Description

Technical Field

[0001] This application relates to the field of valve technology, and in particular to a magnetic check valve. Background Technology

[0002] A check valve, also known as a non-return valve, is a component used in pipelines to achieve a one-way shut-off function for the medium. It allows the medium to flow in one direction in the pipeline without backflow. For example, when a check valve is applied to a hydraulic system, it can prevent the oil flow from flowing in the opposite direction; when a check valve is applied to a pneumatic system, it can prevent the compressed air from flowing in the opposite direction.

[0003] Traditional check valves use a spring to drive the valve core, controlling the flow direction of the medium and providing a one-way seal. However, incorporating a spring into a check valve increases its design length and thus its weight. During use, the spring increases gas-liquid flow resistance, easily attracting impurities from the fluid medium and causing the check valve to jam, fail, or remain unopenable. Frequent vibrations during operation can also cause the spring to fail or lose elasticity. Over long-term storage, the spring may experience spring failure, corrosion and solidification, or displacement leading to spring failure, ultimately resulting in malfunctions such as the check valve failing to open, close properly, or remain unclosed.

[0004] Therefore, it is necessary to propose a brand-new magnetic check valve to solve the problems of traditional check valves. Utility Model Content

[0005] The purpose of this application is to provide a magnetically driven check valve, which solves the problems of traditional check valves that use springs to drive the valve core. Under the same specifications, the magnetically driven check valve of this application has a lower mass than the traditional spring check valve. Therefore, applying the magnetically driven check valve of this application to launch vehicles can improve the rocket's payload capacity. By using a magnet to drive the valve core, the magnet is less prone to failure or reduction in magnetic strength, which can effectively improve the reliability of the check valve and accurately control the opening force of the check valve.
