Background
The non-negative pressure water supply equipment is a pressurized water supply unit, is directly connected with a municipal water supply network, and is serially connected with a pressure-superposed water supply system 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 higher than the pressure requirement of a direct supply area of a community and is generally not less than 1.2 Kg). The core of the non-negative pressure water supply equipment is how to prevent negative pressure from generating in the operation process of the secondary pressurized water supply system, eliminate the influence of unit operation on the municipal pipe network, and realize safe, reliable, stable and water supply on the premise of ensuring that the water consumption of nearby users is not influenced. The existing non-negative pressure water supply equipment generally adopts a vacuum suppressor, tap water enters a steady flow tank, air in the tank is discharged from the vacuum suppressor, the vacuum suppressor can be automatically closed after the steady flow tank is full of water, when negative pressure is formed in the steady flow tank, an air inlet valve of the vacuum suppressor is opened, the atmosphere enters the steady flow tank, and the negative pressure is eliminated. The existing mode still has the condition of unstable water flow.
