FITTING FOR COUPLING TO A PIPE

Abstract

A fitting for coupling to at least one pipe, comprising: a sleeve for receiving the pipe; at least one sealing member to provide a seal between the sleeve and the pipe; a pressure member for applying a pressure to the sleeve and to the pipe; gripper teeth provided on the pressure member and arranged to act on the pipe; and actuation means for exerting a pressure to the pressure member comprising a pressure ring acting on the pressure member through adjoining slanting contacting surfaces of said pressure ring and pressure member, respectively; wherein the at least one sealing member is positioned between the pressure member and the pipe;
wherein the at least one sealing member is connected with or pressed against the sleeve without being positioned between the pressure member and the sleeve.

Claims

1. A fitting for coupling to at least one pipe, comprising: a sleeve for receiving the pipe; at least one sealing member to provide a seal between the sleeve and the pipe; a pressure member for applying a pressure to the sleeve and to the pipe; gripper teeth provided on the pressure member and arranged to act on the pipe; and actuation means for exerting a pressure to the pressure member comprising a pressure ring acting on the pressure member through adjoining slanting contacting surfaces of said pressure ring and pressure member, respectively; wherein the at least one sealing member is positioned between the pressure member and the pipe; wherein the at least one sealing member is connected with or pressed against the sleeve without being positioned between the pressure member and the sleeve.

2. The fitting according to claim 1, wherein the opposite extremities of the at least one sealing member are connected to the pressure member and the sleeve respectively.

3. The fitting according to claim 1, wherein the at least one sealing member is connected with, or pressed against, the sleeve without being positioned between the slanting surfaces of the pressure ring and the pressure member.

4. The fitting according to claim 1, further comprising a clip for attaching the sealing member to the sleeve.

5. The fitting according to claim 2, wherein the at least one sealing member is connected with, or pressed against, the sleeve without being positioned between the slanting surfaces of the pressure ring and the pressure member.

6. The fitting according to claim 2, further comprising a clip for attaching the sealing member to the sleeve.

7. The fitting according to claim 3, further comprising a clip for attaching the sealing member to the sleeve.

Description

DRAWINGS

[0020] The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.

[0021] The disclosure will hereinafter be further elucidated with reference to the drawing.

[0022] In the drawing of a single FIGURE a preferred embodiment is shown of the fitting of the disclosure.

[0023] The FIGURE shows an embodiment of the fitting 1 of the disclosure for application with a pipe 2. The fitting has a sleeve 10 for receiving the pipe 2, at least one sealing member 4 to provide a seal between the sleeve 10 and the pipe 2, a pressure member 5 for applying a pressure to the sleeve 10 and to the pipe 2, gripper teeth 6 provided on the pressure member 5 and arranged to act on the pipe 2, and actuation means 3, 7 that are tuneable from a single point outside the sleeve 10 for arranging that a pressure is applied to the pressure member 5.

[0024] The actuation means 3, 7 comprise a pressure ring 3 acting on the pressure member 5 through adjoining slanting contacting surfaces 11, 11 of said pressure ring 3 and pressure member 5, respectively. This arranges that a force applied to the pressure member 5 in parallel with a longitudinal body axis of the sleeve 10 or the pipe 2, acts on the pressure member 5 with a component perpendicular to said longitudinal body axis of the sleeve 10 on the pipe 2 received in said sleeve 10.

[0025] The sealing member 4 is in accordance with the disclosure positioned between the pressure member 5 and the pipe 2 and is connected with or pressed against the sleeve 10 without being positioned between the pressure member 5 and the sleeve 10.

[0026] One of the further characterizing features of the fitting 1 of the disclosure is that it is provided with said sealing member 4 without same being positioned between the slanting surface 11 of the pressure ring 3 and the slanting surface 11 of the pressure member 5.

[0027] Furthermore it is preferable that opposite extremities of the at least one sealing member 4 are connected to the pressure member 5 and to the sleeve 10 respectively.

DETAILED DESCRIPTION

[0028] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0029] The FIGURE further shows that the fitting 1 of the disclosure is preferably further provided with a clip 13 for attaching the sealing member 4 to the sleeve 10. This makes mounting and dismounting of the fitting very easy without sacrificing reliability.

[0030] Although the disclosure has been discussed in the foregoing with reference to a variety of embodiments of the fitting of the disclosure, the disclosure is not restricted to these particular embodiments which can be varied further in many ways without departing from the disclosure. The discussed exemplary embodiments shall therefore not be used to construe the appended claims strictly in accordance therewith. On the contrary the embodiments are merely intended to explain the wording of the appended claims without intent to limit the claims to the discussed exemplary embodiments. The scope of protection of the disclosure shall therefore be construed in accordance with the appended claims only, wherein a possible ambiguity in the wording of the claims shall be resolved using these exemplary embodiments.

[0031] The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
