After the device is used, measurement results are more accurate and effective.
Description
Technical field
The utility model is specifically related to a kind of scintillation pick-up unit of open flash point analyzer.
Background technology
The at present domestic open flash point detection assay appearance overwhelming majority adopts the detection method that detects principle based on high-field electrode.High-field electrode detects the sensor method and has characteristics such as simple in structure, cheap, that realization is easy.But existing in the market open flash point electrode inspector has very big defective: very gentle even when only producing very little flare when tested oil sample oil gas scintillation, will detect less than, cause testing result inaccurate.
The utility model content
The purpose of the utility model is to solve the low defective of scintillation pick-up unit detection sensitivity of existing open flash point analyzer, provides a kind of detection sensitivity high, adopts the scintillation pick-up unit of the open flash point analyzer of point discharge principle design.
The utility model is realized through following technical scheme:
It is a kind of scintillation pick-up unit of open flash point analyzer; It is characterized in that comprising electrode suppor; Be fixed with the electrode pair that two electrodes are formed on the electrode suppor, the lower end of two electrodes is connected with detection ring, and said detection ring is made up of ring in detecting and detection outer shroud; An electrode is connected with the interior ring of detection, and another electrode is connected with the detection outer shroud.
A preferred version as the utility model: the point discharge body of the surperficial protrusion that evenly distributes of ring and detection outer shroud in detecting.
A preferred version as the utility model: the point discharge body is a triangle.
The ultimate principle of the utility model: according to the point discharge principle, electric charge can gather the point discharge body in a large number, improves detection ring sensitivity greatly.On electrode pair, add certain voltage, when scintillation appears in tested oil sample, can produce charged ion, between both positive and negative polarity, form the conducting medium layer, the detection ring circuit forms loop signal, gets into single-chip microcomputer and produces Interrupt Process.Judge the appearance of scintillation thus.Thereby reach the purpose of highly sensitive mensuration scintillation.
The utlity model has advantage simple in structure, that detection sensitivity is high.Use the utility model to make measurement result more accurate and effective.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A cut-open view of Fig. 1.
Shown in figure: 1. electrode suppor; 2-1. electrode; The 2-2 electrode; 3. detection ring; 3-1. ring in detecting; 3-2. detection outer shroud; 4. lead; 5. point discharge body
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further elaboration.
Can know by Fig. 1: on electrode suppor 1 (processing), fixed the electrode pair that electrode 2-1 and electrode 2-2 form by insulating material; Lower end at electrode pair becomes being fixed on the detection ring 3 of an angle of 90 degrees; Detection ring comprises detection interior ring 3-1 and detects outer shroud 3-2, will detect the interior 3-1 of ring, detect outer shroud 3-2 placement evenly, and electrode 2-1 is fixed on the interior ring of the detection 3-1; Electrode 2-2 is fixed on and detects on the outer shroud 3-2, with lead 4 electrode pair is inserted testing circuit.
Can know that like Fig. 2 spread all over leg-of-mutton point discharge body 5 on ring 3-1, the detection outer shroud 3-2 in detecting, according to the point discharge principle, electric charge can gather point discharge body 5 in a large number, improves detection ring 3 sensitivity greatly.On electrode pair, add certain voltage, testing circuit forms loop signal when scintillation appears in tested oil sample, judges the appearance of scintillation thus.Thereby reach the purpose of highly sensitive mensuration scintillation, make measurement result more accurate and effective.
