Valve Tapping Sleeve Assembly for Leak-Proof Lined Host Pipes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conduit systems with lined host pipes face challenges in maintaining a secure and leak-proof connection between the valve and the liner, leading to potential fluid leakage and structural instability.
Innovation Solution
A fitting device assembly comprising a service sleeve and a reinforcing sleeve, with annular ratchets and cutouts, is used to secure the reinforcing sleeve within the service sleeve, forming seals with the liner and valve to prevent axial movement and ensure fluid communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a valve is installed in a lined host pipe, then fluid distribution function is achieved, but the connection between valve and liner may be unstable causing leakage
Solution Approach 1:
The reinforcing sleeve is inserted within the service sleeve, creating a nested configuration where the reinforcing sleeve provides internal support and the service sleeve provides external sealing. This nested structure ensures that the valve connection remains stable and leak-proof within the lined host pipe.
Solution Approach 2:
Annular ratchets with curved surfaces are formed on the service sleeve to engage with corresponding surfaces on the valve body. The curved geometry of these ratchets provides mechanical interlocking that prevents axial movement and ensures a secure, stable connection between the valve and the lined pipe.
2Stability of the object's composition
If the service sleeve is secured to the valve, then connection stability is improved, but axial movement may still occur causing potential leakage
Solution Approach 1:
Annular ratchets with curved engagement surfaces are formed on the service sleeve to mate with corresponding surfaces on the valve body. The curved geometry creates mechanical interlocking that prevents axial movement in both directions, ensuring the service sleeve remains securely positioned relative to the valve.
Solution Approach 2:
The reinforcing sleeve replicates the functional features of the service sleeve by forming identical annular ratchets on its outer surface. This ensures that both sleeves provide equivalent mechanical engagement with the valve,双重 preventing axial movement and enhancing connection stability.
3Strength
If the reinforcing sleeve is inserted within the service sleeve, then structural support is enhanced, but axial movement between sleeves may occur
Solution Approach 1:
Annular ratchets with curved surfaces are formed on both the service sleeve and reinforcing sleeve to engage with each other. The curved geometry of these interlocking ratchets prevents axial movement between the nested sleeves, ensuring they maintain stable relative positions while providing enhanced structural support.

AI summary
An apparatus, system, and method for tapping and reinforcing a valve of a liner lined host pipe with a fitting device assembly that includes a service sleeve having a flange, a cylindrical body, and an engaging end and a reinforcing sleeve having a flange, a cylindrical body, an engaging end having at least one annular ratchets configured to engage with the engaging end of the service sleeve in order to secure the service sleeve and the reinforcing sleeve together, and a plurality of cutouts in the cylindrical body. A cork assembly that includes the service sleeve and a cork having at least one radial appendage is inserted into the valve, then the host pipe is lined with a liner. The cork assembly is located, and the cork is removed from the cork assembly. The reinforcing sleeve is then installed into the service sleeve in the valve.
