1、 在一道密闭阀门工程口部的管道与配件，应采用厚2-3mm的钢板焊接制作,其焊缝应饱满、均匀、严密。

1. The piping and fittings of the first closed valve to the engineering port should be welded by thick 2-3mm steel plate. The welds should be full, even and tight.

2、染毒区的通风管道应采用焊接连接。通风管道与密闭阀门应采用带密闭槽的法兰连接，其接触应平整;法兰垫圈应采用整圈无接口橡胶密封圈。

2, the ventilation pipeline in the contaminated area should be welded. Ventilation pipes and closed valves shall be connected with flanges with closed grooves, and the contact shall be smooth; the flange gaskets shall be provided with a whole ring without interface rubber seals.

3、 主体工程内通风管与配件的钢板厚度应符合设计要求。当设计无具体要求时，钢板厚度应大于0.75mm。

3. The thickness of the steel plate of the ventilation pipe and fittings in the main project should meet the design requirements. When there is no specific requirement for design, the thickness of the steel plate should be greater than 0.75mm.

4、工程测压管在防护密闭门外的一端应设有往下的弯头，另一端宜设在通风机房或控制室，并应安装球阀。通过防毒通道的测压管，其接口应采用焊接。

4. One end of the engineering piezometric tube should be provided with a downward elbow at the end of the closed door, and the other end should be installed in the ventilator room or control room, and the ball valve should be installed. The interface should be welded through the pressure measuring pipe of the anti-virus passageway.

5、通风管的测定孔、洗消取样管应与管同时制作。测定孔和洗消取样管应封堵。

5. The measuring hole and cleaning sampling tube of the ventilating pipe should be made at the same time with the tube. The test hole and the washing tube should be blocked.

6、 通风管内气流方向、阀门启闭方向及开启度，应标示清晰、准确。

6. Airflow direction, opening and closing direction and opening degree of the ventilation pipe should be clearly marked and accurate.

7.材料表面油污应全部干净，以免铁锈或氧化物落于材料表面产生局部腐蚀。

7. the oil on the surface of the material should be cleaned up so as to avoid rust or oxide falling on the surface of the material to cause localized corrosion.

8.必须有一个单独的加工场地，为了不破坏镀锌钢板外的保护膜，工作场地较好铺设木板或者橡胶板，保持场地清洁。

8. it is necessary to have a separate processing site. In order not to destroy the protective film outside the galvanized steel sheet, the best work site is to lay a wood board or rubber plate to keep the site clean.
