Summary of the Inventive Concept

This inventive concept leverages the core technology of the original check valve patent to address fluid flow and contamination issues in various industries, including agriculture, industrial pipelines, fuel management, fire suppression, and chemical processing.

Background and Problem Solved

The original check valve patent primarily focused on medical applications, particularly intravenous sets. However, the limitations of this patent in addressing fluid flow and contamination issues in other industries are evident. The new inventive concept addresses these limitations by applying the core technology to diverse industries, providing a robust and reliable solution for ensuring fluid flow and reducing contamination.

Detailed Description of the Inventive Concept

The advanced check valve technology incorporates a wiping extension that removes particulate from the check valve, ensuring fluid flow and reducing contamination. This technology can be applied to various industries, such as agricultural irrigation systems, industrial pipelines, fuel management systems, fire suppression systems, and chemical processing systems. The wiping extension's ability to unclog or dislodge particulate from the valve member enables the removal of particulate from the check valve, thereby maintaining fluid flow and reducing contamination. The new claims provide a comprehensive solution for addressing fluid flow and contamination issues in these industries.

Novelty and Inventive Step

The new inventive concept's novelty lies in its application to diverse industries, which was not originally considered in the original patent. The inventive step is the recognition of the core technology's potential in addressing fluid flow and contamination issues beyond medical applications, and the development of new claims that cater to these industries.

Alternative Embodiments and Variations

Alternative embodiments of the advanced check valve technology could include variations in the wiping extension's design, material, or operation. For example, the wiping extension could be modified to accommodate different fluid types, flow rates, or pressure conditions. Additionally, the check valve could be integrated with sensors or monitoring systems to provide real-time feedback on fluid flow and contamination levels.

Potential Commercial Applications and Market

The advanced check valve technology has significant commercial potential in various industries, including agriculture, industrial processing, fuel management, fire suppression, and chemical processing. The technology's ability to ensure fluid flow and reduce contamination can lead to increased efficiency, reduced downtime, and improved product quality. The target market includes manufacturers, suppliers, and end-users in these industries, who can benefit from the advanced check valve technology's robust and reliable performance.
