Abstract

The invention discloses a marine fire damper, comprising a fire damper installation valve body frame (1), a rotatable gate (2), a gate operating device (3), a swing rod (4), and an opening spring (5) , a closing spring (6), a peep hole (8) and a temperature sensor (7), and at least one rotatable gate plate ( 2); the rotatable ram (2) is a rotatable ram with a hollow structure; a ram operating device (3) is provided above the valve body frame (1) where the fire damper is installed; the ram operation The device (3) is provided with the opening spring (5) and the closing spring (6). The invention adopts a marine fire damper with a reasonable structural design, which can make the contact position between the rotatable gate plate and the valve body frame of the fire damper play a sealing role, prevent smoke from escaping, and make the sealing effect better.

Description

technical field [0001] The invention relates to the technical field of marine equipment, in particular to a marine fire damper. Background technique [0002] The marine fire damper is a common marine fire-fighting equipment, which is used to automatically close the damper after being placed in the ventilation duct to feel the temperature of the high-temperature gas from the fire zone. It is usually located between two fire prevention areas and is used to cut off the source of fire and cut off the spread of fire. Existing fire dampers include a plurality of rotatable gates, the gates are installed on an installation frame, and the rotation direction of the gates is controlled by an external mechanism, thereby controlling the opening of the damper. When the existing damper is closed, the top and bottom of the damper cannot be sealed, which affects the sealing performance of the damper, and the structural design is unreasonable. Contents of the invention [0003] Aiming at ...
