The automatic resampling filter device of water quality
Technical field
The utility model relates to the water purification equipment field, specifically the automatic resampling filter device of water quality.
Background technology
The filter of water quality sampling use at present is easy to stopped up by the impurity in the water; The workman needs regularly the water sample filter to be cleared up and overhauled, and not only the water sample filter effect is undesirable, and the service life of whole filter is short; Maintenance cost is high; Workman's working strength is also quite big, has influenced the operate as normal of water sampling, has reduced operating efficiency.
Summary of the invention
The technical assignment of the utility model is to above weak point, provide a kind of simple in structure, production cost is low, be easy to process, the automatic resampling filter device of water quality of environmentally safe.
The utility model solves the technical scheme that its technical problem adopted: the automatic resampling filter device of this water quality comprises water inlet pipe, outlet pipe and water sample pipe; The pipeline that is communicated with between water inlet pipe and the outlet pipe is provided with filter one and filter two; Pipeline between filter one and the filter two is communicated with the water sample pipe; Water inlet pipe is provided with motor-driven valve one and motor-driven valve two, and outlet pipe is provided with motor-driven valve three and motor-driven valve four.
Described outlet pipe is provided with the hand-operated valve one that is used for regulating pressure, and the water sample pipe is provided with the hand-operated valve two that is used for regulating pressure.
The automatic resampling filter device of the water quality of the utility model is compared with prior art; Have reasonable in design, simple in structure, be easy to characteristics such as processing, easy to use, good filtration effect, long service life, maintenance cost is low, effectively reduced working strength of workers.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
The automatic resampling filter device of the water quality of the utility model; Its structure comprises water inlet pipe 1, outlet pipe 2 and water sample pipe 3; The pipeline that is communicated with between water inlet pipe 1 and the outlet pipe 2 is provided with filter 1 and filter 28; Pipeline between filter 1 and the filter 28 is communicated with water sample pipe 3, and water sample pipe 3 is provided with the hand-operated valve 2 11 that is used for regulating pressure; Water inlet pipe 1 is provided with motor-driven valve 1 and motor-driven valve 26, and outlet pipe 2 is provided with motor-driven valve 35 and motor-driven valve 4 10, also is provided with the hand-operated valve 1 that is used for regulating pressure on the outlet pipe 2.
During work, water pump is gathered water sample and is got into by water inlet pipe 1, and motor-driven valve 1 is opened with motor-driven valve 4 10, and motor-driven valve 26 cuts out with motor-driven valve 35, filter one 7 filtrations this moment, and filter 28 is in the state that is rinsed; Next time, motor-driven valve 26 was opened with motor-driven valve 35 during water sampling, and motor-driven valve 1 cuts out with motor-driven valve 4 10, filter 28 filtrations this moment, and filter 1 is in the state that is rinsed; When each sampling pump started, the state of motor-driven valve will according to above-mentioned variation once keep periodic duty.
Automatic its processing and fabricating of resampling filter device of the water quality of the utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
