SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to solve the technical problem that a multiple exhaust design prevents throwing of measuring pump to throw pressure too high, ensures the safe operation of equipment and the sodium hypochlorite dosing system that the water quality of leaving the factory is stable.
In order to solve the technical problem, the utility model discloses the technical scheme who takes is: a sodium hypochlorite adding system comprises a raw liquid tank, wherein the raw liquid tank is connected with a liquid outlet pipeline, and the liquid outlet pipeline is sequentially provided with a first manual valve, a Y-shaped filter, a metering pump, a pressure gauge, a pulse damper, a back pressure valve and a flowmeter; a first return pipeline and a second return pipeline are connected to the liquid outlet pipeline in front of the back pressure valve, a safety valve is arranged on the first return pipeline, an electromagnetic valve is arranged on the second return pipeline, the first return pipeline and the second return pipeline are connected with a fourth return pipeline, and the fourth return pipeline is connected with the raw liquid tank.
In the sodium hypochlorite adding system, the second return pipeline is connected with a third return pipeline, two ends of the third return pipeline are communicated with the second return pipeline, and a third manual valve is arranged on the third return pipeline.
In the sodium hypochlorite adding system, the third return pipeline is connected to the second return pipelines at two ends of the electromagnetic valve.
In the sodium hypochlorite adding system, the liquid outlet pipeline in front of the metering pump is connected with the power water pipeline, and the power water pipeline is provided with the second manual valve.
The utility model discloses sodium hypochlorite dosing system's advantage is:
1. the sodium hypochlorite adding system of the utility model can lead the gas generated by sodium hypochlorite to return to the sodium hypochlorite stock solution tank through the solenoid valve and a fourth return pipeline by additionally arranging the second return pipe and the solenoid valve on the liquid outlet pipeline, and can prevent the adding pressure of the metering pump from being overhigh by exhausting regularly for set time, thereby ensuring the safe operation of equipment and the stability of the quality of the water of the leaving water; simultaneously add third return line, the manual valve of third on the second back flow, the purpose is when the solenoid valve damages, can open the manual valve of third, and the solenoid valve entering second return line can be avoided by the third return line to the gas that sodium hypochlorite produced, then gets back to the stock solution jar through fourth return line, has played the dual insurance effect of exhaust.
2. The utility model discloses sodium hypochlorite dosing system, simple structure, low cost, convenient operation, the maintenance volume is little, can thoroughly solve because of sodium hypochlorite produces gas too much, causes to throw and adds the pressure too high, influences the delivery water quality of water and shortens the life of diaphragm and pulse damper, saves effect such as manual work.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Embodiment 1, as shown in fig. 1, a sodium hypochlorite dosing system includes a raw liquid tank 1, the raw liquid tank 1 is connected to a liquid outlet pipeline 2, and the liquid outlet pipeline 2 is sequentially provided with a first manual valve 3, a Y-type filter 4, a metering pump 5, a pressure gauge 6, a pulse damper 7, a back pressure valve 8, and a flow meter 9; a first return pipeline 12 and a second return pipeline 13 are connected to the liquid outlet pipeline 2 in front of the back pressure valve 8, a safety valve 14 is arranged on the first return pipeline 12, an electromagnetic valve 15 is arranged on the second return pipeline 13, the first return pipeline 12 and the second return pipeline 13 are connected with a fourth return pipeline 17, and the fourth return pipeline 17 is connected with the raw liquid tank 1.
In embodiment 3, as shown in fig. 1, in addition to embodiment 2, the third return line 16 is connected to the second return lines 13 at both ends of the solenoid valve 15.
Embodiment 4, as shown in fig. 1, in addition to embodiment 1, a power water line 10 is connected to the liquid outlet line 2 before the metering pump 5, and a second manual valve 11 is provided on the power water line 10.
The electromagnetic valve 15 can be automatically opened within 1-2h through automatic programming, and is closed within 1-2s after being opened, and gas generated by sodium hypochlorite returns to the sodium hypochlorite raw liquid tank 1 through the second return pipeline 13 and the fourth return pipeline 17; the third manual valve 18 is in a closed state at ordinary times, when the electromagnetic valve 15 cannot be opened or damaged, the third manual valve 18 is opened on site, gas generated by sodium hypochlorite bypasses the electromagnetic valve 15, flows back to the second return pipeline 13 again through the third return pipeline 16 and the third manual valve 18, and is discharged to the sodium hypochlorite raw liquid tank 1 through the fourth return pipeline 17. If the liquid outlet pipeline 2 is blocked and the pressure exceeds the critical safety value set by the safety valve 14, the safety valve 14 can be automatically opened, and the solution flows back to the raw liquid tank 1 through the opened safety valve 14. When system pressure is lower than the set pressure of the back pressure valve 8, the back pressure valve 8 is in a closed state, when the metering pump 5 operates, the system pressure is greater than the set pressure of the back pressure valve 8, the pipeline is connected, liquid passes through the back pressure valve 8, the outlet of the metering pump 5 can have constant pressure through the back pressure valve 8, the output flow is stable, and the siphonage caused by the gravity flow and other effects of the pressure of the raw liquid tank 1 at the outlet of the metering pump 5 is avoided. When the metering pump 5 stops running for a long time or the pipeline has other conditions, the metering pump 5 and the pipeline thereof need to be flushed by water, the second manual valve 11 of the power water pipeline 10 is opened, and the metering pump 5 and the pipeline thereof are flushed.
The present invention is described by way of example with reference to the accompanying drawings, and it is to be understood that the invention is not limited to the specific embodiments described above. The present invention can be modified or modified by those skilled in the art without departing from the technical idea of the present invention, and such modifications or modifications naturally fall within the scope of the present invention.
