Abstract

The invention particularly relates to a two-way hard sealing semi-ball valve which comprises a valve body, a valve cover, a ball body, a two-way hard sealing structure and a driving device, wherein the valve body is arranged on one side of the two-way hard sealing semi-ball valve; the valve cover and the ball body are arranged on the other side of the two-way hard sealing semi-ball valve, and the ball body is arranged in a cavity formed by the valve body and the valve cover; the two-way hard sealing structure is arranged between the ball body and the valve body; the two-way hard sealing semi-ball valve is sealed; and the driving device is used for rotating the ball body to open and close the two-way hard sealing semi-ball valve. The ball body is arranged in the cavity formed by the valve body and the valve cover, the two-way hard sealing structure is arranged between the ball body and the valve body, and the two-way hard sealing semi-ball valve is sealed, so that two-way sealing of the valve is achieved, and the technical problem that in the prior art, an inlet end of a common hard sealing semi-ball valve is sealed in a one-way mode, and an outlet end is not sealed in the reverse direction is solved.

Description

technical field [0001] The embodiment of the present invention relates to a ball valve, in particular to a two-way hard-sealed hemispherical valve. Background technique [0002] In the prior art, the general hard-sealed hemispherical valve is sealed at the one-way inlet end, and the outlet end is not sealed at the opposite direction; when sealing different media, due to the one-way seal, it will cause mixing between the media. Seriously, it will cause an accident. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a bidirectional sealing ball valve capable of realizing bidirectional sealing. [0004] In order to achieve the above object, the embodiment of the present invention designs a two-way hard-sealed hemispherical valve, which is characterized in that it includes: [0005] A valve body, the valve body is arranged on one side of the two-way hard-sealed hemispherical valve; [0006] A valve cover, the valve cover...
