Description
- The present application is a continuation application of U.S. patent application Ser. No. 14/207,783, filed Mar. 13, 2014, which claims priority to and the benefit of U.S. Provisional Patent Application Ser. No, 61/785,606, filed Mar. 14, 2013, both of which are hereby incorporated by reference in their entirety.
- 1. Field of the Invention
- The present invention relates generally to valve assemblies and, more particularly to, a valve assembly including dual flanges offset relative to each other.
- 2. Description of the Related Art
- Valve assemblies, such as those for transferring fluid, are known in the art. One type of valve assembly is an internal valve. Internal valves are often mounted to a sump of a storage tank on a vehicle such as a bobtail truck or other types of transport trucks. Beneath the internal valve, a pump is often attached to convey liquid out of the storage tank. See, for example, the arrangement of the
internal valve 10 and pump 12 inFIG. 1 . As shown, thepump 12 is attached directly beneath theinternal valve 10 vertically in line with theinternal valve 10. - One disadvantage of these pumps is that they are often large and cumbersome and, due to space constraints beneath the storage tank, often interfere with parts of a chassis of the truck. As a result, the
pump 12 installation requires straddling across a rail 14 of the chassis of the truck. When a width between parallel rails on trucks is like that shown inFIG. 1 , pump installation is difficult. As a result, there is a need in the art to provide a new valve assembly that addresses these space constraints to facilitate installations. - Accordingly, the present invention provides a valve assembly for mounting a pump to a storage tank on a vehicle. The valve assembly includes a valve body having an upper flange, a lower flange, and a wall extending axially between the upper flange and the lower flange. The lower flange is offset by the wall relative to the upper flange to facilitate installation of the pump on the vehicle.
- One advantage of the present invention is that a new valve assembly is provided between a storage tank mounted to a vehicle and a pump. Another advantage of the present invention is that the valve assembly includes dual flanges that are offset relative to each other and allow positioning of the pump away from a rail of the vehicle, the rail no longer interfering with the pump, in contrast to the prior art installations. Yet another advantage of the present invention is that the valve assembly provides flexibility to adjust the amount of offset, resulting in installations of the valve assembly to accommodate variations in different chassis sizes, shapes, styles, etc. of the particular vehicle to which the storage tank is mounted.
- Other features and advantages of the present invention will be readily appreciated, as the same becomes better understood, after reading the subsequent description taken in conjunction with the accompanying drawings.

FIG. 7 is a partial perspective view of the valve assembly ofFIG. 5 . - Referring to the Figures and in particular
FIGS. 2 through 6 , wherein like numerals indicate like or corresponding parts throughout the several views, one embodiment of avalve assembly 20, according to the present invention, is shown. Thevalve assembly 20 is utilized to manipulate fluid transfer. Thevalve assembly 20 is of an internal valve type. It should be appreciated that the fluid handled by thevalve assembly 20 can be liquid petroleum gas (LP-Gas), anhydrous ammonia (NH3) or any other suitable fluid. - Referring to
FIG. 2 , thevalve assembly 20 is typically mounted to astorage tank 22 storing the fluid. In the embodiment illustrated, thevalve assembly 20 is mounted to anoutlet sump 24 integral with the storage tank 22 (here thestorage tank 22 is shown mounted on a vehicle such as a transport truck, in particular a bobtail truck). Thesump 24 is a downwardly extending neck that surrounds an outlet of thestorage tank 22. Thevalve assembly 20 is configured to be mounted to thesump 24 to facilitate withdrawal of fluid from thestorage tank 22. Thevalve assembly 20 is configured for receiving apump 26 for withdrawing fluid from thestorage tank 22. Thepump 26 is mounted beneath and to thevalve assembly 20. Thepump 26 is of a liquid pump type for withdrawing fluid from thestorage tank 22 through thevalve assembly 20. It should be appreciated that thevalve assembly 20 is used for mounting thepump 26 to thestorage tank 22 on the vehicle. - The
valve assembly 20 includes avalve body 28 having anupper flange 30 and alower flange 32. Thevalve body 28 includes awall 31 extending between theflanges upper flange 30 is generally circular in shape. Theupper flange 30 is sized to mount to thesump 24. Theupper flange 30 defines a plurality of circumferentially spacedthroughbores 30 a for receiving a plurality of threadedfasteners 30 b. In the embodiment illustrated, theupper flange 30 has eight (8)throughbores 30 a circumferentially spaced thereabout. The threadedfasteners 30 b are first threaded into corresponding threaded bores (not shown) in thesump 24. Theupper flange 30 is then fitted to thesump 24 by positioning thethroughbores 30 a over the threadedfasteners 30 b and securingnuts 30 c onto the threadedfasteners 30 b as illustrated inFIG. 2 . Thethroughbores 30 a are internally smooth and include bushings (not shown) disposed therein for slidably receiving the threadedshafts 30 b. In some embodiments, a seal or gasket (not shown) is first positioned between thesump 24 and theupper flange 30. - The
lower flange 32 is spaced axially from theupper flange 30. Thelower flange 32 is generally parallel toupper flange 30. Thelower flange 32 is generally circular in shape. Thelower flange 32 defines a plurality of circumferentially spaced and threadedbores 32 a (FIG. 6 ) for receiving a plurality of threadedfasteners 32 b. In the embodiment illustrated, thelower flange 32 has eight (8) threaded bores 32 a spaced circumferentially thereabout. Once theupper flange 30 is attached to thesump 24, thepump 26 is attached to thelower flange 32. The threadedfasteners 32 b are threaded into the threaded bores 32 a of thelower flange 32. Smooth throughbores (not shown) of apump flange 25 of thepump 26 are positioned over the threadedfasteners 32 b. Thepump flange 25 is held in place bynuts 32 c fastened to the threadedfasteners 32 b. - The
lower flange 32 is vertically or radially offset fromupper flange 30. As a result, an angled portion of thewall 31 is oriented at an acute angle with respect to thelower flange 32. In some embodiments, the acute angle is greater than 0 degrees, but less than 90 degrees, more preferably from about 10 degrees to about 80 degrees, and most preferably from about 40 degrees to about 75 degrees. The axial distance between anupper surface 30 d of theupper flange 30 and anupper surface 32 d of thelower flange 32 is from about 4 inches to about 24 inches, more preferably from about 4 inches to about 20 inches, and most preferably from about 4 inches to about 12 inches. - In the embodiment illustrated, the
lower flange 32 has a maximum offset from about 0.5 inches to about 4.0 inches relative to theupper flange 30. More preferably, thelower flange 32 has a maximum offset from about 1.0 inches to about 3.0 inches, and in the particular embodiment illustrated, thelower flange 32 has a maximum offset from about 2.0 inches relative to theupper flange 30. - It should be appreciated that the offset is based on the particular horizontal point of view taken of the
valve assembly 20. For instance, referring toFIGS. 3 and 4 , the same horizontal point of view is shown for viewing thevalve assembly 20, however, thevalve assembly 20 is shown in different rotational positions about a central axis C. As a result, the offset is only visible inFIG. 4 from the particular point of view shown. InFIG. 3 , thevalve assembly 20 is rotated 90 degrees with respect toFIG. 4 so that the offset is positioned to be in line with the point of view, which makes it unperceivable.FIGS. 3A and 4A show overhead views of this same principle with the horizontal point of view indicated by an arrow A. - During installation, a user can control the amount of offset to apply. For instance, in one embodiment, the offset is reduced by 10% to 50% by rotating the
valve assembly 20 one throughbore 30 a in either direction when attaching thevalve assembly 20 to thesump 24. In some embodiments, when thevalve assembly 20 is rotated by one throughbore 30 a (out of eight) in either direction, the offset is reduced from 2 inches to 1.25 inches with respect to the same horizontal point of view. The variation in offset (shown by double arrows D) inFIGS. 4A and 4B illustrate this concept. InFIG. 4B , the perceived offset is less than the perceived offset inFIG. 4A due to the amount of rotation of thevalve assembly 20 about the central axis C. It should be appreciated that the perceived offset is based on the point of view represented by the arrow A inFIGS. 4A and 4B . - With the flexibility to adjust the offset, installations of the
valve assembly 20 can be made easier to accommodate variations in different chassis sizes, shapes, styles, etc. of the particular transport truck to which thestorage tank 22 is mounted. As illustrated inFIG. 2 , by positioning the offset away from arail 29 of the vehicle, therail 29 no longer interferes with thepump 26, in contrast to the prior art installation shown inFIG. 1 . - Referring to
FIGS. 5 and 6 , thevalve assembly 20 includes amesh cage 34 disposed over and covering anupper portion 31 a of thewall 31 of thevalve body 28 that extends upwardly fromupper flange 30. Themesh cage 34 is configured for installation inside thestorage tank 22. Thewall 31 defines acavity 40. Thevalve assembly 20 includes amain valve member 42 partially disposed in thecavity 40. Generally, themain valve member 42 controls fluid flow through thevalve assembly 20 between thetank 22 and thepump 26. Themain valve member 42 is moveable between an open position and a closed position. In the open position, themain valve member 42 allows fluid flow through thevalve assembly 20. In the closed position, themain valve member 42 prevents fluid flow through thevalve assembly 20. Generally, themain valve member 42 moves along the central axis C. Themain valve member 42 may be known in the art as a poppet valve. Further details of themain valve member 42, its operation, and the remaining internal components of thevalve assembly 20 are disclosed in U.S. patent application Ser. No. 13/744,599, entitled “Valve Assembly and Method”, the disclosure of which is hereby incorporated by reference. - The
valve assembly 20 also includes an actuator, generally indicated at 50, extending through agland port 51 integral with thewall 31. Theactuator 50 moves themain valve member 42 between the open position and the closed position. Thegland port 51 defines abore 52. In one embodiment, theactuator 50 includes ashaft 56 extending through thebore 52 and into thecavity 40 of thevalve body 28. Theshaft 56 is rotatable in thebore 52 about a pivot axis P between a plurality of operational positions. It should be appreciated that theshaft 56 is secured in thebore 52 by afastener 54 such as a nut threadably engaging thebore 52. - The
actuator 50, which may include a pneumatic or rotary type actuator, includes acam 58 coupled to theshaft 56 for engaging apilot valve member 59 coupled to themain valve member 42. Thepilot valve member 59 includes apilot valve stem 60 and thecam 58 engages thepilot valve stem 60. Thepilot valve member 59 configuration is conventional for actuating themain valve member 42 of internal valves, as disclosed in U.S. patent application Ser. No. 13/744,599, entitled “Valve Assembly and Method”, the disclosure of which is hereby incorporated by reference. - Referring to
FIG. 7 , thevalve assembly 20 further includes a plurality of thegland ports 51 definingbores 52 provided for selectively receiving theshaft 56 of theactuator 50. In one embodiment, threegland ports 51 are spaced circumferentially about thewall 31 of thevalve assembly 20. Thegland ports 51 may be provided at 90 degree intervals about thevalve assembly 20. The spacing of thegland ports 51 may be larger or smaller. With themultiple gland ports 51, flexibility with installation is increased as compared to conventional internal valves. For instance, if thevalve assembly 20 is installed in one rotational position relative to thesump 24, a first of thegland ports 51 can be used to receive theshaft 56 of theactuator 50, while the other twogland ports 51 are plugged with threaded plugs 62. In some embodiments, when thesame valve assembly 20 is rotated to a different rotational position, a second or third of thegland ports 51 could be used with theother gland ports 51 plugged with the threaded plugs 62 as illustrated inFIG. 7 . - Embodiments of the present invention have been described in an illustrative manner. It is to be understood that the terminology, which has been used, is intended to be in the nature of words of description rather than of limitation.
- Many modifications and variations of the present invention are possible in light of the above teachings. Therefore, the present invention may be practiced other than as specifically described.
