The fire valve is an important firefighting equipment to prevent the spread of flames and smoke.The installation principle is mainly based on the control and monitoring of airflow to ensure that the fire spreads effectively during the fire.The following is a detailed introduction to the principle of fire valve installation.
1. Working principle
The fire prevention valve is mainly composed of leaves, frameworks, rotation shafts, execution agencies, and control systems.When the fire occurs, the control system of the fire valve detects the fire signal and performs the movement of the institution, so that the leaves rotate on the shaft, close or adjust the valve port to prevent air flow from passing.At the same time, the fire prevention valve is usually equipped with a fuse. When the fire temperature reaches a certain value, the fuse is melted to make the execution mechanism move.
2. Installation location
The fire valve is usually installed on the air duct of the ventilation air conditioning system, playing the role of partitioning the fire source.Depending on different use places and needs, the fire valve can be installed in different locations.For example, in the smoke exhaust system, the fire valve is installed on the smoke exhaust pipe to prevent the spread of smoke; in the air -conditioning system, the fire valve is installed on the air supply pipe to prevent flames from spread through the air conditioning system through the air conditioning system.
The above is the introduction of the installation principle and installation location of the fire valve
