Abstract
The utility model discloses a liquid quantifier, comprising a semi-cylinder lifting handle with a cover, a baffle ring, a metering cylinder, a fastening turn knob, a turn knob quantitation disc, a metering cylinder inner plunger, a metering screw-shaped post, a liquid outlet ball-valve, a liquid feeding ball-valve, an air intake valve, a quantifier body, a liquid suction tube, a metering cylinder liquid inlet, a metering cylinder liquid outlet, a liquid drain tube, a liquid drain tube cover and a bottle opening interface. The utility model has convenient and accurate operation and no environmental pollution, the measuring accuracy can reach 0.2-3% according to the different ranks and volumes, which can reach the state specified standards. The precision of repeated use can reach 0.1-0.3%.
Description
The utility model relates to a kind of liquid quantitative device, belongs to by the volumetric metering technical field.
At present, laboratory worker is quantitatively being used acid, and alkali has, during non-toxic aq, and normal with the liquid in the quantitative measuring cup of vision, the graduated cylinder or use the suction pipe dose, the amount of getting is difficult for accurately, get down repeatedly operate inconvenient, and because of the gaseous contamination environment of volatile liquid.
The purpose of this utility model be overcome above-mentioned prior art exist can not be once the accurate shortcoming of dose liquid, gaseous contamination environment and design a kind of liquid quantitative device.
Basic mechanism of the present utility model is to utilize hydraulic pressure and inhale the effect of pressing, and adopts the opposite ball valve of both direction to come dose liquid, reaches liquid storage bottle internal gas pressure balance with gas admittance valve.
The technical scheme that the utility model is implemented is that this batcher is made up of plug, metering screw thread mark post, fluid ball valve, feed liquor ball valve, gas admittance valve, batcher main body, liquid tail pipe, metering cylinder inlet, metering cylinder liquid outlet, discharging tube, discharging tube block and bottleneck interface in semi-barrel shape lifting handle with cover, baffle ring, metering cylinder, tightening knob, knob quantitative disk, the metering cylinder.Form lift portion by plug, metering screw thread mark post in semi-cylindrical shaped lifting handle with cover, the metering cylinder, the knob quantitative disk freedom on graduated metering screw thread mark post that has or do not have a scale is rotated mobile up and down, after it is quantitatively located, be fixed with tightening knob, there is the sealing that is connected with the batcher main body of being made up of liquid inlet and outlet ball valve, gas admittance valve, liquid tail pipe, bottleneck interface and discharging tube etc. of the metering cylinder of a baffle ring, lower end the upper end in addition.Bottleneck interface and liquid storage bottle bottleneck join, and the discharging tube block is used for the back shutoff discharging tube mouth of pipe.
Because above-mentioned embodiment has adopted batcher to get liquid, easy to operate, accurate, because batcher and liquid storage bottle are whole sealing status and free from environmental pollution, product has reached state specified standards by different brackets and the also different 0.2-3% that reaches of volumetric metering precision again.Reuse precision and reach 0.1-0.3%.
Be described further below in conjunction with accompanying drawing.
Accompanying drawing 1 is a liquid quantitative device structural profile synoptic diagram, among the figure: 1-semi-barrel shape lifting handle with cover; The 2-baffle ring; The 3-metering cylinder; The 4-tightening knob; 5-knob quantitative disk; Plug in the 6-metering cylinder; 7-metering screw thread mark post; 8-fluid ball valve; 9-feed liquor ball valve; The 10-gas admittance valve; 11-batcher main body; 12-liquid tail pipe; 13-metering cylinder inlet; 14-metering cylinder liquid outlet; The 15-discharging tube; 16-discharging tube block; The 17-liquid storage bottle; And 18-bottleneck interface.
Accompanying drawing 2 is a liquid quantitative device lift portion structural profile synoptic diagram, among the figure: 21-semi-barrel shape lifting handle with cover; Plug in the 26-metering cylinder; 27-metering screw thread mark post.
Such as Fig. 1, shown in Figure 2, at semi-barrel shape lifting handle 1(with cover or 21) be connected with in the hopper with lid in the tube and fill in 6(or 26), one side is connected with a metering screw thread mark post 7(or 27 with scale), plug in the hopper 6 is inserted by fluid ball valve 8, feed liquor ball valve 9, intake valve 10, liquid suction line 12, in the hopper 3 with baffle ring 2 that the upper end of the batcher main body 11 that forms with the discharging tube 15 of filter screen 19 and bottleneck interface 18 is communicated with and connects airtight with main cavity, then knob quantitative disk 5, tightening knob 4 is screwed on the metering screw thread mark post 7 successively, and bottleneck interface 18 and liquid storage bottle 17 are connected airtight. A kind of no scale knob quantitative disk is used for the primes batcher, and a kind of graduated being used on the select quality is the micromatic setting of extracted with high accuracy liquid. The bottleneck interface is screw socket and inside and outside plug mouth (not shown), is convenient to join with various bottlenecks. The liquid suction line is straight pipe type or is the elbow type of anti-impurity that the elbow top is shut, and there is the feed liquor hole at the top all around on the lower, can prevent that impurities in liquid from entering the liquid suction line.
Use first (use needn't) to need air scavenge in the device, its method be that several slightly carries, presses lifting handle 1 to get final product again. The quantitative liquid getting method is, after knob quantitative disk 5 is screwed into the aequum graduation mark it is tightened up with tightening knob 4, gently carry lifting handle 1, knob quantitative disk 5 tops on the metering screw thread mark post 7 are got final product near the bottom of baffle ring 2, owing to propose the suction that produces on the plug 6 in the hopper, the impact of liquid storage bottle 17 interior liquid is opened feed liquor ball valve 9, stopping a liquid counter-pressure wink presses off feed liquor ball valve 9, the light lifting handle 1 of pressing, fluid pressure presses off fluid ball valve 8, and required quantitative liquid is discharged along discharging tube 15. Because liquid storage bottle 17 interior generation negative pressure, atmospheric pressure backs down intake valve 10 when carrying lifting handle 1, and making behind bottle inside and outside air pressure balance can autoshutdown, with after discharging tube block 16 is covered tightly to guarantee the hermetically sealed of this device of time spent not.
Embodiment: plug in the metering cylinder of the lifting handle part of pressing said structure is inserted in the metering cylinder of batcher main body, good and sound knob quantitative disk also connects this device and liquid storage bottle, as need 3 milliliters of liquid, quantitative disk is threaded on the mark post fixes with tightening knob behind 3 milliliters of positions of target, promote lifting handle, after quantitative disk top and baffle ring bottom are close to, a moment the light lifting handle of pressing, liquid along discharging tube flow out get final product 3 milliliters liquid.
