When the second piston 10 collides against the terminating part 11, it is indicated that the second piston 10 moves to the final position, and meanwhile, the second piston 10 can well abut against the end part of the oil inlet pipe 3, so that even if the lubricating oil in the oil inlet pipe 3 has a certain pressure, the lubricating oil can be prevented from continuously entering the limiting cylinder 2; also, since the end portion 11 is annular, the lubricating oil can be normally introduced into the cylinder 1. Wherein, because the first piston 5 and the second piston 10 are both in contact with the lubricating oil, the first piston 5 and the second piston 10 can have smaller resistance when moving, and the burden on the first cylinder 4 and the second cylinder 9 is smaller.
When the plug valve is filled with grease, firstly, the plug valve to be filled with grease is placed in the supporting groove 25, and the shape of the supporting groove 25 is close to or matched with the shape of the bottom of the plug valve, so that the plug valve can keep better position stability (not necessarily completely clamped);
