WELL GATE VALVE GREASING TOOL AND METHOD OF USE

摘要

A grease tool (63) lubricates a valve (11) having an actuator assembly (33) for moving a valve element (25) of the valve. The tool has a housing (65) with a piston (81) carried in a bore (71). The housing is open for inserting and sealing a portion of the actuator assembly (45 within 33) into the bore. A fill port (93) in the housing allows grease to be introduced into the bore. A piston rod (85) joins the piston and has external threads engaging internal threads of the housing, so that rotating the piston rod causes the piston to move axially. A lever (101) is mounted to the housing for imparting rotation to the housing. A lock pin (79) extends through a side wall of the housing to engage the actuator assembly to cause the actuator assembly to rotate in unison with the housing.
