AI Technical Summary

Technical Problem

In the connected state, the fluid flow path pressure of the existing fluid connector is unbalanced, resulting in large energy loss. In addition, the valve core sealing ring protrudes out of the flow path, causing the flow path to narrow, thereby increasing energy loss.

Method used

The steel ball locking fluid connector is designed with a multi-stage flow channel structure and annular flow channel groove. Combined with the return spring structure of the plug and socket, it ensures a uniform flow channel cross-sectional area, reduces energy loss, and achieves a reliable connection through steel ball locking.

Benefits of technology

The pressure drop loss of the fluid connector is reduced, the smoothness of fluid circulation is improved, the processing process is simplified, the risk of fluid leakage is reduced, and the structure is simple and reliable.

Abstract

The utility model belongs to the technical field of fluid connectors, and particularly discloses a steel ball locking type fluid connector which comprises a plug and a socket, the plug comprises a plug installation sleeve, a plug valve element is arranged in the plug installation sleeve, and an elastic piece is arranged between the plug valve element and the plug installation sleeve. A plug valve core sealing ring is arranged between the plug valve core and the plug mounting sleeve; the socket comprises a plug mounting sleeve, a socket valve element is arranged in the plug mounting sleeve, a socket valve element sealing ring is arranged on the socket valve element, flow channels in the plug mounting sleeve sequentially comprise the first flow channel, the middle flow channel and the second flow channel, the first flow channel is located on the side away from the socket, and the diameter of the middle flow channel is larger than that of the first flow channel and that of the second flow channel. Two annular flow channel grooves are formed in the inner wall of the middle flow channel, and when the plug and the socket are assembled, the positions of the two flow channel grooves correspond to the positions of the plug valve element sealing ring and the socket valve element sealing ring respectively. According to the utility model, the voltage drop loss can be reduced.
