Abstract
A flow valve includes a control valve having a movable body, a stop valve having a movable body; and a valve seat having a facing surface that contacts at least a portion of one of the control valve body or the stop valve body when the flow valve is in a closed position, the facing surface of the valve seat being configured to merge with a rear portion of the valve seat at a tip portion, the facing surface of the valve seat having an aerodynamic profile that provides for a guided flow in a flow direction through the flow valve.
Claims17
A flow valve, comprising:
- a control valve having a movable body;
- a stop valve having a movable body;
- and
- a valve seat having a facing surface that contacts at least a portion of one of the control valve body or the stop valve body when the flow valve is in a closed position, the facing surface of the valve seat being configured to merge with a rear portion of the valve seat at a tip portion, the facing surface of the valve seat having an aerodynamic profile that provides for a guided flow in a flow direction through the flow valve.
A flow valve, comprising:
- an inlet through which a flow of steam flows into the flow valve;
- an outlet through which the flow of steam exits the flow valve;
- one of a control valve having a movable body or a stop valve having a movable body;
- and
- a valve seat having a facing surface that contacts at least a portion of the one of the control valve body or the stop valve body when the flow valve is in a closed position, the facing surface of the valve seat being configured to merge with a rear portion of the valve seat at a tip portion, the facing surface of the valve seat having an aerodynamic profile that provides for a guided flow in a flow direction through the flow valve.
