System for detecting leaks in interstitial chambers

摘要

System which comprises a pneumatic control circuit 8, and pneumatic vacuum or pressure circuit 9 connected to the interstitial chamber 4 by means of a controlled gate valve 10, an electric control circuit 11 and a diaphragm valve 12 which is coupled to the outlet 5 of the interstitial chamber and which forms the closure means of a pressure outlet 13 defined in the pneumatic control circuit 8. This system detects the existence of leaks in the chamber 4 owing to the drops in pressure which the control circuit 8 suffers when the diaphragm valve 12 moves into the position for opening the outlet 13 owing to the drop in the vacuum or pressure inside the chamber 4. <IMAGE>
