Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a sealing structure of a valve. Background Art

[0002] Valves are commonly used components for pipeline connections and are widely used. At present, in order to ensure the sealing between valves and valves and between valves and pipelines, sealing gaskets are usually set on the connecting surfaces of the valves. The connecting surfaces of the valves squeeze the sealing gaskets from both sides to achieve a better sealing effect.

[0003] Chinese patent announcement No. CN217463281U discloses a sealing structure of a valve, including a main sealing mechanism and a secondary sealing mechanism, wherein a fitting mechanism for sealing a rod body is arranged in the middle of the inner side of the main sealing mechanism, and the secondary sealing mechanism for sealing the flow port is arranged in the middle of the inner lower side of the main sealing mechanism, and a limiting mechanism for anti-slip is installed inside the upper side of the main sealing mechanism. Compared with the existing device, the sealing structure of the valve can lock and fix the position of the valve stem during use through a telescopic column, a third spring, a limiting rod and a locking groove, thereby avoiding radial sliding of the rod body due to long-term operation, which causes the bottom to move up and cause leakage. Through the locking groove, multiple groups of them are closely arranged, so that the matching locking ability can be maintained when the rod body moves. Through the pull plate and the rotating seat, the limit rod can be pulled out of use, so that the rod body can restore its rotation ability. At the same time, the pull plate is released, and the limit rod can automatically engage and limit.

[0004] However, the utility model has the following problems when actually used:

[0005] 1. The utility model cannot better clamp and fix the internal parts when the whole device is used, which easily causes rotational wear between parts, resulting in poor durability of the parts;

[0006] 2. The utility model cannot better perform external protection when the entire device is in use, which causes the device to easily shift position after long-term use, and the stability of the device needs to be improved. Utility Model Content
