Abstract

The invention discloses a double-door different-direction flow-limiting valve which comprises float bowls, connecting rods, a double-door water-blocking plate, a gate plate, a tank, a rotating shaft and a sealing rubber ring. The gate plate is fixed to one side of the tank, a water outlet hole is formed in the middle of the gate plate and is surrounded by the sealing rubber ring, the rotating shaft is located above the water outlet hole, and the float bowls and the double-door water-blocking plate are hinged to the rotating shaft. The double-door different-direction flow-limiting valve utilizes a buoyancy force to drive the float bowls to move upwards so as to close the double-door water-blocking plate, initial rainwater flow limiting is achieved, and the double-door different-direction flow-limiting valve can be used for initial rainwater collection, storm sewage pipeline backward-flowing prevention and other municipal and water-conservancy systems, does not need external power and artificial maintenance and is worthy 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...
