Appl. No.:

11/807072

Inventors:

David B. Crompton - Tiverton RI, US

Assignee:

Quick Fitting, Inc. - East Providence RI

International Classification:

F16L 19/06

US Classification:

285340, 285342, 285 39

Abstract:

A pipe fitting assembly package and fastening ring removal tool allow re-use and repair of push-fit piping fittings and valves without damage to the fitting or valve elements or the pipe. The quick connection pipe fitting assembly package of the present invention employs a threaded retaining cap that when removed, exposes the clamping, sealing and fastening mechanism of the fitting or valve. In one embodiment, the present invention further includes a removable packing gland mounted on a body about an axis of an orifice. The fastening ring removal device provided as part of the present invention is manually pushed onto the cylindrical object and is capable of expanding to traverse over the installed fastening ring. The fastening ring removal device includes a parallel angular surface to lift the fastening ring off of the pipe member. In one embodiment of the present invention, the removal device has a plurality of cut areas or slits extending axially along its surface to allow for the expansion of the upper rim portion of the fastener removal tool as it slides over a remaining fastening ring.

Inventors:

David B. Crompton - Tiverton RI, US

Assignee:

Quick Fitting, Inc. - East Providence RI

International Classification:

F16K 27/00

US Classification:

137359, 137316, 13731513

Abstract:

The present invention provides an integrated valve, push connection and push release components, and a valve mounting assembly for use on fluid, air or gas applications. The invention allows for the installation of the valve by sliding the valve over the supply tube/piping or pushing the tube/piping into the valve. Once connected, an o-ring seals the connection, a packing gland applies energy to the o-ring seal maintaining constant, even pressure across the seal, and a grip ring applies opposing energy to prevent the disconnection of the assembly. The quick connection assembly is retained by a retaining cap, which applies constant, positive force on the sealing surface.
