Large-deformation water stop device and gate valve

Abstract

The invention provides a large-deformation water stop device and a gate valve, and relates to the technical field of the water conservancy project. The large-deformation water stop device comprises abracket, a flexible water stop part and a water stop embedded part, wherein the flexible water stop part is mounted on the bracket, and the bracket is connected to a gate; the water stop embedded partis opposite to the gate, and a gap is formed between the water stop embedded part and the gate; while the gate is in a closed state, the flexible water stop part is positioned between the gate and the water stop embedded part; the flexible water stop part comprises a first section and a second section which are connected to each other; the thickness of the first section is greater than that of the second section; a through hole is formed inside the first section in a length direction; the biggest thickness, in the radial direction of the gate, of the first section is 150mm-250mm; and the biggest distance between the flexible water stop part and the gate is greater than the smallest distance between the water stop embedded part and the gate. The large-deformation water stop device is applied to a gate system, and the water stop part in the large-deformation water stop device has relatively great compression amount, so that greater deformation of the gate can be adapted.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a large deformation water stop device and a gate system. Background technique [0002] In the field of water conservancy engineering, the water stop at the bottom of the rotary steel gate generally uses a water stop. The water stop is compressed and deformed between the gate and the bottom sill, so as to play the role of sealing and water stop. [0003] However, at present, the compression deformation of the water stop at the bottom of the gate is limited. If the deformation of the gate is large at the water stop, due to the small compression deformation of the water stop, the water stop will be separated from the bottom sill, resulting in water leakage. [0004] Therefore, the compression amount of the water stop member in the prior art is relatively small, and cannot meet the working requirements of large deformation of the gate.
