Description

Technical Field

[0001] The utility model belongs to the field of fire safety, and particularly relates to a smoke exhaust and fire prevention valve for fire fighting which is convenient to install. Background Technique

[0002] A fire prevention valve is a form of valve based on the temperature control of a fusible alloy and closed by the action of gravity and a spring mechanism. Usually, the fire prevention valve is arranged at the pipe connection. When a fire occurs and the temperature value in the pipe reaches a fixed value, the fire prevention valve makes the valve automatically close through a temperature fuse provided with a fusible metal, thereby cutting off the air flow and preventing the spread of the fire.

[0003] When the existing equipment is installed, the installation is complex, time-consuming and laborious, which affects the work efficiency. At the same time, when installing, the size of the pipe does not match the ventilation pipe, and the equipment needs to be replaced for installation. During the smoke exhaust process, impurities in the smoke are discharged, which affects the outdoor air and causes pollution to the outdoor air. Therefore, we propose a smoke exhaust and fire prevention valve for fire fighting which is convenient to install. Content of the Utility Model

[0033] A specific application of this embodiment is as follows:

[0034] When the staff needs to use the device, when installing the ventilation pipe 1, the push rod 206 can be pushed. When the push rod 206 is pushed, it drives the connecting rod 205 to move. After the connecting rod 205 is pushed to an appropriate size, the connecting rod 205 is inserted into the interface for connection. After the connecting rod 205 is connected, the hinge 208 is buckled, so that the insertion rod 209 on the hinge 208 is inserted into the interface. Finally, the screw is screwed into the threaded hole 202 to complete the installation. After the installation is completed, the blade 109 is opened to allow the ventilation pipe 1 to ventilate. In the event of a fire accident, the smoke is discharged from the ventilation pipe 1. When the smoke is discharged to the air deflector 101, the discharge of the smoke can be accelerated. When the smoke continues to be discharged forward, the impurities in the smoke are filtered by the filter plate 214. When the temperature reaches a certain level, the temperature sensor 211 is triggered. The temperature sensor 211 triggers the start of the motor 103. When the motor 103 starts, it drives the crown gear 106 to rotate. When the crown gear 106 rotates, it drives the gear 107 to rotate. When the gear 107 rotates, the blade 109 is closed. After the fire is over, the filter plate 214 can be pulled out from the ventilation pipe 1 to replace the filter plate 214.
