Abstract
An improved stem protector system for valves including an assembly, preferably a sleeve assembly, structured and sized for surrounding a valve stem and for mating with a valve stem actuator, the assembly including at least one port system, the at least one port system having at least one port structure to pass lubricant from outside to inside the system and at least one drainage port to pass water from inside to outside the system. Preferably the lubricant port(s) and the water drainage port(s) are separate.
Claims8
An improved stem protector system for valves, comprising
- a sleeve assembly structured and sized for surrounding a valve stem and for mating with a valve stem actuator, the assembly including
- an outer sleeve fitting around at least a portion of an inner sleeve;
- the inner sleeve having at least one lubrication port therethrough;
- and
- a space between the inner and outer sleeve providing for fluid drainage from inside the assembly to outside the assembly.
An improved stem protector system for valves, comprising
- an assembly structured and sized for surrounding a valve stem and for mating with a valve stem actuator, the assembly including
- at least one lubrication port system, the at least one lubrication port system having at least one port structured to pass lubricant from outside to inside the system;
- and
- at least one drainage port, structured to pass water from inside to outside the system, wherein a drainage port is understood broadly to encompass openings and channels as well as a lubricant port.
A method for protecting and lubricating valve stems, comprising:
- affixing a valve stem cover assembly over a valve stem and to a valve actuator;
- lubricating an interface between the valve stem and a valve actuator portion through a lubrication port provided in the valve stem cover assembly;
- and
- draining water from inside the stem protector assembly to outside the assembly through a drainage port provided by the assembly.
