Abstract
The utility model relates to a liquid sampler. A hollow rubber ball is sheathed on the top of a glass tube, a small hole is arranged on the tube wall of the upper part of the glass tube, and the glass tube under the small hole is marked with scales. The composition of a sample sampled by the utility model is identical with the actual composition of each layer of the liquid product, so the accuracy of the inspection result of the liquid product is guaranteed, and the inspection quality is improved greatly.
Description
The utility model belongs to the fluid sampling device technical field.
During to the fluid product pick test, the representativeness of sample how will be directly connected to assay accurately whether.Whether sample the representative version that then depends on the sampler of using to a great extent.At present, widely used liquid sampler is the glass tubular structure when the quality of tracer liquid product, shown in subsequent figures 1.Its underpart is a tapered tube, and the middle part is a pipe, top pipe spherical in shape, top end opening.Earlier sampler is inserted to liquid bottom during sampling, after seal top end opening and propose sampler.The liquid of retaining in the sampler is promptly as institute's sample thief.The deficiency that has following two aspects with this sampler sampling: the one, the lower taper bore is less, and the ratio of the top layer liquid of being got is less than actual ratio; The 2nd, when sampler promoted, owing to lose the pressure of outside liquid gradually, in the sampler can part run off corresponding to the liquid of fluid product bottom in the bottom, and the ratio that causes the bottom liquid got is less than actual ratio.And often there is difference more or less in the composition of fluid product top layer, bottom liquid and center section liquid, and mostly be the impurity enriched district, therefore, relatively poor with the sample representativeness that above-mentioned sampler is got, thus influenced the accuracy of fluid product assay.
The purpose of this utility model is to provide a kind of institute sample thief to constitute and the identical liquid sampler of the actual formation of product, to improve the accuracy of fluid product assay.
For achieving the above object, the technical scheme that the utility model adopted is, is set with hollow rubber ball at the top of glass tube, has aperture on the tube wall of glass tube top, and aperture is marked with scale with the glass tube of lower part.
This practical advantage is that the formation of its sample thief is identical with the actual formation of each aspect of fluid product, and promptly institute's sample thief has good representativeness, thereby can guarantee the accuracy of fluid product assay, improves quality inspection greatly.
The utility model is described in further detail below in conjunction with accompanying drawing.
The structural representation of general sampler when Fig. 1 is present detecting liquid product quality;
Fig. 2 is a front view of the present utility model;
Fig. 3 is the A-A cut-open view among Fig. 2.
The enforcement that accompanying drawing provides on the contrary is set with a hollow rubber ball 1 at the top of a cylindrical glass tube 2, have an aperture 3 on the glass tube 2 top tube walls, is marked with the scale 4 of demonstration liquid-column height with the glass tube 2 of lower part at aperture 3.During sampling glass tube 2 is inserted into liquid bottom, flatten rubber ball 1 and after to a certain degree, seal aperture 3, discharge rubber ball 3 then and make some bottom liquids that suck in the glass tube 2 more, sampler is proposed afterwards, by opening, seal aperture 3 or the unnecessary bottom liquid of compressing rubber ball 1 discharge, make liquid-column height in the glass tube 2 equal the actual grade of fluid product, the liquid that be deposited in the sampler this moment is institute's sample thief.
