Abstract
The utility model relates to an automatic constant volume liquid feeder, which is used for preparing liquid for medical, chemical industry, food, pharmacy, etc. in the quantitative and timing form. The utility model is characterized in that the utility model is composed of a U-shaped tube and a two-bit three-way valve arranged at the bottom of the U-shaped tube. The an open-close air compressor lifting liquid in low-position container and syphon the liquid in the high-position container by compression for positioning and accomplishes the quantitative and timed metering with the utility model. The liquid quantitative meter has the advantages of strong acid resistance and high alkali measuring accuracy and matches with a micro computer for programme control. The utility model can automatically complete the timing and quantitative work and is suitable for the industries such as the chemical industry, the pharmacy industry, the food industry, etc. for allocating liquid in the quantitative and timing form.
Description
The utility model relates to a kind of liquid automatic ration supply device that is used for industries such as medical treatment, chemical industry, food, pharmacy, breed, water treatment technology, water quality monitoring, soilless culture, the automatic configuration of highclass perfumes.
Along with developing rapidly of science and technology, industrial departments such as biology, chemical industry need special fluid regularly, the technology that quantitatively adds is increasing, but the liquid quantitative of Chu Shouing only is to adopt syringe of artificial drawing in the market, suck and extrude liquid and carry out quantitatively, not only measuring accuracy is low, and can't carry out full automatic working, and very the current development in science and technology of incompatibility needs.
The purpose of this utility model is the liquid automatic ration supply device of design a kind of anti-strong acid, highly basic, and it can be under micro computer programmed cooperation, regularly, quantitative provide required liquid.
Liquid automatic ration supply device described in the utility model is to form like this.It by a U type pipe and automatically controlled, the two-position three-way valve that is installed in U type pipe bottom, be connected U type pipe and liquid bottles suction pipe, be installed in the fine setting turn-knob on the suction pipe and the air pump that links to each other with liquid bottles, the reversible electric machine that links to each other with the two-bit triplet valve core forms.After air pump starts, give plus-pressure in the liquid bottles, force bottle interior liquid to rise in the U type pipe through suction pipe.After air pump quits work, because the space in the air pump is siphoned in the liquid bottles the interior excess liquid of U type pipe.When the two-bit triplet valve core of U type pipe bottom rotated to the top, U type pipe became a communicating pipe, and after the two-bit triplet valve core rotated 90 degree, the outlet of right half U type pipe and two position three-way valve was connected, and just flowed out at right half U type liquid in pipe.After the two-bit triplet valve core upwards rotated 90 degree once more, the liquid in the left half U type pipe flow in the right half U type pipe by the spool of two-position three-way valve, had got rid of air in the spool, had guaranteed measuring accuracy next time.The height of fine setting turn-knob adjustable pipette in right half U type pipe, thus reach the purpose that changes quantitative values.Air pump, fine setting turn-knob and reversible electric machine are controlled by microcomputer program.
Liquid automatic ration supply device described in the utility model has anti-strong acid, advantage that the highly basic measuring accuracy is high.Cooperate microcomputer program control can reach timing, quantitative.Be fit to be applied in the quantitative Recipe of industries such as chemical analysis, pharmacy, food, chemical industry.Liquid quantitative such as strong acid, highly basic, this instrument of timing are indispensable parts in environment supervision instrument.
Embodiment
Accompanying drawing: liquid automatic ration supply device structural representation.
Wherein 1. air pumps, 2. liquid bottles, 3. suction pipe, 4. right half U type pipe, 5. left half U type pipe, 6. two-position three-way valve, 7. the fine setting turn-knob, 8. the pipe 9 reversible electric machines
With reference to the accompanying drawings high-precision liquid quantitative instrument structure described in the utility model is carried out detailed narration below.
Get a glass tube or polyfluortetraethylene pipe or other composite, be made into a U type pipe, adorn a two-position three-way valve (6) in the bottom of U type pipe, spool links to each other with a reversible electric machine (9), two-position three-way valve is divided into right half U type pipe (4) and (5) two parts of left half U type pipe with U type pipe, a suction pipe of termination (3) on right half U type pipe, the other end of suction pipe extend in the interior liquid of liquid bottles (2), on suction pipe, adorn a fine setting turn-knob (7), air pump (1) places outside the liquid bottles, stretched in the liquid bottles by pipe (8) one ends, the other end is connected with air pump.Air pump, fine setting turn-knob and reversible electric machine are controlled by microcomputer program.
Claims (1)
