Abstract
The utility model discloses a fluid infusion structure, including liquid storage pot, flowmeter measurer and horizontal pipeline, the flowmeter measurer set up in the liquid storage pot rear end, horizontal pipe setup in flowmeter measurer rear end. Its characterized in that: the liquid storage pot is higher than horizontal pipeline, horizontal pipeline is higher than the flowmeter measurer. Since adopted this kind of structure, can the inside full of liquid always of dependable flow counter to the fluid infusion precision has been improved.
Description
Technical field
The utility model relates to chemicals fluid infusion field, is specifically related to a kind of fluid infusion structure.
Background technology
In numerous field relating to chemicals and use such as chemical industry, semiconductor, photovoltaic and biological medicine, how robotization, quantitatively to add chemicals be accurately a comparatively basic problem.Current automatic liquid supply device category is various, but is mainly divided into following a few class in principle: the first kind, mode of fixing time, and controls amount infused by the time controlling fluid infusion valve open, and the shortcoming of the method is when the unstable time error of flow velocity is larger; Equations of The Second Kind, determines volumetric manner, and the liquid level difference between upper and lower two liquid level sensors can determine a fixing volume, the solution filling into this fixed volume can be controlled by monitoring liquid level sensor signal, this method is relatively stable, and fluid infusion velocity is very fast, and shortcoming is that precision is not high; 3rd class, flow gauge mode, is then converted into bulking value by measuring the umber of pulse flowing through flow gauge, the method precision is higher, but flow gauge is comparatively accurate, if pipeline or meter inside exist bubble in fluid infusion process, then can have an impact to measuring accuracy.
As can be seen here, if the impact of bubble flow meter measuring device in fluid infusion process can be eliminated, the precision improving fluid infusion system will be conducive to.
Summary of the invention
The utility model object is to provide a kind of fluid infusion to construct, and this structure overcomes the deficiency of existing fluid infusion structure, advantageously in the precision improving fluid infusion system.
For achieving the above object, the technical scheme that the utility model is taked is:
A fluid infusion structure, comprise fluid reservoir, flow gauge and horizontal pipeline, described flow gauge is arranged at described fluid reservoir rear end, and described horizontal pipeline is arranged at described flow gauge rear end.It is characterized in that: described fluid reservoir is higher than described horizontal pipeline, and described horizontal pipeline is higher than described flow gauge.Owing to have employed this structure, liquid can be full of in guaranteed flow meter inside always, thus improve its measuring accuracy.
As preferably, the internal diameter of described flow gauge rear end pipeline is less than the internal diameter of described flow gauge front-end pipelines.
Owing to have employed technique scheme, the beneficial effects of the utility model comprise:
Because the horizontal pipeline of flow gauge rear end is higher than flow gauge, so immediately when stopping fluid infusion, still can be full of solution all the time in guaranteed flow meter inside, doing so avoids the internal voids owing to stopping fluid infusion causing and bubble, when making next fluid infusion, flow gauge can be operated in optimum condition, thus improves the precision of whole fluid infusion structure.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the device structure schematic diagram of the utility model embodiment;
Reference numeral: 1-fluid reservoir, 2-flow gauge, 3-horizontal pipeline.
Embodiment
Below in conjunction with example, the utility model is described in detail.
Specific embodiment is only to explanation of the present utility model; be not to restriction of the present utility model; those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this instructions, as long as but be all subject to the protection of Patent Law in right of the present utility model.
Embodiment:
As shown in Figure 1, fluid infusion structure comprises fluid reservoir 1, flow gauge 2 and horizontal pipeline 3, and be provided with a valve below fluid reservoir 1, external control system controls the break-make of solution in pipeline by the switch controlling this valve, arrange flow gauge 2 below valve, it is turbine rotor formula flowmeter.Flow gauge 2 rear end arranges one section of U-tube road, then connects horizontal pipeline 3, arranges downward pipeline for technology groove fluid infusion after horizontal pipeline 3.In addition, the internal diameter of flow gauge 2 rear end pipeline is less than the internal diameter of its front-end pipelines.
Its course of work is as follows, and during normal fluid infusion, control system is to valve command, and valve open, solution flows through flow gauge 2 and horizontal pipeline 3 from fluid reservoir 1 successively through lower pipeline, finally enters the technology groove needing fluid infusion.When the liquor capacity flow through meets technological requirement, control system by-pass valve control is closed, and fluid infusion stops.Now, if do not adopt structure of the present utility model, flow gauge 2 and neighbouring ducted part solution thereof continue to flow into technology groove under gravity, thus make flow gauge 2 inside occur clearance or bubble, when next fluid infusion, these gaps and bubble will affect the precision of flow gauge 2.And if adopt structure of the present utility model, because horizontal pipeline 3 is higher than flow gauge 2, fluid infusion stop after, can solution be full of all the time in flow gauge 2 and neighbouring U-tube road thereof, thus improve the precision of next fluid infusion.In addition, because the internal diameter of flow gauge 2 rear end pipeline is less, the solution return advantageously after preventing fluid infusion from stopping.
