The left valve head 231 is arranged on the left end of the valve head connecting valve rod 233, and the right valve head 232 is arranged on the right end of the valve head connecting valve rod 233. The left valve head 231 is in the shape of a circular truncated cone with a gradually increasing diameter from the right end to the left end, which is used to reduce fluid resistance. The right valve head 232 comprises a plurality of fan-shaped flow guide holes 2321, which are separated by flow guide hole walls 2322. The flow guide hole walls 2322 are provided with flow guide grooves 23221 at the base.

[0039] A right valve head limiting snap spring groove 2114 is formed around the circumference of the female plug housing cavity 211 at a position corresponding to the right side of the right valve head 232, and a snap spring 21141 is embedded in the right valve head limiting snap spring groove 2114, with the edge of the right side surface of the right valve head 232 abutting against the left side surface of the snap spring 21141. A left valve head sealing ring 2311 is embedded on the left valve head 231, which forms a sealing fit with the cavity wall of the sleeve cavity 221 of the sleeve 22 when the male plug housing 11 and the female plug housing 21 are in a non-plugged state of mutual separation, and when the male plug housing 11 and the female plug housing 21 are in a mutual plugged state, the left valve head sealing ring 2311 is located at the right end of the positive hollow plug post cavity 121 together with the left valve head 231, and a gap for fluid passage is maintained between the left valve head sealing ring 2311 and the cavity wall of the positive hollow plug post cavity 121.

[0040] In the present embodiment, the number of the flow guide holes 2321 is three, but can also be four or five, that is, the number of the flow guide holes 331 can be increased or decreased within a reasonable range, which should be considered as an equivalent alternative.

[0041] Referring to Figure 6 The right cavity opening of the sleeve cavity 221 of the sleeve 22 is in the shape of a horn 222 for increasing the flow area and reducing the flow resistance.

[0042] Referring to Figure 7 and in combination with Figures 2-3 Since the male plug mechanism 1 and the female plug mechanism 2 are respectively arranged on the cooling cabinet drawer and the cooling cabinet body of the cooling device structure system of a server or the like, the cooling device drawer adapter 113 of the male plug housing 11 is adapted to the interface on the cooling cabinet drawer, and the female plug housing external thread 215 on the right end outer wall of the female plug housing 21 is adapted to the interface on the cooling cabinet body. When entering the use state, i.e., entering the state of circulating and cooling the cooling liquid in the cooling cabinet, the cooling cabinet drawer is pushed to insert the positive hollow plug post 12 of the structure system of the male plug housing 11 into the female plug housing cavity 211, and during the insertion process, the male plug hollow plug post guide slope 114 and the female plug housing cavity guide slope 212 are guided by each other, so that the insertion and adaptation can be conveniently, quickly and accurately performed. After the insertion and adaptation, the left valve head 231 is located at the right end of the positive hollow plug post cavity 121, and the left valve head sealing ring 2311 is in sealing fit with the cavity wall of the positive hollow plug post cavity 121, and the right valve head 232 is in sealing fit with the right end of the female plug housing cavity 211, so that the cooling liquid in the cooling cabinet can be circulated and cooled. Figure 7As shown, the male plug valve core return spring 15 and the valve sleeve return spring 24 are both in a compressed energy storage state, and the complete flow path is formed. Assuming that the cooling fluid is introduced from the cooling device drawer adapter cavity 1131, it then passes through the left end of the active hollow plug cavity 121, the male plug valve core 14, and the space between the left valve head 231 and the middle of the active hollow plug cavity 121, the space between the valve head connecting valve rod 233 and the right end of the active hollow plug cavity 121, the space between the valve head connecting valve rod 233 and the sleeve cavity 221, and then out of the right end port 2113 of the female plug housing cavity 211 and into the cooling cabinet body to form a circulating backflow (through the corresponding pipeline), as shown in the state of Figure 7 Conversely, the fluid can also flow from the right end port 2113 of the female plug housing cavity 211 and pass through the female plug valve core 23, the sleeve cavity 221 of the sleeve 22, and the active hollow plug cavity 121, and then out of the cooling device drawer adapter cavity 1131 to form a circulating backflow.

[0043] When the plug connection between the male plug housing 11 and the female plug housing 21 is to be released, the separation can be achieved by pulling the cooling cabinet drawer, and due to the restoring force of the male plug valve core return spring 15 and the valve sleeve return spring 24 which were previously in a compressed energy storage state, the male plug mechanism 1 and the female plug mechanism 2 are in the states of Figure 2 and Figure 3 respectively.

[0044] Embodiment 2: Please refer to Figure 8 A male plug valve core return spring support step 1133 protruding from the surface of the male plug housing cavity 111 is formed around the circumference of the male plug housing cavity 111 at the right cavity opening of the male plug housing cavity 111, and the left end of the male plug valve core return spring 15 extends to the right cavity opening of the male plug housing cavity 111 and is supported on the male plug valve core return spring support step 1133.
