Non-negative pressure secondary water supply device

Abstract

The invention provides a non-negative pressure secondary water supply device. The non-negative pressure secondary water supply device comprises a pressure supplementing box, a pressure stabilizing box and a dredging box, wherein a side column is fixed on the left surface of the outer part of the pressure supplementing box; a spring end plate is fixed at the left end of the side column; an upper return spring and a lower return spring are fixed at the upper end and the lower end of the right side surface of the spring end plate respectively; the right ends of the upper return spring and the lower return spring are fixedly connected with the left side surfaces of an upper revolving door and a lower revolving door respectively; the bottom end of the upper revolving door is connected with the upper part of an upper connecting half shaft; the top end of the lower revolving door is connected with the lower part of a lower connecting half shaft; the upper connecting half shaft and the lower connecting half shaft are arranged on the left surface of the outer part of the pressure supplementing box; and an upper square hole and a lower square hole are formed in the left side surface of the pressure supplementing box. According to the technical scheme disclosed by the invention, the technical problems that the intelligent pressure supplementing capability is not achieved, automatic adjustment of water flow pressure and dredging of equipment cannot be realized and the like in the prior art are effectively solved, and popularization and application are facilitated.

Description

technical field [0001] The invention relates to the technical field of water supply, in particular to a secondary water supply device without negative pressure. Background technique [0002] Non-negative pressure secondary water supply equipment refers to the form that units or individuals store and pressurize urban public water supply or self-built water supply, and then supply it to users or for their own use through pipelines. The secondary water supply is mainly established to compensate for the lack of pressure in the municipal water supply pipeline and to ensure the water consumption of the people who live and live in high-rise buildings. Whether the secondary water supply facilities are built in accordance with the regulations, the quality of design and construction is directly related to the water quality, water pressure and water supply safety of the secondary water supply, and is closely related to the normal and stable life of the people. Compared with the raw wat...
