Introduction of non-negative pressure water supply equipment

The non-negative pressure water supply equipment is a pressurized water supply unit directly connected to the municipal water supply pipe network, and series superimposed water supply based on 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 (which can be a relative pressure 0 pressure, less than 0 pressure is called negative pressure) secondary pressurized water supply equipment. The core of the pipe network superimposed (no negative pressure) water supply equipment is how to prevent negative pressure during the operation of the secondary pressurized water supply system, eliminate the impact of unit operation on the municipal pipe network, and ensure that it does not affect the water use of nearby users Realize safe, reliable, stable and continuous water supply. Non-negative pressure water supply equipment is also called pipe network superimposed water supply equipment. At present, there are mainly tank-type non-negative pressure water supply equipment and box-type non-negative pressure water supply equipment on the market.u003c/pu003e
