Title:
VALVE CORE COMPONENT AND MULTI-WAY VALVE
Document Type and Number:
WIPO Patent Application WO/2023/143204
Kind Code:
A1
Abstract:
A valve core component and a multi-way valve. The valve core component comprises: an inner cylinder structure (10), the inner cylinder structure (10) being internally provided with a circulation channel (11) extending in an axial direction of the inner cylinder structure, and the side wall of the inner cylinder structure (10) being provided with a first through hole (12) and a second through hole (13) which are communicated with the circulation channel (11); and an outer cylinder structure (20), surrounding the inner cylinder structure (10), the outer cylinder structure (20) having a multi-layer circulation cavity (21) in the axial direction of the inner cylinder structure (10), each layer of circulation cavity (21) being divided into a plurality of sub-cavities in a circumferential direction of the inner cylinder structure (10), and an opening of each sub-cavity facing the outside of the valve core component. The first through hole (12) is communicated with one sub-cavity in one layer of the circulation cavity (21), and the second through hole (13) is communicated with one sub-cavity in another layer of the circulation cavity (21). According to the valve core component, the inner cylinder structure and the outer cylinder structure are communicated by means of the first through hole, the circulation channel and the second through hole of the inner cylinder structure, so that cross-layer communication of the multi-layer circulation cavity of the valve core component is achieved by means of the inner cylinder structure, and the performance and the application range of the valve core component are improved.
