[0026] With the development of economy, in order to meet the water demand of people, the existing water supply system usually stores the water of municipal water network in the underground water tank of building first, and then supplies water to each floor area from the underground water tank, but in the water peak period, the water consumption of underground water tank is too fast, and the water quantity and water pressure are difficult to meet the water demand in the peak period, which affects the water use effect of residents.

[0027] The utility model provides a kind of water supply system, to solve the technical problem of how to improve the water supply effect of water supply system.

[0028] As shown in the utility model embodiment, Figure 1 The water supply system includes: water storage tank 10, the water storage tank 10 is used to communicate with municipal water network 30;Floor area water supply pipeline, the floor area water supply pipeline includes floor area water distribution pipeline 21 and the first water supply pipe 22 and the second water supply pipe 23 communicated with the floor area water distribution pipeline 21, the first water supply pipe 22 is communicated with the water storage tank 10, and the second water supply pipe 23 is used to communicate with municipal water network 30.

[0029] In the embodiment, municipal water network 30 can provide the tap water that is produced after purification and disinfection and meets corresponding standards for people's life and production. The water storage tank 10 is usually arranged underground, and the water storage tank 10 can store water from the municipal water network 30, and then the water is delivered to the water terminal such as faucet when the residents in the floor area take water. The water storage tank 10 is communicated with the municipal water network 30, so when the water in the water storage tank 10 is consumed, the water can be automatically supplemented in time through the municipal water network 30. The floor area water distribution pipeline 21 is communicated with the water terminal of each floor, and the floor area water distribution pipeline 21 is communicated with the water storage tank 10 through the first water supply pipe 22, so that the water in the water storage tank 10 can flow to the floor area water distribution pipeline 21 through the first water supply pipe 22. The floor area water distribution pipeline 21 is also directly communicated with the municipal water network 30 through the second water supply pipe 23, so that the water of the municipal water network 30 can flow to the floor area water distribution pipeline 21 through the second water supply pipe 23.

[0030] In the water peak period, for example, the time period when the residents in the building area cook in the evening or the time period when the residents take a bath in the evening, the demand for water quantity and water pressure is higher because the residents use water more concentratedly in these time periods. Since the building area water supply pipeline is connected with the water storage tank 10 and the municipal water network 30, the building area water supply pipeline can be supplied with water by the water storage tank 10 and the municipal water network 30 at the same time at this time, so as to ensure the water quantity and water pressure when the residents use water, so as to improve the water supply effect of the water supply system. The water supply system can further include a second control valve arranged at the first water supply pipe 22, when it is needed to clean the water storage tank 10, the water path of the first water supply pipe 22 can be cut off by the second control valve at first, at this time, the building area water supply pipeline can be supplied with water by the municipal water network 30, so as to clean the water storage tank 10 to reduce secondary pollution, and prevent the building area from stopping water supply, so as to improve the water use effect of the residents.

[0031] Specifically, as shown in Figure 1 the water storage tank 10, at this time, the water in the water storage tank 10 can be used reasonably. In the water peak period, the water quantity and water pressure in the water storage tank 10 are insufficient to meet the water use of the residents in the building area, at this time, the second water supply pipe 23 can be turned on by the first control valve 43, so that the municipal water network 30 can supply the building area water supply pipeline with water in time to meet the water use demand of the residents in the peak period.

[0032] In actual application, the water supply system further includes a main control circuit and a water level sensor, the first control valve 43 is an electric control valve, the first control valve 43 and the water level sensor are electrically connected with the main control circuit, the water level sensor is used to detect the water level of the water storage tank 10, and the main control circuit is used to control the first control valve 43 to turn on the second water supply pipe 23 when the water level of the water storage tank 10 is lower than or equal to a preset water level, wherein the preset water level is lower than the automatic water replenishment water level of the water storage tank 10.

[0033] The water storage tank 10 is communicated with the municipal water network 30 through a water supplement pipeline. The water storage tank 10 can realize automatic water supplement through a floating ball valve. When the water level of the water storage tank is lower than the automatic water supplement level, the floating ball valve opens the water supplement pipeline, so that the municipal water network 30 supplements water to the water storage tank 10. When the water level of the water storage tank is higher than or equal to the automatic water supplement level, the floating ball valve closes the water supplement pipeline, so that the municipal water network 30 stops supplementing water to the water storage tank 10. The first control valve 43 can be an electromagnetic valve. When the water level of the water storage tank 10 is lower than or equal to the preset water level, it indicates that the water of the water storage tank 10 is being rapidly consumed, and the consumption speed is greater than the automatic water supplement speed, which indicates that the water demand of the building area is large at this time. Therefore, the main control circuit needs to control the first control valve 43 to conduct the second water supply pipe 23, so that the municipal water network 30 can supplement water to the building area through the second water supply pipe 23 in time. In this way, automatic control of the first control valve 43 can be realized, so as to realize automatic control of the conduction or disconnection of the second water supply pipe 23, and the intelligent effect of the water supply system is improved.

[0034] For example, the main control circuit includes a trigger circuit. When the water level detected by the water level sensor is lower than or equal to the preset water level, the trigger circuit triggers the first control valve 43 to conduct the second water supply pipe 23. When the water level detected by the water level sensor is higher than the preset water level, the trigger circuit triggers the first control valve 43 to disconnect the second water supply pipe 23.

[0035] For example, as shown in Figure 1 The water supply system further includes a first driving water pump 41, which is communicated with the second water supply pipe 23 and is used to drive the water flow of the municipal water network 30 to the building area water supply pipeline 21. The water inlet end of the first driving water pump 41 is communicated with the municipal water network 30, and the water outlet end is communicated with the second water supply pipe 23. The first driving water pump 41 can drive the water flow of the municipal water network 30 to flow to the building area water supply pipeline at a preset water pressure, so that the water flow flows to the water consumption terminal of the building area at a preset water pressure, so as to meet the water consumption demand of the building area, prevent the residents from being inconvenient due to the small water pressure of the municipal water network 30, and further improve the water supply effect of the water supply system.

[0036] The output power of the first driving water pump 41 can be fixed or adjustable. If the output power of the first driving water pump 41 is fixed, the water pressure of the water flow driven by the first driving water pump 41 is also fixed. If the second water supply pipe 23 is affected by other factors to cause the water pressure in the pipe to increase or decrease, it is difficult to adjust the first driving water pump 41 to keep the water pressure in the preset range.

[0037] Specifically, the water supply system further comprises a main control circuit, a first frequency converter and a first water pressure sensor, the first driving water pump 41, the first water pressure sensor and the first frequency converter are electrically connected with the main control circuit, the first water pressure sensor is used to detect the water pressure of the building area water distribution pipeline 21, and the frequency converter is used to adjust the output power of the first driving water pump 41.

[0038] The first water pressure sensor can detect the water pressure of the second water supply pipe 23 in real time and transmit the detected water pressure information to the main control circuit, and the main control circuit sends a control signal to the first frequency converter according to the water pressure information, so as to increase or decrease the output power of the first driving water pump 41 through the first frequency converter, so as to adjust the driving water pressure of the first driving water pump 41, so that the water pressure of the second water supply pipe 23 can be kept in a stable interval.

[0039] For example, the main control circuit comprises a trigger circuit, which is used to trigger the first frequency converter to control the first driving water pump 41 to work at a first power when the water pressure detected by the first water pressure sensor is less than or equal to a trigger threshold, and to control the first driving water pump 41 to work at a second power when the water pressure detected by the first water pressure sensor is greater than the trigger threshold; the second power is less than the first power.

[0040] For example, as shown in Figure 1 The water supply system further comprises a second driving water pump 42, which is in communication with the first water supply pipe 22 and is used to drive the water flow in the water storage tank 10 to flow to the building area water distribution pipeline 21. The water inlet end of the second driving water pump 42 is in communication with the water storage tank 10, and the water outlet end is in communication with the first water supply pipe 22. The second driving water pump 42 can drive the water flow in the water storage tank 10 to flow to the building area water supply pipeline at a preset water pressure, so that the water flow flows to the water terminal of the building area at a preset water pressure, so as to meet the water demand of the building area, prevent the residents from being inconvenient due to the too small water pressure in the water storage tank 10, and further improve the water supply effect of the water supply system.

[0041] The output power of the second driving water pump 42 can be fixed or adjustable. If the output power of the second driving water pump 42 is fixed, the water pressure of the water flow driven by the second driving water pump 42 is also fixed. If the first water supply pipe 22 is affected by other factors to cause the water pressure in the pipe to increase or decrease, it is difficult to keep the water pressure in the preset interval by adjusting the second driving water pump 42.

[0042] Specifically, the water supply system further comprises a main control circuit, a second frequency converter and a second water pressure sensor, the main control circuit is electrically connected with the second frequency converter, the second driving water pump 42 and the second water pressure sensor; the second water pressure sensor is used to detect the water pressure of the first water supply pipe 22, and the second frequency converter is used to adjust the output power of the second driving water pump 42.

[0043] The second water pressure sensor can detect the water pressure of the first water supply pipe 22 in real time, and transmit the detected water pressure information to the main control circuit, and the main control circuit sends a control signal to the second frequency converter according to the water pressure information, so as to increase or decrease the output power of the second driving water pump 42 through the second frequency converter, so as to adjust the driving water pressure of the second driving water pump 42, so that the water pressure of the first water supply pipe 22 can be kept in a stable range.

[0044] In actual application, as shown in Figure 1 The water supply system further comprises a one-way valve 45, which is arranged in the second water supply pipe 23. The one-way valve 45 can prevent the water flow of the building area water supply pipeline from flowing back to the municipal water network 30, so as to ensure the stability of the water supply of the building area water supply pipeline. The water supply system can further comprise a water purifier 44, which is arranged in the second water supply pipe 23, so as to filter the water from the municipal water network 30, improve the cleanliness of the water flowing to the water terminal, and further improve the water supply effect of the water supply system.

[0045] As shown in Figure 2 The building area water distribution pipeline 21 comprises a first water distribution pipe 211, a second water distribution pipe 212, a communication pipe 213 and a pressure reducing valve 214, the first water distribution pipe 211 is used to supply water to the first building area, the second water distribution pipe 212 is used to supply water to the second building area, wherein the altitude of the first building area is higher than that of the second building area; the communication pipe 213 communicates the first water distribution pipe 211 with the second water distribution pipe 212, and the pressure reducing valve 214 is arranged in the communication pipe 213, and the pressure reducing valve 214 is used to reduce the water pressure of the water flow from the first water distribution pipe 211 to the second water distribution pipe 212.

[0046] The first building area and the second building area can be different building areas of the same building, or different building areas of different buildings, which are not limited here. The first building area can include only one floor, or two floors or more; the second building area can include only one floor, or two floors or more; it can be understood that if the number of floors of the first building area and the second building area is multiple floors, the altitude of the lowest floor of the first building area is higher than that of the highest floor of the second building area. Because the altitude of the first building area is higher, the water pressure required to drive the water flow to the first building area will be greater than the water pressure required to drive the water flow to the second building area.

[0047] The first water distribution pipe 211 is a main water supply pipe of the first floor area, and the floor area water distribution pipeline 21 can further include a plurality of first sub-distribution pipes in communication with the first water distribution pipe 211 to distribute water flow to different water outlet terminals. The second water distribution pipe 212 is a main water supply pipe of the second floor area, and the floor area water distribution pipeline 21 can further include a plurality of second sub-distribution pipes in communication with the second water distribution pipe 212 to distribute water flow to different water outlet terminals.

[0048] The water inlet end of the second driven water pump 42 is in communication with the water source, and the water outlet end is in communication with the first water distribution pipe 211. The second driven water pump 42 can first drive water flow to the first water distribution pipe 211 at a first preset water pressure, which is greater than or equal to the water pressure required for normal water use in the first floor area. Thus, the second driven water pump 42 can drive water flow to flow directly to the water use terminals of the first floor area through the first water distribution pipe 211 at the first preset water pressure to meet the water use demand of the first floor area.

[0049] Since the second water distribution pipe 212 is in communication with the first water distribution pipe 211, under the action of the second driven water pump 42, water flow will also flow to the second water distribution pipe 212 through the communication pipe 213. Under the action of the second driven water pump 42, water flow flows into the communication pipe 213 at the first preset water pressure, and will flow through the pressure reducing valve 214 before flowing out of the communication pipe 213. The pressure reducing valve 214 is a valve that reduces the inlet pressure to a required outlet pressure by adjustment and relies on the energy of the medium itself to automatically maintain the stability of the outlet pressure. Thus, the pressure reducing valve 214 can adjust the water flow flowing out of the communication pipe 213 to a second preset water pressure, so that the water flow can flow into the second water distribution pipe 212 at the second preset water pressure. The second preset water pressure is less than the first preset water pressure, and is within the water pressure range required for normal water use in the second floor area, so as to control the water flow rate to the second floor area within a reasonable range to meet the normal water use demand.

[0050] It can be understood that since the altitude of the first floor area is higher than that of the second floor area, if the working water pressure of the second driven water pump 42 can meet the normal water use demand of the first floor area, it can also meet the normal water use demand of the second floor area. The pressure reducing valve 214 can control the water flow to the second floor area within a reasonable water pressure range. Therefore, only one second driven water pump 42 and one pressure reducing valve 214 can meet the normal water use demand of two floor areas with different altitudes, thereby reducing the number of second driven water pumps 42, simplifying the structure of the water supply system, and reducing the energy consumption of the water supply system during operation.

[0051] The utility model discloses still put forward a kind of building, the building includes building area and water supply system, the specific structure of this water supply system refers to above-mentioned embodiment, since the building adopts all technical solutions of above-mentioned all embodiments, therefore at least have all beneficial effects brought by the technical scheme of above-mentioned embodiment, here no longer repeat.

[0052] The above is only optional embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made under the inventive concept of the utility model, using the utility model specification and the contents of the drawings, or direct / indirect application in other related technical fields are included in the patent protection range of the utility model.
