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.
