Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, a sealing gasket for a ball valve comprises a ball valve body 1, a gasket body 8 and a fixing ring 7, wherein the fixing ring 7 is fixedly connected to two sides of the ball valve body 1, the gasket body 8 is movably connected to the fixing ring 7, the gasket body 8 is movably connected with the ball valve body 1, and one side of the gasket body 8, which is far away from the ball valve body 1, is provided with a valve seat 4.

Specifically, the gasket main body 8 is movably connected with the valve seat 4, a plurality of movable grooves 9 are formed in the valve seat 4, and support columns 11 are arranged in the movable grooves 9.

Through above-mentioned technical scheme, support column 11 keeps away from gasket main part 8 one end and disk seat 4 laminating.

Specifically, support column 11 and gasket main part 8 fixed connection, flexible subassembly 10 is connected with on the support column 11.

Through above-mentioned technical scheme, the elastic component 10 promotes the gasket main part 8 through self elasticity for gasket main part 8 and ball valve main part 1 laminate more.

Specifically, two sealing rings 3 are fixedly connected to one side, away from the movable groove 9, of the valve seat 4, and a double-end flange 5 is movably connected to the valve seat 4.

Through above-mentioned technical scheme, sealing ring 3 is arranged in preventing water from entering into the gap between disk seat 4 and connecting block 2, and double-ended flange 5 is located disk seat 4 periphery and double-ended flange 5 and disk seat 4 closely laminating.
