Description
241 1 732 A fluid distribution manifold The invention relates to a fluid
distribution manifold.
The invention provides a fluid distribution manifold including: a flow trunk conduit, a flow branch conduit connected to the flow trunk conduit, so oriented in relation to the flow trunk conduit as to convey fluid from the flow trunk conduit in directions across the fluid flow direction in the flow trunk conduit, a return trunk conduit substantially parallel to the flow trunk conduit, a return branch conduit connected to the return trunk conduit, so oriented in relation to the return trunk conduit as to convey fluid to the return trunk conduit from directions across the fluid flow direction in the return trunk conduit, an isolation valve, housed in the flow trunk conduit, positioned to control the entry of fluid into the flow trunk conduit, a flow regulating valve, housed in the return trunk conduit, positioned to control the flow of fluid out of the return trunk conduit, a flow metering device, housed in the return trunk conduit, positioned to measure the flow rate of fluid out of the return trunk conduit and a flow-calming element, housed in the return trunk conduit upstream of the flow metering device, for providing linear flow of fluid towards the flow-metering device.
In one arrangement, the flow-metering device includes an aperture, through which the fluid passes, and the flow-calming element, in operation, effects linear flow of fluid, towards the flow metering device, over a distance of several times the flow aperture of the flow metering device.
2. In an arrangement in which the flow-metering device includes an aperture, through which the fluid passes, effecting a pressure change in the fluid, the flow-calming element, in operation, effects linear flow of fluid, towards the flow metering device, over a distance of several times the flow aperture of the flow metering device In an arrangement in which the flow-metering device includes an aperture, preferably, the flowcalming element includes a straight piece of conduit of length of the order of five times the aperture of the flow-metering device.
Preferably, the branch conduits extend orthogonally from the trunk conduits.
Advantageously, the fluid distribution manifold is combined with a plurality of isolation valves, an air vent and flushing by-pass and drain valves.
Advantageously, the fluid distribution manifold is combined with a similar fluid distribution manifold or a plurality of similar fluid distribution manifolds, the flow trunk conduits of the manifolds being in alignment with and connected to one other, and the return trunk conduits of the manifolds being in alignment with and connected to one another, the isolation valve, the flow regulating valve, the flow metering device and the flow-calming element being omitted from the manifold which is downstream relative to the fluid flow and upstream relative to the return flow.
A fluid distribution manifold and a fluid distribution manifold combined with a similar fluid distribution manifold, in accordance with the invention, will now be described, by way of example only, with reference to the accompanying drawings, in which: Fig. 1 shows the fluid distribution manifold combined with a plurality of valves and Fig. 2 shows the fluid distribution manifold combined with a similar fluid distribution manifold and a plurality of valves.
Referring to Fig. 1 of the accompanying drawings, the fluid distribution manifold includes a flow trunk conduit 1, a return trunk conduit 2, a flow branch conduit 3 and a return branch conduit 4. The flow trunk conduit I and the return trunk conduit 2 lie side by side and are parallel to each other.
The flow branch conduit 3 is orthogonal to the flow trunk conduit I and the return branch conduit 4 is orthogonal to the return trunk conduit 2, so the flow and return branch conduits 3 and 4 lie parallel to each other. A lower part of the flow trunk conduit 1 lies below the flow branch conduit 3 and an upper part of the flow trunk conduit 1 lies above the flow branch conduit 3, as viewed in the drawing. Further, a left section of the flow branch conduit 3 lies to the left of the flow trunk conduit I and a right section of the flow branch conduit I lies to the right of the flow trunk conduit I, as viewed in the drawing.
In respect of the return trunk conduit 2, a lower part of the return trunk conduit 2 lies below the return branch conduit 4 and an upper part of the return trunk conduit 2 lies above the return branch conduit 4, as viewed in the drawing. Also, a left section of the return branch conduit 4 lies to the left of the return trunk conduit 2 and a right section of the return branch conduit 4 lies to the right of the return trunk conduit 2, as viewed in the drawing.
The lower part of the flow trunk conduit I serves as the input port to the flow trunk conduit I, fluid flowing into and along the lower part of the flow trunk conduit 1 being free to enter the left section of the flow branch conduit 3 to the left, to enter the right section of the flow branch conduit 3 to the right and, also, to continue upwards into the upper part of the flow trunk conduit 1, as viewed in the drawing. The flow directions in the flow branch conduit 3 are orthogonal to the flow direction in the flow trunk conduit I, to the left along the left section of the flow branch conduit 3 and to the right along the right section of the flow branch conduit 3, as viewed in the drawing. An isolation valve 5 at the input port of the flow trunk conduit 1 serves to control the flow of fluid into the flow trunk conduit I. In respect of the return trunk conduit 2, return fluid flowing into the left section of the return branch conduit 4 from the left and flowing into the right section of the return branch conduit 4 from the right, is free to enter the upper part of the return trunk conduit 2 and to continue downwards into the lower part of the return trunk conduit 2, as viewed in the drawing. The flow directions in the return branch conduit 4 are orthogonal the flow direction in the return trunk conduit 2, from the left along the left section of the return branch conduit 4 and from the right along the right section of the return branch conduit 4, as viewed in the drawing.
A flow-regulating valve 6, a flow-metering device 7 and a flow-calming element 8 are housed in the lower part of the return trunk conduit 2. The flow- calming element 8 lies upstream of the flow metering device 7 which is, itself, upstream of the flow regulating valve 6.
The flow-calming element 8 serves to deliver a linear flow of fluid towards the flow-metering device 7, in order that the flow-metering device 7 may deliver an output reading that is free from such error as would result from disturbed flow at the flow metering device or in which such error is minimal.
A suitable form of flow-claming element 8 is a length of straight conduit and a suitable flow-metering device 7 is a length of conduit including an orifice that includes a narrower region, creating a pressure difference between positions on either side of the narrowest part of the orifice. In an arrangement in which flow-metering is effected by a narrowing in a length of the conduit, a straight piece of conduit of length of the order of five times the width of the narrowest part of the orifice is suitable as the flow-calming element 8.
The straight piece of conduit, acting as the flow-calming element 8, serves to provide a straight flow path towards the flow-metering device 7 for long enough for the flow-metering device 7 to function correctly. The flow rate is adjustable by the flow regulating valve 6 as required.
In addition to the isolation valve 5 included in the flow trunk conduit I, there are isolation valves 9, 10, 11 and 12 included at the ends of the flow and return branch conduits 3 and 4, serving to provide controllable connections to devices to the left and right, as viewed in the drawing, which receive heating or cooling fluid from the fluid distribution manifold.
Isolation valves 13 and 14 are connected to the upper parts of the flow and return trunk conduits I and 2, respectively, and flushing drain and flushing by-pass valves 15 and 16 are connected to the isolation valves 13 and 14. Further, the flushing by-pass valve 16 controls access to a manual air vent 17, which is connected to the flushing by pass valve 16.
The use of the fluid distribution manifold is as follows, when the isolation valves 9 to 12 are included and are open and the isolation valves 13 and 14 are included and are shut: Fluid to be distributed to heating or cooling devices, for example, fan coils, is permitted to enter the flow trunk conduit I by the opening of the isolation valve 5 and moves upwards, as viewed in the drawing, through the conduit 1. The fluid in the flow trunk conduit I is free to flow to the left along the flow branch conduit 3 and to the right along the flow branch conduit 3, as viewed in the drawing, when the isolation valves 9 and 12 are open. Fan coils (not shown) to be supplied with heating or cooling fluid are connected to the flow branch conduit 3, by way of the isolation valves 9 and 12, respectively.
Return fluid flow from the fan coils, from right and left, as viewed in the drawing, arrives at the isolation valves 10 and 11 and, when the valves are open, there is flow from the return branch conduit 4 into the return trunk conduit 2, with changes in direction from horizontal to vertical, as viewed in the drawing. The return fluid leaves the fluid distribution manifold by way of the return trunk conduit 2, passing through the flow- calming element 8, the floe-metering device 7 and the flow-regulating valve 6, the flow- regulating valve 6 being operable to control the fluid flow rate through the fan coils to the left and right, as viewed in the drawing.
The inclusion of additional valves 13, 14, 15 and 16 and, also, the manual air vent 17 to the fluid distribution manifold, as shown the drawing, permits the additional use of the fluid distribution manifold for manifold flushing, fan coil forwards and backwards flushing and system fill, during network commissioning, of components of the network.
Following the flushing and the venting of the network, the isolation valves 13 and 14 are closed and the flow control valve 6 is set as required for a particular flow rate as indicated by the flow-metering device 7.
Referring to Fig. 2 of the accompanying drawings, two fluid distribution manifolds may be combined as shown, a second fluid distribution manifold being placed below the first fluid distribution manifold, as viewed in the drawing.
The second fluid distribution manifold includes components corresponding to those of the first fluid distribution manifold shown in Fig. 1. The isolation valve 5, the flow regulating valve 6, the flow metering device 7 and the flow-calming element 8 are no longer required in the first or upper fluid distribution manifold, since the functions are performed by the corresponding components 25, 26, 27 and 28 in the second or lower manifold. The two manifolds are so joined together that the flow trunk conduit 1 of the first manifold is connected to the corresponding flow trunk conduit 2 l of the second fluid distribution manifold. Also, the return trunk conduit 2 of the first manifold is connected to the corresponding return trunk conduit 22 of the second fluid distribution manifold.
The two manifolds together have the capacity to supply working fluid to twice as many services as a single manifold. In this case, each manifold has the capacity to supply working fluid to two services and the two manifolds have the capacity to supply working fluid to four services, by way of the valves 9 to 12 and 10 and 29, 210, 21 1 and 212, when connected together.
Flushing and venting during commissioning of a network that includes a plurality of fluid distribution manifolds is carried out as described above in relation to Fig. 1.
Further fluid distribution manifolds may be attached below the second fluid distribution manifold, as viewed in the drawing, forming a stack, in order to feed further heating or cooling devices.
A stack of the fluid distribution manifolds is especially suitable for supplying heating or cooling fluid to devices at the plurality of levels of a multi-level building, outputs to and inputs from the left and right being supplied from a vertical stack of the fluid distribution elements.
As shown in Figs. I and 2, the branch conduits guiding flow to the left and right and accepting flow from left and right are orthogonal to the trunk conduits guiding flow up and down. However, it will be appreciated that the branch conduits guiding flow to the left and right and accepting flow from left and right need not be orthogonal to the trunk conduits guiding flow up and down, so long as the two sets of flow are more or less across each other and permit the supply of heating or cooling fluid to devices at the plurality of levels of a multi-level building, from a vertical stack of the fluid distribution elements.
Also, the trunk and branch conduits may have any one of several possible transverse cross-sections, but a circular transverse cross-section is likely to be the most convenient.
