Embodiment Construction

[0013] A sleeve used for automatic installation of joints in pipe fittings according to the present invention, see figure 2 and image 3 , the sleeve includes a body 4, on the body 4 is provided with an end opening 1 compatible with the internal thread part of the union, a middle slot 2 compatible with the external thread part of the union, and a driving device The matching interface 3; the end opening 1 is set at one end of the body 4, and the end opening 1 communicates with the middle slot 2; the interface 3 is set at the other end of the body 4.

[0014] The opening at the end is the opening of the internal thread part of the fixed joint, that is, the octagonal (or hexagonal) opening, and the size matches the octagonal (or hexagonal) size, which is a clearance fit. The size of the slot in the middle matches the width of the union, which is a clearance fit. The size of the centering structure matches the diameter of the union, which is a clearance fit. F is a cavity cont...

Abstract

The invention discloses a sleeve for automatically installing a loosen joint in a pipe connector. The sleeve comprises a body, wherein the body is provided with an end opening matched with an internal thread part in the loose joint, a middle notch matched with an external thread part in the loose joint and a port matched with a driving device; the end opening is arranged at one end of the body and is communicated with the middle notch; and the port is arranged at the other end of the body. The sleeve has the advantages that connection efficiency of the loosen joint and a pipeline is improved, the work intensity of an operator is reduced, and the fastening quality of the threads of the pipe connector is improved.

Description

technical field [0001] The invention relates to an installation tool, in particular to a sleeve used for automatically installing a joint in a pipe joint. Background technique [0002] Fittings are used for the layout and connection of metal pipelines, and are widely used in liquid and gas transmission pipelines in railways, ships, industries and buildings. [0003] Unions are used to connect straight pipes, due to the shape of unions (joints) see figure 1 As shown, the union includes an internal threaded part 11 with a straight edge and a cylindrical external threaded part 12. When connecting, the internal threaded part 11 with a straight edge is connected to the pipeline on one side, and the pipelines on both sides pass through two Only the cylindrical external threaded parts 12 that are unioned are connected together. Due to the limitations of the working head and the matching sleeve structure of the automatic tool, the automatic tool cannot be used directly, so the co...
