Abstract
An optical platform for gas analysis comprises a gas chamber pipe, a light-emitting element and a photosensitive element, which is characterized in that: the light-emitting element is fixed in a gas chamber seat and the photosensitive element is fixed on the other gas chamber seat; the two gas chamber seats are respectively sleeved with the two ends of the gas chamber pipe. The utility model takes the gas chamber pipe as the installation reference, and only the two gas chamber seats are sleeved on the two ends of the gas chamber pipe so that the light-emitting element and the photosensitive element can align voluntarily, thereby improving the installation precision.
Description
Technical field
The utility model relates to the gas analysis optical table that is used for analytical gas.
Background technology
The gas analysis optical table is widely used in various occasions such as motor-vehicle tail-gas detection.The light that the light activated element that the primary structure of gas analysis optical table comprises the air chamber pipe, is positioned at the light-emitting component of air chamber Guan Yiduan and is positioned at the air chamber pipe other end, light-emitting component send projects on the light activated element through the air chamber pipe.Whether light-emitting component and light activated element align, and directly have influence on the measuring accuracy of gas analysis optical table.Yet in existing gas analysis optical table, neither one can help the reference for installation that aligns between light-emitting component and the light activated element, is difficult to guarantee that the optical axis of light-emitting component and light activated element is on same straight line.
The utility model content
The purpose of this utility model provides a kind of gas analysis optical table that is easy to guarantee light-emitting component and light activated element installation accuracy.
The utility model is achieved in that the gas analysis optical table comprises air chamber pipe, light-emitting component and light activated element, especially, light-emitting component is fixed in the air chamber base, and light activated element is fixed in another air chamber base, two air chamber bases respectively with the two ends socket of air chamber pipe.The utility model as reference for installation, as long as the two ends that two air chamber bases are enclosed within the air chamber pipe just can make light-emitting component and light activated element align voluntarily, has improved installation accuracy with the air chamber pipe thus.
The utility model has the advantages that promptly having improved installation accuracy is convenient to again install, and has improved the measuring accuracy of gas analysis optical table greatly.
Description of drawings
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of embodiment 2.
Embodiment
Referring to Fig. 1, the gas analysis optical table comprises air chamber pipe 1, light-emitting component 2 and light activated element 3.Light-emitting component 2 is fixed in the air chamber base 4, and light activated element 3 is fixed in another air chamber base 5.The air chamber base 4 at light-emitting component place offers jack 4a, the light shaft coaxle of the axis of jack 4a and light-emitting component 2.One end of air chamber pipe 1 is enclosed within the jack 4a and with O-ring seal 6 and seals.The axis of air chamber pipe 1 is coaxial with the axis of jack 4a.The air chamber base 5 at light activated element place offers jack 5a, and light activated element 3 is positioned on the axis of jack 5a.The other end of air chamber pipe 1 is enclosed within the jack 5a and with O-ring seal 7 and seals.The axis of air chamber pipe 1 is coaxial with the axis of jack 5a.Two air chamber bases 4,5 global formation respectively have valve 4b, 5b, are used to connect tracheae.Detected gas enters air chamber pipe 1 through the valve of one of them air chamber base, and the valve from another air chamber base flows out again.
As further improvement, present embodiment also is equipped with temperature-measuring element 8 and/or pressure measuring element 9 in air chamber base 5.Facilitate air pressure and/or the temperature measured in the air chamber pipe 1 like this.Temperature-measuring element 8 and pressure measuring element 9 can be installed in any one air chamber base, perhaps in two air chamber bases temperature-measuring element and/or pressure measuring element are installed all.The control circuit relevant with light-emitting component 2, light activated element 3, temperature-measuring element 8, pressure measuring element 9 also in the lump aggregate erection in air chamber base 4,5.
Referring to Fig. 2, present embodiment is mainly that with the difference of embodiment 1 connected mode of air chamber base and air chamber pipe is different.In the present embodiment, air chamber base 4 global formations at light-emitting component 2 places have intubate 4c, the light shaft coaxle of the axis of intubate 4c and light-emitting component 2.Intubate 4c inserts an end of air chamber pipe 1.The axis of air chamber pipe 1 is coaxial with the axis of intubate 4c.Air chamber base 5 global formations at light activated element 3 places have intubate 5c, and light activated element 3 is positioned on the axis of intubate 5c.Intubate 5c inserts the other end of air chamber pipe 1.The axis of air chamber pipe 1 is coaxial with the axis of intubate 5c.Other structures of present embodiment are identical with embodiment 1.
Claims (2)
1. a gas analysis optical table comprises air chamber pipe, light-emitting component and light activated element, it is characterized in that: light-emitting component is fixed in the air chamber base, and light activated element is fixed in another air chamber base, two air chamber bases respectively with the two ends socket of air chamber pipe.
2. gas analysis optical table as claimed in claim 1 is characterized in that: be provided with temperature-measuring element and/or pressure measuring element in an air chamber base at least therein.
