Abstract
The utility model discloses a horizontal type pipe network overlying frequency conversion non-negative pressure water supply device. The horizontal type pipe network overlying frequency conversion non-negative pressure water supply device is characterized in that a water storage tank body (1) which is installed horizontally, two water outlet pipelines (2a, 2b) and a user water supply pipeline (3) are included, wherein a municipal pipe network access port (10) and a pressure gage (11) which is installed on the tank body are arranged at the upper portion of the water storage tank body. The two water outlet pipelines are connected with the water storage tank body through a three-way pipeline, and multistage centrifugal pumps (20) and control valves (21) are installed on the two water outlet pipelines. The user water supply pipeline is connected at the outlet positions of the two water outlet pipelines and is provided with a pressure meter (30). The horizontal type pipe network overlying frequency conversion non-negative pressure water supply device is simple in structure, lower in manufacturing cost and suitable for large-scale popularization and application.
