A ball valve ball arc incision processing equipment

Abstract

The invention relates to equipment for processing an arc-shaped notch in a ball of a ball valve. The equipment for processing the arc-shaped notch in the ball of the ball valve comprises a bottom plate, a sleeving column, a side vertical plate, a limiting plate, an inner supporting mechanism and a locking mechanism, wherein the side vertical plate is mounted on the top of the left end of the bottom plate; the sleeving column is positioned on the upper side of the middle of the bottom plate; the left side surface of the sleeving column is connected with the side vertical plate; the limiting plate is mounted at the left end of the sleeving column; the bottom of the limiting plate is connected with the top of the bottom plate; the sleeving column has a hollow structure; the inner supporting mechanism is distributed in the sleeving column; the locking mechanism is mounted on the limiting plate; and the inner supporting mechanism comprises a spiral rod, a contact plate, a connecting column,an inner supporting plate, an adjusting column and a rotating body. By the equipment for processing the arc-shaped notch in the ball of the ball valve, the problems that when a ball of an existing ball valve is grooved by cutting, the ball of the ball valve is not locked firmly, the locking effect of the ball of the ball valve is poor, the ball of the ball valve may rotate at a certain angle, andthus, the grooving effect of the ball of the ball valve is poor can be solved.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing, in particular to a ball valve ball arc-shaped notch processing equipment. Background technique [0002] Ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of media. Ball valves are widely used in petroleum refining, long-distance pipelines, chemical municipalities, steel and other industries; Turning the handle 90 degrees can drive the ball of the ball valve to rotate, so as to complete the switch control. [0003] There is a cylindrical hole in the middle of the ball valve sphere, and the upper end of the ball valve sphere needs to be slotted so that the rotating handle at the outer end can be inserted into the groove of the ball valve sphere and drive it to rotate synchronously; the existing groove processing of the ball valve sphere requires a ball valve The ball is locked, and then the upper end of the ball valve is grooved by a cutt...

AI Technical Summary

Problems solved by technology

[0003] There is a cylindrical hole in the middle of the ball valve sphere, and the upper end of the ball valve sphere needs to be slotted so that the rotating handle at the outer end can be inserted into the groove of the ball valve sphere and drive it to rotate synchronously; the existing groove processing of the ball valve sphere requires a ball valve The ball is locked, and then the upper end of the ball valve is grooved by a cutting machine. The existing ball valve ball is generally locked by the extrusion of the locking plate when the ball valve ball is cut and grooved. The locking plate cannot target the structure of the ball valve ball. Locking it will result in poor locking effect. Due to the excessive locking force of the locking plate, the outer surface of the ball valve sphere will be deformed to a certain extent, which will affect the sealing performance of the ball valve sphere, and the ball valve sphere is a smooth spherical structure. Rotation at a certain angle will occur when the ball valve ball is not grooved.
