Water filling valves with four-direction-operation arc doors

Abstract

The invention discloses water filling valves with four-direction-operation arc doors. The arc door water filling valves are installed in top beam grids of gates, one water filling valve is installed on the portion, under a hanging shaft, of each gate, and each water filling valve and the corresponding hanging shaft are located in a vertical plane; each water filling valve comprises a water fillingpipe, an E-shaped water seal and the four-direction-operation arc door, the front and rear end faces of the water filling pipes are welded to gate panels and water seal bases respectively, the E-shaped water seals are installed in grooves of the water seal bases, and the two sides of each E-shaped water seal are fixed to the water seal bases through water seal press plates and bolts; the four-direction-operation arc doors are distributed at the tail ends of the water filling pipes, arc door panels of the four-direction-operation arc doors are tightly attached to the E-shaped water seals through mechanical compression for water retaining, two fixed pulleys are installed on horizontal partition plates of the top beams of the gates, the end, wound with a pull rope, on each fixed pulley is connected with a hanging shaft moving in a kidney-shaped hole in the corresponding gate, the other end, wound with a pull rope, on each fixed pulley is connected with the corresponding four-direction-operation arc door, and the four-direction-operation arc doors are further connected with balancing weights through pull rods. The water filling valves with the four-direction-operation arc doors can adapt to the conditions of water levels of different reservoirs and the sizes of the gates and are not influenced by silt, and water retaining is reliable.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to an arc-gate water filling valve operating in four directions. Background technique [0002] The emergency gates and overhaul gates in my country's hydropower projects are generally opened in still water, and water pressure needs to be filled behind the gate before opening the gate. At present, there are mainly the following types of gate water filling and pressure methods used in China: bypass valve type, water filling valve on the door, small opening lift gate, water filling between gate nodes, etc. Various flat pressure methods include: Its different characteristics and applicable conditions. [0003] 1. Bypass valve water filling: The bypass valve is set in the dam body or in the gate pier of the intake gate. The reservoir water in front of the gate flows to the back of the gate through the bypass valve. The water flow is controlled by the...

Problems solved by technology

[0005] In order to solve the problem that the traditional water filling valve will be stuck due to the influence of sediment, dirt and aquatic organisms and cannot work normally, the purpose of this invention is to provide a valve that can adapt to different reservoir water levels and gate sizes. Affected by sediment, reliable water stop, less maintenance, economical and practical four-way arc door water filling valve
