法兰机械柔性接头排水铸铁管与K型接头排水球墨铸铁管的连接

法兰机械柔性接头排水铸铁管与K型接头排水球墨铸铁管的连接应符合下列要求：

1安装前应清除直管、管件内外表面的污垢、杂物及承插、承插、法兰压盖结合面上的沉淀物；

2根据承口深度，在承口上划出安装线，使承口插入深度与实际深度之间有5mm的安装间隙，以保证管道的柔性抗震性能；

三。先在承口端插入法兰压盖，然后依次插入橡胶密封圈，使橡胶密封圈的小端朝向承口，大端对准安装线；

4将直管或管件的插口端插入承口，插入管与承口管的轴线应在同一直线上，橡胶密封圈应均匀靠近承口的倒角；

5将法兰上的密封圈与法兰上的密封圈对齐，使密封圈与法兰上的密封圈对齐。三孔压盖应交替拧紧，四孔或多孔压盖应按对角线方向逐步拧紧；

6调整并拧紧支撑（吊架）螺栓，以固定管道。

5.2.4建筑排水柔性接头铸铁管与塑料管或钢管连接时，当其外径相同时，可采用本规范5.2.3规定的方法；当外径不同时，可按相应的直径采用插入式或套筒式连接，或可以使用制造商的配套产品。接缝处使用的密封填料应符合密封要求。卫生洁具排水管与铸铁管柔性接头连接方法同上。

5.2.5建筑排水钢管的沟槽连接及安装应按下列步骤进行：

1检查坡口，坡口加工深度和宽度应符合相关要求；

2装配卡套，在橡胶密封套上涂润滑剂，放入卡套内；

三。适当松开卡套螺栓，将管子插入卡套内，并保持插入管子两端轴线一致；

4拧紧卡套上的螺栓，卡套内边缘应卡入槽中。

Connection between flange mechanical flexible joint drainage cast iron pipe and K-joint drainage ductile iron pipe

The connection between flange mechanical flexible joint drainage cast iron pipe and K-joint drainage ductile iron pipe shall meet the following requirements:

1. Before installation, the dirt and sundries on the inner and outer surfaces of straight pipes and pipe fittings and the sediment on the joint surface of socket, socket and flange gland shall be removed;

2. According to the depth of the socket, draw the installation line on the socket, so that there is a 5mm installation gap between the insertion depth and the actual depth of the socket, so as to ensure the flexible seismic performance of the pipeline;

3. Insert the flange gland at the socket end first, and then insert the rubber sealing ring one after another, so that the small end of the rubber ring is toward the socket, and the big end is aligned with the installation line;

4. Insert the spigot end of the straight pipe or fitting into the socket, the axis of the inserted pipe and the socket pipe should be in the same line, and the rubber sealing ring should be evenly close to the chamfer of the socket;

5. Align the flange gland with the screw holes on the flange plate at the socket, and tighten the connecting bolts to make the rubber sealing ring bear uniform force. The three hole gland should be tightened alternately, and the four hole or multi hole gland should be tightened step by step in the diagonal direction;

6 adjust and tighten the support (hanger) bolts to fix the pipe.

5.2.4 when building drainage flexible joint cast iron pipe is connected with plastic pipe or steel pipe, when their outer diameters are the same, the method specified in 5.2.3 of this specification can be used; when the outer diameters are different, the plug-in or sleeve type connection can be used according to the corresponding diameter, or the manufacturer's supporting products can be used. The sealing packing used at the joint shall meet the sealing requirements. The connection between the discharge pipe of sanitary ware and the cast iron pipe with flexible joint is the same as the above method.

5.2.5 the trench connection and installation of steel pipes for building drainage shall be carried out according to the following steps:

1. Check the groove, and the groove processing depth and width should meet the relevant requirements;

2. Assemble the ferrule, apply lubricant to the rubber sealing sleeve and put it into the ferrule;

3. Loosen the ferrule bolt appropriately, insert the tube into the ferrule, and keep the axes of both ends of the inserted tube in the same line;

4 tighten the bolts on the ferrule, and the inner edge of the ferrule should be stuck into the groove.

法兰机械式柔性接口排水铸铁管和K型接口排水球墨铸铁的连接

法兰机械式柔性接口排水铸铁管和K型接口排水球墨铸铁的连接应符合下列规定：

1 安装前，应将直管及管件内外表面粘结的污垢、杂物和承口、插口、法兰压盖结合面上的泥沙等附着物清除干净；

2 按承口的深度，在插口上画出安装线，使插入的深度与承口的实际深度间留有5mm安装空隙，以保证管道的柔性抗震性能；

3 在插口端先套入法兰压盖，相继再套入橡胶密封圈，使胶圈小头朝承口方向，大头与安装线对齐；

4 将直管或管件的插口端插入承口，插入管与承口管的轴线应在同一直线上，橡胶密封圈应均匀紧贴在承口的倒角上；

5 将法兰压盖与承口处法兰盘上的螺孔对正，紧固连接螺栓，使橡胶密封圈均匀受力，三孔压盖应交替拧紧，四孔或多孔压盖应按对角线方向依次逐步拧紧；
