Summary: | Disclosed are an assembly for preventing clamping stagnation of a valve rod, and a valve structure and method for preventing clamping stagnation of a valve rod. The assembly for preventing clamping stagnation of a valve rod includes a rigid ring and an elastic ring. The rigid ring is coaxially sleeved in the elastic ring, and the inner wall of the rigid ring is of a straight cylindrical structure. A valve rod can move up and down along the inner wall of the rigid ring under the guidance of the rigid ring and forms a sliding pair together with the rigid ring. The joint between the rigid ring and the valve rod is closed. The assembly for preventing clamping stagnation of a valve rod is simple in structure, convenient to manufacture, and suitable for most valves having elongated valve rod structures. |
