Quick coupling male component capable of automatically relieving pressure

Abstract

The invention belongs to the technology of a fluid transmission connector in the field of electronic liquid heat dissipation, and relates to a quick coupling male component capable of automatically relieving pressure. The quick coupling male component comprises a connecting nut, a male disk shell II, an O-shaped rubber ring I, a male disk shell I and an O-shaped rubber ring II. The quick couplingmale component is characterized by also comprising a cylinder spring I, a sealing rod, a cylinder spring II, a snap spring and a sealing block. When the inner pressure of the quick coupling is lower than a designed pressure relief value, the sealing rod and the sealing block are integrated and reach an effect of sealing. When the inner pressure of the quick coupling reaches the designed pressure relief value, the sealing rod is separated from the sealing block and protrudes forwards to realize a function of automatic pressure relief. By using the fluid connector capable of automatically relieving pressure, the automatically relieving pressure can improve the safety of a liquid cooling system, greatly reduces the phenomenon that a module is broken and damaged due to pressure jump or temperature change, further improves the stability and reliability of the system, and reduces financial loss.

Description

technical field [0001] The invention belongs to fluid transmission connector technology in the field of electronic liquid heat dissipation, and relates to a quick connector male assembly capable of automatic pressure relief. Background technique [0002] 1. During the operation or debugging of the liquid cooling system, it is often necessary to maintain the liquid cooling module in the system. After the shutdown, the pressure in the liquid cooling module may not be completely removed. High, the liquid inside the module expands when heated, the pressure increases sharply, and the pressure is enough to burst the module; [0003] 2. The liquid cooling system operates under the rated pressure, and the supply pressure of the system may be unstable. When the sudden change in pressure is greater than the safe pressure of the module, the module will be damaged and bulged. [0004] In the above two application environments, the internal pressure of the module rises sharply. Since th...

[0003] 2. The liquid cooling system operates under the rated pressure, and the system may have unstable supply pressure. When the pressure mutation is greater than the safe pressure of the module, the module will be damaged and bulged.

[0007] Due to the small internal space and large structural restrictions of the quick connector male assembly, the current blind-mating quick connector male assembly does not have a self-relieving function in the entire industry

However, in the industry, the self-relieving function of the ball-locking quick connector male head component is only realized by domestic manufacturers on products with an effective diameter greater than 10mm. The specific solution is to hollow out the inside of the sealed terminal and install a spring inside the sealed terminal. O-shaped sealing rubber ring, spring and other parts are realized. The biggest problem of this solution is that it can only be realized when the structural space of the quick connector male head assembly is sufficient. Products with an effective diameter below 10mm cannot realize the self-relieving function.
