螺旋通風管道有幾種鏈接方式？
通風管道中的風管制作與安裝所用板材、型材以及其他主要成品材料，應符合設計及相關產品現行標準的規定，并應用出廠檢驗合格證明，材料進場時應按現行有關標準進行驗收。
Plates, profiles and other major finished products used in the operation and installation of ventilation ducts shall conform to the provisions of the current national standards for design and related products, and shall be checked and accepted according to the current relevant national standards when materials enter the field with the application of the certificate of qualifications for factory inspection.
通風管道是為了使空氣流通，降低有害氣體濃度的一種市政基礎設施。通風管，風管制作與安裝所用板材、型材以及其他主要成品材料，應符合設計及相關產品現行標準的規定，并應用出廠檢驗合格證明，材料進場時應按現行有關標準進行驗收。通風管道按材質分：一般有：鋼板風管（普通鋼板）、鍍鋅板（白鐵）風管、不銹鋼通風管、玻璃鋼通風管、塑料通風管、復合材料通風管、彩鋼夾心保溫板通風管、雙面鋁箔保溫通風管、單面彩鋼保溫風管、涂膠布通風管（如礦用風筒）、礦用塑料通風管等；
Ventilation pipeline is a municipal infrastructure for air circulation and reducing the concentration of harmful gases. Ventilation pipes, sheets, profiles and other major finished materials used in the operation and installation of air ducts shall conform to the provisions of the current national standards for design and related products, and shall be inspected and accepted according to the current relevant national standards when materials enter the field. Ventilation pipes are classified according to material: steel plate air duct (common steel plate), galvanized sheet (white iron) air duct, stainless steel air duct, FRP air duct, plastic air duct, composite material air duct, color steel sandwich heat preservation board air duct, double-sided aluminum foil heat preservation air duct, single-sided color steel heat preservation air duct, rubber coated air duct (such as mine air duct), mine plastic air duct, etc.
一般的螺旋風管在連接時候,切口處應嚴密牢固矩形風管四角要有定位及密封措施。風管連接的兩平而應平直，不能錯位和扭曲。螺旋風管在鏈接時候通常有幾種方式？
Generally, when connecting spiral ducts, the incision should be tightly and firmly rectangular ducts with positioning and sealing measures at the four corners. The air duct connection should be flat and not distorted or distorted. How many ways do spiral ducts usually connect?
一、插條式連接
I. Plug Connection
插條式連接于矩形風管連接將不同形式的插條插入風管兩端。
The insert type is connected to the rectangular air duct connection and inserts different forms of inserts into both ends of the air duct.

二、抱箍式連接
2. Hoop connection
抱箍式連接每一管段的兩端軋制成鼓筋,并使及一端縮為小口，安裝時按氣流方向把小口插入大口,外面用鋼制拖箍將兩個管端的鼓筋抱緊連接用螺栓穿在耳環中固定擰緊。
The two ends of each pipe segment are rolled into drum bars, and one end is shrunk into a small opening. When installed, the small opening is inserted into the big opening according to the direction of airflow. The drum bars at the two ends are tightly connected by steel tow hoops and fixed and tightened by bolts in the earrings.
三、軟管式連接.
3. Hose connection.
軟管式連接主要用于螺旋風管與部件（如散流器靜壓箱側送風口等）的相連安裝時,軟臂兩端套在連接管外。
The hose connection is mainly used for connecting spiral air duct with components (such as the side air outlet of the static pressure box of the diffuser), and the two ends of the soft arm are sleeved outside the connecting tube.
四、管插接式連接
IV. Pipe-and-socket Connection
插接式連接主要用于矩形或圓形風管連接,先制作連接管然后插入兩側風管再用自攻螺釘或拉柳釘將及緊密固定,用特制軟卡把軟管箍緊。螺旋風管經濟，在同等管徑下，螺旋風管加工的板厚能夠降低10%—15%。其能夠降低造價，并且在吊裝時，效率要比矩形風管的高一倍左右。在同等板厚和管徑下，螺旋風管的強度更高。在同等截面下，螺旋風管的結構張力更加合理，剛性更好，因此能夠大大降低噪音和震動。
Plug-in connection is mainly used for rectangular or circular air duct connection. Firstly, the connecting pipe is made, then inserted into both sides of the air duct, then fixed tightly with self-tapping screw or pulling willow nail, and the hose is tightened with special soft clamp. The helical duct is economical. Under the same diameter, the thickness of the plate processed by the helical duct can be reduced by 10%-15%. The utility model can reduce the cost and is about twice as efficient as the rectangular air duct in hoisting. Under the same thickness and diameter, the strength of spiral duct is higher. Under the same cross-section, the structural tension of the spiral duct is more reasonable and the rigidity is better, so the noise and vibration can be greatly reduced.
