Description
Technical field
The utility model relates to a kind of liquid taking device, particularly relates to a kind of liquid taking device that can be quantitative.
Background technology
In daily production and laboratory work, often need measure certain amount of fluid, such as liquid chemical reagent, the aqueous system etc.; In order to make the liquid volume of measuring more accurate, usually need be by means of beaker, graduated cylinder; Quantitative pipet; Even utensil such as electronic scale, operation is trouble very, and the resultant error of at every turn measuring is bigger.Simultaneously because to measure in the process operation link at liquid more, right utensil is many, causes the pollution of liquid easily, to producing and experiment test work generation adverse influence.In addition, because some liquid have toxicity and comb., operation link is too much, is easy to generate potential safety hazard.Therefore, also lack at present a kind of can accurate, safe, efficient method of measuring liquid.
Summary of the invention
Based on above-mentioned analysis, the purpose of the utility model be exactly to produce and the laboratory to measuring the needs of liquid preparation, design quantitative liquid getting device a kind of simple to operate, accurate, safe, efficient.
For realizing the purpose of the utility model, the technical scheme of employing is: comprise that air pressure produces system, liquid filling system and liquid output system, its constructional feature is:
(1) air pressure generation system is communicated with air by the pipeline that depends on chamber outer wall, and generation air pressure perhaps is connected with air-pressure duct;
(2) the liquid filling system is made up of cavity, piston and spring member, and its cavity volume is adjustable, in the combined action lower chamber generation negative pressure of air pressure and spring, and perfusion fluid;
(3) the liquid output system is a pipeline that is provided with spring valve at interface.
Described a kind of manual quantitative liquid getting device, its characteristics are that the volume of cavity is by regulating through the liquid measure adjust bar of getting that is arranged at the pressure handle bottom.
Described a kind of manual quantitative liquid getting device, its characteristics are that spring is placed in depression bar and at pressure handle with get between the upper end of sap cavity body.
Described a kind of manual quantitative liquid getting device, its characteristics are that the material of piston is the silica type material, and the internal diameter of its external diameter and cavity is just tangent.
Wherein, the liquid capacity control apparatus is positioned at the lower end of pushing handle, and its adjustable in length presses down the output that length is regulated liquid through adjusting; Anchor fitting is for being the cylinder of " recessed " shape, and the outer wall of cylinder has screw thread, is connected with the liquid storage container mouth; In the middle of the cylinder is the open circles shape, has screw thread on the wall, with the outer wall thread embedding mutually of cylindrical cavity.
Pressure system depends on the cylindrical cavity outside wall surface, is made up of a hollow metal or plastic conduit.Wherein the port of pipe outside is helicitic texture, is connected with induction tract with convenient.
Liquid produce system by a cylinder type hollow cavity, piston, push handle, depression bar and spring and form.Piston is positioned at the cylinder type hollow cavity, and the internal diameter of its external diameter and cavity is just tangent, and material is made up of silaatic, makes it can be up and down, has the leak free effect again.The depression bar upper/lower terminal combines with handle and piston respectively, and spring is placed in the depression bar outside, and two ends combine with the upper surface of handle and cavity respectively up and down.
The liquid output system then by a set inside pipeline of spring valve form, have two devices that play fixed stop plate and action of the spring respectively in the pipeline, there is a device that plays the effect of one-way check baffle plate sheet the lower end; Spring is connected between two devices in upper end simultaneously; Make liquid under the effect of manual press handle, liquid can be flowed out in pipeline, and when cavity begins perfusion fluid; The baffle plate sheet can seal delivery piping again, makes cavity can be in the state of a negative pressure.
Description of drawings
Fig. 1 is the scheme drawing of manual quantitative liquid getting device.
Fig. 2 is the scheme drawing of liquid output pipe road valve.
Among the figure, the 1st, get liquid and push handle, the 2nd, get the liquid measure adjust bar, the 3rd, hollow cavity upper end, the 4th, depression bar; The 5th, piston, the 6th, get liquid interface, the 7th, the liquid output pipe road, the 8th, get liquid interface, the 9th, the hollow cavity body cavity; The 10th, fixing spiral cover, the 11st, air-pressure duct, the 12nd, spring, the 13rd, spring fitting device; The 14th, little spring, 15 baffle plates, 16 baffle fixings, the 17th, baffle plate stopper.
The specific embodiment
For the utility model is done further to understand, combine accompanying drawing bright specifically to its work at present.
After treating that above-mentioned steps is accomplished, fabricate block is inserted in the hollow cylinder cavity 9.Be provided with the interface 6,8 of several different liquids outpuies in the lower end of cavity, under the coupling of adjust bar 2, can select different outpuies.Liquid output unit 7 is connected in the output interface 6 or 8 of cavity; Through effects such as baffle plate sheet anchor fitting 16, baffle plate one-way check device 17 and spring fitting devices 13; And under the effect of spring 14; Make baffle plate sheet 15 can controlling liquid can nonreturn flow, sealing effectiveness is arranged again when cavity begins perfusion fluid simultaneously.At last, the anchor fitting 10 with liquid taking device combines with circular cylindrical cavity through screw thread.So far, promptly formed manual quantitative liquid getting device.
In use, at first, the lower end of cavity 9 is immersed in the liquid fully with anchor fitting 10 and liquid storage container interface rotational fixation.Secondly select breather line 11 to be and air communication according to the input of liquid, still be connected with more atmospheric induction tract can be provided.Once more, according to getting liquid measure, regulate the length of getting liquid measure adjust bar 2; And delivery piping 7 is connected in interface 6 or 8, through pushing handle 1 air in the cavity is drained, under the effect of spring 12; In the cavity of certain volume, will form negative pressure state; Liquid baffle plate sheet 15 was and closed sealing state this moment, regulated suitable air pressure simultaneously, and liquid is filled cavity gradually.Push handle 1 once more, the i.e. quantitative outflow from pipeline 7 of liquid.
