Abstract
The utility model provides a new-type flammable nozzle of the gas chromatograph hydrogen blaze detector which comprises a hollow quartz pipe and a hollow mental cap and is characterized in that the external wall of the quartz pipe head sticks out and the corresponding place of the internal wall of the mental wall has a hollow inside; the mental cap is arranged at the head of the quartz pipe and the internal concave of internal wall of the mental cap is closely cooperated and stuck with the bulge of the external wall of the quartz pipe to make the quartz pipe combine with the mental cap. The utility model has the advantages of that the quartz pipe adopts the machine to be connected with the mental cap and the head of the quartz pipe has a bulge which makes the mental cap to be directly covered and checked so as to avoid the rupture caused by the stress of the high-temperature glue and be convenient to be used and maintained to have a long service time and thereby the stability and reliability of the utility model can be greatly improved.
Description
Affiliated technical field
The utility model relates to a kind of burner noz(zle) structure, especially the burner noz(zle) new construction of gas chromatograph hydrogen flame detector.
Background technology
The burner noz(zle) of the gas chromatograph hydrogen flame detector of prior art all is made up of quartz ampoule and metal cap, and the method that the employing high-temp glue is connected is with the two combination.Because high-temp glue deforms and quartz ampoule is produced stress in the high-temp combustion, therefore the quartz ampoule head is easily broken along the metal cap lower edge in the high temperature barbecue, and in the working service process also frangibility, serviceable life is low.
Summary of the invention
The utility model provides a kind of burner noz(zle) new construction of gas chromatograph hydrogen flame detector, goal of the invention of the present utility model is, overcome the prior art shortcoming, adopt new quartz ampoule and metal cap syndeton, the breakage problem of having avoided high-temp glue stress to be caused, easy to use with safeguard that increased serviceable life, and the stability and the reliability of instrument increase substantially.
The technical scheme that its technical matters that solves the utility model adopts is:
The burner noz(zle) new construction of gas chromatograph hydrogen flame detector, comprise hollow quartz tube and hollow metal cap, it is characterized in that: quartz ampoule head outer wall has to outer lug, metal cap inwall relevant position has indent, metal cap is sheathed on the quartz ampoule head, and the indent of metal cap inwall closely cooperates blocking and quartz ampoule is combined with metal cap with the projection of quartz ampoule outer wall.
The projection of above-mentioned quartz ampoule head outer wall is that quartz ampoule head outer wall has the protruding wall of ring-type, and the metal cap inwall has the ring-type inner groovy, and the ring-type inner groovy on the metal cap inwall cooperates blocking with the protruding wall of the ring-type of quartz ampoule outer wall.
The beneficial effects of the utility model are, quartz ampoule and metal cap adopt mechanical connection, the quartz ampoule head has projection, metal cap directly puts chucking, avoided like this high-temp glue stress breakage problem extremely, easy to use with safeguard that increased serviceable life, and the stability and the reliability of instrument increase substantially.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural drawing of the present utility model.
Embodiment
In Fig. 1, quartz ampoule 1 is a hollow quartz tube, thermal-flame is from the head ejection of quartz ampoule 1, metal cap 2 is thin metal cylinder of a hollow and the head that is sheathed on quartz ampoule 1, quartz ampoule 1 head is provided with the protruding wall 11 of ring-type, and metal cap 2 inwalls have annular recess 21, after metal cap 2 is set in quartz ampoule 1 head, the blocking that cooperatively interacts of the protruding wall of ring-type 11 and annular recess 21, quartz ampoule 1 is with metal cap 2 formation mechanical connections and combine.
Claims (2)
1, the burner noz(zle) new construction of gas chromatograph hydrogen flame detector, comprise hollow quartz tube and hollow metal cap, it is characterized in that: quartz ampoule head outer wall has to outer lug, metal cap inwall relevant position has indent, metal cap is sheathed on the quartz ampoule head, and the indent of metal cap inwall closely cooperates blocking and quartz ampoule is combined with metal cap with the projection of quartz ampoule outer wall.
2, the burner noz(zle) new construction of gas chromatograph hydrogen flame detector as claimed in claim 1, it is characterized in that: quartz ampoule head outer wall has the protruding wall of ring-type, the metal cap inwall has the ring-type inner groovy, and the ring-type inner groovy on the metal cap inwall cooperates blocking with the protruding wall of the ring-type of quartz ampoule outer wall.
