管堵也叫闷头、堵头，是在水管安装好以后，用来暂时封闭出水口使用的，在安装龙头时会取下，在使用堵头时应注意尺寸大小必须与对应的管件相匹配。
Pipe plug, also known as stuffy head and plug, is used to temporarily close the outlet after the pipe is installed. When installing the tap, it will be removed. When using the plug, attention should be paid to the size matching with the corresponding pipe fittings.
管卡Pipe clamp
管卡是水暖安装中比较常用的一种管件，主要用于地面找平之前管道固定。在安装工程中为了更好的确定方向，建议先在固定处做好标记，后焊上焊接，嵌上管夹的下半部分，放上需固定管子。然后放上另一半管夹身和盖板，用螺钉拧紧。
Pipe clamp is a kind of pipe fittings commonly used in plumbing installation. It is mainly used for fixing pipes before leveling the ground. In order to determine the direction better in the installation project, it is suggested to mark the fixed part first, then weld it, insert the lower part of the pipe clamp, and put the fixed pipe on it. Then place the other half of the pipe clamp and cover plate, and tighten with screw.
绕曲弯管Winding elbow
也叫过桥，当两根水管在同一平面相交而不对接时，为了保证水管的正常使用，我们用绕曲弯过渡，就像拱桥一样，通过平面的避让来避过水管的直接相交。
Also known as bridge, when two water pipes intersect on the same plane and do not dock, in order to ensure the normal use of water pipes, we use curved transition, just like an arch bridge, through plane avoidance to avoid the direct intersection of water pipes.
生料带Raw meal belt
生料带是一种新颖的理想密封材料，用于管件连接处，在很大程度上增强管道连接处密闭性。生料带也被称为聚四氟乙烯，暖通和给排水管子中使用普通白色聚四氟乙烯带，天然气管道有其专门的聚四氟乙烯带。
Raw meal tape is a novel ideal sealing material, which is used in the joint of pipe fittings and greatly enhances the sealing of the joint of pipe. Raw material belt is also known as PTFE. The common white PTFE belt is used in HVAC and water supply and drainage pipes. The natural gas pipeline has its special PTFE belt.
