FMT-GX-350/650 Type Gate Valve Grinder

The FMT-GX-350/650 Gate Valve Grinder is designed based on advanced domestic and international models of valve grinders used in nuclear power systems. Leveraging years of accumulated expertise, it combines this knowledge with the current wear conditions and repair requirements of valves in China, making it a highly efficient, precise, versatile, and user-friendly piece of specialized equipment for on-site maintenance. Key features include: 1. Advanced, machine-specific settings that enable precise restoration of sealing surfaces on both valve bodies and valve discs. 2. The main assembly features a quick-release, short-pitch square-threaded design for convenient and rapid screwing, disassembly, and reassembly. 3. A compact clamping and pressurization mechanism allows the grinding head housing to be easily adjusted in three dimensions—up/down, left/right, and forward/backward.

Product Introduction

　　The FMT-GX-350/650 gate valve grinder is designed based on advanced models of valve grinders used in domestic and international nuclear power systems. Leveraging years of extensive professional expertise, it combines insights into the current wear patterns and repair needs of valves in China, making it a highly efficient, precise, versatile, and user-friendly piece of specialized equipment for on-site maintenance.

　　Key features:

　　1. Advanced dedicated machine settings capable of repairing the sealing surfaces of valve bodies and valve discs.

　　2. The main assembly features a quick-release short-pitch square-threaded structure for convenient and rapid screwing, disassembly, and reassembly.

　　3. The clamping and pressurizing mechanism allows the grinding head assembly to be easily adjusted in three dimensions—up/down, left/right, and forward/backward. Additionally, the output of the grinding head assembly features a ball-head floating design, ensuring optimal contact between the grinding disc and the workpiece’s sealing surface, thereby maintaining precise grinding accuracy.

　　4. Advanced eccentric oscillation and epicyclic motion generate a grinding path that closely mimics manual polishing, ensuring the ground surface achieves an exceptionally high level of flatness.

　　5. A high-strength mechanism and an ultra-thin, rigid grinding disc with high precision can maintain exceptional accuracy even under conditions of significant lateral pressure.

　　6. This model is equipped with a valve seat grinding bracket that allows for electrically adjustable tooling angles (0–15 degrees), as well as an integrated electric spring-pressurizing device. This device ensures precise, repeatable pressure application onto the sealing surface, enabling effortless, rapid, and high-quality valve seat lapping.

　　7. For rough grinding, high-quality resin-bonded diamond tools are used to eliminate defects on the grinding surface. After this step, precision finishing is carried out using shaped sandpaper—backing adhesive sandpaper is not employed. This method is easy to use, significantly boosting both efficiency and product quality. The resulting grinding accuracy achieves radial matching greater than 80%, with a surface roughness of just 0.2 μm, making it particularly well-suited for applications involving both air and water conditions.
