Abstract
A gas valve assembly for use with a gas grill includes a t-shaped manifold with an inlet fluid port that branches out into a pair of valve ports. A pair of gas valves each have an outwardly extending neck that is received within the valve ports of the manifold. A stop means locates the valves a predetermined distance from one another to improve manufacturability. An anti-rotation means minimizes rotation between each valve and the manifold.
Description
- This application is a continuation of U.S. patent application Ser. No. 09/232,547 filed on Jan. 18, 1999, the disclosure of which is incorporated herein by reference.
- The present invention relates generally to a fluid fitting assembly, and more particularly, to a staked dual valve and manifold system.
- Contemporary outdoor gas grills often utilize dual gas burners that are controlled by a common dual gas valve assembly. A typical dual gas valve assembly has a single feed supply line that delivers gas to a pair of valves which in turn selectively supplies gas to the individual burners in the gas grill. Conventional methods of connecting the gas supply line to the valves include using a manifold fitting with a plurality of ports. The ports are often threaded internally or externally, in order to enhance connectability of the gas inlet line and the valves.
- The problem with conventional threaded pipe connections is that they are slow to assemble in a high-speed manufacturing environment. Further, they require additional manufacturing steps including cutting threads, either internally or externally, into the fitting or the manifold. Also, the pipe or member that is to be connected to the manifold must be threaded. Such designs increase the per unit cost and require special machines for production.
- Other problems with conventional threaded pipe connections for gas valve assemblies is the difficulty of obtaining the proper alignment of the two valves relative to the face plate of the gas grill. Typical face plates for gas grills include prepunched holes that allow the valve stems to extend therethrough. Thus, the valve stems must be concentric with the prepunched holes in the face plate. Failure to maintain such alignment creates a visually displeasing appearance. It has been problematic to maintain the distal relationship between the valve stems when the gas manifold assembly is threaded. This in part because the angular displacement caused by threading the parts together creates a variable in the manufacturing process. It is preferred to remove this variable from the manufacturing process in order to improve product quality. This can be accomplished in part by maintaining the distal relationship of the centerline of each valve stem by creating a stop between the valves and the manifold.
- Therefore, there is a need to provide a dual gas valve assembly that either eliminates or minimizes the number of threaded connections, has enhanced manufacturability, can be formed in a minimal number of steps, can be mass produced, yet still produce a gas tight connection by way of a threadless mechanical stake. There is also a need for an assembly that has an alignment feature for promptly and accurately joining a valve to a manifold in high speed manufacturing environments.
- Accordingly, it is an object of the present invention to provide a dual valve and manifold system that overcomes the problems mentioned above. Such a manifold system should be simple in design, minimize the number of operations required by an operator to create such an assembly, and minimize the number of tools that are required to perform such an operation while still being capable of providing a mechanical joint with significant joint integrity.
- One of the preferred forms of the present invention provides as one of its aspects, a fitting having a fluid delivery bore connected to a central chamber, a first elongated section extending from the central chamber, a second elongated section extending from the central chamber, and a crimped portion located at an end of the elongated sections for securing the fitting to first and second control valves. A first control valve has a main body with a central fluid passage. The first control valve further has an outwardly extending member with an internal fluid passage. A second control valve with a main body has a central fluid passage. The second valve further has a member with an internal fluid passage and a member which extends outwardly from the main body.
- For a more complete understanding of the dual valve assembly, reference is made to the following detailed description and accompanying drawings in which the presently preferred embodiments of the invention are illustrated by way of example. Because the invention may take on several forms without departing from the spirit or essential characteristics thereof, it is expressly understood that the drawings are for purposes of illustration and description only, and are not intended as a definition of the limits of the invention. Throughout the following description and drawings, identical reference numbers refer to the same component throughout the several views.

- A dual
gas valve assembly 10 is shown in FIGS. 1 through 3. Thevalve assembly 10 is comprised of amanifold 12 and a pair ofcontrol valves manifold 12 and thecontrol valves - The
manifold 12 is preferably T-shaped and is made of malleable metal in order to allow it to deform as needed. An inlet side of themanifold 12 hasexternal threads 18 and an internalfluid delivery passageway 20. Acentral chamber 22 delivers fluid, such as gas, to alarge bore 24 and into a pair offluid passages 26. Thefluid passages 26 are defined in part by a pair of outwardly extendingelongated members 28 which extend in a direction that is normal to theinlet 20. Themanifold 12 is symmetrical about a center axis which extends throughinlet 20. Eachfluid passage 26 has a chamferedcorner 29. - Each
control valve control valve 14 will follow. With reference to FIGS. 1 through 3,control valve 14 includes avalve stem 30, amain body 32 and acover plate 34 that clamps thevalve stem 30 to themain body 32 viafasteners 36. Themain body 32 has a longitudinally extendingfluid passage 38 and an outwardly extendingmember 40 having afluid passage 42. The outwardly extendingmember 40 is preferably a continuous extension of themain body 32, both of which are preferably made of metal by casting or forging. Themember 40 has aneck 44 and ashoulder 46 that mates with thechamfered edge 29 to create astop 43 and seat. This self aligning feature allows thevalve 14 to be located relative to themanifold 12 in a precise position very fast compared to conventional threaded methods of assembly. When bothvalves manifold 12, the valves are located at a predetermined distal relationship to one another. This will ensure that the valve stems are properly centered within the holes in the face plate of the gas grill. - As shown in FIGS. 2 and 3, a portion of the
neck 44 has flattenedsections 48 and asemi-circular section 50 with thefluid passage 42 extending therethrough. Theflattened section 48 provides an anti-rotation feature to minimize rotation of thecontrol valve 14 relative to themanifold 12. Rotation of the valve relative to the manifold is further minimized by displacing a portion of the fitting within arecess 52 in thecontrol valve 14 near theflattened section 48. This is accomplished in part by theends 54 of theelongated members 28 being crimped which also forms a tight seal between themanifold 12 and thecontrol valve 14. The crimping action further forces theend 46 of the valve against theshoulder 56 of the manifold. Thus, a plurality of seals are created by virtue of this gas valve assembly. - With reference to FIGS. 4 and 5, an alternative embodiment
gas valve assembly 100 is illustrated. The primary difference between thegas valve assembly 100 and thegas valve assembly 10 as shown in FIG. 1 is that thealternative assembly 100 does not have a flattened neck extending from the valve body. Instead, the neck is substantially in circular form and is crimped around its entire perimeter by the ends of the manifold. - The primary components of the
gas valve assembly 100 includes the T-shapedmanifold 12 and a pair ofcontrol valves control valve 102 will be presented.Control valve 102 includes avalve stem 30, amain body 32, acover 34, and a pair offasteners 36. The main body has acentral fluid passage 38 and an outwardly extendingmember 40 at a substantially right angle to the fluid passage. The configuration of theneck 106 is substantially circular in cross section and is elongated with a smoothexterior surface 108. Theneck 106 further has afirst shoulder 110 and asecond shoulder 112 at distal ends. When assembled, theshoulder 112 abuts againstshoulder 56 of the manifold to create a seal therebetween once theend 54 is crimped. Thecrimped end 54 extends around the entire circumference of thefirst shoulder 110 which acts as a securing means to lock together the manifold 12 and thecontrol valve 102. The resulting assembly createsseals - During operation, fluid enters
inlet passageway 20, then flows tocentral chamber 22, is then split bi-directionally intofluid passages 42 and is finally directed into the fluid chamber orpassage 38 of thevalves outlet 120. The rate of flow of gas through thecontrol valve 102 is controlled in part by adjusting thearm 30 and its inter-connected components (not disclosed herein). - With reference to FIGS. 6 and 7, a second alternative embodiment gas valve and
manifold assembly 200 is disclosed which employs many of the components of the FIG. 1 dualvalve gas assembly 10. However, an O-ring has been added to provide an extra seal and the fitting now has a mounting pad. It will be appreciated that the embodiments depicted in FIGS. 1-5 could include this unique seal and mounting pad. Thegas valve assembly 200 includescontrol valves manifold fitting 202 with a mounting pad and an O-ring 204. Thecontrol valves control valve 14 will be presented. -
Control valve 14 includes agroove 206 near the outer end of theneck 208. The O-ring 204 is seated within thegroove 206 and provides yet a fourthadditional seal 210 between themanifold fitting 202 and the valve assembly. The outer ends 54 of the fitting 202 are crimped to encapsulate the neck within thepassage 26. Thus, seals 114, 116, 118 and 210 are created once theassembly 200 is completed. Thegas valve assembly 200 further employs the same anti-rotation feature because theneck 208 has the same flattenedsection 48 andsemi-circular section 50 as disclosed in FIG. 2. - The fitting202 has an
inlet 212 with an exterior having a hose barb type configuration, a pair of outwardly extendingmembers 214 and amounting pad 216. The mountingpad 216 extends outwardly from themembers 214 and has a flattenedsurface 218 with a pair ofholes 220 for securing theassembly 200 to a front panel on a gas grill. It will be appreciated that the fitting can be configured differently to accommodate various types of mounting arrangements. - It will also be appreciated that other configurations of the anti-rotation components are permissibly within the scope of this invention. The configuration illustrated in FIG. 2 is exemplary in nature and is not intended to limit the scope of this invention.
