注意啦..螺旋风管的连接方式有这些

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必需有定位及密封措施。风管连接的两平而应平直，不能错位和扭曲。

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.

下面介绍几种常见方法：

The following are several common methods:

一、插条式连接

One, bar 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 cuttings are connected to the rectangular air duct to connect different forms of inserts into the two ends of the duct.

二、抱箍式连接

Two, 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较后用螺栓穿在耳环中固定拧紧。

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、软管式连接.

Three. 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 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、管插接式连接

Four, tube connected connection

螺旋风管的安装显著地减少了管与管之间的连接点，使管件结合部的泄漏减少到较低程度，典型的螺旋风管长度是3~6m，而典型的矩形风管的长度只有1~1.5m；且连接两个螺旋风管只需一个管接件，而传统的矩形风管的连接则常常需要一个完全独立的双法兰系统。

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标准化产品。

(2) standardization of products.

螺旋圆风管的配件（管件和接头）的生产已高度自动化、系统化，并具有工业化的质量控制。

The production of fittings (fittings and fittings) of spiral air ducts has been highly automated and systematic, and has industrialized quality control.

⑶安装费用低。

(3) the cost of installation is low.

圆形风管系统的安装时间只有相类似的矩形管道的1/3。

The installation time of the circular duct system is only 1/3 similar to that of the rectangular pipe.

⑷通常只需较小的安装空间。

Usually only a small installation space is required.

在不增加任何压降的情况下，相同的安装空间内直径为200mm的圆形管道可取代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.
