Abstract
The utility model relates to a safe and controllable liquid transferring device for taking the quantitative liquid, which comprises a compressible elastic body, an elastic connecting joint that is connected with a sucker and an elastic Y-type pipe that is connected with the joint. A suction valve and a dump valve are respectively arranged in the joint and the Y-type pipe. When absorbing the liquid, an air cavity and the suction valve respectively extruded to take the quantitative liquid. If the absorbed quantity is excess, the dump valve is extruded so that the excess liquid is discharged into the original vessel and then the dump valve is extruded to release the liquid into the target vessel so as to keep the liquid be taken rapidly and accurately. The utility model has simple structure and facility for manufacturing and can be applied for taking the chemical liquid medicine or the medical reagents.
Description
One, technical field:
The utility model relates to a kind of liquid suction amount instrument, particularly relates to the controlled liquid-transfering device of a kind of safety.
Two, background technology:
As everyone knows, in the chemical laboratory, the user of service often uses a kind of instrument of ear washing bulb to pipette various liquid, there is a spherical elastomer ear washing bulb upper end, the lower end is an elastic tube that is communicated with elastic ball, connect a glass tube that has scale in elastic connecting pipe bottom during use, ear washing bulb uses more convenient, but also exist certain shortcoming, suck the bad control of amount of liquid exactly, often must the repeated multiple times use just can be drawn onto suitable amount, waste many times, increase many troubles, especially time and consumption are being required under the very strict situation to work, can measure required liquid timely and accurately, different results and influence will be arranged.And common suction pipe is when imbibition, need catch to touch suction pipe pipe top interface with the control uptake, and hand is easily contaminated, and is dangerous.
Three, the content of utility model:
The purpose of this utility model: exist ground not enough for overcoming prior art, realize the controlled liquid-transfering device of safety.
Technical solutions of the utility model: the controlled liquid-transfering device of a kind of safety, comprise the sealing compressible elastomeric, and the elasticity jointing that links to each other with suction pipe, in the jointing of sealing compressible elastomeric the suction control valve is installed, below connecting first side suction control valve, the breeches pipe that links to each other with the elastomer inner chamber is installed, release control valve is installed in the breeches pipe.
The controlled liquid-transfering device of described safety, control valve are ball, or are general valve.
The controlled liquid-transfering device of described safety, compressible elastomeric are that rubber is made, or make for rubber-plastics material, or make for soft moulding.
The controlled liquid-transfering device of described safety, elastomer are spherical or are approximate elliposoidal elastomer.
The utility model beneficial effect:
1, the utility model is provided with by-pass valve control in the suction pipe jointing, and this valve is when being used for liquid assimilating, and by the convergent force confining gas of rubber, thereby compression once can be used for repeatedly imbibition, and need not catch and touch pipette top interface, and is very safe.
2, the utility model with elasticity breeches pipe that the elasticity jointing links to each other in be provided with control valve, when discharging liquid, discharge unnecessary liquid during more than aequum to former container in intake as required, when equaling aequum, intake discharges required liquid to the purpose container, thereby be easy to accurately draw certain quantity of fluid, time saving and energy saving.

Fig. 2: the spherical compressible elastomeric cross-sectional view of the band vertical ellipse of glass marble valve;
Fig. 3: the spherical compressible elastomeric cross-sectional view of the band horizontal ellipse of glass marble valve;

Fig. 5: the spherical compressible elastomeric surface structure of the vertical ellipse schematic diagram of general valve;
Fig. 6: the spherical compressible elastomeric surface structure of the horizontal ellipse schematic diagram of general valve.
Five, the specific embodiment:
Embodiment one: referring to Fig. 1, the pipette interface (4) of suction apparatus is socketed in pipette top interface, left hand is pinched and is drawn valve (2), open the gas passage, the right hand is pinched elasticity air cavity (1) and is discharged air, pipette is inserted in the liquid that needs to extract, slowly valve (2) is drawn in extruding, make between glass marble and the rubber and produce the slit, thereby allow elasticity air cavity (1) be connected with pipette, because the air pressure in the elasticity air cavity (1) is lower than atmospheric pressure, so solution is entered pipette by the powered that draught head provides.By the strength size adjustment rate of liquid aspiration of extruding absorption valve (2), control liquid absorption at last.From solution, take out pipette, if liquid absorption is more than aequum, can make pipette pass through breeches pipe relief valve (3) by extruding breeches pipe relief valve (3) communicates with external atmosphere pressure, because the gravity effect, required unnecessary liquid flows out to from pipette in the primary liquid container, pipette is placed the purpose container again, extruding breeches pipe relief valve (3), make pipette pass through breeches pipe relief valve (3) and communicate with external atmosphere pressure, under the gravity effect, required fluid to be measured flows out to from pipette in the purpose container.Also can not push breeches pipe relief valve (3), directly push air cavity (1), extruding absorption valve (2) blows out solution then.
Embodiment two: referring to Fig. 4, number identically with embodiment one, represent meaning identical, do not repeat, different is: glass marble valve 2 or 3 usefulness common valves replace.
Embodiment three, four: respectively referring to Fig. 2, Fig. 5, numbering is identical with enforcement embodiment one, two, represents meaning identical, does not repeat, and different is: the vertical oval ball of spherical elasticity air cavity 1 usefulness replaces.
Embodiment five, six: respectively referring to Fig. 3, Fig. 6, number identically with embodiment one, two, represent meaning identical, do not repeat, different is: the horizontal oval ball of spherical elasticity air cavity 1 usefulness replaces.
Claims (4)
