Abstract
A tool having segments forming a triangle wherein a connecting bolt segment moves the other two segments together, thus rotating a valve nut, is disclosed. The tool can be attached and easily operated without the disadvantage of having to apply physical strength in an awkward position. Different embodiments are provided that are adaptable to various valve body types.
Claims10
A tool for rotating a nut adjacent to a valve body comprising:
- a valve body segment;
- a ferrule nut segment;
- and
- a threaded connecting bolt connecting the valve body segment and the ferrule nut segment approximately at respective distal ends, wherein the valve body has an inlet and an exit port offset by approximately 90 degrees, and wherein the nut is adjacent to the valve body inlet, wherein the valve body segment has a proximal end removably secured to the valve body, wherein the ferrule nut segment has a proximal end removably secured to the nut, and wherein the threaded connecting bolt is rotated in operation of the tool to improve a leverage in applying a torque to the nut.

A tool for rotating a nut adjacent to a valve body comprising:
- a valve body segment;
- a ferrule nut segment;
- and
- a threaded connecting bolt connecting the valve body segment and the ferrule nut segment approximately at respective distal ends, wherein the valve body defines an three dimensional axis (x-y-z), wherein a z axis together with a y-axis together define an inlet and outlet port, respectively, wherein the valve body segment, the ferrule nut segment and connecting bolt lie substantially in an x-y plane, wherein the valve body segment has a proximal end removably secured to the valve body, wherein the ferrule nut segment has a proximal end removably secured to the nut, and wherein the threaded connecting bolt is rotated in operation of the tool to improve a leverage in applying a torque to the nut.
1 more element
A system for loosening a nut adjacent to a valve body comprising:
- a first wrench having a handle portion and a curved head for engaging the nut;
- a second wrench having a handle portion and an curved head for engaging the valve body;
- and
- a connecting bolt configured between the first wrench and the second wrench, wherein the first wrench comprises a slot through the handle portion to receive the connecting bolt.
