Embedded type ferrule sealing structure

Abstract

The invention discloses a novel recessed cutting sleeve sealing structure, which belongs to technical field of pipeline sealing. The recessed cutting sleeve sealing structure mainly comprises a connector body (1) having 24 degrees conical countersunk form, a cutting sleeve (2) having sharp inner edge, a nut playing a role of compaction (3), wherein the connector body (1) having 24 degrees conical hole is required to be processed on an mount in countersunk form; the upper end of the nut (3) is a hexagon reinforcing nut, the middle part is external screw thread connected with the connector body, the lower end is a cutting sleeve compaction boss. When the nut is screwed, the cutting sleeve is pushed into the 24 degrees conical hole and deformed, so the cutting sleeve and the inner conical surface of the connector body form a spherical contact sealing, simultaneously the inner edge of the cutting sleeve is recessed into outer wall of a steel pipe to be sealed, a ring groove is compressed in the outer wall, therefore the reliable sealing effect is achieved. The recessed cutting sleeve sealing structure has simple structure, reliable sealing performance, convenient use, and has the advantage of free of gasket and welding, material saving, good repeatedly assembly and disassembly performance.

Description

technical field [0001] The invention belongs to the technical field of pipeline sealing, is suitable for pipeline systems with oil, gas and water as the medium, and is an ideal medium-high pressure pipeline connector. The range of applications is very wide. Background technique [0002] At present, there are many types of ferrule-type sealing structures, but basically they are convex-type sealing structures, which limits their application range. Some parts cannot be welded due to installation accuracy and coordination requirements, but it is hoped that as many pipelines as possible can be installed in parallel on the same plane with a limited area, but due to processing technology problems, only one plane with a limited area A conventional protruding form of the ferrule fitting body can be processed, which makes the form of intensive installation of parallel pipelines impossible to realize. In addition, in a small device with a small space and a compact structure, the prot...

[0002] At present, there are many types of ferrule-type sealing structures, but basically they are convex-type sealing structures, which limits their application range.

Some parts cannot be welded due to installation accuracy and coordination requirements, but it is hoped that as many pipelines can be installed in parallel on the same plane with a limited area. However, due to processing technology problems, only one plane with a limited area can Can process a conventional convex form of the ferrule fitting body, which makes the form of intensive installation of parallel pipelines impossible to realize

In addition, in small equipment with small space and compact structure, the protruding form of the ferrule joint body occupies a large external space, making installation inflexible or impossible

These are the application limitations of the current ferrule seal structure
