The novel eccentric hemispherical valve has the advantages of being simple in structure, and convenient to install and maintain.

Description

The Novel eccentric semispherical valve

Technical field

The utility model relates to a kind of Novel eccentric semispherical valve.

Background technique

Though the soft seal eccentric half-ball valve can reach the effect of zero sealing in use on the existing market, its structure is comparatively complicated, and installation and maintenance are also comparatively loaded down with trivial details.

The model utility content

The purpose of this utility model is exactly in order to address the above problem, and a kind of Novel eccentric semispherical valve is provided.

To achieve these goals, the utility model adopts following technological scheme:

A kind of Novel eccentric semispherical valve comprises valve body (10), establishes hemisphere spool (11) in the described valve body, and this valve body has entry end and outlet end, and the bottom of described valve body and top arrange bearing support (12), it is characterized in that, also comprise:

One Upper shaft sleeve (13), it is located in the bearing support at valve body top, is positioned at this Upper shaft sleeve and establishes rotating upper semiaxis (14);

Semiaxis (15) once, it is located in the bearing support of valve body bottom, and this time semiaxis one end stretches in the valve body, and the external part of time semiaxis is rotatablely equipped with Lower shaft sleeve (16), wherein,

The described up and down corresponding end of semiaxis is provided with the hemisphere spool (11) on the runner between valve body entry end, the outlet end.

The beneficial effects of the utility model are: simple in structure, installation and maintenance are convenient.
