The current pipeline direct drinking water system generally needs to set a dedicated water purification room, which has the following defects:

Detailed Implementation

[0046] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" used below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0047] like Figure 1 As shown, the piped 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 filtration mechanism 400, a second filtration mechanism 500, a buffer pressure water supply mechanism 600, an indoor water tank 700, a float ball valve 800, a float switch 900, a relay 110, an ozone sterilization box 111, an inlet direct drinking water meter 113, a first ball valve 114, a second ball valve 115, and a power adapter 116.

[0048] The tap water inlet mechanism 100 is equipped with a tap water meter 101, a pressure gauge 102, a low-pressure switch 103, and a normally closed solenoid valve 104.

[0049] The first filtration mechanism 400 includes a first PP cotton 401, a second PP cotton 403, and activated carbon 402.

[0050] The second filtering mechanism 500 comprises a first RO membrane 501, a second RO membrane 502, a mineralization filter element 503 and a third PP cotton 504.

[0051] The buffer pressure water supply mechanism 600 comprises a one-way valve 601, a normally closed pressure switch 602 and a buffer pressure tank 603.

[0052] The indoor water tank 700 comprises a horizontal pipe 701, a vertical pipe 702 and a direct drinking water faucet 703. The float ball switch 900 is internally provided with an upper ball 901 and a lower ball 902, both of which are normally closed float ball switches.

[0053] The upper water tank 200 is arranged on the top floor, and the upper water tank 200 is internally provided with an upper float ball valve 800, which works independently, and the float ball switch 900 and the relay 110 are electrically connected. The lower water tank 300 is internally provided with an upper float ball valve 800 and a middle float ball valve 112.

[0054] The power adapter 116, the relay 110 and the normally closed electromagnetic valve 104 all adopt DC 24V; the withstand voltage values of the float ball switch 900 and the normally closed pressure switch 602 are both 100V.

[0055] As shown in Figure 1 , Figure 2 The working principle of the relay 110 is as follows: the negative pole line of the power adapter 116 is connected with the working coil J13 pin of the relay 110, and the negative pole line of the normally closed electromagnetic valve 104 is also connected with the working coil J13 pin of the relay 110, thereby forming a power supply loop. When the upper ball 901 of the float ball switch 900 floats up, the lower ball 902 also floats up, the relay 110 does not work, the positive pole 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, and the normally closed electromagnetic valve 104 has no working current. When the upper ball 901 of the float ball switch 900 falls down and the F15 and F16 pins of the float ball switch 900 are connected, the current reaching the J5 pin of the relay 110 still cannot supply power to the J9 pin, and the coil of the relay 100 still cannot be turned on.

[0056] Only when the water surface of the upper water tank 200 continues to fall down, the lower ball 902 falls down and the F17 and F18 pins of the float ball switch 900 are connected, the positive pole current of the power adapter 116 reaches the J9 pin of the relay 110 through the F16, F15, F17 and F18 pins of the float ball switch 900 in sequence, the J9 pin and the J14 pin of the relay 110 are connected, the positive and negative poles of the coil of the relay 110 are connected with the positive and negative poles of the power adapter 116, the relay 110 works, the J5 pin and the J9 pin of the relay 110 are connected to realize the self-locking function of the relay, and the J6 pin and the J10 pin are connected.

[0057] The result of the conduction between J5 and J9 is that the electricity of the relay 110 coil no longer needs to pass through J16, J15, J17, J18, J9 to the J14 of the coil in turn, but passes through F16, F15 of the float switch, J5 and J9 of the relay to the J14 of the coil in turn. Even if the water surface rises after starting to make water and causes the lower ball 902 to float and disconnect, the relay 110 can still work and continue to make water. Until the upper ball 901 of the float switch 900 floats, the power supply of the relay 110 is cut off. At this time, if the pressure in the buffer pressure tank 600 is greater than 0.01 Mpa, the normally closed pressure switch 602 is in the disconnected state, and the power adapter 116 stops supplying power to the normally closed electromagnetic valve 104, and stops making water.

[0058] At this time, if the pressure in the buffer pressure tank 600 is less than 0.01 Mpa, the power adapter 116 continues to supply power to the normally closed electromagnetic valve 104 through the normally closed pressure switch 602 in the connected state, and continues to make water, although it does not supply power to the normally closed electromagnetic valve 104 through the relay 110.

[0059] Therefore, there are two parallel and independent switches for controlling the normally closed electromagnetic valve 104, one is the normally closed pressure switch 602, and the other is the relay 110. The normally closed pressure switch 602 is controlled by the buffer pressure tank, and the relay 110 is controlled by the float switch 900.

[0060] The low-voltage switch 103 is controlled by the water pressure of the tap water, and is connected when there is water and disconnected when there is no water. Only in the case of tap water, the normally closed electromagnetic valve 104 can be connected, and the water making can be started. The first PP cotton 401, the activated carbon 402 and the second PP cotton 403 are connected in turn. The first PP cotton 401 is communicated with the outlet of the tap water inlet mechanism 100, and the second PP cotton 403 is communicated with the water inlet of the first RO membrane 501 of the second filtering mechanism 500 through a No. 1 pipe.

[0061] The pure water outlet of the first RO membrane 501 and the pure water outlet of the second RO membrane are combined and communicated with the mineralization filter element 503, and the waste water outlet of the first RO membrane 501 is connected with the water inlet of the second RO membrane 502. The waste water outlet of the second RO membrane 502 is communicated with the nearest sewer through a waste water ratio, which is a fixed flow limiting valve. The mineralization filter element 503 is communicated with the third PP cotton 504, and the outlet of the third PP cotton 504 is communicated with No. 7 pipe and No. 8 pipe through No. 2 pipe, the top end of No. 2 pipe is communicated with the upper float valve 800 of the upper water tank 200, and the upper float valve 800 of the lower water tank 300 is communicated with No. 7 pipe.

[0062] The one-way valve 601, the normally closed pressure switch 602 and the buffer pressure tank 603 are sequentially communicated on the 8# pipe. The 6# pipe is communicated between the one-way valve 601 and the normally closed pressure switch 602, and the 6# pipe is communicated with the indoor water tank 700 on the top floor.

[0063] The indoor water tank 700 is arranged in each floor and each house. In the embodiment, the indoor water tank 700 is installed in the kitchen ceiling of the user's home. The first ball valve 114, the indoor direct drinking water meter 113 and the second ball valve 115 are sequentially communicated on the direct drinking water pipe of the indoor water tank 700 of each house. The second ball valve 115 is located between the indoor direct drinking water meter 113 and the indoor water tank 700.

[0064] The bottom of the indoor water tank 700 is provided with a horizontal pipe 701 and a vertical pipe 702 communicated with the horizontal pipe 701, the end of the vertical pipe 702 is a direct drinking water faucet 703, and the corner of the horizontal pipe 701 and the vertical pipe 702 is provided with an emptying device. The top of the indoor water tank 700 is provided with an emptying hole, and the emptying device and the emptying hole are both provided with an air filter screen to prevent dust from entering.

[0065] The indoor water tank 700 is arranged in each floor and each house, the lower water tank 300 is communicated with the indoor water tank 700 of the first floor to the middle floor through the 5# pipe. The upper water tank 200 is communicated with the indoor water tank of the middle floor to the lower floor of the top floor through the 4# pipe. The upper water tank 200 is communicated with the middle floating ball valve 112 of the lower water tank 300 through the 4# pipe to the 3# pipe. The buffer pressure water supply mechanism is communicated with the indoor water tank on the top floor.

[0066] In a specific embodiment, the pipeline direct drinking water system is applied to a building with 25 floors, the lower water tank 300 is communicated with the indoor water tank 700 of the first floor to the thirteenth floor through the 5# pipe. The upper water tank 200 is communicated with the indoor water tank 700 of the fourteenth floor to the twenty-fourth floor through the 4# pipe. The buffer pressure tank is communicated with the indoor water tank 700 on the top floor through the 8# pipe to the 6# pipe.

[0067] The functions of each filter element are as follows:

[0068] The first PP cotton 401 is used for filtering the silt impurities in tap water;

[0069] The activated carbon 402 is used for filtering the bleaching powder in tap water;

[0070] The second PP cotton 403 is used for filtering the small activated carbon particles flowing out of the activated carbon filter element, and protecting the RO reverse osmosis membrane behind;

[0071] The first RO membrane 501 is used for filtering the primary filtered water filtered by the first filtering mechanism 400, preparing the first-stage pure water, and sending the waste water to the second RO membrane 502 for re-filtering;

[0072] Second RO membrane 502: for filtering the waste water filtered by the first RO membrane 501 again, and discharging the waste water to the sewer nearby by controlling the flow of the waste water.

[0073] Mineralization filter core: for obtaining mineral water by reducing and supplementing various minerals required for human health through the mineralization filter core.

[0074] Third PP cotton: for filtering out the mineral residue in the mineralization process.

[0075] The pipeline direct drinking water system provided by the application cancels the special water purification machine room construction of the traditional pipeline direct drinking water system, uses the water pipe well of a high-rise building to replace the traditional water purification machine room, and disperses all water purification equipment on the walls of the water pipe well of different floors, thereby saving the land occupation and construction cost of the water purification machine room.

[0076] The pipeline direct drinking water system provided by the application uses the pressure superposition of the secondary water supply of the water of a high-rise building with more than ten floors and the pressure difference between different floors, and the sum of the two parts of pressure constitutes the pressure required by the first filtering mechanism 400 and the second filtering mechanism 500 to prepare direct drinking water. The pipeline direct drinking water system cancels the booster pump equipment of the traditional pipeline direct drinking water system.

[0077] The buffer pressure water supply mechanism 600 is arranged at the top floor, and is composed of a one-way valve 601, a normally closed pressure switch 602 with a disconnection pressure of 0.01 Mpa and a buffer pressure barrel 603, can automatically control the subsystem of water preparation and water supply to the users of the floor, is specially used for the users of the top floor, overcomes the difficulty of insufficient water supply pressure of the water tank of the top floor to the users of the same floor, and realizes the target of the water supply without dead angle of the application.

[0078] The one-way valve 601 aims to prevent the direct drinking water in the buffer pressure barrel 603 from flowing back to the No. 2 pipe, and make the direct drinking water in the buffer pressure barrel 603 flow to the No. 6 pipe for the users of the top floor through the No. 8 pipe.

[0079] The normally closed pressure switch 602 with a disconnection pressure of 0.01 Mpa is a key component of the independently operated buffer pressure water supply mechanism 600, and when the pressure of the direct drinking water in the buffer pressure barrel 603 reaches 0.01 Mpa, the normally closed pressure switch 602 is disconnected, and the water preparation is stopped. The pressure of 0.01 Mpa is sufficient to make the direct drinking water in the buffer pressure barrel 603 of the floor flow to the indoor water tank 700 (mini water tank) of the user's home.

[0080] An indoor water tank 700 is independently installed above the kitchen ceiling of each user's home, with a height of 20 cm and a length x width of 25 cm x 25 m, so as to ensure that the flow and pressure of the direct drinking water faucet 703 of each user's home are consistent and are not affected by the pressure and flow of the direct drinking water pipeline in the pipeline well during the peak period of water use.

[0081] The storage capacity of the indoor water tank 700 should be controlled between 3.5-4L, which is less than the daily water consumption of a user (average 6L / house), and is constantly replenished and updated every day to ensure fresh water quality. The indoor water tank 700, together with the upper and lower water tanks in the pipeline well and the buffer pressure barrel 603, forms a complete buffer water supply system, which is suitable for the increasing number of users in the community and realizes the purpose of flexible water supply.

[0082] The indoor water tank 700 should be provided with a water outlet formed integrally with the tank body by injection molding at the bottom. There should be a slope of about 5 degrees between the tank bottom and the water outlet to form a funnel shape, so that the user can completely drain the water when cleaning the water tank. The indoor water tank 700 is provided with an upper floating ball valve 800.

[0083] If a user is out for more than 3 days, the second ball valve 115 should be closed, the direct drinking water faucet 703 is opened, and the direct drinking water in the indoor water tank 700 is drained. When the user returns, the second ball valve 115 and the direct drinking water faucet 703 are opened to drain water for 3 minutes, so that 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.

[0084] The upper and lower water tanks in the pipeline well are each provided with an independent ozone sterilization tank 111, which is sterilized and preserved for 40 minutes at 1 o'clock every night. After sterilization, the ozone naturally volatilizes only for more than 30 minutes, and the owner can use it safely after 5 o'clock.

[0085] The ozone sterilization tank 111 is composed of a transformer, a blower, an ozone generating pipe, a timer, an ozone output pipe and a gas diffusing ball extending into the bottom of the water tank.

[0086] The present application provides an implementation step of the above-mentioned pipeline direct drinking water system:

[0087] Step 1, installation step:

[0088] Step 1.1, taking tap water from the tap water meter 101 installed on the top floor.

[0089] Step 1.2, the tap water with pressure is sequentially passed through the low-pressure switch 103, the normally closed electromagnetic valve 104 of the tap water inlet mechanism 100, and then enters the first filtering mechanism 400 (PP cotton + activated carbon + PP cotton) hung in the top floor water meter well for primary filtration, to obtain primary filtration water without bleaching powder and silt impurities. At this time, the original pressure of the tap water consumed by the first filtering mechanism 400 is about 0.1 Mpa.

[0090] Step 1.3, the primary filtration water is put down 8-10 floors through the No. 1 pipe to increase the primary filtration water pressure by 0.24-0.3 Mpa. The number of floors to be put down is determined according to the pressure of the primary filtration water. The pressure of the primary filtration water before the RO membrane should be 0.5-0.7 Mpa. If the water pressure of the top floor is lower than 0.25 Mpa, the water supply room should be adjusted to increase the water pressure of the top floor to be greater than 0.25 Mpa.

[0091] Step 1.4, after the primary filtration water passes through the RO membrane, the water is divided into pure water and waste water. The waste water is discharged into the nearby sewer. The pure water is then filtered through the mineralization filter 503 to obtain minerals. After the third PP cotton 504 is filtered to remove small mineral particles, clean direct drinking water is obtained, and the pressure consumption is about 0.1 Mpa. The total filtration process consumes about 0.2 Mpa.

[0092] The tap water inlet mechanism 100 includes a tap water meter 101, a pressure gauge 102, a low pressure switch 103, and a normally closed electromagnetic valve 104. The pressure gauge 102 is only used to display the tap water pressure and does not have a functional effect on the entire filtration process.

[0093] The primary filtration water is filtered through the RO membrane to obtain pure water. The first RO membrane 501 and the second RO membrane 502 are connected in series. The primary filtration water first enters the first RO membrane 501. The waste water filtered by the first RO membrane 501 is filtered again by the second RO membrane 502. The waste water filtered by the second RO membrane 502 is discharged into the nearby sewer. The pure water filtered by the two RO membranes is combined and sent to the mineralization filter 503 and the third PP cotton to obtain direct drinking mineral water.

[0094] The first RO membrane 501 and the second RO membrane 502 are connected in series to improve the water purification rate of the system. Compared with the traditional single membrane filtration method, the water purification rate of the double membrane series filtration method is almost doubled. The water purification rate is increased from 35% of the single membrane filtration method to 65% of the double membrane series filtration method, greatly saving water resources.

[0095] Step 2, water storage method:

[0096] Step 2.1, the direct drinking water produced in step 1.4 flows out of the third PP cotton 504 into the No. 2 pipe. Due to the pressure difference, the direct drinking water is preferentially stored in the lower water tank 300 through the No. 2 pipe to the No. 7 pipe.

[0097] Step 2.2, when the lower water tank 300 is full, the upper floating ball valve 800 in the lower water tank 300 is closed, and the direct drinking water continues to be stored in the upper water tank 200 through the No. 2 pipe.

[0098] Step 2.3, when the upper water tank 200 is full, the upper ball of the float switch 900 in the upper water tank 200 rises, the normally closed of the 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, and the water level in the upper water tank 200 continues to rise until the upper float valve 800 in the upper water tank 200 floats up and closes, and then the direct drinking water enters the indoor water tank 700 on the top floor through the No. 2 pipe, the No. 8 pipe, and the No. 6 pipe.

[0099] Step 2.4, when the indoor water tank 700 on the top floor is full and the upper float valve 800 closes the water inlet, the direct drinking water enters the buffer pressure barrel 603 of the buffer pressure water supply mechanism 600 through the check valve, and until the water storage pressure in the buffer pressure barrel 603 rises to 0.01 Mpa, the normally closed pressure switch 602 is powered off, the tap water inlet mechanism 100 is closed, and the water production is stopped.

[0100] The installation height of the float switch 900 in the upper water tank 200 should be such that the water level required for the upper ball 901 to float up is lower than the water level at which the upper float valve 800 closes, so as to ensure that when the float valve 800 in the upper water tank 200 closes, the upper ball 901 of the float switch 900 has indeed floated up, and the relay 110 stops working.

[0101] Regardless of the situation, the water storage sequence is: the lower water tank 300, the upper water tank 200, the indoor water tank 700 of the user's home on the top floor, and the buffer pressure barrel 603.

[0102] Conditions and process of starting and stopping water production:

[0103] If the system is started for the first time or there is no water 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 the water production is started.

[0104] After the system is started for the first time and put into formal operation, when the user uses the water in the upper water tank 200 to lower the lower ball 902 of the float switch 900, the normally open of the relay is connected, the relay is started, and the water production is started.

[0105] If only the lower tank 300 is out of water, and the water level of the upper tank 200 is in the full water state, the lower ball 902 of the float switch 900 cannot drop to start the water making relay 110. 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 float ball valve 112 of the lower tank 300, causing the middle float ball valve 112 to automatically open, so that the direct drinking water in the upper tank 200 flows into the lower tank 300 through the No. 4 pipe and the No. 3 pipe in turn, 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 connects the normally open relay 110 to start water making.

[0106] After the system is initially started and put into formal operation, if only the direct drinking water in the buffer pressure tank 603 on the top floor causes the pressure to be less than 0.01 Mpa due to water supply to the top floor user, the normally closed pressure switch 602 is connected, the system supplies power to the normally closed electromagnetic valve 104, and water making is started.

[0107] When the water pressure in the buffer pressure tank 603 exceeds 0.01 Mpa, the normally closed pressure switch 602 is de-energized, and the electromagnetic valve in the upper tank is closed in the full water state, or when the tap water is stopped, the normally closed electromagnetic valve 104 stops water making.

[0108] Step 3, water supply method:

[0109] Step 3.1, the lower tank 300 naturally supplies water to the corresponding users of each floor through the No. 5 pipe, without the need for pressure boosting, and if necessary, only a pressure reducing valve is installed at an appropriate position of the No. 5 pipe to reduce the pressure.

[0110] Step 3.2, the upper tank 200 naturally supplies water to the corresponding users of each floor through the No. 4 pipe, without the need for pressure boosting.

[0111] The No. 4 pipe of the upper tank 200 can also supply water to the first floor, and if the floor is too high and the water supply pressure needs to be reduced, only a pressure reducing valve is installed at an appropriate position of the No. 4 pipe to reduce the pressure.

[0112] Step 3.3, the buffer pressure tank 603 supplies water to the top floor users through the No. 8 pipe and the No. 6 pipe.

[0113] Step 3.4, direct drinking water is provided to the top floor of a unit without a pipe direct drinking water system through the No. 2 pipe extension through the basement;

[0114] If the floor of a unit without a pipe direct drinking water system is the same height as the floor of a unit with a pipe direct drinking water system, an upper tank and a buffer pressure tank are provided on the top floor of the unit without a pipe direct drinking water system;

[0115] If the floor of the unit without the pipeline direct drinking water system is one floor or more below the floor of the unit with the pipeline direct drinking water system, only the upper water tank is arranged on the top floor of the unit without the pipeline direct drinking water system.

[0116] The above-mentioned step installation pressure reducing valve refers to if the water supply floor of the water supply system in the pipeline well is more than ten floors, a constant pressure pressure reducing valve should be arranged every ten floors to make the direct drinking water pressure into the user's home not more than 0.3Mpa.

[0117] The pipeline direct drinking water system provided in the embodiment can be installed by first embedding the direct drinking water pipeline sleeve under the sink basin in the pipeline well to the user's home. The embedding of the direct drinking water pipeline sleeve does not need to change the original design structure of the house, and the embedding construction of the new building and the tap water pipeline is synchronous, so that the investment cost is low. Even if the future occupants do not want to open the direct drinking water, the loss is small. When the residence is delivered for use, the number of open units is counted and the initial installation fee is collected. According to the number of open units required in advance, the water production equipment with appropriate power and the intelligent water meter matched with the number of in-home units are installed, and there is no idle intelligent water meter, so that excessive construction and idle investment are not generated.

[0118] If the elevator lobby of the old building has been pasted with ceramic tiles, the direct drinking water pipeline cannot be embedded on the ground. If the user's home and the pipeline well are separated by only one wall, a hole can be drilled to enter the kitchen ceiling in the user's home and be connected with the indoor water tank 700.

[0119] If the user's home and the pipeline well are not separated by only one wall, a walkway can be arranged above the elevator lobby, and a hole can be drilled to enter the kitchen ceiling in the user's home and be connected with the indoor water tank 700.

[0120] The in-home water tank 700 and the direct drinking water faucet 703 are installed in the kitchen ceiling of the user's home, and the 3rd direct drinking water pipe is connected between the in-home water tank 700 and the 4th direct drinking water faucet 703.

[0121] The 3rd direct drinking water pipe is inserted into the direct drinking water sleeve of the well and the kitchen, and is connected with the in-home direct drinking water meter 113 and the indoor water tank 700.

[0122] The pipeline direct drinking water system provided in the embodiment adopts a construction scheme and a water supply scheme of a building block type flexible water supply. The flexible water supply is a comprehensive concept, which is suitable for the characteristics of gradual increase of the number of users and step-by-step opening requirements in the construction of the pipeline direct drinking water system, and effectively avoids idle investment.

[0123] The pipeline direct drinking water system provided in the embodiment replaces the traditional water purification machine room with the tap water pipeline well of the high-rise building, and according to the filtration pressure required by each element of the purification equipment, the purification equipment is hung on different floors, the pressure difference between different floors is added by using the high-rise tap water pressure, and the sum of the two parts of pressure solves the pressure required by each filtration element, so that pump pressure boosting water production is realized.

[0124] By setting the appropriate size of the buffer pressure bucket, buffer water tank and set in the user's home water tank, constitute the water supply buffer system, the system automatically supplement the water storage, realize the elastic water supply. On the one hand, maintain the user's home tap straight drinking water pressure and flow constant, on the other hand, with the increasing number of users, realize the elastic water supply. Through this method to build the pipeline direct drinking water system, speed up the construction speed, reduce the construction cost and operation and maintenance cost, market application prospect is wide.

[0125] The above-mentioned is only the embodiment of the present application, and does not limit the patent range of the present application, any equivalent structure or equivalent flow transformation made by using the content of the specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection range of the present application.
