Proper maintenance and regular inspection of gate valve bodies are essential to ensure their longevity, reliability, and optimal performance. Here are some best practices for the maintenance and inspection of gate valve bodies: Remember, if you are uncertain or inexperienced in gate valve maintenance, consult with qualified professionals or...
After determining the optimal process parameter group, reset the process parameters according to the optimized process for numerical simulation. The optimized results of shrinkage porosity and porosity are compared with the results of traditional schemes, as shown in Figure 1. From the figure, it can be seen that the...
The design of the gating system directly affects the quality of investment castings. The gating system is generally composed of a gate cup, a sprue, a transverse sprue, and an inner sprue. Due to the unique structure of the ball valve, changing the structure and size of the pouring...
For the convenience of analysis, this article only conducts defect analysis on a single investment casting. The pouring system structure of 304 stainless steel ball valve under traditional technology is a stepped pouring system, and the distribution of shrinkage porosity and shrinkage defects is shown in Figure 1. Through...
Although the redesigned pouring system significantly reduced the shrinkage and porosity of the ball valve, it did not maximize the reduction of shrinkage and porosity defects. Therefore, it was adjusted and optimized from the perspective of process parameters. Based on the original traditional process parameters (pouring temperature 1550 ℃,...
Switch to the cast module, set simulation parameters, edit materials on the user defined page, edit the composition of 304 stainless steel in the table, and select zircon sand as the shell material. The traditional process parameters set the pouring temperature to 1550 ℃ and the preheating temperature of...
With the improvement of the world’s technological level, people’s demand for energy is increasing day by day, and material conservation has become the goal of various countries’ efforts. Traditional casting in the casting industry consumes both manpower and financial resources, while investment casting can better achieve minimal and no...
1.Modeling design According to the current casting process technology, it is decided to adopt the precision core assembly molding of cold box with high dimensional accuracy and good surface quality, and the core is made manually without the need for sand box fixation. According to the structure of the...
The casting process design of the flange ball valve was simulated by AnyCasting. The solidification sequence of the flange ball valve casting was obtained through simulation as shown in Figure 1. The solidification sequence of the flange ball valve casting was analyzed as follows: top, runner → middle of...
With the improvement of the transportation requirements for water, liquefied petroleum gas, natural gas and other media, the performance requirements for ball valves are becoming higher and higher. In order to improve the performance of ball valves, a set of casting process plan with higher performance must be designed....
