VALVE DESIGN
Mold filling simulation
Solidification simulation temperatures and more . Therefore , valves must be designed and manufactured considering these conditions . Due to the challenging operating conditions and complex geometries , some valves are produced using casting methods . The difficulties and limitations inherent to the casting process , as well as international standards , customer requirements and operating conditions , must be taken into account during the design phase . The ball valves developed in this study have been designed to meet the requirements of the API6D design standard and other referenced standards such as ASME B16.10 , ASME B16.5 and ASME B16.34 . During the design process , the mechanical properties of ASTM A216 Gr . WCB quality cast carbon steel , which was chosen as the body material , were tested through tensile and hardness tests . Design calculations and analysis work were carried out based on these data . Static analyses were performed on components exposed to pressure , such as the body , sphere and bonnet part , to examine the loads and deformations experienced by these parts . Based on the results obtained , it was determined that the loads applied to the components are below the material ’ s yield strength , indicating that the design is highly suitable in terms of pressure . Static analysis simulations were set to 1.5 times the valve ’ s working pressure ( 19.6 Bar ), which corresponds to 29.4 ~ 30 Bar , as specified in the standards . Design calculations have been performed in accordance with the requirements specified in API6D and ASME B16.34 standards . The data obtained from these calculations align with the results of static analysis simulations conducted on the computer . As a result of these efforts , the design has been theoretically validated and a valve design has been developed that ensures maximum efficiency under operational conditions . All work performed at this stage was documented , resulting in the creation of a design package . After completing the final design work , the model production process for the body and bonnet parts to be manufactured using the casting method was initiated . In this process , model data was created with machining and shrinkage allowances provided according to the EN 8062- 3 standard requirements . To maintain maximum production efficiency during the design phase , the amount of machined surfaces was kept to a minimum . However , this process was carried out in a manner
