Pressure Reducer Flange Structure to Prevent Compensation Hole Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure reducers are prone to clogging due to exposure of the pressure compensation hole to the external environment, which impairs the mobility of the piston rod and diaphragm, leading to functional safety issues and inefficient operation.
Innovation Solution
A pressure reducer design where the pressure compensation hole is enclosed by a flange, preventing direct exposure to external elements, and the threaded coupling between the pressure reducer body and flange acts as a filter to prevent foreign particles from entering, ensuring unobstructed mobility and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pressure compensation hole is exposed to the surrounding environment, then the piston rod and diaphragm can move freely, but the pressure compensation hole becomes clogged with dirt and foreign elements
Solution Approach 1:
The flange acts as an intermediary element that mediates between the pressure compensation hole and the external environment. It provides a protective barrier that prevents direct exposure to dirt and foreign elements while still allowing the pressure compensation function to operate through the threaded coupling mechanism.
Solution Approach 2:
The pressure compensation hole is nested within the threaded coupling structure of the flange assembly. The hole is positioned such that it is enclosed by the flange's internal geometry, creating a protected pathway that maintains functionality while preventing external contamination.
2Object-affected harmful factors
If the pressure compensation hole is enclosed by the flange, then the pressure compensation hole is protected from foreign elements, but the structure becomes more complex
Solution Approach 1:
The flange serves multiple functions simultaneously: it provides structural support for the pressure reducer assembly, creates the enclosing protection for the pressure compensation hole, and establishes the threaded coupling mechanism. This multi-functionality avoids the need for separate protective components, thereby maintaining structural simplicity.
Solution Approach 2:
The protective function for the pressure compensation hole is merged into the flange structure itself. Rather than adding a separate protective cover or housing, the flange's design inherently provides both structural and protective roles, combining multiple functions into a single integrated component.
3Object-affected harmful factors
If a filter screen is added to protect the pressure compensation hole, then clogging is prevented, but the device requires additional attachments
Solution Approach 1:
The threaded coupling structure of the flange provides self-service protection against clogging. The threaded geometry itself acts as a mechanical filter that prevents foreign elements from entering the pressure compensation hole, eliminating the need for separate filter screens or protective attachments while maintaining clogging prevention functionality.

AI summary
A pressure reducer (100) for reducing a fluid pressure includes a pressure reducer body (110) defining at least one pressure reducer chamber (120). The pressure reducer chamber (120) includes an inlet section (122) and an outlet section (124) fluidly coupled with the inlet section (122). The pressure reducer chamber (120) further includes a spring-operated piston rod (121) and a sealing element (128) operatively coupled with the piston rod (121). A flange (132) is sealing coupled with the pressure reducer body (110). The pressure reducer body (110) defines a pressure compensation hole (114). The pressure reducer (100) is characterized in that the pressure reducer body (110) has a first threaded portion (112), and the flange (132) has a second threaded portion (134) such that the pressure reducer body (110) and the flange (132) are threadedly coupled. The pressure compensation hole (114) is disposed in the first threaded portion (112) of the pressure reducer body (110) such that the flange (132) is adapted to enclose the pressure compensation hole (114) when the flange (132) is coupled to the pressure reducer body (110).
