Abstract
A system and method of performing maintenance on a wing cock valve coupled to a pressurized gas delivery pipe is provided. The method removing a plug from a port on the valve. A threaded portion of a grease tool is coupled to the port, the grease tool having a body coupled to the threaded portion and a fitting on an opposite end, the fitting, body and threaded portion defining a flow path. A hose is coupled on a grease gun to the fitting; and actuating the grease gun to flow a grease from a reservoir through the flow path and into the valve.
Claims17
A method of performing maintenance on a cock valve coupled to a pressurized gas delivery pipe, the method comprising:
- removing a plug from a port on the valve;
- coupling a threaded portion of a grease tool to the port, the grease tool having a fitting on an end opposite the threaded portion;
- coupling a hose on a grease gun to the fitting;
- and
- actuating the grease gun to flow a grease from a reservoir through a flow path and into the valve.
A system for performing maintenance on a cock valve coupled to a pressurized gas delivery pipe, the cock valve having a port closed by a plug, the plug having a hexagonal keyway, the system comprising:
- a grease tool having a body with a threaded portion on one end and a fitting on an opposite end, the threaded portion sized to engaged the port, wherein the port is fluidly coupled to a valve internal mechanism and the gas delivery pipe;
- and
- a grease gun having a grease reservoir, a pump mechanism configured to couple with the fitting and flow grease from the grease reservoir into the valve internal mechanism.
A method of performing maintenance on a pressurized gas delivery system, the method comprising:
- providing a cock valve coupled to the pressurized gas delivery system, the cock valve having a port closed by a plug, the plug having a hexagonal recess or keyway;
- removing the plug from the port;
- coupling a threaded portion of a grease tool to the port, the grease tool having a fitting on an end opposite the threaded portion;
- coupling a hose on a grease gun to the fitting;
- stopping the flow of gas through the port when the hose is coupled;
- and
- actuating the grease gun to flow a grease from a reservoir through a flow path and into the valve.
