Fire valve use common questions how to choose

Release Time：2021-07-21

In the pipeline planning of ventilation and air conditioning systems, although it is calculated, if the working conditions of practical projects change, it is required to dispatch the air volume of each part of the system through fire dampers and valves, carry out system debugging, fix the opening of the valves and allocate them reasonably to meet the planning requirements. As an indispensable fire fighting facility in engineering construction equipment, fire dampers can effectively prevent fire extension, it plays a vital role in promoting a safe environment.
Fire valve in the use of the process will have what common questions.
1 fire damper, fire control room to send, return air pipe in its through the wall without fire damper, set up fire damper equipment is to ensure the fire safety of the fire control room, but in the construction process will find some engineering planning drawings on the fire control room to send, return air pipe in its through the wall without fire damper.
2. The control of smoke prevention and smoke exhaust equipment by fire control equipment is not perfect.
3, pipe network gas rescue system without pneumatic fire damper.
4. There is no remote control when the air supply and smoke exhaust duct is used together. When some basements are built and fire dampers are used in the parking lot, it is found that the stop valve in front of the blower and smoke exhaust can only be manually operated on site and cannot realize remote control of the control room. In case of fire, people need to go to the site to close the stop valve in front of the blower, which will directly affect the smoke exhaust system.
How to select the fire valve.
Fire dampers are suitable for ventilation and air conditioning systems. Except for fire dampers for kitchen fume exhaust systems in public buildings, which have an operating temperature of 150 ℃, fire dampers are generally used for ventilation and air conditioning systems. Fire dampers are suitable for pipelines of ventilation, air conditioning or smoke exhaust systems. When selecting valves, attention should be paid to the function of valves, such as normally open or normally closed, actively closed open, manually closed open, manually reset and signal output, long-distance control and other requirements.
The valve body blade shall be steel plate with a thickness of 2~6mm. The valve body shall be made of non-combustible materials. The rolling parts shall be made of corrosion-resistant metal materials and be sensitive to rolling. The thickness of the valve shell shall not be less than 2mm. The melting parts shall conform to the approved specifications of the fire protection part.
Shandong Xingheng Environmental Technology Group Co., Ltd. is located in Luquantun Development Zone, Dezhou, Shandong, the hometown of FRP in China. The company has Grade II qualification for fire protection facilities engineering, Grade II qualification for construction mechanical and electrical installation engineering, Grade II qualification for environmental protection engineering, and safety production license. It is the first in the industry to pass ISO9001 quality management system certification, ISO14001 environmental management system certification, OHSAS18001 occupational health management system certification, and an axial fan invention patent, A fan utility model patent, environmental assessment, safety assessment, three simultaneous and other procedures are complete.
