Description

Technical Field

[0001] The utility model relates to the technical field of valve body plugs, and more specifically, to a valve body plug structure. Background Art

[0002] In order to prevent foreign matter from entering the interior of the valve body before the valve body leaves the factory, a corresponding valve body plug is usually installed at the connection end of the valve body.

[0003] Most of the existing valve body plugs are directly inserted into the interior of the valve body. Since there may be a small deviation in the outer diameter of the valve body plug during the production process, after the valve body plug is inserted into the interior of the valve body, the clamping force between the valve body plug and the valve body may be small or large. When the clamping force is small, the valve body plug may fall off, which may easily cause debris to enter the interior of the valve body. When the clamping force is large, it is inconvenient to pull the valve body plug out from the interior of the valve body when installing the valve body. In addition, the existing valve body plug can only block the port of one type of valve body, and is not convenient for blocking the port of valve bodies of different types and diameters, thereby reducing its practicality.

[0030] In this embodiment, the sleeve 1 is sleeved on the outside of the valve body, and then the valve body is clamped and fixed by multiple clamping mechanisms, so that the sleeve 1 can be firmly clamped on the outside of the valve body, and the sleeve 1 can be prevented from falling off the valve body. At the same time, it is convenient to install it on valve bodies of different models, and it is convenient to seal the ports of valve bodies of different models, thereby improving its practicality.
