Abstract

A tool for torquing a regulator onto a cylinder of a portable cylinder assembly. The tool includes a nut and a socket. The nut is configured to fit around a body of a regulator of a portable cylinder assembly. As such, the nut has a first set of grooves that avoids one or more valve assemblies on the body of the regulator. The socket has a cavity extending therethrough such that the cavity consists of three sections: a top section, a middle section and a bottom section. The top section of the socket is configured to be coupled to a device that applies a torque force on the socket. The middle section of the socket is configured to avoid a case of the regulator which is disposed above the body of the regulator. The bottom section of the socket is configured to be coupled to the nut.

First claim

What is claimed is:

1. A method for torquing a regulator onto a cylinder of a portable cylinder assembly, the method comprising:
coupling a nut to a body of the regulator, wherein the nut includes a first set of grooves on an edge of the nut extending from an exterior surface of the nut to an interior surface of the nut, wherein the interior surface of the nut at least partially defines a through-hole in the nut, and wherein coupling the nut comprises attaching two or more pieces of the nut together to form the nut around the body of the regulator, wherein the regulator is configured to control a flow of gaseous materials from the cylinder;
coupling a socket to the nut in a manner that avoids a case of the regulator;
coupling a device to the socket, wherein the device is configured to apply a torque force on the socket; and
applying the torque force on the socket using the device.

2. The method of claim 1 , wherein the first set of grooves is configured to avoid contacting one or more valves protruding from the body and wherein a bottom section of the socket comprises a second set of grooves that corresponds to the first set of grooves so that both the first and second sets of grooves are configured to avoid contacting the valves protruding from the body.

3. The method of claim 1 , wherein the nut comprises two pieces, wherein each of the two pieces is shaped as a half-hexagon.

4. The method of claim 1 , wherein the device is a ratchet.

5. The method of claim 1 , wherein the pieces are assembled such that an inside wall of the nut fits flush against an outside wall of the body.

6. The method of claim 1 , wherein the nut is coupled to the body in a manner that avoids one or more valves protruding from the body.

7. The method of claim 1 , wherein the first set of grooves are configured to avoid contacting one or more valves protruding from the body.

8. The method of claim 1 , wherein the socket comprises a second set of grooves that are configured to avoid contacting one or more valves protruding from the body.

9. The method of claim 1 , wherein the socket comprises a cavity extending through the socket, wherein the cavity comprises:
a top section for coupling to the device;
a middle section that avoids the case; and
a bottom section for coupling to the nut.

10. The method of claim 9 , wherein the bottom section is configured to fit flush against an outside wall of the nut.

11. The method of claim 1 , wherein the device is a torque wrench.

12. The method of claim 1 , wherein applying the torque force to the nut causes the body of the regulator to couple to the portable cylinder.

13. The method of claim 12 , wherein applying the torque force to the nut does not alter a torque value between the case of the regulator and the body of the regulator.

14. A method for torquing a regulator onto a cylinder of a portable cylinder assembly, the method comprising:
coupling a plurality of nut portions together to form a nut around a body of the regulator, the nut portions including a set of grooves on an edge surface of the nut extending from an exterior surface of the nut to an interior surface of the nut, wherein the interior surface of the nut at least partially defines a through-hole in the nut;
coupling a socket to the nut in a manner that avoids a case of the regulator; and
applying a torque force on the socket.

15. The method of claim 14 , wherein each groove of the set of grooves is semi-circular shaped such that the nut would fit around the body of the regulator without contacting one or more valves protruding from the body.

16. The method of claim 15 , wherein the nut is shaped as a hexagon.

17. The method of claim 15 , wherein the socket comprises a plurality of grooves, wherein each of the plurality of grooves corresponds to one of the one or more semi-circular shaped grooves of the nut.

18. The method of claim 14 , wherein the regulator includes one or more valves protruding from the body through one or more of the set of grooves of the nut.

19. A method for torquing a regulator onto a cylinder of a portable cylinder assembly, the method comprising:
coupling a nut to a body of the regulator, wherein the nut includes a first set of grooves on an edge of the nut extending from an exterior surface of the nut to an interior surface of the nut, wherein the interior surface of the nut at least partially defines a through-hole in the nut, and wherein coupling the nut comprises attaching two or more pieces of the nut together to form the nut around the body of the regulator;
coupling a socket to the nut in a manner that avoids an entire case of the regulator;
coupling a device to the socket, wherein the device is configured to apply a torque force on the socket; and
applying the torque force on the socket using the device.

20. The method of claim 19 , wherein the regulator is configured to control a gas flow from the cylinder.
