The invention discloses a non-negative pressure water supply device capable of adjusting flow. The non-negative pressure water supply device comprises a base, the upper side wall of the base is connected with a flow-stabilizing compensating tank through a support, the side wall of the flow-stabilizing compensating tank is connected with a vacuum suppressor, the side wall of the flow-stabilizing compensating tank is provided with a pressure meter, the upper side wall of the base is further connected with a frequency conversion control cabinet through the support, the side wall of the flow-stabilizing compensating tank is further provided with a water inlet and a water outlet pipe, the water outlet pipe is provided with a fixed block which is internally provided with a spherical rotating groove, the side walls of the two sides of the fixed block are further provided with through holes communicating with the spherical rotating groove, a spherical rotating block is rotatably connected in the spherical rotating groove, a plurality of water flowing channels with different diameters are positioned in the spherical rotating block, and the fixed block is internally further provided with a rotating cavity communicating with the spherical rotating groove. The non-negative pressure water supply device is simple in structure and convenient to operate, the water outlet flow can be adjusted as required, and the non-negative pressure water supply device facilities use by users and can avoid waste of water resources.
Description
technical field [0001] The invention relates to water supply equipment, in particular to a non-negative pressure water supply equipment with adjustable flow. Background technique [0002] Generally speaking, in the traditional water supply mode, the tap water is first transferred from the municipal water plant, and then put into the water tank from the pipe network, and the water is supplied to the user through the booster pump. The water pressure on the municipal pipe network is completely wasted, and if the water pump is directly connected to the municipal pipe network to take water, it is easy to generate negative pressure and affect the water use of other surrounding users. Therefore, it is often necessary to supply water through non-negative pressure frequency conversion water supply equipment; but the existing The non-negative pressure frequency conversion water supply equipment in the technology is inconvenient to adjust the size of the water flow when the water is di...
