Specifically, the constant pressure water supply device 8 includes a first horizontal pipe 81 and a second horizontal pipe 84, the top of the side wall of the first horizontal pipe 81 is connected with the bottom end of the tank 91 through a water pipe, the bottom of the side wall of the first horizontal pipe 81 is fixedly provided with one end of a connecting pipe 82, the number of the connecting pipes 82 is three, the other ends of the three connecting pipes 82 are fixedly arranged on the side wall of the second horizontal pipe 84, and a water pump 83 is arranged on the side wall of the connecting pipe 82.

The negative pressure suppressor 6 is installed on the top of the flow regulator 9, is mainly used for protecting municipal pipe network from generating vacuum, and mainly comprises A, B, C and three cavities, when the water level of the flow regulator 9 is low, under the condition that the floating ball 66 (material: 06Cr19Ni10) is not contacted with the lip-shaped sealing ring 64, when the water inlet flow of the flow regulator 9 is larger than the water using flow, the water level gradually rises, the gas on the liquid level passes through the constant pressure cavity draft tube 612, the lip-shaped sealing ring 64, the gas enters the C cavity, the air filtering membrane 69 (material: polysulfone), and then passes through the low pressure cavity draft tube 610 and enters the low pressure cavity 94. When the water level rises to a certain height, the floating ball 66 rises to contact with the lip-shaped sealing ring 64, and reliable sealing is formed under the action of buoyancy (only 0.03 MPa). Along with the rise of the water level in the flow regulator 9, the water pump 83 starts to be laminated and run in an energy-saving mode, the high-pressure cavity 92 stores energy through the water outlet of the water pump 83, and the high-pressure cavity 92 reaches outlet pressure. When the water inflow is less than the water outflow and the water inflow pressure decreases, the water in the low pressure chamber 94 enters the chamber C through the low pressure chamber draft tube 610 and the air filter membrane 69 (made of polysulfone), and then enters the chamber B through the lip seal ring 64 and the constant pressure chamber draft tube 612 for transient regulation. When the inlet pressure sensor detects that the inlet pressure is reduced to the upper limit of the municipal minimum service pressure, water in the high-pressure cavity 92 enters the cavity B through the high-pressure cavity guide pipe 611 and the normally closed solenoid valve 62 (which is opened through control of the control cabinet) to be temporarily regulated, and when the inlet pressure sensor detects that the inlet pressure is reduced to the lower limit of the municipal minimum service pressure, the normally closed solenoid valve 62 is closed (which is controlled through the control cabinet). When the water level in the constant pressure cavity 93 drops, the floating ball 66 falls down, the gas enters the cavity B through the low pressure cavity draft tube 610, the air filtering membrane 69 and the lip-shaped sealing ring 64, and then enters the flow regulator 9 through the constant pressure cavity draft tube 612, and the gas is supplemented into the flow regulator 9, so that the flow regulator 9 is prevented from being vacuumized.

The device directly takes water from a municipal pipe network, tap water enters a constant pressure cavity 93 through a tap water pipe 1, a filter 3, a low-resistance backflow preventer 4, along with the entering of water, gas in the constant pressure cavity 93 is compressed to a low pressure cavity 94 through a negative pressure suppressor 6, after the constant pressure cavity 93 is full of water, the negative pressure suppressor 6 is automatically closed, the constant pressure cavity 93 and the low pressure cavity 94 are in a fully closed structure and are not contacted with the outside air, after the constant pressure cavity 93 is filled with water, when the inlet pressure sensor detects that the inlet pressure is higher than the protection pressure, the equipment starts the system to automatically run, after the equipment runs, the system detects the water pressure through an outlet pressure sensor of the equipment, compares the detected value with a set value, automatically controls the number and the operating frequency of the water pumps 83, adjusts the operating rotating speed of the water pumps 83 to realize the constant-pressure and constant-flow water supply of the system, and ensures the original pressure of the municipal pipe network to the maximum degree.
