A successful 6 hour fire endurance test on our fire dampers
Both the standard and narrow blade profiles were successfully tested and were still maintaining full integrity after 6 hours when the test was discontinued.
In addition to fire exposure, our fire dampers have been tested for leakage at elevated temperature and various supplemental reliability tests.
Our fire dampers have been tested by the FAREAST Fire Research centre, These tests were conducted upon several dampers installed in both horizontal and vertical modes. All tests were successfully conducted for six hours of fire endurance measured against the standard time/temperature curve (see below). The furnace was controlled so that its mean temperature complied with the curve. The dampers were evaluated against the following criterion: IMO FTP Code, Annex 1, Part 3 and SOLAS 1974 as amended requires that there is no collapse of the specimen, no flaming on the unexposed surface and no loss of impermeability. These requirement were satisfied throughout the 6 hour duration of tests.


防火阀六小时成功耐火试验
标准型及窄型叶片都成功地通过了耐火试验 ,并且在六小时的耐火试验后仍能够保持其完整性 。
除了耐火试验外,我们的防火阀还在更高温度下通过了防漏试验以及各种附加可靠性试验。
我们的防火阀通过了远东防火研究中心的测试认证。这些试验是在水平及垂直安装下针对多种防火阀进行的。根据标准的 时间--温度曲线(见下图),所有测试都成功的通过了六小时防火耐久性试验。在试验过程中,对试验用火炉温度进行了精确 的控制, 使得其平均温度能够符合远东防火研究中心的测试要求。防火阀根据标准IMO FTP Code, Annex 1, Part 3 and SOLAS 1974 as amended进行评定,该标准要求:被测样品不得有塌陷、在非接触表面不得由烧痕,同时须保持其密封性。
在六小时的 试验过 程中, 我们的防火阀都完全符合这些要求。


  
           

Volume control damper
The Volume control damper are constructed of corrosion resistant,galvanised steel with brass or stainless steel bushes.Interconnecting linkages pivot on stainless steel(pins) to prevent the risk of seizure. It is rigid and efficient in the air volume control.Separate units maybe coupled together with additional linkage to form a face and by-pass mixing dampers.The additional linkage causes the blades of one damper to close as blades of one damper to close as blades of other damper are open.
Frames can be supplied using any of the standard frame members or multiple of different frame members thus allowing the most economical choice of damper frame.The Volume control damper can be easily installed on either horizontal or vertical position.
Availbility
The volume dampers are available in standard modules up to 1500mm vertical and 800mm horizontal dimensions. Sizes are available at increments of 50mm. Where larger sizes are required, multiple dampers sections are coupled together to operate in unison.Extended shaft for motorised drives, felt edge blades, damper position indicator and multi-modular units with alterate modules shut or open for use as mixing zone dampers. The Volume control damper can be supplied with motor mounting brackets for either electric or pneumatic actuation. Where required, dampers maybe fabricated of stainless steel or aluminium.


风量调节阀
风量调节阀采用防腐蚀镀锌钢制作,衬套为铜材或不锈钢。联接件可绕着不锈钢(销子)转动,从而可防止咬合危险的发生。
可以可靠且高效的进行空气流量控制。通过辅助联接件将各个独立的装置连接起来,构成一个平面式旁通混合气流调节器。
辅助联接件可使某个气流调节器叶片的叶片闭合,从而使得某个气流调节器叶片闭合而其它气流调节器叶片打开。
调节器架可采用任何标准框架构件或多种不同型号的框架构件制作,这样,使得气流调节器的架子具有最好的经济性。
风量调节阀在水平式或立式位置的安装极其方便。
现有产品
现有的大容量风量调节器为标准模块,外形尺寸可达纵向1500毫米和横向800毫米。该系列的现有产品以50毫米的尺寸增量依次加以区分。在需要更大的尺寸时,可将多个风量调节器耦联,共同安装于延长驱动轴上,可感到叶片边缘和风量调节器位置指示器的作用,并借助可调节多模块单元的开、闭路作用,控制混合区域风量调节器的节气效果。该大容量式控制放大器,还可配备电机安装所用支架,并可采取电气或气动方式进行驱动。在需要的情况下,风量调节器可采用不锈钢或铝材来制造。

Heavy duty shut-off damper
The Heavy duty shut-off damper are constructed of heavy gauge material and full welded at each corner of the frame.This make the damper very robust and able to withstand rough handing on site.Due to the robust blade construction,the damper can withstand high pressure fluctuation encountered in certain applications.
High quality/Reliability
The Heavy duty shut-off damper are constructed of high quality material. All moving parts are constructed of stainless steel to prevent seizure. This ensures that the damper are able to operate under the most adverse conditions.
Extremely low leakage
The Heavy duty shut-off damper are designed with safety of life and property in mind. Extreme low leakage means minimum spread of toxic smoke which is the main cause of death or damages in a fire.
Low air flow resistance
The Heavy duty shut-off damper has aerofoil blades which present very small resistance to airflow across it due to its aerodynamic design.
Easy maintenance/Easy installation/Modular design
The damper frame has prepunched holes for ease of installation on site. For installation in wall where sleeve is required the damper will be provided with sleeve and retaining angles for easy installation. As the damper is constructed of high quality material and moving parts are constructed of stainless steel there is virtually no maintenance required on the damper. The damper is made in modular panels which can be assembled easily on site into large damper


重型气流截止阀
重型气流截止阀采用较厚的材料制作,架子的各角通过完全焊接联接。这就使得气流调节器极其坚固并能够承受现场野蛮装卸。
由于其稳固的叶片结构,气流调节器可承受在某些应用情况下的较高的压力波动。
高的质量和可靠性
这种重载关断的风量调节器具有高质量的结构材料。全部的运动零部件都由不锈钢制成,以防止卡壳。这样就能确保风量调节器能在最为不利的条件下运行。
极低的泄漏量
这种重载关断风量调节器的设计,可保证产品更新换代在使用寿命内的安全,并达到用户放心的性能。极低的泄漏量,意味着作为火灾中死亡或伤害主因的有毒烟气散布量,能够达到最低值。
气流阻力小
这种重载关断风量调节器具有翼形叶片,由于这种翼形叶片按照空气动力学设计,因而可产生非常小的气流阻力。
易维修/易安装/模块化设计
风量调节器外框上有一些预加工孔,以方便现场安装。为了装在需要有套筒的墙上,风量调节器必须配有套筒并保持一定的角度,以方便安装。由于风量调节器以高质量材料制成,而且全部的运动零部件都由不锈钢制成,因此,风量调节器实际上无需进行维护保养。风量调节器由模块面板构成,这样就能在现场方便地进行大型风量调节器的装配了。
