Abstract

The invention discloses a double-door same-direction flow limiting valve. The valve comprises a floating barrel, a connecting rod, a double-door water blocking plate, a brake plate, a box body, a rotating shaft and a sealing rubber ring; the brake plate is fixed to one side of the box body, a water outlet is formed in the middle portion of the brake plate, the sealing rubber ring is arranged around the water outlet, the rotating shaft is located above the water outlet, and the floating barrel and the double-door water blocking plate are hinged to the rotating shaft; and buoyancy is used for driving the floating barrel to move upwards, and therefore the double-door water blocking plate is driven to be closed, preliminary rainwater flow limiting is achieved, and the flow limiting valve can be used for preliminary rainwater collection, rainwater sewage pipeline backward-flowing prevention and other municipal and water conservancy systems, external power and manual maintenance are not needed, and the valve is worth of popularization.

Description

technical field [0001] The invention relates to the field of drainage devices, in particular to a valve that uses a floating ball to drive a water baffle to realize flow limitation. Background technique [0002] Drainage system refers to the overall combination of drainage collection, transportation, water quality treatment and discharge and other facilities in a certain way. The general term for all levels of drainage ditches (pipes) and buildings used for waterlogging, waterlogging, and salt prevention. It is mainly composed of field drainage regulation network, drainage ditches at all levels, waterlogging lakes, drainage sluices, pumping and drainage pumping stations, and drainage capacity and discharge areas. flow, need to use flow limiting valve, but the previous flow limiting valves need maintenance, need external power and other deficiencies. Contents of the invention [0003] The present invention aims at the above-mentioned deficiencies of the prior art and prod...
