DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0039] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] The following describes a quick-insertion structure of a valve according to an embodiment of the present application with reference to the accompanying drawings.

[0042] See also Figures 1-11 According to an embodiment of the present application, a quick-insertion structure of a valve includes: a valve body 1, a male docking part 2 and a female docking part 3.

[0043] The valve body 1 is molded with male and female fittings 2 and 3. These pre-installed male and female fittings 2 and 3 quickly connect to the pre-installed female and male fittings 3 and 2 on the test equipment pipeline. Compared to traditional threaded connections or flange mounting methods, this valve's quick-install design allows for faster and more convenient testing. When this valve's quick-install design connects to system piping, the corresponding male and female fittings 2 and 3 are also installed and used on the system piping ports.

[0044] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 6The male docking part 2 includes an outer protective shell 21, an outer tube 22 and an inner tube 23. One end of the outer protective shell 21 can be connected to the liquid inlet port of the valve body 1 by welding. The inner tube 23 is elastically inserted into the outer tube 22 through the cooperation of the second spring 25. The outer tube 22 is elastically inserted into the outer protective shell 21 through the cooperation of the first spring 24. The outer side of the outer tube 22 is respectively provided with a limiting hole 221 and a water outlet hole 222, and a ball 27 is provided at the tail end of the outer protective shell 21. A driving structure is provided on the outside of the outer protective shell 21 to drive the inner tube 23 to move axially. The female docking part 3 includes a front shell 31 and a rear shell 32 that are connected. One end of the rear shell 32 is connected to the liquid outlet port of the valve body 1, and a movable elastic sealing part is provided inside the front shell 31. The inner walls of the front shell 31 and the rear shell 32 are respectively provided with interconnected guide holes 311 and guide cavities 321, and the inner wall of the front shell 31 is provided with an annular groove 39 that cooperates with the ball 27.

[0045] During pre-test docking and installation, the male docking member 2 at one end of the valve body 1 is docked with the female docking member 3 at the end of the test equipment pipeline, and the female docking member 3 on the valve body 1 is docked with the male docking member 2 at the end of the test equipment pipeline. Specifically, the docking and installation method is as follows: the driving structure pushes the inner tube 23 inside the outer protective shell 21 toward one end of the outer tube 22. At this time, the moving inner tube 23 pushes the second spring 25 and the outer tube 22 toward the interior of the front shell 31. The moving end of the outer tube 22 squeezes the elastic sealing portion inside the front shell 31, ultimately allowing the end of the outer protective shell 21 to be inserted into the interior of the front shell 31, and the end of the outer tube 22 continues to be inserted deeper into the interior of the front shell 31. Until the limiting hole 221 on the outside of the outer tube 22 moves to the inside of the annular groove 39, the ball 27, which continues to be squeezed by the movement of the inner tube 23, protrudes outward from the limiting hole 221 and snaps into the inside of the annular groove 39, and the driving mechanism stops driving, completing the plug-in fixation of the female docking part 3 and the male docking part 2. At this time, the liquid enters the diversion cavity 321 through the opening at the end of the front shell 31, and the liquid inside the diversion cavity 321 enters the groove on one side through the diversion hole 311 inside the front shell 31. At this time, the water outlet 222 on the outside of the outer tube 22 is at the radial inner position of the groove. The liquid flowing from the diversion hole 311 into the groove directly enters the outer tube 22 and the inner tube 23 through the water outlet 222, and then enters the inner shell 21 along the inner tube 23, completing the liquid circulation.

[0046] When the female docking part 3 and the male docking part 2 are disassembled, the axial pressure applied to the inner tube 23 by the driving structure is removed, and the outer tube 22 is driven to move along the axial position away from the end of the front shell 31 under the expansion elastic force of the second spring 25 and the first spring 24. While the outer tube 22 is resetting, the elastic sealing part resets and blocks the front shell 31 under the elastic power. The ball 27 at the end of the outer tube 22 moves inward along the radial position to disengage from the snap fit with the annular groove 39. At this time, the end of the outer protective shell 21 can be pulled out from the end of the front shell 31, completing the rapid disassembly of the male docking part 2 and the female docking part 3. The quick plug-in structure of the valve replaces the traditional threaded connection or flange connection installation method. When used with test equipment for detection and testing, it has a faster disassembly and assembly speed, which can greatly improve the overall detection and testing efficiency of the valve.

[0047] In the above specific implementation, please refer to Figure 6 The elastic sealing portion includes a sealing block 33, a support rod 34, a retaining ring 35, and a third spring 36. The sealing block 33 is slidably mounted within the front housing 31. One end of the support rod 34 is connected to the sealing block 33, and the retaining ring 35 is fixedly mounted on the outside of the support rod 34. The third spring 36 supports the inner end wall of the front housing 31 and the retaining ring 35. The sealing block 33, support rod 34, and retaining ring 35 can be integrally formed.

[0048] When the outer tube 22 inside the outer protective shell 21 moves and the end of the outer tube 22 squeezes the blocking block 33, the moving blocking block 33 simultaneously squeezes the third spring 36 through the support rod 34 and the retaining ring 35 until the ball 27 is locked into the annular groove 39. When the female docking member 3 and the male docking member 2 are disassembled, the blocking block 33 moves and resets under the elastic force of the third spring 36 through the retaining ring 35 and the support rod 34, thereby pushing the outer tube 22 out of the front shell 31.

[0049] Furthermore, an integrally formed limiting column 38 is provided at the bottom end of the front shell 31 , and one end of the third spring 36 is sleeved on the outside of the limiting column 38 . The setting of the limiting column 38 is to improve the stability of the third spring 36 when it is compressed and relaxed.

[0050] Specifically, the female docking member 3 further includes sealing rings 37, and two sets of sealing rings 37 are disposed inside the front shell 31. The provision of the sealing rings 37 is to improve the sealing between the blocking block 33 and the front shell 31, and to improve the sealing between the end of the outer tube 22 and the front shell 31 after being inserted into the front shell 31.

[0051] For specific settings, see Figure 4A support tube 29 is provided at one end of the inner tube 23, and a support surface 231 for supporting the ball 27 is provided between the inner tube 23 and the support tube 29. The male connector 2 also includes a flange 28, which is fixed to the other end of the inner tube 23. The moving inner tube 23 moves together with the support tube 29. When the outer tube 22 is inside the outer protective shell 21, the ball 27 contacts the outer surface of the support tube 29. When the inner tube 23 gradually moves to push the end of the outer tube 22 into the front shell 31 and contact the blocking block 33, the inner tube 23 also gradually moves, and at the same time, the flange 28 compresses the second spring 25, and the moving inner tube 23 pushes the support surface 231 to move and contact the ball 27. The ball 27 inside the limiting hole 221 gradually protrudes outward and is stuck in the annular groove 39. During disassembly, the flange 28 and the inner tube 23 move in opposite directions, and the ball 27 gradually moves from the supporting surface 231 to the outer surface of the supporting tube 29 , and the ball 27 is disengaged from the engagement state with the annular groove 39 .

[0052] Furthermore, an end sleeve 26 is provided at one end of the outer tube 22, and the second spring 25 is provided between the inner end surface of the end sleeve 26 and the flange 28. The end sleeve 26 is used to limit one end of the second spring 25.

[0053] Specifically, at least two O-rings are provided between the outer tube 22 and the outer shell 21. The O-rings are provided to improve the sealing between the outer tube 22 and the outer shell 21. The balls 27 and the limiting holes 221 are distributed in multiple groups of annular arrays on the outside of the outer tube 22.

[0054] In the specific configuration, the front shell 31 is provided with a plug-in slot that matches the end of the outer shell 21 at one end away from the rear shell 32. That is, the end of the outer shell 21 is inserted into the interior of the front shell 31 more smoothly.

[0055] How the driving structure in the quick-insertion structure of the valve can more accurately drive the outer tube 22 to move inside the outer protective shell 21 is a problem that needs to be solved.

[0056] In the above specific implementation, please refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 7The drive structure includes a drive connector 4 and a hydraulic drive component 5. The drive connector 4 includes a connecting block 41, a pressure rod 42, a connecting rod 43, and a bent rod 44. The inner wall of the outer protective shell 21 is respectively provided with a guide groove 212 and an avoidance groove 211 that are connected to each other. The connecting block 41 is fixed to the outside of the flange 28. One end of the pressure rod 42 is connected to the connecting block 41, and the other end of the pressure rod 42 is connected to the connecting rod 43 through the bent rod 44. A piston head 45 is provided at the end of the connecting rod 43 away from the bent rod 44. The pressure rod 42 is movably inserted into the guide groove 212. The end of the guide groove 212 away from the avoidance groove 211 is provided with a mounting groove 214. The hydraulic drive component 5 includes a hydraulic actuator 51 and a hydraulic release blocking portion 52. The hydraulic release blocking portion 52 is provided at the top of the mounting groove 214. The hydraulic actuator 51 is provided on the outside of the outer protective shell 21 and cooperates with the hydraulic release blocking portion 52 to adjust the fluid pressure inside the guide groove 212.

[0057] By pressing the hydraulic actuator 51 in the hydraulic drive element 5, the pre-installed liquid inside the hydraulic actuator 51 enters the guide groove 212 through the hydraulic release sealing portion 52, squeezing the piston head 45. The liquid squeezes the piston head 45, driving the connecting rod 43 to move, which in turn drives the connecting block 41 and the flange 28 through the bent rod 44 and the pressure rod 42, ultimately driving the inner tube 23 to move axially within the outer tube 22. The moving inner tube 23 drives the outer tube 22 outside via the external balls 27 until the end of the outer tube 22 is inserted into the front shell 31. After the balls 27 in the limiting holes 221 protrude outward and engage the annular groove 39, pressure on the hydraulic actuator 51 is stopped to discharge the liquid. At the same time, the hydraulic release sealing portion 52 prevents the liquid in the guide groove 212 from flowing back.

[0058] When the male and female docking parts 2 and 3 need to be disassembled, the guide groove 212 is connected to the hydraulic actuator 51 through the hydraulic release sealing part 52. Under the elastic force of the second spring 25 and the first spring 24, the inner tube 23 is driven to reset and move. The moving inner tube 23 drives the connecting block 41 to move through the flange 28, that is, the piston head 45 is driven to move through the pressure rod 42, the bent rod 44 and the connecting rod 43 to squeeze the liquid inside the guide groove 212 back to the hydraulic actuator 51 through the hydraulic release sealing part 52, so as to achieve accurate and rapid control of the male and female docking parts 2 and 3 to complete the disassembly and assembly operations.

[0059] When the connecting rod 43 moves in the guide groove 212 , the bent rod 44 also moves smoothly in the avoidance groove 211 .

[0060] How the quick-insertion structure of the valve can achieve control and stopping of the liquid pressure through the specific structure of the hydraulic actuator 51 and the hydraulic release blocking part 52 is a problem to be solved.

[0061] For further information, see Figure 8 、 Figure 9 and Figure 10 The hydraulic actuator 51 includes a flexible sleeve 511, a positioning shell 512, a support ring 513, and a spiral flexible pad 514. The support ring 513 is connected to the positioning shell 512, and the positioning shell 512 and the support ring 513 are both fixed to the outside of the outer protective shell 21. The flexible sleeve 511 is arranged outside the support ring 513 and communicates with the positioning shell 512. The spiral flexible pad 514 is arranged in a cavity within the flexible sleeve 511. The spiral flexible pad 514 is provided with a cavity layer 515 inside. The side edge of the spiral flexible pad 514 near the outer wall of the flexible sleeve 511 is provided with an inclined surface 516. The hydraulic release blocking part 52 includes a vertical pipe 521, a protective shell 522, a button 523, a vertical rod 524, a support block 525, a fourth spring 526, a vertical rod 527 and a blocking head 528. The bottom end of the vertical pipe 521 is connected and arranged inside the mounting groove 214. A flow port 529 is arranged inside the vertical pipe 521. The fourth spring 526 is arranged above the flow port 529. The blocking head 528 is located below the flow port 529. The support block 525 is located above the fourth spring 526. The vertical rod 524 connects the button 523 and the support block 525. The protective shell 522 is fixed to the outside of the positioning shell 512. The vertical rod 527 connects the support block 525 and the blocking head 528. A guide port 5211 is provided on the outside of the vertical pipe 521 above the flow port 529.

[0062] The flexible sleeve 511 in the hydraulic actuator 51 is squeezed, and the liquid inside the flexible sleeve 511 flows along the cavity between the spiral flexible pad 514 and the flexible sleeve 511 into the connected positioning housing 512. The liquid inside the positioning housing 512 then flows through the guide port 5211 on the outside of the standpipe 521 into the standpipe 521 above the flow port 529. The liquid inside the standpipe 521 above the flow port 529 is pressurized downward, forcing the plugging head 528 below to gradually move downward, creating a gap between the plugging head 528 and the inner wall of the flow port 529. The liquid in the upper layer of the flow port 529 can now flow through the gap between the flow port 529 and the plugging head 528 into the guide groove 212, forcing the piston head 45 and the connecting rod 43 to move within the guide groove 212. Simultaneously, the downward movement of the plugging head 528, via the standpipe 527, simultaneously drives the support block 525 downward, compressing the fourth spring 526.

[0063] When the male and female connectors 2 and 3 need to be disassembled, the button 523 inside the protective shell 522 is pressed downward. The protective shell 522 serves to protect against accidental touching. The downwardly moving button 523 drives the support block 525 downward via the vertical rod 524, thereby driving the vertical rod 527 and the plugging head 528 downward. At this time, a gap is created between the plugging head 528 and the flow port 529. The liquid inside the guide groove 212 is pushed back into the flexible sleeve 511 due to the reduced reset thrust of the piston head 45 and the connecting rod 43.

[0064] The spiral flexible pad 514 inside the flexible sleeve 511 adopts a spiral structure, which not only facilitates the flow of liquid in the internal cavity of the flexible sleeve 511, but also enables the flexible sleeve 511 to have a good relaxation and reset function. That is, when the button 523 is pressed down, the liquid inside the guide groove 212 is also more easily sucked into the flexible sleeve 511. The design of the cavity layer 515 inside the spiral flexible pad 514 is to enhance the overall relaxation ability of the spiral flexible pad 514, that is, to enhance the relaxation and reset ability of the flexible sleeve 511. The two sides of the top of the spiral flexible pad 514 are designed with inclined surfaces 516 to reduce the resistance when pressing the flexible sleeve 511, that is, it is easier to compress the flexible sleeve 511 and the spiral flexible pad 514, and the flexible sleeve 511 and the spiral flexible pad 514 also have better relaxation and reset capabilities.

[0065] The flexible sleeve 511 and the spiral flexible pad 514 may be made of a flexible material with good elasticity, such as a rubber material or a latex material.

[0066] If the sealing head 528 in the quick-insertion structure of the valve can have a better sealing effect with the flow port 529, the stability of the male docking member 2 and the female docking member 3 after docking can be further improved.

[0067] For details, please refer to Figure 11 The plugging head 528 comprises a hemispherical hard block 5281, a sealing sleeve 5282, and a truncated cone-shaped sealing gasket 5283. The bottom end of the vertical rod 527 is connected to the hard block 5281. The sealing sleeve 5282 is mounted on the outside of the hard block 5281. The sealing gasket 5283 is integrally formed at the bottom of the sealing sleeve 5282 and has a groove 5284 at the bottom.

[0068] When liquid enters the riser 521 through the guide port 5211, it pushes the hard block 5281, the sealing sleeve 5282, and the sealing gasket 5283 downward through the flow port 529. This creates a gap between the flow port 529 and the hard block 5281, allowing the liquid to flow into the guide groove 212. When the male and female fittings 2 and 3 are stably connected, the liquid inside the guide groove 212 reaches a relatively high pressure. At this point, the outer wall of the sealing sleeve 5282 contacts the flow port 529, providing a good seal. Simultaneously, the liquid enters the groove 5284, pressing the inner wall of the sealing gasket 5283 outward, causing the outer wall of the sealing gasket 5283 to fit tightly against the inner wall of the riser 521. This means that after the male and female fittings 2 and 3 are secured, the sealing head 528 effectively locks the liquid in and prevents backflow, ensuring a durable and stable connection between the male and female fittings 2 and 3.
