Embodiment Construction

[0009] Such as figure 1 , figure 2 As shown, the tank bottom ball valve provided by the first embodiment of the present invention includes a valve body 1, a ball 2 is arranged in the valve body 1, and a seal ring 3 is used to seal between the ball 2 and the inner cavity of the valve body, and the shape of the seal ring 3 is the same as that of the ball The outer surfaces of the two are matched, the inner surface of the sealing ring 3 wraps the outer surface of the sphere 2 , and the sealing ring 3 arranged at the outlet end and the inlet end of the valve jointly wraps all the outer surfaces of the sphere 2 .

[0010] Such as figure 2 As shown in the above embodiment, the inner surface of the sealing ring 3 is formed by the smooth transition of two curved surfaces with different radii. This hyperboloid structure design can not only ensure the sealing between the sphere 2 and the sealing ring 3, but also reduce the pressure of the sealing ring 3 and the sphere 2. The frictio...

Abstract

The invention discloses a tank bottom ball valve, which comprises a valve body. A sphere is arranged in the valve body; the sphere and the inner cavity of the valve body are sealed by a sealing ring; the shape of the sealing ring is matched with the outer surface of the sphere; the inner surface of the sealing ring covers the outer surface of the sphere; and the sealing rings which are arranged at an outlet end and an inlet end of the valve commonly cover all the outer surfaces of the sphere. The shape of the sealing ring of the tank bottom ball valve provided by the invention is matched with the outer surface of the sphere and the inner surface of the sealing ring covers the outer surface of the sphere. The global sealing ring structure closes off the space for a residual medium, eliminates the possibility of the existence of the residual medium, can completely drain the medium, and makes the valve and pipelines wash and disinfect easy.

Description

technical field [0001] The invention relates to a tank bottom ball valve. Background technique [0002] Traditional tank bottom ball valves generally have dead angles because the sealing ring does not completely cover the ball, and the dead angles are prone to residual media, which affects the sanitation and safe use of the media. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tank bottom ball valve without residual medium dead space. [0004] For this reason, the tank bottom ball valve provided by the present invention includes a valve body, a ball is arranged in the valve body, and a sealing ring is used to seal between the ball and the inner cavity of the valve body, the shape of the sealing ring matches the outer surface of the ball, and the inner surface of the sealing ring wraps the outside of the ball The surface, the sealing rings arranged at the outlet and inlet of the valve jointly wrap all the oute...
