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必需有定位及密封措施。風管連接的兩平而應平直，不能錯位和扭曲。
When the general spiral air duct is connected, the incision should be firmly secured. The four corners of the rectangular duct must be positioned and sealed. The air duct should be two straight and straight, and must not be misplaced or twisted.
下面介紹幾種常見方法：
The following are several common methods:
一、插條式連接
One, bar 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 cuttings are connected to the rectangular air duct to connect different forms of inserts into the two ends of the duct.
二、抱箍式連接
Two, 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較后用螺栓穿在耳環(huán)中固定擰緊。
The two ends of each section of the hoop are rolled into a drum, and the end is reduced to a small mouth. The small opening is inserted in the direction of air flow in the direction of the air flow. The steel drums of the two pipe ends are tightly connected and the bolts are fastened and tightened in the earrings with the bolts.
三、軟管式連接.
Three. 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(cè)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 the spiral air duct with components (such as the side outlet of the diffuser, etc.). The two ends of the flexible arm are sleeved outside the connecting pipe.
四、管插接式連接
Four, tube connected connection
螺旋風管的安裝顯著地減少了管與管之間的連接點，使管件結(jié)合部的泄漏減少到較低程度，典型的螺旋風管長度是3~6m，而典型的矩形風管的長度只有1~1.5m；且連接兩個螺旋風管只需一個管接件，而傳統(tǒng)的矩形風管的連接則常常需要一個完全獨立的雙法蘭系統(tǒng)。
The installation of the spiral duct significantly reduces the connection point between the tube and the tube, reducing the leakage of the joint of the pipe to a lower degree. The typical length of the spiral duct is 3~6m, and the typical rectangular duct has a length of only 1~1.5m; and the connection of the two spiral pipes is only one tube connector, while the traditional rectangular wind pipe is often connected. A completely independent double flanged system is needed.
⑵標準化產(chǎn)品。
(2) standardization of products.
螺旋圓風管的配件（管件和接頭）的生產(chǎn)已高度自動化、系統(tǒng)化，并具有工業(yè)化的質(zhì)量控制。
The production of fittings (fittings and fittings) of spiral air ducts has been highly automated and systematic, and has industrialized quality control.
⑶安裝費用低。
(3) the cost of installation is low.
圓形風管系統(tǒng)的安裝時間只有相類似的矩形管道的1/3。
The installation time of the circular duct system is only 1/3 similar to that of the rectangular pipe.
⑷通常只需較小的安裝空間。
Usually only a small installation space is required.
在不增加任何壓降的情況下，相同的安裝空間內(nèi)直徑為200mm的圓形管道可取代250×150mm的矩形管道。
Without increasing any pressure drop, a circular pipe with a diameter of 200mm can be replaced by a 250 * 150mm rectangular pipe in the same installation space.
