Abstract
A valve body including an inlet pipe, an outlet pipe, a valve body, a flow channel formed in the valve body. A valve plug unit has a stem, a wing, and a plug arranged along a longitudinal access of the valve plug unit, the plug being arranged to be rotatable in a plug housing formed in the flow channel. A bypass inlet is arranged in the outlet pipe to facilitate fluid flow to and from the reservoir. A bypass outlet nozzle is arranged in a wall of the chamber, the bypass outlet nozzle configured and arranged such to direct a fluid jet stream at a surface of the wing that is fixedly connected to the stem of the valve plug unit to thereby rotate the wing from a first position to a second position, the bypass outlet nozzle being fluidically connected to the reservoir via a bypass.
Claims10
A valve body comprising:
- an inlet pipe;
- an outlet pipe;
- a valve body;
- a flow channel formed in the valve body, the flow channel facilitating fluid flow from the inlet pipe to the outlet pipe;
- a chamber;
- a valve plug unit having a stem, a wing, and a plug, the plug being arranged along a longitudinal axis of the valve plug unit, the plug being arranged to be rotatable in a plug housing formed in the flow channel, a rotation of the valve plug unit from a closed position to an open position facilitating fluid flow through the flow channel from the inlet pipe to the outlet pipe, the wing being rotatably arranged in the chamber, the chamber and the valve body being sealingly arranged from one another along the longitudinal axis of the valve plug unit;
- a reservoir arranged between the chamber and the outlet pipe;
- a bypass inlet arranged in the outlet pipe to facilitate the fluid flow to and from the reservoir;
- and
- a bypass outlet nozzle arranged in a wall of the chamber, the bypass outlet nozzle configured and arranged such to direct a fluid jet stream at a surface of the wing that is fixedly connected to the stem of the valve plug unit to thereby rotate the wing from a first position to a second position, the bypass outlet nozzle being fluidically connected to the reservoir via a bypass.
