Pipe network pressure-superposed steady-flow water supply equipment with adjusting water tank and auxiliary compensation pump

Abstract

The invention discloses pipe network pressure-superposed steady-flow water supply equipment with an adjusting water tank and an auxiliary compensation pump. The pipe network pressure-superposed steady-flow water supply equipment mainly comprises a back flow preventer, the stainless steel adjusting water tank, a steady-flow tank, the auxiliary compensation pump, a water disinfector, water supply pumps, a flow detection device, a pneumatic water tank and a control cabinet, wherein the stainless steel adjusting water tank and the steady-flow tank are connected in parallel and arranged in front of the water supply pumps; a water tank water outlet pipe of the stainless steel adjusting water tank is connected with a water outlet pipe of the steady-flow tank; the auxiliary compensation pump and a check valve II are mounted on the water tank water outlet pipe; and a solenoid valve II is mounted on the water outlet pipe of the steady-flow tank. The pipe network pressure-superposed steady-flow water supply equipment has the benefits that the stainless steel adjusting water tank and the steady-flow tank, which are connected in parallel, are switched for providing water sources for the water supply pumps for water supply, so that not only is the adjusted water quantity increased and the water supply security improved, but also the advantages of saving energy, being sanitary and the like of pipe network pressure-superposed water supply are achieved, the pressure is steady, the intelligent control can take an unattended operation effect, and therefore, a broad application prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of secondary water supply, in particular to a pipe network superimposed pressure stable flow water supply equipment provided with a regulating water tank and a compensating auxiliary pump. Background technique [0002] Pipe network superimposed water supply is a pressurized water supply that uses water pumps to be directly connected in series in the urban tap water pipe network. When the tap water inlet pressure is lower than the automatic pump stop pressure, the water pump stops. Due to the superimposed water supply of the pipe network, there is no adjustment of the water volume or adjustment of the water volume. Very limited, low-pressure stop of the pump often occurs, leading to unstable water supply pressure, hot and cold water from the shower head, fluctuating volume of flushing water, and low-pressure stop of the pump violates the water company's regulations on low-pressure stop of the pump, so it is in...

[0002] Pipe network superimposed water supply is a pressurized water supply that uses water pumps to be directly connected in series in the urban tap water pipe network. When the tap water inlet pressure is lower than the automatic pump stop pressure, the water pump stops. Due to the superimposed water supply of the pipe network, there is no adjustment of the water volume or adjustment of the water volume. Very limited, low-pressure stop of the pump often occurs, leading to unstable water supply pressure, hot and cold water from the shower head, fluctuating volume of flushing water, and low-pressure stop of the pump violates the water company's regulations on low-pressure stop of the pump, so it is in the pipeline network It is very necessary to adopt measures such as increasing the adjustment volume, stabilizing the flow and stabilizing the pressure, and ensuring the water quality and sanitation in the stacked water supply equipment.
