Abstract
A kind of automatic water sampling system for real-time water quality monitoring, placement current limliting post in water inlet pipe, it is first to reduce water flow pressure, hydraulic pressure is accurately adjusted by pressure regulator valve again, introduce the water into upper left end opening, in the transparent return in lower end, observable in-pipe flow mobility status, it is determined that hydraulic pressure is adjusted into required atmospheric pressure, keep the voltage stabilizing state of hydraulic pressure in return, again tubule is drawn from detection pipe to enter at opening, be introduced into water sample in detection pipe and detected by the negative pressure produced using detection pipe, realize the full-automatic operation of water sampling, reduce the manual intervention in detection, reduce the fraud chance in detection, improve the accuracy and versatility of detection.
Description
Technical field
The present invention relates to automatic water sampling field, more particularly to a kind of automatic water sampling system for real-time water quality monitoring.
Background technology
At present, it is required to be detected by water pump extraction water sample on time for real-time water quality monitoring.But the pressure of pumping for water pump is universal very big, it is impossible to be directly inputted in detector, it is necessary to carry out reduced pressure treatment；Also to guarantee that the water sample that different periods are extracted is input in detector automatically simultaneously.
The information for being disclosed in the background section is merely intended to increase understanding to general background of the invention, and in being not construed as recognizing or imply in any form that the information structure has been the prior art well known to persons skilled in the art.
The content of the invention
It is an object of the invention to provide a kind of automatic water sampling system, can be by real-time water quality monitoring requirement, the water sample decompression that different periods are extracted is input in detector, in the case where manual intervention is not needed, it is ensured that the full-automatic operation of water quality monitoring.
The technical solution adopted for the present invention to solve the technical problems is：By current limliting post, it is first to reduce water flow pressure, hydraulic pressure is accurately adjusted by pressure regulator valve again, in introducing the water into the transparent return in upper left end opening, lower end, observable in-pipe flow mobility status, it is determined that hydraulic pressure is adjusted into required atmospheric pressure, keep the voltage stabilizing state of hydraulic pressure in return, draw tubule from detection pipe again to enter at opening, be introduced into water sample in detection pipe and detected by the negative pressure produced using detection pipe.
The beneficial effects of the invention are as follows：By repeatedly adjustment intake pressure, help to keep automatically the stabilization of hydraulic pressure in return upper end open without special instrument, for the automatic feeding water of detector provides precondition, and keep the continuity of water sample extraction, realize the full-automatic operation of water sampling, the manual intervention in detection is reduced, the fraud chance in detection is reduced, the accuracy and versatility of detection is improved.
Brief description of the drawings
Fig. 1 is axonometric drawing of the invention.
1. water inlet pipe in figure, 2. current limliting post, 3. pressure regulation ball valve, 4. water inlet elbow, 5. return, be 6. open pore, 7. transparent pipeline, 8. water exit elbow, 9. outlet pipe, 10. drinking-water pipe, 11. detection pipes.
Specific embodiment
Specific embodiment of the invention is described in detail with reference to the accompanying drawings and examples, it is to be understood that protection scope of the present invention is not limited by specific embodiment.
In Fig. 1, water inlet pipe（1）Lower end disposes a current limliting post（2）, force to allow the High-Pressure Water that water pump is sent to be flowed into by aperture, greatly reduce the pressure of current, while in water inlet pipe（1）Middle-end disposes a pressure regulation ball valve（3）, the current for having depressurized can again be finely tuned pressure, current pass through water inlet elbow afterwards（4）By water inlet pipe（1）Into return（5）.Return（5）Left upper end leaves an opening pore（6）, there is one section of transparent pipeline lower end（7）, the situation of current when being available for observing pressure regulation.When pressure regulation is to an approximate atmospheric pressure, current can be in transparent pipeline（7）In slowly flow, while according to Pascal's law, atmospheric pressure can be by opening pore（6）Act on whole return（5）In, therefore current can be in water inlet elbow（4）And water exit elbow（5）Place keeps same level, and current can keep stabilization, not spill over.Unnecessary current can be by return（5）Into water exit elbow（8）Flow into outlet pipe（9）Middle outflow.Return（5）Opening pore（6）By drinking-water pipe（10）With detection pipe（11）It is connected.When needing detection water sample, detection pipe（11）Middle generation is that the water sample that may be inhaled corresponding volume enters detection pipe to a proportional negative pressure of atmospheric pressure（11）In.
As a kind of specific embodiment, the current limliting post（2）Can be got by the processing to existing plastic column, can be obtained by Drilling operation in the middle of plastic column.
The foregoing description to specific illustrative embodiment of the invention be in order to illustrate and illustration purpose.These descriptions are not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can much be changed and changed.The purpose of selecting and describing the exemplary embodiment is that certain principles of the invention and its practical application are explained, so that those skilled in the art can realize and utilize a variety of exemplaries of the invention and a variety of selections and change.The scope of the present invention is intended to be limited by claims and its equivalents.
