Description
Technical field
The utility model relates to a kind of detection devices.
Background technique
In chemical production field, the quality of product such as content etc. is the life of product, and the content of product, especially gas
The detection of the purity of body or liquid needs to carry out analysis detection to product.
Currently, conventional method is, in production scene, is sampled, be sent in detection and analysis by the sample tap of equipment
The heart is analyzed by instrument such as chromatography or using chemical method.
Above-mentioned method, it is clear that have the defects that many:
(1) at the scene due to product sampling, such as temperature of environmental condition locating for sample etc., with the incomplete phase of analysis center
Together, for fluid sample, high-boiling-point impurity meeting condensation therein leads to the sample for being sent into analysis instrument and former sampling
The content of sample has differences, and (2) sample, especially fluid sample, containing the particle accidentally brought into equipment, which is brought into
Analysis instrument, such as chromatography will lead to chromatographic column sensitivity decrease, (3) more importantly, cannot reflect in time production in product
Instantaneous mass.
Utility model content
The purpose of the utility model is to provide a kind of chemical liquid On-line Product detection devices, to overcome the prior art to exist
Defect.
The constant current case includes cabinet and overflow plate, the two sides and bottom of the overflow plate in the cabinet phase
Wall connection, the side of overflow plate are sample spill cavity, and the other side is sample constant current chamber, and the top of the overflow plate is equipped with overflow
Mouthful, the probe tube is connected with the sample inlet that the sample constant current chamber side is arranged in, and the one of the sample feeding pipe
It holds and is connected with the outlet of the sample constant current chamber in sample constant current bottom of chamber portion；
The bottom of the sample spill cavity is equipped with bypass outlet.
The beneficial effects of the utility model are: structure is simple, convenient for operation, can be monitored on-line at any time, and can
Ensure that the trace impurity in sample enters analysis instrument, it can be ensured that the consistency of test sample and product.
