Non negative pressure water supply equipment
Non negative pressure water supply equipment is a secondary pressurized water supply equipment that is directly connected to the municipal water supply network by a pressurized water supply unit, and is connected in series with the residual pressure of the municipal water supply network to ensure that the pressure of the municipal water supply network is not less than the set protection pressure (the set pressure must be higher than the pressure demand of the direct supply area of the community, generally not less than 1.2Kg).
