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.

該風(fēng)量調(diào)節(jié)閥是工業(yè)廠房民用建筑的通風(fēng)、空氣調(diào)節(jié)及空氣凈化工程中不可缺少的空調(diào)末端配件，一般用在空調(diào)，通風(fēng)系統(tǒng)管道中，用來調(diào)節(jié)支管的風(fēng)量，也可用于新風(fēng)與回風(fēng)的混合調(diào)節(jié)。

The 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.

風(fēng)閥的特點(diǎn)：對開多葉風(fēng)閥接管尺寸與通風(fēng)管道規(guī)范化規(guī)定的矩形風(fēng)管尺寸相同.

The characteristics of the air valve: the opening of the multi blade wind valve is the same size as the rectangular pipe of the national ventilation duct

風(fēng)閥葉片為對開式和順開式，通風(fēng)、空氣調(diào)節(jié)、空氣凈化系統(tǒng)中作為調(diào)節(jié)閥；通過試驗(yàn)測定，風(fēng)閥的氣密性好，其相對漏風(fēng)量在5%左右，調(diào)節(jié)性能好。

Air valve blade for the open and open, ventilation, air conditioning, air purification system as a control valve; through the test, the air tightness of the air valve, and its relative air leakage in the amount of about 5%, good regulation performance.
