Abstract
In some examples, a pressure reducing valve includes a valve body defining a defining a flow path and a restricting element within the flow path. A sensing element is configured to modify a position of the restricting element in the flow path. A pressure chamber is configured to transmit a force to the sensing element based on the pressure of a fluid within the pressure chamber. An energy accumulator is in fluid communication with the pressure chamber. The pressure reducing valve includes control circuitry configured to enable a fluid to flow into or discharge from the pressure chamber to alter the pressure in the pressure chamber.
Claims18
A valve comprising:
- a restricting element;
- a valve body defining a pressure chamber;
- one or more valves in fluid communication with the pressure chamber, wherein the one or more valves are configured to enable a fluid having a fluid energy to flow to the pressure chamber;
- a sensing element configured to position the restricting element using a first portion of the fluid energy;
- and
- an energy accumulator configured to generate stored energy using a second portion of the fluid energy,
- wherein the energy accumulator comprises:
- an elastic member having a first end and a second end;
- and
- a plate;
- wherein the elastic member is configured to be compressed between the plate and the sensing element;
- wherein the energy accumulator is configured to translate the plate using the fluid energy in the pressure chamber to generate a compression of the elastic member between the first end and the second end;
- wherein the pressure chamber is configured to deliver the first portion of the fluid energy to the sensing element, and
- wherein the pressure chamber is configured to deliver the second portion of the fluid energy to the energy accumulator.
A valve comprising:
- a valve inlet;
- a valve outlet;
- a restricting element between the valve inlet and the valve outlet;
- a valve body defining a pressure chamber;
- an inlet pressure line between the valve inlet and the pressure chamber;
- an outlet pressure line between the valve outlet and the pressure chamber;
- one or more valves in fluid communication with the pressure chamber, wherein the one or more valves are configured to:
- enable a fluid having a fluid energy to flow from the valve inlet to the pressure chamber through the inlet pressure line, and
- configured to enable the fluid in the pressure chamber to discharge from the pressure chamber to the valve outlet through the outlet pressure line;
- a sensing element configured to position the restricting element using a first portion of the fluid energy;
- and
- an energy accumulator configured to generate stored energy using a second portion of the fluid energy, wherein:
- the energy accumulator comprises:
- an elastic member having a first end and a second end;
- and
- a plate;
- wherein the elastic member is configured to be compressed between the plate and the sensing element;
- the energy accumulator is configured to translate the plate using the fluid energy in the pressure chamber to generate a compression of the elastic member between the first end and the second end;
- the pressure chamber is configured to deliver the first portion of the fluid energy to the sensing element,
- the pressure chamber is configured to deliver the second portion of the fluid energy to the energy accumulator, and
- the energy accumulator is configured to exert a pressure on the fluid in the pressure chamber using the stored energy.
