Description

Fluid flow joint structure

A fluid joint structure, especially a fluid joint structure that increases fluid flow rate and pressure.

According to the current gas supply system or liquid cooling system, pipes and connectors are usually used to connect the modules. There is flowing gas or liquid inside the pipes. The individual module units need to be disconnected and connected frequently during use and maintenance. However, when the pipe disconnection operation is cumbersome, leakage is prone to occur, affecting the environment and system safety and stability. Therefore, it is necessary to use a quick disconnect connector (Quick Disconnect Coupler) with a quick disconnect and one-way sealing function, commonly known as a QDC quick connector. Usually, the female end of the quick connector is connected to the fixed module, and one end of the male end is connected to the hose and the other end is connected to the female end for connection, thereby realizing the connection or disconnection of the pipeline in the system.

Referring to FIG. 4A , the existing male and female connection structure includes the male end connection element 10 which is plugged into each other and has a male end body 11, a male end valve body 12, a male end valve body spring 13, a fixing ring 14 and a central component 15. The male end valve body 12 is accommodated in the interior of the male end body 11, and the valve body extension portion 122 extends from the valve body outer end 121 and is slidably accommodated in the central component 15. In the inner groove of the central component 15, the central component 15 is mounted on the male end valve body 12 and is retained inside the male end main body 11. Through the male end valve body spring 13, the male end valve body 12 and the central component 15, in the disconnected state where the female end connecting element 20 is not connected, the male end valve body 12 cooperates with the male end main body 11 and makes the male end main body 11 move axially relative to the fixing ring 14. The female end connecting element 20 comprises a female end main body 21, a female end valve body 22, a female end valve body spring 23, a locking nut 24 and a female end top rod 25. The female end top rod 25 is accommodated inside the female end main body 21 and fixed to the female end main body 21 through the locking nut 24. The female end valve body 22 is fitted onto the female end top rod 25 and connected to the female end main body 21, so that in a disconnected state where the male end connecting element 10 is not connected, the female end valve body 22 closely matches the female end top rod 25 and the female end main body 21. When the male and female connecting elements 10 and 20 are connected, the male end body 11 corresponds to and enters the interior of the female end body 21, so that the female end top rod 25 contacts and presses against the male end valve body 12, so that the male end valve body 12 moves axially inside the male end body 11 and the female end valve body 22 moves axially inside the female end body 21, so as to achieve fluid connection. However, the above known joint assembly has the following problems.

Please refer to Figures 4B and 4C for the a-a and b-b cross-sectional schematic diagrams of Figure 4A. Since the male body 11 is guided and moved by the female body 21, when the female push rod 25 moves forward and contacts the male valve body 12 to push it back, the cross-sectional area A (as shown in Figure 4B) formed between the inner wall surfaces of the male valve body 12 and the male body 11 is smaller than the cross-sectional area B (as shown in Figure 4C) formed between the central rod 251 of the female push rod 25 and the opening 11a of the free end of the male body 11. However, due to the limited size of the cross-sectional area A, the available water flow rate is reduced, which greatly affects the amount of water entering the male end body 11 through the central component 15. Even if the water flow source is increased, it will cause blockage at the cross-sectional area A of the male end body 11 to generate an internal water flow pressure. Over time, when the internal and external pressures of the male end body 11 continue to be different, it may cause the male end body 11 to bend and crack, or the male and female end bodies 11 and 21 may separate from each other, resulting in water leakage and other problems. Therefore, the above-mentioned lack of knowledge is the primary problem to be solved in this case.

Therefore, in order to effectively solve the above problems, the main purpose of this invention is to provide a fluid joint structure. When the first and second joints are connected, the inner wall of the first shell is formed into a gradually expanding arc-shaped inner wall surface to form a similar cross-sectional area with the first and second shaft cores respectively, thereby maintaining a closed state and performing radial displacement, which can increase the smooth water flow and thus improve the overall connection reliability.
