Check Valve Set Rod Locking for Open-Position Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for bypassing reverse flow check valves in fire-suppression systems are labor-intensive, costly, and complicated, especially when access is limited to spatially-confined areas.
Innovation Solution
The Hydra-Tap system mechanically secures a check valve in an open position using a set rod and rod locking component, allowing for maintenance and testing without removing the check valve, thereby simplifying the process and reducing labor and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual removal and flipping of the reverse flow check valve is performed, then maintenance and testing can be conducted, but the procedure becomes labor-intensive, costly, and complicated
Solution Approach 1:
The patent introduces an intermediary device consisting of a rod and locking mechanism that mediates between the maintenance personnel and the check valve. This intermediary tool allows opening and securing of the check valve without direct manual removal or flipping, thereby simplifying the maintenance procedure while reducing labor intensity and complexity
Solution Approach 2:
The locking mechanism is designed to preliminarily secure the check valve in the open position before maintenance activities begin. By预先 (in advance) establishing the open position and securing it with the locking mechanism, the need for complex manual operations during maintenance is eliminated, making the overall process simpler and more efficient
2Productivity
If the check valve is manually removed and flipped, then access is gained for maintenance, but labor time and costs increase significantly
Solution Approach 1:
The rod and locking mechanism serve as an intermediary tool that enables rapid opening and securing of the check valve without time-consuming manual removal and flipping operations. This intermediary device dramatically reduces maintenance downtime and increases productivity by providing a streamlined access method
Solution Approach 2:
The locking mechanism preliminarily prepares the check valve for maintenance by quickly securing it in the open position. This preliminary action eliminates the need for lengthy manual operations, thereby reducing maintenance downtime and improving overall productivity
3Ease of operation
If traditional bypass methods are used, then the check valve can be accessed, but the process becomes costly and labor-intensive
Solution Approach 1:
The patent introduces a cost-effective intermediary locking mechanism that provides easy access to the check valve without requiring expensive or labor-intensive traditional bypass methods. This intermediary device makes the access process both easier and more cost-effective
Solution Approach 2:
The locking mechanism is designed as a relatively simple, cost-effective device that can be easily installed and removed. Rather than requiring expensive permanent modifications or complex bypass systems, this affordable locking device provides the necessary access functionality at a lower cost

AI summary
A system including a set rod with a first and second end, and a curved portion, in which the first end is to be placed against a clapper inside a check valve, and a first connecting nipple having a first end to thread into a ball drip outlet of the check valve and a second end to receive a rod locking component. The rod locking component has a first end to attach with the second end of the first connecting nipple, a second end, and a lock mechanism positioned in a center portion to positionally fix the set rod in its position while placed against the clapper inside of the check valve. The set rod traverses through the ball drip outlet into the first connecting nipple, through the first connecting nipple into the rod locking component, and egresses through the second end of the rod locking component.
