Description
Technical field
The utility model relates to a kind of proportioning device, especially a kind of optics proportioning device.
Background technology
At present, the most optics quantitative manner that adopt of the quantitative system in the water quality testing meter.Optics quantitative manner ubiquity is simple in structure, processing is convenient, but the not high characteristics of quantitative accuracy.The schematic diagram of optics quantitative manner is seen Fig. 1, because the architectural characteristic of itself, inevitably there is an absolute error when causing it to use, the maximal value of this absolute error is Δ V=(D+h) * S, wherein D is the height of the light that sees through quantity tube, i.e. the width of the diameter of unthreaded hole or slit, and h is the height of concave meniscus, for fixed light source with determine liquid to be got, (D+h) size is determined; S is the sectional area of light path upper glass pipe.When the quantitative liquor capacity of needs was V, each relative error maximal value that quantitatively produces was δ=Δ V/V*100%.V one regularly, the unique method that reduces δ reduces absolute error Δ V exactly, and the method that reduces Δ V has two kinds, the one, reduce the value of (D+h), the 2nd, the size that reduces S namely reduces the diameter of glass tube.
Traditional quantity tube is because the glass tube even thickness, then need quantitative liquor capacity V can be expressed as V=H*S, wherein H is for needing the height of quantitative solution, when when reducing S and reduce absolute error Δ V, just need to improve the value of H, namely used glass tube need be made elongate, and in the reality, because it is dexterous that the instrument and equipment global design is tending towards, the quantitative glass tube length of its optics does not allow oversize.
Summary of the invention
The utility model purpose is: a kind of accuracy height is provided, and can reduces the optics proportioning device of error.
The technical solution of the utility model is: a kind of optics proportioning device, comprise glass quantity tube and Photoelectric Detection piece, described glass quantity tube comprises straight-through glass pipe and spherical glass pipe, the diameter of described spherical glass pipe is greater than the diameter of described straight-through glass pipe, described spherical glass pipe top is connected with described straight-through glass pipe, and described Photoelectric Detection piece is positioned on the described straight-through glass tube wall.
Preferably, described spherical glass pipe has more than 1 or 2, when described spherical glass pipe has 2 when above, is communicated with by described straight-through glass pipe between the adjacent described spherical glass pipe.
Preferably, be provided with the solution gateway bottom the described glass quantity tube.
The principle that the utility model uses is as follows: quantitative relative error of the present utility model is the * S/V*100% of δ=(D+h) to the maximum, determine at required volumetric soiutions volume V, (D+h) under the situation that can not reduce again, can be by reducing S, the diameter that namely enlarge spherical glass pipe diameter, reduces the straight-through glass pipe reduces quantitative error, and the length that no longer needs to increase glass tube is kept the constant of V.Under this design proposal, only need to finely tune the long-pending high precision of carrying out of getting liquid at the height of straight-through glass tube portion by regulating the Photoelectric Detection piece by a small margin.
The utility model has the advantages that:
1. reduce quantitative error by the diameter that reduces straight-through glass pipe on the Photoelectric Detection piece.
2. by the design of spherical glass pipe, avoid in the practical application because increasing the inconvenience that quantity tube length is brought.
3. at the height of straight-through glass tube portion liquor capacity is carried out the high precision fine setting by fine setting Photoelectric Detection piece.
4. be applied to have higher precision than common optics proportioning device in the solution quantitative system of water quality detection.
