Problems solved by technology

In fact, if the angle is too large, there is a risk that the hook teeth of the locking insert will not hook onto the socket end when they are placed under pressure, and may be caught on the socket end. sliding and causing the lock to fail

Embodiment Construction

[0015] A sealing and locking assembly according to the invention is shown in FIGS. 1 to 3 , designated as a whole by the reference numeral 2 .

[0016] Seal assembly 2 includes spigot end 4 or male end integral with first tube 6 , socket end 8 or female end integral with second tube 10 , and seal 12 .

[0017] The assembly 2 extends along a central axis X-X. In the following, the expressions "radial", "axial", "circumferential" and "in the meridian direction" will be used with respect to this central axis.

[0018] In section along the meridian, the seal 12 comprises an elastic ring 14 made of a flexible or elastic material, such as elastomer, extending around a central axis X-X, in which a plurality of locking inserts are embedded. pieces 20.

[0019] The elastic ring 14 comprises a solid annular body 16 towards the bottom of the socket and on the inlet side of the socket, an anchoring heel 18 projecting radially outwards, and a circular sealing flange 26 projecting radiall...

Abstract

The inventive composite gland sealing for the interlocking coupling of a housing end piece (8) comprising an anchoring groove (82), a plastic ring (14) and several locking inserts (20). Each locking insert (20) comprises a radially external head (30) provided with a first front projection (50, 52) applicable against the annular front surface (90) of the anchoring groove (82). The head (30) comprises a second frontal projection (52, 50) radially shifted from the first front projection (50, 52). Said invention is used for cast-iron pipe joint.

Description

technical field [0001] The invention relates to an assembly according to the preamble of claim 1 . [0002] Said assembly applies in particular to a sealing and locking assembly of two cast iron pipes. Background technique [0003] Document EP-A-526 373 describes a combined sealing assembly comprising a sealing body, an anchoring heel of elastic material and locking inserts of rigid material embedded in the anchoring heel . The locking inserts are evenly distributed over the entire circumference of the body. Each locking insert is made of metal and has an anchor head designed to rest on the bottom of an anchor groove provided at the end of the socket and a hook tooth adapted to engage in the socket in the outer surface of the end, thereby preventing axial movement that would separate the spigot end from the socket end under axial forces caused by the fluid circulating through the spigot and socket ends pressure generated. [0004] The inclination of each locking insert ...
