Abstract

An apparatus for unsealing a pipe in a pipe assembly is disclosed. The apparatus has a seal for minimizing leakage from the pipe and a spring attaching to both the seal and the pipe assembly. If the seal is to be removed, a spring force of the spring acts against and moves the seal for removal of the seal.

Claims (28)

1. An apparatus for unsealing a pipe in a pipe assembly, said apparatus comprising:

a holder defining a bore for receiving a pipe,

a seal disposed in said bore for minimizing leakage from said holder,

a verification cartridge disposed in said bore, and

a verification clip that cooperates with said verification cartridge to seal the pipe within the holder such that when said verification clip and said pipe are removed from said holder, a spring force of said verification cartridge acts against an inner surface of said bore and moves each portion of said seal from a sealed position within said bore to an unsealed position within said bore for removal of said seal from said bore, and wherein said spring force is aligned with a longitudinal axis of said pipe.

2. The apparatus of claim 1 , wherein said spring further comprises:

a flexible flange disposed upon said verification cartridge, said flexible flange compressing against said inner surface of said bore if a force is applied to said spring when said flange is adjacent to said inner surface and decompresses if said force is removed therefrom.

3. The apparatus of claim 2 , wherein a portion of said flexible flange is oblique to the longitudinal axis of said pipe when said pipe is sealed.

4. The apparatus of claim 1 , wherein said a portion of said inner surface angles towards an exit port of said bore.

5. The apparatus of claim 1 , wherein said holder is a valve.

6. The apparatus for unsealing a pipe in a pipe assembly of claim 3 , wherein a portion of said inner surface is oblique to the longitudinal axis of the pipe.

7. An apparatus for unsealing a pipe in a pipe assembly, said apparatus comprising:

a holder defining a bore for receiving a pipe,

at least one seal for receiving said pipe there through and minimizing leakage from said pipe within said holder,

a verification cartridge whereupon said at least one seal is disposed, said verification cartridge selectively located in said bore,

a verification clip that cooperates with said verification cartridge to seal the pipe within said holder, and

a spring defined by said verification cartridge wherein when said at least one seal is to be removed, a spring force of said verification cartridge acts against an inner surface of said bore after removal of said verification clip from said holder and moves each portion of said at least one seal from a sealed position within said bore to an unsealed position within said bore for removal of said seal from said bore, and wherein said spring force is aligned with a longitudinal axis of said pipe.

8. The apparatus of claim 7 , wherein said spring further comprises:

a flexible flange defined by said cartridge, said flange compressing against said inner surface of said bore if a force is applied to said spring when said flange is adjacent to said inner surface and decompressing if said force is removed therefrom.

9. The apparatus of claim 7 , wherein a portion of said flexible flange is oblique to the longitudinal axis of said pipe when said pipe is sealed.

10. The apparatus of claim 7 , wherein a portion of said surface angles towards an exit port of said bore.

11. The apparatus of claim 7 , wherein said holder is a valve.

12. The apparatus for unsealing a pipe in a pipe assembly of claim 9 , wherein a portion of said inner surface is oblique to the longitudinal axis of the pipe.

13. A method for removing a seal encircling a pipe from a pipe holder, said method comprising:

providing a verification cartridge whereupon at least one seal is disposed, said verification cartridge for being disposed within a bore of a pipe holder;

providing a spring integral with said verification cartridge;

removing an obstruction to said verification cartridge whereby said spring acts against an inner surface of said bore to move each portion of said at least one seal from a sealed position within said bore to an unsealed position within said bore by exerting a spring force aligned with a longitudinal axis of said pipe; and

removing said verification cartridge and said at least one seal from said bore.
