Description

technical field

[0001] The invention relates to the technical field of automatic water supply, in particular to a pressure-stabilized non-negative pressure water supply system. Background technique

[0002] The non-negative pressure water supply is a pressurized water supply unit, which is directly connected to the municipal water supply network, and the water supply is superimposed in series on the basis of the residual pressure of the municipal pipe network to ensure that the pressure of the municipal pipe network is not less than the set protection pressure (the set pressure must be high According to the pressure demand of the direct supply area of ​​the community, generally not less than 1.2Kg) the secondary pressurized water supply equipment, the core of the pipe network superimposed pressure (no negative pressure) water supply equipment is how to prevent negative pressure during the operation of the secondary pressurized water supply system Pressure generation, elimina...
