[0029] 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 water storage tank under the building first, and then supplies water to each building area from the water storage tank, but in the water peak period, the water consumption in the water storage 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.

[0030] 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.

[0031] In the embodiments of the utility model, as shown in Figure 1 The water storage tank 10 is used to communicate with municipal water network 20;Building area water supply pipeline, the building area water supply pipeline includes building area water distribution pipeline 31, commonly used communication flow path 32, backup communication flow path 33 and connecting pipe 34, the commonly used communication flow path 32 and the backup communication flow path 33 are connected in parallel, the commonly used communication flow path 32 and backup communication flow path 33 communicate the building area water distribution pipeline 31 with the connecting pipe 34;The connecting pipe 34 is communicated with the water storage tank 10 by first water supply pipe 41, and the connecting pipe 34 is also used to communicate with municipal water network 20 by second water supply pipe 42;First control valve 51, the first control valve 51 is arranged in the backup communication flow path 33, to control the backup communication flow path 33 to be conducted or disconnected.

[0032] In the embodiment, the municipal water network 20 can provide the tap water produced after purification and disinfection, which meets the corresponding standards and is used for people's life and production. The water storage tank 10 is usually arranged underground, and can store the water from the municipal water network 20, and then deliver the water to the water faucet when the residents in the building area take water. The water storage tank 10 is communicated with the municipal water network 20, so that when the water in the water storage tank 10 is consumed, the water can be automatically replenished in time through the municipal water network 20. The building water distribution pipeline 31 is communicated with the water terminal of each floor, and is communicated with the connecting pipe 34 through the normal communication flow path 32, and the connecting pipe 34 is communicated with the water storage tank 10 and the municipal water network 20 through the first water supply pipe 41 and the second water supply pipe 42 respectively, so that the water in the water storage tank 10 can flow to the building water distribution pipeline 31 through the first water supply pipe 41, the connecting pipe 34 and the normal communication flow path 32, and the water of the municipal water network 20 can flow to the building water distribution pipeline 31 through the second water supply pipe 42, the connecting pipe 34 and the normal communication flow path 32.

[0033] During the peak water consumption period, for example, during the period when the residents in the building area cook in the evening or take a bath at night, the demand for water quantity and water pressure is higher due to the concentrated water consumption of the residents during the period. Since the building water supply pipeline is communicated with both the water storage tank 10 and the municipal water network 20, the building water supply pipeline can supply water through both the water storage tank 10 and the municipal water network 20 at this time, so as to ensure the water quantity and water pressure during the water consumption of the residents, thereby improving the water supply effect of the water supply system. The water supply system can further include a fourth control valve arranged in the first water supply pipe 41, when it is necessary to clean the water storage tank 10, the fourth control valve can be used to cut off the water path of the first water supply pipe 41, at this time, the building water supply pipeline can be supplied with water by the municipal water network 20, so as to clean the water storage tank 10 and reduce secondary pollution, and prevent the building area from stopping water supply, thereby improving the water consumption effect of the residents.

[0034] The standby communication flow path 33 can also communicate the building water distribution pipeline 31 with the connecting pipe 34, if the normal communication flow path 32 is in normal working state, the first control valve 51 controls the standby communication flow path 33 to be disconnected, at this time, the standby communication flow path 33 is in idle state, and the water of the water storage tank 10 and the municipal water network 20 flows to the building water distribution pipeline 31 through the normal communication flow path 32. If the second water supply pipe 42 is in maintenance state, the first control valve 51 controls the standby communication flow path 33 to be connected, at this time, the water in the water storage tank 10 can flow to the building water distribution pipeline 31 through the first water supply pipe 41, the connecting pipe 34 and the standby communication flow path 33, and the water of the municipal water network 20 can flow to the building water distribution pipeline 31 through the second water supply pipe 42, the connecting pipe 34 and the standby communication flow path 33. Therefore, even if the normal communication flow path 32 is in maintenance state, the standby communication flow path 33 can be connected to ensure the normal working of the water supply system.

[0035] Specifically, as shown in FIG. 1, the water supply system can include a water storage tank 10, a building water distribution pipeline 31, a connecting pipe 34, a first water supply pipe 41, a second water supply pipe 42, a normal communication flow path 32, a standby communication flow path 33, a first control valve 51, a second control valve 52, a third control valve 53 and a fourth control valve 54. Figure 1As shown, the water supply system further comprises a second control valve 52 arranged in the second water supply pipe 42 to control the second water supply pipe 42 to be connected or disconnected. During the non-peak period of water consumption, the water in the water storage tank 10 is sufficient to meet the water consumption of the residents in the building area, at this time, the water supply pipeline of the building area does not need to be supplied by the municipal water network 20, therefore, the second control valve 52 can control the second water supply pipe 42 to be disconnected, so that the water in the water storage tank 10 can be reasonably used. During the peak period of water consumption, the water amount and water pressure in the water storage tank 10 are insufficient to meet the water consumption of the residents in the building area, at this time, the second control valve 52 can control the second water supply pipe 42 to be connected, so that the municipal water network 20 can supply water to the water supply pipeline of the building area in time to meet the water consumption demand of the residents during the peak period.

[0036] In actual application, the water supply system further comprises a main control circuit and a water level sensor, the second control valve 52 is an electric control valve, the second control valve 52 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 second control valve 52 to connect the second water supply pipe 42 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.

[0037] The water storage tank 10 is communicated with the municipal water network 20 through a water replenishment pipeline, the water storage tank 10 can realize automatic water replenishment through a float ball valve, when the water level of the water storage tank 10 is lower than the automatic water replenishment water level, the float ball valve opens the water replenishment pipeline, so that the municipal water network 20 replenishes water to the water storage tank 10; when the water level of the water storage tank 10 is higher than or equal to the automatic water replenishment water level, the float ball valve closes the water replenishment pipeline, so that the municipal water network 20 stops replenishing water to the water storage tank 10. The second control valve 52 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 in the water storage tank 10 is being consumed rapidly, and the consumption speed is greater than the automatic water replenishment speed, which indicates that the water consumption demand of the building area is large at this time, therefore, the main control circuit needs to control the second control valve 52 to connect the second water supply pipe 42, so that the municipal water network 20 can supply water to the building area through the second water supply pipe 42 in time. In this way, the automatic control of the second control valve 52 can be realized, so as to realize the automatic control of the second water supply pipe 42 to be connected or disconnected, and the intelligent effect of the water supply system is improved.

[0038] For example, the main control circuit comprises a trigger circuit, which is used to trigger the second control valve 52 to connect the second water supply pipe 42 when the water level of the water storage tank 10 detected by the water level sensor is lower than or equal to the preset water level, and trigger the second control valve 52 to disconnect the second water supply pipe 42 when the water level of the water storage tank 10 detected by the water level sensor is higher than the preset water level.

[0039] The normal communication flow path 32 and the standby communication flow path 33 can be a water pump, can be a pipeline, or can comprise a pipeline and a water pump installed in the pipeline, which is not limited here.

[0040] As shown in the figure, the normal communication flow path 32 comprises a normal water pump 61, the water inlet end of which is communicated with the connecting pipe 34, and the water outlet end of which is communicated with the building area water distribution pipeline 31; the standby communication flow path 33 comprises a standby water pump 62, the water inlet end of which is communicated with the connecting pipe 34, and the water outlet end of which is communicated with the building area water distribution pipeline 41; the normal water pump 61 and the standby water pump 62 are used to drive the water flow of the municipal water network 20 and the water storage pool 10 to the building area water distribution pipeline 31. The first control valve 51 is arranged upstream of the water inlet end of the standby water pump 62.

[0041] The water inlet ends of the normal water pump 61 and the standby water pump 62 are respectively communicated with the municipal water network 20 and the water storage pool 10, and the water outlet ends thereof are respectively communicated with the normal communication flow path 32 and the standby communication flow path 33. The normal water pump 61 and the standby water pump 62 can drive the water flow of the municipal water network 20 and the water storage pool 10 to flow to the building area water distribution 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 to meet the water demand of the building area, thereby preventing the residents from being inconvenient in using water due to the too small water pressure of the municipal water network 20 and the water storage pool 10, and further improving the water supply effect of the water supply system. It can be understood that the normal water pump 61 and the standby water pump 62 are opened alternatively, and in general, the normal water pump 61 is opened preferentially, and only when the normal communication flow path 32 is disabled, the standby water pump 62 is considered to be opened.

[0042] The output power of the normal water pump 61 and the standby water pump 62 can be fixed or adjustable. If the output power of the normal water pump 61 and the standby water pump 62 is fixed, the water pressure of the water flow driven by the normal water pump 61 and the standby water pump 62 is also fixed, and if the second water supply pipe 42 and the standby communication flow path 33 are affected by other factors to cause the water pressure in the pipe to increase or decrease, it is difficult to maintain the water pressure in the preset range by adjusting the normal water pump 61 and the standby water pump 62.

[0043] Specifically, the water supply system further comprises a main control circuit, a first frequency converter and a first water pressure sensor, the normal water pump 61, the standby water pump 62, 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 31, and the frequency converter is used to adjust the output power of the normal water pump 61 and the standby water pump 62.

[0044] The first water pressure sensor can detect the water pressure of the normal communication flow path 32 and the standby communication flow path 33 in real time, and transmit the detected water pressure information to the main control circuit. The main control circuit can send 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 normal water pump 61 and the standby water pump 62 through the first frequency converter, thereby adjusting the driving water pressure of the normal water pump 61 and the standby water pump 62. In this way, the water pressure of the normal communication flow path 32 and the standby communication flow path 33 can be kept in a stable range.

[0045] For example, the main control circuit includes a trigger circuit. When the water pressure detected by the first water pressure sensor is less than or equal to a trigger threshold, the trigger circuit triggers the first frequency converter to control the normal water pump 61 to work at a first power. When the water pressure detected by the first water pressure sensor is greater than the trigger threshold, the trigger circuit triggers the first frequency converter to control the normal water pump 61 to work at a second power. The second power is less than the first power.

[0046] In actual application, as shown in Figure 1 The standby communication flow path 33 includes a first one-way valve 63, which is arranged downstream of the water outlet end of the standby water pump 62. The normal communication flow path 32 includes a second one-way valve 64, which is arranged downstream of the water outlet end of the normal water pump 61. The first one-way valve 63 and the second one-way valve 64 can prevent the water flow of the building water supply pipeline from flowing back to the municipal water network 20 or the water storage tank 10, thereby ensuring the stability of the water supply of the building water supply pipeline. The water supply system can further include a first water purifier and a second water purifier, which are arranged in the first water supply pipe 41 and the second water supply pipe 42, respectively, to filter the water from the municipal water network 20 and improve the cleanliness of the water flowing to the water terminal, thereby further improving the water supply effect of the water supply system.

[0047] For example, as shown in Figure 1 The water supply system further includes a third control valve 53, which is arranged in the normal communication flow path 32 to control the conduction or disconnection of the normal communication flow path 32. The third control valve 53 is arranged upstream of the water inlet end of the normal water pump 61. When it is necessary to maintain and repair the normal communication flow path 32 or the functional components on the normal communication flow path 32, the water flow of the normal communication flow path 32 can be disconnected through the third control valve 53, thereby facilitating the subsequent maintenance and repair operation.

[0048] Specifically, the water supply system further comprises a main control circuit and a switch sensor, the first control valve 51 is an electric control valve, and the first control valve 51 and the switch sensor are electrically connected with the main control circuit; the switch sensor is installed on the third control valve 53 to detect the opening and closing state of the third control valve 53; and the main control circuit is used to control the first control valve 51 to turn on or turn off the standby communication flow path 33 according to the opening and closing state of the third control valve 53.

[0049] The switch sensor can detect whether the third control valve 53 is in the on state or the off state and generate a corresponding switch signal, and the main control circuit controls the first control valve 51 to turn on or turn off according to the switch signal. When the third control valve 53 is in the on state, the main control circuit controls the first control valve 51 to turn off the standby communication flow path 33; and when the third control valve 53 is in the off state, the main control circuit controls the first control valve 51 to turn on the standby communication flow path 33. In this way, the first control valve 51 can be automatically switched to the opposite opening and closing state of the third control valve 53, thereby improving the intelligent effect of the water supply system.

[0050] In actual application, as shown in Figure 2 The building area water supply pipeline 31 comprises a first water supply pipe 35, a second water supply pipe 36, a communication pipe 37 and a pressure reducing valve 38. The first water supply pipe 35 is used to supply water to the first building area, and the second water supply pipe 36 is used to supply water to the second building area. The altitude of the first building area is higher than that of the second building area. The communication pipe 37 communicates the first water supply pipe 35 and the second water supply pipe 36, and the pressure reducing valve 38 is arranged in the communication pipe 37. The pressure reducing valve 38 is used to reduce the water pressure of the water flow from the first water supply pipe 35 to the second water supply pipe 36.

[0051] 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 herein. The first building area can include only one floor, or two floors or more; and 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, the altitude of the lowest floor of the first building area is higher than that of the highest floor of the second building area. Since the altitude of the first building area is higher, the water pressure required to drive the water flow to the first building area is greater than the water pressure required to drive the water flow to the second building area.

[0052] The first distribution pipe 35 is a main water supply pipe of the first floor area, and the floor area distribution pipe 31 can further include a plurality of first sub-distribution pipes in communication with the first distribution pipe 35 to distribute water flow to different water outlet terminals. The second distribution pipe 36 is a main water supply pipe of the second floor area, and the floor area distribution pipe 31 can further include a plurality of second sub-distribution pipes in communication with the second distribution pipe 36 to distribute water flow to different water outlet terminals.

[0053] The water inlet end of the standby water pump 62 is in communication with the water source, and the water outlet end is in communication with the first distribution pipe 35. The standby water pump 62 can first drive water flow to the first distribution pipe 35 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 standby water pump 62 can drive water flow to directly flow to the water use terminals of the first floor area through the first distribution pipe 35 at the first preset water pressure to meet the water use demand of the first floor area.

[0054] Since the second distribution pipe 36 is in communication with the first distribution pipe 35, under the action of the standby water pump 62, water flow can flow from the higher first floor area to the lower second floor area through the communication pipe 37, i.e., water flow can flow from the first distribution pipe 35 to the second distribution pipe 36. Under the action of the standby water pump 62, water flow flows into the communication pipe 37 at the first preset water pressure, and before flowing out of the communication pipe 37, water flow flows through the pressure reducing valve 38. The pressure reducing valve 38 is a valve that reduces the inlet pressure to a required outlet pressure by adjusting and relies on the energy of the medium itself to automatically maintain the stability of the outlet pressure. Thus, the pressure reducing valve 38 can adjust the water flow flowing out of the communication pipe 37 to a second preset water pressure, so that water flow can flow into the second distribution pipe 36 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 that the water flow rate of the second floor area can be controlled within a reasonable range to meet the normal water use demand.

[0055] 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 standby water pump 62 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 38 can control water flow flowing to the second floor area within a reasonable water pressure range. Thus, only one standby water pump 62 and one pressure reducing valve 38 can meet the normal water use demand of two floor areas with different altitudes, so that the number of standby water pumps 62 can be reduced to simplify the structure of the water supply system and reduce the energy consumption of the water supply system during operation.

[0056] 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.
