During use, valve body 9 is installed near the water source that needs to detect, the water sample that will need with pipeline to detect is connected with water inlet 12, freeing port 13 is connected with blowoff basin, and during operation, programming controller 16 accessory drives 8 rotate, moving plate 3 rotations in the middle of driving, when going to the corresponding position of locating device 7, locating device 7 sends signal and gives program, and accessory drive 8 stops.When stopping the time of setting in this position, programming controller 16 accessory drive 8 again rotates, and stops in the position of needs by locating device 7 accessory drives 8, thereby realizes required function.
Below by embodiment each duty is described.
When needs when displacement flushing, as shown in Figure 6, the through hole 31 of middle moving plate and the through hole of last stator 21 and down the through hole 41 of stator communicate, the through hole 32 of moving plate communicates with the through hole 45 of stator under the through hole of last stator 25 reaches.Because the through hole 41 of following stator communicates with water inlet 12, through hole 45 communicates with freeing port 13, the through hole 21 and 25 of last stator 2 all communicates with hybrid chamber 10.Like this, water sample in the pipeline enters down the through hole 41 of stator 4, the through hole 31 of middle moving plate 3, the through hole 21 of last stator 2 through water inlet 12, flow to hybrid chamber 10, at this moment, the non-return valve 11 of hybrid chamber 10 cuts out, the through hole 45 of the through hole 32 of the through hole 25 of stator 2, middle moving plate 3, following stator 4 on current are flowed through is discharged by freeing port 13.The water sample that is about to retain in the pipeline is discharged by freeing port 13, and hybrid chamber 10 usefulness water samples are cleaned.
When the needs emptying, as shown in Figure 7, the through hole 31 of middle moving plate 3 communicates with the through hole 42 of through hole of last stator 2 22 and following stator 4, and the through hole 32 of middle moving plate 3 does not communicate with the through hole of last stator 2 and following stator 4.At this moment, the through hole 42 of the through hole 22 of the stator 2 on warp under the effect of gravity of the mixed liquor in the hybrid chamber 10, the through hole 31 of middle moving plate 3, following stator 4 is discharged by freeing port 13 at last; Simultaneously, the non-return valve 11 of hybrid chamber 10 is opened, and air enters hybrid chamber 10, so that the liquid in the hybrid chamber 10 is thoroughly got rid of.
When needs advanced reagent, as shown in Figure 8, the through hole 31 on the middle moving plate 3 communicated with the through hole 43 of through hole of last stator 2 23 and following stator 4, and the through hole 32 of middle moving plate 3 does not communicate with the through hole of last stator 2 and following stator 4.Because the through hole 23 of last stator 2 communicates with reagent bottle 1, at this moment, the through hole 31 of the moving plate 3 in the middle of the through hole 23 of last stator 2 enters of the reagent in the reagent bottle 1, because reagent has certain viscosity, and the through hole 43 of following stator 4 is very little (can only to be gone out by air, reagent can not flow out), like this, the through hole 31 of moving plate 3 in the middle of reagent can be full of in the regular hour fully.
When needs water inlets sample, as shown in Figure 9, the through hole 31 on the middle moving plate 3 and the through hole of last stator 2 24 and down the through hole 44 of stator 4 communicate, the through hole 32 of middle moving plate 3 does not communicate with the through hole of stator 4 under last stator 2 reaches.Because the through hole 44 of following stator 4 communicates with water inlet 12, therefore, water sample enters hybrid chamber 10 through the through hole 44 of following stator 4, the through hole 31 of middle moving plate 3, the through hole 24 of last stator 2, the reagent of the through hole 31 of moving plate 3 is finished and is brought hybrid chamber 10 mixing in the middle of entering in the time of will advancing reagent, and the non-return valve 11 of hybrid chamber 10 is opened, and air is discharged thus, after water sample is full of, under the effect of buoyancy and pressure, non-return valve 11 cuts out, and water inlet sample and water sample were finished with mixing of reagent.
When needs detected, as shown in figure 10, through hole 31 on the middle moving plate 3 and through hole 32 did not communicate with arbitrary through hole of last stator 2 and following stator 4, so do not form runner.At this moment, the radiating portion of pick-up unit sends signal, passes mixed liquor, and whether the receiving trap 15 of pick-up unit is received the mixed liquor color signal that transmits, and changes into electric signal, transfers to program, qualified by the programmed decision water sample.
After detection is finished, be parked in this position, wait routine controller 16 sends and detects instruction next time.Mixed liquor is easy to be bonded on the valve body 9 and during next time accuracy of detection of influence, can goes to flushing displacement, emptying state again after the complete detection of program, at last program is rested on emptying state.When detecting beginning next time, after programming controller 16 accessory drives 8 oppositely go to the flushing displacement position again, again to emptying, advance reagent, positions such as sample, detection, flushing displacement, emptying intake.
Figure 11 to Figure 13 is that the last stator 2 of embodiment 2, middle moving plate 3 reach the upward view of stator 4 down, and the mixed liquor that this embodiment is applied to reagent and water sample sticks on the valve body 9 easily, the situation of the precision when influence detects once more.
The formed process flow diagram of present embodiment will increase once flushing displacement and emptying, promptly have seven process flow diagrams: flushing displacement (Fig. 6, the water sample that is detained in the washing pipe road is discharged, and use the water sample that to detect to clean hybrid chamber 10 and runner), emptying (Fig. 7, the liquid of emptying hybrid chamber 10), advance reagent (Fig. 8, the through hole of moving plate 3 in the middle of reagent enters), water inlet sample (Fig. 9, water sample is brought into hybrid chamber 10 with reagent), detect (Figure 10, detect the change color of mixed liquor), flushing displacement (Fig. 6, with water sample mixed liquor is discharged from freeing port 13), emptying (Fig. 7, the mixed liquor in the emptying hybrid chamber 10).
