Background
At present, more and more high buildings are provided, and the traditional pressurizing pump directly pressurizes water to supply water, so that a great amount of energy is wasted. The energy-saving water supply uses a municipal water supply pipe network as a water source, and utilizes the primary pressure of the municipal water supply pipe network to form a pressure superposition water supply mode of a closed space, thereby achieving the purpose of energy saving. It is the development and extension of the pressurization or variable frequency constant pressure water supply mode.
The current water supply methods are generally classified into direct water supply and pressurized water supply, and the most common water supply method is pressurized water supply for high-rise buildings. The pressurized water supply is generally carried out in three ways: the first is to store tap water in a basin and supply the tap water to a user through a booster pump. The water supply mode is easy to pollute, and the water is directly pressurized to users through the water pump, thereby wasting a large amount of energy. The second is to connect the municipal water supply network with the closed water tank and then supply the water directly to the user through the frequency conversion pressurizing unit. This approach tends to create negative pressure on the municipal water supply network, resulting in too little water supply pressure for the surrounding user. The third is that no negative pressure stationary flow water feeder that the recent years released constitutes complete sets, has both utilized municipal water supply network's primary pressure, has practiced thrift the energy, can not produce the negative pressure to municipal water supply network again. However, under the condition that the water pressure of the municipal water supply network is reduced, water in the water tank flows back, so that the water quality of the municipal water supply network is polluted.

Furthermore, the microcontroller is installed in a control terminal, for example, the microcontroller may be installed in a computer of a monitoring person, or may be installed in a control room of a monitoring department.
The utility model discloses a theory of operation does: when the water tank is used, once the municipal water supply network 5 supplies water, tap water enters the water tank 1 through the municipal water supply network 5, when the liquid level reaches the lowest liquid level, the variable frequency water pump 2 starts to work, and the microcontroller adjusts the power frequency of the variable frequency water pump 2 according to the detection result of the user pipe network pressure sensor 8, so that the pressure of the user pipe network 6 is always maintained at constant pressure; when the liquid level reached full liquid level, microcontroller control linked to each other discharge valve 3 closed, and water tank 1 forms airtight environment, and the pressure transmission of a pipe network to water tank 1, the pressure of a pipe network is utilized, and frequency conversion water pump 2 automatically regulated power frequency economizes down some energy.
Water supply without negative pressure: at the water peak period, when user's water consumption is greater than municipal water supply pipe network 5's water supply volume, variable frequency water pump 2 can produce the negative pressure to municipal water supply pipe network 5, can produce the negative pressure in the water tank 1, for preventing the negative pressure production, in case water tank pressure sensor 4 records pressure and is less than 0Pa, microcontroller control discharge valve 3 is opened, water tank 1 communicates with each other with the atmosphere, and the negative pressure disappears in the water tank, can not produce the negative pressure to municipal water supply pipe network 5 promptly. At the moment, the variable frequency water pump 2 independently provides pressure for the user pipe network. When the liquid level in the water tank 1 continuously drops and is lower than the lowest liquid level, the microcontroller controls the variable frequency water pump 2 to stop working. When the water consumption descends, the water supply amount is greater than the water consumption amount, the liquid level in the water tank 1 rises, the microcontroller controls the exhaust valve 3 to close after the liquid level reaches the full liquid level, the water tank 1 forms a closed environment again, water is supplied by utilizing the pressure of a pipe network, and the liquid level judgment is repeated.
Supplying water without backflow: under the circumstances that municipal water supply network 5 water pressure descends, when the pressure in the water tank 1 is greater than municipal water supply network 5's water pressure (this can be realized through the testing result of comparing inlet pipe pressure sensor 7 in water tank pressure sensor 4 and the municipal water supply network 5), can take place to flow back, and microcontroller control water tank 1 top discharge valve 3 opens. The exhaust valve 3 is closed again a few seconds after the pressure in the water tank 1 is released, and the closed environment is formed again. Pressure in the water tank 1 can reach the equilibrium again after with municipal water supply network 5's water pressure a period, and pressure reaches municipal water supply network 5's water supply pressure, and water can not take place the backward flow, and the power frequency of a pressure stack variable frequency water pump 2 is the once more water pressure of 6 water supplies reuse of user's pipe network simultaneously, and electric automatic control is simple, has realized full-automatic unmanned on duty control.
Water cut-off protection: when water is cut off, namely the pressure measured by the water inlet pipe pressure sensor 7 in the water inlet pipe is 0, the microcontroller controls the exhaust valve 3 to be opened. Because the water tank 1 has a certain water storage capacity, the user can normally supply water for a period of time. When the liquid level in the water tank 1 is lower than the lowest liquid level, the microcontroller controls the variable frequency water pump 2 to stop working, so that idling is avoided, and equipment is protected. After the water supply is normal and the liquid level is higher than the lowest liquid level, the microcontroller controls the variable frequency water pump 2 to start working. After the liquid level in the water tank reaches the maximum liquid level, the microcontroller controls the exhaust valve 3 to close, a closed environment is formed in the water tank 1, and primary pressure is utilized. The whole control is completed by a microcontroller, and intelligent control is realized.
