Abstract

The connection consists of two tubular pieces (1 and 2) clamped end to end against each other by means of a clamp collar the jaws of which (8 and 9) engage with conical slopes (5 and 6) of the connection pieces. Sealing is obtained by the close metal to metal contact of a support surface (17) with its opposite part. A joint (19) ensures a safety seal in case the contact (17) with the opposite part is not completely sealed.

Description

- I
Connection for Pipes
Pipe connections are known coπprising two tubular pieces each intended to be mounted on the end of a pipe and each providing a flange, each flange providing a conical slope on the side of the respective pipe, the connection ccπprising a clamp collar having a generally V-shaped groove intended to cover the flanges and to press the flanges against each other by engagement on their conical slopes.
The aim of the invention is to improve the reliability of connections of this type and to enable the achievement of perfect sealing both for liquids and for gases within a wide range of temperatures and of pressure or low pressure.
The connection forming the object of the invention is characterised in that one flange displays on its side facing the other flange an annular groove in which a joint is fitted with play, this flange having an annular area of support the average radius of which is smaller than that of the groove, this area of support being formed to engage against another area of support of the other flange.
The attached drawing shows diagrat atically and as an example one form of operation of the object of the invention. Figure 1 is a view in axial section of the two tubular parts of the connection, in a connected position.
Figure 2 shews a sectional view of one of the tubular pieces, in a disconnected position.
Figure 3 is an end view of the connection fitted with its clamp collar.
With reference to Figure 1, the connection consists of two tubular pieces 1 and 2 each displaying a flange 3 and 4 respectively. Each of the tubular pieces is intended to be welded to (secured together with) the end of a pipe. Where the liquid passing through the link is a food substance or is a corrosive liquid, the pipes are generally made of stainless steel and it is obviously worth while forming the pieces 1 and 2 of this material as well. Each flange 3 and 4 has a conical slope, 5 and 6 respectively, at the side of the pipe to which it is attached.
The assembly of the two tubular pieces of the connection is ensured by a clamp collar 7, made up of two jaws 8 and 9 in a sheet of drop forged stainless steel. These jaws are articulated to each other by means of a connecting rod 10 connected with lugs which are welded (bound) to the jaws or are integral with the jaws. At their other end, these jaws are held tight with the help of a lever 11 fixed to the end of a connecting rod 12 which has a connection 13 on the jaw 8, this lever 11 turning a cam-shaped section 14, so as to aPPly pressure to the end of the jaw 9 and bring the latter close to the jaw 8. The closed position of the lever 11 is retained by a spring clip 15.
The two jaws 8 and 9 each have a generally V-shaped groove 16 and are intended to cover the flanges 3 and 4 in order to hold them tightly against each other by engaging on their conical slopes 5 and 6 respectively.
As Figure 2 shews, the tubular piece 1 has an annular support area 17 and an annular groove 18 in which a joint 19 is fitted with play, the thickness of the joint being less than the depth of the groove. Depending on the circumstances this joint will be in metal, in conglomerate fibres or in elastomer. The front face of the flange 4 displays an annular support area 20 which coacts with the joint 19, and a support area 21 engaging the surface 17. When in the state of not being held tightly it is necessary for sufficient play between the joint 19 and the groove 18 to be provided so that when being held tightly the joint can be bent elastically to enable support between the surfaces 17 and 21 and to ensure air- and watertightness.
The flange 3 presents an edge 22 surrounding the joint 19 and the support area 17, this edge being intended to guide with play the front part 23 of the other flange when the two flanges of the connection are brought together. This part 23 has a periphery 24 shaped like a cone in order to facilitate its insertion into the spaced defined by the edge 22 and to ensure the centering of the two annular pieces.
The support area 17 is small so that clamping by the claiηp collar 7 enables a specific high support pressure to be obtained between the two tubular pieces, which is enough to ensure perfect sealing. The joint 19 is provided by way of safety in a case, where as a consequence of careless assembly a foreign body is caught between these metal support areas. It will be seen that the support area 20 which is intended to coact with the joint 19 projects in relation to the support area 21 which has a smaller radius and thus forms a protection avoiding practically all damage to the surface 21 fr π impacts against outside objects.

Claims

Claims
1. Pipe connection, comprising two tubular pieces each intended to be provided on the end of a pipe and each providing a flange, each flange having a conical slope on the side of the respective pipe, the connection comprising a clamp collar having a generally V-shaped groove and intended to cover the flanges and to hold them tightly against each other by engagement on their conical slopes, one of the flanges displaying on its side facing the other flange an annular groove in which a joint is located with play, characterised in that said one flange has an annular support area which is contained in a plane perpendicular to the axis of the respective tubular piece and the average radius of which is smaller than that of the groove, the support area being adapted to be fitted against another area of support of the other flange.
2. A connection according to claim 1, characterised in that the support area of the other flange is adapted to serve at the same time as support for the joint itted in the groove.
3. A connection according to claim 2, characterised in that the thickness of the joint is less than the depth of the V- shaped groove, the support area of the other flange which is adapted to coact with this joint being in projecting relation to the support area of smaller radius so as to be able to enter the groove in order to engage with the joint.
4. A connection according to claim 2, characterised in that one flange presents an edge turned towards the other flange to form a space intended to receive the front part of the other flange, this edge surrounding the aforesaid support areas.
5. A connection according to claim 3, characterised in that the part of the flange for fitting into the aforesaid space has a periphery shaped like a flattened cone serving to facilitate the centering of one piece in relation to the other.
6. A connection according to claim 1, in which the claπp collar is formed by at least two jaws articulated with each other and including means for the mutual clamping of these jaws, characterised in that the jaws are formed by a sheet of drop forged stainless steel.
