Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to connecting two pipes or tubes at their flanges, and more specifically, connecting the flanges with the two pipes or tubes clocked together, i.e., circumferentially angled. About doing.
[0002]
[Prior art]
Pipes or tubes are often clamped together with flanges with fittings that have been used to make fluid couplings, such as for transmitting high temperature and high pressure fluids. The flanges are typically male and female, with the male flange being received inside the female flange. The male flange has an inner ring-shaped wall received within the outer ring-shaped wall of the female flange. An example of such a joint is EG & G Pressure Science, Inc. (Beltsville, Md.) Found in U.S. Pat. No. 4,919,453, entitled "Low Profile V-Joint". In the gas turbine engine industry, particularly in the aircraft gas turbine engine industry, many of the connections are made between bent pipes, which may have complex axial, circumferential, and radial bends. Due to limited space and many tubes and pipes installed in the outer casing of the engine, the relative angular orientation between the two joined pipes, the clocking commonly referred to in the art, Very important. To that end, tabs or other protrusions have been welded to one of the flanges, and mating slots or holes have been cut into the other flange. Clocking of the designed two pipes is achieved when the tabs or protrusions are fitted into slots or holes.
[0003]
[Problems to be solved by the invention]
These clocking configurations require making the tabs and slots and then welding the tabs to their corresponding flanges. This adds cost and time to the manufacturing process and increases the cost of the fluid connection, and therefore, with a clocking configuration that is less costly and time consuming to manufacture compared to current designs, the male flange and Desirably, the female flanges can be clocked together.
[0004]
[Means for Solving the Problems]
The pipe connection device includes a first longitudinally extending pipe section having an annular first flange at a first end thereof, and a second longitudinally extending pipe section having an annular second flange at a second end thereof. including. One of the flanges is a male flange and the other is a female flange. The male flange has a ring-shaped male wall surface extending in the longitudinal direction from a flat surface facing the longitudinal direction of the male flange. The female flange has a ring-shaped female wall surface extending in the longitudinal direction from a first flat surface facing the longitudinal direction of the female flange. The male and female walls are shaped and dimensioned so that the male wall can be received inside the female wall. A detent is formed in the first wall surface by the first wall surface and extends radially from the first wall surface to the second wall surface. A notch extends radially into the second wall surface and is sized and shaped to receive a detent therein. In an exemplary embodiment of the invention, the notch is partially machined into a second wall of the wall. The detent is a recess punched into the first wall surface. The notch can be cylindrical in shape.
[0005]
In an exemplary embodiment of the invention, the notch is formed in the male wall and the detent is formed in the female wall. One embodiment of the present invention includes a clamp having a retaining member with a groove surrounding at least a portion of a flange with a male wall received within a female wall. The grooves and flanges are tapered.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings, like reference numerals refer to like elements throughout the views, and with particular reference to the drawings, FIG. 1 illustrates an exemplary embodiment of a clocking pipe connection apparatus 10 of the present invention. Apparatus 10 connects and clocks a first male tapered peripheral flange 16 and a second female tapered peripheral flange 18 of first coaxial pipe section 12 and second coaxial pipe section 14, respectively. Alignment). For the purposes of this patent, the term pipe includes tubes. Male flange 16 and female flange 18 (as further shown in FIGS. 2 and 3) are each coaxial and abut each other, with an E-shaped seal 19 therebetween. The joint clamp, represented by retaining members 20 and 22, has a circumferentially extending inner V-shaped groove 24 for receiving male flange 16 and female flange 18 therein. The clamp is of a known type, as more specifically described in U.S. Pat. No. 4,919,453, which is incorporated herein by reference.
[0008]
With further reference to FIGS. 2 and 3, the male flange 16 has a ring-shaped male wall surface 30 extending longitudinally from a flat surface 32 facing the longitudinal direction of the male flange. The female flange 18 has a ring-shaped female wall surface 36 extending longitudinally from a first flat surface 40 facing the longitudinal direction of the female flange. Male wall surface 30 and female wall surface 36 are shaped and dimensioned such that when the pipe is connected according to the present invention, the male wall surface is received within the female wall surface. A detent 44 is formed in the first wall surface by the first wall surface, extends radially from the first wall surface toward the second wall surface, and a notch 48 is formed in the radial direction by the first wall surface. It is sized and shaped to extend into two walls and receive a detent therein.
[0009]
In the exemplary embodiment, detent 44 is formed in female wall 18 and notch 48 is formed in male wall 30. In an exemplary embodiment of the invention, notch 48 is partially machined into the male wall. The detent 44 is shown as a recess 52 punched into the female wall 36. Notch 48 may be machined into male wall 30 with a grinder or milling machine and may be cylindrical in shape.
[0010]
An exemplary embodiment of the invention includes a clamp 20 having a retaining member with a groove surrounding at least a portion of the flange with the male wall received within the female wall. The grooves and flanges are tapered.
