Valve Test Cylinder for Isolating Pipe Leaks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional temperature control valves in bathroom equipment do not allow for precise identification of water leakage in individual pipes during pressure tests, making it difficult to locate the exact position of leaks in the pipe system.
Innovation Solution
A test cylinder and connection structure are introduced, which include a body with a holder, accommodation chamber, and separate inlets and outlets for cold and hot water, allowing for the formation of multiple closed pipe systems for targeted pressure testing, enabling the isolation and identification of leaks in either the cold-water or hot-water pipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional test lid is used to perform pressure test on the entire pipe system, then the pressure test can be executed, but the exact position of water leakage cannot be confirmed
Solution Approach 1:
The test cylinder is divided into multiple independent testing chambers (first testing chamber for cold-water pipe, second testing chamber for hot-water pipe) that can be separately configured and tested. This segmentation allows isolation of individual pipe systems to precisely identify leakage positions without testing the entire system as one unit.
Solution Approach 2:
The test cylinder acts as an intermediary device that connects to and isolates specific sections of the pipe system (cold-water or hot-water pipes) through configurable connection structures. This intermediary structure enables targeted pressure testing of individual pipes while maintaining the ability to test the overall system when needed.
2Reliability
If the entire pipe system is tested as one closed system, then the pressure test can be performed, but the specific pipe with leakage cannot be identified
Solution Approach 1:
The testing system is segmented into multiple independent testing chambers, each capable of isolating and testing specific pipe sections. The first testing chamber tests the cold-water pipe while the second testing chamber tests the hot-water pipe, allowing leakage location information to be preserved by identifying which specific chamber shows pressure loss.
Solution Approach 2:
The connection structure between the test cylinder and pipe system is dynamic and configurable, allowing the system to adapt between testing the entire pipe system as one unit or isolating and testing individual pipe sections. This dynamic configuration capability enables flexible testing strategies to maintain both reliability and location information.

AI summary
A test cylinder of a valve assembly is mounted a body of the valve assembly, the body includes a holder containing an accommodation chamber, a bottom fence formed, and a cold-water inlet and a hot-water inlet which respectively communicate with a cold-water inflow pipe and a hot-water inflow pipe of the body. The accommodation chamber has a first mixing-water outlet and a second mixing-water outlet which individually communicate with a first outflow pipe and a second outflow pipe. The test cylinder includes a peripheral fence, a first orifice, an edge fence, and a first cavity defined. The peripheral fence has at least one second orifice, a second cavity, and an internal surround portion of the accommodation chamber. The edge fence has a closing portion extending from an outer wall thereof and has a conduit defined in the edge fence.
