Description

Technical Field

[0001] The utility model relates to the technical field of valve stem assembly, in particular to an automatic valve stem assembly device. Background Art

[0002] The valve stem is an important part of the valve, used for transmission, connected to the actuator or handle, and directly drives the valve core to move or rotate to achieve the valve opening or closing or regulation. The valve stem is not only a moving part and a force-bearing part, but also a sealing part during the valve opening and closing process.

[0003] When assembling the valve stem of an existing valve body, it is necessary to extend the valve stem into the interior of the valve body from the opening on the top surface of the valve body, and then rotate the valve stem and insert one end into the valve stem hole of the valve body to complete the installation. After the valve stem is installed, the ball is pressed into the valve body to connect the valve stem with the socket of the ball. However, in actual assembly, the valve stem is usually inserted into the valve stem hole by a manipulator driving an electric clamp. After insertion, the electric clamp is likely to touch the valve stem, causing the valve stem to be displaced, so that the valve stem cannot match the socket of the ball when the ball is installed, resulting in the valve stem being scrapped. Therefore, it needs to be improved. Utility Model Content
