New Product Introduction: JLX Plug Valve Grinding Machine

The JLX plug valve grinding machine is a new generation of valve grinding equipment developed by Zhejiang Youji Machinery Technology Co., Ltd. The company owns independent intellectual property rights and an invention patent ZL202110071861.9. It is a specialized device for grinding the sealing surface of hard-seal plug valves, aiming to improve grinding accuracy and work efficiency, replacing the old-fashioned grinding machines and manual grinding.

JLX Plug Valve Grinding Machine Core Features and Functions

Grinding Principle: Based on grinding processing theory, this equipment uses gearbox technology to drive the spindle and a hydraulic motor to achieve stepless speed regulation and forward/reverse rotation (360 degrees forward, 360 degrees reverse). The unique “up and down jump” function (5 up and down movements per revolution) avoids damage to the valve body and valve core sealing surfaces, improving processing consistency.

Structural Design: The grinding head is connected to the telescopic rod via a universal joint, and its lifting and lowering are controlled by a hydraulic cylinder to achieve flexible adjustment of the sealing surface pressure; the clamping mechanism supports vertical adjustment of the valve body and valve core plug, reducing clamping errors. 1. Automation and Applicability: Integrating electromechanical, hydraulic, and lubrication circulation systems, it boasts a high degree of automation. It is suitable for plug valves with nominal diameters of DN50-200mm (JLX-200 type), DN200-400mm (JLX-400 type), and DN300-600mm (JLX-600 type). After grinding, the surface has a high degree of smoothness, and the sealing fit can reach approximately 90%. The equipment is available in single-station and two-station configurations, which users can select according to their needs. Grinding System Operation Procedure:
1. Start the hydraulic system. Manually fix the valve body on the T-shaped worktable and connect the grinding plug to the equipment.

2. Evenly apply grinding sand or grinding paste to the valve body or grinding plug.

3. Manually operate the lifting cylinder to lower the grinding plug, stopping it within 5-10mm of the sealing surface.

4. Manually operate the hydraulic motor and reciprocating cylinder to make the grinding plug reciprocate up and down and rotate.

5. Manually operate the lifting cylinder to lower the grinding plug until the reciprocating grinding plug contacts the valve body sealing surface at the lowest point of the reciprocating motion, and grinding begins.

6. The rotation speed is adjusted by the hydraulic flow rate. The user needs to select a suitable grinding compound (e.g., coarse or fine grinding) according to the valve diameter and material, and a floating grinding method can be used to optimize the fit.
