Abstract
The utility model discloses a circulation type pH meter sampling device which comprises a sample splitting tube, a pH meter and a sample circulation tank, wherein a sampling tube is arranged at the lower part of one side of the sample circulation tank; the sampling tube is connected with a production system; an overflowing tube is arranged at the upper part of the other side of the sample circulation tank; the overflowing tube is connected with the production system; the pH meter is connected with the top part of the sample circulation tank; a sampling valve is arranged at the bottom of the sample circulation tank. The device has the advantages of practicability, timeliness, simplicity in operation, convenience in maintenance and the like, the liquid level inside the sample circulation tank is kept stable, the liquid level inside the sample circulation tank is prevented from dropping down when the liquid supply is stopped, the stable flowing of the sample in the automatic on-site sampling process is ensured, the liquid level is stable, an on-line pH meter electrode is prevented from being damaged when being exposed in air, and normal application of the on-line pH meter is ensured.
Description
Technical field
The utility model is a kind of flow type pH meter sampling apparatus, is applicable to the industry liquid material index process detection technique fields such as chemical industry, metallurgy.
Background technology
PH value on line real-time monitoring is the important index monitoring means of industry such as current chemical industry, metallurgy.But because liquid material in chemical industry, metallurgical production process is often because corrosivity is strong, easily crystallization, or because liquid fluctuating is large, easily flood pH meter signal wire or electrode is exposed in air, cause electrode failure, display distortion, and use after a period of time, on electrode, be covered with crystallized stock, have a strong impact on the use of pH meter electrode.
Utility model content
The purpose of this utility model be to provide a kind of under complicated operating mode the sampling apparatus of pH meter, the maintenance of pH meter is simplified, in daily servicing, no longer to producing, impact.
The purpose of this utility model is achieved through the following technical solutions.
A kind of flow type pH meter sampling apparatus, comprise sample isocon, pH meter, sample flow cell, described sample flow cell one side lower part arranges sampling pipe, described sampling pipe is connected with production system, described sample flow cell opposite side top arranges run-down pipe, described run-down pipe connects production system, and described sample flow cell top connects pH meter, and described sample flow cell bottom arranges sample valve.
On sampling pipe between described sample flow cell and production system, establish a sample diverting valve.
Described sample diverting valve is that teflon is the butterfly valve of liner.
The material of described sample flow cell is CPVC resin.
Described sample valve is CPVC resin ball valve.
Of the present utility model have practicality, an advantage such as real-time, simple to operate, easy to maintenance, can make liquid level in sample flow cell continue held stationary, when feed flow stops, sample flow cell liquid level does not decline, can automatically in sampling process, guarantee sample steady flow at the scene, liquid level is steady, can avoid online pH meter electrode to be exposed in air and the damage causing guarantees that online pH meter normally uses.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of flow type pH meter sampling apparatus, comprise sampling pipe 2, pH meter 6, sample flow cell 3, sample flow cell 3 one side lower parts are installed U-shaped sampling pipe 2, sampling pipe 2 is connected with production system 8, on sampling pipe 2 between sample flow cell 3 and production system 8, sample diverting valve 1 is installed, wherein sample diverting valve 1 for liner can acid and alkali-resistance solution corrosion teflon be butterfly valve.Run-down pipe 7 is installed on sample flow cell 3 opposite side tops, and run-down pipe 7 connects production system 8, and the sample of shunting is delivered to sample flow cell 3 from production system 8 pressure, then is back to production system 8 through the run-down pipe 7 of sample flow cell 3.Sample flows into from sample flow cell 3 bottom inlets through sampling pipe 2, from sample flow cell 3 top run-down pipes 7, flows out.Sample flow cell 3 tops connect pH meter 6 by joint flange 4, and sample flow cell 3 bottoms arrange sample valve 5, and for sample examination, sample valve 5 is CPVC resin ball valve.It installs sampling apparatus, and shunting sample is delivered to sampling apparatus from producing system pressure, then is back to production system through sampling apparatus run-down pipe,
The utility model practicality, real-time, simple to operate, easy to maintenance, can make the interior liquid level of sample flow cell 3 continue held stationary, and when production system 8 is stopped, sample flow cell 3 liquid levels do not decline, and can avoid online pH meter 6 electrodes to be exposed in air.
