Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
The utility model provides a sampling needle bubble detection device, as shown in fig. 1 to 3, including xarm 8, be provided with bubble detection sensor 4, sampling needle 1 and suction appearance pipe 6 on the xarm 8, sampling needle 1 and suction appearance pipe 6 adopt glass fiber hyaline tube 3 to connect between, are provided with on the bubble detection sensor 4 and are used for wearing to establish glass fiber hyaline tube 3's circular inspection hole 13.
The utility model discloses a sample needle bubble detection device adopts the photoelectricity to directly detect the bubble to the drawback of pressure detection bubble mode, places the glass fiber hyaline tube 3 of connecting on sample needle 1 on bubble detection sensor 4, directly detects the bubble in the pipeline through adopting the photoelectricity principle, can effectively avoid the interference of pipeline internal pressure to make bubble detection device more stable, accurate.
The utility model relates to an in the embodiment, because glass fiber is difficult to react with being inhaled solution, is difficult to glue and hangs, remain and is inhaled solution to the detection light beam of bubble detection sensor 4 transmission easily passes the pipeline, can be accurate detect out to have the bubble in the pipeline.
Further, the bubble detection sensor 4 is provided with a groove 12 for fixing a light emitting end and a light receiving end on the inner walls of the two sides of the circular detection hole 13, the outer wall of the glass fiber transparent tube 3 is tightly attached to the joint of the groove 12 and the circular detection hole 13, the bubble detection sensor 4 irradiates the glass fiber transparent tube 3 through a light emitting end emitting light beam, and the light receiving end of the bubble detection sensor 4 is detected.
In order to facilitate the connection between the sampling needle 1 and the cross arm 8, a fixing sleeve 9 can be added between the sampling needle 1 and the cross arm 8, and the difficulty in processing the cross arm 8 can be reduced by fixing the sampling needle 1 on the cross arm 8 through the fixing sleeve 9.
Preferably, the glass fiber transparent tube 3 is in threaded connection with the sampling needle 1 and the sample suction tube 6 through joints respectively, so that the sampling needle 1, the glass fiber transparent tube 3 and the sample suction tube 6 form a complete passage.
The utility model discloses an in the embodiment, the transmission of liquid between sample suction pipe 6, glass fiber hyaline tube 3 and sampling needle 1 is through the drive of sample suction pump 15, and is concrete, and sample suction pipe 6 passes through stereoplasm screwed joint fixed connection with sample suction pump 15.
