Embodiment Construction

[0014] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0015] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0016] Such as figure 1 As shown, according to the pre-glue method of the joint of the pipeline according to the specific embodiment of the present invention, glue is applied on the thread of the joint at the processing site after the joint of the pipeline is processed, and then the joint is transported to the assembly site for assembly .

[0017] Gluing method of the present invention comprises the steps:

Abstract

The invention discloses a pre-gluing method for a pipeline joint. The method comprises the following steps: after finishing processing the joint, clearing away sharp edges and burrs of the joint, examining whether the defects of scratches and collisions exist on a thread and a sealing surface of the joint; cleaning the surface of the joint if no defects of scratches and collisions exist on the thread and the sealing surface of the joint; drying the surface of the joint; pre-gluing glue on other threads except a first thread of the joint; solidifying the surface of the glue, solidifying and drying the outer layer of the glue, and enabling the inner layer of the glue to be in an emulsion state; transporting the joint coated with the glue to an assembly field and assembling, extruding the emulsion glue in the inner layer of the glue, and filling the extruded emulsion glue in a gap of the sealing surface to form an elastic sealing tape. The operation of applying the glue on the thread of the joint is arranged after the processing of the joint, and is separated from the assembly of an engine, so that the gluing procedure does not affect the assembly efficiency of the engine.

Description

technical field [0001] The invention relates to the field of engines, in particular to a pre-glue method for joints of pipelines. Background technique [0002] In order to ensure the tightness of the threaded joints, the following two methods are used when installing pipe joints for parts on the engine assembly line: [0003] One is the method of artificially applying glue on the threaded surface of the pipeline joint. When applying glue manually, the first tooth of the end must not be glued and kept clean to prevent the glue from entering the downstream parts and causing secondary pollution. Curing in air for too long. The speed of manual gluing is low, resulting in low assembly efficiency; and it is difficult for the gluing personnel to accurately grasp the amount of glue. In order to ensure a complete and effective seal, the gluing personnel often apply more glue, which not only causes glue waste, but also glue in the future. Installed immediately before curing, when s...
