A VALVE BODY FILTRATION SYSTEM |
| 摘要 |
A gate valve includes a valve body with a How passage intersected by a gate cavity. The gate valve also includes, a gate with an axis, a downstream gate face, and an upstream gate face on an opposite side. The gate is axially movable in the gate cavity between a gate closed position and a gate open position. A seat ring is located between each gate face and the valve body, at the intersection of the flow passage and the gate cavity. An annular seal is located between each of the seat rings and the valve body. At least one annular filter is located between at least one of the seat rings and the valve body, each of the at least one filters being located radially inward from one of the seals relative to an axis of the flow passage. |
