US 2025/0084929 A1 · VALVE CORE WITH MICROPOROUS STRUCTURE AND SOLENOID VALVE USING VALVE CORE

Abstract

Disclosed are a valve core with a microporous structure and a solenoid valve using the valve core. The solenoid valve comprises a valve body, an electromagnetic component, an elastic component and a valve core. The valve core comprises a sealing component and a microporous material. The valve core is arranged in the valve body, the elastic component is arranged between the valve core and the electromagnetic component, a flow channel is arranged on the valve body, the microporous material is matched with a flow channel on the valve body. In this design, the sealing component and the microporous material are integrated into a unified structure, forming a monolithic valve core. The control of flow rate and pressure is entirely dependent on the compression amount of the microporous material, revolutionizing the traditional flow control method of the solenoid valve. This approach enhances the precision of flow control within a certain range.

Dependent claims

A valve core with a microporous structure, comprising a sealing component and a microporous material, wherein the sealing component is located at an upper end of the microporous material, and the sealing component seals a top of the microporous material;

and the microporous material is a flexible material with a microporous structure, the microporous material allows fluid to pass through, and the microporous material is arranged to change a fluid flow rate by varying a degree of compressive deformation.

A solenoid valve using a valve core with a microporous structure, comprising a valve body, an electromagnetic component, an elastic component and a valve core;

wherein the valve core comprises a sealing component and a microporous material, the sealing component is located at an upper end of the microporous material, and the sealing component seals a top of the microporous material;
the microporous material is a flexible material with a microporous structure, and the microporous material allows fluid to pass through;
the valve core is arranged in the valve body, the elastic component is arranged between the valve core and the electromagnetic component, a flow channel is arranged on the valve body, and the microporous material is matched with a flow channel on the valve body;
when the electromagnetic component is not energized, the elastic component presses the valve core, such that the microporous material is in a compressed state, and the microporous material seals the flow channel on the valve body;
when the electromagnetic component is energized, the valve core overcomes the elastic force of the elastic component to release the microporous material, allowing the flow channel on the valve body to be open;
and
the electromagnetic component changes a compression amount of the microporous material by varying a magnitude of a magnetic attraction force, thereby controlling a flow rate of the flow channel on the valve body.
