High-rise non-negative-pressure energy-saving water supply system

Abstract

The invention discloses a high-rise non-negative-pressure energy-saving water supply system. The high-rise non-negative-pressure energy-saving water supply system comprises a water inlet main pipe, a water inlet branch pipe, a return pipe, flow control devices, measuring devices, a water inlet main pipe, non-return devices and a control device, wherein the water inlet main pipe is connected with the water inlet branch pipe, and the tail end of the water inlet branch pipe is connected with a water outlet pipe through the control device; the return pipe is connected between the water outlet pipe and the water inlet branch pipe; the flow control devices are arranged on the water inlet branch pipe and the return pipe respectively; the measuring devices are arranged on the water inlet branch pipe and the water outlet pipe respectively; the water inlet main pipe is connected with the water outlet pipe; the non-return devices are arranged on the water inlet main pipe and the water inlet branch pipe respectively; and the control device is electrically connected with the measuring devices and the flow control devices respectively and can control the flow control devices and water outlet according to measured data of the measuring devices. The water supply system can provide stable water flow when the water flow pressure reaches the standard in the peak period, can perform very detailed statistics and data output on water supply pressure data, can prevent negative pressure from being generated on a water supply pipe network, can effectively control the water supply flow, is convenient to adjust and can intelligently control the water flow and pressure, and then energy-saving water supply is achieved.

Description

technical field [0001] The invention relates to the field of water supply, in particular to a non-negative pressure energy-saving water supply system for high-rise buildings. 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 o...

Problems solved by technology

However, the existing high-rise non-negative pressure water supply system has certain shortcomings: first, the existing high-rise water supply system stores a certain amount of water in advance by setting up a buffer tank, but this method is prone to pollution problems in the water source tank, because the water source The water tank not only has an overflow port, but also is not completely sealed. In addition, the water source tank must be cleaned regularly to avoid water quality deterioration, resulting in waste of water resources; pressure, and then use the pressurized water pump of the secondary water supply system to suck the water in the water source water tank and pressurize it, which causes a serious waste of water supply pressure energy in the municipal water supply network with a certain pressure; thirdly, in order to consider the peak of high buildings For water use, it is necessary to build a larger volume water source tank, which increases the construction cost of the high-rise secondary water supply system
