Technical Field

[0004] The present invention relates to a valve installation adaptor kit. The valve installation adaptor kit may be used in the installation of a valve, i.e. to install a valve, in a plumbing installation with a water heater.

Background Art

[0005] Any discussion of background art, any reference to a document and any reference to information that is known, which is contained in this specification, is provided only for the purpose of facilitating an understanding of the background art to the present invention, and is not an acknowledgement or admission that any of that material forms part of the common general knowledge in Australia or any other country as at the priority date of the application in relation to which this specification has been filed.

[0006] It is often the case that valves, of one type or another, must be connected into plumbing installations. Ball valves or isolation valves, thermostatic mixing valves, temperature control valves, pressure limiting valves, and pressure reducing valves are just a few examples of valves that are used in plumbing installations.

[0007] It is also often the case that the connections, in the plumbing installations, to which valves are to be connected, are of different sizes and/or different types. The size of a connection refers to the diameter of the connection. The type of connection refers, for example, to whether the connection is a screw thread (and also whether it is a male screw thread or a female screw thread) or some other type of connection, e.g. the connection may be of a type that requires a tube to be connected by a flared connection or a compression connection.

[0008] By way of an example so as to see the ramifications of these variations in practice, reference is now made to the use of a specific type of valve in a specific plumbing installation. Regulatory requirements in Australia, at least, specify that plumbing installations for water heaters require an isolation valve to be connected on the water inlet side of the water heater. This is typically achieved by a plumber connecting the outlet of a ball valve to the water inlet of the water heater and the inlet of the ball valve to the tube that delivers the water to the water inlet of the water heater. The tube is typically a copper tube. The copper tube is typically connected to the ball valve by a compression connection or flared connection and the ball valve is screw threadedly connected to the water heater inlet by a loose nut on the ball valve.

[0009] When a gas connection is required to deliver gas to the water heater, regulatory requirements in Australia, at least, specify that an isolation valve is required to be connected on the gas inlet side of the water heater. This is typically achieved by a plumber connecting the outlet of a ball valve to the water heater gas inlet and the inlet of the ball valve to the tube that delivers the gas to the water heater. The tube is typically a copper tube. The copper tube is typically connected to the ball valve by a flared connection and the ball valve is connected to the water heater gas inlet by a loose nut on the ball valve.

[0010] The sizes of the tubes, that can be connected into such hot water heater plumbing installations, vary. Similarly, the sizes of the connections at the inlets to the water heaters, which are used in such plumbing installations, vary. By way of example, two typical sizes may be, say, ¾ inch and1/2 inch. In addition, the type of connection at the hot water heater could potentially also vary from one hot water heater manufacturer to another, or vary from one jurisdiction to another, e.g. from one country to another. Because of these different sizes and potentially different types of connections, currently, the only options available to the plumbing merchant and the plumber are a range of purpose built ball valves and outlet fittings with fixed inlet and outlet connections of different sizes and potentially different types of connections. This means that plumbing merchants have to stock many ball valve products (which are substantially the same in structure and function, but have different sizes of connections and possibly different types of connections, e.g. male or female) on their shelves. Similarly, plumbers must carry these different ball valves in their vehicles to cater for different instantaneous water heater inlet and outlet configurations and installation requirements.

[0011] In view of the different sizes of connections and the different types of connections that may be required, it is readily apparent that there are a large number of permutations of ball valve connection size and connection type combinations.

[0012] When the wide range of different valves types is added to the mix, there becomes a bewildering range of valve type, connection size and connection type combinations. Consequently, the only options available to the plumbing merchant and the plumber are a range of purpose built valves and or fittings with fixed inlet and outlet connections. This means that they both have to carry extra products on the shelf and in their vehicles to cater for differing inlet and outlet configurations and installation requirements.

[0013] It would be advantageous, to both the plumbing merchant and the plumber, if the number of different valves that are required could be reduced, whilst the versatility of meeting the various different valve inlet and outlet connection configurations and installation requirements could still be maintained.

Description of Embodiments

[0063] The valve installation adaptor kit of the present invention includes components such that installation of a valve may be carried out for the application, or applications, required. In a comprehensive form, the valve installation adaptor kit may include components that enable connection of a valve into a plumbing installation with any sized connection or type of connection that may be required. For example, a valve installation adaptor kit may include all of the components described in connection with the embodiments shown in Figures 4 to 11.

[0064] Figure 1 shows a schematic side elevation view of the components of a valve installation adaptor kit in accordance with an aspect of the present invention. Central to the valve installation adaptor kit of the present invention, shown in Figure 1, is the valve unit, identified by reference numeral 10 in the drawings. The valve unit 10 comprises a housing 12, an inlet 14, an outlet 16 and the operational components (not shown) of the valve unit 10. The operational components of the valve unit 10 are contained in the housing 12. The operational components of the valve unit 10 are provided between the inlet 14 and the outlet 16. The form and structure of the operational components of the valve unit 10 will be determined by the nature of the valve unit 10, e.g. it may function as a ball valve or isolation valve, thermostatic mixing valve, temperature control valve, pressure limiting valve, and pressure reducing valve, etc. However, the actual nature of the valve unit 10, as regards the form and structure of its operational components, does not form part of the present invention and the operational components may be of conventional form and structure.

[0065] A passage extends through the housing 12 of the valve unit 10 between the inlet 14 and the outlet 16.

[0066] Connection means is provided at the inlet 14 and the outlet 16. The connection means comprises at least one screw thread at the inlet 14 or the outlet 16.

[0067] The valve installation adaptor kit shown in Figure 1 also includes components that may be used to connect the valve unit 10 into a plumbing installation; these components are shown generally by reference numbers 18 and adjacent the inlet 14 and the outlet 16, respectively.

[0068] Figures 2 and 3 show a first arrangement of basic components of a valve installation adaptor kit in accordance with the present invention.

[0069] In Figures 2 and 3, the valve unit 10 is provided with a screw thread 22 at the inlet 14 and a screw thread 24 at the outlet 16. Both screw threads 22 and 24 are female screw threads.

[0070] However, as an alternative to both screw threads 22 and 24 being female screw threads, both of the screw threads 22 and 24 could be male screw threads, or one of the screw threads 22 or 24 could be a female screw thread and the other a male screw thread. Figures 12 to 23 of the drawings show embodiments in which male screw threads are used, as will be further herein described.

[0071] Figures 2 and 3 show a respective nut 26, adjacent the inlet 14 and the outlet 16, having a male (i.e. external) screw thread 28 that can engage with the female screw threads 22 and 24. The male screw thread 28 of a nut 26 is able to engage with a female screw thread 22 of the housing 12. An 0-ring 30 is provided at the end of the male screw thread 28 of a nut 26 such that it is sandwiched between the housing 12 and a nut 26 when a nut 26 is screwed into the housing 12 so as to form a seal there between. The nut 26 is also provided with a female (i.e. internal screw thread 28a.

[0072] The valve installation adaptor kit includes means to adapt, i.e. adaptor means, the valve unit 10 to be connected into the plumbing installation with a variety of options for connection size and connection type.

[0073] The valve unit 10 may be provided with the adaptor means and/or the adaptor means may comprise one or more separate components of the valve installation adaptor kit that function as adaptors to permit the valve unit 10 to be connected into the plumbing installation.

[0074] The adaptor means may include one or more of the following: a tube adaptor insert (tube stop adaptor) that is insertable, or receivable, into the housing 12 through the inlet 14 of the valve unit 10; a tube support adaptor (reducer) receivable in the nut 26; and, a reducing screw thread adaptor that is engageable with a loose nut. The various adaptor means are further described herein.

[0075] A first annular ledge, or annular surface, 32 is provided inside the housing 12, at the end of the female screw thread 22 that is spaced from the inlet 14. The annular ledge 32 faces toward the inlet 14. The annular ledge 32 is provided as a step in the wall of the housing 12 such that the diameter of the passage 34, that extends through the housing 12 of the valve unit 10 between the inlet 14 and the outlet 16, is greater on the inlet side 36 of annular ledge 32 than on the outlet side 38 of the annular ledge 32. That is to say, there is a reduction in the diameter of the passage 34 at the annular ledge 32, in the direction from the inlet 14 to the outlet 16.

[0076] An annular bevel, or tapered, surface 40 is provided in the wall of the housing 12 adjacent the annular ledge 32. The annular bevel surface 40 is tapered inwardly from the direction of the inlet 14 to the outlet 16.

[0077] A second annular ledge, or annular surface, 42 is provided inside the housing 12, on the outlet side 38 of the annular ledge 32 and the annular bevel , and spaced from the annular bevel surface 40.

[0078] The nut 26a is provided with an annular bevel surface 46 at its end 48 that is inserted into the inlet 14, as will be further described herein.

[0079] Figures 4 to 11

[0080] Figures 4 to 11 show various embodiments of components that may be used to connect the inlet 14 into a plumbing installation. The outlet 16 may be connected into the plumbing installation using the same embodiment of components as used to connect the inlet 14, or any of the other embodiments shown in Figures 4 to 11. The nut 26a shown in Figures 4 to 11 is substantially similar to the nut shown in Figures 2 and 3, except that its is not provided with the female screw thread 28a.

[0081] First Tube Size - Compression Connection

[0082] In Figures 4 and 5, there is shown a first embodiment of components, generally shown by reference numeral 1, of a valve installation adaptor kit of the present invention. The components la are used for an installation using a compression connection to connect a tube (not shown) to the valve unit 10 to thereby connect the inlet 14 of the valve unit 10 into a plumbing installation.

[0083] The components 1 include a valve unit 10 and nut 26a, which have been herein before described, and an olive 44. The olive 44 is of the size required for use with the tube that will be connected to the valve unit 10.

[0084] In use, to connect the inlet 14 into the plumbing installation using the components 1, the tube is passed through the nut 26a and the then the olive 44, and the tube is inserted into the inlet 14. The end of the tube abuts against the second annular ledge 42 and the male screw thread 28 of the nut 26a is engaged with the female screw thread 22 of the housing 12. Tightening the screw threads 28 and 22 crushes the olive 44 between the annular bevel surface 40 of the housing 12 and the annular bevel surface 46 of the nut 26a and against the tube. This forms a compression connection.

[0085] Second Tube Size - Compression Connection

[0086] In Figures 6 and 7, there is shown a second embodiment of components, generally shown by reference numeral 2, of a valve installation adaptor kit of the present invention. The components 2 are used for an installation using a compression connection to connect a tube (not shown) to the valve unit 10 to thereby connect the inlet 14 of the valve unit 10 into a plumbing installation. The components 2 are used for a plumbing installation using a compression connection to connect a tube to the valve unit 10, when a tube of smaller diameter needs to be connected to the valve unit 10.

[0087] The components 2 include a valve unit 10 and nut 26a, which have been herein before described, a (compression) tube adaptor insert 50 (which functions as a tube stop), a tube support adaptor 52 and an olive 54.

[0088] The tube adaptor insert 50 is substantially in the form of a ring or cylinder. An 0-ring 56 is provided in a groove at the outer circumferential surface of the tube adaptor insert 50. An annular bevel surface 58 is provided at one (first) side face 60 of the tube adaptor insert 50. An annular ledge, or annular surface, 62 is provided at the other (second) side face 64 of the tube adaptor insert 50.

[0089] The tube support adaptor 52 is of substantially ring or cylindrical form. An 0-ring 66 is provided in a groove at the outer circumferential surface of the tube support adaptor 52. An annular bevel surface 68 is provided at the end 70 of the tube support adaptor 52 that is inserted into the inlet 14 of the housing 12. The end 70 is flared outwardly such that a tapered surface 72 is formed.

[0090] The olive 54 is of the size required for use with the tube that will be connected to the valve unit 10. The olive 54 is of a smaller diameter than the olive 44, since the tube has a smaller diameter.

[0091] In use, to connect the inlet 14 into the plumbing installation using the components 2, the tube is passed through the nut 26a and then the tube support adaptor 52, the olive 54 and then the tube adaptor insert 50, and the tube is inserted into the inlet 14. The end of the tube abuts against the annular ledge 62 of the tube adaptor insert 50. The tube adaptor insert 50 abuts against the second annular ledge 42 in the housing 12. The male screw thread 28 of the nut 26a is engaged with the female screw thread 22 of the housing 12. Tightening the screw threads 28 and 22 crushes the olive 54 between the annular bevel surface 58 of the tube adaptor insert 50 and the annular bevel surface 68 of the tube support adaptor 52. The end 70 ofthe tube support adaptor 52 abuts against the annular ledge 32 inside the housing 12. The tapered surface 72 of the tube support adaptor 52 abuts the annular bevel surface 46 of the nut 26a. This forms a compression connection.

[0092] First Tube Size - Flared Connection

[0093] In Figures 8 and 9, there is shown a third embodiment of components, generally shown by reference numeral 3, of a valve installation adaptor kit of the present invention. The components 3 are used for an installation using a flared tube connection to connect a tube (not shown) to the valve unit 10 to thereby connect the inlet 14 of the valve unit 10 into a plumbing installation.

[0094] The components 3 include a valve unit 10 and nut 26a, which have been herein before described, and a (flared) tube adaptor insert 74 (which functions as a tube stop).

[0095] The tube adaptor insert 74 has an end 76 that abuts with the second annular ledge 42 when the tube adaptor insert 74 is inserted into the housing 12 through the inlet 14.

[0096] An annular extension 78 is provided at the outer circumferential surface of the tube adaptor insert 74. An 0-ring 80 is provided in a groove at the outermost circumferential surface of the flared tube adaptor insert 74 adjacent the surface of the annular extension 78 that faces the end 76. The other end 82 of the tube adaptor insert 74 is provided with a bevel, or tapered, surface 84.

[0097] In use, to connect the inlet 14 into the plumbing installation using the components 3, the tube adaptor insert 74 is inserted into the inlet 14 until the end 76 of the tube adaptor insert 74 abuts against the second annular ledge 42 inside the housing 12 and the annular extension 78 abuts against the annular ledge 32. The O-ring 80 provides a seal inside the housing 12, at this location, between the wall of the housing 12 and the outer surface of the tube adaptor insert 74. The tube is inserted through the nut 26a. A flare is formed at the end of the tube. The flare may be formed in a conventional way. The flared end of the tube is positioned to abut the bevel surface 84 of the tube adaptor insert 74, which is now positioned inside the housing 12 as previously herein described. The male screw thread 28 of the nut 26a is engaged with the female screw thread 22 of the housing 12. As the screw threads 22 and 28 are tightened, the flared end of the tube is tightly gripped, in a vice-like manner, between the annular bevel surface 46 of the nut 26a and the bevel surface 84 of the tube adaptor insert 74. This forms a flared (tube) connection.

[0098] Second Tube Size - Flared Connection

[0099] In Figures 10 and 11, there is shown a fourth embodiment of components, generally shown by reference numeral 4, of a valve installation adaptor kit of the present invention. The components 4 are used for an installation using a flared connection to connect a tube (not shown) to the valve unit 10 to thereby connect the inlet 14 of the valve unit 10 into a plumbing installation. The components 4 are used for a plumbing installation using a flared tube connection to connect a tube to the valve unit 10, when a tube having a smaller diameter needs to be connected to the valve unit 10.

[00100] The components 4 include a valve unit 10 and nut 26a, which have been herein before described, a (flared) tube adaptor insert 86 (which functions as a tube stop) and tube support adaptor 88.

[00101] The tube adaptor insert 86 has an 0-ring 90 provided in a groove provided in an annular extension 92 at the outer circumferential surface of the tube adaptor insert 86. The annular extension 92 is provided at the end 94 of the tube adaptor insert 86 that abuts with the second annular ledge 42 when the tube adaptor insert 86 is inserted into the housing 12 through the inlet 14. The other end 96 of the tube adaptor insert 86 is provided with a bevel, or tapered, surface 98.

[00102] An 0-ring 100 is provided in a groove at the outer circumferential surface of the tube support adaptor 88. An annular bevel surface 102 is provided at the end 104 of the tube support adaptor 88 that is inserted into the inlet 14. The end 104 is flared outwardly such that a tapered surface 106 is formed.

[00103]In use, to connect the inlet 14 into the plumbing installation using the components 4, the tube adaptor insert 86 is inserted into the inlet 14 until the end 94 of the tube adaptor insert 86 abuts against the second annular ledge 42 inside the housing 12.

[00105] EXAMPLE EMBODIMENT OFA SPECIFIC VALVE: ISOLATION VALVE

[00106] An example embodiment of a specific valve will now be described with particular reference to Figures 12 to 23. The valve illustrated in Figures 12 to 23 is a ball valve, which is often used as an isolation valve. For example, an isolation valve is used with water heater plumbing installations. An isolation valve is typically connected to the water inlet of the water heater and also to the gas inlet of the water heater, in the case that the water heater is fuelled by gas.

[00107]In the embodiment of the valve shown in Figures 12 to 23, the screw thread provided at the inlet of the valve is a male (i.e. external) screw thread (in contrast to Figures 2 to 11, in which a female screw thread 22 is provided at the inlet 14). In addition, in the embodiment of the valve shown in Figures 12 to 23, a loose nut, with an optional reducer adaptor, is provided at the outlet. It is to be understood that a reducer adaptor may be provided with any valve unit in accordance with the present invention.

[00108]In Figures 15 to 23, the outlet side of the valve unit has been omitted. However, it is to be understood that it may be the same as shown and described with reference to the embodiment shown in Figures 12 to 14.

[00109]In such an application, a comprehensive form of the valve installation adaptor kit may include components that enable installation of either, or both, a water valve and a gas valve for connection to one or more tube sizes using a compression connection (for water only) or a flared connection (for water or gas) and connection to water heater inlets of one or more sizes. In Australia, at least, the most common tube sizes are % inch and1/2 inch. The most common water heater inlet sizes are also % inch and1/2 inch. These sizes refer to the external diameters of the tube and water heater inlet. However, the versatility of the present invention means that valve installation adaptor kits may be comprised of the components required for installation in the application, or applications, intended for the particular kit. For example, a valve installation adaptor kit may include only the components to install a water valve and/or gas valve using a compression or flared connection for only % inch size tube and % inch size water heater inlet; as another example, a valve installation adaptor kit may include only the components to install a water valve and/or gas valve using a only flared connection for only1/2 inch size tube and 1/2 inch size water heater inlet; as a further example, a valve installation adaptor kit may include only the components to install a water valve and/or gas valve using a only flared connection for only1/2 inch size tube and % inch size water heater inlet. Thus, a valve installation adaptor kit in accordance with the present invention may include a variety of combinations of components depending upon how varied are the installation options required.

[00110] As previously herein before described, central to any valve installation adaptor kit of the present invention is the valve unit, identified by reference numeral 210 in Figures 12 to 23 of the drawings. The valve unit 210 comprises a housing 212, an inlet 214, an outlet 216 and a rotatable ball 218 operable by a handle 220 to open and close the valve unit 210 to thereby respectively allow or prevent fluid flow therethrough between the inlet 214 and the outlet 216. The inlet 214 and outlet 216 are provided at respective ends of the housing 212. A passage 222 extends through the housing 212 of the valve unit 210 between the inlet 214 and the outlet 216. The rotatable ball 218 has a bore 224 therethrough. Seals 226 and 228 are provided at opposite ends of the rotatable ball 218, one seal 226 on the inlet side of the valve unit 210 and the other seal 228 on the outlet side of the valve unit 210. The handle 220 engages a spindle 230, which engages the rotatable ball 218. Seals 232 are provided between the spindle and an offset portion 234 of the housing. Rotation of the handle 220 causes the rotatable ball 218 to rotate between a first position in which the bore 224 is aligned with the passage 222 (the open condition of the valve unit 210) to allow fluid flow through the valve unit 210, and a second position in which the bore 224 is at substantially a right angle to the passage 222 (the closed condition of the valve unit 210) to prevent fluid flow through the valve unit 210. The seals 226 and 228 prevent fluid flow past the rotatable ball other than through the bore 224 in the open condition of the valve unit 210. The rotatable ball 218, handle 220, bore 224, seals 226 and 228, spindle 230 and seals 232 may be of conventional form. The rotatable ball 218, seals 226 and 228, spindle 230 and seals 232 form the operational components of the valve unit 210 inside the housing 212.

[00111] A screw thread 236 is provided on the valve unit 210 adjacent the inlet 212. The screw thread 236 is a male screw thread 236 (i.e. an external thread). The male screw thread 236 is provided on the exterior of the housing 212.

[00112] The size (i.e. the external diameter) of the male screw thread 236 is greater than the size (i.e. the external diameter) of the largest size tube that will be connected to the valve unit 210.

[00113] A loose nut 238 is provided adjacent the outlet 216. The loose nut 238 may be used to connect the valve unit 210 to the inlet of a water heater. Alternatively, another component (namely, a reducing screw thread adaptor) of the valve installation adaptor kit may be connected to the loose nut 238, as will be further herein described.

[00114]In conventional manner, the loose nut 238 may be provided with a flange 238a and retained by a flange 239 provided adjacent the outlet 216. The flange 238a abuts with the flange 239, which prevents the loose nut 238 sliding off. Also in conventional manner, a seal 240 is provided to abut the face of the flange 239 adjacent the outlet 216, and the loose nut 238 is provided with a female screw thread 241. The female screw thread 241 provides a screw thread at the outlet 216.

[00115]The housing 212 may be made in two parts 242 and 244, which are screw threadedly connected together as shown in the drawings by reference numeral 246. Hexagonal flat surfaces 242a and 242b are provided on the two parts 242 and 244, respectively, such that the two parts 242 and 244 can be gripped by a suitable tool/s to screw threadedly connect them together.

[00116] A first annular ledge 248 is provided inside the housing 212. The first annular ledge 248 is provided between the inlet 214 and the rotatable ball 218. A second annular ledge 250 is provided inside the housing 212. The second annular ledge 250 is provided between the first annular ledge 248 and the rotatable ball 218. The seal 226 abuts a first face 252 of the second annular ledge 250 that faces the rotatable ball 218.

[00117] The first annular ledge 248 is formed as a step in the wall of the housing 212 such that the diameter of the passage 222 in the housing 212 is greater on the inlet side 254 of first annular ledge 248 than on the outlet side 256 of the first annular ledge 248. That is to say, there is a reduction in the diameter of the passage 222 at the first annular ledge 248, in the direction from the inlet 214 to the outlet 216.

[00118] The second annular ledge 250 is formed as a projection from the wall of the housing 212 and has two faces 252 and 258.

[00119] The first annular ledge 248 and the second annular ledge 250 may be formed in the housing 212 at the time of manufacture of the housing 212, such that they are an integral part of the housing 212.

[00120] A nut 260 is engageable with the male screw thread 236 of the valve unit 212 via a female screw thread 262 (i.e. an internal thread), which extends from a first end 264 of the nut 260, part way into the nut 260. The end 264 of the nut 260 is the end that faces the inlet 214 of the valve unit 210 when the nut 260 is presented to the valve unit 210 to engage the male screw thread 236. An annular ledge 266 is provided on the inside of the nut 260. The annular ledge 266 is provided between the first end 264 and the second opposed end 268 of the nut 260.

[00121] The annular ledge 266 is formed as a step in the wall of the nut 260 such that the diameter of the inside diameter of the nut 260 is greater on the first end side 270 of the annular ledge 266 than on the second end side 272 of the annular ledge 266. That is to say, there is an increase in the inside diameter of the nut 260 at the annular ledge 266, in the direction from the second end 268 the first end 64 ofthe nut 260.

[00122] An annular bevel surface 274 is provided in the wall of the nut 260 between the first end 264 and the second end 268. The annular bevel surface 274 extends between the annular ledge 266 and the inside surface 276, of the nut 260, that leads to the second end 268.

[00123]In conventional manner, a passage 278 extends through the nut 260 between the first end 264 (at which there is an opening 280) and the second end 268 (at which there is an opening 282).

[00124] First Tube Size - Compression Connection

[00125]In Figures 12 to 14, there is shown a fifth embodiment of components, generally shown by reference numeral la, of a valve installation adaptor kit of the present invention. The components la are used for an installation using a compression connection to connect a tube to the valve unit 210.

[00126] The components la include a valve unit 210 and nut 260, which have been herein before described, a compression tube adaptor insert 2100 and an olive 2102.

[00127] The compression tube adaptor insert 2100 is substantially in the form of a ring. An 0-ring 2104 is provided in a groove at the outer circumferential surface of the compression tube adaptor insert 2100. An annular bevel 2106 is provided at at least one side face 2108 of the compression tube adaptor insert 2100. In Figures 1 to 3, an annular bevel 2106 is provided at both side faces 2108.

[00128]In use, the compression tube adaptor insert 2100 is insertable into the housing 212 via the inlet 214 such that it abuts against the first annular ledge 248. In the case that an annular bevel 2106 is provided on only one side face 2108 of the compression tube adaptor insert 2100, the annular bevel 2106 should face toward the inlet 214; that is to say, the annular bevel 2106 does not abut against the first annular ledge 248.

[00129] The olive 2102 is of the size required for use with the tube that will be connected to the valve unit 210.

[00130] The components la may further include a reducing thread adaptor 284 engageable with the loose nut 238. The reducing thread adaptor 284 is provided with a male screw thread 286 that extends from adjacent a first end 288. The male screw thread 286 is engageable with the female screw thread 241 of the loose nut 238. The thread reducing adaptor 284 is provided with a female screw thread 290 that extends from adjacent its second end 292. The size of the female screw thread 292 of the reducing thread adaptor 284 is less than the size of the female screw thread 241 of the loose nut 238. The reducing thread adaptor 284 is used when the size of the inlet of the water heater is less than the size of the female screw thread 241 of the loose nut 238.

[00131] A seal 294 is provided to abut an annular surface 296 in the reducing thread adaptor 284.

[00132] Second Tube Size - Compression Connection

[00133]In Figures 15 to 17, there is shown a sixth embodiment of components, generally shown by reference numeral 2a, of a valve installation adaptor kit of the present invention. The components 2a are used for an installation using a compression connection to connect a tube (not shown) to the valve unit 210, when a tube of smaller diameter needs to be connected to the valve unit 210.

[00134] The components 2a include a valve unit 210 and nut 260, which have been herein before described, a (compression) tube adaptor insert 2110 (which functions as a tube stop), a tube support adaptor 2112 and an olive 2114.

[00135] The tube adaptor insert 2110 is substantially in the form of a ring or cylinder. An 0-ring 2116 is provided in a groove at the outer circumferential surface of the tube adaptor insert 2110. An annular bevel surface 2118 is provided at one (first) side face 2120 of the tube adaptor insert 2110. An annular ledge, or annular surface, 2122 is provided at the other (second) side face 2124 of the tube adaptor insert 2110.

[00136] The tube support adaptor 2112 is of substantially ring form. An 0-ring 2126 is provided in a groove at the outer circumferential surface of the tube support adaptor 2112. An annular bevel surface 2128 is provided at the end 2130 of the tube support adaptor 2112 that is inserted into the inlet 214 of the housing 212. The end 2130 is flared outwardly such that a tapered surface 2132 is formed.

[00137] The olive 2114 is of the size required for use with the tube that will be connected to the valve unit 210. The olive 2114 is of a smaller diameter than the olive 2102, since the tube has a smaller diameter.

[00138] In use, to connect the inlet 214 into the plumbing installation using the components 2a, the tube is passed through the nut 60 and then the tube support adaptor 2112, the olive 2114 and then the tube adaptor insert 2110, and the tube is inserted into the inlet 214. The end of the tube abuts against the annular ledge 2122 of the tube adaptor insert 2110. The tube adaptor insert 2110 abuts against the second annular ledge 258 in the housing 212. The female screw thread 262 of the nut 260 is engaged with the male screw thread 236 of the housing 212. Tightening the screw threads 262 and 236 crushes the olive 2102 between the annular bevel surface 2118 of the tube adaptor insert 2110 and the annular bevel surface 2128 of the tube support adaptor 2112. The end 2130 of the tube support adaptor 2112 abuts against the annular ledge 248 inside the housing 212. The tapered surface 2132 of the tube support adaptor 2112 abuts the annular bevel surface 274 of the nut 260. This forms a compression connection.

[00139] First Tube Size - Flared Connection

[00140]In Figures 18 to 20, there is shown a third embodiment of components, generally shown by reference numeral 3a, of a valve installation adaptor kit of the present invention. The components 3a are used for an installation using a flared connection to connect a tube to the valve unit 210.

[00141] The components 3a include a valve unit 210 and nut 260, which have been herein before described, and a (flared) tube adaptor insert 2134 (which functions as a tube stop).

[00142] The tube adaptor insert 2134 has an end 2136 that abuts with the second annular ledge 248 when the tube adaptor insert 2134 is inserted into the housing 212 through the inlet 214.

[00143] The tube adaptor insert 2134 has an 0-ring 2138 provided in a groove provided in an annular extension 2140 at the outer circumferential surface of the tube adaptor insert 2134. The annular extension 2140 is provided at the end 2142 of the tube adaptor insert 2134 that abuts with the second annular ledge 248 when the tube adaptor insert 2134 is inserted into the housing 212 through the inlet 214. The other end 2144 of the tube adaptor insert 2134 is provided with a bevel, or tapered, surface 2146.

[00144]In use, to connect the inlet 214 into the plumbing installation using the components 3a, the tube adaptor insert 2134 is inserted into the inlet 214 until the end 2136 of the tube adaptor insert 2134 abuts against the first annular ledge 248 inside the housing 212. The O-ring 2138 provides a seal inside the housing 212, at this location, between the wall of the housing 212 and the outer surface of the tube adaptor insert 2134. The tube is inserted through the nut 260. A flare is formed at the end of the tube. The flare may be formed in a conventional way. The flared end of the tube is positioned to abut the bevel surface 2146 of the tube adaptor insert 2134, which is now positioned inside the housing 212 as previously herein described. The female screw thread 262 of the nut 260 is engaged with the male screw thread 236 of the housing 212. As the screw threads 262 and 236 are tightened, the flared end of the tube is tightly gripped, in a vice-like manner, between the annular bevel surface 274 of the nut 260 and the bevel surface 2146 of the tube adaptor insert 2134. This forms a flared (tube) connection.

[00145] Second Tube Size - Flared Connection

[00146]In Figures 21 to 23, there is shown a fourth embodiment of components, generally shown by reference numeral 4a, of a valve installation adaptor kit of the present invention. The components 4 are used for an installation using a flared connection to connect a tube (not shown) to the valve unit 210 to thereby connect the inlet 214 of the valve unit 210 into a plumbing installation. The components 4a are used for a plumbing installation using a flared tube connection to connect a tube to the valve unit 210, when a tube of smaller diameter needs to be connected to the valve unit 210.

[00147] The components 4a include a valve unit 210 and nut 260, which have been herein before described, a (flared) tube adaptor insert 2148 (which functions as a tube stop) and tube support adaptor 2150.

[00148] The tube adaptor insert 2148 has an 0-ring 2152 provided in a groove provided in an annular extension 2154 at the outer circumferential surface of the tube adaptor insert 2148. The annular extension 2154 is provided at the end 2156 of the tube adaptor insert 2148 that abuts with the first annular ledge 248 when the tube adaptor insert 2148 is inserted into the housing 212 through the inlet 214. The other end 2158 of the tube adaptor insert 2148 is provided with a bevel, or tapered, surface 2160.

[00149] An 0-ring 2162 is provided in a groove at the outer circumferential surface of the tube support adaptor 2150. An annular bevel surface 2164 is provided at the end 2166 of the tube support adaptor 2150 that is inserted into the inlet 214. The portion near end 2166 is flared outwardly such that a tapered surface 2168 is formed adjacent to a flange 2170. The flange 2170 is provided at the end 2166.

[00150] In use, to connect the inlet 214 into the plumbing installation using the components 4a, the tube adaptor insert 2148 is inserted into the inlet 214 until the end 2156 of the tube adaptor insert 2148 abuts against the first annular ledge 248 inside the housing 212. The 0-ring 2152 provides a seal inside the housing 212 between the wall of the housing 212 and the outer surface of the tube adaptor insert 2152. The tube is inserted through the nut 260 and then the tube support adaptor 2150. A flare is formed at the end of the tube. The flare may be formed in a conventional way. The flared end of the tube is positioned to abut the bevel surface 2160 of the tube adaptor insert 2148, which is now positioned inside the housing 212, as previously herein described. The female screw thread 262 of the nut 260 is engaged with the male screw thread 236 of the housing 212, with the tube support adaptor 2150 between the tube adaptor insert 2148 and the nut 260. As the screw threads 262 and 236 are tightened, the flared end of the tube is tightly gripped, in a vice-like manner, between the bevel surface 2160 of the tube adaptor insert 2148 and the annular bevel surface 2164 that is provided at the end 2166 of the tube support adaptor 2150. This forms a flared (tube) connection.

[00151]Other Types of Connections

[00152] Whilst the embodiments of the present invention herein before described use a compression connection or flared connection to connect the tube, any suitable alternative type of connection may be used. For example, the adaptor means may be structured so that a crimp type or push-fit connection may be used to connect the tube.

[00153] Accordingly, the present invention provides a universal valve installation adaptor kit, which includes a valve unit and components from which a plumber, or other installer, can select, at the point of installation, the required inlet and outlet end connection adaptor options for a wide range of installation options for valve inlet/outlet size and type of plumbing inlet and outlet connection is required.

[00154] One of the major advantages to this approach is that the plumbing merchant only needs to carry one kit on the shelf and the installing plumber one kit in their vehicle. This not only saves cash flow but valuable shelf space and peace of mind.

[00155] The valve installation adaptor kit of the present invention may be supplied complete in one box and includes the valve unit of choice and a range of end connection options which not only allows for differing size plumbing connections but also a range of pipework connection adaptors.

[00156] The male or female end connections on the valve unit of choice is the foundation block for a myriad of end connection sizes and pipework adaptor options necessary to suit a range of plumbing installations.

[00157] Plumbing pipework connections to valves and fittings worldwide are many and varied and the adaptors in the universal kit may be tailored to suit. For example, in Australia the household copper plumbing pipework sizes are a nominal 15mm but actually 12.7mm OD ( 1/2" ) and a nominal 20mm but actually 19.05mm OD ( 3/4" ). In the UK the household copper plumbing pipework sizes are actuallyl5mm OD and 22mm OD.

[00158] Whilst preferred embodiments of the present invention have been herein before described, the scope of the present invention is not limited to those specific embodiments, and may be embodied in other ways, as will be apparent to a skilled addressee.

[00159] Modifications and variations such as would be apparent to a skilled addressee are deemed to be within the scope of the present invention.
