[0021] The multi-point quantitative constant speed water intake system includes a water intake system pipeline 10 connected to a water source, wherein the water intake system pipeline 10 includes a variable frequency circulation pump 4, a UV sterilizing lamp 5, a plurality of fine purification columns, a circulation pressure sensor 8, a first electromagnetic switch valve 11, a water inlet 1 and a wastewater outlet 2, such as Figure 1 As shown, the polishing column includes a first polishing column 6 and a second polishing column 7 .

[0022] The variable frequency circulation pump 4, UV sterilization lamp 5, several refining columns, circulation pressure sensor 8, and electromagnetic switch valve are connected through a pipeline 10. The water inlet 1 is connected to a water tank. Several water intake arm assemblies 12 for precise quantitative water intake and constant speed water intake are installed on the pipeline 10 at the output end of the first electromagnetic switch valve 11. An electromagnetic reversing valve 13 is provided on the wastewater outlet 2, and a second electromagnetic switch valve 14 is provided on the pipeline 10 at the output end of the water intake arm assembly 12.

[0023] It also includes a TOC water quality detector 9, which is electrically connected to the first electromagnetic switch valve 11. One end of the TOC water quality detector 9 is arranged on the pipeline 10 before the input end of the first electromagnetic switch valve 11, and the other end of the TOC water quality detector 9 is arranged on the electromagnetic reversing valve 13.

[0024] The variable frequency circulation pump 4 adopts a UP circulation pump, which is used to keep the water pressure in the pipeline 10 constant. The fine purification column is used to remove ions in the water and also includes a dosing pipe 3, which is arranged on the pipeline 10 between the water inlet 1 and the variable frequency circulation pump 4.

[0025] The water intake arm assembly 12 includes symmetrically arranged three-way pipes 1201, a pressure-stabilizing valve 1202 arranged on one of the three-way pipes 1201, a normally closed valve 1203, a flow meter 1204, a terminal water quality detector 1205 and an adjustable proportional needle valve 1206. The other end of the adjustable proportional needle valve 1206 is connected to an internal circulation diaphragm pump 1208, and the internal circulation diaphragm pump 1208 is connected to another three-way pipe 1201. The two three-way pipes 1201 are unidirectionally connected, and the remaining connecting ports of the two three-way pipes 1201 are connected to the pipeline 10. The output end of the adjustable proportional needle valve 1206 is provided with an arm outlet 1207, and the arm outlet 1207 is used for water outlet.

[0026] Specific implementation process:

[0027] The water inlet 1 is connected to a water tank or a water source. At this time, the electromagnetic reversing valve 13 is in a closed state. The water purification agent is added to the dosing pipe 3, and then the flowing water enters the variable frequency circulation pump 4, the UV sterilizing lamp 5, and several fine purification columns to purify the water. At this time, the first electromagnetic switch valve 11 is in a closed state, and then the water flow is detected by the TOC water quality detector 9. If the water quality does not meet the standard, the water flow is circulated. If it meets the standard, the controller is used to transmit the standard signal detected by the TOC water quality detector 9 to the first electromagnetic switch valve 11, and the first electromagnetic switch valve 11 is opened;

[0028] At this time, the water flows to the first electromagnetic switch valve 11, and enters the water intake arm assembly 12 through the first electromagnetic switch valve 11.

[0029] Regarding the water flow entering the water intake arm assembly 12: the diameter of the three-way pipe 1201 is smaller than the diameter of the pipeline 10, ensuring that each water intake arm assembly 12 can take in water, and then the water flows into the three-way pipe 1201, and a pressure-stabilizing valve 1202 is arranged inside to buffer the pressure drastic change. The flow meter 1204 is used as a feedback signal of the quantitative water intake function. This feedback signal is used to open the normally closed valve 1203. The opening size of the normally closed valve 1203 is used to achieve quantitative water intake. After the quantitative water intake, the water flow enters the adjustable proportional needle valve 1206. The adjustable proportional needle valve 1206 is a needle valve. The needle valve can control the size of the control outlet, and then the adjustable proportional needle valve 1206 is used to achieve constant speed water intake. Figure 2 As shown, the water intake arm assembly 12 is also provided with an internal circulation diaphragm pump 1208 , which can be used to force the circulation of dead water in the water intake arm assembly 12 .

[0030] Finally, the outlet position of the electromagnetic reversing valve 13 is changed and the second electromagnetic valve is opened, so that the water can flow into the wastewater outlet 2.

[0031] The device solves the technical difficulties of the traditional water intake system in accurately taking water in a fixed quantity and taking water at a fixed speed.
