The invention relates to the technical field of
energy conservation and
environmental protection, and discloses an energy-saving environment-friendly concealed regulating fire hydrant. The energy-saving environment-friendly concealed regulating fire hydrant comprises a concealed tank, wherein a water inlet
pipe is fixedly connected to the surface of the concealed tank; a
water storage tank is fixedly connected to the interior of the concealed tank; a pressurizing
pipe is movably connected to the interior of the
water storage tank; a return spring sleeves the surface of the pressurizing
pipe; apiston is movably connected to one end, away from the pressurizing pipe, of the return spring; and a
piston rod is fixedly connected to one end, away from the return spring, of the
piston. Accordingto the energy-saving environment-friendly concealed regulating fire hydrant, a retaining block on the surface of the
piston rod can move upwards along with the
piston rod; when the retaining block isin contact with a push plate, the retaining block can push the push plate to slide upwards on the surface of a sliding rail to make a connecting port gradually extends out of the ground surface; whenthe retaining block is in contact with the push plate, the piston does not move any more, the
water pressure in the
water storage tank increases, then water flows into a drain pipe in the piston fromthe pressurizing pipe, and a connecting port is lifted to complete discharging, so that the effect of guaranteeing the
water supply pressure while reducing the
valve opening pressure is achieved.
