Abstract

The invention discloses an automatic reset fireproof valve which comprises a fireproof valve body, fusible pieces, a switch operation box, a single chip microcomputer, a temperature inductor, a motor and gears. An upper connecting block is fixedly welded to the top end in the fireproof valve body, the fusible pieces are fixedly installed on the back face of the upper connecting block, the switch operation box is fixedly installed on the top end surface of the fireproof valve body, a first permanent magnet is fixed to the top ends of the back faces of rotating blades, the single chip microcomputer is fixedly installed on the left side in the switch operation box, the left side of the top end of the switch operation box is connected with a connecting wire, the temperature inductor is fixedly connected to the left side in the fireproof valve body, and the interior of the upper connecting block is connected with the rotating blades through bearing seats. The first permanent magnet is arranged so that the fireproof valve body can be used in various environments, resetting of the rotating blades is guaranteed through a temperature-resistant cavity and a horizontal spring, and the fusible pieces are convenient to install.

Description

technical field [0001] The invention relates to the technical field of fire dampers, in particular to automatic reset fire dampers. Background technique [0002] Smoke exhaust fire damper belongs to fire safety equipment. It is generally installed in the smoke exhaust pipe and is usually open. When a fire occurs, the open state is convenient for smoke exhaust. When the temperature of the smoke in the smoke exhaust pipe reaches a certain temperature, the fire damper When the fusible sheet is blown, the fire damper can be closed automatically. Installing the fire damper between the pipelines of the building can prevent the fire from spreading. It is a necessary equipment in the fire protection system of the building. [0003] At present, the fire damper needs to be manually reset after use, which makes it difficult for the fire damper to automatically reset, which has a certain impact on the use of the fire damper. At the same time, the fusible piece of the fire damper has bee...
