通风管道与附件的制作及安装
Manufacture and installation of ventilation pipe and accessories
1、在第一道密闭阀门至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 pipes and fittings from the first closed valve to the mouth of the project shall be made of 2-3mm thick steel plate by welding. The weld should be full, uniform 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封槽的法兰连接,其接触应平整;法兰垫圈应采用整圈无接口橡胶密封圈。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。
2. The ventilation pipes in the contaminated area shall be welded. The ventilation pipe and airtight valve shall be connected by flange with sealing groove, and the contact shall be smooth; the flange gasket shall be a whole ring of rubber sealing ring without interface. 3. The steel plate thickness of ventilation pipe and accessories in the main project shall meet the design requirements. When the design has no specific requirements. The thickness of steel plate shall be greater than 0.75mm.
4、工程测压管在防护密闭门外的一端应设有向下的弯头;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,其接口应采橡胶托辊 槽型托辊 皮带托辊 平行托辊 保定搬家 保定搬家电话 保定搬家公司 保定搬家 铜鼎 铜狮子 用焊接。
4. One end of the engineering piezometer pipe outside the protective airtight door should be provided with a downward elbow; the other end should be set in the ventilation room or control room, and a ball valve should be installed. The connection of the pressure measuring tube passing through the anti-virus channel shall be welded.
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 decontamination sampling pipe of ventilation pipe shall be made at the same time as the pipe. The measuring hole and decontamination sampling pipe 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. The air flow direction, valve opening and closing direction and opening degree in the ventilation pipe shall be clearly and accurately marked.
