Abstract
Description
Technical Field
[0001] This application relates to the field of pipeline fitting technology, and in particular to a quick-connect sealing joint device. Background Technology
[0002] Quick-connect sealing joints, also known as fluid connectors, are widely used in industrial and civilian applications as devices that enable rapid connection or disconnection of pipelines. Their core functions lie in reliable sealing during the plug-in state and independent sealing during the disconnected state. Currently, mainstream quick-connect sealing joints employ a male-female plug-in structure and achieve unidirectional sealing through a built-in spring valve core.
[0003] In related technologies, quick-connect sealing connectors consist of a male plug and a female plug. When the male and female plugs are not connected, they achieve independent sealing through their internal spring valve core structures. When the male and female plugs are connected, the valve core moves due to axial thrust, overcoming the spring preload and opening the valve, thus connecting the two pipelines. This design ensures both quick assembly and disassembly while meeting the requirement of independent sealing. However, leakage is prone to occur during the insertion and removal of the male and female plugs, i.e., when the valve core moves. Utility Model Content

[0039] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0040] like Figures 1 to 4 As shown in the figure, this application provides a quick-connect sealing joint device, including a male connector 1 and a female connector 2.
[0041] The male connector 1 includes a first housing 11, which has a first fluid channel 12 extending through it. A first valve core 13 and a first spring 14 are disposed within the first fluid channel 12. A first sealing ring 15 is provided on the inner wall of one end of the first housing 11. The first valve core 13 is slidably connected to the first housing 11 and can slide up and down within it. The first spring 14 can drive the first valve core 13 to pass through the first sealing ring 15. When the male connector 1 and the female connector 2 are not inserted, such as... Figure 2As shown, the first spring 14 drives the first valve core 13 to move downward to the lower end of the first housing 11, and the first sealing ring 15 located at the lower end of the first housing 11 is sleeved on the first valve core 13, thereby sealing the lower end of the first fluid channel 12.
[0042] The female connector 2 includes a second housing 21, which has a second fluid channel 22 extending through it. A second valve core 23, a second spring 24, and a valve body 25 are disposed within the second fluid channel 22. A second sealing ring 26 is provided on the inner wall of one end of the second housing 21. The valve body 25 is slidably connected to the second housing 21 and can slide up and down within it. The second spring 24 can drive the valve body 25 to pass through the second sealing ring 26. The second valve core 23 is fixedly connected to the second housing 21, and the valve body 25 is fitted onto it. A third sealing ring 27 is provided on the inner wall of the valve body 25 to seal the ends of the valve body 25 and the second valve core 23. Figure 2 As shown, the second spring 24 drives the valve body 25 to move upward to the upper part of the second housing 21. The second sealing ring 26 located at the upper end of the second housing 21 is sleeved on the valve body 25 and seals the valve body 25 with the second housing 21. The third sealing ring 27 inside the valve body 25 is sleeved on the second valve core 23 and seals the valve body 25 with the second valve core 23. Thus, the second sealing ring 26 and the third sealing ring 27 seal the upper end of the second fluid channel 22.
[0043] like Figure 3 and Figure 4 As shown, when the male connector 1 and the female connector 2 are plugged in, the lower end of the first housing 11 presses down against the valve body 25, the end of the first housing 11 is inserted into the second housing 21, and at the same time the second valve core 23 presses against the first valve core 13, causing the first valve core 13 to slide upward relative to the first housing 11. The second valve core 23 is inserted into the first housing 11, the first sealing ring 15 is sleeved on the second valve core 23, and the second sealing ring 26 is sleeved on the first housing 11, thereby connecting the first fluid channel 12 and the second fluid channel 22.
[0044] Figure 2 and Figure 4 The dashed lines in the diagram represent the flow path of the liquid. Figure 2 In the first fluid channel 1, the liquid in the male connector 1 flows downward from the upper end of the first housing 11 into the first fluid channel 12, and is sealed at the lower end of the first fluid channel 12 to prevent leakage. The liquid in the female connector 2 flows upward from the lower end of the second housing 21 into the second fluid channel 22, and is sealed at the upper end of the second fluid channel 22 to prevent leakage. Figure 4 In the process, the first fluid channel 12 and the second fluid channel 22 are connected, and liquid can flow from the male connector 1 into the female connector 2, or from the female connector 2 into the male connector 1.
[0045] Based on the above scheme, a first sealing ring 15 is provided on the inner wall of one end of the first housing 11, a second sealing ring 26 is provided on the inner wall of one end of the second housing 21, and a third sealing ring 27 is provided on the inner wall of the valve body 25. When not inserted, the first spring 14 drives the first valve core 13 to pass through the first sealing ring 15, and the first sealing ring 15 seals the first valve core 13 and the first housing 11, thereby sealing the first fluid channel 12. The second spring 24 drives the valve body 25 to pass through the second sealing ring 26, and the second sealing ring 26 seals the valve body 25 and the second housing 21. At the same time, the third sealing ring 27 seals the ends of the valve body 25 and the second valve core 23, thereby sealing the first fluid channel 12. The two fluid channels 22 are sealed. During insertion and removal, the end of the first housing 11 is inserted into or pulled out of the second housing 21. The second sealing ring 26 seals the moving first housing 11 and the second housing 21 to prevent leakage. At the same time, the second valve core 23 is inserted into or pulled out of the first housing 11. The first sealing ring 15 seals the moving first housing 11 and the second valve core 23, also preventing leakage. Until it is fully inserted, the first sealing ring 15 and the third sealing ring 27 are no longer sealed with the second valve core 23, and the first fluid channel 12 and the second fluid channel 22 are connected. Alternatively, until it is fully removed, the first fluid channel 12 and the second fluid channel 22 return to an independent sealing state. Therefore, the quick-connect sealing joint device described above can improve the sealing performance during insertion and removal.
[0046] In some embodiments, such as Figure 2 , Figure 4 , Figures 8 to 10 As shown, the diameter of the middle part of the second valve core 23 is smaller than the diameter of the end of the second valve core 23. Specifically, the diameter of the middle part of the second valve core 23 is smaller than the diameter of its upper end, so that when the valve body 25 is located at the upper end of the second valve core 23, the third sealing ring 27 seals the upper end of the second valve core 23 and the valve body 25. Similarly, when the first sealing ring 15 is located at the upper end of the second valve core 23, it seals the upper end of the second valve core 23 and the first housing 11. Figure 4 As shown, when the third sealing ring 27 and the first sealing ring 15 are located in the middle of the second valve core 23 with a smaller diameter, the third sealing ring 27 and the first sealing ring 15 are not sealed with the second valve core 23, and the liquid can flow between the second valve core 23 and the valve body 25, and between the second valve core 23 and the first housing 11, thereby connecting the first fluid channel 12 and the second fluid channel 22.
[0047] In some embodiments, such as Figures 1 to 4As shown, the first housing 11 includes a connected insertion section 111 and a housing body section 112, with the outer diameter of the insertion section 111 being smaller than the outer diameter of the housing body section 112. Specifically, the insertion section 111 is located at the lower end of the housing body section 112, and the insertion section 111 is inserted downward into the second housing 21 until the housing body section 112 abuts against the upper surface of the second housing 21 to be fully inserted.
[0048] In some embodiments, the diameter of the end of the first valve core 13 is the same as the diameter of the end of the second valve core 23, and the outer diameter of the insertion section 111 is the same as the outer diameter of the valve body 25. Thus, during insertion, after the end of the second valve core 23 extends into the first housing 11, the first sealing ring 15 can seal the end of the second valve core 23 with the first housing 11, and after the insertion section 111 extends into the second housing 21, the second sealing ring 26 can seal the insertion section 111 with the second housing 21.
[0049] In some embodiments, such as Figures 1 to 7 As shown, the first housing 11 has a first connector 16 at the end away from the first sealing ring 15, and a first flange 131 at one end of the first valve core 13. The first spring 14 is a compression spring, which abuts against the first flange 131 and the first connector 16. When the first valve core 13 moves upward, it compresses the first spring 14. The first flange 131 may have multiple circumferential openings to allow liquid to pass through.
[0050] In some embodiments, a fourth sealing ring 17 is provided between the first housing 11 and the first connector 16. The fourth sealing ring 17 seals the space between the first housing 11 and the first connector 16.
[0051] In some embodiments, such as Figure 2 , Figure 4 , Figures 8 to 10 As shown, the second valve core 23 has a second flange portion 231 at the end away from the second sealing ring 26, and the second spring 24 is a compression spring, which abuts against the second flange portion 231 and the valve body 25. The second flange portion 231 may have multiple openings circumferentially provided to allow liquid to pass through.
[0052] In some embodiments, such as Figures 1 to 4 As shown, a second connector 28 is provided at the end of the second housing 21 away from the second sealing ring 26, and a fifth sealing ring 29 is provided between the second housing 21 and the second connector 28. The fifth sealing ring 29 seals the space between the second housing 21 and the second connector 28.
[0053] The first connector 16 and the second connector 28 can be pipe fittings or individual parts, or they can be part of an external part.
[0054] In some embodiments, such as Figure 11 and Figure 12As shown, a first fixing member 18 is fitted around the outer periphery of the first housing 11, and a second fixing member 230 is fitted around the outer periphery of the second housing 21. The first fixing member 18 and the second fixing member 230 can be connected to the external components while assembling and fixing the male connector 1 and the female connector 2. The first fixing member 18 and the second fixing member 230 can be separate parts or part of the external components.
[0055] In some embodiments, the first sealing ring 15, the second sealing ring 26, and the third sealing ring 27 are O-rings or Y-rings. Similarly, the fourth sealing ring 17 and the fifth sealing ring 29 are also O-rings or Y-rings.
[0056] The working principle of the quick-connect sealing joint device provided in this application embodiment is as follows:
[0057] When the connectors are in the open state, in the absence of any other external force, the first spring 14 lifts the first valve core 13 to the limit position of the first housing 11, and the liquid flows from the first connector 16 through the internal parts of the male connector 1 and is finally sealed by the first sealing ring 15.
[0058] When the connector is in the open state, the female connector 2: In the absence of other external forces, the second spring 24 pushes the valve body 25 to the upper position of the second housing 21, and the liquid flows from the second connector 28 through the internal parts of the female connector 2, and finally to the second sealing ring 26 and the third sealing ring 27 to be sealed.
[0059] Connector connection state: Under the influence of external forces or gravity, the first housing 11 presses down on the valve body 25, the second valve core 23 presses up on the first valve core 13, and at the same time, the first spring 14 and the second spring 24 are compressed; the liquid flows out from the first connector 16 after passing through the inside of the female connector 2 and the inside of the male connector 1 from the second connector 28.
[0060] When the connector is disconnected by an external force, it returns to the disconnected state. As described above, the valve core automatically closes to prevent leakage.
[0061] Existing connectors typically have an outer sleeve on the outside of the housing. Before connecting or disconnecting, the sleeve must be manually pressed or removed. This adds an extra step to each operation, wasting time, and is unusable in specific situations such as concealed locations, inconvenient manual operation, or inside equipment. The quick-connect sealing connector device provided in this application eliminates the need for an outer sleeve, allowing for quick connection and disconnection followed by automatic sealing. It can be applied to quick-connect sealing connectors in concealed locations, inconvenient manual operation, or inside equipment, filling the gap in available sealing connectors in certain scenarios. It also simplifies the connection and disconnection process, increasing work efficiency.

Furthermore, it is understood that the steps in the method of this application embodiment can be adjusted, combined, and deleted according to actual needs, and the modules in the device of this application embodiment can be combined, divided, and deleted according to actual needs.
