Problems solved by technology

[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 limite...

Method used

As shown in Figure 1, the embedded ferrule seal structure is mainly composed of a joint body 1 with a 24 ° conical counterbore form, a ferrule 2 with a sharp inner edge, and a nut 3 that acts as a compression. composition. Among them, the joint body of the 24° tapered hole is required to be directly processed on the mounting part in the form of a counterbore; the upper end of the nut is a hexagonal force nut, the middle is an external thread connecte...

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.

Example Embodiment

[0008] The structural principle and working principle of the present invention will be further described in detail below with reference to the drawings and embodiments.
[0009] Such as figure 1 As shown, the built-in ferrule sealing structure is mainly composed of a connector body 1 with a 24° conical counterbore, a ferrule 2 with a sharp inner blade, and a nut 3 for compression. Among them, the connector body with a 24° tapered hole is required to be directly processed on the mounting part in the form of a counterbore; the upper end of the nut is a hexagonal afterburner nut, the middle is an external thread connected with the connector body, and the lower end is a compression boss for a ferrule. When tightening the nut, the ferrule is pushed into the 24° cone hole and deformed accordingly, so that the ferrule and the conical surface of the joint body form a spherical contact seal; at the same time, the inner edge of the ferrule is embedded in the outer wall of the steel pipe to be sealed, on the outer wall A circular groove is pressed out, which plays a role of reliable sealing.
