Abstract
Embodiments of an apparatus that provide functions to set and to verify the set point of a valve assembly in a single device. These embodiments forgo the need to use of two separate devices, one each to accomplish the tasks to set the set point and to verify the set point. Rather, the apparatus incorporates components that can assume different configurations including a first configuration that facilitates the task for setting the set point and a second configuration that facilitates the task of verifying the set point.
Claims19
An apparatus comprising:
- a force directing component configured to couple with a bonnet on a valve assembly, the force directing component having a first configuration and a second configuration that is different from the first configuration, each configuration operative so that, when in position on the bonnet, the force directing component is configured to transfer a load from a lift member to a spring member on the valve assembly,
- wherein the first configuration configures the force directing component to transfer the load from the lift member to compress the spring member in a first direction, and
- wherein the second configuration configures the force directing component to direct the load from the lift member to compress the spring member in a second direction that is the opposite of the first direction,
- wherein the force directing component comprises a first member with a shaft that has a first end that is configured to couple with a spindle on the valve assembly and a second end that is configured to extend through the lift member.
1 more element
An apparatus, comprising:
- a load member comprising a piston moveable in a cylinder;
- a plate coupled with cylinder;
- a spindle connection member extending through the cylinder and the piston, the spindle connection member having a first end and a second end that connects to a spindle on a valve assembly;
- a plunger connection member receiving the second end of the spindle connection member and the spindle;
- and
- a force-directing member coupled to the plunger connection member,
- wherein the force-directing member is configured to rotate to change positions on the plunger connection member,
- wherein the positions include a first position and a second position, one each to cause the piston to defect a spring on the valve assembly in opposite directions.
5 more elements
A method, comprising:
- adjusting a valve assembly comprising a spindle, a disc member attached to a first end of the spindle, a nozzle, a spring, and a bonnet enclosing the spindle, the disc member, the nozzle, and the spring, by:
- securing an apparatus to the bonnet of the valve assembly, the apparatus comprising a load member with a piston movable in a cylinder;
- and
- operating the load member while attached to the valve assembly to set and to verify deflection of the spring,
- wherein the apparatus has a first configuration that allows the piston to extend toward the nozzle so as to cause the spring to deflect in a first direction with the disc member against the nozzle, and
- wherein the apparatus has a second configuration that prevents the piston from extending toward the nozzle so as to cause the spring to deflect in a second direction to cause the disc member to move away from the nozzle.
