Claims20
A valve stem comprising:
- a valve stem body having an expandable tip;
- and
- a valve stem head defining an opening configured to receive the expandable tip, wherein upon insertion of the expandable tip into the opening in the valve stem head the expandable tip expands radially outwardly to attach the valve stem body to the valve stem head.
A choke valve comprising:
- a valve body defining a flow inlet and a flow outlet and a flow passage communicating the flow inlet and flow outlet;
- a valve seat in the valve body, the valve seat positioned between the flow inlet and the flow outlet;
- a valve stem disposed in the valve body and operable with the valve seat to regulate flow through the flow passage, the valve stem comprising;
- a valve stem head defining an opening in an end thereof;
- a valve stem body;
- and
- a valve stem tip movable from a relaxed position to an expanded position extending from the valve stem body, wherein the valve stem tip radially expands to an expanded position in the opening in the valve stem head, and wherein the valve stem head is secured to the valve stem body when the valve stem tip is in the expanded position.
A choke valve stem for use in a choke valve designed to regulate flow comprising:
- a valve stem head defining an opening therein;
- a valve stem body having first and second ends;
- a segmented valve stem tip movable from a relaxed position to an expanded position, the valve stem tip extending from the second end of the valve stem body and received in the opening in the opening in the valve stem head, wherein the valve stem tip moves to the expanded position when it is received in the opening in the valve stem head and secures the valve stem body to the valve stem head.
The choke valve stem of claim 20, wherein the valve stem tip is secured to the valve stem body when the insert urges the expandable tip to the expanded position.
