Embodiment 1
[0072] Take the metal sealing ring at the female end of the small conduit connector such as Figure 7 shown. The convex step combination is matched with the female end 17 of the small conduit connector, wherein the end of the small conduit connector is inlaid with a metal sealing ring 5, and the female end 17 of the small conduit connector is held by an open-end wrench, and the tooling outer nut 4 is tightened clockwise with another open-end wrench , and a torque of 50N·m is applied. At this time, the metal sealing ring is located between the small conduit joint and the top shaft 6, and is deformed under pressure. hook structure such as Figure 10 shown. Then loosen the tooling overcoat nut 4 with a wrench, pull the pull shaft 7 out by pulling the pull plate assembly, and the metal sealing ring is pulled out. At this time, loosen the wing nuts 11, 14, and separate the upper pressing block 9 and the lower pressing block 8, so that the drawing plate assembly can be separated ...
Embodiment 2
[0074] Take the metal sealing ring at the male end of the small conduit connector such as Figure 8 shown. The concave step combination is matched with the male end 16 of the small conduit joint, wherein the small conduit joint end is inlaid with a metal sealing ring 5, and the pull sleeve 3 is held by an open-end wrench, and the small conduit male end is tightened clockwise with the jacket Nut 15, and apply a 50N·m torque, at this time, the metal sealing ring is located between the small conduit joint and the top sleeve 2, deformed under pressure, the outer diameter of the metal sealing ring becomes larger, and embedded in the hole-shaped ring hook of the pull sleeve 3, Hole ring hook structure such as Figure 9 shown. Then loosen the overcoat nut 15 at the male end of the small conduit with a wrench, and pull the pull sleeve 3 out by pulling the pull plate assembly, and the metal sealing ring is pulled out. At this time, the wing nuts 11 and 14 are loosened, and the upper...
