Energy-Saving Precision Pressure Adjusting Valve Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure adjusting valves suffer from inefficiencies in energy saving and precision due to the direct-operation flow control mechanism, which requires simultaneous opening of the main membrane aperture and overflow opening, leading to inflexibility and increased parts, making it difficult to balance pressure differences effectively.
Innovation Solution
The design incorporates multiple channels within the main body, including a feedback channel and a pressure regulation channel, with a steel ball and overflow tube, allowing for coordinated vertical movement of membranes to achieve balanced pressure adjustment without overflow, enabling fast and precise pressure regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a direct-operation flow control mechanism is used with simultaneous opening of main membrane aperture and overflow opening, then pressure adjustment can be achieved, but the device complexity increases and flexibility is reduced
Solution Approach 1:
The invention extracts the overflow function from the main membrane assembly by providing a separate overflow channel and overflow opening in the valve body. This allows the main membrane to focus solely on pressure regulation while the overflow mechanism independently handles excess pressure relief, thereby reducing the complexity of the main membrane structure and increasing operational flexibility.
Solution Approach 2:
The invention segments the pressure control functions by separating the main flow control path from the overflow path. The main membrane controls the primary flow through the main aperture, while a separate overflow membrane or opening handles excess pressure. This segmentation reduces the complexity of each individual component and improves overall system flexibility.
2Measurement precision
If multiple channels and coordinated membrane movement are implemented, then pressure adjustment precision is improved, but the device complexity increases
Solution Approach 1:
The invention implements a feedback mechanism where the overflow channel provides pressure feedback to the main membrane assembly. When pressure exceeds the set point, the overflow opens and reduces pressure, which is fed back to the main membrane to close the main aperture. This feedback loop ensures precise pressure control without requiring overly complex multi-channel structures.
Solution Approach 2:
The invention merges the pressure sensing and overflow functions into a coordinated system where the overflow mechanism and main membrane work together through shared pressure feedback. This integration achieves high precision pressure control while avoiding the complexity of completely separate control systems.
3Loss of energy
If the overflow tube and overflow opening are used for pressure balance, then energy loss is reduced, but the device complexity increases
Solution Approach 1:
The invention implements a self-service overflow system where the overflow channel automatically activates when pressure exceeds the set point without requiring external control. The pressure differential itself drives the overflow mechanism, and the system self-regulates by closing when pressure is reduced, minimizing pneumatic fluid loss without complex external control systems.
Solution Approach 2:
The invention uses pneumatic pressure differentials to drive the overflow mechanism and control the main membrane. The pressure differential between the inlet and outlet, combined with the overflow channel design, creates a self-regulating system that minimizes energy loss through controlled pneumatic fluid flow without requiring complex mechanical or electronic controls.

AI summary
An improved structure of an energy-saving precision pressure adjusting valve includes a main body in an interior of which a main membrane and a balance membrane are arranged. The main membrane is operable by an overflow tube and the balance membrane is operable by a pressure-adjusting stein, so that when pneumatic fluid enters the main body, through a channel, a feedback channel and a pressure regulation channel that communicate with each other, together with a feedback channel flow regulation hole and a steel ball arranged in the feedback channel, the pneumatic fluid is allowed to flow in one direction, in combination with stein covering rubber provided on the pressure-adjusting stein and membrane covering rubber provided on the main membrane, the flowing of the pneumatic fluid is made faster and the purpose of fast increase and decrease of pressure and high precision pressure output can be achieved.
