Mini Expansion Vessels
This application relates to mini expansion vessels, and in particular, to the mini expansion vessels suitable for use in connection with closed hot and cold water circuits in domestic hot and cold water systems.
It is known that in closed water circuits in domestic water systems (hereafter simply referred to as “circuits”), the water cannot be compressed. As a result, a mini expansion vessel (sometimes known as a shock arrestor) is provided to accommodate any increase or decrease in volume of the water within the circuit resultant from an increase or decrease in temperature of the water. This is especially important for hot water circuits. A mini expansion vessel typically has a volume of up to 2 litres.
Known mini expansion vessels comprise a tank in to which a connection means in the form of a conduit or pipe mouths and a diaphragm. The diaphragm divides the tank into first and second volumes, with the first volume being closed, and the second volume has the connection conduit mouthing into it, typically at a location in the expansion vessel remote from the diaphragm. Typically, the diaphragm is comprised of an elastically deformable material.
The first volume contains a gas which is a compressible fluid. The gas may be at a pressure that is not at atmospheric pressure. Typically, the gas is at above atmospheric pressure with the result that unless the second volume is at a greater pressure, the gas pushes and elastically deforms the diaphragm into the second volume. The first volume may be provided with a means for adjusting the pressure in the first volume such as a valve.
The second volume is in direct liquid communication with the water within a circuit via the connection conduit when the connection conduit is connected to an element of the circuit.
When the second volume of the expansion vessel is in direct liquid communication with the water within the circuit via the connection conduit, any change in volume of the water, which will occur when the temperature of the water in the circuit increases or decreases, causes water to be pushed into the expansion vessel or pushed out of the expansion vessel. In particular, when the temperature of the water increases and the water expands in volume then the water is pushed into the expansion vessel pushing the diaphragm towards the first volume and increasing the pressure of the gas therein. When the temperature of the water decreases, the volume of the water decreases and the pressure in the gas in the first volume of the expansion vessel pushes water out of the second volume and into the circuit.
Known expansion vessels are connected via the connection conduit to the circuit with which they are associated. The connection conduit typically has either a smooth or a threaded outer surface adjacent the end of the conduit remote from the expansion vessel. When the connection conduit has a smooth outer surface it is known to join the conduit to an element of the circuit by soldering. When the connection conduit has a threaded outer surface it is known to join the conduit to an element of the circuit via a female threaded socket.
According to the present invention there is provided a mini expansion vessel and circuit connection means characterised in that the circuit connection means is comprised of a connection conduit, and a part of a means for quickly forming a pressure resistant seal with an element of a circuit.
In a first aspect of the present invention the means for quickly forming a pressure resistant seal with an element of a circuit is a compression fitting comprised of male and female portions an inner compression ring sometimes known as an olive or ferrule and an outer compression nut, in which the male portion is comprised of a male conduit with a smooth outer surface, and a female portion is comprised of a female conduit with an at least partially threaded outer surface and at least a portion of the inner surface of the female conduit is so dimensioned that a portion of the male conduit can snugly be inserted into the female conduit when the male and female portions are brought together.
In some preferred embodiments of the present invention the end of the female conduit that is adapted to face the male portion has a bevelled end with the bevel being on the inside face of the threaded outer surfaced conduit.
In some preferred embodiments of the present invention the compression ring is friction fitted to the outer surface of the male conduit.
In some preferred embodiments of the present invention the part of the means for quickly forming a pressure resistant seal with an element of a circuit of the circuit connection means is the female portion, the compression nut is loosely screwed onto the thread of the female conduit and the compression ring is loosely retained between the female conduit and the compression nut.
This embodiment has the advantage that the supply of the mini expansion vessel of the present invention provides the person fitting the expansion vessel with all that they need to connect the mini expansion vessel to a spur on the circuit in a single unit.
In some preferred embodiments of the present invention the part of the means for quickly forming a pressure resistant seal with an element of a circuit of the circuit connection means is the female portion and the compression ring is fixed to the female conduit so that the male conduit can, in one movement, be passed through the compression ring and into the female conduit. In some preferred embodiments the compression nut is loosely screwed onto the thread of the female conduit prior to the insertion of the male conduit.
Again this embodiment has the advantage that the supply of the mini expansion vessel of the present invention provides the person fitting the expansion vessel with all that they need to connect the mini expansion vessel to a spur on the circuit in a single unit. The attachment of the compression ring to the female conduit is, however, particularly beneficial because it has the result that he compression ring will not become separated from the mini expansion vessel.
The means for attaching the compression ring to the female conduit is preferably an adhesive or other substance that serves to retain the compression ring in position. Preferably the adhesive or other substance may have one or more of the following characteristics
- It may act as a watertight seal between the compression ring and the female conduit;
- It may cease to hold the compression ring in position when the compression nut is tightened onto the female conduit;
- It may be a grease or similar and both hold the compression ring in position and lubricate the insertion of the male coupling; and I or
- It may flow when under stress and I or strain.
In some preferred embodiments of the present invention the part of the means for quickly forming a pressure resistant seal with an element of a circuit of the circuit connection means is the female portion, the compression ring is fixed to the compression nut and the compression nut is loosely screwed onto the thread of the female conduit so that the male conduit can, in one movement be passed through the compression nut, the compression ring and into the female conduit. The compression ring may be attached to the compression nut by a suitable adhesive or similar substance. The adhesive or similar substance may have one or more of the characteristics described above in connection with some alternative embodiments of the present invention.
In some preferred embodiments of the present invention the circuit connection means further comprises a means suitable for engagement with a tool so as to prevent rotation of circuit connection means. Most preferably the means for preventing rotation is in the form of at least one pair of parallel flat faces suitable for engagement with a spanner, wrench or similar tool. Alternative configurations such as splines, gear teeth or the like may be incorporated and full within the scope of the present invention.
The compression ring of the present invention may be comprised of a suitable material such as copper, inox steel, a plastics or any other appropriate material.
The compression nut maybe of any suitable material such as brass or inox steel.
According to a second aspect of the present invention there is provided a kit for the fitting of a mini expansion vessel comprising a mini expansion vessel according to the first aspect of the present invention and technical data on the mini expansion vessel.
According to a third aspect of the present invention there is provided a method of construction of a circuit comprising the fitting of a mini expansion vessel according to the first aspect of the present invention to the circuit via a spur from that circuit.
The present invention will be further described and explained with reference to the accompanying figures in which
Figure 1 shows an embodiment of a mini expansion vessel according to the first aspect of the present invention; and
Figure 2 shows a sectional view of the embodiment of Figure 1
With reference to Figures 1 and 2, a mini expansion vessel (2) is comprised of a tank (4) and a connection conduit (6). The tank (4) is comprised of a first volume (8) which is filled with gas, a second volume (10) into which mouths the connection conduit (6), and a diaphragm (12) which separates the first and second volumes (8) and (10).
The tank (4) is provided with a valve (14) which can be used to adjust the pressure of the gas in the first volume (8).
The connection conduit (6) is partially threaded (16) on the outside face of the conduit adjacent the end of the conduit remote from the tank (4). The thread (16) is suitably dimensioned so as to allow it to engage with a thread (not shown) on a compression nut (18). The inside bore (20) of the connection conduit (6) adjacent the end of the conduit remote from the tank (4) is of a suitable dimension to allow the sliding insertion of a male conduit (not shown). The male conduit may be a spur from a domestic water circuit. The inside edge of the connection conduit (6) adjacent the end of the conduit remote from the tank (4) has a bevel (24).
A compression ring (22) is located adjacent the end of the conduit remote from the tank (4), and is held in position by the compression nut (18). Insertion of the male conduit (not shown) through the compression nut (18), compression ring (22), and into the bore (20) and subsequent tightening of the compression nut (18) forms a water tight joint between the male conduit (not shown) and the connection conduit (6).
In some embodiments of the present invention the compression ring 5 (22) is attached to the connection conduit (6) at the bevel (24) by a suitable adhesive or similar substance (not shown). The adhesive or similar substance may form a seal between the compression ring (22) and the bevel (24). Alternatively or additionally the adhesive or similar substance (not shown) may be designed to release the compression ring (22) or flow when subject to a predetermined level of stress or strain such as would be experienced when the compression nut (18) is tightened.
In other embodiments of the present invention the compression ring (22) is attached to the compression nut (18) by a suitable adhesive or similar substance (not shown). The adhesive or similar substance may form a seal between the compression ring (22) and the compression nut (18). Alternatively or additionally the adhesive or similar substance (not shown) may be designed to release the compression ring (22) or flow when subject to a predetermined level of stress or strain such as would be experienced when the compression nut (18) is tightened.
The connection conduit (6) further comprises a nut configuration (26) adapted to be engaged with by a spanner (not shown). The nut configuration (26) and the spanner (not shown) can be used to prevent rotation of the connection conduit (6) about its longitudinal axis when the compression nut (18) is tightened.
