Be arranged on due to heating arrangement in the groove of upper fixture block, with upper fixture block close contact, the heat that this heating arrangement provides promptly is delivered on fixture block, and upper fixture block is arranged on the air chamber pipe by screw, with air chamber pipe close contact, the heat of going up like this fixture block also is delivered on the air chamber pipe very soon, and this temperature that has just guaranteed the air chamber inside pipe wall can be controlled in certain scope, prevents that gas from forming condensation at the air chamber inside pipe wall.
Description of drawings
Below, illustrate in greater detail the utility model with reference to the embodiment that shows by accompanying drawing.The embodiment that should be emphasized that demonstration only is used for the example purpose, and should not be used for limiting protection domain of the present utility model.
Fig. 1 is the structural representation with optics air chamber pipe component of heating arrangement; With
Fig. 2 is the schematic cross-section with optics air chamber pipe component of heating arrangement.
Embodiment
Below in conjunction with the drawings and specific embodiments, a kind of air chamber pipe of using for the gas analysis optical detection that the utility model provides is described in detail.
As shown in the figure, in order clearly to realize the structure of embodiment of the present utility model, specific structure and device have been marked in the drawings, but this only needs for signal, be not intended to the utility model is limited in this ad hoc structure, device and environment, according to specific needs, those of ordinary skill in the art can adjust these devices and environment or revise, and the adjustment of carrying out or modification still are included in the scope of accompanying claim.
In the following description, a plurality of different aspects of the present utility model will be described, yet, for those skilled in the art, can only utilize more of the present utility model or entire infrastructure or flow process are implemented the utility model.For the definition of explaining, set forth specific number, configuration and order, but clearly, in the situation that do not have these specific detail can implement the utility model yet.In other cases,, in order not obscure the utility model, for some well-known features, will no longer be described in detail.
Fig. 1 is the structural representation with the gas analysis optics optics air chamber pipe component of heating arrangement, Fig. 2 is the schematic cross-section with optics air chamber pipe component of heating arrangement, as illustrated in fig. 1 and 2, optics air chamber pipe component comprises: pressing plate 1, heating arrangement 2, upper fixture block 3, air chamber pipe 4 and lower fixture block 5.
But, the utility model is not limited to this, the air chamber pipe also can otherwise be clamped between fixture block and lower fixture block, and upper fixture block and lower fixture block can not have the cambered surface that inwardly concaves or only have one of them to have cambered surface, as long as upper fixture block or lower fixture block can be fixed the air chamber pipe.
Because the cambered surface of upper fixture block 3 and lower fixture block 5 fully contacts with the outside surface of air chamber pipe 4, so can fully heat by the outside surface by 2 pairs of air chamber pipes 4 of heating arrangement in clamping air chamber pipe 4 stably, thereby improve the efficiency of heating surface and reduce thermal losses.
