1. 通風(fēng)管內(nèi)氣流方向.閥門啟閉方向及開啟度，應(yīng)標(biāo)示清晰、準(zhǔn)確。

　　1. the direction of air flow in the ventilation pipe. The valve opening and closing direction and opening degree shall be marked clearly and accurately.

　　2. 濟(jì)南通風(fēng)管道工程在道密閉閥門工程口部的管道與配件，應(yīng)采用厚2-3mm的鋼板焊接制作，其焊縫應(yīng)飽滿.均勻.嚴(yán)密。

　　2. Ji'nan ventilation pipe project in the first closed valve to the mouth of the pipe and fittings should be welded by thick 2-3mm steel plate, the weld should be full, uniform, tight.

　　3.工程測壓管在防護(hù)密閉門外的一端應(yīng)設(shè)有往下的彎頭，另一端宜設(shè)在通風(fēng)機(jī)房或控制室，并應(yīng)安裝球閥。通過防毒通道的測壓管，其接口應(yīng)采用焊接。

　　3. the pressure measuring pipe of the project shall be provided with a downward elbow at one end of the protective airtight door, and the other end shall be arranged in the ventilation room or the control room, and the ball valve shall be installed. Through the measuring tube of the gas passage, the interface shall be welded.

　　4.染毒區(qū)的通風(fēng)管道應(yīng)采用焊接連接。通風(fēng)管道與密閉閥門應(yīng)采用帶密閉槽的法蘭連接，其接觸應(yīng)平整;法蘭墊圈應(yīng)采用整圈無接口橡膠密封圈。

　　4. the ventilation duct in the contaminated area shall be welded. The ventilation pipe and the airtight valve should be connected with flange with airtight groove, and the contact should be smooth. The flange washer should adopt the whole circle without interface rubber sealing ring.

　　5.通風(fēng)管的測定孔.洗消取樣管應(yīng)與管同時(shí)制作。測定孔和洗消取樣管應(yīng)封堵。

　　5. determination holes for ventilation pipes. Wash out sampling tubes shall be made simultaneously with tubes. The measuring hole and the decontamination sampling tube shall be sealed.

　　6. 主體工程內(nèi)通風(fēng)管與配件的鋼板厚度應(yīng)符合設(shè)計(jì)要求。當(dāng)設(shè)計(jì)無具體要求時(shí)，鋼板厚度應(yīng)大于0.75mm。

　　6. the thickness of the steel plate of the ventilation pipe and fittings shall comply with the design requirements. When the design has no specific requirements, the steel plate thickness should be greater than 0.75mm.

　　法蘭用料應(yīng)分類碼法放，露天防止應(yīng)采取防雨、雪措施.減少生銹現(xiàn)象。通風(fēng)管道應(yīng)碼放在平整無積水，寬敞的場地，碼放時(shí)應(yīng)按系統(tǒng)編號，整齊、合理、便于裝運(yùn)。

　　Flange material should be classified code method, open to prevent rain and snow measures should be taken to reduce the phenomenon of rust. The ventilation pipe should be stacked without water in the flat, spacious venues should be stacked according to system number, orderly, reasonable and convenient for shipment.

　　還需要注意在涂漆時(shí)應(yīng)使漆膜均勻，不得有堆積、漏涂、皺紋、氣泡及混色等缺陷。普通鋼板在壓口時(shí)必須先噴一道防銹漆，保證咬縫內(nèi)不易生銹。

　　It should also be noted that the paint film should be made even, without any defects such as accumulation, leakage, wrinkles, bubbles and mixed colors. Ordinary steel plate must be sprayed at the mouth of a rust proof paint, to ensure that the joints are not easy to rust.

　　要保持鍍鋅鋼板表面光滑潔凈，放在寬敞干燥的隔潮木頭 墊架上，疊放整齊。不銹鋼板、鋁板要里靠在木架上，不要平迭，以免拖動(dòng)時(shí)刮傷表面，下料時(shí)應(yīng)使用不產(chǎn)生劃痕的劃線工具。操作時(shí)應(yīng)使用木錘或有橡膠皮套的錘子，不得使用鐵錘，以免落錘點(diǎn)產(chǎn)生銹斑。

　　To keep the galvanized steel surface smooth and clean, put on the spacious dry wooden shelf, stacked neatly. Stainless steel plate, aluminum plate to depending on the gallows, not flat, so as not to drive when scratching the surface, should use the scribing tool does not produce scratches when feeding. The operation should use wooden hammer or rubber leather hammer, hammer shall be used, so as not to drop point rust.
