Abstract
The utility model relates to an automatic fluid infusion device used for quantity liquid taking of reagent or water in chemical analysis or chemical industry. The bottleneck of a liquid storing bottle is matched with a sealing cover or plunger; the upper end of a capillary tube extends out the bottleneck and the lower end extends into the liquid storing bottle. The lower portion of the liquid storing bottle is provided with a liquid outlet capillary tube whose liquid outlet opening extends a certain distance under the liquid storing bottle. In liquid taking, the liquid outlet capillary tube extends to the bottom of a liquid taking cup and the liquid in the liquid storing bottle slowly flows out from the liquid outlet capillary tube to enter into the cup. Meanwhile an air inlet capillary tube constantly supplements air to the inner portion of the liquid storing bottle. When the liquid level in the cup reaches a predetermined height, the liquid outlet tube automatically stops liquid outlet to obtain the purpose of automatic fluid supplement.
Description
Technical field
The utility model relates to a kind of automatic liquid supply device, be used for need be repeatedly the quantitative occasion of fluid infusion, as be used for the quantitative fluid infusion of chemical analysis or chemical industry to water or reagent solution.
Background technology
In the automatic sampler of high-grade analytical instrument, all to clean before each sample introduction with distilled water, the supply of distilled water is to be finished by micro pump usually, this has increased the trouble spot of instrument.In addition, often need to measure quantitatively repeatedly in Chemical Manufacture with a kind of reagent solution (or water), manual operations is cumbersome and quantitatively inaccurate easily.
Summary of the invention
The purpose of this utility model provides a kind of automatic liquid supply device, and it is feeding-in liquid in same container automatically and accurately, can stop fluid infusion automatically after reaching the predetermined fluid level height, to simplify the operation and to save equipment cost and operating cost greatly.
This automatic liquid supply device has a reservoir, and bottleneck is furnished with seal, for example can be gland bonnet or sealing-plug, and the air inlet kapillary is pegged graft with gland bonnet and linked to each other, and stretch out outside the bottleneck upper end capillaceous, and the lower end is stretched in the reservoir, and the bottom of reservoir is provided with drain pipe.
Air inlet kapillary and gland bonnet can be conjoined structures, and the insertion depth of air inlet kapillary in reservoir immobilizes.The automatic liquid supply device of this structure is exclusively used in the fluid infusion to certain a certain amount of liquid.
Air inlet kapillary and gland bonnet can be the branch body structures, and bottleneck generally adopts rubber seal plug, and the air inlet kapillary runs through vertical jack of rubber plug and links to each other with the jack clamping.The automatic liquid supply device of this structure can be regulated air inlet insertion depth capillaceous, changes the height of the lower end mouth of pipe, to obtain different pressure reduction, realizes different amount infuseds.
Contain liquid in this fluid infusion device reservoir, the bottleneck sealing, insert in the interior liquid of bottle air inlet kapillary lower end.When getting liquid, make drain pipe stretch into the liquid taking cup bottom, liquid promptly flows out gradually from drain pipe and enters in the cup in the reservoir, the kapillary of air inlet simultaneously constantly mends air in reservoir, when liquid level reaches predetermined altitude in the cup (when the static pressure of liquid equates in the pressure of fluid and the cup), drain pipe promptly stops fluid automatically.When water in the cup is all or part of pour out after, this device can be automatically mended water in the cup to the same water level.So reach the automatic purpose of quantitative water compensating repeatedly.
Description of drawings
Accompanying drawing is represented the structure and the fluid infusion state thereof of this automatic liquid supply device.
As shown in the figure, contain liquid in the reservoir 3, bottleneck is with rubber plug 2 sealings, air inlet kapillary 1 runs through with rubber plug by vertical hole of rubber plug 2 and links to each other, and rubber plug 2 is stretched out in the upper end of kapillary 1, and the lower end is stretched in the reservoir 3, and can vertically move up and down in the hole, regulate the insertion depth in the bottle; The bottom of reservoir is provided with kapillary 4, and its lower end liquid outlet extends to the below of reservoir 3.Liquid taking cup 5 is connected to as shown the below of drain pipe 4, and make endpiece capillaceous stretch into the bottom of cup 5, liquid promptly flows to cup 5 gradually from drain pipe 4 in the reservoir, the kapillary of air inlet simultaneously 1 constantly mends air in reservoir 2, when liquid level rises to certain altitude in cup 5, the 4 endpiece pressure equilibriums of fluid kapillary, the fluid kapillary promptly stops fluid automatically.After water in the cup all removed or removing a part, again can be automatically with fluid infusion in the cup to predetermined liquid level.The height of predetermined fluid level can be regulated by changing air inlet insertion depth capillaceous in the cup.Air inlet kapillary 1 downward insertion depth is dark more, and then liquid outflow amount is more little, and the predetermined fluid level of fluid infusion is just low more, otherwise then the fluid infusion predetermined fluid level is high more.Air inlet insertion depth capillaceous is in case after fixing, then each automatic liquid supply all can be mended to same liquid level, reaches the purpose of automatic ration fluid infusion.
Claims (3)
1. the automatic liquid supply device is characterized in that having a reservoir, and bottleneck is furnished with seal, and the air inlet kapillary is pegged graft with the seal of bottleneck and linked to each other, and stretch out outside the bottleneck upper end capillaceous, and the lower end is stretched in the reservoir, and the bottom of reservoir is provided with drain pipe.
2. automatic liquid supply device according to claim 1 is characterized in that air inlet kapillary and bottleneck seal are conjoined structures, and the insertion depth of air inlet kapillary in reservoir fixed.
