Description
Technical field
This utility model is related to a kind of gas sampling detection means, specifically a kind of gas sampling dress for gas piping
Put.
Background technology
At present when to dust content of gas in gas piping and gas componant sampling analyses, commonly used on-line determination and handss
Work measures two kinds of methods, and both of these approaches all has different defects, the poor anti-interference of on-line determination equipment, probe be fragile,
Operating cost is high, difficult in maintenance；Time-consuming, potential safety hazard big for conventional manual mensure, complex operation, error in data are big；Simultaneously by
It is all located at malleation section in the sample position of gas piping, in pipeline, water capacity is high, pipeline pressure 0.7-3Kg/cm2, and some are even
Bigger, there is certain potential safety hazard in the gas sampling of traditional-handwork test, and affect sampling precision；Regardless of whether being on-line determination
Or manual mensuration mode, primary sample can only obtain a sample, then this sample is divided into some deciles to be measured respectively,
The time that therefore do not account for isoparametric impact on dust content of gas, that is, the parameter in coal gas in different time sections may not
Same, lead to testing result that deviation occurs.
Utility model content
The purpose of this utility model is to provide a kind of gas sampling device for gas piping, to solve above-mentioned background
The problem proposing in technology.
For achieving the above object, this utility model provides following technical scheme：
A kind of gas sampling device for gas piping, including：Gas piping, three way cock, main sampling tube, manifold
Joint, point sampling tube and sampling box, the two ends of described three way cock connect gas piping by flange respectively, and another one connects
Mouthful connect main sampling tube, described main sampling tube connects manifold adapter, described manifold adapter arranges multiple interfaces, described point
Sampling tube is arranged on the interface of manifold adapter, described sampling box be seal case structure, if its in setting dry seal every
Sampling box is divided into some independent sampling units by plate, and each sampling unit is all connected with a point sampling tube；Divide and all pacify on sampling tube
Dress electromagnetic valve, the control circuit order of connection control circuit of described electromagnetic valve and intervalometer, electromagnetic valve is normally off.
As further program of the utility model：It is respectively provided with sample tap on described sampling unit.
As further program of the utility model：It is respectively mounted pressure transducer, described pressure passes in described sampling unit
