Impact-resistant pressure-relief fluid connector

Abstract

The invention relates to an impact-resistant pressure-relief fluid connector which comprises a socket and a plug. The socket comprises a main shell, a valve element, a fixing piece, a spring I, a sheath, a valve rod and a spring II, wherein the valve element and the fixing piece are arranged in the main shell, the spring I is arranged between the valve element and the fixing piece, the sheath is arranged in the valve element, the valve rod is arranged in a center hole of the sheath and a center hole of the fixing piece, and the spring II is arranged between the sheath and the fixing piece. A limiting table used for limiting the fixing piece during pressure relief is arranged on the inner wall of the main shell, an O-shaped sealing ring II is installed on the inner wall of the valve element, and in the non-insertion non-pressure-relief state, the valve element and the valve rod form a sealing structure through the O-shaped sealing ring II. The socket connector has a pressure-relief function, and does not cause instantaneous impacting on sealing rings during pressure relief, so that the sealing rings are not damaged, the springs run stably in the pressure relief process, inclining is not likely to happen, the pressure relief value is stable, protection of the sealing rings is facilitated, and the functions of large-flow impacting, online under-pressure plugging and unplugging and the like can be achieved.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to an impact-resistant pressure-releasing fluid connector. Background technique [0002] With the increasing integration of electronic systems and the increase of system heat density, the choice of heat dissipation methods tends to be liquid cooling technology. Liquid cooling technology has the advantages of low noise, small size and high heat dissipation efficiency. In order to facilitate the maintenance of the liquid cooling system, a modular design is often carried out. In the liquid cooling system, the fluid connector is one of the key components of the system, which has the function of quick disconnection of the module and fluid transmission. During the working process of the connector, in order to realize online plugging and unplugging without stopping the machine, the connector is required to have the function of pressure operation. At present, the fluid connectors with...

AI Technical Summary

Problems solved by technology

At present, the fluid connectors with the function of pressure operation, when the module is in the storage state and the pressure inside the module is increased by the temperature rise, the connector connected to the module does not have the function of automatic pressure relief, which may cause the module to collapse due to thermal expansion. Risk of damage; for fluid connectors with pressure relief function, when the pressure is released at a high pressure value, the O-ring at the pressure relief point is easily damaged by the instantaneous impact of high pressure due to lack of protection
