Abstract

The invention relates to the technical field of ball valves, in particular to a V-shaped ball valve. The invention relates to a V-shaped ball valve, which comprises a valve body, a valve rod, a valve disc, a valve seat, a driving device, a spherical disc and a disassembly structure installed on the front side of the valve body. Through the disassembly and assembly structure, the spherical flap detachably installed with the valve flap can be disassembled on-line to dismantle the damaged spherical flap and install a new spherical flap, which effectively solves the need to stop the pipeline and disassemble the valve for maintenance after the sealing surface of the valve ball is worn, causing manpower , The problem of a large amount of waste of material resources.

Description

technical field [0001] The invention relates to the technical field of ball valves, in particular to a V-shaped ball valve. Background technique [0002] V-type ball valve is a valve widely used in oil pipeline, natural gas pipeline and chemical industry and other systems. When the existing V-shaped ball valve is in use, the ball sealing surface is easily worn and the sealing performance is poor. When the ball sealing surface is worn out, it is necessary to stop running the pipeline, disassemble the valve for maintenance, and replace the valve ball, resulting in a large waste of manpower and material resources. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned disadvantages and provide a V-shaped ball valve which can replace the spherical disc on-line. [0004] In order to achieve the above object, the technical solution of the present invention is: a V-type ball valve, including valve body, valve stem, valve disc, ...
