Description

Technical Field

[0001] The utility model relates to a liquid flow joint structure, in particular to a liquid flow joint structure capable of increasing the flow rate and pressure of a fluid. Background Art

[0002] In the current gas supply system or liquid cooling system, pipes and joints 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 the safety and stability of the system. 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 head of the quick connector is connected to the fixed module, and one end of the male head is connected to the hose and the other end is connected to the female head plug end for connection, thereby realizing the conduction or disconnection of the pipeline in the system.

[0003] See also Figure 4A The existing male and female connection structure includes the male end connecting 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 extends from the outer end 121 of the valve body with a valve body extension 122 and is slidably accommodated in the internal groove of the central component 15. The central component 15 is fitted to the male end valve body 12 and is retained in the interior of the male end body 11. Through the male end valve body spring 13, the male end valve body 12 and the central component 15, when the female end connecting element 20 is disconnected, the male end valve body 12 cooperates with the male end body 11 and makes the male end 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 push rod 25. The female end push rod 25 is accommodated inside the female end main body 21 and fixed to the female end main body 21 by the locking nut 24. The female end valve body 22 is fitted to the female end push rod 25 and connected to the female end main body 21, so that in the disconnected state where the male end connecting element 10 is not connected, the female end valve body 22 tightly matches the female end push rod 25 and the female end main body 21. When the male and female end connecting elements 10 and 20 are connected, the male end main body 11 corresponds to and enters the interior of the female end main body 21, so that the female end push 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 main body 11 and the female end valve body 22 moves axially inside the female end main body 21, so as to achieve fluid communication. However, the above-mentioned conventional joint assembly has the following problems.

[0004] Please refer to Figure 4B , Figure 4C For learning Figure 4ASchematic diagram of aa section and bb section; because the male end body 11 is guided and moved by the female end body 21, when the female end push rod 25 moves forward and contacts the male end valve body 12 and pushes it back, the cross-sectional area A (such as Figure 4B As shown), the cross-sectional area B (as shown) formed by the central shaft 251 of the female end push rod 25 and the opening 11a of the free end of the male end body 11 Figure 4C As shown), and the cross-sectional area A is smaller than the cross-sectional area B, but due to the limited size of the cross-sectional area A, the flow rate of water available for flow becomes smaller, 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, the male end body 11 may be bent and broken, or the male and female end bodies 11, 21 may be separated, resulting in water leakage and other problems. Therefore, the above-mentioned conventional defects are the primary problems to be solved in this case. Utility Model Content
