How to distinguish the different types of tuyere adjusting plate is installed in the slot of the tuyere adjusting plate, which is used to adjust the air volume.

　　百葉是一個長葉片的組合，圍繞一個軸旋轉(zhuǎn)。當葉片連接到飛機上時，葉片之間的空間很小，能夠通過的空氣量也很小。當葉片以斜角旋轉(zhuǎn)時，葉片與能夠通過的大量空氣之間存在較大的間隙。當葉片垂直于葉框時，間隙間隔越大，風量越大，因此可以通過百葉調(diào)節(jié)人室的風量?；顒影偃~調(diào)節(jié)垂直送風方向。

　　A louver is a combination of long blades that rotate around an axis. When the blades are connected to the aircraft, the space between the blades is very small, and the amount of air that can pass through them is also very small. When the blade rotates at an oblique angle, there is a large gap between the blade and the large amount of air that can pass through it. When the blade is perpendicular to the leaf frame, the larger the gap is, the larger the air volume is. Therefore, the air volume in the room can be adjusted by louvers. The movable louvers adjust the direction of vertical air supply.

　　單層百葉是只有一層百葉的風口。單層百葉風口結(jié)構(gòu)簡單，制造方便，但氣流衰減較慢，適用于功能范圍較大的房間集中送風。旋轉(zhuǎn)百葉作為鼓風機，由于導葉可調(diào)，鼓風機可以在垂直方向上調(diào)節(jié)送風方向。

　　A single-layer louver is a tuyere with only one layer of louvers. The single-layer louver tuyere is simple in structure and easy to manufacture, but its airflow attenuation is slow. It is suitable for centralized air supply in rooms with large function range. Rotary louvers are used as blowers. Because the guide vanes are adjustable, the blower can adjust the direction of air supply in the vertical direction.

　　雙百葉風口是有兩個百葉的風口。雙百葉不僅可以調(diào)節(jié)風量，還可以調(diào)節(jié)垂直和水平送風方向。百葉可以垂直安裝或水平安裝，也可以在處理的空氣量較大時平行安裝。

　　Double louver tuyere has two louver tuyeres. Double louvers can not only adjust the air volume, but also adjust the vertical and horizontal direction of air supply. The louvers can be installed vertically or horizontally, or in parallel when the air volume is large.

　　三層風口是一種具有三層風口的風口。三層百葉風口結(jié)構(gòu)復雜，生產(chǎn)不方便。

　　The three-layer tuyere is a kind of tuyere with three-layer tuyere. The structure of the three-layer louver tuyere is complex and the production is inconvenient.

　　白口鑄鐵加工技術(shù)含量相對較高。在許多白口鑄鐵加工工作中，對工人的技術(shù)要求極其嚴格，不僅為了工人的，而且為了更好地加工好白口鑄鐵產(chǎn)品。下面，為您介紹一下我們白鐵加工工人操作的技術(shù)要求。

　　White cast iron processing technology content is relatively high. In many white cast iron processing work, the technical requirements for workers are extremely strict, not only for the safety of workers, but also for better processing of white cast iron products. Next, I'd like to introduce our technical requirements for the safe operation of white iron workers.

　　操作錫機時應注意以下四點:

　　The following four points should be paid attention to when operating tin machine:

　　(1)使用白鐵加工壓機時不要用力推鐵板。壓力應是咬下的部分。手應距壓力輪20毫米以上。

　　(1) Do not push the iron plate hard when using white iron to process the press. Stress should be the first part of the bite. The hand should be more than 20 mm away from the pressure wheel.

　　(2)開車前用咬口機咬右邊的罐頭。驅(qū)動時工件應保持平穩(wěn)，手指不應放在咬入機的軌道上。

　　(2) Bite the cans on the right side with a biter before driving. When driving, the workpiece should be kept stable and the finger should not be placed on the track of the biting machine.

　　(2)滾輪的齒輪必須加裝防護罩。使用時應留有兩個壓輥的間隙，并在進給處加擋板。

　　(2) The gear of the roller must be equipped with a protective cover. When using, there should be two clearances between the rollers and a safety baffle should be added at the feeding point.

　　(4)使用白鐵切割機，刀架上不得放置刀具等物品。調(diào)整鐵板時，腳不應放在踏板上。切割時，不要將手伸進壓盤的縫隙中。

　　(4) Using white iron cutting machine, cutting tools and other items must not be placed on the tool holder. When adjusting the iron plate, the foot should not be placed on the pedal. When cutting, do not put your hand into the gap of the pressure plate.
