Waterproofing system, useful in fluid distribution line of arc type plasma gun, comprises tubular element arranged in line on level of interface, and sealing components arranged between tubular element and conduit portions

摘要

The system comprises a tubular element (6) that is arranged in a line (3) on a level of an application interface (15) and comprises an axial passage provided with an input opening (8a) emerging upstream of the application interface and an output opening emerging downstream from the application interface, where the line includes a bypass fluid section of a first diameter, a first sealing component (10) arranged between the tubular element and a first conduit portion, and a second sealing component arranged between the tubular element and a second conduit portion. The system comprises a tubular element (6) that is arranged in a line (3) on a level of an application interface (15) and comprises an axial passage provided with an input opening (8a) emerging upstream of the application interface and an output opening emerging downstream from the application interface, where the line includes a bypass fluid section of a first diameter, a first sealing component (10) arranged between the tubular element and a first conduit portion, and a second sealing component arranged between the tubular element and a second conduit portion. The first and second sealing components are laid out on both sides of the application interface. The input opening has a second diameter higher or equal to a first diameter of a bypass fluid section of the line. The application interface is defined between the first and second conduit portions. The tubular element is present in cylindrical shape. The axial passage has a cylindrical internal profile of the second diameter. The internal profile includes a truncated upstream portion, where an opening angle of a cone is 60-90[deg] , and a cylindrical downstream portion of a third diameter lower than the first diameter of the bypass fluid section. A ratio of the third diameter and the first diameter is 0.6-0.8. The first and second sealing components are arranged in peripheral throats arranged in an offsite surface of a peripheral wall of the tubular element and formed of joints of an elastic material. The first and second conduit portions include a peripheral throat arranged in surfaces of portions located compared to the peripheral wall of the tubular element. The peripheral wall has a thickness of 0.1-0.3 mm, and is made of a stainless metallic material. An independent claim is included for a method for cutting a metal part.
