Description

TECHNICAL FIELD The present disclosure relates to devices for fluidly connecting a radiator valve assembly to a radiator body, and methods of manufacturing these devices. The present disclosure further relates to radiators having devices for fluidly connecting a radiator valve assembly to a radiator body, and methods of manufacturing radiators having devices for fluidly connecting a radiator valve assembly to a radiator body. INTRODUCTION The current industry standard when fitting a new water filled radiator is to first connect the component commonly known as a radiator tail, which is usually manufactured from chrome plated brass, to the body of the radiator. The radiator tail has a male Vi BSP(G)(British Standard Pipe) parallel thread on one end which connects into the radiator body by way of a Vi BSP(G) female parallel thread. Each radiator typically comprises a radiator tail that is respectively connected to the flow side of the boiler, and another radiator tail respectively connected to the return side of the boiler. On the other end of the radiator tail is a length of 15mm pipe with a union nut trapped behind an olive which forms a compression joint when tightened so that a radiator valve can be attached to either side of the radiator. The radiator valves are then also attached via a compression joint to the central heating pipes coming from and returning to the boiler. In the middle of the radiator tail is a flat to accommodate a spanner when tightening the radiator tail into the radiator body. However, despite the screwing and tightening of the radiator tail into the radiator body, the screwed connection is prone to leaking. Accordingly, one approach towards achieving a watertight fit when screwing radiator tails into the radiator body is to wrap the male thread with PTFE tape. Often, however, the radiator tail is insufficiently wrapped with PTFE tape, resulting in a leak. If the radiator leaks, the system, or at least the radiator itself, will have to be drained to remove the leaking valve and refitting it after removing the previous strand of PTFE tape and retaping it again with more turns, or, alternatively, attempting to use a sealant. This, however, does not guarantee that refitting the tail with more PTFE tape has cured the leak. This process could be repeated several times before a good dry seal is achieved and can prove costly and frustrating to the fitter, who may be required to spend time revisiting premises to rectify the leak, and it may also prove to be detrimental to their professional reputation should this leakage require further rectification. Furthermore, if a system drain is required to work on a leaking radiator tail then any inhibitor which was added in the filling process is lost and will have to be added again after the leak is rectified and the system refilled. This will significantly add to the cost of what should be a simple and straightforward task of connecting a component to a radiator to facilitate its further connection to a central heating system. It is therefore an object of the present disclosure to mitigate or obviate the disadvantages as set out above.

The sealed bond 112 formed between the first conduit 108 and the second conduit 110 is a welded bond 112. The second conduit 110 is formed from a metal or metal alloy, such as steel for example. The second conduit 110 is a tubular second conduit 110. In the embodiment shown the second conduit 110 has an outer diameter of 15 mm. However, it will be readily understood to the skilled person that the second conduit 110 need not be restricted to an outer diameter of 15 mm, and other diameters may be used as required. The second conduit 110 is a pipe 110 that is readily connectable to a radiator valve assembly 102. The device 100 for fluidly connecting the radiator valve assembly 102 to the radiator body may be manufactured by providing the first conduit 108 for forming a part of the device 100, the first conduit 108 having an internal volume for fluid flow therein and being configured to divert fluid to and / or receive fluid from a radiator body and being fluidly connectable to the radiator body; and sealably bonding a second conduit 110 directly to the first conduit 108 to form the watertight seal 112, said second conduit 110 being fluidly connectable to a radiator valve assembly 102. In use, the watertight seal 112 formed by sealably bonding the second conduit 110 to the first conduit 108 obviates the need for tradespersons or homeowners to use indeterminate quantities of PTFE tape to form a watertight seal using a radiator tail valve, thereby providing, for example, these persons with assurance that no leakage of water will occur, as well as reducing manual labour involved with installation and maintenance of such radiators. Manufacturing the device 100 as shown in Figures 1 to 4 comprises inserting a portion of the second conduit 110 into the internal volume of the first conduit 108. The portion is inserted into the internal volume of the first conduit 108 through the second through bore 116b. The second conduit 110 is then sealably bonded, and more preferably, weldably bonded to a surface of the first conduit 108. In the non-limiting example shown, sealably bonding the second conduit 110 directly to the first conduit 108 comprises thermally bonding the second conduit 110 directly to the first conduit 108, for example, welding the second conduit 110 directly to a surface of the first conduit 108.

The protective coat may comprise chromium. The protective coat may be configured to protect against corrosion in use, such as galvanic corrosion In Figure 3, there is shown the device 100 as shown in Figures 1 and 2. Furthermore is shown a radiator valve assembly 102. The device 100 has yet to be fluidly connected to the radiator valve assembly 102.

The radiator can be manufactured by prefabricating at least one device 100 (one shown), as shown in Figures 1 and 2, for fluidly connecting a radiator valve assembly 102 to a radiator body; and sealably bonding the at least one prefabricated device 100 to the radiator body to fluidly connect the prefabricated device 100 to the radiator body. The at least one device 100 is thermally bonded by welding the at least one device 100 to the radiator body to fluidly connect the device 100 to the radiator body. The radiator may then be fitted and the second conduit 110 may then be fluidly connected to the radiator valve assembly 102. Now referring to Figures 5 to 8, there is shown another example device 200 for fluidly connecting a radiator valve assembly 202 to the radiator body (not shown). The device 200 shown is similar to the device shown in Figures 1 to 3, and like numerals are used to indicate like components.

The watertight seal 212 is configured to maintain its structural integrity in use. The watertight seal 212 is a heat-durable seal. The watertight seal 212 is a pressure-resistant seal 212. The watertight seal 212 is configured to maintain its structural integrity in response to repeated and / or continuous exposure to pressurised fluids in use. The watertight seal 212 is configured to maintain its structural integrity in response to repeated and / or continuous exposure to high temperature conditions in use.

The second conduit 210 is sealably bonded, and in particular, weldably bonded to the washer 220 to form the watertight seal 212. In use, the welding of the second conduit 210 to the washer 220 bonded to the first conduit 208 forms the watertight seal 212, thereby obviating the risk of water leaking between the first conduit 208 and the second conduit 212. The washer 220 functions as a welding point for sealably bonding the second conduit 210 thereto, and in particular, weldably bonding the second conduit 210 thereto to form the watertight seal 212. The washer 220 is adapted to receive the second conduit 210 therethrough. The washer 220 has an aperture 224 adapted to receive the second conduit 210 therethrough. The aperture 224 is defined by a smooth inner surface 226 of the washer. The diameter of the aperture 224 corresponds to the outer diameter of the second conduit 210. In use, the intermediary bonding means 220 being a washer 220 is advantageous, as the smooth inner surface 226 of the washer 220 aids in formation of the watertight seal 212. Furthermore, the diameter of the aperture 224 corresponding to the outer diameter of the second conduit 210 means that the aperture 224 may receive the pipe 210 therethrough such that the pipe 210 is in contact with or in close proximity with the inner surface 226 of the aperture 224, which enables a strong, watertight seal to be easily formed. In embodiments where the intermediary bonding means 220 comprises more than one washer 220, each washer 220 may be weldably bonded to an adjacent washer 220. The second conduit 210 is sealably bonded indirectly to the first conduit 208 by being weldably bonded indirectly to the first conduit 208 to form the watertight seal 212. The watertight seal 212 comprises a sealed bond 212, and in particular, a welded bond 212 between the second conduit 210 and the washer 220, the washer 220 being pre-bonded to the first conduit 208. In other examples not shown, the second conduit may be sealably bonded directly and indirectly to the first conduit, wherein the watertight seal comprises a first sealed bond, and in particular, a first welded bond between the first conduit and the second conduit, and a second sealed bond, and in particular, a second welded bond between the second conduit and an intermediary bonding means, such as a washer for example, that is bonded to the first conduit. In use, the second conduit 210 being sealably bonded directly and / or indirectly, and in particular, weldably bonded directly and / or indirectly to the first conduit 208 to form the watertight seal 212 obviates the risk of leakage of fluid from the joint. The device 200 shown in Figures 5 to 8 is manufactured by providing the first conduit 208 for forming a part of the device 200, the first conduit 208 having an internal volume for fluid flow therein and being configured to divert fluid to and / or receive fluid from a radiator body and being fluidly connectable to the radiator body; and sealably bonding a second conduit 210 indirectly to the first conduit 208 to form a watertight seal 212, said second conduit 210 being fluidly connectable to a radiator valve assembly 202. Sealably bonding the second conduit 210 indirectly to the first conduit 208 comprises thermally bonding the second conduit 210 indirectly to the first conduit 208, for example, welding the second conduit 210 indirectly to the first conduit 208. In use, the welding of the second conduit 210 indirectly to the first conduit 208 ensures that no leakage of water will occur, as it is sealably bonded to the intermediary bonding means 220 which is bonded to the first conduit 208. Welding the second conduit 210 indirectly to the first conduit 208 comprises sealably bonding an intermediary bonding means 220, such as a washer 220 in the example device shown in Figures 5 to 8, to the first conduit 208. Sealably bonding the washer 220 to the first conduit 208 comprises welding the washer 220 to the first conduit 208, and in particular, to an outer surface of the second hollow body portion 214b of the first conduit 208.
