Automatic retrieval of standard parts with matching assembly dimensions

The more standard components involved in the design reuse process, the more complex the assembly relationships become, and the more challenging the overall product design becomes. This complexity demands that designers possess strong experience and expertise. Typically, the design process follows certain established rules—both general design procedures and industry-specific knowledge. When this knowledge is integrated into a standardized parts library management system, it significantly enhances design efficiency and reduces the likelihood of errors. One key aspect of design process reuse is rapid assembly. This feature enables the system to automatically identify hole faces on the base component, calculate their dimensions, and then select and assemble standard parts that match those dimensions. Users can also choose pre-defined subassemblies, such as a bolt, washer, and nut combination, to streamline the assembly process. Based on the principles of knowledge reuse, the system was developed using UG as the core platform, with C and C++ programming languages employed to implement the standard parts library management system. This solution automates the design of standard components and greatly improves overall productivity. For example, during the quick assembly process, the user simply drags a bolt from the navigation bar to one side of the base part. The system then performs the following tasks: First, size matching—when the bolt is placed on a flat surface, the system calculates the thickness of the base part; if placed on a cylindrical surface, it calculates the diameter and height, then selects an appropriate bolt size for assembly. Second, assembly constraints—when placed on a plane, the system automatically applies a fitting constraint between the bolt and the base; when placed on a cylindrical surface, it generates a coaxial constraint between them. This approach not only simplifies the design workflow but also ensures consistency and accuracy, making it easier for engineers to focus on more complex aspects of the design. By leveraging automation and intelligent part selection, the system supports efficient and error-free design processes, ultimately reducing time-to-market and improving product quality.

Butterfly Valve

Butterfly valves are commonly used in piping systems to control and regulate flow and speed.

The use of butterfly valve is also relatively simple, easy to operate. And butterfly valve is widely used in all walks of life, is an important control fluid system equipment.

, for air conditioning system: A butterfly valve can control the flow of air conditioning pump and piping system to adjust the temperature of the air conditioning system, so that the air conditioning system can work more efficiently.

2, for water treatment: butterfly valve can be used for water treatment process, can effectively control and adjust the flow of water pipe, carefully adjust the appropriate quality of water.

3, used for power system: butterfly valve can also be used for power system, can effectively control and adjust the flow of water and pressure in the power system, to ensure the normal operation of the power system.

4, used for heating system: butterfly valve can also be used for heating system, can control the flow of hot water piping system and adjust the temperature of the heating system, in order to meet the temperature requirements of the house.

In general, the use of butterfly valves is very wide, from air conditioning systems to water treatment, from power systems to heating systems, a variety of industries can benefit from the use of butterfly valves. Moreover, butterfly valve structure is simple, easy to maintain, for enterprises is also an affordable choice.
