Description

technical field [0001] The invention relates to secondary water supply equipment, in particular to a novel hydrodynamic pressure control box-type superimposed pressure water supply equipment. Background technique [0002] Existing box-type water supply equipment, such as Figure 4 As shown, the box-type water supply equipment provided for "GB / T 37892-2019 Digital Integrated Full Frequency Conversion Control Constant Pressure Water Supply Equipment" has no steady flow tank plus vacuum suppressor and no negative pressure protection equipment. Adopt digital integrated full frequency conversion control technology, configure low-level water storage tanks, usually directly absorb water from the pressurized water supply pipe network, and ensure that the water pressure of the water supply pipe network is not lower than the set pressure value, so as to realize the superposition of the pipe network and the water supply of the water tank A complete set of water supply equipment that ca...

Problems solved by technology

[0011] Problems in the above technical solution: completely rely on the pressure sensor to switch and control the electric gate within the range of the set value of the pipe network pressure, and perform the conversion of superimposed water supply and normal pressure pressurized water supply to carry out mandatory protection of the pipe network

It cannot fundamentally guarantee the water supply safety of the water inlet pipe network, prevent and reduce the occurrence of low-pressure areas of the water inlet pipe network
