Abstract

The invention provides non-negative-pressure water supply equipment and a water supply method. The non-negative-pressure water supply equipment comprises a water inlet pipe, a flow stabilizing tank, an outflow pipe, a water pump water inlet header pipe, a frequency conversion unit, a water pump water outlet header pipe and a water supply pipe which are sequentially connected. A water inlet branch pipe is further connected between the water inlet pipe and the water pump water inlet header pipe, and a first electromagnetic valve is arranged on the water inlet branch pipe; a second electromagnetic valve is arranged on the outflow pipe; the system further comprises a large-volume small-flow high-pressure tank, and a first energy storage device is arranged in the large-volume small-flow high-pressure tank. A water inlet pipe and a water outlet pipe are connected between the water supply pipe and the large-volume small-flow high-pressure tank, a pressure reducing valve and a flow adjusting valve are arranged on the water outlet pipe, and a booster pump, a first check valve and a first butterfly valve are arranged on the water inlet pipe. According to the non-negative-pressure water supply equipment and the water supply method, water can be continuously supplied to a user pipe network, and the water supply quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of municipal water supply, and in particular relates to a non-negative pressure water supply equipment and a water supply method. Background technique [0002] Secondary pressurized water supply equipment is increasingly used in high-rise water supply. Non-negative pressure water supply equipment basically adopts the structure of a steady flow tank alone, and the municipal water supply, the steady flow tank and the pump are in series mode for pressurized water supply. When the water consumption peaks, the municipal water consumption is less than the user's water consumption, the water flow may not meet the user's demand, and the water stored in the steady flow tank may not meet the user's demand. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a non-negative pressure water supply device and a water supply method, which can continuously supply wate...
