Abstract

The utility model discloses a countercurrent sampling device for water quality online automatic monitoring equipment. The countercurrent sampling device comprises a water inlet pipeline (6), a sampling pipeline and a water outlet pipeline (7), wherein the sampling pipeline is communicated with the outlet of the water inlet pipeline and the inlet of the water outlet pipeline through a t-branch pipe (5). The countercurrent sampling device has the beneficial effects that a countercurrent suck-back sampling mode is adopted, so when the device is used for collecting water samples, fine particulate matters and suspended matters in the water samples cannot easily enter the sampling pipeline under the actions of pressure in the water current direction and the gravity, in such a way, the sampling pipeline is smoother without being easily blocked; a manual ball valve is additionally arranged on the upper end of the water inlet of the water outlet pipeline, so sampling liquid level in the pipeline and the water flow speed can be debugged according to the magnitude of the pressure of the supplied water flow, and the sampling is convenient; and the water inlet end and the water outlet end are movably connected through movable joints, so that the installation of a water quality online monitor is convenient.

Description

The adverse current sampler that is used for water quality online auto monitoring equipment
Technical field
The utility model relates to water quality on-line monitoring instrument or system, relates in particular to the adverse current sampler for water quality online auto monitoring equipment.
Background technology
Water quality on-line monitoring instrument (or system) is the instrument that the water quality of main basin emphasis section water body and various supervision sewage draining exit are monitored.Monitor of a great varietyly, COD, ammonia nitrogen, total phosphorus and each metal ion species etc. are arranged.Water quality on-line monitoring instrument (or system) in the course of the work, need carry out response measurement by sampling pump extraction water sample and the reagent of self, in the process that extracts water sample, in the current that the water supply suction pump provides in the process that supplies water, usually contain a large amount of fine particle things (as fine deposit, suspension etc.), be easy under the pressure and flow action of water supply suction pump, be pressed in the sampling tubule, fine grained in the long-term work tubule is piled up, cause sampling line to stop up easily, cause instrument sampling fault, and then make the equipment fluctuation of service.
The utility model content
The technical problems to be solved in the utility model to be existing water quality on-line monitoring instrument have in the process that extracts water sample a large amount of fine particle things are pushed down in the sampling tubule at the pressure of water supply suction pump and flow action and cause sampling line to stop up, cause instrument sampling fault, and then make the equipment fluctuation of service, a kind of adverse current sampler for water quality online auto monitoring equipment is provided for this reason.
The technical solution of the utility model is: be used for the adverse current sampler of water quality online auto monitoring equipment, it comprises inlet pipeline, sampling line and outlet pipeline, and described sampling line is connected with the outlet of inlet pipeline and the import of outlet pipeline by three-way pipe.
Sampling line described in the such scheme comprises sampling water pipe, sample connection, plug and sample connection seat, and described sampling water pipe passes sample connection, plug, sample connection seat and three-way pipe successively and stretches into outlet pipeline.
The water pipe of sampling described in the such scheme is polyfluortetraethylene pipe.
Plug described in the such scheme is the UPVC pipe.
The water delivering orifice place of the water inlet of inlet pipeline described in the such scheme and outlet pipeline is equipped with the water pipe articulation.
Be provided with manual ball valve near described three-way pipe place on the outlet pipeline described in the such scheme.
The beneficial effects of the utility model are to adopt adverse current suck-back sampling mode, make instrument when gathering water sample, fine particle in the water sample and suspension are difficult for entering the sampling water pipe under water (flow) direction pressure and gravity effect, make sampling line more smoothness be not easy to be plugged; A manual ball valve has been set up in the water inlet upper end of outlet pipeline, can be according to sampling liquid level and water velocity in the big minor mode pipeline of water supply water flow pressure, and convenient sampling; Water inlet end all adopts the articulation loose joint to be connected with the water side, has made things convenient for the installation of water quality on-line monitoring instrument.
Description of drawings
Fig. 1 is the utility model synoptic diagram;
Fig. 2 is A place enlarged drawing among Fig. 1;
Fig. 3 is B place enlarged drawing among Fig. 1;
Among the figure, 1, the sampling water pipe, 2, sample connection, 3, plug, 4, the sample connection seat, 5, three-way pipe, 6, inlet pipeline, 7, outlet pipeline, 8, the water pipe articulation, 9, manual ball valve.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model comprises inlet pipeline 6, sampling line and outlet pipeline 7, and described sampling line is connected with the outlet of inlet pipeline and the import of outlet pipeline by three-way pipe 5.
Inlet pipeline, outlet pipeline and three-way pipe can all adopt the UPVC pipe, the water inlet of inlet pipeline and the water delivering orifice of outlet pipeline are equipped with water pipe articulation 8, this water pipe articulation can be the UPVC pipe, can certainly be other material, has made things convenient for the installation of water quality on-line monitoring instrument like this.
The corner of inlet pipeline and outlet pipeline can adopt 90 ° of elbows to be connected, this elbow can be UPVC pipe or other material, be provided with manual ball valve 9 near the three-way pipe place on the outlet pipeline, this manual ball valve material can be UPVC or other material, and the plug 3 of sampling line can be UPVC or other material.The UPVC pipe be a kind of be raw material, the not plastic pipe of plasticizer-containing with the Corvic.It has corrosion resistance and the good advantage of flexibility, thereby is specially adapted to water supply network.
Sampling water pipe 1 can be polyfluortetraethylene pipe, and the material of sample connection seat 4 can be teflon, and teflon is a kind of artificial synthesized polymer material that has used fluorine to replace all hydrogen atoms in the tygon.This material has the characteristics of antiacid alkali resistant, anti-various organic solvents, is dissolved in all solvents hardly.Simultaneously, teflon has corrosion resistant characteristics, and its friction factor is extremely low, so can do after the lubrication, also becomes the desirable coating of easy clean pot and water pipe internal layer.
Sampling line comprises the sampling water pipe in the utility model, sample connection 2, plug and sample connection seat, teflon sample connection cover for seat is gone on the end face of sampling line, hold circular hole successfully at plug then, be inserted in teflon sample connection seat again, at last with gluing being connected on the water pipe end face of feedwater, insert the sampling water pipe, use the sample connection fixed seal connection, the end of sampling water pipe will pass sample connection successively, plug, sample connection seat and three-way pipe extend in the outlet pipeline, sample connection, plug, sample connection seat and three-way pipe also can adopt other connected mode, as long as can reach the purpose of sealing.
Water (flow) direction as shown in the figure when the utility model used, the make-up pump current enter the sampling line water inlet, discharge from the outlet pipeline water delivering orifice after the adjusting through pipeline guiding and manual ball valve, the water pipe of will taking a sample then injects the sample connection fixed seal connection and enters outlet pipeline inside, makes instrument extract water sample adverse current suck-back and enters instrument.
