Current limiting type pipe network pressure-superposed water supply device
The invention discloses a current limiting type pipe network pressure-superposed water supply device. The current limiting type pipe network pressure-superposed water supply device mainly comprises a current stabilizing tank, a negative pressure canceller, a water pump, a current limiting check valve and a control cabinet, wherein the current stabilizing tank is connected with a tap water inlet pipe, water flowing out of the current stabilizing tank flows into a water outlet main pipe after passing through the current limiting check valve through the water pump, and the water outlet main pipe is connected with a user pipe network water supplying place to supply the water, and the current limiting check valve is installed on a water pump outlet, connected with a water pump inlet through a connection port, and used for limiting the water pump flow and stabilizing water pump pressure, enables the water pump to work in a high efficiency area, and prevents overload of the low lift and large flow water pump from burning out a motor. The current limiting type pipe network pressure-superposed water supply device can directly concatenate water supply to achieve non-negative pressure and energy saving water supply effects, and installs the current limiting check valve on the water pump outlet to effectively avoid reducing of the water pump lift and increasing of flow rate, prevents the overload of the water pump, and has current limiting, return stopping and water hammer eliminating functions. The current limiting type pipe network pressure-superposed water supply device is good in water supply safety, efficient in energy conservation, convenient to install and maintain, and small in land occupation.
