Embodiment Construction

[0028] refer to Figure 1-6 , a special processing equipment for the wedge-shaped sealing surface of the wedge-top ball valve body, the processing equipment includes:

[0029] The fixing component is used to connect with the flange of the ball valve body to fix the processing equipment on the ball valve body;

[0030] The grinding assembly includes a rotating rod 4 and a plurality of grinding rollers 8. The rotating rod 4 is arranged in the middle of the fixed assembly. Angle, when the grinding roller 8 is in contact with the sealing surface and rotates around the axis of the rotating rod 4, the sealing surface can be polished;

[0031] The driving part 2 is arranged on the fixed assembly, and is used to provide the driving force required for the rotating rod 4 to rotate around its own axis.

[0032] In the embodiment of applying the above technical solution, the preset included angle between the grinding roller 8 and the rotating rod 4 corresponds to the included angle betw...

Abstract

The invention discloses special processing equipment for a wedge-shaped sealing surface of a wedge top type ball valve body. The processing equipment comprises a fixing assembly, a grinding assembly and a driving part; the fixing assembly is used for being connected with a flange plate of the ball valve body so as to fix the processing equipment on the ball valve body; the grinding assembly comprises a rotating rod and a plurality of grinding rollers, the rotating rod is rotationally arranged in the middle of the fixing assembly, the multiple grinding rollers are symmetrically arranged on the peripheral side of the rotating rod, included angles are formed between the grinding rollers and the rotating rod, and when the grinding rollers make contact with the sealing surface and rotate around the axis of the rotating rod, the sealing surface can be polished; and the driving part is arranged on the fixing assembly and used for providing driving force needed by the rotating rod to rotate around the axis of the rotating rod. The rotating rod is driven to rotate through the driving part, then the grinding rollers are driven to rotate to grind the sealing surface, the grinding assembly formed by the rotating rod and the grinding rollers is regular and symmetrical in structure, and therefore higher grinding precision is achieved.

Description

technical field [0001] The invention belongs to the technical field of special processing equipment for sealing surfaces, and in particular relates to special processing equipment for the wedge-shaped sealing surface of a wedge top ball valve body. Background technique [0002] The wedge-top ball valve is a top-mounted ball valve. The wedge-top ball valve inherits the advantages of easy replacement of the spool and seals of the top-mounted fixed ball valve, saving time and effort. [0003] In order to ensure the stability of the seal, the inner wall of the valve is inclined to form a wedge-shaped sealing surface, so that the contact between the seal and the sealing surface can be closer, and the sealing surface needs to be polished to form a smooth surface. For a valve body that is cylindrical as a whole, the sealing surface in its inner wall is conical. [0004] In the prior art, it is common to use turning for grinding. The specific operation is to sleeve the valve body o...
