Abstract

Toothed seal ring (1) for pipe joining wherein the external surface (3) has a saw tooth profile and wherein the internal surface (4) also has a saw tooth profile but with teeth in the opposite direction to that of the teeth present on the external surface (3) .

Description

TOOTHED SEAL RING FOR PIPE JOINING
DESCRIPTION
This utility model consists of a clamp ring to apply in the devices used for joining polyethylene pipes. As we know, in order to make polyethylene hydraulic piping, a series of pipes must be joined,. for this, the most widely used mechanical methodologies foresee the use of the so-called compression joints or the creation of a socket at the end of the pipe to be joined so that it can accommodate the end of another section of pipe making up the piping. With the aim of guaranteeing a perfect connection from both a mechanical and hydraulic viewpoint, the latter method of connecting pipes foresees the use of a ring to be fitted in a special housing on the internal surface of the socketed pipe which has the job of holding the surfaces in contact with the pipe, developing the necessary forces of attrition. The rings currently used for this present a series of problems caused by the fact that the values of the frictional force developed are of a modest size, moreover, they decrease in time with deterioration and ageing of the plastic material used. However, a problem with the currently used rings with a trapezoid section consists of the fact that excessive values of traction exerted axially on the pipes may determine their release and affect operation.
The aim of this model is to provide a ring to fit to a suitable housing in the vicinity of the edge of the socket of a polyethylene pipe with the job of fastening the latter with the pipe to be joined. This ring thus solves the problem of preventing accidental detachment of two jointed pipes, increasing the friction force between the contact surfaces of the pipes themselves. These aims are achieved by the ring in the model described below in a preferable . implementation but not limited by further possible developments within the model, with the aid of the two attached tables of drawings which illustrate the following figures: fig. 1 An assonometric view of the toothed ring; fig. 2 A section of the toothed ring; fig. 3 A view of the two pipes; fig. 4 An exploded view of the two pipes with the applied ring; fig. 5 A view of the ring in a further version; fig. 6 A lateral view of the toothed ring.
As illustrated in the attached drawings, seal ring 1 is of a rectangular section and the internal and external surfaces have a saw toothed profile 3 and 4. The particular section gives the ring two grips: An internal one 4 and an external one 3. The direction of the individual teeth is counterlaid so that friction force is exerted in a single direction, that is the one which tends to make the pipes come off.

Claims

1. "Toothed seal ring for pipe joining" characterised by the fact that the external surface (3) has a saw tooth profile and by the fact that the internal surface (4) also has a saw tooth profile but with teeth in the opposite direction to that of the teeth present on the external surface (3).
2. Ring described in claim 1, characterised by the fact that the toothed profiles (3) and (4) can be of any shape and of different geometry from the saw tooth.
3. Ring described in the previous claims, characterised by the fact that it can be made of any type of plastic or metal material.
