Fire damper safety different environmental impact factors

Release Time：2021-07-21

Fire dampers, in daily life, few people understand this knowledge, unless he is a professional designer, or a professional installation engineer, many people think that usually fire dampers do not need to move, perhaps decades will not move once, thus ignoring his importance, but from the professional design concept, fire dampers play a considerable role in architecture, he is closely related to people's lives and property. In order to ensure the parts that only move once in decades, I believe everyone will also think of the fire damper. We must choose products with mechanical properties and product quality, and what are the inspection methods for fire dampers.
(1) Reliable because it is set at the specified position, its structure must ensure that the wind of the unclosed fire falls and falls.
(2) Set up an inspection port near the valve, and the position should be set up in a part that is easy to check.
(3) It does not rust, and the rotation shaft is running well at low rotation.
(4) The vulva leaves are not deformed and can be completely closed.
(5) The transmission fire damper device can be reliably started according to the signal of fuse melting or smoke detector.
When we have a good fire damper equipment, we sometimes find that its smoke exhaust effect is not very practical, but the quality of the goods is no problem. In that case, what is the reason for this situation? The main reasons are as follows:.
First of all, the direction of the fire valve device is improper.
Considering the effect scale of smoke exhaust, the smoke exhaust window may be installed in the direction as close to the upper part of the house wall as possible. The fire damper can be installed in the middle and even the lower part of the partition wall. The distance from the top is relatively large, which is extremely beneficial to natural smoke exhaust.
② Furthermore, the window opening area of the fire damper does not conform to the standard, and there are clear rules for selecting the window opening area of the natural smoke exhaust direction. However, because some scheme personnel did not stop careful calculation according to the standard requirements, the area of the movable window may be calculated within the smoke exhaust window area, so that the smoke exhaust window area of some fortifications did not meet the standard requirements, which directly reflects the smoke exhaust effect.
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.
