Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filling nozzles face issues with residual fluid discharge, particularly for high viscosity fluids, due to high back pressure and swirling at the discharge protection valve, leading to mechanical loading and reduced flow throughput.
Innovation Solution
The filling nozzle features a discharge protection valve with a first and second part-body that are movable relative to each other, creating additional fluid paths to improve flow dynamics and reduce back pressure, along with a magnetic interaction to ensure reliable closure and prevent residual fluid discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a discharge protection valve is provided to prevent residual fluid discharge, then residual fluid discharge is prevented, but high back pressure and swirling occur at the discharge protection valve
Solution Approach 1:
The discharge protection valve is divided into two separate part-bodies: a first part-body that moves relative to the valve seat to open a first fluid path, and a second part-body that moves relative to the first part-body to open a second fluid path. This segmentation allows the valve to manage back pressure while preventing residual discharge through coordinated movement of multiple components.
Solution Approach 2:
Both part-bodies are configured to be movable, creating dynamic fluid paths that can open and close based on pressure differentials. The first part-body responds to pressure from the main valve, while the second part-body responds to pressure from the first part-body, creating a dynamic system that adapts to varying flow conditions and reduces back pressure.
2Reliability
If a discharge protection valve is provided to prevent residual fluid discharge, then residual fluid discharge is prevented, but mechanical loading increases
Solution Approach 1:
By dividing the valve into two part-bodies, the mechanical load is distributed across multiple components rather than concentrated on a single valve body. The first part-body handles the primary sealing function while the second part-body provides additional sealing and back pressure reduction, sharing the mechanical burden.
Solution Approach 2:
The dynamic movement of both part-bodies allows the system to reduce mechanical loading by opening additional fluid paths when back pressure becomes excessive. The second part-body can move independently to create alternative flow routes, reducing the mechanical stress on any single component.
3Reliability
If a discharge protection valve is provided to prevent residual fluid discharge, then residual fluid discharge is prevented, but flow throughput is reduced
Solution Approach 1:
The valve system creates multiple fluid paths through the two part-bodies, allowing parallel flow routes that increase overall throughput. When the first fluid path is opened, the second fluid path can subsequently open to provide an additional flow channel, effectively doubling the capacity while maintaining discharge protection.
Solution Approach 2:
The dynamic opening of multiple fluid paths allows the system to optimize throughput based on operational conditions. The second fluid path activates when needed to boost flow capacity, and both paths work in conjunction to maximize productivity while maintaining reliable discharge protection through the coordinated movement of the part-bodies.

Implementation Method 2
an opening pressure generated by the fluid stream when the main valve is open is sufficient to open the discharge protection valve

AI summary
The invention relates to a filling valve for dispensing a fluid, comprising an inlet opening for connecting to a fluid supply line, an outlet end (12) which lies opposite the inlet opening, a main valve for controlling the flow of the fluid through the filling valve, and a leakage protection valve (13) which is arranged downstream of the main valve, comprising a valve seat (14) and a valve body (15, 16) which can be moved into a closed position in an upstream direction. According to the invention, the valve body (15, 16) has a first sub-body (15) and a second sub-body (16) which is designed to be movable relative to the first sub-body, wherein a first fluid path (17) can be released by a movement of the first sub-body (15) in a downstream direction relative to the valve seat (14), and a second fluid path (18) can be released by a movement of the second sub-body (16) in a downstream direction relative to the first sub-body (15). By virtue of the two-part valve body according to the invention, the flow of fluid through the filling valve can be optimized and the back pressure accumulating in front of the leakage protection valve can be reduced.
