Its sample of spectrometer can be measured directly without pretreatment, and measurement method has transmission, reflection and diffusing reflection diversified forms, be suitble to measurement
The sample of the forms such as liquid, solid and pulpous state, thus it is widely used.
For on-line checking of liquid during pipeline transportation, is mostly sampled, limited hand-held using the mode of flow cell
Application of the spectrometer in liquid on-line detection；Another aspect liquid flowing when, especially flowing velocity quickly when can be in liquid
A large amount of bubbles are generated in body, influence the accuracy of measurement result.
Summary of the invention
In order to overcome drawbacks described above, the present invention discloses a kind of fluid sample sampler suitable for pipeline spectra collection,
It mainly include that flange, detection sleeve, sampler and reflecting plate, sampler are fixed on the inner wall of flange, detection sleeve passes through method
Orchid is inserted in sampler, and reflecting plate is fixed in the outer surface of the sampler；It is characterized by:
Detection sleeve is the bolt with hollow sleeve, for accommodating spectral instrument probe, carries out spectral information acquisition；
The sampler face ontology A has fluid collection chamber, test chamber, sample holes, current limiting plate, slit, overflow hole, liquid outlet and detection window
Mouthful, the face B has opening；Current limiting plate is covered at sample holes upper opening, and the flow of sample holes is entered for limiting liquid；Slit
Connection sample holes and fluid collection chamber, detection window are located in test chamber, with opening coaxial communication；
Liquid is flowed by sample holes in pipeline, is entered fluid collection chamber by slit, is then flowed into test chamber by overflow hole, liquid level reaches
Sampler is flowed out at overflow hole, while respectively sampler is discharged in fluid collection chamber and test chamber bottom hydrops by liquid outlet；
When spectra collection, it will test probe first and be against on detection window across detection sleeve, the light for sending of popping one's head in is through detection
Sample in window and test chamber enters detection probe by baffle reflection, realizes spectral information acquisition.
Narrow-gap channel wide 5mm, high 0.6mm.
Liquid outlet upper opening is the circular hole of diameter 0.6mm, and lower part uses the shape of inverted funnel；Be conducive to fluid collection chamber and inspection
It surveys chamber bottom liquid stream to go out, avoids the formation of dead sample.
Beneficial effect is mainly shown as: by the design of current limiting plate, slit and fluid collection chamber, being effectively eliminated into liquid
Bubble, improves the accuracy of spectral detection, while realizing hand-held spectrometer and detecting for liquid on-line.
