Abstract
The utility model relates in oil kryoscope the visual cooling bath used, the visual cooling bath used in this oil kryoscope comprises cell body, entrance, outlet, two condensation point sleeve pipes, cell body is the clear glass cell body with vacuum heat-insulating layer, seal groove lid covers on cell body, and cell body entrance and exit all passes from vacuum heat-insulating layer; Two condensation point sleeve pipes are transparent glass tube, and are all integrally formed with cell body bottom surface; The outer wall of cell body is bonded with rectangular magnifier, and magnifier is corresponding with the middle and lower part of condensation point sleeve pipe.When the utility model carries out oil determination of freezing point, the test tube installing laboratory sample puts into condensation point sleeve pipe, install thermometer after, loading or unloading operation need not be carried out to test tube again, observe the flow condition of in vitro sample by magnifier.
Description
Technical field:
The utility model relates to a kind of proving installation of petroleum products, what be specifically related to is the visual cooling bath used in oil kryoscope.
Background technology:
Existing oil kryoscope comprises cabinet, the cooling bath be connected with cabinet, to provide the refrigerating plant of heat transferring medium for cooling bath, turned over by cooling bath and turn 90 degrees and the wheelwork that can reset.When carrying out determination of freezing point to oil, the condensation point test tube that test sample is housed is placed in cooling bath condensation point sleeve pipe, after installing thermometer, according to petroleum industry condensation point testing standard, is down to after more than estimation condensation point 8 DEG C until specimen temperature, needs every 2 DEG C to observe once.Because test tube is placed in cooling bath, cannot observe directly test tube and thermometer outside cooling bath, the method for observation is that after taking out test tube inclination, whether judgement sample flows.When condensation point test tube tilts 90 degree, maximum temperature when sample 5s does not flow is considered as condensation point temperature, because needs pick and place test tube repeatedly, add thermal history and the shear history of laboratory sample, affect the accuracy of determination of freezing point, in addition, repeatedly manually pick and place tube manipulation cumbersome.
Summary of the invention:
The purpose of this utility model is to provide in oil kryoscope the visual cooling bath used, and it is for solving in existing oil kryoscope experimentation as observing the problem needing repeatedly to pick and place test tube from cooling bath.
The utility model solves the technical scheme that its technical matters adopts: the visual cooling bath used in this oil kryoscope comprises cell body, entrance, outlet, two condensation point sleeve pipes, cell body is the clear glass cell body with vacuum heat-insulating layer, seal groove lid covers on cell body, and cell body entrance and exit all passes from vacuum heat-insulating layer; Two condensation point sleeve pipes are transparent glass tube, and are all integrally formed with cell body bottom surface; The outer wall of cell body is bonded with rectangular magnifier, and magnifier is corresponding with the middle and lower part of condensation point sleeve pipe.
The utility model has following beneficial effect:
When the utility model carries out oil determination of freezing point, the test tube installing laboratory sample puts into sleeve pipe, install thermometer after, loading or unloading operation need not be carried out to test tube again.Specimen temperature is forwarded to visual cooling bath, is observed the flow condition of in vitro sample by magnifier after being down to and estimating more than condensation point 8 DEG C.When cooling bath 90-degree rotation, in vitro sample 5s does not flow, and just reads the condensation point temperature of sample by thermometer.Instrument measuring precision is high, simple to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 cell body, 2 entrances, 3 outlets, 4 condensation point sleeve pipes, 5 vacuum heat-insulating layers, 6 seal groove lids, 7 magnifieres.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, the visual cooling bath used in this oil kryoscope comprises cell body 1, entrance 2, outlet 3, two condensation point sleeve pipes 4, and cell body 1, for having the clear glass cell body of vacuum heat-insulating layer 5, utilizes vacuum heat-insulating layer 5 pairs of cell bodies 1 to be incubated; Seal groove lid 6 covers on cell body 1, and cell body entrance 2 and outlet 3 are all passed from vacuum heat-insulating layer 5, and when entrance 2 and outlet 3 are for measuring, cold-producing medium enters cell body and the port leaving cell body; Two condensation point sleeve pipes 4 are transparent glass tube, and are all integrally formed with cell body 1 bottom surface, and condensation point sleeve pipe 4 is loaded with the test tube of test sample for placing; The outer wall of cell body 1 is bonded with rectangular magnifier 7, magnifier 7 is corresponding with the middle and lower part of condensation point sleeve pipe 4, the test tube being loaded with test sample is put in condensation point sleeve pipe 4, sample to be tested wherein is just in time in the middle and lower part of condensation point sleeve pipe 4, when test tube 90 degree rotation reciprocal along with cooling bath, clearly can be observed the state of in vitro sample by magnifier 7, and be convenient to reading.
When the utility model carries out oil determination of freezing point, first with cabinet, refrigerating plant, wheelwork couples together, for replacing original opaque cooling bath, test sample is placed in test tube, test tube is placed in the condensation point sleeve pipe 4 of cooling bath, thermometer is inserted in test tube, the encirclement of cooled dose of condensation point sleeve pipe 4, to realize cold-producing medium, sample invisible spectro in condensation point sleeve pipe 4 is cooled, when test tube 90 degree rotation reciprocal along with cooling bath, directly can be observed test tube by transparent cooling bath and condensation point sleeve pipe 4, careful observation can be carried out to the flowing property of in vitro sample by magnifier 7 simultaneously, also can read the reading of thermometer simultaneously, and repeatedly need not pick and place test tube, simple to operate, improve the accuracy of measurement result.
