Next, with reference to the drawings in the description, a fully automatic pressurization zone superimposed water supply equipment of the present utility model will be described in detail below.

A fully automatic pressurization zone superimposed pressure water supply equipment, its structure includes a steady flow compensator connected to the tap water inlet pipe through a filter and a backflow prevention device, and the steady flow compensator is connected to the pump through its own bottom water outlet and water distribution main pipe The pump group is divided into a low-zone pump group and a high-zone pump group, the low-zone pump group is connected to the low-zone microcomputer control cabinet and is controlled by it, and the high-zone pump group is connected to the high-zone microcomputer control cabinet and controlled by it. The pumps in the low area pump the water to the users in the low area through the water collection main in the low area; the pumps in the high area pump the water to the users in the high area through the water collection main in the high area. The water distribution main pipe is connected with the pump set in the low zone and the pump set in the high zone through a flexible joint and a valve is arranged there. The outlets of the pumps in the low zone and the pumps in the high zone pass through the noise-absorbing check valves, valves, and flexible joints to the water collection mains in the low area and the water collection mains in the high area to pressurize and pressurize and supply water at a constant pressure. The top of the steady flow compensator is equipped with a vacuum suppression device and a water stop protection device, and a sewage outlet is provided at the bottom. The water distribution main pipe is equipped with a pressure limiting protection device, an automatic pressure supplement device sensor and a pressure supplement pipe to monitor the pressure of the municipal pipe network and supplement the pressure of the municipal pipe network respectively. Pressure sensors for detecting and feeding back the user's pipe network pressure are installed on the low area water collection main pipe and the high area water collection main pipe. The pump in the low area is assembled with a bypass pipeline system for preventing water cutoff, and the municipal pipe network water can be supplied through the bypass pipe when the system stops water supply. A disinfection interface for disinfection or detection inside the system is provided on the water distribution main pipe.

For the initial operation, the minimum pressure limit of the local tap water pipe network is set as the pressure protection value and water cut-off protection pressure. If it is lower than the pressure protection value of 0.01-0.05MPa, it is set as the start value of automatic inspection and pressure supplementation, reaching the normal pressure value of the municipal pipe network. For the stop value, the air in the steady flow compensator is removed through the vacuum suppressor device, and the equipment is powered on in automatic operation. The microcomputer control system monitors in real time the inlet pressure of the tap water pipe network, the water supply pressure of the user pipe network, the pressure protection limit value, the automatic pressure supplement start-stop value, and the stop pressure value.
