Underground reduced pressure water supply system
The invention discloses an underground reduced pressure water supply system which comprises a plurality of reduced pressure water tanks, wherein each reduced pressure water tank comprises a tank body and a ball float valve; a water inlet reducing valve and a water outlet are arranged on the tank body; the ball float valve comprises a valve body, a drain pipe, a valve element, a lever and a float ball; the valve body is provided with an upper water cavity, a middle water cavity and a lower water cavity, and has an upper liquid inlet hole, a lower liquid inlet hole and a liquid outlet, and the liquid inlet hole is communicated with the water inlet reducing valve; the drain pipe is communicated with the upper water cavity and the lower water cavity; the valve element moves between a position closing the upper liquid inlet hole and the lower liquid inlet hole, and a position opening the upper liquid inlet hole and the lower liquid inlet hole; a hinge node on the lever is hinged on the tank body, and a node of the valve element is connected with the valve element; the float ball is connected on a float ball node of the lever, and the water outlet of one of two adjacent reduced pressure water tanks is connected with the water inlet reducing valve of the other one of the two adjacent reduced pressure water tanks. According to the underground reduced pressure water supply system provided by the embodiment of the invention, the static pressure of the system can be reduced, the feasibility is high, the reliability is strong, and the system is suitable for extradeep underground water supply.
