Energy-saving type non-negative-pressure water supply system for tall building

Abstract

The invention provides an energy-saving type non-negative-pressure water supply system for a tall building. A municipal water supply inlet pipe is connected with an inlet end of an auxiliary water supply pipe and an inlet end of a main water supply pipe through a tee pipe coupling; an outlet end of the auxiliary water supply pipe and an outlet end of the main water supply pipe are respectively connected with one tee pipe coupling, and an outlet end of the tee pipe coupling is connected with an inlet end of a water supply pipe for the tall building. The main water supply pipe is sequentially connected with a third stop valve, a main variable frequency pump, a third pressure gage and a tall building pressure-stabilizing tank in series. According to the energy-saving type non-negative-pressure water supply system, pressure-superposed adjustment can be carried out according to the water use amounts of different time periods, so that the secondary water supply at the peak water use periods of the tall building is guaranteed, and negative pressure can not be caused to a municipal water supply network; all water supply energies in the municipal water supply network can be utilized, so that the power consumption of a booster pump in a secondary water supply system is the minimum; a water-source water tank can not cause water quality pollution; the volume of the water-source water tank is reduced under the premise that the water use amounts of the water use periods of the tall building are guaranteed, and thus the construction cost of the secondary water supply system of the tall building is reduced.

Description

technical field [0001] The invention relates to the field of building water supply, and is an energy-saving high-rise non-negative pressure water supply system. Background technique [0002] The municipal water supply network delivers domestic water to the buildings under the jurisdiction of the municipality. The water pressure in the municipal water supply network is between the high value and the low value every day, for example, the high value and the low value are 0.45MPa and 0.25MPa respectively. , the water pressure in the municipal water supply network cannot meet the water supply needs of high-rise buildings. In order to meet the water supply demand of high-rise buildings, it is necessary to establish a secondary water supply system for high-rise buildings with pressurized water pumps. The municipal water supply network and the secondary water supply system of high-rise buildings work together to meet the water supply needs of high-rise buildings. In order to avoid ...
