VALVE STEM REPAIR KIT AND METHOD |
摘要 |
A method for repairing damaged valve stem assemblies includes enlarging a bore within a body of a valve stem to form an enlarged bore portion and creating a conical hole in an end of the valve stem body around the enlarged bore portion. Internal threads are created within the enlarged bore portion, and a valve stem repair extension is installed in the enlarged bore portion. The valve stem repair extension has a beveled surface that mates with the conical hole to form a hermetic seal between the valve stem body and the valve stem repair extension. The steps of enlarging the bore and creating the conical hole may both be performed using a countersinking drill bit having a beveled cutting portion. |
