Description

technical field [0001] The invention belongs to the technical field of intelligent water supply, and in particular relates to a non-negative pressure water supply device capable of intelligently adjusting the water supply flow of high, medium and low peaks. Background technique [0002] The non-negative pressure water supply device is a pressurized device directly connected to the water supply network. The traditional water supply method is inseparable from the reservoir. The water in the reservoir is generally supplied by the tap water, so that the water under pressure becomes zero after entering the pool, resulting in a large amount of energy wasted, and the non-negative pressure water supply equipment is a It is an ideal energy-saving water supply equipment. It is a secondary water supply equipment that can be directly connected to the tap water pipe network and will not have any side effects on the tap water pipe network. On the basis of the pressure of the municipal p...

Problems solved by technology

The traditional water supply method is inseparable from the cistern. The water in the cistern is generally supplied by the tap water pipe. In this way, the pressured water becomes zero after entering the pool, resulting in a lot of waste of energy. The non-negative pressure water supply equipment is a It is an ideal energy-saving water supply equipment. It is a secondary water supply equipment that can be directly connected to the tap water pipe network without any side effects on the tap water pipe network. It directly superimposes water supply on the basis of the pressure of the municipal pipe network to save energy.

[0003] However, the traditional non-negative pressure water supply device only has the function of secondary pressurization. When the demand for water is small, the flow rate is too fast, resulting in waste of energy. Using intelligent adjustment of high, medium and low peaks, there are many inconveniences in use and management
