Problems solved by technology

Although the above-mentioned radially floating fluid connector solves the problem that it is difficult for the socket and plug without radial floating fluid connector to be inserted smoothly, it is necessary to add some additional structures to ensure accurate positioning.
However, there are problems in that: the internal small O-ring is directly exposed to the fluid with a large flow rate during plugging or working, so it is easy to be damaged or its life is reduced, and it cannot withstand very high flow impacts, nor can it be worn under working conditions. Press plug
At the same time, the structure is complex, the sealing rings and parts used are many, the volume is large, the cost is high, and the friction force required for radial floating is relatively large.

Embodiment 1

[0038] The floating fluid connector prevents the O-ring from being exposed to the fluid with a large flow rate. The specific implementation methods are as follows:

[0039] combine figure 1 (a)~(b), the plug consists of the first housing 1, the first valve core 2, the flange 3, the bushing 4, the pipe joint 5, the first spring 6, the first sealing ring 7, the second sealing ring 8. The third sealing ring 9 is formed. The flange plate 3 and the pipe joint 4 are connected together by screws and sealant 10. The first valve core 2 moves left and right along the axis inside the first housing 1 under the action of the socket or the first spring 6 . The bushing 4 is installed between the first housing 1 and the pipe joint 5 . The second sealing ring 8 installed on the pipe joint 5 acts as a seal when the plug moves radially. When the waterway of the plug is disconnected, when the first valve core 2 moves to the limit position of the first housing 1 under the action of the first s...

Embodiment 2

[0043] The specific implementation of the radial floating of the floating fluid connector is as follows:

[0044] combine Figure 1-3 , increase the size range of the alignment position of the fluid connector plug and socket mainly in the plug structure scheme, the floating fluid connector plug and socket connection and working process, the first housing 1 in the plug can drive the first valve of its internal components Core 2, bushing 4, first spring 6, and second sealing ring 8 move together until they touch the inner wall of flange 3 (see image 3 ), the gap between the inner walls of the first shell 1 and the flange 3 is larger than that of the fluid connector without radial floating, and the radial floating size is larger, so the maximum allowable offset of the axis of the plug and socket is also larger.

[0045] The present invention solves the problem that the current non-radial floating fluid connector socket and plug are floating, and due to the large radial installa...

Abstract

The invention discloses a floating fluid connector which comprises a socket and a plug. According to the structure of the plug, a flange plate and a pipe connector are connected into a whole through ascrew and sealant, a valve element moves along the center axis line inside a shell under the effect of the socket or a spring, a lining is installed between the first shell and the pipe connector, and a sealing ring installed on the pipe connector achieves a sealing effect when the plug moves in the radial direction; when a water way of the plug is in a disconnected state, the valve element movesto a limiting position of the shell under the effect of the spring, the valve element makes contact with a retaining shoulder on the shell to be prevented from moving, and a plug sealed or disconnected state is formed under the effect of the sealing ring; and in the plug and socket connection and work process, the shell in the plug drives internal assemblies to move together till making contact with the inner wall of the flange plate, and the plug and socket floating connection function is achieved. According to the floating fluid connector, radial floating is added, the dual leakage-proof sealing function is achieved, quite high flow impact can be resisted, and equipment reliability is improved.

Description

technical field [0001] The invention relates to the technical field of fluid connectors, in particular to a floating fluid connector. Background technique [0002] As a connection and transmission device between liquid cooling systems, the floating fluid connector generally consists of two parts: a socket installed on the cooling module and a plug installed on the rack or chassis base. The socket and plug need to achieve a good sealing effect in both disconnected and connected states to ensure the normal operation of the liquid cooling system. Floating fluid connectors not only have high requirements for the environmental adaptability of the fluid connector sealing material and the durable fatigue strength of the spring, but also have very high requirements for the sealing principle of the fluid connector, the structural design of the parts, the machining accuracy and the installation. If there is a problem with one of the above, the liquid cooling system will not work prop...
