The specific embodiment
Deluge alarm valve by: valve body (1), valve seat (2), bolt (3), valve gap (4), barrier film (5) form; Valve gap, barrier film and valve body are by bolted, and the valve seat interference is embedded in the valve body groove; Sealing is closed in the pressurization of diaphragm cavity water-filling, and diaphragm cavity sluices to open and supplies water.Fire water supply enters diaphragm cavity at ordinary times, props up valve seat at diaphragm cavity Water Pressure lower diaphragm plate, and the three seals convex line that arranges on equatorial line outside barrier film contacts with valve seat, realizes multi-sealed; Be provided with reinforcement projection backing plate with the vertical orientations of equator sealing convex line, backing plate contacts with the brace rod of valve body, has improved the shearing force status of barrier film in valve body brace rod both sides; Enhancing bulge loop and the radial reinforcement at barrier film indent middle part, the drum when science has evenly been born diaphragm seal is protruding stressed.During unlatching, to the operation of valve gap cavity, current are gushed and go toward the valve body delivery port through the gap outside valve seat and barrier film under the promotion of source pressure for venting diaphragm cavity pressure, barrier film; Reset when closing, press in the diaphragm cavity water filling, barrier film moves to valve seat and closes, recovers sealing under the promotion of source pressure.
Valve body: be designed to straight-through structure, transfer chamber adopts collar plate shape heavy in section flow passage structure, and transfer chamber and valve body Inlet and outlet water axis are perpendicular, have shortened the overcurrent stroke, have reduced the flow resistance loss, have dwindled appearance and size.
Barrier film: be designed to the peviform structure, adopt multilayer to strengthen cloth inserted ethylene propylene diene rubber compression molding, be provided with the three seals convex line on the equatorial line of the barrier film outside, be provided with reinforcement projection backing plate with the vertical orientations of equator sealing convex line, the indent middle part is adopted and is strengthened bulge loop, and in indent, mind-set enhancing bulge loop offers 8 radial uniform reinforcements; The ability of strengthened the intensity when water-pressure sealed, the protruding distortion of anti-drum, separating, breaking has solved conventional barrier film intensity low, and the easily protruding distortion of drum under pressurized, the hidden danger of separating, breaking increase the service life.
