  • Large-scale hydraulic variable-speed floating box flap valve
    Patent number: 9103452
    Abstract: A large-scale hydraulic variable-speed floating box flap valve includes a hinge support, a valve seat, an upper valve leaf and a lower valve leaf, the valve seat and the hinge support are both fixed on a pump station base. The upper valve leaf is hinge-connected to the hinge support through a pin shaft, and the lower valve leaf is hinge-connected to the upper valve leaf. The upper valve leaf and the lower valve leaf may contact and match the valve seat in a sealed manner through a sealing structure. The upper valve leaf is connected to the lower valve leaf through at least one hydraulic mechanism. The hydraulic mechanism has one end hinge-connected to the upper valve leaf, and the other end hinge-connected to the lower valve leaf. The impact force between the valve leaves and the valve seat is damped by the hydraulic mechanism.
