Modular pressure relief assembly capable of automatically relieving pressure

Abstract

The invention belongs to the technical field of sealing and pressure relief in liquid cooling systems and relates to a modular pressure relief assembly capable of automatically relieving pressure. Themodular pressure relief assembly is characterized in that the modular pressure relief assembly comprise a shell, a positioning block, a spring and a ball bead; the shell is hollow inside; one end ofthe shell is open; a through hole correspondingly communicated with the inner cavity of the shell is formed in the other end of the shell; an annular boss coaxial with the through hole is arranged ata position, corresponding to the through hole, in the cavity of the shell; the positioning block is arranged in the open end of the shell in a sealed mode; a pressure relief cavity is formed in the end surface of the end, corresponding to the through hole, of the positioning block; a liquid discharging hole correspondingly communicated with the pressure relief cavity is formed in the end surface of the other end of the positioning block; the ball bead is movably connected to the edge of the opening of the pressure relief cavity; a spring of which two ends correspondingly abut against the cavity bottom of the pressure relief cavity and the ball bead is arranged in the pressure relief cavity; and the top end, far away from the spring, of the ball bead can correspondingly abut against the annular boss. With the modular pressure relief assembly adopted, the problem that various pressure release valves or fluid connectors with automatic pressure release functions are complex in structure and large in size are effectively solved.

Description

technical field [0001] The invention relates to the technical field of sealing and pressure relief in a liquid cooling system, in particular to a modular pressure relief assembly capable of automatic pressure relief. Background technique [0002] As is known, during the operation or debugging of the liquid cooling system, it is often necessary to maintain the liquid cooling equipment in the system. After the shutdown, the pressure in the liquid cooling equipment may not be completely relieved. As the ambient temperature rises, the liquid inside the equipment expands due to heat, and the pressure increases sharply, which is enough to overpressure and damage the liquid cooling equipment; when the liquid cooling system operates at the rated pressure, the system may experience unstable supply pressure. At the safe pressure, if the liquid cooling system is always in a closed state, the sudden pressure will cause overpressure damage to the system; in the above two application envi...

Problems solved by technology

[0002] As is known, during the operation or debugging of the liquid cooling system, it is often necessary to maintain the liquid cooling equipment in the system. After the shutdown, the pressure in the liquid cooling equipment may not be completely relieved. As the ambient temperature rises, the liquid inside the equipment expands due to heat, and the pressure increases sharply, which is enough to overpressure and damage the liquid cooling equipment; when the liquid cooling system operates at the rated pressure, the system may experience unstable supply pressure. At the safe pressure, if the liquid cooling system is always in a closed state, the sudden pressure will cause overpressure damage to the system; in the above two application environments, the internal pressure of the liquid cooling equipment rises sharply, because the liquid cooling system is always in a closed state, As a result, the pressure cannot be discharged in time, and the overpressure will cause the failure of the liquid cooling equipment or the entire liquid cooling system; at present, the liquid cooling system mostly uses a pressure relief valve or a fluid connector with automatic pressure relief to solve the harm caused by the system overpressure. However, various pressure relief valves or fluid connectors with automatic pressure relief have complex structures and large volumes, especially when the pressure relief pressure values ​​are different, the structure, volume, and shape are not the same; in addition, due to the miniaturization of the liquid cooling system, Lightweight requirements, under the premise of ensuring functional performance, the smaller the pressure relief component, the better the structure
