Problems solved by technology

Although the existing fire dampers can meet the requirements of use to a certain extent, because the blades are all flat blades with a "one" shape, they still have the defect of not being tightly closed.
When the regulating valve is automatically closed, it cannot effectively block the smoke and fire due to the lax closure.

Abstract

The invention discloses a fire valve which comprises a valve body. A flue gas channel is formed in the valve body; a vane mechanism is arranged in the flue gas channel and comprises at least two vanes arranged in the flue gas channel side by side; a rotating shaft is arranged in the middle of each vane; the two ends of each rotating shaft are mounted on the side wall of the flue gas channel in a rotating fit mode; bending joint parts are arranged on the two sides of each vane correspondingly; the bending joint parts arranged on the same vanes are located on the two sides of the planes where the vanes are located; the valve body is provided with an actuator used for driving the vanes to rotate; and a temperature sensor which is electrically connected with the actuator and used for detecting the temperature in the flue gas channel is arranged in the flue gas channel. When the vanes are closed, the bending joint parts of the adjacent vanes can be attached together, and the bending joint parts of one vane can shield the closing seams between the two vanes, so that the airtight performance is effectively improved, and the functions of smoke isolation and fire retardance are better achieved.

Description

technical field [0001] The invention belongs to the technical field of building fire protection equipment, and in particular relates to a fire damper. Background technique [0002] Building fire prevention is the fire prevention measures of buildings. Fire prevention measures should be taken in architectural design to prevent fires and reduce fire hazards to life and property. Building fire prevention includes two aspects: prevention before fire and measures during fire. The former is mainly to determine the fire resistance level and structure, control the amount of combustibles and separate the fire site, etc.; the latter is mainly to carry out fire protection zones, set up evacuation facilities and smoke exhaust , fire extinguishing equipment, etc. [0003] The fire damper is generally installed in the central air-conditioning duct system or mechanical smoke exhaust system. When the temperature reaches the set temperature, it closes, and meets the requirements of smoke l...
