Abstract

The flange consists of a tube 2 that includes a flared end 24 inserted into a disc or ring 4. A vent port 16 is situated under the disc/ring. The flange is inserted into a universal compression coupling 6. A branch tree 12 connects outlet pipe 10 at 8 and hot water cylinder 14. Two separate outlet channels 22 and 24 may provide an independent flow to a shower outlet 18. A main vent outlet for heated fluid expansion and secondary hot tap demand is via tube 2, 24, and 26.

Description

SHOWER DISC FLANGE

TECHNICAL FIELD

The invention relates to improving the quality and quantity of hot water that is available for shower use on demand.

BACK GROUND OF INVENTION

When water is heated up in the hot water cylinder. The gas formation that occurs during the process, affects the quality of hot water that is drawn from the top of the cylinder/vent supply', for shower requirement. The amount of hot water flovving to the shower can also be affected if a secondary out let for hot taps is connected to the same vent supply.

The fully open vent system that is generally in use on a hot water cylinder can also result in valuable fluid heat loss through the vent when the water is being heated or stored. Heated hot water that is not used is a waste of energy and resources.

OBJECTS AND SUMMERY OF INVENTION

As the water in the cylinder is heated up, the hot fluid rises to the top of the cylinder and replaces the cooler water at the top.

The hot water, also heats up the fluid in the vent pipe that is connected to the top of the cylinder and escapes into the expansion tank as wasted hot water.

The invention reduces heat loss through the vent and ensures priority hot water to the shower even when a second demand out let to the hot taps is in demand while the shower is in use. The invention comprises of a disc witch a hole in the centre. A tube with an outer diameter that is similar to the diameter of hole in the disc is inserted into the disc and secured on one end of the tube.

The invention is installed and secured in a coupling. The coupling is inserted into a cut section of the vent supply out let from the top of the cylinder, with the longer end of the tube inserted into the cylinder though a branching tee that is connected to the top of the cylinder. The branching tee is between the coupling and the cylinder.

The primary supply is from the cylinder into the branching tee. The second out let in the middle of the branching tee is for shower out let. The out let from the tee on the opposite side of the cylinder, is connected to the vent and secondary pipe out let.

The tube that extends from the coupling through the tee and terminates in the cylinder creates two channels in the water coming out of the top of the cylinder. The main vents tap demand out let is through the centre of the tube that terminates within the cylinder. A second channel that provides the flow to the showers is through the outer channel in the branching tee and flows out of the middle of the tee from the top of the cylinder. The branching tee linl<:s the coupling with the invention on to the cylinder.

The length of the tube (as in Fig 1) can be lengthen into the cylinder. This will result in more hot water for the shower in preference to any secondary out let that may be required for hot taps The invention also reduces the possibilities of air being drawn through the open vent when the pump Is operational. As the main vent supply out let is through the channel m middle of the tube that terminates in the cylinder. Where as the shower supply is through a separate channel in the tee that is form on the external part of the invention with In the branching tee, as the tube is inserted into the tee. Trapped air and gas build up with in the secondary channel is released through a permanent micro open vent at the top of the tube beneath the disc into the main vent in the middle of the tube. As the hot water cannot rise through the open vent directly due to the disc restriction- with in the coupling the water heats "p more rapidly beneath the disc in the second channel.

Water heat exchange at this point is mainly through the micro port at the top the tube.

I () The Invention can be installed into cylinders with male or female out lets as a unit without the need to acquire specialised fitting to suit the cylinder.

NIORE DETAILED DESCRIPTION

References are made to Fig l 2Q The Disc Flange consists of a tube 2 incorporating a disc 4.

The Flange is inserted into a universal compression coupling 6.

The combined fitting 2,4,6 is then inserted into a cut section of the hot water supply vent out let pipe 10 conning out of the top of the cylinder.

The out let pipe lo is connected to the branching tee 12 at 8.

As the tube 2 is inserted into pipe 10 it passes through branching teel2 into cylinder l 4. This results in the formation of two separate outlet channel, 22 on the external part of the invention and 24 on the internal part of the invention from the cylinder 14 to provide an independent flow to the shower out let l 8.

The main vent out let to allow for heated fluid expansion and secondary hot taps SO demands if required from the cylinder, is through the centre of the tube 2 through 24 and out through vent 26. The length of tube 2 that is submersed into the cylinder can be increase or reduce, to alter the amount of hot water that is available for the shower out At (i.e. a shorter tube 2 will result in less hot water being available for the shower demand, as the exit for the secondary supply /vent out let 24 is near to the shower supply out let 22.

The invention also reducers the need to replace the branch tee 12 that is generally apart of the hot system as the invention can be installed into an existing tee 12 that is already apart of the hot water supply system out of hot water cylinder 14.

By installing the invention to into fittings that is already a part of the installation, additional material and installation cost is reduced that would other wise be required if other products were used.

A permanent open micro vent 16 is situated at the top of the tube underneath the disc.

This part of the invention enables trapped air and gases (from the hot water) that builds underneath the seal disc 4 at the top of channel 22 to escape into the centre of tube 2 into 24 and out into the main vent 26.

Claims

CLAIMS: Rct'erence: Fig I 1) That a tube of an appropriate length. Is

flared at one end.

a) 'chat as in 1 the tube is inserted into a disc or ring and secured so as to be as one unit with the disc/ring.

3) 'I'hat as in 1, 2, the tube is inserted into connector.

4) That as in 1,2,J, the connector is linked to an equal tee fitting through a tube..

5) That as in 1,273 and 4 the equal tee fitting is secured to a cylinder through a Of length of tube to a second comector.

6) 'I'hat as in 1,2,374,5 the connector is secured to the cylinder.
