发布时间:2017/09/14

  风阀的特点:对开多叶风阀接管尺寸与全国通风管道规范化规定的矩形风管尺寸相同;风阀叶片为对开式和顺开式,通风、空气调节、空气净化系统中作为调节阀;通过试验测定,风阀的气密性好,其相对漏风量在5%左右,调节性能好。

  The characteristics of the air valve: Multiblade wind valve and the vent pipe size regulate the rectangular duct; air valve leaves open the split rolls, ventilation, air conditioning and air purification system as a control valve; by testing, air tightness of the air valve, the relative amount of air leakage in 5%, good regulating performance.

  风阀,顾名思义,即风量调节阀,风阀是工业厂房民用建筑的通风、空气调节及空气净化工程中不可缺少的中央空调末端配件,一般用在空调,通风系统管道中,用来调节支管的风量,也可用于新风与回风的混合调节。

  As the name implies, namely air valve, air flow control valve, air valve is the central air conditioning terminal fittings ventilation and air conditioning and air purification of civil building engineering in an industrial plant, commonly used in air conditioning, ventilation pipe system, used to adjust the tube of the air flow, can also be used for mixing of fresh air and return air conditioning。

  1。强度试验时,试验压力为公称压力的1。5倍,持续时间不少于5min,阀门的壳体、填料应无渗漏。

  1. strength test, the test pressure is 1.5 times the nominal pressure, duration of not less than 5min, the valve shell, filler should be no leakage.

  2.阀门的安装位置、高度、进出口方向必须符合符合口方向 ;设计要求,连接应牢固紧密。

  2. valve installation position, height, import and export direction must comply with the direction of the mouth; design requirements, the connection should be solid and tight.

  3.严密性试验时,试验压力为公称压力的1.1倍;试验压力在试验持续的时间内应保持不变,时间应符合表2的规定,以阀瓣密封面无渗漏为合格。

  3。 tight test, the test pressure is 1。1 times the nominal pressure; test pressure in the duration of the test should remain unchanged, the time should comply with table 2, to the surface of the valve sealing surface leakage is qualified。

  4.阀门可用各种形式的端部与管路连接。其中最主要的连接方式有螺纹、法兰及焊接连接。法兰连接时,若温度超过350℃时,由于螺栓、法兰和垫片蠕变松弛,应选择耐高温螺栓材料。

  4。 valves can be connected in various forms to the ends of the pipe。 The most important connections are threaded, flanged and welded connections。 If the temperature is more than 350 degrees when the flange is connected, because of the creep of bolts, flanges and gaskets, high temperature bolt material should be chosen。
