Low-flow-resistance under-pressure plugging fluid connector

Abstract

The invention discloses a low-flow-resistance pressurized plugging fluid connector which comprises a plug and a socket matched with the plug, and the front end of the plug and the front end of the socket are plugging ends. The plug comprises a first mounting shell, a first sealing ring, a first spring, a first axial sliding sealing assembly and a plug-in shell; the first axial sliding sealing assembly is assembled at the front end in the first mounting shell in a sliding manner; the socket comprises a second mounting shell, a third sealing ring group, a fourth sealing ring, a fifth sealing ring, an axial fixed sealing assembly, a third spring, a guide shell and a second axial sliding sealing assembly; by means of the structural design, in the working process, the sealing ring at the valve element at one end of the switch flow channel is exposed in fluid, and the sealing ring at the valve element at the other end is not exposed in the fluid, so that the sealing ring at the position cannot be washed away when the flow speed of the fluid is large; the service life of the sealing ring is prolonged, and the number of times of under-pressure plugging and unplugging of the connector is increased.

Description

technical field [0001] The invention belongs to the technical field of fluid connectors, and in particular relates to a low-flow resistance plug-in-pull fluid connector with pressure. Background technique [0002] With the continuous development of electronic components in equipment towards high frequency, high density and high integration, the problem of how to achieve efficient heat dissipation in equipment has become more and more prominent. Liquid cooling technology has become the preferred solution to this problem. Liquid cooling technology has been widely used in aviation, aerospace, electronics, ships, communications, wind power, electric vehicles, data centers and other fields. [0003] With the increasing development of technology, electronic equipment tends to be highly reliable, and a highly reliable fluid connector is urgently needed to realize the transmission of fluid between the cooled module and the chassis. However, such existing connectors have the followin...

AI Technical Summary

Problems solved by technology

[0004] 1. The flow resistance of the fluid connector is relatively large, and the heat dissipation effect is not ideal

Especially in the range where the axial floating ratio is large, it is not easy to meet the low flow resistance

[0005] 2. During the process of opening or closing the flow channel of the fluid connector, the O-ring is affected by the pressure of the water flow and is easily washed off and deformed, resulting in seal failure;

[0006] 3. Existing fluid connectors use a single sealing component as the plug-in end and the socket-in-connection end to protect the sealing parts. The sealing component is installed in the plug in an axially movable manner through a spring, so as to realize the free state when the spring pushes Under the action, the fluid channel of the plug is blocked, and when the plug and socket are inserted, they move axially and form a flow channel with the inner wall of the housing for the liquid to pass through. When the flow channel is opened, the O-ring in the center of the fluid channel of the plug / socket is not blocked Protection, under the impact of high-speed liquid, deformation, shedding, adhesion of impurities lead to leakage and product failure
