風閥的特點：對開多葉風閥接管尺寸與通風管道規范化規定的矩形風管尺寸相同;風閥葉片為對開式和順開式，通風、空氣調節、空氣凈化系統中作為調節閥;通過試驗測定，風閥的氣密性好，其相對漏風量在5%左右，調節性能好。

　　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.

　　風閥的結構應牢固，調節靈活，定位準確、可靠，并應標明風閥的啟閉方向及調節角度。

　　The structure of the air valve shall be firm, flexible, accurate and reliable, and shall indicate the opening and closing direction of the air valve and the angle of adjustment.

　　風閥，顧名思義，即風量調節閥,風閥是工業廠房民用建筑的通風、空氣調節及空氣凈化工程中不可缺少的空調末端配件，一般用在空調，通風系統管道中，用來調節支管的風量，也可用于新風與回風的混合調節。

　　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.

　　蝶閥閥板規格不得比短管內徑小于3mm，閥軸用圓鋼一端銼成方形，而頂端車成圓形螺紋頭，將另一端做成扁形。手柄用扁鋼烴成s形，打眼時注意方向。

　　The butterfly valve plate than the short diameter specification shall not be less than 3mm, a square round one end of the valve shaft and the top car file, round thread head, the other end is made of flat. Handle with the flat of hydrocarbon S shaped drill, attention direction.

　　止擋板要放出兩端彎腳，煨成90度后，再開長槽銼光。裝配時先將墊板固定在短管上，再把軸套在短管內，并用螺栓上緊閥板，后將手柄裝好。閥板與殼體的間隙應均勻，不得碰擦，試驗靈活后，標明開、閉方向。拉鏈式蝶閥的鏈條應按其位置高度配置。

　　The stopper plate to release two curved legs, simmer 90 degrees, then smooth long groove. When assembling, the shim plate is fixed on the short tube, then the sleeve is in the short pipe, and the valve plate is tightened with a bolt, and finally the handle is installed. The valve plate and the clearance of the shell should be uniform and should not be touched and rubbed. After the test is flexible, mark the direction of opening and closing. The chain of the zipper butterfly valve shall be arranged according to its position and height.

　　插扳閥(包括斜插板閥)的殼體應嚴密，殼體內壁應作防腐處理。插板應平整，套閘板的上、下兩塊悶板與墊板的規格要相同。斜插板閥的上下兩塊悶板開孔要相互錯開，但螺孔要對正。

　　Plug valve (including inclined plate valve) shell should be tight, the shell wall should be anti-corrosion treatment. The flashboard shall be flat, and the top and bottom two blocks of the ram plate shall be of the same specifications as the backing plate. Oblique plate valve of the upper and lower two block plate opening to stagger each other, but the screw must be right.

　　悶板開孔時，斜插板閥按45度設置，形狀為橢圓形。將兩塊悶板先點焊在管端上，并組合檢查管子是否成直線，找正后方可焊接。裝配時，將兩塊悶板中間墊好墊板，放入插板閥，上緊螺栓，要求啟閉應靈活，并應由可靠的插板固定裝置。

　　When the boring plate is opened, the inclined flashboard valve is set at 45 degrees, and the shape is elliptical. First, the two block plate is welded to the end of the pipe, and check whether the pipe is in a straight line. When assembling, place the two shim plates in the middle and put them into the flashboard valve and tighten the bolts. The opening and closing shall be flexible, and the reliable inserting plate fixing device shall be adopted.
