Valve device and method for preventing explosion propagation |
摘要 |
A valve device includes a housing and a closing body for closing a passage in the housing in mechanical manner, wherein the closing body is movable between an open position and a closing position; a reservoir for a flame-extinguishing substance; and an injecting means configured to inject the flame-extinguishing substance into the passage in order to prevent explosion propagation resulting from a non-fully sealed closure by the closing body. |

1. A valve device for preventing explosion propagation, comprising:
a housing and a closing body for closing a passage in the housing in mechanical manner, wherein the closing body is movable between an open position and a closing position; an actuator configured to move the closing body from the open position to the closing position in less than 100 ms; a reservoir for a flame-extinguishing substance; and an injecting means configured to inject the flame-extinguishing substance into the passage in order to prevent explosion propagation resulting from a non-fully sealed closure by the closing body, wherein the reservoir is a closed reservoir in which the flame-extinguishing substance is stored under pressure, wherein the injecting means comprises an opening mechanism for opening the reservoir, and wherein the distance between the opening mechanism and a point of injection of the flame-extinguishing substance into the passage is less than 20 cm. |
