Detailed Description

The utility model will be described in detail below with reference to the drawings in connection with embodiments. It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. For convenience of description, the words "upper", "lower", "left" and "right" are used hereinafter to denote only the directions corresponding to the upper, lower, left, and right directions of the drawings, and do not limit the structure.

As shown in fig. 1, the pipeline direct drinking water system provided in this embodiment includes a tap water inlet mechanism 100, an upper water tank 200, a lower water tank 300, a first filtering mechanism 400, a second filtering mechanism 500, a buffer pressure water supply mechanism 600, an indoor water tank 700, an upper ball valve 800, a float switch 900, a relay 110, an ozone sterilization tank 111, a direct drinking water meter 113 for entering a household, a first ball valve 114, a second ball valve 115, and a power adapter 116.

The tap water inlet mechanism 100 is provided with a tap water meter 101, a pressure gauge 102, a low-voltage switch 103 and a normally closed electromagnetic valve 104.

The first filter mechanism 400 includes first PP cotton 401, second PP cotton 403, and activated carbon 402.

The second filtration mechanism 500 includes a first RO membrane 501, a second RO membrane 502, a mineralized cartridge 503, and a third PP cotton 504.

The buffer pressure water supply mechanism 600 includes a check valve 601, a normally closed pressure switch 602, and a buffer pressure tub 603.

The indoor water tank 700 comprises a horizontal pipe 701, a vertical pipe 702 and a direct drinking tap 703. An upper ball 901 and a lower ball 902 are arranged in the float switch 900, and the upper ball 901 and the lower ball 902 are normally closed float switches.

The upper water tank 200 is arranged on a top floor, an upper ball float valve 800 is arranged in the upper water tank 200, the upper ball float valve 800 works independently, and the ball float switch 900 is electrically connected with the relay 110. An upper ball float valve 800 and a middle ball float valve 112 are arranged in the lower water tank 300.

The power adapter 116, the relay 110 and the normally closed electromagnetic valve 104 all adopt DC24V; the withstand voltage values of the float switch 900 and the normally closed pressure switch 602 are 100V.

As shown in fig. 1 and 2, the working principle of the relay 110 is as follows: the negative pole line of the power adapter 116 is connected to the pin J13 of the working coil of the relay 110, and the negative pole line of the normally closed solenoid valve 104 is also connected to the pin J13 of the working coil of the relay 110, thereby forming a loop of power supply. When the upper ball 901 of the float switch 900 floats, the lower ball 902 also floats, the relay 110 does not operate, and the positive power supply of the power adapter 116 cannot supply power to the J6 pin of the relay 110 through the J10 pin of the relay 110, so that the normally closed electromagnetic valve 104 has no operating current. When the upper ball 901 of the float switch 900 falls, the pins F15 and F16 of the float switch 900 are turned on, and the current still cannot supply power to the pin J9 after reaching the pin J5 of the relay 110, so that the coil of the relay 100 still cannot be turned on.

Only when the water surface of the upper water tank 200 continues to descend, the lower ball 902 falls, and when the pins F17 and F18 of the float switch 900 are connected, the positive current of the power adapter 116 reaches the pin J9 of the relay 110 sequentially through the pins F16, F15, F17 and F18 of the float switch 900, the pin J9 and the pin J14 of the relay 110 are communicated, so that the positive electrode and the negative electrode of the coil of the relay 110 are connected with the positive electrode and the negative electrode of the power adapter 116, the relay 110 works, the pin J5 and the pin J9 of the relay 110 are conducted to realize the self-locking function of the relay, and the pin J6 and the pin J10 are conducted.

As a result of the conduction between the J5 pin and the J9 pin, the electricity of the coil of the relay 110 does not need to pass through the J16, the J15, the J17, the J18 and the J9 pin to reach the J14 pin of the coil, but passes through the F16 and the F15 of the float switch and the J5 and the J9 pin of the relay to reach the J14 pin of the coil, and even if the water surface rises after the water preparation is started, the lower ball 902 floats upwards and is disconnected, the relay 110 can still work continuously to prepare water continuously. The operating power of relay 110 is not turned off until ball 901 of float switch 900 floats. At this time, if the pressure in the buffer pressure tank 600 is greater than 0.01Mpa, the normally closed pressure switch 602 is in an off state, and the power adapter 116 stops supplying power to the normally closed solenoid valve 104, stopping water production.

At this time, if the pressure in the buffer pressure tank 600 is less than 0.01Mpa, the power adapter 116 continues to supply power to the normally closed solenoid valve 104 through the normally closed pressure switch 602 in the on state, although it does not supply power to the normally closed solenoid valve 104 through the relay 110, and continues to make water.

Thus, the control normally closed solenoid 104 has two parallel, independent switches, one normally closed pressure switch 602 and the other relay 110. Normally closed pressure switch 602 is controlled by the buffer pressure barrel and relay 110 is controlled by float switch 900.

The low-voltage switch 103 is controlled by tap water pressure, is turned on by water, is turned off by no water, and can be turned on by the normally-closed electromagnetic valve 104 only when tap water is present, so that water production can be started.

And a No. 6 pipe is communicated with a No. 8 pipe between the check valve 601 and the normally closed pressure switch 602, and the No. 6 pipe is communicated with an indoor water tank 700 of an attic.

The pipeline direct drinking water system provided by the utility model utilizes the pressure difference between different floors of the pressure superposition of more than ten layers of secondary water supply of high-rise tap water, and the sum of the two pressures forms the pressure required by the first filtering mechanism 400 and the second filtering mechanism 500 to prepare direct drinking water. And the booster pump equipment of the traditional pipeline direct drinking water system is canceled.

The one-way valve 601 aims to prevent direct drinking water entering the buffer pressure barrel 603 from flowing back to the No. 2 pipe, so that the direct drinking water in the buffer pressure barrel 603 is specially used for top users through the No. 8 pipe to the No. 6 pipe.

The normally closed pressure switch 602 is turned off at a pressure of 0.01Mpa, which is a key component of the buffer pressure water supply mechanism 600 that operates independently, and when the direct drinking water pressure in the buffer pressure barrel 603 reaches 0.01Mpa, the normally closed pressure switch 602 is turned off to stop water production. And a pressure of 0.01Mpa is sufficient to allow the direct drinking water in the present buffer pressure barrel 603 to flow into the indoor water tank 700 (micro water tank) in the user's home.

An indoor water tank 700 is independently arranged on each kitchen suspended ceiling of the user's home, the height is 20cm, the length is multiplied by the width=25cm×25m, the flow and the pressure of the direct drinking water faucet 703 of each user's home are consistent, and the direct drinking water faucet is not influenced by the pressure and the flow in a direct drinking water pipeline in a pipeline well in a water use peak period.

The water storage amount of the indoor water tank 700 is controlled to be 3.5-4L, which is smaller than the daily water consumption (average 6L/user) of the user, and the water is continuously replenished and updated every day, so that the freshness of the water quality is ensured. The indoor water tank 700 is combined with the upper water tank, the lower water tank and the buffer pressure barrel 603 in the pipeline well to form a complete buffer water supply system, so that the device is suitable for the characteristic that the number of users in a community is continuously increased, and the purpose of elastic water supply is realized.

The indoor water tank 700 should be provided with a water outlet formed by integral injection molding with the tank body at the bottom, and the slope of about 5 degrees should be formed between the periphery of the tank bottom and the water outlet, so that the water can be thoroughly discharged when a user cleans the water tank. An upper ball float valve 800 is arranged in the indoor water tank 700.

If the user goes out for more than 3 days, the second ball valve 115 is closed, the direct drinking tap 703 is opened, and the direct drinking water in the indoor water tank 700 is discharged. When the user returns outside, the second ball valve 115 and the direct drinking tap 703 are opened to drain water for 3 minutes, and the direct drinking water in the pipeline between the pipeline well and the indoor water tank 700 is updated, and then the user can drink the water.

The upper water tank and the lower water tank in the pipeline well are respectively provided with an independent ozone sterilization box 111, sterilization and fresh-keeping are carried out at 1 point every night for 40 minutes, natural volatilization of ozone only needs more than 30 minutes after sterilization, and the owners are relieved to use after 5 points.

The ozone sterilization box 111 is composed of a transformer, a blower, an ozone generating tube, a timer, an ozone output tube and a dispersing balloon extending into the bottom of the water tank.

The utility model provides an implementation step of the pipeline direct drinking water system, which comprises the following steps:

step 1, an installation step:

step 1.1, the running water meter 101 is split-packed in the top building to obtain the running water.

Step 1.2, tap water with pressure is fed into a first filtering mechanism 400 (PP cotton + activated carbon + PP cotton) hung in a top water meter well through a low-voltage switch 103 and a normally-closed electromagnetic valve 104 of a tap water feeding mechanism 100 in sequence for primary filtering, so as to obtain primary filtered water without bleaching powder and sediment impurities, and the original pressure of tap water consumed by the first filtering mechanism 400 is about 0.1Mpa.

And 1.3, the primary filtered water is downwards placed on 8-10 floors through a No. 1 pipe, so that the primary filtered water pressure is increased by 0.24-0.3Mpa, the number of floors to be placed is determined according to the pressure of the primary filtered water, the principle that the pressure before the primary filtered water passes through an RO membrane meets the requirement of 0.5-0.7Mpa is adopted, and if the top building tap water pressure is lower than 0.25Mpa, a machine room for secondary water supply can be required to properly regulate the top building tap water pressure to be higher than 0.25Mpa.

And 1.4, separating the primary filtered water into purified water and wastewater after passing through the RO reverse osmosis membrane, and discharging the wastewater into nearby sewer. Purified water is mineralized by a mineralizing filter element 503 to obtain mineral substances, and tiny mineral particles are filtered by a third PP cotton 504 to obtain clean direct drinking water, wherein the consumption pressure is about 0.1Mpa, and the consumption pressure in the whole filtering process is about 0.2Mpa.

The tap water inlet mechanism 100 comprises a tap water meter 101, a pressure meter 102, a low-voltage switch 103 and a normally-closed electromagnetic valve 104, wherein the pressure meter 102 is only used for displaying the tap water pressure and does not have a functional effect on the whole filtering process.

The primary filtered water passes through an RO reverse osmosis membrane to obtain purified water, and passes through a first RO membrane 501 and a second RO membrane 502 which are connected end to end. The primary filtered water firstly enters the first RO membrane 501, the wastewater from the first RO membrane 501 enters the RO reverse osmosis membrane 2 for filtering again, the wastewater from the second RO membrane 502 is discharged into the sewer nearby, and the purified water from the two RO reverse osmosis membranes is merged and sent into the mineralized filter element 503 and the third PP cotton to obtain the direct drinking mineral water.

The first RO membrane 501 and the second RO membrane 502 adopt a filtration mode of end-to-end connection, which is used for improving the water purifying rate of the system, and compared with a traditional single-membrane filtration mode, the filtration mode of end-to-end connection of double membranes is used for improving the water purifying rate of the system by almost 1 time. The water purification rate is improved from 35% of the single-membrane filtration mode to 65% of the double-membrane end-to-end filtration mode, and water resources are greatly saved.

Step 2, a water storage method:

in step 2.1, the direct drinking water generated in step 1.4 flows out from the third PP cotton 504 into the No. 2 pipe, and is preferably stored in the lower water tank 300 from the No. 2 pipe to the No. 7 pipe due to the pressure difference.

Step 2.2, after the lower tank 300 is full of water, the upper ball float valve 800 in the lower tank 300 is closed, and the direct drinking water continues to be stored upwards into the upper tank 200 through the pipe No. 2.

And 2.3, when the upper ball of the float switch 900 in the upper water tank 200 floats upwards due to the water filling of the upper water tank 200, the normally closed relay 110 is disconnected, the relay 110 stops working, and the normally closed pressure switch 602 continues to supply power to the normally closed electromagnetic valve 104 of the tap water inlet mechanism 100. The tap water inlet mechanism 100 continues to supply water, so that the water surface of the upper water tank 200 continues to rise, and the direct drinking water enters the indoor water tank 700 at the top layer from the pipe No. 2 through the pipe No. 8 and then through the pipe No. 6 until the upper floating ball valve 800 of the upper water tank 200 floats to be closed.

And 2.4, when the indoor water tank 700 at the top layer is full, the upper float valve 800 is closed to feed water, direct drinking water enters the buffer pressure barrel 603 of the buffer pressure water supply mechanism 600 through the one-way valve, until the water storage pressure in the buffer pressure barrel 603 rises to 0.01Mpa, the normally closed pressure switch 602 is powered off, the tap water feed mechanism 100 is closed, and water production is stopped.

The installation height of the float switch 900 in the upper water tank 200 should be such that the water level required when the upper ball 901 floats is lower than the water level when the upper ball valve 800 is closed, so as to ensure that the upper ball 901 of the float switch 900 does float when the float 800 in the upper water tank 200 is closed, so that the relay 110 stops working.

The water storage sequence of the water preparation is as follows in sequence no matter what conditions are, namely: lower tank 300, upper tank 200, top-level user's home tank 700, buffer pressure tank 603.

Conditions and processes for starting and stopping the production of water:

if the system is started for the first time or no water exists in the buffer pressure barrel 603 and the upper water tank 200, the normally closed pressure switch 602 and the relay 110 supply power to the normally closed electromagnetic valve 104 at the same time, and water making is started.

After the system is started for the first time and put into normal operation, when a user uses water in the upper water tank 200 to lower the lower ball 902 of the floating ball switch 900, the relay is switched on and is normally open, and the relay is started to start water production.

After the system is started for the first time and put into normal operation, if only the lower water tank 300 lacks water, the water level of the upper water tank 200 is in a full water state, and the lower ball 902 of the float switch 900 cannot descend to start the relay 110 to produce water. At this time, the buffer pressure tank 603 is also full of water, but the user supplied by the lower tank 300 uses the water in the lower tank 300 to a position below the middle ball float valve 112 of the lower tank 300, when the middle ball float valve 112 is automatically opened, the direct drinking water in the upper tank 200 flows into the lower tank 300 from the pipe No. 4 to the pipe No. 3 in sequence, and as the water level of the upper tank 200 drops, the lower ball 902 of the float switch 900 in the upper tank 200 is connected to the normally open relay 110, and water making is started.

After the system is started for the first time and put into normal operation, if only direct drinking water in the buffer pressure barrel 603 of the top building is supplied with water to cause the pressure to be less than 0.01Mpa, the normally closed pressure switch 602 is turned on, the system supplies power to the normally closed electromagnetic valve 104, and water production is started.

When the water pressure in the buffer pressure barrel 603 exceeds 0.01Mpa, the normally closed pressure switch 602 is turned off, and when the solenoid valve is closed in a water full state in the upper water tank, or when tap water is stopped, the normally closed solenoid valve 104 stops water production.
