摘要: front page image
(EN)


A valve for fire suppression sprinkler systems is disclosed. The valve has a
chamber with an inlet and an outlet. A closure member, positioned within the
chamber, is movable to close and open the inlet. A latch engages the closure
member to hold it in the closed position. The latch also engages a deformable
diaphragm. The diaphragm deforms in response to pressure applied to it and
allows the latch to move between a latched position engaged with the closure
member and an unlatched position away from the closure member. When the
diaphragm is depressurized it allows the latch to move and disengage from the
closure member, which opens under fluid pressure from the inlet and allows
fluid to flow through the valve.
