Abstract
The utility model discloses a water filling and pressure balancing device used for a plane gate. The water filling and pressure balancing device used for the plane gate comprises a retaining dam (1). The retaining dam (1) is provided with a water releasing or sand removing hole (2). The plane gate (3) is arranged on the inlet of the water releasing or sand removing hole, and a radial gate (4) is arranged on the outlet of the water releasing or sand removing hole. A water diversion steel tube (5) is arranged in the retaining dam. The inlet of the water diversion steel tube is slightly lower than the dead water level of the retaining dam, and the outlet of the water diversion steel tube is formed in the side wall, between the plane gate and the radial gate, on the top of the water releasing or sand removing hole. According to the water diversion steel tube, the technical problem that a gate top water filling valve cannot be closed due to the fact that the water releasing hole with high water head, high flowing speed and much sewage and without a sewage blocking device is blocked by the sewage after the plane gate is closed or water filling and pressure balancing cannot be carried out on the plane gate of the sand removing hole due to the fact that silt blocks a filling valve tube can be solved. A water releasing steel tube on the outlet of the water diversion steel tube is of a symmetrical and divergent structure and can reduce destruction to a water releasing or sand removing flow channel by the water flow. The water filling and pressure balancing device used for the plane gate has the advantages of being safe and reliable.
