Abstract
The utility model discloses a new ration ring quantitative system, including two three solenoid valve, be equipped with liquid flow hole NO, NC and switch COM on three solenoid valve, connect with first connecting pipe between the NO on two solenoid valves, connect with the second connecting pipe between the NC on two solenoid valves. The utility model discloses because the more easy function that realizes quantitative ring of quantitative system that adopts two three solenoid valve to constitute, therefore simple structure, the trouble is few, convenient operation, and quantitative system is stable, the ration is accurate.
Description
Technical field
The utility model relates to a kind of environmental protection analytical instrument for liquid quantitative.More particularly, the utility model relates to a kind of new quantitative loop quantitative system.
Background technology
For sample and reagent to be dispensed in reaction vessel and the absorbance measuring the reaction liquid generated in reaction vessel is known with the analyser analyzing sample.Such analyser comprises the photometric measurer with light source and light receiver.Light source irradiates light to the reaction vessel that reaction liquid is housed, and light receiver calculates absorbance, to analyze sample based on through the reaction liquid in reaction vessel and the light quantity that received by light receiver.
The quantitative loop that current environmental protection analytical instrument adopts is the quantitative system of 6 logical valves, but 6 logical valves need motor to drive, and equipment is complicated, and cost is high, and fault is many, and operation is difficult.
Utility model content
The utility model, in order to overcome the defect of prior art, discloses a kind of new quantitative loop quantitative system.
An object of the present utility model is, provide a kind of structure simple, the quantitative system be made up of two three-way solenoid valves, structure is simple, and fault is few, easy to operate new quantitative loop quantitative system.
In order to realize according to these objects of the present utility model and other advantage, provide a kind of new quantitative loop quantitative system, it is characterized in that, comprise two three-way solenoid valves, described three-way solenoid valve is provided with two liquid stream ports and switch, described two liquid stream ports are respectively first liquid communication port and second liquid communication port, connect between the first liquid communication port on two solenoid valves with the first connecting pipe, connect between the second liquid communication port on two solenoid valves with the second connecting pipe.
Preferably, described first connecting pipe and the second connecting pipe is bonding or in the first liquid communication port that is socketed in two three-way solenoid valves and second liquid communication port.
Preferably, the size of described two three-way solenoid valves is identical with function.
Preferably, the length of described first connecting pipe and the second connecting pipe depends on quantitative volume.
The utility model at least comprises following beneficial effect: the function of the utility model owing to adopting the quantitative system of two three-way solenoid valve compositions to be relatively easy to achieve quantitative loop, therefore structure is simple, fault is few, easy to operate, and quantitative system is stable, quantitatively accurate.
Part is embodied by explanation below by other advantage of the present utility model, target and feature, part also will by research and practice of the present utility model by those skilled in the art is understood.
Accompanying drawing explanation
Fig. 1 is the structural representation of the new quantitative loop quantitative system of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to instructions word to make those skilled in the art.
Should be appreciated that used hereinly such as " to have ", other element one or more do not allotted in " comprising " and " comprising " term or the existence of its combination or interpolation.
Fig. 1 shows according to a kind of way of realization of the present utility model, comprising two three-way solenoid valves 1, described three-way solenoid valve 1 is provided with liquid stream port NO, NC and switch COM, connect with the first connecting pipe 2 between NO on two solenoid valves 1, connect with the second connecting pipe 3 between the NC on two solenoid valves 1.
Described first connecting pipe 2 and the second connecting pipe 3 bonding or be socketed on two three-way solenoid valves 1NO, NC.
The size of described two three-way solenoid valves 1 is identical with function.
The length of described first connecting pipe 2 and the second connecting pipe 3 depends on quantitative volume.
Using method of the present utility model: two solenoid valve Simultaneous Switchings, when electromagnetism closes and no power, the pipeline that liquid connects from NO flows through, and is energized when solenoid valve leaves, and the pipeline that liquid connects from NC flows through.When needing the liquid of quantitative NO pipe, only liquid need be allowed to flow through NO pipe, rear to two solenoid valves, open solenoid valve, now the liquid of NO pipe is just lockable, then the liquid of emptying pipeline, and the liquid that shut electromagnetic valve discharges NO gets final product the liquid of quantitative NO.
Here the number of devices illustrated and treatment scale are used to simplify explanation of the present utility model.Application of the present utility model, modifications and variations be will be readily apparent to persons skilled in the art.
As mentioned above, according to the utility model, due to the function adopting the quantitative system of two three-way solenoid valve compositions to be relatively easy to achieve quantitative loop, therefore structure is simple, and fault is few, easy to operate, and quantitative system is stable, quantitatively accurate.
Although embodiment of the present utility model is open as above, it is not restricted to listed in instructions and embodiment utilization.It can be applied to various applicable field of the present utility model completely.For those skilled in the art, can easily realize other amendment.Therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
