Abstract
The utility model discloses a bobble release accurate positioning frame for liquid viscosity coefficient survey experiments, it relates to college physics laboratory glassware technical field, it contains stand pipe, stand pipe V type mouth, panel, the lantern ring, sight vane, and the internal surface of stand pipe is the face of cylinder, and the internal surface of stand pipe V type mouth is the circular conical surface, and the common axis of stand pipe and stand pipe V type mouth is on panel and the common axle center of cover ring sum, and the excavation has the circular shape sight vane on the panel, the utility model discloses when the experiment, through the effect of stand pipe V type mouth and stand pipe, make the bobble ability fall from the axis of liquid column accurately to satisfied experiment principle improves the experiment precision to the requirement of bobble whereabouts position.
Description
Technical field
The utility model relates to coefficient of viscosity determination experiment bead and discharges accurate locating rack, belongs to Experiment of College Physics Instrument technology field.
Background technology
In the coefficient of viscosity determination experiment of College Physics, in order to indirectly realize the extensive property of liquid level, fall, in practical operation from the axis of fluid column after requiring bead to be released, hand-held release be difficult to accurately finds axis, and bead contact liquid level also may produce drift and off-axis.
Utility model content
For the problems referred to above, the technical problems to be solved in the utility model is to provide coefficient of viscosity determination experiment bead and discharges accurate locating rack.
Coefficient of viscosity determination experiment bead of the present utility model discharges accurate locating rack, it comprises guide pipe, guide pipe V-type mouth, panel, the collar, sight vane, the inside surface of guide pipe is the face of cylinder, the inside surface of guide pipe V-type mouth is circular conical surface, at panel and the collar and common axle in the heart, on panel, excavation has circular sight vane for the common axis line of guide pipe and guide pipe V-type mouth.
As preferably, the internal diameter of the described collar is identical with the external diameter of experimental glass pipe.
As preferably, the internal diameter of described guide pipe is slightly larger than the small ball's diameter.
The beneficial effects of the utility model are: during coefficient of viscosity determination experiment, by the effect of guide pipe V-type mouth and guide pipe, bead can be fallen from the axis of fluid column accurately, thus meet the requirement of experimental principle to bead drop-off positions, improve experimental precision.
Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structure longitudinal profile of the present utility model schematic diagram, and Fig. 2 is structure vertical view of the present utility model, and Fig. 3 is experimental provision schematic diagram.
In figure: 1-guide pipe, 2-guide pipe V-type mouth, 3-panel, the 4-collar, 5-sight vane, 6-experimental glass pipe, 7-experimental liquid.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by the specific embodiment shown in accompanying drawing, the utility model is described.But should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, this embodiment is by the following technical solutions: it comprises guide pipe 1, guide pipe V-type mouth 2, panel 3, the collar 4, sight vane 5, the inside surface of guide pipe 1 is the face of cylinder, the inside surface of guide pipe V-type mouth 2 is circular conical surfaces, at panel 3 and the collar 4 and common axle in the heart, on panel 3, excavation has circular sight vane 5 for the common axis line of guide pipe 1 and guide pipe V-type mouth 2.
Further, the internal diameter of the described collar 4 is identical with the external diameter of experimental glass pipe.
Further, the internal diameter of described guide pipe 1 is slightly larger than the small ball's diameter.
The principle of work of this embodiment is: discharged above guide pipe V-type mouth 2 by bead during experiment, little ball warp guide pipe V-type mouth 2 enters guide pipe 1, because the axis of guide pipe 1 is in the axle center of panel 3, the internal diameter of the collar 4 is identical with the external diameter of experimental glass pipe makes the collar 4 and experimental glass pipe close contact, thus the internal diameter of guide pipe 1 makes the gap of bead and guide pipe 1 inwall very little slightly greatly than the small ball's diameter, bead is strictly fallen along the axis of fluid column, sight vane 5 makes experimental liquid surface lead to air thus keep the pressure on experimental liquid surface to be atmospheric pressure.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
