Pipe network pressure-superposed fire hydrant water supply system
The invention discloses a pipe network pressure-superposed fire hydrant water supply system. The pipe network pressure-superposed fire hydrant water supply system is mainly composed of filters, backflow prevention devices, fire pumps, an air pressure water tank, a pressure controller, a control cabinet, a pressure maintaining valve, a water pump connection device, a fire hydrant and a high-position water tank pressure boosting and stabilizing device; the two to four fire pumps are arranged in parallel, inlet water of the fire pumps is connected with a water distribution header pipe, and a pressure detecting meter is installed on the water distribution header pipe and used for monitoring the inlet water pressure and protecting the fire pumps; and the two ends of the water distribution header pipe are connected with two ways of water inlet including a tap water pipe A and a tap water pipe B, when one way of water inlet breaks down, it is guaranteed that the other way of water inlet can still provide sufficient water sources, and the tap water pipe A and the tap water pipe B are each provided with a negative pressure meter, one filter and one backflow prevention device in the water flow direction in sequence. The pipe network pressure-superposed fire hydrant water supply system has the beneficial effects that the direct tandem pipe network pressure-superposed water supply mode is adopted, and fire fighting extinguishment safety and control are guaranteed; and the pipe network pressure-superposed fire hydrant water supply system has the advantages of being small in occupied land and convenient to install, saving investment and the like.
