BLEEDER VALVE FOR PRESSURISED FURNACE |
摘要 |
<p>A bleeder valve for controlling a gas outflow from the interior of a pressurized furnace to the ambient atmosphere through an exhaust conduit is proposed. The bleeder valve comprises a valve seat associated with the exhaust conduit, a movable closure member having a generally convex central closure surface and a peripheral sealing surface cooperating with the valve seat, and an actuating mechanism which is connected to the closure member for moving the closure member between a closed position on the valve seat and an open position distant from the valve seat. According to an important aspect, the closure member comprises a recurved deflection surface at the periphery of the peripheral sealing surface, the recurved deflection surface being shaped so as to impart to a gas outflow passing between the valve seat and the closure member a velocity component which is opposite to the initial opening movement of the closure member.</p> |
