Abstract

The invention relates to the technical field of water conservancy engineering, and discloses a large-scale gate seal, which includes a casing, a rubber plate is fixedly connected to the top of the casing, a mounting seat is fixedly connected to the top of the rubber plate, and a hydraulic pressure is fixedly installed in the middle of the upper surface of the mounting seat. Cylinder, the output end of the hydraulic cylinder is fixedly connected with a hydraulic rod, the bottom of the hydraulic rod is fixedly connected with a connecting block inside the shell, both sides of the inner cavity of the shell are fixed with chute, and the bottom end of the chute is fixedly connected with a seal Pad, the inner cavity of the chute is fixedly connected with a seal. The large-scale gate seal, by setting the hydraulic cylinder, hydraulic rod, gate, seal and chute, uses the hydraulic cylinder to drive the gate at the bottom of the hydraulic rod to move up and down inside the chute to realize the opening and closing of the gate. The rubber sealing part arranged inside can effectively improve the sealing performance between the gate and the chute, achieve the purpose of good sealing effect of the large gate, and ensure the practicability of the large gate sealing part.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a large gate seal. Background technique [0002] The gate is used to close and open the control facility of the discharge channel. It is an important part of the hydraulic structure. It can be used to intercept the water flow, control the water level, adjust the flow, discharge sediment and floating objects, etc. When selecting the gate form, it needs to be based on the gate. The nature of work, setting position, operating conditions, gate opening span, opening and closing force and project cost, etc., combined with the characteristics of the gate, referring to the existing practical experience in operation, are determined through technical and economic comparisons, among which plane gates and arc gates are the most commonly used door shape. At present, the large-scale gate seals on the market have the phenomenon of flow leakage. Once the liquid often leaks...
