Description
Technical Field
The invention relates to the field of water supply, in particular to a negative-pressure-free energy-saving water supply system for a high-rise building.
Background
The municipal water supply network conveys domestic water to buildings governed by the municipal administration, the water pressure in the municipal water supply network is between a high value and a low value every day, for example, the high value and the low value are 0.45MPa and 0.25MPa respectively, and for the high buildings above 7 floors, the water pressure in the municipal water supply network can not meet the water supply requirements of the high buildings. In order to meet the water supply requirement of the high building, a high building secondary water supply system with a pressure water pump needs to be established, and a municipal water supply network and the high building secondary water supply system work in a combined manner to meet the water supply requirement of the high building. In order to avoid the influence on the water pressure in the municipal water supply network, the high-rise secondary water supply system is not allowed to generate negative pressure for the municipal water supply network connected with the high-rise secondary water supply system during the operation. However, the existing high-rise non-negative pressure water supply system has certain disadvantages: firstly, the existing high-rise water supply system stores a certain water source in advance by arranging a buffer tank, but the water source water tank is easy to cause pollution problems because the water source water tank not only has an overflow port but also is not completely sealed, and in addition, the water source water tank is required to be cleaned regularly to avoid water quality deterioration, thereby causing waste of water resources; secondly, the pressure of the water supply in the municipal water supply network is released after the water supply enters the water source water tank, and then the water in the water source water tank is sucked and pressurized by the pressurized water pump of the secondary water supply system, so that the serious waste of the water supply pressure energy in the municipal water supply network with certain pressure is caused; third, in order to consider the peak water consumption of the high-rise building, a large-volume water source tank needs to be constructed, which in turn increases the construction cost of the high-rise secondary water supply system.
In view of the above, the present invention is particularly proposed.
