Pipe Break Valve Gap Throttle Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe break valve devices are complex, costly, and require multiple components, sealing means that can seize up over time, and necessitate accessible venting, making them economically inefficient and unreliable.
Innovation Solution
A compact pipe break valve device with a valve slide displaceable in the flow direction, using gaps as throttle ducts between the valve slide and housing, eliminating the need for sealing means and incorporating automatic venting through fluid flow, reducing components and manufacturing costs while ensuring reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional pipe break valve devices use multiple components and complex structure, then the valve can function reliably, but the device increases in cost and complexity
Solution Approach 1:
The patent extracts and removes multiple separate components including sealing elements, venting mechanisms, and complex throttle duct structures. The simplified design uses only the essential valve slide and gap structure, reducing component count while maintaining reliability through the fundamental pressure differential principle.
Solution Approach 2:
The gap structure serves multiple functions simultaneously: it eliminates the need for sealing means, provides automatic venting, and acts as the throttle duct system. This multi-functionality reduces the number of separate components needed while maintaining all necessary valve functions.
2Reliability
If traditional pipe break valve devices use complex throttle ducts and oil spaces, then pressure control is achieved, but the device weight and complexity increase
Solution Approach 1:
The patent extracts the complex separate oil spaces and throttle duct components, replacing them with a simplified gap structure between the valve slide and housing. This extraction maintains pressure control functionality while significantly reducing the amount of material and overall device weight.

Function Achieved in This Case
The solution results in a cost-effective, reliable, and easily installable pipe break valve device with reduced weight and complexity, eliminating the need for sealing means and accessible venting, ensuring permanent functionality and adaptability to various applications.
Implementation Method 1
The first duct region of the throttle ducts has a very small bore cross section which ultimately gives rise to a throttle effect
Implementation Method 2
a valve slide, displaceable counter to the action of elastic means, for shutting off the pipe break valve device

AI summary
A pipe break valve device includes a housing that has a recess continuous in a flow direction, a valve slide that is arranged displaceably in the flow direction in the recess, and a spatial volume of a throttle device that is arranged at least in regions between the outer wall of the valve slide and the inner wall of the housing. Throttle ducts that are present on the inlet side and on the outlet side are formed by a first gap and a second gap which are present in each case between the outer wall of the valve slide and the inner wall of the housing, and no sealing means are present between the inner wall of the housing and the outer wall of the valve slide.
