Pressure Relief Valve Claw Assembly for Precise Pressure Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure relief valves require additional adjustments and components during assembly, which can lead to inefficiencies and potential misalignment, and they lack indicators for precise pressure setting, necessitating external pressure gauges for correct calibration.
Innovation Solution
A pressure relief valve with a clawed structure for assembly and made from recyclable thermoplastic material, featuring individually measured springs and a membrane that functions as an O-ring for 100% sealing, eliminating the need for washers and screws, and allowing for precise pressure control without additional adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional valves use screws and washers for assembly, then the connection is secure, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple fastening functions into a single integrated clawed structure on the rear cover. The claws serve both as mounting lugs for attachment to the body and as retention mechanisms for the membrane, eliminating the need for separate screws and washers. This merging of functions directly reduces component count and simplifies assembly while maintaining secure connection.
Solution Approach 2:
The invention extracts and eliminates unnecessary components (screws and washers) from the assembly by replacing them with an integrated clawed structure. The claws are directly formed on the rear cover, taking out the need for separate fastening elements and reducing overall device complexity while preserving the secure mounting function.
2Manufacturing precision
If springs are adjusted during assembly, then the valve opens at the correct pressure, but additional adjustment pieces and time are required
Solution Approach 1:
The springs are pre-adjusted to specific pressure values during the manufacturing process before assembly. This preliminary action ensures that when the springs are installed in the valve, they are already calibrated to the correct pressure settings, eliminating the need for field adjustments and reducing assembly time while maintaining pressure setting accuracy.
Solution Approach 2:
The springs are manufactured with built-in pressure calibration features that allow them to self-regulate to the correct opening pressure based on their pre-set characteristics. This self-service capability eliminates the need for external adjustment mechanisms or manual calibration during assembly, reducing both time and complexity.
3Reliability
If a washer is used under the membrane, then the sealing is adequate, but the assembly requires additional components and steps
Solution Approach 1:
The patent merges the sealing function traditionally provided by a washer with the membrane itself. The membrane is designed with an integrated sealing edge that directly contacts the valve body seating surface, combining the sealing function with the membrane component and eliminating the need for a separate washer while maintaining sealing effectiveness.
Solution Approach 2:
The invention extracts and removes the washer component from the assembly by integrating its sealing function directly into the membrane design. The membrane's peripheral edge is shaped to provide the sealing contact, taking out the unnecessary washer and reducing component count while preserving the required sealing reliability.

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.
