Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distributor valves have complex structures with numerous separate components, leading to complicated assembly, high susceptibility to errors, and difficulty in sealing due to multiple housing parts.
Innovation Solution
A distributor valve with an integrated flow measuring unit, where the regulating unit and flow rate indicator are arranged downstream of a single branch in the main pipe, simplifying the structure and assembly by using a one-piece housing design, and incorporating a rotating regulating plug and flow measuring body for precise flow control and measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-part distributor valve housing with separate first and second housing parts is used, then the flow control and measurement functions can be implemented, but the structure becomes complex and assembly becomes complicated
Solution Approach 1:
The patent merges the first housing part and second housing part into a single integrated valve body. The flow control unit and flow measurement unit are combined within this single structure, eliminating the need for separate housing parts and reducing assembly complexity while maintaining both flow control and measurement functions.
Solution Approach 2:
The integrated valve body serves multiple functions simultaneously: it acts as the main structural housing, contains the flow control mechanism with regulating spindle, accommodates the flow measurement unit with float indicator, and provides sealing surfaces. This multi-functional design reduces the number of components needed.
2Adaptability or versatility
If multiple separate housing parts are used, then flow control and measurement are possible, but the susceptibility to errors increases
Solution Approach 1:
By combining multiple separate components into a single integrated valve body, the patent reduces the number of interfaces and connection points where errors can occur. The integrated design minimizes assembly variations and ensures consistent positioning of the flow control and measurement elements.
3Adaptability or versatility
If multiple housing parts are used, then flow control and measurement functions are achieved, but sealing becomes difficult
Solution Approach 1:
The integration of housing parts into a single valve body eliminates the need for seals between separate housing components. The patent only requires sealing at the interface between the regulating spindle and the valve body, and between the flow measurement unit and the valve body, significantly reducing sealing complexity.
4Adaptability or versatility
If a complex multi-component structure is used, then flow control and measurement are implemented, but the assembly process becomes complicated
Solution Approach 1:
The patent combines multiple components into a pre-assembled integrated valve body that can be installed as a single unit. The flow control unit and flow measurement unit are already positioned and secured within the valve body during manufacturing, eliminating the need for complex on-site assembly of multiple separate parts.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The simplified design reduces assembly complexity, minimizes leakage risks, and enhances sealing, while optimizing flow rates with a streamlined flow path, making the distributor valve easier to install and maintain with reduced pressure loss and susceptibility to contamination.
Implementation Method 1
a flow measuring body (6) with a paddle (6.1), a pointer (6.2) spaced apart from the paddle (6.1) in the axial direction and a rotationally symmetrical disc (6.3) arranged between the paddle (6.1) and the pointer (6.2), which is rotatably mounted in the second housing part (4.3) about a second axis of rotation (x2)
