Description

Technical Field

[0001] The invention relates to the field of sealing pipeline system maintenance, and in particular to a sealing cone gasket removal device based on the sealing pipeline and the sealing pipeline. Background Art

[0002] In sealed pipeline systems, such as high-pressure oil pipes, metal sealing cone gaskets are often used at joints to ensure the sealing effect due to considerations of sealing and durability. During the docking process, the soft metal cone gasket is squeezed and deformed by the docking pressure, causing the cone gasket to be stuck in the concave joint. There is currently no safe and quick sealing cone gasket removal tool on the market. On-site staff generally use small screwdrivers, small metal blades, etc. to pry and remove them. This method of removing the sealing cone gasket will cause scratches on the cone surface, resulting in poor sealing of the pipeline or even sealing failure. In addition, this removal method is very demanding on the operator's skills, and it is easy to damage the pipeline if you are not careful. Therefore, there is an urgent need for a removal device and a sealed pipeline that is not easy to scratch the conical surface of the pipeline and is convenient to remove the sealing cone gasket. Summary of the invention

[0003] The technical problem to be solved by the present invention is, in view of the above-mentioned problems, a sealing cone gasket removal device and a sealing pipeline based on a sealing pipeline are provided. When the metal sealing cone gasket is compressed and cannot be removed, the cutting edge of the spiral cutter head is used to press and rotate it into the surface of the metal gasket, and the sealing cone gasket is detached from the cone surface using a pressing handle. It is not easy to scratch the sealing pipeline and is convenient to operate.

[0004] The technical solution adopted by the present invention is as follows: a sealing cone gasket removal device based on a sealing pipeline, comprising a pressing handle, a screw sleeve and a fixing assembly, wherein the screw sleeve is used to be fixed to the sealing pipeline, and the fixing assembly comprises a pull rod and a spiral cutter head, wherein one end of the pull rod is inserted into the screw sleeve and connected to the spiral cutter head, and the other end is fixed to the pressing handle through a pin shaft, and an eccentric cam is provided at one end of the pressing handle provided with the pin shaft, and the eccentric cam is abutted against the outer wall of the screw sleeve, and the spiral cutter head is an inverted boss structure, and the outer side wall of the spiral cutter head is provided with a spiral cutting edge, and the spiral cutting edge is used to fix the sealing cone gasket.

A second threaded position matching the first threaded position is provided on the outer wall of the pipeline housing. The pipeline housing is also provided with a conical interface, and the sealing cone gasket is provided on the conical interface. When removing the cone gasket, first select a screw sleeve and a cutter head. Pass the pull rod through the guide sleeve, and tighten the pull rod and the replaceable spiral cutter head. Screw the screw sleeve onto the external thread of the structure to be removed. Press the pressure handle and rotate it to embed the cutting edge of the spiral cutter head into the metal sealing cone gasket. Press the pressure handle and pull the pull rod to remove the spiral cutter head and the cone gasket together.
