Description

Multipurpose non-negative pressure water supply system

Technical Field

The invention relates to the technical field of non-negative pressure water supply, in particular to a multipurpose non-negative pressure water supply system.

Background

Running water enters the flow stabilizing tank, and the air in the flow stabilizing tank is discharged from the vacuum cleaner. After the water is full. The vacuum eliminator is automatically turned off. When the pressure of the tap water pipe network can not meet the water consumption requirement, the system alcohol over-pressure sensor (or a pressure controller, an electric contact pressure gauge) gives a pump starting signal to start the water pump to run. When the water pump is used, if the water quantity of the tap water pipe network is greater than the water accumulation flow, the system can normally supply water, and when the water consumption peak is reached, if the water quantity of the tap water pipe network is less than the water pump flow, the water in the regulating tank can still be normally used as a supplementary water source. Air enters the round-node tank through the vacuum eliminator, and the negative pressure of the tap water pipe network is eliminated. After the peak period of water consumption, the system recovers to a normal state;

however, when the non-negative pressure water supply system in the prior art supplies water in winter, the interior of the system is easy to freeze, so that water flow cannot flow.
