Abstract

The invention discloses a flange connected fluorine lined pneumatic V-shaped ball valve which comprises a ball valve body. A circulating channel I is arranged in the ball valve channel, a rotating cavity is formed in the circulating channel I, a rotatable V-shaped ball body is mounted in the rotating cavity, an upper rotating rod is arranged on the ball valve body, the lower end of the upper rotating rod is mounted on the upper part of the V-shaped ball body, a lower rotating rod is arranged on the ball valve body, a lower end cover is arranged on the lower end part of the lower rotating rod,a connecting part is arranged on the upper end part of the ball valve body, a supporting seat is mounted on the outer wall of the connecting part, a spring is mounted in the supporting seat, an upperend plate is fixed to the lower end of the spring, and a pneumatic executing part is mounted on the supporting seat. According to the flange connected fluorine lined pneumatic V-shaped ball valve provided by the invention, the supporting seat is arranged on the upper end part of the ball valve body to seal the ball valve body, so that the supporting seat, together with the pneumatic executing part, can rotate a certain angle, and the valve is sealed effectively. The flange connected fluorine lined pneumatic V-shaped ball valve is suitable for being used in a narrow space, and the mounting efficiency and the mounting difficulty of an integral pipeline are improved.

Description

technical field [0001] The invention relates to the field of pneumatic V-type ball valves, in particular to a flange-connected fluorine-lined pneumatic V-type ball valve. Background technique [0002] The V-type ball valve is a kind of ball valve. Its closing part is the valve plate. The valve plate is a hemisphere. There is a V-shaped opening on the hemisphere. During the turning process, the cross-sectional area of ​​the medium channel can be changed to form the adjustment of the medium flow. The applicant found the following problems in the installation process of the existing V-type ball valve: due to the large size of the pneumatic actuator part of the V-type ball valve, it is inconvenient to install in a narrow space, so the overall installation efficiency of the pipeline is low. Contents of the invention [0003] In view of this, the object of the present invention is to propose a flanged connection fluorine-lined pneumatic V-type ball valve to solve all or one of ...
