Embodiment 1

[0035] Such as Figure 1-3 As shown, this embodiment provides a ball valve assembly tool, which cooperates with the spring seat 11 in the ball valve body 10 to assemble the ball 12 . Ball valve assembly tooling includes:

[0036] An expansion assembly, which includes a tapered inner bushing 5, and an expansion sleeve 4 sleeved on the tapered inner bushing 5, the inner surface of the expansion sleeve 4 cooperates with the outer wall of the tapered inner bushing 5 , the expansion assembly is suitable for assembly in the spring seat 11, and forms a combination with the spring seat 11 by expansion;

[0037] The drive assembly is adapted to extend into the valve chamber 101 of the ball valve body 10, and is detachably connected with the tapered inner bushing 5 installed on the assembly in the valve chamber 101, for driving the valve chamber 101. The tapered inner bushing 5 moves along the expanding direction or the releasing direction, and when moving along the expanding directio...

Embodiment 2

[0049] This embodiment provides a ball valve assembly process, using the ball valve assembly tooling of Embodiment 1, including the following steps:

[0050] Put the expansion assembly composed of the expansion sleeve 4 and the tapered inner sleeve 5 into the spring seat 11, and expand it with the spring seat 11 to form a combination;

[0051] Put the above assembly into the valve chamber 101 of the ball valve body 10;

[0052] Extend one end of the driving assembly into the valve cavity 101, connect with the tapered inner bushing 5 on the assembly, and drive the tapered inner bushing 5 to move in the direction of expansion, and the direction of expansion is the same as The direction away from the installation position of the sphere is the same;

[0053] Putting the ball 12 into the valve chamber 101;

[0054] The driving assembly drives the tapered inner bushing 5 to move toward the direction of releasing the tensioning force, so that the spring seat 11 is separated from th...

Abstract

The invention relates to the technical field of valve assembly, in particular to a ball valve assembly tool and an assembly process. The ball valve assembly tool comprises an expansion assembly and adriving assembly, wherein the expansion assembly can be expanded and fastened with a spring seat to form a combined body; and the driving assembly is used for driving the spring seat to move in a valve cavity in the direction away from the ball body installing position. The arrangement mode is assembled in the spring seat in an expansion mode through the expansion assembly, so as to form the combined body, the combined body in the valve cavity is driven by the driving assembly, so as to drive the spring seat to move in the valve cavity, so that a containing space capable of installing the ballbody is formed in the valve cavity, and the valve body cannot be damaged in the valve assembly process.

Description

technical field [0001] The invention relates to the technical field of valve assembly, in particular to a ball valve assembly tool and an assembly process. Background technique [0002] When assembling the ball valve, the ball needs to be lowered from the opening of the valve body. Due to the restriction of the valve seat, it cannot be directly put into the valve body. At this time, it is necessary to rely on the tooling to back off the valve seat, so it is often necessary to design a specific tooling. [0003] In order to realize the valve seat retreat to assemble the ball valve, the Chinese patent (CN208034570U) discloses a tooling structure for convenient installation and disassembly of the top-mounted ball valve ball, which includes cam discs, studs, limit fixing plates, crowbars, and cam discs It forms a crowbar tool with a crowbar. The cam disc is stuck in the valve seat groove. Two plates are welded at the center of the cam disc. There is a sliding groove on the plate...
