Specific embodiment
A kind of specific embodiment of sampling apparatus of the utility model is further detailed below in conjunction with accompanying drawing.
The utility model provide a kind of sampling apparatus, can for several on-line monitoring equipment provide needed for water sample, its lead To include sampling cup cup 10 and cup lid 11, the multiple openings 101 being opened on sampling cup, 102,111,112,113,114, 115th, from sampling cup begin through each it is described opening extend pipeline 20,21,22,23, connect each pipeline relative sample cup The other end washer bottle 30, keep sample bottle 31.
On the sampling apparatus cup lid 11 have at least 4 be used for online equipment water sample pipe 21 insertion openings 111,112, 113rd, 114 and plug connection washer bottle 30 pipeline 22 opening 115, the opening 101 on the side of the cup 10 is connected to excessive Flow tube 20, bottom side is provided with water-sampling pipeline, and pulse pump 51 is provided with the pipeline of connection washer bottle 30, can be by washer bottle 30 In cleaning agent injection sampling cup 10.
The opening 102 opened up on the bottom of the cup 10 connects the water-sampling pipeline, is respectively arranged with water-sampling pipeline The 2/2-way valve 40 of break-make is controlled, providing peristaltic pump 50, the two-position three-way valve 41 of power, wherein two-position three-way valve 41 connects respectively Connect keep sample bottle 31 and the water inlet/outlet pipeline 23.
The sampling cup uses the acrylic material of long service life, and weather-proof and acid-proof alkaline is good, and transparency is high, is easy to Observe the accumulation of pollutants degree of sampling cup inwall.
Have on the sampling cup cup lid 11 at least 4 openings 111,112,113,114 with diameter greater than online equipment Water sample pipe diameter 1mm or so, can both ensure that water sample tube capacity easily inserts sampling cup hole, can make between water sample pipe and hole again There is enough frictional force, fixed water sample pipe inserts the position of hole.Compared with using lock-on connection, it is simple excellent with plug Point.
The overflow pipe 20 plugged on the side of the sampling cup cup 10 it is straight with diameter greater than water inlet/outlet pipeline 23 Footpath, it is ensured that sampling cup inside aqueous humor position is in a safe condition.
The normal-closed end of the two-position three-way valve 41 connects the bottle 31 that keeps sample, and normally opened end connects water inlet/outlet pipeline 23.Work as measurement During process exception, equipment control software is performed and kept sample function, by control 2/2-way valve 40, two-position three-way valve 41 break-make with And the rotation of peristaltic pump 50, the water sample sampled in cup 10 is persisted in the bottle 31 that keeps sample.The bottle 31 that keeps sample can be built in In micro refrigerator (not shown), extend the water sample shelf-life, it is ensured that return the reliability for surveying result.
The concrete operations of the utility model sampling apparatus are described below by way of specific sampling flow.
Water acquisition:On-line monitoring equipment control 2/2-way valve 40 is opened, the connection water inlet/outlet pipeline of two-position three-way valve 41 23, the lifting water sample while peristaltic pump 50 turns clockwise.Water sample passes through water inlet/outlet pipeline 23, two-position three-way valve 41, peristaltic pump 50th, 2/2-way valve 40 enters in sampling apparatus cup 10.Water sample full of after cup 10, from overflow pipe 20 overflow, each by beginning The sampling pipe of on-line monitoring equipment starts sampling.
