An anti-expansion ball valve

Abstract

The invention discloses an anti-swelling ball valve and belongs to the field of ball valves. The anti-swelling ball valve can resist a pressure from a fluid effectively, so that the valve body is noteasily swelled. By matching with the action of a barb body, the anti-swelling ball valve can achieve an effect of splitting the fluid passing the surface of the valve body, so that the pressure effectof the fluid to the valve body is reduced, and the valve body is not easily swelled. Even if the valve body is swelled, an anti-crack ring is extruded to deform after the valve body is cracked as a result of the fluid pressure, so that repair particles and crack repairing beads move toward a crack. Under the double action of the pressure of the fluid and an unsmooth crack opening, the crack repairing beads break, and a glue solution flows into the crack, so that the repair particles are solidified in the glue solution to achieve the effect of repairing the crack. The ball valve with the crackcan be still used continuously, serious waste of resources is reduced, the using rate of the ball valve is improved and the service life of the ball valve is prolonged.

Description

technical field [0001] The invention relates to the field of ball valves, in particular to an anti-spill type ball valve. Background technique [0002] Ball valve, the opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids, among which the hard-sealed V-shaped ball valve has a strong shear force between its V-shaped ball core and the metal valve seat of surfacing welding carbide, and is especially suitable for fibers and tiny solid particles. etc. medium. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. According to the driving mode, the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve. [...

AI Technical Summary

Problems solved by technology

[0004] Due to the manufacturing process and other problems, there will be tiny air bubbles inside many ball valves. When the fluid passes through the valve body, the huge pressure of the fluid will cause the air bubbles to burst, crack the valve body, and cause the valve body to burst. In this case, ball valves generally All of them are scrapped, resulting in a serious waste of resources, and the utilization rate of ball valves is greatly reduced
