Summary of the invention:
In order to solve the problems of the technologies described above, the invention provides a kind of big flow flow cell.
The technical solution adopted for the present invention to solve the technical problems is: a kind of big flow flow cell, being provided with first-class latus rectum is the liquid in-out valve of 4mm, described liquid in-out valve is embedded with two glands, on the same position on the mutual opposite of described two glands, offer two interior concave stations respectively, be provided with two quartz glass plates and two fixture blocks between described two glands, described fixture block is arranged between the interior projection of two glands, make a space that forms flow liquid between two glands after the amalgamation simultaneously, described fixture block bottom joins with the edge of quartz glass plate, and two quartz glass plates fixedly are embedded on the flow liquid viewport of two glands respectively by fixture block, the described liquid in-out valve left and right sides is provided with left end cap, right end cap, described left end cap, the liquid in-out valve, right end cap is fixed into one by trip bolt.
Fixing reliable in order to make between fixture block and the gland, further: described fixture block is fixed on the gland by straight pin.
Fixing reliable in order to make between left end cap, liquid in-out valve and the right end cap, further: the quantity of described trip bolt is at least 3.
Adjustable in order to realize light path, further: described quartz glass plate plate is the design of single face boss.
For the ease of installing, further: the integral body of described liquid in-out valve, left end cap, right end cap all adopts squared design, and described liquid in-out valve bottom is provided with two screw hole is installed.
The present invention is as follows with respect to its advantage of prior art:
1, the fluid latus rectum reaches 4mm, and it is little and cause the little situation of flow to have solved latus rectum;
But 2 Fast Installation and disassembly, cleaning, by three screw retention, backing out three screws can be with dismounting and change or the cleaning one by one of flow cell inner body;
3, light path is adjustable: change the positive and negative of two quartz glass plates, can adjust the size of light path.As shown below, optional light path is three kinds of 0.5mm, 1.5mm, 2.5mm.

Embodiment:
The present invention is further described below in conjunction with drawings and Examples.
A kind of big flow flow cell shown in Fig. 1～5 is provided with the liquid in-out valve 1 that first-class latus rectum is 4mm, described liquid in-out valve 1 is embedded with two glands 2, on the same position on the mutual opposite of described two glands 2, offer two interior concave station 2-3 respectively, be provided with two quartz glass plates 4 and two fixture blocks 5 between described two glands 2, described fixture block 5 is arranged between the interior projection 2-3 of two glands 2, make a space that forms flow liquid between two glands 2 after the amalgamation simultaneously, described fixture block 5 is fixed on the gland 2 by straight pin 7, the thickness of described fixture block 5 is 1/3～1/2 of this gap, the edge of described fixture block 5 bottoms and quartz glass plate 4 joins, and two quartz glass plates 4 fixedly are embedded on the flow liquid viewport 2-2 of two glands 2 respectively by fixture block 5, described liquid in-out valve 1 left and right sides is provided with left end cap 3-1, right end cap 3-2, described left end cap 3-1, liquid in-out valve 1, right end cap 3-2 is fixed into one by trip bolt 6, for the ease of fixing, the quantity of this trip bolt 6 is 3, for the ease of installing, described liquid in-out valve 1, left end cap 3-1, right end cap 3-2 integral body all adopts squared design, and described liquid in-out valve bottom 1 is provided with two screw hole 8 is installed.And in order to arrive the adjustable of light path, described quartz glass plate 4 can adopt the design of single face boss, so just can adjust the size of light path by changing the positive and negative of two blocks of quartz glasss.Two quartz glass plates just can done shown in following Fig. 6～8-just, just-and anti-, anti--anti-three kinds of combinations, the optional light path of its correspondence is three kinds of 0.5mm, 1.5mm, 2.5mm.
When the liquid import inlet of liquid to be detected by liquid in-out valve 1 enters, because the formed space of concave station 2-3 is big in after 2 amalgamations of 5 to two glands of fixture block, so, do not overlap fully between two glands, there is certain clearance, at this moment, liquid to be detected just can flow into two quartz glass plate 4 slits by this gap, is flowed out by liquid outlet then; In this simultaneously, detect light and send (deuterium lamp/halogen tungsten lamp etc.) by light source, inject in the flow cell perpendicular to quartz glass plate 4 logical light faces, pass that the quartz glass plate 4 logical light faces from the opposite penetrate behind the fluid, penetrate light and receive also analyzing and processing, thereby reach the effect of material in the test fluid by the CCD detecting device.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
