　　1、风管成品应按系统编号码放整齐，搬运、装卸应轻拿轻放，防止损坏。

　　1. The finished products of air duct should be placed neatly according to the system number. Handling and handling should be handled lightly to prevent damage.

　　2、交叉作业较多加工程，严禁以安装完的风管作为支、吊、托架，不允许将其它 支、吊架焊在或挂在风管法兰和风管支、吊架上，更不能在风管上站人。

　　2. There are many cross-working processes. It is strictly forbidden to use installed air ducts as supports, hangers and brackets. It is not allowed to weld or hang other branches and hangers on air duct flanges, air duct supports and hangers, let alone stand on air ducts.

　　a.本工程风管系统主要有多叶调节阀、蝶阀、防火防排烟阀等各类风阀，在安装前应检查框架结构是否牢固，调节、制动、定位等装置应准确灵活。

　　A. The main air duct systems in this project are multi-leaf regulating valves, butterfly valves, fire prevention and smoke exhaust valves and other kinds of air valves. Before installation, it is necessary to check whether the frame structure is firm, and the adjusting, braking and positioning devices should be accurate and flexible.

　　b.根据风管法兰螺桂孔尺寸在风阀的法兰上打孔。

　　B. Punch holes on the flange of the air valve according to the size of the air pipe flange screw.

　　c.风阀的安装与风管相同，在安装时只要把阀的法兰与风管或设备上的法兰对正，加上密封垫上紧螺丝，使其连接牢固及紧密即可。

　　C. The installation of the air valve is the same as that of the air duct. During installation, the flange of the valve should be aligned with the flange of the air duct or equipment, and the tightening screw on the sealing gasket should be added to make the connection firm and tight.

　　d.应注意风阀安装部位，使阀件的操纵位置便于操作。

　　D. Attention should be paid to the installation position of the air valve so as to facilitate the operation of the valve parts.

　　e.安装时要注意风阀的气流方向，不得装反，应按风阀外壳标注的方向安装。

　　E. Attention should be paid to the airflow direction of the air valve during installation. It should not be reversed. It should be installed in the direction marked by the air valve shell.

　　f.防火阀是通风系统的装置，要保证在火灾时起到关闭和停机的作用。防火阀有水平、垂直、左式和右式之分，定货和安装时应根据设计要求进行，防火阀有水平、垂直、左式和右式之分，定货和安装时应根据设计要求进行，防止弄错。为防止防火阀易熔片脱落，易熔片应在系统安装后，系统试运转之前再行安装。

　　F. Fire-proof valve is the safety device of ventilation system. It is necessary to ensure that it can shut down and shut down in case of fire. Fire valves are divided into horizontal, vertical, left and right types. Order and installation should be carried out according to the design requirements. Fire valves can be divided into horizontal, vertical, left and right types. Order and installation should be carried out according to the design requirements to prevent mistakes. In order to prevent the fusible sheet from falling off, the fusible sheet should be installed after the system is installed and before the system is commissioned.

　　g.为了方便更换和检查防火阀的易熔片，还应根据设计，在靠近防火阀的风管段上设置检查门。

　　G. In order to replace and inspect the fusible sheet of the fire valve conveniently, an inspection door should be set on the air duct section near the fire valve according to the design.
