Embodiment Construction

[0039] Such as figure 1 and figure 2 As shown, the invention relates to the coupling of any type of male tubular part 2 in a female tubular part 4, and more particularly to the installation of an annular seal 6 between the coupled tubular parts. The term "tubular part" is to be understood in a very general sense, as it equally covers conduits, pipe fittings, end fittings, connectors, etc., i.e. any Tubular elements. Tubular parts are intended for use in any type of application, with any type of fluid, such as water, oil, air, oxygen, etc. The term "annular" covers the general definition, ie any form which is closed on itself, for example that of a torus. The seal may have any type of cross-section; the seal may be, for example, a seal of O-shaped, D-shaped, four-lobed cross-section or the like. Seals can be lubricated or unlubricated.

Abstract

The invention relates to a tool and a method for installing seals. When coupling tubular parts by fitting, the seal (6) interposed between them may roll on itself, be pinched or damaged. Now, a twisted or damaged seal no longer correctly ensures the seal-tightness and it is very difficult to detect this. The present application discloses a tool for installing a seal between a convex component (2)and a concave component (4), including a compression ring (38) to encircle the male part and exert a compression on the seal before producing the join. The tool also includes a tongue (44) that can bepositioned at a chamfered surface (14) of the female tubular part. The tongue (44) makes it possible to offer the pre-compressed seal with the dimensions of the female part a continuous travel makingit possible to prevent any twisting or other effect compromising the seal-tightness.

Description

technical field [0001] The present invention relates to a tool for installing a seal intended to ensure tightness between tubular parts and an installation method using the tool. More specifically, the invention applies to annular seals that can be inserted between different types of tubular parts that are intended to be joined, for example, tubes and couplings, female end fittings and male ends Department assembly. The invention is particularly applicable in the field of aircraft construction and its maintenance. [0002] Seals are widely used on aircraft, depending on the specific application. They ensure, inter alia, tightness between the parts forming the fluid delivery line. [0003] When blind-fitting seals when connecting piping systems, displacement of one part relative to the other may have undesired effects that impair the tightness of the seal provided between the two parts, such as twisting, pinching, etc. compression, damage, deformation, change of one or more...
