螺旋通风管道有几种链接方式？
通风管道中的风管制作与安装所用板材、型材以及其他主要成品材料，应符合设计及相关产品现行标准的规定，并应用出厂检验合格证明，材料进场时应按现行有关标准进行验收。
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.
通风管道是为了使空气流通，降低有害气体浓度的一种市政基础设施。通风管，风管制作与安装所用板材、型材以及其他主要成品材料，应符合设计及相关产品现行标准的规定，并应用出厂检验合格证明，材料进场时应按现行有关标准进行验收。通风管道按材质分：一般有：钢板风管（普通钢板）、镀锌板（白铁）风管、不锈钢通风管、玻璃钢通风管、塑料通风管、复合材料通风管、彩钢夹心保温板通风管、双面铝箔保温通风管、单面彩钢保温风管、涂胶布通风管（如矿用风筒）、矿用塑料通风管等；
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.
一般的螺旋风管在连接时候,切口处应严密牢固矩形风管四角要有定位及密封措施。风管连接的两平而应平直，不能错位和扭曲。螺旋风管在链接时候通常有几种方式？
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、插条式连接
I. Plug Connection
插条式连接于矩形风管连接将不同形式的插条插入风管两端。
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、抱箍式连接
2. Hoop connection
抱箍式连接每一管段的两端轧制成鼓筋,并使及一端缩为小口，安装时按气流方向把小口插入大口,外面用钢制拖箍将两个管端的鼓筋抱紧连接用螺栓穿在耳环中固定拧紧。
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、软管式连接.
3. Hose connection.
软管式连接主要用于螺旋风管与部件（如散流器静压箱侧送风口等）的相连安装时,软臂两端套在连接管外。
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、管插接式连接
IV. Pipe-and-socket Connection
插接式连接主要用于矩形或圆形风管连接,先制作连接管然后插入两侧风管再用自攻螺钉或拉柳钉将及紧密固定,用特制软卡把软管箍紧。螺旋风管经济，在同等管径下，螺旋风管加工的板厚能够降低10%—15%。其能够降低造价，并且在吊装时，效率要比矩形风管的高一倍左右。在同等板厚和管径下，螺旋风管的强度更高。在同等截面下，螺旋风管的结构张力更加合理，刚性更好，因此能够大大降低噪音和震动。
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.
