What should be paid attention to when designing the valve fittings for structural design

Jul 23, 2018

Under normal circumstances, when designing the valve fittings, the first consideration should be made to meet the requirements of easy to manufacture the model, the core box, and the convenient modeling. Therefore, the shape design of the valve fittings should be as simple as possible, so that it is easy to mold. As for the inner cavity, use the core as little as possible during casting, or not. If you want to use it, you must have enough process holes for exhausting.

 

At the same time, it should be noted that the direction of the mold should be maintained at an appropriate structural slope, which can enhance the structural strength of the valve fitting. Second, attention should be paid to reducing the tendency to create casting defects. It is therefore necessary to ensure that the wall thickness of the fitting is uniform and that good solidification conditions are maintained to prevent problems.

 

In addition, if a cast hole is provided in the planar wall of the valve fitting, it is recommended to use a flange for reinforcement, mainly to reduce the wall thickness. At the same time, a large horizontal plane should be avoided inside. In addition, the valve fittings should have good formability and the wall thickness must be at least below the specified range.
