Description

Technical Field

[0001] The utility model specifically relates to the technical field of smart water services, and in particular is a negative pressure-free water supply device for smart water services. Background Art

[0002] The non-negative pressure water supply equipment uses the municipal pipe network as its water source, making full use of the original pressure of the municipal pipe network to form a closed continuous relay booster water supply method. It has good energy-saving effects and no secondary pollution of water quality. It is the development and extension of variable frequency constant pressure water supply equipment.

[0003] Chinese utility model publication number CN 215442167 U discloses a non-negative pressure water supply device. In order to reduce the use cost of the non-negative pressure water supply device, the utility model proposes a non-negative pressure water supply device, which includes a base, a pressure stabilizing tank, a constant pressure tank and a pump group, the pressure stabilizing tank is mounted on a support on the base, and a water outlet pipe is arranged at the bottom of the pressure stabilizing tank; the constant pressure tank is located above the pressure stabilizing tank and is connected to the pressure stabilizing tank; the pump group includes a plurality of water pumps, the water pumps are installed on the base and distributed on both sides of the pressure stabilizing tank, and the water inlet of the water pump is connected to the water outlet pipe;

[0004] The above-mentioned non-negative pressure water supply equipment ensures the stability of the water flow pressure inside by placing a constant pressure tank above the pressure-stabilizing tank. However, during long-term use, the water level in the water storage tank will drop. When the water level is low, insufficient water supply is likely to occur. For this reason, we provide a non-negative pressure water supply equipment for smart water services. The liquid level position is detected by a liquid level detector, thereby avoiding the situation where the ground is low. Secondly, the pressure relief valve can discharge excess gas to avoid damage and pressurization caused by excessive pressure, effectively compensating for the above-mentioned problems.
