Problems solved by technology

[0002] A large number of plug-type air-cooled tube bundles are used in the petrochemical industry. However, during equipment maintenance, the plug sealing surface on the tube box is extremely prone to bumps and scratches. At the same time, the medium will also cause corrosion damage to the sealing surface during use. The sealing performance is damaged to cause leakage, so the sealing surface needs to be repaired, and the sealing surface of the pipe box plug hole repaired on the petrochemical industry site needs special tools to repair

Embodiment Construction

[0012] specific implementation

[0013] Such as figure 1 As shown in the figure, a tool for repairing the sealing surface of a screw plug includes a casing 1 through which both ends are connected. The casing 1 is rotatably connected with a rotating screw 2, and one end of the rotating screw 2 is equipped with a cutter head 3, and the other end is used for connecting with the power source. connect. The housing 1 is in contact with the end of the pipe with the sealing surface of the plug, and then a power source is applied to the rotating screw 2. The screw rotates along the housing 1 and advances axially, and the cutter head 3 connected to the rotating screw 2 The sealing surface is re-tapped and repaired to ensure the tightness of the connection between the plug and the sealing surface.

[0014] During the repair process, the tooling will vibrate, resulting in the simple rotation of the screw rod 2 and the housing 1 to easily change the position of the housing 1, resulting i...

Abstract

The invention discloses a plug sealed face repairing tool which comprises a shell with two through ends. A rotating lead screw is rotationally connected with the shell. One end of the rotating lead screw is provided with a tool bit, and the other end of the rotating lead screw is used for being connected with a power source, so the sealed face of a pipeline plug is repaired and can be repaired manually or electrically. The tool and a pipeline can be accurately positioned, and the repairing stability and precision are ensured. The length of the lead screw can be controlled, the repairing lengthis kept, and no additional damage is caused. The hand holding area is increased, and the operation stability is improved.

Description

technical field [0001] The invention relates to a tool for repairing pipelines, in particular to a tool for repairing the sealing surface of a plug. Background technique [0002] A large number of plug-type air-cooled tube bundles are used in the petrochemical industry. However, during equipment maintenance, the plug sealing surface on the tube box is extremely prone to bumps and scratches. At the same time, the medium will also cause corrosion damage to the sealing surface during use. The sealing performance is damaged to cause leakage, so the sealing surface needs to be repaired, and the sealing surface of the pipe box plug hole repaired on the petrochemical industry site needs special tools to repair. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to provide a tool for repairing the sealing surface of a plug, which is used for repairing the sealing surface of a plug hole. [0004] Technical solution: The tool for re...
