It it not the automatic liquid metering device that can regulate of a kind of amount liquid measure.
Background technology
In the fields such as chemistry, chemical industry, medical treatment, water analysis, the most pending or to be analyzed
The measuring of liquid can use the letters such as traditional measuring cup, graduated cylinder, pipet, burette, volumetric flask
Easy metering device carries out manual operation and is realized, but such device needs operator to grasp necessarily
Technical ability, the accuracy of metering also varies with each individual, and cannot realize automatic gauge.Peristaltic pump is
One class can be applicable to the fexible unit of the on-line automatic metering of fluid, although complete machine stability can be relatively
Good, but bulky, price is the most expensive, precision is the highest, and bare machine (OEM series) although
Volume is little, low price, but its precision is easily belonged to by metering fluid behaviour, metering frequency, flexible pipe
The impact of the many factors such as property, ambient temperature, number of rollers, card thrust, precision is on the low side,
Can not meet the requirement of precise volume liquid.
Summary of the invention
For the drawbacks described above overcoming existing metering device to exist, this utility model is provided a kind of
Measure liquid convenience, precision practicality high, structurally simple, economical, and amount liquid measure is freely adjustable
Quantitative automatic liquid metering device.
The technical solution adopted in the utility model is:
Automatic liquid metering device, including cylindrical tube and the controller of hollow, its feature exists
In: the top of described cylindrical tube and bottom seal respectively be provided with screw thread top cover and
Bottom, surface configuration has scale mark, and the upper and lower part of side is provided with feed tube respectively and goes out
Liquid pipe；The inner chamber of described cylindrical tube is provided with overflow pipe, and described overflow pipe is axially worn
Cross bottom, and described overflow pipe is connected with described bottom by bolt；Described overflow
The upper end of pipe extends to the inner chamber of cylindrical tube, and cylindrical tube is stretched out in lower end；
The external rubber tube of described feed tube is provided with feed tube electrical clip pipe valve；
The external rubber tube of described drain pipe is provided with 3-position-3-way solenoid valve；
Being provided with evacuated tube on described bottom, the external rubber tube of described evacuated tube is provided with
Evacuated tube electrical clip pipe valve；
Described controller respectively by control signal wire and feed tube electrical clip pipe valve, three three
Three-way electromagnetic valve and evacuated tube electrical clip pipe valve connect.
The upper-lower position of described overflow pipe is adjustable.
The upper end of described overflow pipe is set to concordant overfall, and the height of upper end is higher than
The top edge of liquid pipe.
It is provided with rubber washer between described bolt and bottom.
Controller of the present utility model can realize timing unattended operation, improves metering device
Safety and reliability；The overfall height of overflow pipe can freely regulate, according to quantifier cylinder
The scale mark of surface just can regulate the amount of liquid needing to measure, and measures value accurate, not only
The occasion of the amount of being applicable to liquid measure change, and have also been enlarged the range ratio that metering device measures；Go out
Liquid pipe is arranged on quantifier side, and arranges one three three on the external rubber tube of drain pipe
Three-way electromagnetic valve, can effectively prevent gas in drain pipe from being closed by liquid and being difficult to the problem discharged,
Thus improve the accuracy of device metering；Liquid to be measured enters quantifier from feed tube, many
The liquid gone out overflows from interior overflow pipe and reclaims, and the liquid measured is flowed out by drain pipe, whole
The process that measures is carried out under air-tight state, and safety is high, clean hygiene.
The beneficial effects of the utility model are embodied in:
1, can timing, automatically quantitative liquid is measured, quantification stability, accuracy height,
Use the adjustable interior overflow pipe of overflow height simultaneously, extend the amount liquid scope of metering device.
2, the feature that operation is convenient, easy to use, can be widely applied to chemistry, chemical industry, doctor
The automatic measurement of quantitative liquid in the fields such as treatment, water analysis.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram.
