風(fēng)閥的特點：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;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。

　　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.

　　風(fēng)閥，顧名思義，即風(fēng)量調(diào)節(jié)閥,風(fēng)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)。

　　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.

　　一般濟(jì)南排煙罩用在空調(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)。

　　Generally, the smoke hood of Ji'nan is used in the air conditioning and ventilation system pipes to regulate the air flow of the branch pipe, and also can be used for the mixing regulation of fresh air and return air.

　　1.強(qiáng)度試驗時，試驗壓力為公稱壓力的1.5倍，持續(xù)時間不少于5min，閥門的殼體、填料應(yīng)無滲漏。

　　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.閥門的安裝位置、高度、進(jìn)出口方向必須符合符合口方向 ;設(shè)計要求，連接應(yīng)牢固緊密。

　　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.嚴(yán)密性試驗時，試驗壓力為公稱壓力的1.1倍;試驗壓力在試驗持續(xù)的時間內(nèi)應(yīng)保持不變，時間應(yīng)符合表2的規(guī)定，以閥瓣密封面無滲漏為合格。

　　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.閥門可用各種形式的端部與管路連接。其中主要的連接方式有螺紋、法蘭及焊接連接。法蘭連接時，若溫度超過350℃時，由于螺栓、法蘭和墊片蠕變松弛，應(yīng)選擇耐高溫螺栓材料。

　　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.
