Abstract

The invention discloses non-negative pressure water supply equipment. The non-negative pressure water supply equipment comprises a flow stabilizing tank, a flow stabilizing tank water outlet pipe connected with the bottom of the flow stabilizing tank, a water pump connected with the flow stabilizing tank water outlet pipe and a water pump water outlet header pipe connected with the water pump, anda water inlet and a vacuum suppressor are arranged above the flow stabilizing tank; and a high-pressure cavity is formed in the upper portion of the flow stabilizing tank, and the high-pressure cavity is filled with harmless inert gas in advance. The double-vacuum-suppression function is adopted for further suppressing vacuum, equipment is more stable, mechanical fatigue caused by unstable waterpressure is prevented, the service life of the equipment is greatly prolonged, tap water stability is greatly improved, the whole control process is not in contact with air, and a municipal pipe network is safer and more environmentally friendly.

Description

technical field [0001] The invention relates to the field of water supply equipment, in particular to a non-negative pressure water supply equipment. Background technique [0002] The non-negative pressure water supply equipment is a pressurized water supply unit, which is directly connected to the municipal water supply pipe network, and is superimposed on the residual pressure of the municipal pipe network to supply water in series to ensure that the pressure of the municipal pipe network is not less than the set protection pressure (the set pressure must be Secondary pressurized water supply equipment that is higher than the pressure demand of the direct supply area of ​​the community, generally not less than 1.2Kg). The core of the non-negative pressure water supply equipment is how to prevent the generation of negative pressure during the operation of the secondary pressurized water supply system, eliminate the impact of unit operation on the municipal pipe network, and...
