Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the disadvantages of the prior art that the core hardness of the ball valve is low, the wear resistance is poor, and relies on lubricant lubrication, thereby providing a ball valve with high hardness and good wear resistance, And the ball core on the surface of the low-temperature hard aluminum oxide film can be used normally without lubricant, thus avoiding the problem of shortening the service life of the ball core in the ball valve due to the failure of the lubricating oil

Abstract

The present invention provides a spherical aluminum valve core, a ball valve, and a manufacturing process for a spherical aluminum valve core, wherein the spherical aluminum valve core includes an aluminum valve core body, the valve core body is spherical, and is provided with a flow channel communicating with a pipeline and The connection structure used for connecting the valve stem, the outer periphery of the valve core body is provided with an aluminum oxide film layer. The spherical aluminum valve core on the alumina surface has the advantages of high hardness, smooth wear resistance, and no rust. It does not need to add lubricant during installation, thereby avoiding the problem of shortening the service life of the ball core in the ball valve due to the failure of the lubricating oil. In the prior art, the ball core of the ball valve has low hardness, poor wear resistance, and relies on lubricants for lubrication.

Description

technical field [0001] The invention relates to the field of ball valve design, in particular to a spherical aluminum valve core. The invention also provides various types of ball valves and a manufacturing process for the spherical aluminum valve core. Background technique [0002] The ball valve is a commonly used valve. The ball core is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small rotational torque to close tightly. [0003] The ball cores used in traditional ball valves are mostly copper-plated decorative chromium, which has the following defects: low hardness, poor wear resistance, and the surface of the ball core and the sealing ring are lubricated by lubricating oil. Will fail, turn the ball core when switching the ball valve aft...
