Title:
ELECTROMAGNETIC DIRECTIONAL CONTROL VALVE
Document Type and Number:
WIPO Patent Application WO/2022/161456
Kind Code:
A1
Abstract:
An electromagnetic directional control valve, comprising a valve body part. The valve body part comprises a valve body main body part (10), a first sleeve part (40), and a second sleeve part (50), the first sleeve part (40) is fixedly connected to the valve body main body part (10), and the second sleeve part (50) is fixedly connected to the valve body main body part (10); the valve body main body part (10) further comprises a plate-shaped part (11) and a surrounding part (12); the plate-shaped part (11) and the surrounding part (12) are fixedly connected or are integrally formed; the shape of the longitudinal cross section of the valve body main body part (10) is different from that of the longitudinal cross section of the first sleeve part (40), and the shape of the longitudinal cross section of the valve body main body part (10) is different from the shape of the longitudinal cross section of the second sleeve part (50); the area defined by the maximum longitudinal cross section of the valve body main body part (10) is greater than the area defined by the longitudinal cross section of the first sleeve part (40), and the area defined by the maximum longitudinal cross section of the valve body main body part (10) is greater than the area defined by the longitudinal cross section of the second sleeve part (50). The manufacturing cost of the valve body part can be relatively reduced.
