BALL VALVE IMPEDANCE SEAT |
摘要 |
<p>An impedance seat (10) having an impedance element (19) that can be mounted in conjunction with a seat in a ball valve (52). The impedance seat has a concave surface (16) matching the curvature of the ball (76) and a plurality of flow paths (18) formed through it. An impedance assembly can have a plurality of stacked plates (34) that define the flow paths. The impedance seat can have a full flow window (104) having a radius that matches the profile of a flow bore (86) of the ball valve in an intermediate position. The impedance seat can be easily fabricated to provide improved impedance characteristics, and can be used in an original ball valve, or in a retrofit for an existing valve.</p> |
