Y ATTORNEY COMPARTMENTED UNDERWATER EQUIPMENT This is a continuation of application Ser. No. 855,110, filed Sept. 4, l969,-and since abandoned.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention concerns underwater equipment for use in oil and/or gas well operations and particularly concerns a plug-in pressure-compartmented envelope or package for containing components for use in underwater operations and a receptacle for such package.
A major consideration in the effective utilization of underwater equipment components is the packaging thereof for easy installation and removal for maintenance purposes. The packaging member (referred to herein as retrievable body member or body member") should have structural features sufficiently versatile to permit mounting a variety of components such as valves, diverters, chokes, pig inserters, sensors, actuators, etc., and to provide a pressure-compartmentalized envelope, together with the receptacle structure. Further, insertion and removal of the retrievable body into and from the receptacle should require only simple plug-in and withdrawal motions capable of being performed by remotely operable manipulators or by divers.
SUMMARY OF THE INVENTION Briefly, the invention resides in apparatus for mounting underwater equipment comprising a body member; a receptacle having a chamber formed therein for receiving said body member, said chamber being defined by at least two walls and an entrance opening for said body member, at least one of said walls slanting inwardly from said entrance so as to gradually decrease the cross-sectional area of said chamber from the entrance thereof, and at least one other of said walls extending inwardly linearly from said entrance, said receptacle having flow path openings therein extending from the exterior thereof through at least two of said receptacle walls; said body member having a cavity formed therein and having counterpart external walls with respect to said receptacle walls for mating therewith and flow path openings in said body member extending from said cavity through said body member wall to meet flush and in alignment with said openings in said receptacle walls when said body member is inserted in said receptacle chamber. Sealing means are arranged on each side of said wall openings for sealing off the space between the mating surfaces of said receptacle and body member. Locking means is provided on the entrance of the receptacle and on the body member cooperating to releasably lock the body member in the receptacle chamber. A flow control valve or other operating component is packaged in the body member cavity. The linearly extending walls of the body member and receptacle may be provided with guide members such as a lug and groove to ensure that the body member is properly positioned in the receptacle cavity.
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a partly sectional view of a body member containing a valve and mounted in a receptacle in accordance with the teachings of the invention;
FIG. 2 is an end view of the receptacle illustrated in FIG. 1;
FIG. 3 is a sectional side view of the receptacle illustrated in FIG. 1;
FIG. 4 is an end view of the body member illustrated in FIG. 1;
FIG. 5 is a side view of the body member illustrated in FIG. 1; and
FIG. 6 is another side view of the body member illustrated in FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. l-3, there is shown a fixed dimension receptacle 10 permanently mounted in an underwater manifold or piping system (not shown). Receptacle 10 is formed with a bore or chamber 1 l which is defined by four walls 13, 14, and 16. Receptacle 10 is also formed with two openings or passageways 17 and 18 located on opposite sides of chamber 11. Opposing walls 13 and 14 slant inwardly from the entrance of receptacle 10 across the areas of openings 17 and 18 in walls 13 and 14, respectively. Entrance 20 of receptacle 10 is also provided with a flange 21 containing a plurality of spaced-apart locking lugs 22. Opposing walls 15 and 16 extend linearly and each is provided with a guide key-way 23 and 24.
Referring to FIGS. 1 and 4-6, a body member 25 for insertion and retrieval from chamber 11 of receptacle 10 is formed with four exterior walls 26, 27, 28 and 29. Walls 26 and 27 slant in the same direction and same angle as walls 13 and 14, respectively, or receptacle 10. Body member 25 is provided with a cavity 30 and openings or passageways 31 and 32 which are flush and aligned with openings 17 and 18, respectively, of receptacle 10. Linearly extending walls 28 and 29 have keys 35 and 36, respectively, for engagement in guide keyways 23 and 24, respectively. The rear of body member.
25 contains a flange having a shoulder 42. As seen in FIG. 1, a lock ring 41 has a shoulder 41a which engages shoulder 42 of flange 40 and, upon rotation, engages locking lugs 22 of receptacle 10. A valve housing is bolted to body member 25 by a plurality of bolts and nuts 52, 53. A valve stem is connected to a valve gate 56 shown positioned in cavity 30. Suitable seal rings 57 and 58 and O-ring seals designated 59 are provided. Valve stem 55 is connected at its other end to a rotatable nut 60. Valve stem 55 extends through an opening 61 in valve housing 50 and through an opening 62 in body member 25. Sealing rings a,b and 7la,b mounted on the outer wall of body member 25 are positioned on each side of connecting passageways 17-31 and 32-18 when body member 25 is fully inserted in receptacle 10. A seal test port is connected to the mating surfaces of receptacle 10 and body member 25 between seals 70a,b; 7la,b. As seen in FIG. 4, slots and 81 are formed in coupling 51 and body member-25 as a guide for gate 56.
As shown in FIG. 1, the planes of the sealing surfaces are arranged to provide full-bore passage of fluid flow without change of direction. The engagement of the sealing surface is with a simple, single rectilinear motion of insertion of body member 25 into receptacle l0. Seals 70a,b and 71a,b may be mechanically energized seals. The sealing gaskets or rings 70a,b, 7 la,b are preferably retrievable with body member 25 to permit replacement of deformable seal members. Any number of seal surfaces can be provided to achieve the desired degree of pressure compartmentation needed.
In operation, body member 25 with the valve apparatus including housing 50, rotatable nut 60 and valve stem 55, secured to body member 25 by studs 52 and nuts 53, is positioned adjacent receptacle l and partly inserted into the receptacle by a manipulator tool, now shown. At this time, guide keys 35 and 36 engage guide key-ways 23 and 24. The manipulator tool continues insertion of body member 25 into receptacle until the surfaces mate as illustrated in FIG. 1 and seals 70a,b and 7la,b seal off passageways 18-32, 31-17. The manipulator tool rotates locking ring 41 until the locking ring engages and looks into lugs 22. Alternatively, the locking ring may be threaded into threads formed on receptacle l0. Locking may otherwise be achieved by conventional mechanical connections; i.e., flanges or hubs or clamps.
Gate 56 of the valve may be actuated by a manipulator tool connected to rotatable nut 60 to cause gate 56 to be positioned in or out of the flow passageways.
The procedure for removing body member 25 and the valve connected to it from receptacle 10 is the reverse of that described above.
Although in the preferred embodiment, two opposing linear walls and two opposing slanted walls are used, other wall arrangements are possible so long as two (one set) mating walls slant inwardly from the entrance of the receptacle in order to effect a wedge-type seal.
Having fully described the apparatus and objects and advantages of our invention, we claim:
