Smoke exhaust fire valve is an important equipment used to prevent the spread of fire in a building, its main function is to quickly close the smoke exhaust ventilation system in the event of a fire, and prevent the flame and smoke from spreading through the ventilation pipe. The installation position of the smoke exhaust fire valve is usually set between the smoke exhaust channel, air duct and fire protection zone of the building, which plays the role of automatically closing protection in the case of fire.

First, the use of smoke exhaust fire valve:

1. Prevent the spread of fire: In the event of a fire, the smoke exhaust fire valve can quickly close the ventilation system and prevent the spread of fire.

2. Protect the safety of personnel life and property: The function of the smoke exhaust fire valve is to minimize the loss of fire and protect the safety of personnel life and property.

3. Maintain the building structure: prevent the smoke and high temperature of the fire from causing damage to the building structure and extend the service life of the building.

4. Comply with the requirements of laws and regulations: the smoke exhaust fire valve is a part of the building fire protection equipment and must comply with the provisions of relevant laws and regulations.

Second, precautions for the installation of smoke exhaust fire valve:

1. Selection of installation position: The installation position of the smoke exhaust fire valve should be in the appropriate position of the ventilation duct or fire separation area to ensure that it can be closed in time when the fire occurs.

2. Installation height requirements: The installation height of the smoke exhaust fire valve should meet the relevant regulations to ensure its normal opening and closing.

3. Reliability of the equipment: Select a smoke exhaust fire valve with reliable quality, and install it correctly according to the requirements of the manufacturer.

4. Installation requirements: The installation of the smoke exhaust fire valve should meet the relevant fire protection design requirements to avoid failure caused by improper installation.

5. Regular maintenance and inspection: Regular maintenance and inspection of the smoke exhaust fire valve to ensure its normal operation and timely detection of problems.

6. Fire protection linkage: The smoke exhaust fire valve can be linked with the fire protection system to achieve better fire protection effect.

7. Maintain smooth ventilation: The normal use of smoke exhaust fire valve should keep the ventilation system smooth to avoid affecting the ventilation effect.

8. Pay attention to the smoke exhaust effect: the selection and installation of the smoke exhaust fire valve should consider the smoke exhaust effect to ensure that the smoke emission is smooth during the fire.

In short, the smoke exhaust fire valve is a very important fire fighting equipment in the building, which must be installed in strict accordance with the relevant requirements to ensure its normal operation, and regular maintenance checks to ensure that it can play its due role in the event of a fire and effectively protect the safety of personnel and property.
