Standard part templates in the library typically come in two forms: one is a standard part family template that includes various specifications, and the other is a standalone standard part template stored directly in the library. In CAD software, the way these templates are instantiated can differ significantly. In UG, for instance, the modeling process varies depending on which form of template is used. For parts belonging to a standard part family, the part family method is employed, where different-sized components within the family are created as instances. When calling these parts, they are treated as specific instances of the family members. On the other hand, for the second type of template, a more general modeling approach is used. During the calling process, the template file is adjusted to the required size and then cloned into the current assembly directory, ensuring that the original template in the standard part library remains unaffected. Reusable assembly design plays a crucial role in defining assembly relationships, but it is often time-consuming and error-prone throughout the design process. If all assembly relationships and parameters are manually defined by the user, especially in complex assemblies with many components, there is a high risk of mistakes or omissions. To address this challenge, numerous studies have been conducted in recent years both domestically and internationally. Approaches such as parameterized component-based automatic assembly and feature-based assembly have been proposed. This paper adopts a method that involves encapsulating assembly knowledge during the design process, including assembly relationships and features, while utilizing parametric standard parts to complete the assembly automatically. This approach is known as automatic assembly based on the reuse of assembly relationships. An assembly feature refers to a collection of geometric information and associated properties related to assembly within a standard part. By integrating these concepts, the design process becomes more efficient and less prone to errors. The use of standardized templates and reusable assembly features not only improves consistency across designs but also reduces the need for repetitive work. Furthermore, this methodology supports scalability, making it easier to adapt to different project requirements without starting from scratch. Overall, the combination of parametric modeling, assembly features, and knowledge encapsulation offers a powerful solution for modern assembly design workflows. Gate valve is a relatively common general-purpose valve, the use of a wide range of applications, mainly in water conservancy, metallurgy and other industries, its extensive use of performance has been recognized by the market.

Gate valve structure: gate valve is the use of the gate and seat to control the opening and closing of the valve. Gate valve mainly has a valve body, valve seat, gate, valve stem, valve cover, stuffing box, packing gland, stem nut, hand wheel and other components. Depending on the change of the relative position between the gate and the valve seat, the channel size can be changed and the channel can be cut off. In order to make the gate valve close tightly, the mating surface of the gate plate and the valve seat are ground.
