The concrete explanation is as follows:

1. and (3) water leakage alarm:

in the piping well of each unit, the system is provided with 3 water leakage detection probes.

1. If the first water leakage probe 11 detects the water leakage phenomenon, the system closes the first normally open electromagnetic valve 31, stops damage in time, sends out alarm information, informs maintenance personnel that the water leakage phenomenon exists at a position above the upper water tank, generates a timely work order, and requires the maintenance personnel to get to the site to repair and remove faults as soon as possible, and resumes water supply.

2. If the second water leakage probe 12 detects the water leakage phenomenon, the system closes the second normally open electromagnetic valve 32, stops damage in time, and sends out alarm information to inform maintenance personnel that the water leakage phenomenon exists at a position above the lower water tank, and a time work order is generated.

3. If the third water leakage probe 13 detects the water leakage phenomenon, the system closes the second normally open electromagnetic valve 32, stops damage in time, and sends out alarm information to inform maintenance personnel that the water leakage phenomenon exists at a position below the lower water tank, and a time work order is generated.

2. Other probe functions

1. The function of the pressure sensor:

if the pressure of the tap water is lower than 0.25Mpa or accumulated for 4 hours within 24 hours continuously and is lower than 0.25Mpa, a maintainer of the property should be warned to raise the secondary water supply pressure so that the pressure is changed between 0.25Mpa and 0.3 Mpa.

2. Action of water quality detection TDS probe:

action of the first TDS probe 15: the water quality of tap water is detected and only displayed to the user on the user APP.

Action of the second TDS probe 16: detecting the purity of the purified water, if the TDS value is larger than 5mg/L, informing maintenance personnel to replace the RO membrane to generate a periodic work order if the purified water does not meet the requirement.

Action of the third TDS probe 17: and detecting the mineral content of the direct drinking water, if the TDS value is not between 8 and 24mg/L, informing maintenance personnel to replace the mineralized filter element to generate a periodic work order if the mineral content of the direct drinking water does not meet the requirement.

3. Flow meter function:

1) The function of the first flowmeter 18 is to count the amount of tap water used per unit time in kilograms per day (kg/d) and to display the instantaneous flow rate of tap water in kilograms per hour (kg/h).

2) The effect of the second flowmeter 19 is to count the yield of purified water (drinking water) per unit time in kilograms per hour (kg/h).

3) The first flow meter 18/second flow meter 19 yields the total water purification rate. The RO membrane filter core should be replaced when the total water purification rate is not less than 35%, and a periodic work order is generated.

4) The maximum flow rate of the second flowmeter 19 when the system is operated for the first time is used as a default initial value, and when the upper tank water level is excessively low for more than 2 hours continuously:

4.1 If the flow rate of the second flowmeter 19 is greater than 70% of the initial value, when the upper tank water level is excessively low for 2 hours or more continuously: the alarm information should be that the system is not enough in power to generate a periodic work order.

4.2 If the flow of the second flowmeter 19 is less than 70% of the initial value, the alarm information should be that the system RO should be purged, and a periodic work order is generated.

4.3 If the flow of the second flowmeter 19 is 0), the alarm information should be that the system circuit part fails, and maintenance personnel should be notified to maintain in time, so as to generate a time work order.

4. Water level switch for upper water tank

1) Starting the water producing process

a. When the system is operated for the first time or the water tank 51 is completely anhydrous, the main control board 21 is electrified and is on line, the system starts water production, but 3 floating balls of the water level switch are in a falling state, and 3 floating balls are in a connection state, and the falling of the 3 rd floating ball triggers a low water level alarm signal, so that when the low water level alarm signal triggers, the system sets a delay time for 20 minutes and then alarms, and initial false alarm is prevented. The water level display is in the 1 state (the water level of the water tank is at the position below the lower ball).

b. When the water level in the upper water tank 51 rises gradually to float up to get off, the upper and middle floating balls of the water level switch are still in a falling on state, and the lower floating ball is in an off state, so that the low water level alarm signal disappears. The system continues to produce water. The water level display is in 2 state (the water level of the water tank is at the position above the lower ball and below the middle ball).

c. When the water level in the upper water tank 51 continues to rise to float the middle ball, the upper floating ball of the water level switch is still in a falling on state, and the middle and lower floating balls are in an off state. The system continues to produce water. The water level display is in 3 state (the water level of the water tank is above the middle ball and below the upper ball).

d. When the water level in the upper water tank 51 continues to rise to float up to get up the ball, the floating balls of the water level switch are all in an off state, and the system main control board relay K stops supplying power to the normally closed electromagnetic valve. At this time, the normally closed low-voltage switch arranged on the buffer pressure barrel pipeline 8 is in a connection state, and the normally closed low-voltage switch independently supplies power to the normally closed electromagnetic valve, so that the system continues to produce water. The water level display is in the 4 state (the water tank water level is in the ball-up position).

e. When the water pressure in the buffer pressure barrel rises to 0.011Mpa, the normally closed low-voltage switch is opened, and the system stops water production. The water level display is in the 4 state (the water level of the water tank is at the position above the upper ball float).

3. Water level drop process

1. The water level is 3 when the upper ball falls to connect the 9 and 10 feet of the float switch due to the water consumption of the user.

2. When the water level continues to drop and the middle ball falls to be connected with the 11 and 12 pins of the float switch, the main control board relay K is connected, water making is started, and the water level is displayed in a 2 state.

3. When the water level continues to drop and the falling ball is connected with the 13 and 14 pins of the float switch, the main control board relay K is still connected, water production is continued, and the water level is displayed in a 1 state. When the water level of the upper tank 51 is too low for more than 2 hours continuously, the system is ready to alarm: 3.1 if the flow of the second flowmeter 19 is greater than 70% of the initial value, the alarm message should be that the system is not enough in power, and a periodic work order is generated.

6. The water making process of the pipeline direct drinking water system comprises the following steps:

embodiments of the utility model are: step 1, sub-packaging tap water from a tap water meter in a top building, firstly, enabling tap water with pressure to sequentially pass through a pressure sensor of a tap water inlet mechanism 61, a normally closed electromagnetic valve and a first flowmeter 18, entering a pre-filtering mechanism (PP cotton+activated carbon+PP cotton) hung in a water meter well of the top building to perform primary filtering to obtain primary filtered water without bleaching powder and sediment impurities (the pressure consumed by the pre-filtering mechanism is about 0.1 Mpa), downwards placing the primary filtered water into an 8-layer building through a No. 1 pipe to increase the primary filtered water pressure by 0.24Mpa, enabling the pressure before passing through a primary filtered water film of an RO film to meet the requirement of 0.5+/-0.05 Mpa, and enabling a machine room for secondary water supply to properly raise the tap water pressure of the top building to be between 0.25Mpa (0.25-0.3 Mpa) if the tap water pressure of the top building is lower than 0.25 Mpa.

After passing through the RO reverse osmosis membrane, the primary filtered water is separated into purified water and wastewater, the wastewater is discharged into nearby sewer, the primary filtered water passes through the RO reverse osmosis membrane to obtain purified water, the purified water passes through the second flowmeter 19, and then passes through the mineralized filter element to obtain mineral substances, so that direct drinking water is obtained, the consumption pressure is 0.1+/-0.01 Mpa, and the whole filtration process consumes the pressure is 0.2+/-0.02 Mpa.

The tap water inlet mechanism 61 consists of a pressure display meter, a TDS on-line detection probe, a pressure sensor and a normally closed electromagnetic valve, wherein the pressure display meter is only used for displaying tap water pressure, and does not have functional effect on the whole filtering process.

1. The primary filtered water passes through the RO reverse osmosis membrane to obtain purified water, the wastewater from the RO reverse osmosis membrane is discharged into a sewer nearby, and the primary filtered water enters the pure water mechanism 62 and the mineralization mechanism 63 to obtain the direct drinking mineral water.

2. A first flowmeter 18 is installed at the end of the tap water inlet mechanism 61, and a second flowmeter 19 is installed at the purified water outlet end of the purified water mechanism 62 for calculating the purified water rate, q=q2/q1x100%. If the system detects that the Q value is less than 35%, the system should alarm to generate a periodic work order, and the RO membrane filter core is replaced.

7. And (3) a water storage process:

1. after the direct drinking water flows out through the mineralizing mechanism 63, the direct drinking water is converted into a No. 7 pipe through a No. 2 pipe and is stored in the lower water tank 52 nearby preferentially due to the pressure difference.

2. After the water in the lower water tank 52 is full, the upper float valve in the lower water tank 52 is closed, the direct drinking water continues to be stored in the upper water tank 51 upwards through the No. 2 pipe, when the upper water tank 51 is full, the upper ball of the upper float switch in the upper water tank 51 floats, the 9-10 contacts are disconnected, and the main control board 21 disconnects the relay K. The normally closed pressure switch 42 continues to supply power to the normally closed water inlet solenoid valve and the system continues to produce water so that the water level of the upper tank 51 continues to rise until such time as the upper float valve of the upper tank 51 floats and closes. The direct drinking water enters the top-layer user home micro buffer water tank 53 from the No. 2 pipe to the No. 9 pipe through the No. 8 pipe, and after the top-layer user home micro buffer water tank 53 is full of water and the floating ball valve is closed for water inflow, the direct drinking water finally enters the buffer pressure barrel until the water storage pressure in the buffer pressure barrel 43 rises to exceed 0.011Mpa, the normally closed pressure switch 42 is powered off, the tap water inflow electromagnetic valve is closed, and water production is stopped.

3. The upper float switch in the upper water tank 51 is installed at a height such that the water level required for floating the upper ball is lower than the water level required for closing the upper float valve, so that the upper ball of the float switch is ensured to be indeed floated when the upper float floats to disconnect the circuit, and the main control board relay K stops working.

4. The water storage process is as follows in sequence no matter what conditions are used for starting the water production: the lower water tank 52, the upper water tank 51, the top-level user home micro buffer water tank 53, and finally enter the buffer pressure tank 43.

8. Starting the conditions and the process of water production:

1. when the system is started for the first time or no water exists in the buffer pressure barrel 43 and the upper water tank 51, the normally closed pressure switch 42 and the main control board relay K are connected for 2 and 3 points to supply power to the normally closed water inlet electromagnetic valve at the same time, and water making is started.

2. After the system is started for the first time and put into formal operation, when a user uses the water in the upper water tank 51 to descend by using the middle ball of the upper floating ball switch, the 11 and 12 points of the upper floating ball in the upper water tank 51 are connected, the 2 and 3 points of the main control board relay K are connected, and water production is started.

3. After the system is started for the first time and put into normal operation, if only the lower water tank 52 lacks water, even if a user supplied by the upper water tank 51 does not use water, the water level of the upper water tank 51 is in a full water state, the lower ball of the float switch cannot descend to start the relay K of the main control board to enable 2 and 3 points to be connected for water production, and when the buffer pressure barrel 43 is full of water, but when the user supplied by the lower water tank 52 uses the water in the lower water tank 52 to the position below the middle float valve of the lower water tank 52, and the middle float valve is automatically opened, the water in the upper water tank 51 flows into the lower water tank 52 through the water pipes of No. 4 and No. 6 in sequence, and as the water level of the upper water tank 51 descends, the middle ball 11 and 12 points of the float switch in the upper water tank 51 are connected, and the relay K of the main control board is connected at 2 and 3 points to start the normally closed electromagnetic valve for water production.

4. After the system is started for the first time and put into formal operation, if only direct drinking water in the buffer pressure barrel of the top building is supplied with water to cause the pressure to be less than 0.004Mpa, the normally closed pressure switch is switched on, the system supplies power to the normally closed water inlet electromagnetic valve, and water production is started. When the water pressure in the buffer pressure barrel exceeds 0.011Mpa, the pressure switch is powered off, and the water inlet electromagnetic valve is closed to stop water production.

At this time, if the pressure in the buffer pressure barrel 43 is greater than 0.011Mpa, the pressure switch is in an off state, and the power adapter stops supplying power to the normally closed solenoid valve, stopping water production.

At this time, if the pressure in the buffer pressure barrel is less than 0.004Mpa, the normally-closed low-voltage switch is turned on, and the power supply is adapted to directly supply power to the normally-closed electromagnetic valve, so as to continuously produce water.

That is, the normally closed water inlet solenoid valve is controlled by two parallel independent switches, one is a pressure switch and the other is a relay K controlled by the main control board 21. The pressure switch is controlled by the buffer pressure barrel 43, and the relay K of the main control board 21 is controlled by the float switch.

Further, the pressure sensor 14 is controlled by tap water, and the relay K controlled by the main control board 21 can be turned on at points 2 and 3 only when water is detected. The normally closed electromagnetic valve can be opened to produce water.

As can be seen from the flowchart of fig. 9, the conditions for starting water production are: the pressure sensor 14 must detect tap water, and inform the main control board 21 to switch on the relay K, so that the 2 and 3 points are switched on, and at least one of the normally closed pressure switch and the main control board relay K is switched on.

The conditions for stopping water production are as follows: the normally closed pressure switch and the main control board relay K are simultaneously turned off or the pressure sensor 14 detects that tap water is not in the tap water inlet mechanism 61.

Further, when a cell is provided with a non-water-making unit, the conditions for starting the system to make water are as follows:

4. Furthermore, through No. 2 pipeline, direct drinking water can be provided for the unit attic without water production equipment through the basement. If the floor is less than 20 floors, the lower water tank can be omitted, water can be supplied from the No. 4 pipe of the upper water tank 51 to the floor 1, and if the water supply pressure needs to be reduced due to the too high floor, the pressure reducing valve is installed at the proper position of the No. 4 pipe in a gradient manner to reduce the pressure.

1) Further, if the floor of the unit without water producing equipment is the same as the water producing unit, only the upper water tank 51 is required.

2) Further, the step-installation of the pressure reducing valve means that if the water supply floor of the buffer water tank 51 or 52 in the piping shaft exceeds more than ten floors, a constant pressure reducing valve should be provided every not more than ten floors so that the pressure of the direct drinking water entering the user's home is not more than 0.35Mpa.
