The utility model comprises an inner container 2, an outer container 1, and a displacement governor of a container connected; the inner container 2 is tightly connected with an outer container 1. The inner container is communicated with the outer container, and the inner container is connected with an automatic piston. The outer container is connected with a liquid inlet pipe 13 and a liquid outlet pipe 15, and the crossing point of the liquid inlet pipe and the liquid outlet pipe is provided with a cross valve 14. The utility model boasts of advantages of simple structure, convenient use, accurate filling quantitation, energy saving, wide application, etc.

Description

The liquid quantitative filling device

The utility model is a kind of liquid quantitative filling device that is used for industries such as medicine, chemical industry and light industry.

At present, electrodynamic type and mechanical type filling liquid device are arranged, they are applicable to industrialized production, and for the operation of short run liquid subpackage, and as in hospital preparation chamber, laboratory and the chemical industry shop during packing liquid, the certain structures that just seems is complicated and price is higher.

The purpose of this utility model provide a kind of simple in structure, cost is low and be specially adapted to the liquid quantitative filling device of short run liquid subpackage operation.

The purpose of this utility model is achieved in that and is provided with tight slip inside and outside container that interlocks and the container displacement governor that is attached thereto, inside and outside container communicates, and connect automatic piston on the former, repeatedly kick under the latter, drain pipe, cross valve is positioned at two liquid pipe cross intersections.

The effect of said vesse displacement governor is to regulate the internal volume that two containers are constituted, and control quantitatively.This regulator can comprise two fixed mounts and an adjusting screw(rod) that is attached thereto, and two fixed mounts are separately fixed at the top of inside and outside container.

Above-mentioned automatic piston is an one-way cock, and the effect of it and cross valve is the flow direction of controlling liquid, realizes the quantitative filling process.

The utility model has the advantages that: the one, simple in structure, easy to use.The 2nd, can be applicable to liquid subpackage of different nature, can is quantitatively accurate, controllable dose.The 3rd, adopt fluid pressure to be used as power, do not consume energy.The 4th, be widely used, be specially adapted to the packing of liquid such as hospital preparation chamber, laboratory, chemical industry, shop.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing

Accompanying drawing is a structural representation of the present utility model.

As shown in the figure: be provided with inner pressurd vessel 2, outer container 1, both communicate and interlock like the such tight slip of syringe, the container displacement governor control of its slide displacement amount by being attached thereto.Connect automatic piston on the inner pressurd vessel.Repeatedly kick under the outer container,

drain pipe

13,15, two liquid pipe cross intersections are equipped with cross valve 14.

The container displacement governor comprises that two fixed mounts 3 and 4, two fixed mounts of an adjusting screw(rod) that is attached thereto are contained in the top of inside and outside container 2,1 respectively.Each fixed mount all has two clamping bars, by bolt 11 they is fixed on the top of container.Clamping bar is straight-bar or arc curved bar.Like this, turn screw rod, inner pressurd vessel 2 is slided up and down in outer container 1, to regulate the internal volume that they are constituted: after going up slip, outer container retains the space and increases, and then the internal volume of two containers formation increases; Otherwise after the lower slider, outer container retains the space to be reduced, and then the formed internal volume of two containers reduces, and quantitatively records purpose thereby reach.The through hole 12 of turnover is for liquid arranged at inner pressurd vessel 2 bottoms.

Automatic piston is similar to umbrella (or other shape) outward, on (umbrella top) the air air admission hole is arranged, and has arm to be communicated with inner pressurd vessel 2 down, and the middle part is umbrella shape cavity 7 and round table-like piston 8 is arranged that salient point 6 or other form structure are arranged at the bottom of the chamber.The effect of salient point is, allows piston 8 back that sinks leave the gap with cavity 7 bottoms, so that allow air enter in the container, helps liquid to flow out from drain pipe 15.Arm can be one whole form, also can be made up of the arm 5,10 that is connected as a single entity with automatic piston, inner pressurd vessel respectively, and this two pipe equal diameter and butt joint back link to each other with rubber case 9 or alternate manner (as bonding).

Automatic piston and inside and outside container are glassware, the product that can select for use Danyang, Jiangsu Jiang Ye glass apparatus factory to produce.This container is that ground connects.Except that the container displacement governor was metal material, surplus was glass or stainless steel.

The utility model principle of work is: the liquid in fluid box (it is put and highly surpasses the automatic piston height) is because hydrostatic pressure (potential energy), flow into and through the cross valve 14 of feed tube 13, drain pipe 15 intersections by the A direction, outside flowing in the direction of arrows, in the inner pressurd vessel 2,1, rise to automatic piston after being full of, piston 8 is risen under buoyancy, block air admission hole, promptly piston is closed.Open cross valve this moment, and the liquid flow channel is that feed tube is closed, and flow pass is that drain pipe is opened, and then liquid is because action of gravity and air pressure (piston 8 sinks, and air admission hole is opened, and air enters) and flowed out through the B direction by drain pipe 15 rapidly.Finished the expendable process.Repeat above action, just can constantly finish the liquid subpackage task.

The liquid quantitative process is: open cross valve, after liquid entered container and is full of, piston was closed; Open cross valve again, liquid flows out to measuring cup, sees the scale that whether reaches regulation.Error is arranged, turn adjusting screw(rod) 4 and make inner pressurd vessel or go up or lower slider the amount of change container carrying liquid.Repeat above-mentioned action once more, till reaching scale.Later just liquid subpackage work can have been carried out.
