Description

 DESCRIPTION The present invention relates to a device for orienting a pipe by interposing a beveled annular seal between two connecting pieces to be connected.

During plumbing work, we are often forced to solve the difficulties of tight connections due to the imprecision of alignment of the pipes at their junction point, such as the frequent case of pipe junctions by connection of a flanged pipe on a male thread from one end of a pipe or a connecting device. Or as in the case of a mixing valve connection on two non-parallel water inlet pipes.

In such a situation the operator is often obliged to correct the orientation of the pipes or to create a tension on the piping in order to be able to seal the connections of flanged pipes or flanged pipes on threaded pipes.

The difficulty is all the greater when the intervention space is small or difficult to access. This always results in a loss of time and often degradation of the piping.

To remedy such situations, the present invention relates to a device for orienting a pipe by interposing a beveled flat annular seal between two planar contact surfaces of the pipe elements to be joined. This process makes it possible to orient a flanged or flanged pipe in such a way as to make a tight connection possible without creating tension when connecting pipes or devices whose axes of the joining elements form a straight line deflected at the point junction.

Figure 1 shows the beveled annular seal (1). Figure 2 shows the beveled annular ring (10).

FIG. 3 represents the device for orienting a pipe (14) by interposing a beveled annular seal (1) between junction surfaces (16) and (22), according to an assembly by flanges.

FIG. 4 shows the device for orienting a pipe (14) with a flange (15) on a junction piece (21) with a male thread, the clamping sleeve (13) is presented in section.

The bevelled annular seal (1) makes it possible to voluntarily create an axis deviation (8) of an appliance or a pipe (14) relative to its connection point (16) to deflect in front of an obstacle appearing on the initial axis line (9).

This invention consists of an annular seal (1) with bevelled planar contact surfaces (2) and (3), by regular decrease of the thickness between the two ends (4) and (5) of a direction line. of the diameter, while its thickness is constant relative to the two ends (6) and (7) of a line of direction perpendicular to the line of direction of the diameter at the ends (4) and (5) whose thicknesses are different. The beveled annular seal (1) is interposed between two planar contact surfaces (16) and (22) of two devices or pipes (14) and (21) to be connected to create a deviation from the axis line (8) d 'an apparatus or pipe (14) to be connected with respect to the axis line (9) of the apparatus or pipe (21) to which it connects.

This annular seal (1) with bevelled planar contact surfaces (2) and (3) can be provided on a planar contact surface with an adhesive (20) allowing it to be kept stable during its use where it cannot be guided, such as for a mixing valve connection where it is covered by the clamping sleeve before being compressed. An annular ring (10) with bevelled flat contact surfaces (11) and (12) is added to the beveled annular seal ( 1) as well as a clamping sleeve (13) to allow the deviation of the orientation of the axis line (8) of a connection of a pipe (14) with flange (15) relative to the axis (9) of a connecting piece (21) comprising a male screw pitch.

The annular ring (10) with the beveled flat contact surfaces (11) and (12) has the same decrease in thickness as the beveled annular seal (1).

The bevelled annular ring (10) may have a section in its thickest part (19), so that it can be moved apart to fit onto a pipe in place. The outside diameter of the beveled annular ring (10) is equal to the diameter of the beveled annular seal (1) with which it is associated, while the inside diameter is greater than the pipe (14) on which it fits so as to leave a clearance between the ring (10) and the pipe (14) to allow the difference in orientation of the axis (8) of the pipe (14) relative to the axis of the ring (10).

 For implementing the device for orienting the axis line (8) of a flanged pipe (14) (15) relative to the axis (9) of the junction piece (21) with pitch male screw, the beveled annular seal (1) is interposed between the flange (15) of the pipe (14) to be connected and the flat contact surface (16) of the connecting piece (21) to be joined. The bevelled annular ring (10), provided with an adhesive (17) on its contact surface which is to rest against the collar (15) is positioned opposite to the position of the beveled annular seal (1), so that the direction line of the ends (18) and (19) of the outside diameter of the beveled annular ring (10) places the inclination of the beveled annular ring (10) in the opposite direction relative to the inclination of the beveled annular seal ( 1).

A clamping sleeve (13) covering the beveled annular ring (10) as well as the flange (15) of the pipe (14) and the beveled annular seal (i) is screwed onto the connecting piece (21) with a male thread to create by its internal face a pressure on the beveled annular ring (10) pressing the flange (15) against the beveled annular seal (1) and compressing it between the flat surface (22) of the flange (15) and the flat surface (16) of the connecting piece (21) with male thread, thus ensuring the locking of the sealed assembly. The beveled annular seal (1) is designed in a range of beveled annular seals (1) whose thickness between the opposite ends (4) and (5) of the line of direction of the diameter is differently decreasing in order to be able to give different inclinations to the device for orienting a pipe (14) relative to the connection point (16) and for allowing the beveled annular seal (1) to be interposed as best as possible between two flat contact surfaces (16) and (22) pipes or apparatus to be connected having, by their imprecise mounting, a deviation of axis (8) at the junction point (16) by forming a beveled spacing between the two surfaces (16) and (22) having to make a connection where an annular seal must be inserted to seal the assembly.

The device for orienting a flanged pipe (14) (15) by interposing a beveled annular seal (1) between two planar contact surfaces (16) and (22) to be connected is also designed to create a difference in orientation of the axis line (8) of two devices or two pipes (14) connecting to a pipe (21) comprising at the two ends a thread of male screw to be able to form a fitting of which each pipe (14) with collar (15) connected thereto by a clamping sleeve (13) can be oriented differently, so as to be able to carry out a diversion of piping to be connected relative to the axis line (9) of a device or '' a pipe (21) comprising at each end a male thread with a planar contact surface (16) where a beveled annular seal (1) must be inserted between two planar contact surfaces (16) and (22) in front make a junction to allow the deviation of the axis line (8) of each of the two devices or pipes (14) connected.

The beveled annular seal (1) can be rigid or semi-rigid and of a narrow thickness, so that it can be interposed between two contact surfaces (16) and (22) of two parts to be connected (14) and (21 ) whose spacing provided for the location of the annular seal is narrow.
