Magnetic Line Blind Valve for Leak-Free Grease Container Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the replacement of grease containers in lubrication installations, grease often escapes when the container is mounted or demounted, leading to inconvenience, waste, and potential air infiltration.
Innovation Solution
A line blind valve with a slide that can be displaced to close or open the passage between the inlet and outlet sections, equipped with magnets for secure sealing and a restricted movement mechanism to prevent grease leakage and air entry, allowing the container to be mounted upright without grease loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the grease container outlet is turned downwards during mounting, then the container can be mounted to the pump, but grease escapes from the container causing waste and inconvenience
Solution Approach 1:
The valve is closed before the mounting operation begins, preventing grease from escaping during the entire mounting process. The container can be oriented in any position without risking grease loss, as the closed valve seals the passage in advance.
Solution Approach 2:
The valve acts as an intermediary component between the grease container and the pump, controlling the flow path. By closing the valve, it mediates the mounting operation to occur without grease escape, and then opens to allow grease flow after mounting is complete.
2Ease of operation
If the grease container outlet is turned downwards during mounting, then the container can be mounted to the pump, but air infiltrates into the grease
Solution Approach 1:
The valve is closed before mounting, creating a sealed environment that prevents air from infiltrating the grease during the mounting operation and container repositioning.
Solution Approach 2:
The closed valve serves as a barrier that mediates between the external environment (where air could enter) and the grease system, preventing air infiltration during the mounting process.
3Reliability
If a valve is added to control grease flow, then grease leakage is prevented, but the device complexity increases
Solution Approach 1:
The valve mechanism is extracted as a separate, modular component that can be independently operated. This simplifies the overall system design and allows the valve to be maintained or replaced without affecting other components.
Solution Approach 2:
The valve is designed to be easily operated by the user themselves during the mounting process, requiring minimal additional equipment or complex control systems. The manual operation makes the system self-sufficient.
4Productivity
If the valve remains open during mounting, then grease can flow freely, but grease escapes and is wasted
Solution Approach 1:
The valve transitions from a static open state to a dynamic controlled state, allowing the system to adapt between grease flow and grease containment based on the operational phase (mounting vs. lubrication).
Solution Approach 2:
The valve is closed in advance during mounting to prevent grease escape, then opened after mounting is complete to restore full grease flow capability for normal lubrication operation.
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
Enables grease container replacement without leakage, ensuring no grease waste and preventing air infiltration, while maintaining a sealed environment to keep the grease clean and free from metal particles.
Implementation Method 1
By embedding magnets, as described below, in both the inlet and the outlet sections, these sections will be pulled towards each other and thereby about the upper and lower side of the slide.

AI summary
By mounting a line blind valve (2) between a grease container (1) and a grease lubrication pump (3) replacement and mounting of the grease container can take place without leak of grease during the mounting as the outlet section must turn downwards during the mounting. By providing the installation with a line blind valve this can block grease leakage during the mounting and thereafter be opened. The valve (2) includes a flat central part (10) with an opening (11) which part can be displaced in relation to an upper positioned inlet section (4) and a lower positioned outlet section (8) and by displacement of the slide open and close for passage. In order to keep these parts (4, 8, 10) together a magnet (6,7) is embedded in each of the two parts (4, 8) by which a sealed connection is secured with no air infiltration and metal particles held back.
