Abstract
The utility model relates to a fluid quantitative distributor, which comprises an upper static valve (1), a lower static valve (2), a quantitative distribution movable valve (3) that is arranged between the upper and the lower static valves, and at least two sampling units. The quantitative distribution movable valve (3) tightly moves between the upper static valve (1) and the lower static valve (2). The sampling unit consists of the upper static valve (1), and a fluid sample intake passage (4) and a fluid discharging passage (5), which have the identical cross section inside and are arranged inside the upper static valve (1), and a storage pipe (6) that is arranged inside the quantitative distribution movable valve (5) an with the cross section being identical to that of the fluid sample intake passage (4). The storage pipe (6) in the sampling unit cannot be simultaneously communicated with the fluid sample intake passage (4) and the fluid discharging passage (5). The distance between two storage pipes (6) in the two adjacent sampling units is identical, and the distance between the fluid sample intake passages (4) is equal, and the distance between the fluid discharging passages (5) is equal. The fluid quantitative distributor has correct quantitative distribution of the fluid and rapid speed, and can be widely applied to the quantitative analysis field.
Description
Technical field:
The utility model relates to a kind of quantitative distributing device, a kind of specifically fluid quantitative divider.
Background technology:
At present, in biochemical analysis, often need get a certain amount of fluid and analyze, conventional sampling mode is to pipette a certain amount of fluid with transfer pipet or liquid-transfering gun.But get the fluid of specified quantitative at needs, and the number of times of sampling is more for a long time, lower by the mode sampling efficiency of transfer pipet or liquid-transfering gun, do not catch up with the needs of analysis.
The utility model content:
The purpose of this utility model is to provide a kind of fluid quantitative divider that can finish a plurality of a certain amount of fluid sampling work fast.
The utility model is achieved in that
A kind of fluid quantitative divider comprises quiet valve 1 and following quiet valve 2, goes up rationed moving valve 3 and at least two sampling units between quiet valve 1 and the following quiet valve 2; Rationed moving valve 3 is in last quiet valve 1 and closely motion between the quiet valve 2 down; Sampling unit is to constitute with the big or small identical storage tubes 6 of fluid sample intake passage 4 xsects by in the fluid sample intake passage 4 that identical cross-section is arranged in last quiet valve 1 and the following quiet valve 2 and fluid sample output passage 5 and the rationed moving valve 3; Storage tube 6 in the sampling unit can not be simultaneously and fluid sample intake passage 4 and 5 connections of fluid sample output passage; Distance in adjacent two sampling units between the storage tube 6 equates that the distance in adjacent two sampling units between the fluid sample intake passage 4 equates that the distance in adjacent two sampling units between the fluid sample output passage 5 equates.
Further scheme is: rationed moving valve 3 is in last quiet valve 1 and rotation between the quiet valve 2 down.
Further scheme is: when rationed moving valve 3 rotated to certain angle, storage tube 6 and fluid sample intake passage 4 were communicated with and 5 connections of discord fluid sample output passage; When rationed moving valve 3 rotates to other angle, storage tube 6 discord fluid sample intake passages 4 be communicated with and and fluid sample output passage 5 be communicated with.
Further scheme is: following quiet valve 2 has fluid sample introduction overall channel 7, can be communicated with the storage tube 6 of all sampling units.
Further scheme is: described sampling unit constitutes the xsect size of fluid sample intake passage 4 and fluid sample output passage 5 and storage tube 6 and can adjust synchronously.
The utility model is at last quiet valve 1, when down storage tube 6 communicates in the fluid sample intake passage 4 of quiet valve 2 and the rationed moving valve 3, fluid enters storage tube 6, after fluid has been expired in storage in the storage tube 6, rationed moving valve rotates a certain angle, storage tube 6 has been aimed at fluid sample output passage 5, under the effect of pressure, fluid is exported by fluid sample output passage 6 from storage tube 6, thereby has finished the rationed of fluid.The utility model convection cell rationed accurately and also speed fast, can be widely used in the quantitative test field.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 moves the back view for the rationed moving valve 3 of the utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of fluid quantitative divider, by last quiet valve 1, following quiet valve 2, and be in quiet valve 1, rationed moving valve between the quiet valve 23 is formed down, the fluid quantitative divider is made of at least two sampling units, sampling unit by in last quiet valve 1 and the down quiet valve 2 by forming with the storage tubes 6 of fluid sample intake passage 4 xsects size same fluid in the fluid sample intake passage 4 of identical cross-section and fluid sample output passage 5 and the rationed moving valve 3, fluid sample intake passage 4 and fluid sample output passage 5 all could be communicated with by storage tube 6, the distance in adjacent two sampling units between the storage tube 6, distance between fluid sample intake passage 4 and the fluid sample output passage 5 equates.Fluid sample intake passage 4 bottoms link to each other with fluid sample introduction overall channel 7.
As shown in Figure 2, when using the utility model to carry out fluid rationed, storage tube 6 at first is in the position that is connected with fluid sample intake passage 4, fluid in the fluid sample introduction overall channel 7 enters fluid sample intake passage 4 and the storage tube 6 from the bottom, behind storage flowing full body in the storage tube 6, the rationed moving valve 3 of fluid quantitative divider moves certain distance, storage tube 6 is connected with fluid sample output passage 5, at this moment, under the effect of pressure, fluid in the storage tube 6 flows out by fluid sample output passage 5, can realize rationed purpose.And because the utility model can have a plurality of sampling units, primary sample can realize that a plurality of quantitative fluids distribute purpose.
In actual use, the amount of fluid sampling can be adjusted by the size of storage tube 6, therefore, sampling unit constitutes the xsect size of fluid sample intake passage 4 and fluid sample output passage 5 and storage tube 6 can be adjusted synchronously, thereby has guaranteed that the fluid quantitative divider can get the different fluid sampling amount.
