Abstract
The utility model relates to a vertical tube type glass capillary tube caplastometer. The utility model is characterized in that the outer wall of the utility model is provided with a graduation line, four to five spherical cavities with different volumes are discontinuously arranged below a straight-shaped glass tube and on the upper part of the graduation line, and capillary tubes are arranged below the cavities; straight tubes which are connected with the capillary tubes are arranged below the capillary tubes, and the straight tubes are better metal tubes; the spherical cavities, the capillary tubes, and upper and lower parts of the straight tubes have the same axial cord. The utility model is convenient to be cleaned and automatically sampling, and has wide determinable viscosity ranges.
Description
Technical field the utility model relates to a kind of viscosity meter.
Background technology is present, is used to measure the viscosity meter of petroleum products kinematic viscosity, and commonly used is viscosity meters such as Pin Shi, Ubbelohde.Because its U-shaped pipe one side has bigger diameter of Spherical Volume, thereby easy cleaning not, also make sample introduction be difficult to robotization simultaneously.
Summary of the invention the utility model top is a straight shape glass tube, is provided with the spherical hollow space that 4-5 volume size do not wait below it discontinuously, and their bottom is the kapillary with certain-length.Be provided with coupled straight tube below this kapillary, it can be glass tube, preferably metal tube.Each spherical hollow space of above-mentioned viscosity meter, kapillary reach straight-tube portion up and down, and their axis is a same axis.On this viscosity meter outer wall, be provided with scale mark in addition.
During use this viscosity meter is placed on the interior support of thermostatic bath, make it in vertical state, kapillary one side is positioned at the bottom, and its end tip cutting is in sample bottle.This viscosity meter upper end can link to each other with generation means for applying negative interface.So the tested petroleum products in the sample bottle then enters bottom straight tube, kapillary and diameter of Spherical Volume from bottom to top successively, disconnect then and being connected of negative pressure device, communicate with atmosphere on making viscosity meter.So tested oil product just flows downward under action of gravity automatically, the time of record oil product liquid level from the kapillary high scale to following scale can calculate the viscosity of this tested oil product according to formula.
The utility model has following advantage compared to existing technology:
1, because self structure determines that be convenient to clean, the while also is convenient to auto injection.
2, the range of viscosities broad that can measure of the utility model, a viscosity meter can replace several viscosity meters in the past to use, and therefore can save the equipment investment expense.
3, test speed is fast.
Description of drawings:
Fig. 1 is that the utility model master looks diagrammatic cross-section.
Fig. 2 is the utility model schematic top plan view.
Embodiment is in the synoptic diagram of straight pipe type glass capillary tube viscometer illustrated in figures 1 and 2, straight shape glass tube bottom is provided with the spherical hollow space 1 that 4 volume size do not wait discontinuously, their bottom is provided with kapillary 2, is provided with coupled metal tube 3 below the kapillary.Above-mentioned spherical hollow space, kapillary and metal tube part, their axis are same axis.On the outer wall of this viscosity meter, be provided with scale mark 4 in addition.
Claims (2)
1, a kind of straight pipe type glass capillary tube viscometer, it is characterized in that: outer wall is provided with and is provided with the spherical hollow space that 4-5 volume size do not wait discontinuously below the straight shape glass tube in top of scale mark, their bottom is provided with kapillary, below this kapillary, be provided with coupled straight tube, above-mentioned each spherical hollow space, kapillary reach straight-tube portion up and down, and their axis is a same axis.
2, straight pipe type glass capillary tube viscometer according to claim 1 is characterized in that: the straight tube below the kapillary is a metal tube.
