Abstract
A valve for use in a gas turbine. The valve includes at least one valve body, at least first, second and third fluid delivery pipes positioned on the valve body, at least one outlet pipe positioned on the valve body and a rotatable spherical shutter inside the valve body (and including first and second distribution channels formed within the shutter so as to allow the outlet pipe to be selectively connected to one of the delivery pipes during rotation of the shutter.

A valve for use in a turbine, the valve comprising:
- a valve body;
- at least first, second and third fluid delivery pipes positioned on the valve body;
- at least one outlet pipe positioned on the valve body;
- and
- a rotatable spherical shutter inside the valve body and comprising first and second distribution channels formed on the shutter such that:
- in a first position of the shutter, the first distribution channel is configured to allow fluid communication between the first delivery pipe and the outlet pipe;
- in a second position of the shutter, the first distribution channel is configured to allow fluid communication between the second delivery pipe and the outlet pipe;
- and
- in a third position of the shutter, the second distribution channel is configured to allow fluid communication between the third delivery pipe and the outlet pipe.
A supply system for a turbine comprising at least one fuel chamber configured to be supplied with liquid fuel, the supply system comprising:
- a liquid fuel inlet means;
- a drain liquid inlet means;
- a drain gas inlet means;
- and
- a valve comprising
- at least first, second and third fluid delivery pipes positioned on the valve body;
- at least one outlet pipe positioned on the valve body;
- and
- a rotatable spherical shutter inside the valve body and comprising first and second distribution channels formed on the shutter such that:
- in a first position of the shutter, the first distribution channel is configured to allow fluid communication between the first delivery pipe and the outlet pipe;
- in a second position of the shutter, the first distribution channel is configured to allow fluid communication between the second delivery pipe and the outlet pipe;
- and
- in a third position of the shutter, the second distribution channel is configured to allow fluid communication between the third delivery pipe and the outlet pipe (20),
- wherein the first, second and third delivery pipes of the valve are connected to the liquid fuel inlet means, the drain liquid inlet means and the drain gas inlet means respectively.
