US Patent:

54801222, Jan 2, 1996

Filed:

Aug 23, 1993

Appl. No.:

8/110568

Inventors:

Paul J. Barker - Old Greenwich CT

International Classification:

F16K 322

US Classification:

251148

Abstract:

A trouble-shooting shut-off valve includes an inlet-tail-tube mountable directly into a compression-fitting outlet socket of a defective shut-off valve, thus positioning the trouble-shooting valve immediately downstream from the defective valve in line in series with the defective valve. An inlet-tail-tube fitting is mounted onto an upstream end of the valve housing as a component of the valve. This fitting has an axial bore forming an upstream extension of an inlet passage in the valve housing. The inlet-tail-tube projects axially from this fitting adapted for insertion directly into such a socket in the defective valve. The inlet-tail-tube has a diameter equal to the outside diameter of flexible plumbing tubing, referred to as flex tube, and is formed of material suitable for making a compression connection thereto. An inlet end termination of the inlet-tail-tube is flat for seating down squarely into the outlet socket of the defective valve. A downstream end of the valve housing has an exteriorly-threaded boss with a valve outlet passage extending through this boss to a downstream termination of the boss.

Abstract:

A trouble-shooting, one-quarter-turn quick shut-off valve is mountable directly to a compression-type fitting outlet of a defective shut-off valve in series with the defective valve so that the quick shut-off valve becomes located immediately downstream from the defective valve. Projecting from an inlet end of a housing of the quick shut-off valve is an inlet-tail-tube having an inlet passage extending axially through the inlet-tail-tube. This inlet-tail-tube is adapted for insertion directly into a socket in a compression-type fitting outlet of a shut-off valve. The inlet-tail-tube is made of suitable material for making a compression connection thereto, and the outside diameter of this inlet-tail-tube is equal to an outside diameter often used for flexible plumbing tubing of the type adapted for insertion into a socket of a compression-type fitting for enabling a compression connection to be made between the inlet-tail-tube and the compression-type socket into which the inlet-tail-tube has been inserted. The inlet-tail-tube is shown provided on an inlet fitting having an exteriorly threaded downstream projection screwed into a socket on the inlet end of the valve housing with a recess holding a seat seal against a quarter-turn rotatable valve element. This valve is also adapted to serve as a high-quality, convenient-to-install, premium valve unit for use in a new plumbing installation.
