Clawed Pressure Relief Valve Assembly With Pre-Calibrated Springs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure relief valves require additional adjustment pieces and screwing processes during assembly, and lack integrated pressure indicators, necessitating external pressure gauges for setting the desired pressure level.
Innovation Solution
The pressure relief valve features a clawed rear cover made of recyclable thermoplastic, eliminates screwing processes through a clawed structure, and includes pre-measured springs for precise assembly without further adjustments, with a membrane providing 100% sealing and acting as an O-ring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional valves use screwing processes and adjustment pieces during assembly, then the valve can be adjusted to proper pressure, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The patent combines the rear cover attachment function and the membrane sealing function into a single integrated clawed structure. The clawed rear cover simultaneously secures the membrane and attaches the cover to the body, eliminating the need for separate screws and washers. This merging of functions directly reduces the number of parts and simplifies the assembly process while maintaining proper valve operation.
Solution Approach 2:
The patent extracts and eliminates unnecessary adjustment pieces from the assembly process. By pre-measuring springs during manufacturing to ensure they fall within specific value ranges, the need for field adjustments and additional adjustment pieces is removed. This extraction of the adjustment function from the assembly stage resolves the contradiction by simplifying assembly without compromising pressure control capability.
2Manufacturing precision
If conventional valves require adjustment pieces for pressure setting, then the valve can be calibrated to desired pressure, but additional parts and adjustment steps are needed
Solution Approach 1:
The patent applies preliminary action by pre-measuring and pre-calibrating springs during the manufacturing process. Springs are measured to ensure they fall within specific value ranges that guarantee proper valve operation at the desired pressure. This preliminary calibration eliminates the need for field adjustments and additional adjustment pieces, resolving the contradiction by achieving precise pressure control through manufacturing precision rather than through complex assembly adjustments.
3Ease of manufacture
If conventional valves use multiple separate components, then each component can be optimized independently, but the overall assembly becomes more complex
Solution Approach 1:
The patent merges the rear cover and membrane retainer functions into a single integrated clawed structure. This unified component is manufactured as one piece, allowing optimization of the overall assembly rather than coordinating multiple separate components. The integrated design simplifies the assembly process, enabling faster installation while maintaining the ability to optimize the valve's performance characteristics through the unified structure's design parameters.

AI summary
In general terms, the present invention relates to a safety valve or a pressure relief valve (PRV) that is developed to be used in combination boilers and similar appliances and utilized for the purpose of controlling or limiting system pressure. Relief valves are generally used as safety devices in systems where fluid pressure is important, and they reduce the system pressure either by discharging fluid from the system or simply by interrupting the fluid conveyance in case of an emergency when there is an increase in pressure. The present invention relates to a pressure relief valve, the rear cover of which is attached to the body by means of a clawed structure and manufactured from entirely recyclable thermoplastic material.
