Pipe network differential pressure compensation no-negative-pressure pressure-superposed water supply equipment
The invention discloses pipe network differential pressure compensation no-negative-pressure pressure-superposed water supply equipment. The pipe network differential pressure compensation no-negative-pressure pressure-superposed water supply equipment mainly comprises a steady-flow compensation tank, a negative-pressure eliminator, a flow control valve, a compensation pump, a water supply pump and a control cabinet, wherein the steady-flow compensation tank adopts a dual-cavity horizontal structure consisting of a water storage cavity and a steady-flow cavity; a water inlet I is formed in the top of the water storage cavity, and a water outlet I is formed in the bottom of the water storage cavity; the water inlet I is connected with a tap water inlet pipe through a connecting pipe; and the water outlet I is communicated with a water distribution pipe through a compensation pipe on which the compensation pump is mounted. The pipe network differential pressure compensation no-negative-pressure pressure-superposed water supply equipment has the benefits that as the steady-flow compensation tank adopts the dual-cavity structure integrating the steady-flow cavity and the water storage cavity, the advantages of compact structure, small occupied land, convenient management and maintenance, energy saving, good sanitariness, stable pressure and the like are achieved; the flow control valve is arranged to limit the pressure drop of the tap water inlet pipe and guarantee no-negative-pressure tandem water supply; and the water storage cavity and the compensation pump can perform differential compensation and adjustment on tap water inflow deficiency, so that the adjustment volume is increased and the water supply security is improved.
