Ball Valve Testing Apparatus for Low Water Sensor Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing the integrity of low water sensor units in hot water boiler systems are cumbersome, time-consuming, and often require multiple personnel, posing risks due to potential steam buildup and damage from undetected low water levels.
Innovation Solution
A 2-piece threaded steel ball valve unit with a spring return mechanism allows for quick and safe testing of low water sensor units by temporarily impeding water flow during testing, enabling single-person operation within minutes, and automatically restoring flow once testing is complete.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional testing methods are used to test low water sensor units, then testing can be performed, but the process is cumbersome, time-consuming, and requires multiple personnel
Solution Approach 1:
The patent introduces an intermediary testing device that connects between the water source and the boiler system. This device includes a test port, valve mechanism, and flow control components that mediate the testing process, allowing sensor testing without draining the entire system or requiring complex manual procedures. The intermediary device simplifies the testing interface while maintaining safety and accuracy.
Solution Approach 2:
The patent extracts the testing function from the main boiler system into a separate, dedicated testing apparatus. By taking out the testing operations into an independent device with its own flow control and measurement capabilities, the system allows testing to be performed independently without affecting the main system operation or requiring system shutdown and draining.
2Reliability
If traditional testing methods are used, then testing can be performed, but there are risks due to potential steam buildup and damage from undetected low water levels
Solution Approach 1:
The patent implements preliminary actions by pre-configuring the testing device with flow control valves and pressure relief mechanisms before testing begins. The device is pre-prepared with test ports and connection points that allow immediate safe testing without requiring system draining or preparation time. Flow control is pre-established to prevent steam buildup before it can occur.
Solution Approach 2:
The testing device incorporates beforehand cushioning through pressure relief valves and controlled flow paths that prevent dangerous pressure and steam buildup during testing. These safety features are built into the device structure, providing automatic protection against steam explosions and water damage while enabling rapid testing without extended exposure to hazardous conditions.
3Ease of operation
If the heating system remains offline during testing, then sensor testing can be performed, but water flow to the heating system is interrupted
Solution Approach 1:
The patent segments the water flow path into separate channels: one for the main heating system and another for testing operations. The testing device includes bypass ports and dual-path flow control that allow the heating system to remain online and operational while testing is performed on the sensor. This segmentation enables independent operation of testing and heating functions without mutual interference.
Solution Approach 2:
The testing device maintains continuity of useful action by enabling both heating system operation and sensor testing to occur simultaneously. The bypass flow paths and parallel channel design ensure that water continues to flow to the heating system while a separate test stream is directed through the testing apparatus, eliminating system downtime and maintaining continuous heating service during testing.
