In daily life, the fire control valve is an essential part. What are the advantages that attract us? What is the main function of the fire control valve? The following is a brief introduction to the advantages and main functions of the fire control valve.
The fire control valve device is usually open on the air supply and return pipelines of ventilation and air conditioning systems. When the gas temperature in the pipeline reaches 70 ℃ in case of fire, the fusible sheet will fuse, and the valve will automatically close under the effect of torsion spring force. The valve that can meet the requirements of fire stability and fire integrity within a certain time and has smoke isolation and fire retardant effect will output a closing signal when the valve is closed, and can also be interlocked with fan equipment.
The advantages of fire control valve: 1, low air leakage, good airtight function, 2, strong anti-corrosion function, long service life, 3, flexible actuator drive, fire damper response, accurate interlock signal, the main functions of fire control valve: 1, manual open, manual reset closed, 2, can output valve open signal and interlock control signal, the general device of the fire control valve needs to adjust the air volume of the ventilation and air conditioning system on the air duct, which is suitable for horizontal or straight air flow.
At present, fire prevention and theft prevention is the top priority of residents' life. Therefore, the application of smoke exhaust fire damper is more and more widespread. However, there are many shortcomings and deficiencies in the detailed construction project of smoke exhaust fire damper. The following is a detailed analysis:.
Disadvantage 1: The air inlet pipe and air outlet pipe of the fire control room are not equipped with fire dampers in the local area where they pass through the wall surface. In the construction review process, it is shown that the air supply pipe and air outlet pipe of the fire control room on some engineering planning manuscript paper do not have fire dampers in the local area where they pass through the wall surface. Fire dampers are contrary to some relevant regulations. The goal of setting fire prevention valves is to ensure the fire safety of fire control room.
Disadvantage 2: The fire control is equipped with the control of smoke prevention and smoke emission equipment, which is not fully effective. According to relevant regulations, in the future, the air outlet of air conditioning in some directions must be stopped, the electric fire prevention valve must be blocked, and its feedback information must be accepted. At the same time, the smoke prevention and smoke emission fans and smoke exhaust valves in some directions must be opened, and its feedback information must be accepted.
Kitchen fume will affect the health of many people. Many people often use smoke exhaust fire dampers to reduce the damage of fume. Before the equipment smoke exhaust fire dampers, it is necessary to check whether each mechanism of the air outlet is in good condition. The air outlet is made of non-combustible materials. The rolling parts should be made of corrosion-resistant gold fire dampers and roll sensitively.
At present, the fuel of kitchen stoves in hotels, restaurants and restaurants is mainly gas or fuel oil. Once the stove or fuel transportation pipeline leaks, a fire will occur in case of open fire, and oil scale will accumulate in the smoke exhaust hood and smoke exhaust pipeline. In case of fire caused by open fire, the smoke exhaust hood and air duct will gradually accumulate oil scale due to the influence of oil smoke. When the oil scale in the smoke hood and air duct meets open fire, it is easy to burn, and through the fan, air duct and other ways to extend and cause a fire.
With the advance of public awareness of fire protection and the need to maintain the safety of citizens' lives and property, the prevention of commercial kitchen fires has attracted the attention of relevant departments. It is necessary to strengthen the construction of fire safety planning, strengthen the control and monitoring of fuel, regularly clean pipelines, avoid excessive oil temperature and equip rescue equipment.
