Description

Automatic assembling equipment and assembling method for ball valve

Technical Field

The invention relates to a valve, in particular to automatic assembly equipment for a ball valve and an assembly method thereof.

Background

The valve is an important control component in a fluid transportation system, and is often connected to a pipeline, and the opening and closing degree of the valve can be operated to control the flow of fluid in the pipeline and control the flow speed of the fluid. In addition, there are various types and functions of the valve, and the valve may be classified into a shut-off valve, a check valve, a regulating valve, a vacuum valve, etc. according to the purpose. The shut-off valve can be classified into a gate valve, a shut-off valve, a diaphragm valve, a ball valve, a plug valve, a butterfly valve, etc. according to the structure thereof, wherein the ball valve is particularly suitable for being used as a switch to control the flow or cut-off of fluid in a pipeline, and the ball valve is widely applied to industries such as petroleum refining, long transportation pipelines, chemical industry, paper making, etc. and daily life.

The ball valve is named because the valve core is spherical, the valve core is an opening and closing piece, the spherical valve core of the ball valve is a sphere with a cylindrical channel, the spherical valve core of the ball valve rotates around an axis vertical to the channel, and the spherical valve core rotates along with the valve rod to achieve the purpose of opening and closing the channel. The ball valve can drive the valve core to rotate and close tightly only by rotating the valve rod by 90 degrees with smaller moment, and can be assembled with different external driving devices to control the opening and closing of the ball valve according to requirements.

When the ball valve rotates 90 degrees, the cylindrical channel in the ball valve is isolated from the channel of the valve body, medium flow in the valve body is blocked, and when the ball valve rotates 90 degrees, the cylindrical channel in the ball valve is communicated with the channel of the valve body again, so that the medium in the ball valve is restored to flow to form a passage.

In the traditional ball valve assembly process, each part of the ball valve is assembled in a manual mode, when the ball valve is assembled manually, the production speed is often influenced by the proficiency of an assembler, and different assemblers can also have different assembly speeds, so that the assembly speeds of different annular joints form a certain speed difference, after a certain time, the assembly speed of a certain link can not consume semi-finished products generated in the previous link, thus forming bottleneck to influence the production efficiency, the assembler must be increased to eliminate the bottleneck, and the personnel cost is increased; meanwhile, assembly errors can occur to unskilled assembly personnel, so that yield is reduced, rework cost and labor hour are increased, further, the human body cannot continuously produce the assembly for 24 hours in the whole day, and if the assembly personnel adopt a shift system to maintain 24 hours for production, the health of production personnel can be damaged.

On the other hand, glue is often used for bonding and sealing in the traditional ball valve assembly process, proper glue amount can not be almost applied every time by manually applying the glue, a ball valve semi-finished product after the glue is applied is naturally solidified by waiting 24 hours, a large amount of time is consumed for natural solidification, the whole production period is prolonged, meanwhile, the natural glue solidification time can be different due to different seasons and air temperatures, the solidification process becomes unstable, and the fact that whether the glue is completely solidified or not is difficult to determine because the applied glue amount is not accurately quantified, so that uncertainty exists in the follow-up steps.
