By arranging an electromagnetic flowmeter 1 on the chemical dosing equipment pipeline, the monitoring of the passing chemical dosing water flow can be realized, which can effectively avoid the leakage of the chemical dosing water pipe, resulting in poor water treatment effect, and can effectively avoid the waste of chemicals caused by the untimely discovery of problems by the staff. And by the electromagnetic flowmeter 1 composed of a double flowmeter combination, the overall monitoring effect on the chemical dosing pipeline 2 can be better, so that the water treatment effect of the water plant is good and the operation stability is high.

[0024] Among them, the electromagnetic flowmeter 1 is composed of a double flowmeter combination. A display is arranged on the front upper side of the electromagnetic flowmeter 1. A line connector is arranged on the upper side of the electromagnetic flowmeter 1. Flanges adapted to the flange adapter pipes 101 are correspondingly arranged on the chemical dosing pipeline 2. The flange adapter pipes 101 and the flanges on the chemical dosing pipeline 2 are connected by fixing bolts. A sealing gasket is arranged between the flange adapter pipes 101 and the flanges on the chemical dosing pipeline 2. Its function is that the external line can transmit the monitoring data of the electromagnetic flowmeter 1 on the chemical dosing pipeline 2 in real time through the line connector arranged on the electromagnetic flowmeter 1, so that the staff can clearly view the monitoring data of the electromagnetic flowmeter 1 and can find problems in time when problems occur, so that the operation detection stability of the water treatment in the water plant is good.

[0025] In this embodiment, refer to Figure 3 and 4As shown in the figure, the stop component 3 includes a stop valve pipe 301 installed on the chemical dosing pipeline 2. Inside the stop cavity of the stop valve pipe 301, stop baffles 302 are arranged corresponding to each other up and down. A sealing seat 303 is arranged at the left end of the stop valve pipe 301. A positioning and regulating seat 304 is arranged on the sealing seat 303. A regulating rod 305 is installed on the positioning and regulating seat 304. A regulating disc 306 is arranged at the outer end of the regulating rod 305. A stop head 307 is arranged at the inner end of the regulating rod 305. Through the pressure gauge 4, the internal pressure change of the chemical dosing pipeline 2 can be monitored.

Through the stop component 3, the partition between the chemical dosing pipeline 2 and the pressure gauge 4 can be realized, which can make the connection between the pressure gauge 4 and the chemical dosing pipeline 2 and the replacement of the pressure gauge 4 simple and convenient. Under the action of the stop component 3, the operation and use of the pressure gauge 4 are highly convenient. Under the action of the pressure gauge 4 and the electromagnetic flowmeter 1, a reminder can be sent in time when the inspection personnel do not conduct inspections in time, effectively reducing the waste of chemicals and improving the operation stability of the water treatment plant.

[0026] Among them, the pressure gauge 4 is arranged at the upper port of the stop valve pipe 301, and the pressure gauge 4 and the stop valve pipe 301 are connected by a mutually adapted threaded structure. Its function is that through the threaded connection between the pressure gauge 4 and the stop valve pipe 301, the connection and disassembly between the stop valve pipe 301 and the pressure gauge 4 are highly convenient.

Its function is that through the adaptation of the stop head 307 to the reserved cavity of the stop baffles 302, the stopping convenience of the stop component 3 is high and the use effect is good.

[0027] When the pipeline leakage device of the chemical dosing equipment is placed and used in this solution, the electromagnetic flowmeter 1 and the pressure gauge 4 are installed on the chemical dosing pipeline 2 to monitor the internal pressure of the chemical dosing pipeline 2 and the internal flow rate of the chemical dosing water pipe, so that the monitoring effect of the internal pressure and water flow rate of the chemical dosing pipeline 2 is good. When the pressure gauge 4 has problems, the control rod 305 is adjusted through the control panel 306, so that the stop head 307 is docked with the stop baffle 302 to realize the stop of the stop valve pipe 301, and the disconnection between the pressure gauge 4 and the chemical dosing pipeline 2 is realized to replace the pressure gauge 4. By setting the electromagnetic flowmeter 1 on the chemical dosing equipment pipeline, the monitoring of the passing chemical dosing water flow rate can be realized, which can effectively avoid the leakage of the chemical dosing water pipe, resulting in poor water treatment effect, and can effectively avoid the waste of chemicals caused by the untimely discovery of problems by the staff. And because the electromagnetic flowmeter 1 is composed of a double flowmeter combination, the overall monitoring effect of the chemical dosing pipeline 2 can be better, so that the water treatment effect of the water plant is good and the operation stability is high. Through the pressure gauge 4, the internal pressure change of the chemical dosing pipeline 2 can be monitored, and combined with the electromagnetic flowmeter 1, the monitoring comprehensiveness and safety of the chemical dosing pipeline 2 are high. Through the stop component 3, the disconnection between the chemical dosing pipeline 2 and the pressure gauge 4 can be realized, which can make the transfer between the pressure gauge 4 and the chemical dosing pipeline 2 and the replacement of the pressure gauge 4 simple and convenient. Under the action of the stop component 3, the operation and use of the pressure gauge 4 are highly convenient. Under the action of the pressure gauge 4 and the electromagnetic flowmeter 1, a reminder can be sent in time when the inspection personnel do not inspect in time, effectively reducing the waste of chemicals and improving the operation stability of the water treatment in the water plant.
