Fire damper market development demand promotes standardization

What is the role of fire dampers in the end? In fact, many people do not know. As an essential fire-fighting installation for engineering construction and installation, it plays an important role in preventing the spread of fire. It can automatically shut down when the gas temperature in the pipeline reaches 70°C in the event of a fire, and it can meet the fire resistance within a certain period of time. Stability and fire-resistance require that the valve act as a smoke-suppressing and fire-retardant valve to prevent the fire from spreading to other places through the ventilation ducts, which can effectively prevent the spread of fire.

However, because the fire damper was installed in the middle of the ventilation duct, it was not visible at ordinary times and many people ignored its role. In 2009, a total of 363 fire-fighting products were sampled across the country's public security and fire departments, and 287 were qualified for inspection. The average sampling rate was 79.06%. The spot check of fire dampers and smoke dampers was a serious problem. A total of 49 samples were spot-checked. 15 samples passed the inspection, and the sampling pass rate was only 30.61%. With such a low pass rate, how does a fire damper function normally, and what problems exist in the fire damper market in China? In this regard, the HC Firefighting Network connected Beijing Guangjian Zhenye Air Conditioning Equipment Co., Ltd. Mr. Chen Youshan.

For the fake and shoddy phenomenon in the market of fire dampers, Mr. Chen believes that this is mainly because manufacturers do not strictly follow the national standards for production. In addition, some manufacturers cut corners during production, such as using some tailings to produce, these are caused by fire dampers The reason for the pass.

Counterfeit goods affect the normal function of the fire damper, and the consequences are serious, but the correct installation of the fire damper will also affect the normal use of the fire damper. Mr. Chen mentioned that the current production and installation of fire dampers are all different. The technology of the installed engineering teams is uneven, and a considerable number of installation team units do not have professional skills. They often use some Forced means, this will lead to product deformation, the loss of function of the product or weakened.

When talking about China's current fire damper market, Mr. Chen mentioned that there are many manufacturers of fire dampers in China, and there are more than 100 in Beijing alone. However, these manufacturers are small enterprises, and there are no large enterprises that can play a leading role. The disorderly competition in the market is more serious. China's fire dampers have a unified standard GB15930-2007 "Fire Ventilation Valves for Building Ventilation and Exhaust Smoke Systems", but Mr. Chen believes that this standard is not enough for refinement. He mentioned that the fire damper standard only specifies some rough standards, but there is no uniform standard for the specific component standards, such as the thickness of the valve body. Mr. Chen mentioned that due to the fire damper standards currently in force in our country, there are no more detailed standards for the production and installation of fire dampers. “At present, most manufacturers in China are generally producing according to the bill of lading of the project, which leads to the Passive, only in accordance with the requirements of the project to produce products so that enterprises can not mass production, which to a large extent impeded the rapid development of the company."

In addition, Mr. Chen also pointed out that because the fire damper is not the main product of the ventilation system, it is only installed in the pipeline, so it is often overlooked by the relevant departments. He hoped that the relevant departments can pay attention to the development of the fire damper market, improve the relevant standards for fire dampers, refine the standards, and unify the technology. This can more effectively promote the healthy development of the fire damper market in China, and can also reduce to some extent The emergence of fake and shoddy products.
