Description

Technical Field

[0001] This invention belongs to the field of gate valve manufacturing technology, specifically relating to a gate valve core assembly device. Background Technology

[0002] A gate valve is a valve in which the closing element (valve core) moves along the centerline of the valve seat. (See also...) Figure 1 and Figure 2 The valve core of an existing gate valve is formed by assembling a valve body 100, a core 200, a valve stem 300, a gasket 400, an O-ring 500, and a retaining ring 600. The assembly process includes the following steps: (1) inserting the gasket 400 into the cavity of the valve body 100; (2) fitting the O-ring 500 onto the top outer wall of the valve body 100; (3) threading the core 200 to the first end of the valve stem 300; (4) inserting the combination of the core 200 and the valve stem 300 into the cavity of the valve body 100, so that the second end of the valve stem 300 protrudes from the bottom of the valve body 100; (5) engaging the retaining ring 600 into the groove of the valve stem 300 along the bottom end face of the valve body 100.
