Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 shows the displacement sensing apparatus structural representation according to first embodiment of the invention;
Fig. 2 shows the displacement sensing apparatus structural representation according to second embodiment of the invention;
Fig. 3 shows the displacement sensing apparatus structural representation according to third embodiment of the invention.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Fig. 1 shows the displacement sensing apparatus according to first embodiment of the invention, comprising: vortex tube 10 and displacement transducer 20, as shown in Figure 1, the cold air end of vortex tube is connected with the inlet end of displacement transducer.
To be input to from 0.4～0.7Mpa pressurized air at air pressure station in the vortex tube 10, and by the cold air end of vortex tube, produce the very low cold air of temperature, the big I of the temperature of cold airflow and flow is controlled by the valve 30 of regulating vortex tube hot gas end.The cold air end is connected to the inlet end of displacement transducer 20, plays the effect of cooling displacement transducer.Adopt the displacement sensing apparatus good cooling results of this structure, and can also pass through valve 30 flexible cryogenic temperatures, can effectively reduce the environment temperature of displacement transducer, guaranteed the precision and the stability of displacement transducer.
Fig. 2 shows the displacement sensing apparatus structural representation according to second embodiment of the invention, as shown in Figure 2, it is different that vortex tube and the connected mode of displacement transducer are different from first embodiment, in the present embodiment, the cold air end of vortex tube links to each other with a pipeline, be connected with a plurality of displacement transducers on the pipeline, the quantity of displacement transducer can be provided with according to actual needs.
Pressurized air is from the draft tube input of vortex tube, the cold airflow that flows out through the cold air end of vortex tube enters the pipeline that is connected, flow into displacement transducer through the inlet end that is connected the displacement transducer on the pipeline then, thereby can regulate the temperature of a plurality of displacement transducers by using a vortex tube.The structure of this one-to-many of present embodiment is fit to the use occasion of multidigit displacement sensor very much, can reduce the thermoregulator cost of displacement transducer.
Fig. 3 shows the displacement sensing apparatus structural representation according to third embodiment of the invention, and as shown in Figure 3, in the present embodiment, vortex tube and displacement transducer all are a plurality of, and quantity equates.The inlet end of all vortex tubes links together by pipeline, and the cold air end of each vortex tube all is connected with the inlet end of a displacement transducer.
Pressurized air at first enters a pipeline, and the inlet end by vortex tube enters the vortex tube that is connected with pipeline then, and the cold airflow that flows out through the cold air end of vortex tube flows into displacement transducer by the inlet end of displacement transducer again.Thereby can reduce the environment temperature of displacement transducer effectively, improve the precision and the stability of displacement sensing apparatus.
In addition, the structure of this displacement sensing device can also have various changes and variation, for example, on the basis of the structure of the 3rd embodiment, between the inlet end of the cold air end of vortex tube and displacement transducer, can also increase pipeline, the inlet end of the inlet end of the cold air end of all vortex tubes and all displacement transducers all is connected on the same pipeline, adopts this structure can be provided with according to actual needs so that the quantity of vortex tube in the displacement sensing apparatus and displacement transducer is unrestricted.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
