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 magnetic separator for use in a central heating system, the magnetic separator comprising a magnet and a sleeve around the magnet, in which the sleeve comprises first and second sleeve members, and a connection for connecting respective first ends of the first and second sleeve members together.

2. The magnetic separator of claim 1, wherein the first and second sleeve members are assembled as a two-part sleeve which is substantially sealed around the magnet against ingress of magnetic particles.

3. The magnetic separator of claim 1, wherein the first and second sleeve members are identical in shape.

4. The magnetic separator of claim 1, wherein the connection includes at least one resilient latch member on the first sleeve member and a co-operating recess on the second sleeve member, and at least one resilient latch member on the second sleeve member and a co-operating recess on the first sleeve member.

5. The magnetic separator of claim 1, wherein the connection includes two opposing resilient latch members and two opposing recesses on the first sleeve member, and two opposing resilient latch members and two opposing recesses on the second sleeve member, the latch members of the first sleeve member co-operating with the recesses of the second sleeve member and vice versa.

6. The magnetic separator of claim 1, wherein a roof and a tubular wall depending therefrom extend from a second end of each of the first and second sleeve members.

7. The magnetic separator of claim 6, wherein the roof is substantially conical.

8. The magnetic separator of claim 6, wherein a circular tray is adapted to connect with one of the roofs, to form a chamber.

9. The magnetic separator of claim 8, wherein the tray has a plurality of upstands for slowing flow within the chamber.

10. The magnetic separator of claim 9, wherein apertures are provided in the roof, and top ends of the upstands protrude through the apertures when the tray is attached.
