The body of faucets is moulded of pure copper H59-1 according to international standard. Thickness is symmetrical, generally during 2.5---3.0 mm. Hardware machining is made by super accurate machine. Using the international advanced method to check screw thread inside, screw thread outside, aperture, plug guage, etc. All the standard get to national standard. The flux of the products is 16 kg per minute. The airproof get to 3.2. Polishing parts is polished by advanced machine for eight times. The plane and straight line is handled by flat machine for nine times, and then handled by the wool wheel machine.
龙头主体原料采用同际标准的H59-1纯铜精制加工而成，铸造采用铁模进地浇铸，其壁厚均匀，一般在2.5－3.0毫米；金加工采用高精度双轴复合机进行加工，通过同际检测手段进行检测，内螺纹，通、止规，外螺纹，环规，孔径、塞规等工具检测都达到国家标准，产品的流量1分钟出水16kg，其密封光洁度达3.2；抛光全部采用先进的砂带机进行8道磨抛处理，平面和直型线条，采用平板机经过9道磨光工艺加工，最后再用羊毛轮进行清光处理。
For hydraulic test, each nozzle reinforcement will allow a screwed aperture 1/4 BSP with plug.
为便于水压试验，每个管口补强处应有一个1/4 BSP的内螺纹孔并配丝堵
To obtain rapidness in batch measuring of aperture, a system of electronic plug gauge, based on RIM-FODS, was put forward.
针对内孔零件批量快捷测量的问题，提出了基于反射式光强调制型光纤位移传感器的电子塞规测试系统。
According to the geometry of disk aperture and the direction of a fatigue crack around a disk aperture, the plug-in detection mode is chosen. Moreover, two eddy current probes with different configuration are proposed and compared with another probe.
根据盘孔几何结构和裂纹走向，选择探头插入式的检测方式，提出了两种不同结构形式的探头，并与另一种探头对比分析。
