通風(fēng)管道是工業(yè)與民用建筑的通風(fēng)與空調(diào)工程用金屬或非金屬管道，是為了使空氣流通，下降有害氣體濃度的一種基礎(chǔ)設(shè)施。通風(fēng)管道廠家在風(fēng)管制作與裝置過程中，所用板材、型材以及其他首要制品材料，應(yīng)符合規(guī)劃及相關(guān)產(chǎn)品現(xiàn)行標(biāo)準(zhǔn)的規(guī)矩，并使用出廠查驗(yàn)合格證明，材料進(jìn)場時(shí)應(yīng)按現(xiàn)行有關(guān)標(biāo)準(zhǔn)進(jìn)行查驗(yàn)。

Ventilation pipes are metal or non-metal pipes used in ventilation and air conditioning engineering of industrial and civil buildings. They are an infrastructure for air circulation and reducing the concentration of harmful gases. In the process of air-conditioning operation and installation, the materials used by ventilation pipeline manufacturers, such as plates, profiles and other primary products, shall conform to the regulations of the current national standards for planning and related products, and shall use the certificate of qualifications for factory inspection. The materials shall be inspected in accordance with the relevant national standards in force when entering the field.

一、風(fēng)管法蘭聯(lián)接

I. Flange connection of air duct

1、法蘭密封墊料。選用不透氣、不產(chǎn)塵、彈性好的材料，法蘭墊料應(yīng)盡量削減接頭，接頭方法選用階梯形或企口形，接頭處應(yīng)涂密封膠。法蘭之間的墊料應(yīng)符合規(guī)劃要求。

1. Flange gasket. Choose materials that are impermeable, dustproof and elastic. Flange gaskets should reduce joints as much as possible. Joint methods should be ladder-shaped or enterprise-shaped. Sealant should be applied at joints. The gaskets between flanges shall meet the planning requirements.

2、法蘭聯(lián)接時(shí)，按要求墊好墊料，然后把兩個(gè)法蘭先對正，穿上幾顆螺栓并戴上螺母，不要上緊。再用尖沖塞進(jìn)未上螺栓的螺孔中，把兩個(gè)螺孔撬正，直到一切螺栓都穿上后，擰緊螺栓。緊螺栓時(shí)應(yīng)按十字交叉逐步均勻的擰緊。風(fēng)管聯(lián)接好后，以兩頭法蘭為準(zhǔn)，拉線檢查風(fēng)管聯(lián)接是否平直。

2. When connecting flanges, pad the padding according to the requirements first, then put the two flanges in the right direction, put on several bolts and put on nuts, do not tighten. Then punch the bolts into the holes without bolts, pry the two holes straight, until all the bolts are put on, tighten the bolts. When tightening the bolt, it should be tightened evenly and gradually according to the cross. After the connection of the air duct is completed, the flange at both ends shall be taken as the standard, and the drawing line shall be checked to see whether the connection of the air duct is straight.

3、不銹鋼風(fēng)管法蘭聯(lián)接的螺栓，宜用同原料的不銹鋼制成，如用一般碳素鋼，應(yīng)按規(guī)劃要求噴涂涂料。

3. Bolts connected with flanges of stainless steel air ducts should be made of stainless steel with the same raw materials. If common carbon steel is used, coatings should be sprayed according to planning requirements

4、鋁板風(fēng)管法蘭聯(lián)接應(yīng)選用鍍鋅螺栓，并在法蘭兩頭墊鍍鋅墊圈。

4. Galvanized bolts should be selected for flange connection of aluminium sheet air duct, and galvanized gaskets should be cushioned at both ends of flange.

5、非金屬風(fēng)管聯(lián)接兩法蘭端面應(yīng)平行、緊密，法蘭螺栓兩頭應(yīng)加鍍鋅墊圈;復(fù)合材料風(fēng)管選用法蘭聯(lián)接時(shí)，應(yīng)有防冷橋辦法。

5. The ends of flanges of non-metallic air ducts should be parallel and close, and the ends of flange bolts should be galvanized gaskets; when flanges of composite air ducts are selected, the method of cold-proof bridge should be adopted.

6、聯(lián)接法蘭的螺栓應(yīng)均勻擰緊，其螺母宜在同一側(cè)。

6. The bolts of the connecting flange should be tightened evenly, and the nuts should be on the same side.

二、風(fēng)管無法蘭聯(lián)接

2. Air duct can not be connected in blue

1、承插式風(fēng)管聯(lián)接：適用于矩形或圓形風(fēng)管聯(lián)接。先制作聯(lián)接管，然后刺進(jìn)兩頭風(fēng)管，再用自攻螺栓或拉鉚釘將其緊密固定，風(fēng)管聯(lián)接處的四周應(yīng)一致，無明顯的彎曲或褶皺;內(nèi)涂的密封膠應(yīng)無缺，外粘的密封膠帶應(yīng)張貼結(jié)實(shí)、無缺無缺陷。

1. Socket-and-socket air duct connection: suitable for rectangular or circular air duct connection. Firstly, make connecting pipe, then pierce into two air ducts, then fix it tightly with self-tapping bolt or rivet. The air duct connection should be uniform around, without obvious bending or folding; the inner sealing glue should be intact, and the outer adhesive sealing tape should be sturdy and flawless.

2、薄鋼板法蘭方法風(fēng)管聯(lián)接：要求彈性插條、彈簧夾或緊固螺栓的間隔不應(yīng)大于150mm，且分布均勻，無松動(dòng)現(xiàn)象。

2. Air pipe connection by thin plate flange method: Elastic inserts, spring clamps or fastening bolts should not be more than 150 mm apart, and should be evenly distributed without loosening.

3、插條式風(fēng)管聯(lián)接：適用于矩形風(fēng)管，要求聯(lián)接后的板面應(yīng)平坦、無明顯彎曲。

3. Plug-type air duct connection: It is suitable for rectangular air duct, requiring that the plate surface after connection should be flat and without obvious bending.
