Fig.3 Geometrical modeling of part “Body”
For the generation of three-dimensional geometric model of the designed assembled unit is used developed a database of component parts of the valve.
On Fig.4 is shown a 3D geometrical model of safety overflow valve and on Fig.5 - a cross section of assembly unit with graphical system SolidWorks. On Fig.6 is shown a exploded drawing of assembly unit of safety overflow valve, and on Fig.7- 2D assembly drawing of design valve on the base of 3D geometrical model made with graphical system SolidWorks.
