Background technology:
At present, about the application study of nature flow rate of water flow, relate generally to the research that comes aspects such as research environment pollution and waters ecosphere by simulating nature environment current change in flow, and its scope of application is very extensive in the laboratory.Wherein, as the important component part of this simulating lab test, the experimental water circulating system has become a very important link that influences experimental result in the research.Therefore accurate flow rate of water flow control system and water environment factor controllable system are installed in water circulation system, just become particularly important, this plays an important role to whole experimental study analog result.But in the existing water circulation system, the change of flow velocity is mainly regulated by flow control valve, because common flow control valve accuracy is not high, can only have the coarse adjustment of deviation slightly to current, and testing required flow velocity can not remain under the stable duty, to such an extent as to can't satisfy the high scientific experiment of those accuracy demands,, also reduce the science and the confidence level thereof of experimental research achievements for whole experimental study has brought very big harmful effect.
The utility model content:
The utility model is at the experimental water circulating system in the present use, adopt flow control valve to regulate flow velocity, to those come the experiment of research environment pollution and waters ecosphere in the laboratory by simulating nature ambient water change in flow, because common discharge control valve convection current speed control system accuracy is not high, flow velocity is in stable duty in can not keeping testing, so that can't satisfy a series of problems such as the demanding scientific experiment of many accuracy, carry out rational improvement, thereby reached the purpose that reduces cost and improve practicality.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of controllable environment factor speed change water circulation system, described water circulation system mainly comprises water pipe, storage tank and water pump; Also be provided with one in the described water circulation system and take into account the intelligence control system that adjusting apparatus assembles by electrical adjustment valve, flow, described intelligence control system is connected on the described water pipe by electrical adjustment valve and flow meter; On the tank inner wall of described storage tank, also be provided with the envirment factor measuring instrument that is used to measure the controllable environment factor.
The utility model energy pinpoint accuracy controlled water flow speed, and required flow velocity remains under stable equilibrium's the duty in can continuing to test, and can regulate the controllable environment factor in real time simultaneously, satisfies the each side requirement of experiment for the water circulation environment.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, be a kind of structural representation of variable speed controllable water circulation system, comprise water pipe 3, storage tank 1, water pump 2 and intelligence control system, and intelligence control system is assembled by flow meter 4, electrical adjustment valve 5 and automation control apparatus 6; Water pump 2 links to each other with the water inlet port of water pipe 3, and by water pipe 3 respectively with intelligence control system in electrical adjustment valve and flow meter link to each other successively, and the water outlet port of water pipe one side communicates with storage tank, so just formed one group of water-flow circuit.In the utility model, but storage tank 1 can adopt the water tank of the heating and cooling after simple water tank comparatively commonly used or the process simple modifications, such benefit is to improve greatly the utilization rate again to original experimental facilities, thereby reduce the unnecessary experiment spending of experiment, and on the basis of original water tank, only be used for measuring the thermometer 8 of the water circulation system controllable environment factor in the wall assembling within it, a series of measurement mechanisms such as PH measuring instrument 9, just can satisfy in the experiment the water environment real time monitoring function, the experimenter can be adjusted in the controllable environment factor in the experiment controlled range timely; Also can use original water pump in original laboratory as for water pump 2, select some water supply commonly used with pvc pipe or iron pipe and water pipe 3 is main.Because traditional flow control valve is not high for the flow velocity control accuracy of experimental water, also be difficult to flow velocity is kept on the stationary value for a long time, to such an extent as to can not satisfy in the experiment requirement for the accuracy aspect.For this reason, the utility model has adopted an intelligence control system that has valve mechanism, because this class intelligence control system kind is more on the market, only need choose a the getting final product of requirement of experiment of satisfying.The utility model is owing to be to be used for indoor environment simulation experiment, only need afterbody in the water circulation system of being formed by electrical adjustment valve 5 in water pump 2, water pipe 3, the intelligence control system and flow meter 4, connect a last test tank that is used to test 7 by water pipe 3, the requirement in the time of just can satisfying experiment.
During use, only need the water inlet switch 11 and the drainage switch 10 of control storage tank one side earlier, make in storage tank 1, to hold and satisfy enough experimental waters.Because being mainly used in by simulating nature ambient water change in flow research environment, pollutes and the waters ecosphere by this experimental facilities, start measuring apparatuss such as the thermometer 8 installed on the inwall of water tank 1, pH value measuring instrument 9 for this reason, just can satisfy controllable environment factor control measurement timely, be convenient to the adjusting that the experimenter carries out the controllable environment factor water circulation system in the experiment.Start water pump 2 then, make water by pipeline 3 flow through intelligence control system and experimental water district 7, the last drain hole of Water District 7 by experiment enters in the water tank 1, forms the required water circulation system of experiment.Water pump 2 can extract an amount of water according to the selected certain power of actual conditions in use, and intelligence control system is by flow meter 4, automation control apparatus 6, electrical adjustment valve 5 is formed, when current during through intelligence control system, operating personnel can set the flow velocity of experimental water stream in advance on automation control apparatus 6, control the suitable size of valve regulated of electrical adjustment valve 5 then by electronic signal, just can be under the prerequisite of controlled water flow flow velocity, flow rate of water flow is remained in the stable duty, flow meter 4 then can show flow rate of water flow, thus the real time data information that makes the experimenter obtain testing.And whole experimental implementation is simple, control flow rate of water flow in the experiment by intelligence control system, and can regulate the controllable environment factor in real time, can be good at satisfying the experiment needs, create an experimental situation more true to nature, thereby improved the accuracy rate of experimental data greatly, having reduced it influences the inessential factor of experimental result.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
