AI Technical Summary
Technical Problem
The existing powder metallurgy valve seats have a simple structure and poor combination connection effect, which affects the installation work.
Method used
The system employs a combination structure of two sets of locking components, bolt rods, positioning plates, and damping rods. The locking components are moved by the fastening groove of the bolt rods, which pushes the positioning buckle into the inner wall of the valve for fixation. Combined with the outer connecting ring and the valve core mounting sleeve, the system provides combined limiting to ensure stable positioning.
Benefits of technology
It improves installation efficiency and positional stability, adapts to different working environments, is easy to operate, and meets long-term working needs.

Abstract
This utility model discloses a combined assembly structure for a powder metallurgy valve seat, belonging to the technical field of powder metallurgy valve seats. The combined assembly structure includes a valve seat body and two locking components. The upper and lower ends of the assembly port are each provided with an integrally formed positioning port. Positioning plates are welded to the upper and lower ends of the locking components. This utility model solves the problem that existing powder metallurgy valve seats suffer from a simple structure, poor assembly connection, and hindered installation during actual use. The utility model uses a fixed outer connecting ring to maintain the front and rear positions of the valve seat body. The locking components are then inserted to fix both sides of the valve seat body. By rotating the fastening groove of the bolt rod, the locking components move, pushing them and the positioning buckles into the inner wall of the valve for fixation. This design is convenient to operate, adaptable to different working environments, and easy to use. The combined assembly structure improves installation efficiency.
