　　1、風管成品應(yīng)按系統(tǒng)編號碼放整齊，搬運、裝卸應(yīng)輕拿輕放，防止損壞。

　　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、交叉作業(yè)較多加工程，嚴禁以安裝完的風管作為支、吊、托架，不允許將其它 支、吊架焊在或掛在風管法蘭和風管支、吊架上，更不能在風管上站人。

　　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.本工程風管系統(tǒng)主要有多葉調(diào)節(jié)閥、蝶閥、防火防排煙閥等各類風閥，在安裝前應(yīng)檢查框架結(jié)構(gòu)是否牢固，調(diào)節(jié)、制動、定位等裝置應(yīng)準確靈活。

　　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.根據(jù)風管法蘭螺桂孔尺寸在風閥的法蘭上打孔。

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

　　c.風閥的安裝與風管相同，在安裝時只要把閥的法蘭與風管或設(shè)備上的法蘭對正，加上密封墊上緊螺絲，使其連接牢固及緊密即可。

　　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.應(yīng)注意風閥安裝部位，使閥件的操縱位置便于操作。

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

　　e.安裝時要注意風閥的氣流方向，不得裝反，應(yīng)按風閥外殼標注的方向安裝。

　　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.防火閥是通風系統(tǒng)的裝置，要保證在火災(zāi)時起到關(guān)閉和停機的作用。防火閥有水平、垂直、左式和右式之分，定貨和安裝時應(yīng)根據(jù)設(shè)計要求進行，防火閥有水平、垂直、左式和右式之分，定貨和安裝時應(yīng)根據(jù)設(shè)計要求進行，防止弄錯。為防止防火閥易熔片脫落，易熔片應(yīng)在系統(tǒng)安裝后，系統(tǒng)試運轉(zhuǎn)之前再行安裝。

　　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.為了方便更換和檢查防火閥的易熔片，還應(yīng)根據(jù)設(shè)計，在靠近防火閥的風管段上設(shè)置檢查門。

　　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.
