Safety connection connecting a vessel containing a gas under pressure to a discharge system |
摘要 |
A safety connection located between a vessel containing a gas under pressure and a gas discharge system comprises a pilot controlled valve which is provided with a separate control system for opening the valve, the valve having a ball-and-socket system between the actuating rod and the valve-closing flap which it carries, so that the valve can also function as a sluice so as to avoid the need to provide a second pipe connected to the vessel and provided with a sluice as is conventional. The actuating rod of the valve carries a piston, one face of which is normally subject to the pressure of fluid in the vessel via the pilot valve but is connected to a vent as soon as an overpressure occurs, to open the valve. The other face of the piston is normally connected to a vent but is subject to the pressure of a fluid from an independent source of control fluid when the separate control system is operated to open the valve. |
