an end again of described second three-way connection by described connecting pipe.
This scavenging pipeline also comprises gas pressure reducer, and described gas pressure reducer is connected between described source of the gas and the 3rd three-way connection.
For accurately judging the stopping state of sampling line, the range of above-mentioned gas flowmeter is chosen as 0-150ml/min.
Be the reliable connection of this scavenging pipeline, above-mentioned first three-way connection, second three-way connection and the 3rd three-way connection are copper joints, and described some connecting pipes are copper pipes.
Because sampling test point scavenging pipeline for on-site gas analyzer of the present invention has adopted technique scheme, one three-way connection promptly is set between sampling line, source of the gas is connected to this three-way connection by flowmeter and two air valves, and source of the gas directly is connected to this three-way connection by an air valve more simultaneously; Utilize this pipeline can conveniently realize the purging of sampling test point, also can realize control simultaneously, guarantee the accuracy of analyser data, reduced maintenance workload, improved maintenance efficiency the sampling line blockage.
Description of drawings
The present invention is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of on-site gas analyzer sampling test point scavenging duct of the present invention.
Embodiment
As shown in Figure 1, sampling test point scavenging pipeline for on-site gas analyzer of the present invention comprises the sampling line 3 of 1 of on-site gas analyzer 2 and sampling test point, also comprises gas meter 12, first air valve 9, second air valve 10, the 3rd air valve 11, first three-way connection 6, second three-way connection 8, the 3rd three-way connection 7, source of the gas 4 and some connecting pipes 13; Described first three-way connection 6 is located on the sampling line 3 of 1 of described analyser 2 and sampling test point, described source of the gas 4 connects described the 3rd three-way connection 7, first air valve 9, gas meter 12, second air valve 10, second three-way connection 8 and first three-way connection 6 successively by described some connecting pipes 13, described the 3rd three-way connection 7 end again connects described the 3rd air valve 11 1 ends by described connecting pipe 13, and the other end of described the 3rd air valve 11 connects an end again of described second three-way connection 8 by described connecting pipe.
This scavenging pipeline also comprises gas pressure reducer 5, and described gas pressure reducer 5 is connected between described source of the gas 4 and the 3rd three-way connection 7.
For accurately judging the stopping state of sampling line, the range of above-mentioned gas flowmeter 12 is chosen as 0-150ml/min.
Be the reliable connection of this scavenging pipeline, above-mentioned first three-way connection 6, second three-way connection 8 and the 3rd three-way connection 7 are copper joints, and described some connecting pipes 13 are copper pipes.
Sampling test point scavenging pipeline for on-site gas analyzer of the present invention is provided with a three-way connection between sampling line, source of the gas is connected to this three-way connection by flowmeter and two air valves, and source of the gas directly is connected to this three-way connection by an air valve more simultaneously; During the gas analyzer operate as normal, three air valves of this scavenging pipeline are all closed, the sampling work of not impact analysis instrument at the scene; This scavenging pipeline is when censored sample line clogging situation, at first close the 3rd air valve, open first and second air valves, this moment, source of the gas was flowed through first air valve, gas meter, second air valve to sampling line, observe the gas meter indicating value and can judge the sampling line blockage,, illustrate that there is obstruction in measuring point if flow is lower, if flow is normal, illustrate that then sampling pipe is unimpeded; This scavenging pipeline is at first closed first and second air valves when purging measuring point, open the 3rd air valve, and this moment, source of the gas was flowed through the 3rd air valve to the sampling line measuring point, can realize the purging to the measuring point filtrator, removed dust stratification, guaranteed the cleaning of measuring point filtrator.Utilize this pipeline can conveniently realize the purging of sampling test point, also can realize control simultaneously, guarantee the accuracy of analyser data, reduced maintenance workload, improved maintenance efficiency the sampling line blockage.
