Description

Technical Field

[0001] The utility model relates to the technical field of sealed ball valves, in particular to a novel taper-matched hard-sealed ball valve. Background Art

[0002] Ball valves are used to control the on / off state of pipelines. There are generally two ways to connect ball valves: one is through a threaded connection with a sleeve, and the other is through a flange plate fitted and fixed with bolts. Both of the above connection methods require the addition of a sealing ring to improve the sealing performance.

[0003] When the pipeline needs to be frequently disassembled and assembled, the disassembly and assembly of the above two connection methods is relatively cumbersome, and the sealing rings are easily broken during the disassembly and assembly process, thereby affecting the sealing effect. Therefore, a ball valve that is easy to disassemble and assemble and has a more stable sealing fit is needed. Utility Model Content

[0035] In this embodiment, the ball 11 is rotatably installed in the ball groove corresponding to the valve body 1. A through hole is provided on the ball 11 to connect the tube body 14 on both sides of the valve body 1. The valve body 1 is provided with a valve sleeve 15 corresponding to the valve stem 12.
