Abstract

A connection assembly is disclosed for connecting a magnetic separator into a central heating system circuit, the magnetic separator including a housing, a separation chamber within the housing, and externally threaded inlet and outlet ports extending from the housing. The connection assembly comprises: a fitment adapted to be received within at least one of the ports of the separator, the fitment including a bore for carrying fluid from/to the central heating circuit to/from the separator; a threaded connector disposed around the bore for securing the fitment to the or each port, the threaded connector having a hand grip area for facilitating tightening of the connector by hand; and a removable force transfer element receivable between the fitment and the threaded connector for transferring force between the threaded connector and the fitment.

Claims

1. A connection assembly for connecting a magnetic separator into a central heating system circuit, the magnetic separator including a housing, a separation chamber within the housing, and externally threaded inlet and outlet ports extending from the housing,

the connection assembly comprising:

a fitment adapted to be received within at least one of the ports of the separator, the fitment including a bore for carrying fluid from/to the central heating circuit to/from the separator;

a threaded connector disposed around the bore for securing the fitment to the or each port, the threaded connector having a hand grip area for facilitating tightening of the connector by hand; and

a removable force transfer element in the form of a resilient clip receivable between the fitment and the threaded connector for transferring force between the threaded connector and the fitment, and, when installed on the fitment, the removable force transfer element being removable therefrom whilst the fitment and threaded connector remain fitted to the or each port.

2. The connection assembly of claim 1, wherein the resilient clip is part-circular.

3. The connection assembly of claim 1, wherein the force transfer element engages with one end of the threaded connector and holds the threaded connector at a fixed distance from the fitment for causing the port to move away from the fitment as the threaded connector is unscrewed from the port.

4. The connection assembly of claim 1, wherein the threaded connector is formed as an internally threaded collar with a flange at one end thereof, the flange extending inwards from the periphery of the collar.

5. The connection assembly claim 1, wherein the fitment includes first and second spaced peripheral shoulders, in use, the threaded connector bearing against the first peripheral shoulder to hold the fitment to the port of the separator, and the force transfer element bearing against the second peripheral shoulder.

6. The connection assembly of claim 5, wherein the fitment comprises a first part which connects to at least one of the ports and a second part for connection to a valve assembly or further connector.

7. The connection assembly of claim 6, wherein the second part includes a spigot for connection with the first part and a flange extending outwardly from the spigot forming the second peripheral shoulder.

8. The connection assembly of claim 7, wherein a further spigot extends away from the other side of the flange of the second part for connection to the valve assembly or further connector.

9. The connection assembly of claim 6, wherein the first part includes a spigot of a first diameter, which locates within said at least one of the ports, a peripheral flange extending outwardly from the spigot, which in use butts up against the end of said at least one of the ports, the peripheral flange forming the first peripheral shoulder.

10. The connection assembly of claim 9, wherein a further spigot extends away from the peripheral flange in the other direction, the further spigot having a smaller diameter than the first diameter.

11. The connection assembly of claim 1, wherein the bore of the fitment is tapered.

12. A separator and connection assembly, comprising:

a magnetic separator for a central heating system, the magnetic separator including a housing, a separation chamber within the housing, and externally threaded inlet and outlet ports extending from the housing, and a connection assembly, the connection assembly comprising;

a fitment adapted to be received within at least one of the ports of the separator, the fitment including a bore for carrying fluid from/to the central heating circuit to/from the separator;

a threaded connector disposed around the bore for securing the fitment to the or each port, the threaded connector having a hand grip area for facilitating tightening of the connector by hand; and

a removable force transfer element receivable between the fitment and the threaded connector for transferring force between the threaded connector and the fitment, and, when installed on the fitment, the removable force transfer element being removable therefrom whilst the fitment and threaded connector remain fitted to the or each port.

13. The separator and connection assembly of claim 12, wherein the part of the fitment which is received within the port or ports has two spaced circumferential recesses for receiving O-ring seals, and the distal end of each port is internally chamfered for providing a lead-in for the O-ring seals.

14. The separator and connection assembly of claim 13, wherein the chamfered end of each port provides a sealing surface for one of the O-ring seals.

15. The separator and connection assembly of claim 12, wherein the removable force transfer element is a resilient clip.

16. The separator and connection assembly of claim 12, wherein the force transfer element engages with one end of the threaded connector and holds the threaded connector at a fixed distance from the fitment for causing the port to move away from the fitment as the threaded connector is unscrewed from the port.

17. The separator and connection assembly of claim 12, wherein the threaded connector is formed as an internally threaded collar with a flange at one end thereof, the flange extending inwards from the periphery of the collar.

18. The separator and connection assembly of claim 12, wherein the fitment includes first and second spaced peripheral shoulders, in use, the threaded connector bearing against the first peripheral shoulder to hold the fitment to the port of the separator, and the force transfer element bearing against the second peripheral shoulder.

19. A connection assembly for connecting a magnetic separator into a central heating system circuit, the magnetic separator including a housing, a separation chamber within the housing, and externally threaded inlet and outlet ports extending from the housing, the connection assembly comprising:

a fitment adapted to be received within at least one of the ports of the separator, the fitment including a bore for carrying fluid from/to the central heating circuit to/from the separator;

a threaded connector disposed around the bore for securing the fitment to the or each port, the threaded connector having a hand grip area for facilitating tightening of the connector by hand; and

a removable force transfer element receivable between the fitment and the threaded connector for transferring force between the threaded connector and the fitment, and, when installed on the fitment, the removable force transfer element being removable therefrom whilst the fitment and threaded connector remain fitted to the or each port,

wherein the part of the fitment which is received within the port or ports has two spaced circumferential recesses for receiving O-ring seals.

20. A connection assembly for connecting a magnetic separator into a central heating system circuit, the magnetic separator including a housing, a separation chamber within the housing, and externally threaded inlet and outlet ports extending from the housing, the connection assembly comprising:

a fitment adapted to be received within at least one of the ports of the separator, the fitment including a bore for carrying fluid from/to the central heating circuit to/from the separator;

a threaded connector disposed around the bore for securing the fitment to the or each port, the threaded connector having a knurled hand grip area for facilitating tightening of the connector by hand; and

a removable force transfer element receivable between the fitment and the threaded connector for transferring force between the threaded connector and the fitment, and, when installed on the fitment, the removable force transfer element being removable therefrom whilst the fitment and threaded connector remain fitted to the or each port.
