Description

Novel three-piece forged steel ball valve

Technical Field

The utility model relates to the technical field of valves, specifically be a novel three-piece formula forged steel ball valve.

Background

Ball valve, the open-close piece (ball) is driven by the valve rod and rotates around the axis of the ball valve. The hard seal V-shaped ball valve can also be used for regulating and controlling fluid, wherein a V-shaped ball core of the hard seal V-shaped ball valve and a metal valve seat of the build-up welding hard alloy have strong shearing force, and the hard seal V-shaped ball valve is particularly suitable for media containing fibers, tiny solid particles and the like. The multi-way ball valve can flexibly control the confluence, the diversion and the switching of the flow direction of the medium on the pipeline, and can close any channel to connect the other two channels. The valve is generally horizontally installed in a pipeline, and the three-piece forged steel ball valve and the gate valve belong to the same type of valve, except that a closing member of the three-piece forged steel ball valve is a ball body, and the ball body rotates around the center line of the valve body to achieve opening and closing. Ball valves are used in pipelines primarily to shut off, distribute and change the direction of flow of media. Three-piece ball valves are a new type of valve that has been widely used in recent years, and are generally installed horizontally.

The equipment operational flexibility ratio of tradition is relatively poor at present, and the not convenient to detach of tradition equipment leads to maintaining the maintenance comparatively troublesome simultaneously, and above these problems just need improve traditional equipment, therefore we propose a novel three-piece formula forged steel ball valve here.
