Problems solved by technology

In the process of opening and closing the gate, the water seal rubs against the gate pier and the steel plate to increase the resistance, so the opening and closing capacity needs to be increased, and the equipment investment is increased; the water seal rubs against the gate pier and the steel plate during the gate opening and closing process, and even rolls over And damage, reduce the service life, make the gate leak

Embodiment 1

[0017] Fig. 1 has provided present embodiment 1 figure, referring to Fig. 1, working head 1 adopts hardness (Shore, A type) to be 75 ± 5, elongation at break (%) >= 300, tensile strength (MPa) >= 20's of natural rubber. The working surface 2 of the water stop area on it is an inclined surface, the angle between it and the horizontal plane is α=20°, and the working head 1 is covered with a polytetrafluoroethylene outer bag F 4 Coating 3, there are three layers (also can be one or two or more layers) high-strength nylon canvas layer 4 in it, and the double wing 6 in the connecting wing plate 5 that is positioned at working head bottom and is connected with it adopts hardness (Shore, A Type) is 45 ± 5, elongation at break (%) ≥ 600, tensile strength (MPa) is made of natural rubber of 20. The wing heads 7 on the wings 6 are made of natural rubber with a hardness (Shore, Type A) of 65±5, an elongation at break (%)≥400, and a tensile strength (MPa)≥22.

Embodiment 2

[0019] Fig. 2 has provided the figure of embodiment 2 of the present invention.

[0020] Embodiment 2 is basically the same as Embodiment 1, except that the working surface on the working head is an arc surface.

Abstract

The invention provides a mixed material deformation water seal which is equipped with single wing and two ends. It includes work head which consists of the sealing area working surface, conjunction flange plate containing two swings which is on the lower of work head and connected with work head, the two swings are equipped with wing flutters respectively. The water seal is made of two rubbers at least which hardness, extensibility and elastic modulus are different. The water seal of invention has long service life, the sealing and leakage effect of anchor gate is fine.

Description

Technical field: [0001] The present invention relates to a high-pressure gate water seal, in particular to a double-wing single-head mixed-material hydraulically deformable water seal for high-water-head gates in hydropower stations, such as extra-large, large and medium-sized high-dam hydropower stations in my country. Background technique: [0002] The water seals of hydraulic gates are severely worn and torn during the opening and closing process of the gates, resulting in a large loss of energy due to water seal failure, and even endangering the safety of hydraulic structures. At present, most of the water seals used in my country's gate water-stop projects are P-type water seals. When it works, the water-stop surface on it contacts the steel plate installed first on the outer pier of the gate, compresses the cavity, and fills the gap between the water seal and the steel plate. water. In the process of opening and closing the gate, the water seal rubs against the gate pi...
