The installation process of the invention is as follows, firstly, the first sealing ring 12 is installed in the quick-connect and-go joint 1, the dust-proof ring 13 is installed in the O-shaped ring groove 14 in the quick-connect and-go joint 1, as shown in fig. 2, the protrusion 141 of the O-shaped ring groove 14 is positioned in the rotation-proof groove 131 of the dust-proof ring 13, and the second sealing ring 24 is installed in the nut seat 2. The connecting ring 53 of the locking clamp spring 5 is aligned with the limiting ring 66 and is placed into the clamp spring positioning groove 61, the locking clamp spring 5 is unfolded by clamp spring pliers until the sharp hook 51 of the locking clamp spring 5 hooks the positioning step 67, the clamp spring pliers are loosened, the annular bulge of the positioning clamp ring 52 penetrates through the hollowed-out ring 65 to enter the positioning ring 6, and the installation of the locking clamp spring 5 and the clamp spring positioning groove 61 is completed. The auxiliary locking clamp spring 4 is also installed in the auxiliary clamp spring positioning groove 62 by using clamp spring pliers. Then the convex ring 63 of the positioning ring 6 is placed between the fixed snap ring 32 and the snap ring 33 of the fixed ring 3, the fixed snap ring 32 in the fixed ring 3 is pressed into the fixed groove 23 at the end of the threaded section of the nut seat 2 to fix the fixed snap ring 32 and the snap ring 33, and a certain movable space is provided for the positioning ring 6 in the state of fig. 1 by the gap between the end of the threaded section of the nut seat 2 and the snap ring 33. During assembly, the conical surface of the head of the quick-insertion straight-through connector 1 is extruded downwards, the positioning ring 6 is forced to move downwards until the convex ring 63 is contacted with the retaining ring 33 to be limited, and at the moment, a certain unfolding space exists between the auxiliary locking clamp spring 4 and the locking clamp spring 5. The conical surface at the head of the quick-connect through connector 1 continues to extrude downwards, the auxiliary locking clamp spring 4 is unfolded firstly, and then the locking clamp spring 5 is unfolded until the positioning clamp ring 52 of the locking clamp spring 5 enters the locking groove 11 and clamps the groove wall of the locking groove 11, namely after the quick-connect through connector 1 is inserted into the nut seat 2, the locking groove 11 of the quick-connect through connector 1 is locked by the locking clamp spring 5 in the positioning ring 6, so that the quick-connect through connector 1 is fixed in the nut seat 2 and does not fall off, the auxiliary locking clamp spring 4 limits the sliding space of the quick-connect through connector 1 in the nut seat 2, and the locking clamp spring 5 is prevented from falling off. The dust ring 13 is compressed when the quick-connect through connector 1 is extruded downwards in the process, after the locating snap ring 52 of the locking clamp spring 5 clamps the groove wall of the locking groove 11, the compressed dust ring 13 starts to rebound to drive the quick-connect through connector 1 to reset to the position shown in fig. 1, and meanwhile, the locking clamp spring 5 clamps the groove wall of the locking groove 11 due to the fact that the locking clamp spring 5 clamps the groove wall of the locking groove 11, the locking clamp spring 5, the locating ring 6 and the auxiliary locking clamp spring 4 rebound together with the quick-connect through connector 1 until the position shown in fig. 1. The cooperation of the inclined surface part of the convex ring 63 shown in fig. 5 and the inclined surface part of the fixing groove 23 shown in fig. 8 plays a role in guiding the resetting of the positioning ring 6, so that the rebound process of the positioning ring 6 is stable. After the positioning ring 6 is reset, the auxiliary locking clamp spring 4 and the locking clamp spring 5 lose the unfolding space, and the groove wall of the locking groove 11 is firmly locked. Finally, the nut seat 2 is fixed on the pipe seat 7 through the matching of the internal thread and the external thread, so that the whole assembly is completed.
When the pipe is required to be disassembled, whether the pressurization exists in the pipe is checked, then the pipe seat 7 and the nut seat 2 are unscrewed, the special clamp is used for clamping the groove 31 outside the fixed ring 3, and the fixed ring 3 is disassembled by pulling outwards with force. Then the disassembly hook is inserted from the gap existing in the snap spring positioning groove 61 on the positioning ring 6, and the locking clamp spring 5 is pulled out from the side surface, so that the locking of the locking clamp spring 5 and the groove wall of the locking groove 11 is released. And then the positioning ring 6 is moved downwards until the auxiliary locking clamp spring 4 obtains the unfolding space. Then the disassembly hook is inserted from the gap existing in the auxiliary clamp spring positioning groove 62 on the positioning ring 6, the auxiliary locking clamp spring 4 is pulled out from the side face, the positioning ring 6 is taken out from the head of the quick-insertion through joint 1, at the moment, the quick-insertion through joint 1 can be pulled out from the nut seat 2, and finally other parts are taken down.
Before the assembly, it is necessary to check whether the nut seat 2 and the first seal ring 12, the second seal ring 24 and the dust ring 13 are damaged.
The foregoing describes in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the invention by one of ordinary skill in the art without undue burden. Therefore, all technical schemes which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the technical personnel in the field according to the conception of the invention are within the protection scope of the invention.
