Abstract
A device for holding a circular opening to a valve (42) in aligned relationship to a circular opening to a pipe (44) so that the valve and pipe may be joined together by welding or the like, clamps the same with their openings in coaxial relationship and in close proximity. The device has an elongate inner clamp (40) to engage the aligned inner surfaces and an elongate outer clamp (32) which may be moved by an adjusting collar (28) towards the inner clamp (40). To accommodate pipes and valves having nonaligned outer surfaces, a compensating screw (36) is provided at one end of the outer clamp (32). After the valve and pipe have been tack-welded at spaced points (50), the device is removable by loosening the collar (28) and turning the handle (24) through 90 DEG so that the inner clamp (40) can be withdrawn through the space (46). The valve and pipe can then be completely joined around their openings. <IMAGE>
Description
SPECIFICATION
Device for clamping and aligning a valve and a pipe to be joined together
The present invention relates to a device for supporting a valve and a pipe in aligned relationship so that the same may be joined together.
In plumbing and other manufacturing operations metal valves are often joined to metal pipes. When the valves and pipes are not of types joined by unions or other separate mechanical fasteners, but instead by welding, some means must be provided for holding the same in aligned relationship for connection.
The positioning of the valves and pipes may be accomplished by two individuals, each of whom holds a separate one of the same with openings thereto abutting, while a third individual welds them together. In the alternative, supports such as wooden beams may be used to hold the valves and pipes in aligned relationship for welding. Irrespective of the particular means by which they are positioned for joining, conventional positioning techniques are, to say the least, cumbersome, inconvenient and time intensive, and usually require the combined efforts of more than one individual.
To join a pair of pipes together by welding, an exemplary type of device which enables a single individual to both align and weld the same in end to end relationship is described in U.S.A. Patent No. 4,175,735. However, the device disclosed therein has not proved completely satisfactory for use in the interconnection of pipes and valves.
An object of the present invention is to provide a device which enables a single individual to quickly, accurately and conveniently clamp a valve and a pipe in aligned relationship and in close proximity with one another so that they may be connected together by welding or the like.
In accordance with the present invention, a device for positioning a valve and a pipe in aligned relationship so that the same may be joined together by welding or the like, the valve and pipe each having a passage therethrough terminating in an opening and the openings being of substantially equal diameter, comprises an inner guide engageable with the valve and the pipe within the openings when the openings are in closely spaced relationship; an outer guide engageable with outer surfaces of the valve and pipe; means for moving said inner and outer guides towards and away from each other to grip the valve and pipe therebetween to hold the same in position for joining about the openings and for releasing the valve and pipe for removal of the device therefrom; and adjustment means coupled with said outer guide for enabling said outer guide to engage nonaligned valve and pipe outer surfaces.
The inner guide moves the valve and pipe passages into coaxial alignment when the inner and outer guides are moved together, and in a preferred embodiment the inner guide has a relatively long dimension or length and a relatively narrow dimension or width which enables insertion and removal of the guide into and from the valve and pipe passages through the space therebetween when its length extends generally perpendicular to the axes of the passages and enables engagement of the guide with the passage surfaces when its length extends generally along the axes of the passages.
The device according to its preferred embodiment includes an elongate rod having a screw-thread formed at least a portion thereof; an inner guide fastened to one end of the rod, said inner guide having a long dimension or length and a narrow dimension or width and being fastened to said one end of said rod generally medially of its length; an outer guide having a long dimension or length and a narrow dimension or width, said rod extending through a passage in said outer guide and said outer guide being movable along said rod; and adjustment means threaded onto said threaded portion of said rod to the side of said outer guide opposite from said inner guide and rotatably movable along said rod to move said outer guide along said rod towards said inner guide or to enable said outer guide to be moved along said rod away from said inner guide, said inner guide being in use positioned in the valve and pipe passages with its length extending generally along the axes of the passages and said outer guide being in use positioned to the exterior of the valve and pipe with its length extending generally along the length of the passages when the valve and pipe openings are in closely spaced relationship with the portion of said rod towards said inner guide then extending between the valve and the pipe, said adjustment means being operable to move said outer guide towards said inner guide to engage the outer surfaces of the valve and pipe with said outer guide and the passage surfaces with said inner guide to coaxially align the valve and pipe passages and to clamp the same in position for being joined, said adjustment means being operable after the valve and pipe are at least partially joined to unclamp the same and free said inner guide for rotation with said rod to extend its length generally perpendicular to the axes of the passages, the narrow dimension of said
inner guide being no greater or not substantially greater then the diameter of said rod thereat, whereby said inner guide may be withdrawn from said passages through the space between the openings, said outer guide
including compensating means for accommo
dating said outer guide to engage
nonaligned valve and pipe outer surfaces when the valve and pipe are clamped together.
To enable the outer guide to accommodate nonaligned valve and pipe outer surfaces, the adjustable means preferably includes a screwthreaded stud in a threaded passage through the outer guide towards one end thereof, with the stud extending generally perpendicular to the length and width of the outer guide and being rotatable to control the amount of extension of the stud beyond the guide. In this manner, in use of the device with valves and pipes having nonaligned outer surfaces, an end of the stud engages the outer surface of one of the valve and pipe, the opposite end of the outer guide engages the outer surface of the other of the valve and pipe, with the stud being rotatably adjusted to orient the outer guide generally perpendicular to the rod.
In one embodiment, the outer guide is elongate and has a longitudinal slot formed therethrough, the rod extends through the slot and has a screw-thread along a medial portion thereof normally positioned exterior of the valve and pipe, and the moving means includes an adjustment collar threaded onto the threaded portion and rotatable to move the outer guide along the rod towards the inner guide, or to enable the outer guide to be moved away from the inner guide. In another embodiment, the outer guide has a plurality of spaced passages formed therethrough longitudinally therealong, instead of a slot, and the rod is extendable through a selected one of the passages. In the case of either a slot or discrete passages, the same permits adjustment of the outer guide laterally of the rod.
The invention will be further described, by way of example with reference to the accompanying drawings, in which:
Figure 1 is a perspective view of a device, constructed in accordance with a preferred embodiment of the invention, for holding a valve and a pipe in alinged relationship for joining together by welding or the like;
Figure 2 is a slide elevation view, partly in cross section, showing the device holding a valve and a pipe;
Figure 3 is a side elevation view, partly in cross section, illustrating the manner in which the device may be removed from the pipe and valve after the same has been initially joined at spaced positions therearound, and
Figure 4 illustrates an alternative embodiment of a clamping member portion of the device.
Referring to the drawings which illustrate salient features of a preferred embodiment of the invention, and in particular to Fig. 1, a device 20 for holding and aligning valves and pipes to be joined together comprises an elongate rod 21 having a medial threaded section 22, a "T" handle 24 at an upper end thereof and a relatively narrow extension 26 at a lower end. An adjustment collar 28 is threaded about and rotatably movable along the threaded section of the rod by means of a pair of handles 30, and an elongate outer valve and pipe guide or clamp 32 receives the rod through a longitudinal slot 34 therein.
The slot is sized to permit the guide to move freely along and laterally of the threaded section 22, and an adjustment stud 36 having a slotted upper end 38 is threaded through the guide 32 towards one end thereof for movement with respect thereto by rotation. An elongate but narrow width wedge-shaped inner guide or clamp 40 is fastened medially of its length to the lower end of the extension 26, and a sleeve 41 between the collar 28 and the outer clamp 32 is freely slidable along the rod 21. The arrangement is such that, upon clockwise rotation of the adjustment collar 28 (as viewed from above), the pipe guides or clamps 32 and 40 are moved towards each other, and upon counterclockwise rotation, the guide 32 is free to move away from the guide 40.
In use, of the clamping device 20, and referring also to Fig. 2, to clamp or hold a valve 42 (only a cylindrical extension of an opening thereto being shown) and a pipe 44 in aligned relationship for joining together, the adjustment collar 28 is moved upwardly along the threaded section 22 towards the handle 24 to permit the outer and inner clamping guides 32 and 40 to be moved apart. The valve and pipe are then moved together to position the openings to their passages therein in closely spaced relationship about the extension 26, with the inner clamping guide 40 to the interior of the openings and passages and the outer clamp 32 to the exterior of the valve and pipe.To this end, when moved together adjacent ends of the valve and pipe about the openings define a space 46 therebetween which is relatively small, yet is greater then both the diameter of the extension 26 and the width of the inner clamp 40.
At this point the passages in and openings to the valve and pipe are only roughly aligned with one another. To coaxially align the same and secure the valve and pipe against movement in the closely spaced relationship so that they may be joined by welding or the like, the adjustment collar 28 is rotated clockwise to move the outer clamping guide 32 towards the inner guide 40. At the same time, the adjustment stud 36 may be rotated an appropriate amount within the outer guide, so that with continued movement of the guides together, the inner guide moves against surfaces of the valve and pipe passages and engages the same by knurled areas 48 on a curved upper surface thereof, and the outer guide is oriented generally perpendicular to the rod 21 and parallel the pipe and valve passages (as controlled by the adjustment stud 36), with a leftward end thereof (as viewed in Fig. 2) engaging the outer surface of the valve and the lower end of the adjustment stud engaging the outer surface of the pipe. The slot 34 in the outer guide accommodates lateral movement of the same on the rod, so that the guide and stud may be engaged with selected outer portions of the valve and pipe.Upon complete tightening of the adjustment collar 28, the inner guide 40 moves the valve and pipe passages and openings into coaxial alignment, and with the outer guide clamps the same in the closely spaced aligned relationship.
Although as illustrated the end of the adjustment stud 36 engages the outer surface of the pipe 44, since for the arrangement shown the diameter of the pipe is less than that of the valve about its opening, it is understood that, if the diameter relationships were reversed, then orientation of the upper clamping guide 32 would be reversed and the adjustment sud would engage the outer surface of the valve. In any event, it should be appreciated that the adjustment stud permits accommodation of the outer clamping guide to nonaligned valve and pipe outer surfaces, so that the outer guide may always be maintained perpendicular to the rod 21 for secure and proper clamping. Obviously, if the outer valve and pipe surfaces were aligned, then the stud would merely by rotatably retracted, so that the upper guide would then contact both the valve and pipe.
Also, although only a single valve-pipe clamp 20 is illustrated and described, it is to be understood that alignment and clamping of the valve and pipe may advantageously be accomplished with use of two or more of the devices, for example two at 1 80' spacings around the valve and pipe or three at 1 20' spacings. The use of multiple clamping devices, of course, provides improved support for the valve and pipe and ensures that the space 46 between the same is maintained uniform around the entirety of the circumference of the adjacent portions of valve and pipe, whereby axial alignment of the openings and passages is ensured.
As previously stated, when the opening to the valve and pipe are moved together, the space 46 is maintained greater then both the diameter of the extension 26 and the width of the inner guide 40. Thus, in use of the device 20, the valve and pipe could first be moved together into approximate alignment to define the space 46, and the inner guide 40 positioned within the passages by first orienting it with its length extending perpendicular to the axes of the passages and within the plane of the space. The guide and extension 26 may be extended through the space to position the guide 40 in the passages, and the rod 21 rotated to turn the guide to whereat its length extends generally along the axes of the passages.Consequently, the pipe and valve may either be moved together about the clamping device, or they may be positioned in close proximity with each other and the device placed in engagement therewith.
With the valve and pipe firmly clamped in aligned relationship as shown in Fig. 2, they may be temporarily secured together, for example by tack welds 50 in the case where the valve and pipe are metal. To this end, the abutting ends of the valve and pipe advantageously are tapered to form a "V" shaped notch therebetween to accommodate welding material and facilitate joining. Where multiple clamping devices 20 are used to clamp the pipe and valve, a single tack weld positioned medially of each adjacent pair of devices is generally sufficient to temporarily secure the pipe and valve in their aligned orientation.
After tack welds have been made around abutting ends of the pipe and valve, as shown in Fig. 3 the clamping device or devices may readily be removed, with the tack welds then continuing to hold the valve and pipe together. Removal is accomplished simply by rotating the adjustment collar 28 counterclockwise to free the outer and inner clamping guides 32 and 40 for movement apart and out of clamping engagement with the valve and pipe. This enables the inner guide 40 to be rotated within the valve and pipe passages to a position perpendicular to the passages, whereupon the inner guide and extension 26 may them be withdrawn through the space.
Thereafter, and after all of the clamping devices have been removed, a continuous weld may be made around the entire circumference of the adjacent ends of the pipe and valve to close the space 42 and to seal and join the pipe and valve together.
Fig. 4 illustrates an alternative arrangement for an upper clamping guide for the device 20, and in particular an upper guide 32' which may be used in place of the guide 32.
The guide 32' has an adjustment stud 36 threaded therethrough towards an end thereof, and a plurality of passages 52 (three as shown) for selectively receiving the elongate rod 21 therein. The passages are of a size sufficient to permit free sliding movement of the guide along the rod and, as compared with the slot 34 in the guide 32, define discrete lateral positions for the clamping guide with respect to the rod 21. For the purpose, and to permit extension of the rod through a selected one of the passages, the handle 24 may be secured to the upper end of the rod by means of a fastener 54, whereby the handle is removable from the rod. Thus, with the handle removed from the rod, the adjustable collar 28 may be threaded off of the rod and the rod extended through a selected one of the passages 52.Thereafter, the adjustment collar 28 is again threaded onto the rod and the handle affixed to the upper end thereof.
The invention thus provides an improved device for conveniently and economically clamping together valves and pipes to enable the same to be joined by welding or the like, while simultaneously ensuring coaxial alignment of passages therein. By virtue of the ease of operation of the device, joining together of valves and pipes may be accomplished by a single individual and without need for elaborate or cumbersome exterior supports.
While embodiments of the invention have been described in detail, various modifications and other embodiments thereof may be devised by one skilled in the art without departing from the scope of the invention, as defined by the claims.
