Description

Technical Field

[0001] The utility model belongs to the technical field of water supply, in particular to a secondary water supply device used in rooftops and buildings. Background Art

[0002] In the field of water supply, superimposed water supply, also known as "non-negative pressure water supply", is a modern water supply technology that directly utilizes the residual pressure of the outdoor water supply network and then superimposes additional pressure through equipment such as water pumps to achieve secondary water supply. This water supply method is particularly common in high-rise buildings, because the pressure of the municipal pipe network can usually only supply to the seventh or eighth floor, and the superimposed water supply technology can help provide water to higher floors where water pressure cannot reach naturally. The advantages of superimposed water supply include energy saving and hygiene, but due to its impact on the municipal pipe network, it may be slightly insufficient in flow regulation. In addition, superimposed water supply equipment is usually directly connected in series to the municipal tap water pipeline and works by differential compensation, that is, the pressure difference is compensated as much as possible. This design makes the pressure starting point of the equipment relatively high, so it is more energy-efficient than ordinary water supply equipment. At the same time, this water supply method also avoids secondary pollution of water quality because it belongs to a closed system.

[0003] The Chinese invention patent with publication number CN112012270A discloses an energy-saving silent superimposed water supply device for residential water supply, including a water inlet main pipe, a flow stabilization tank, a negative pressure eliminator, a silent pump assembly, and a control cabinet. The interior of the flow stabilization tank is divided into a water storage chamber located at the top and a buffer chamber located at the bottom. The buffer chamber and the water storage chamber are connected through a pressure relief pipe. The buffer chamber is provided with a pressure reducing buffer assembly connected to the bottom of the flow stabilization tank. The water storage chamber and the buffer chamber are respectively connected to the water distribution main pipe or the water outlet main pipe. The silent pump assembly is connected to the water distribution main pipe to pressurize the tap water and then distribute it to users at each distribution point through the water outlet main pipe.
