Filed:

Mar 30, 2005

Appl. No.:

11/095463

Inventors:

Peter Karalis - Watertown MA, US
Raymond A. Stacy - Framingham MA, US
Richard Zaven Karadizian - Westford MA, US
James E. Marquedant - Mendon MA, US

Assignee:

Kidde-Fenwal Inc. - Ashland MA

International Classification:

F16K 25/00

US Classification:

251193, 251 89, 280740, 280741

Abstract:

A device and method for locking out an explosion suppressor that includes a discharge valve with a load end and a discharge end. The load end and the discharge end define a discharge path therethrough. The discharge valve includes a side opening transverse of the discharge path. A storage container is connected to the discharge valve at the load end. The storage container delivers a pressurized fluid to the discharge valve through the load end when the system is in a discharge mode. A lockout member is removably insertable into the side opening. The lockout member mechanically blocks the discharge path, whereby the lockout member prevents inadvertent fluid discharge through the discharge end of the discharge path. The presence of the lockout member is monitored by a magnetic switch.

International Classification:

F16K017/40

US Classification:

137068130

Abstract:

An apparatus and method for rapid fluid venting that includes a burst seal disposed in a venting aperture. The burst seal seals the venting aperture so that fluid flow therethrough is not enabled. A piston defining at least one piston aperture therethrough, the piston being movably disposed proximate the burst seal. At least one actuator, actuatable between a first configuration and a second configuration. The actuator is engaged with the piston such that when the actuator actuates from the first configuration to the second configuration, the actuator impels the piston so that the piston ruptures the burst seal. With the burst seal ruptured, the piston aperture and the venting aperture are in communication so as to enable fluid flow through the venting aperture and the piston aperture.

Abstract:

An apparatus and method for dispensing fluid including a pressure vessel at a first pressure and a reservoir at a second pressure. The reservoir communicates with the pressure vessel via a first aperture and with an environment at a third pressure via a second aperture. A reservoir vent having open and closed positions, that when opened the reservoir vents to a fourth pressure, and when closed the reservoir does not vent. A piston moveably disposed within the reservoir, and defines an aperture therethrough. A first burst seal disposed in the first aperture seals the pressure vessel from the reservoir, and engaged with the piston to be moveable therewith. A second burst seal disposed in the second aperture seals the reservoir from the environment. When the reservoir vents to the fourth pressure, the piston ruptures the second seal, and a first and third pressure difference ruptures the first seal.
