Model utility content
The purpose of this utility model is the problem that the fluctuation solving ambient temperature affects sample gas, the Tempeerature-constant air sampling distribution piping providing a kind of heating air to sample house steward.
The technical solution adopted in the utility model is: a kind of Tempeerature-constant air sampling distribution piping, comprise steel pipe and the stainless steel decorative tube of inner liner polytetrafluoroethylene pipe, perlite is filled between the steel pipe of inner liner polytetrafluoroethylene and stainless steel decorative tube, one end of distribution piping is connected with sampling joint, and sampling joint is through the steel pipe of inner liner polytetrafluoroethylene, perlite and stainless steel decorative tube collection conduit internal information; The internal chamber wall of the steel pipe of described inner liner polytetrafluoroethylene connects temperature sense and control gear.
As further improvement of the utility model, described temperature sense and control gear comprise heating tape, the temperature transducer of affixed heating tape and the temperature control box that is connected with temperature sensor signal.
As further improvement of the utility model, described heating tape and temperature transducer integrated setting.
Further improve as of the present utility model, described sampling joint and various gas analyzer linkage section all have Insulation.
The beneficial effect that the utility model adopts is: through Tempeerature-constant air sampling distribution piping by the various gas analyzer of feeding harmless for sample gas, ensure that the accuracy of gas-monitoring data, the maximized damage reduced various gas analyzer from source.The perlite of the Tempeerature-constant air sampling distribution piping of this structure has effect sample gas being kept to constant temperature, avoids the impact of fluctuation on sample gas of ambient temperature, substantially increases the accuracy of gas-monitoring data.The distribution piping of Tempeerature-constant air sampling is simultaneously provided with the temperature sense and control gear that regulate line temperature, and energy is regulating and control line temperature in real time, by pipeline gas temperature stabilization on set temperature point.Easy for installation, compact structure, manufactures cheap feature.
Accompanying drawing explanation

Shown in figure: 1 steel pipe, 2 perlites, 3 stainless steel decorative tubes, 4 sampling joints, 5 heating tapes, 6 temperature transducers, 7 temperature control boxs.
Embodiment
Below in conjunction with Fig. 1 and Fig. 2, the utility model is described further.
As shown in the figure, a kind of Tempeerature-constant air sampling distribution piping, comprise steel pipe 1 and the stainless steel decorative tube 3 of inner liner polytetrafluoroethylene pipe, perlite 2 is filled between the steel pipe 1 of described inner liner polytetrafluoroethylene and stainless steel decorative tube 3, one end of distribution piping is connected with sampling joint 4, and described sampling joint 4 is through the steel pipe 1 of inner liner polytetrafluoroethylene, perlite 2 and stainless steel decorative tube 3 collection conduit internal information; The internal chamber wall of the steel pipe 1 of described inner liner polytetrafluoroethylene connects temperature sense and control gear.
Tempeerature-constant air sampling distribution piping is total to two-layer composition by outer and internal layer, outer field is stainless steel decorative tube 3, and internal layer is the steel pipe 1 of inner liner polytetrafluoroethylene pipe, fills expanded perlite 2 between the two, expanded perlite 2 plays insulation effect, makes line temperature not by the impact of variation of ambient temperature.Tempeerature-constant air sampling distribution piping has sampling joint 4 near lower end, for connecting various gas analyzer, carries out analysing and processing to sample gas, and the internal chamber wall of the steel pipe 1 of inner liner polytetrafluoroethylene connects temperature sense and control gear.
Described temperature sense and control gear comprise heating tape 5, the temperature transducer 6 of affixed heating tape 5 and the temperature control box 7 that is connected with temperature transducer 6 signal.Tempeerature-constant air sampling distribution piping mounted inside has temperature sense and control gear, is specifically made up of heating tape 5, temperature transducer 6 and temp. controlling box 7.Heating tape 5 power supply, for exchanging 36V, converts alternating current 220V to interchange 36V by transformer.Temperature transducer 6 and heating tape 5 integration, maximizedly facilitate Installation and Debugging.During work, the temperature of induction is real-time transmitted to temp. controlling box 7 by temperature transducer 6, and Current Temperatures and set temperature compare by temp. controlling box 7 inside, thus controls heating-up temperature real-time stabilization on set temperature point.
Sampling joint 4 and various gas analyzer linkage section all have Insulation, prevent gas from condensing and damage various gas analyzer.
Through Tempeerature-constant air sampling distribution piping by the various gas analyzer of feeding harmless for sample gas, ensure that the accuracy of gas-monitoring data from source, the maximized damage reduced various gas analyzer.The perlite of the Tempeerature-constant air sampling distribution piping of this structure has effect sample gas being kept to constant temperature, avoids the impact of fluctuation on sample gas of ambient temperature, substantially increases the accuracy of gas-monitoring data.The distribution piping of Tempeerature-constant air sampling is simultaneously provided with the temperature sense and control gear that regulate line temperature, and energy is regulating and control line temperature in real time, by pipeline gas temperature stabilization on set temperature point.Easy for installation, compact structure, manufactures cheap feature.
Those skilled in the art should know; protection scheme of the present utility model is not limited only to the above embodiments; various permutation and combination and conversion can also be carried out on the basis of above-described embodiment; under the prerequisite without prejudice to the utility model spirit, the various conversion that the utility model carries out all are dropped in protection domain of the present utility model.
