Product Description

 

Hydraulic Support Auxiliary Valves: Leveraging Cutting-Edge Technical Expertise

Category Working Principle Model Types Material & Characteristics
Function - Pressure Regulation: Uses relief valves to maintain system pressure (16-50 MPa). - Standard Model: Basic pressure/flow control for general support actions. - Valve Body: Stainless steel or cast iron (corrosion resistance, high strength).
  - Flow Control: Adjusts flow via throttle valves for actuator speed modulation. - High-Pressure Model: Optimized for 40-50 MPa systems in heavy-duty tasks. - Valve Spool: Hardened alloy steel (wear resistance, durability under abrasive conditions).
  - Directional Control: Electromagnetic/manual valves switch fluid paths. - Intelligent Model: Integrated with sensors for automated electrohydraulic systems. - Seals: Nitrile rubber or polyurethane (high-temperature and chemical resistance).
  - Safety Protection: Check valves prevent reverse flow; relief valves limit overpressure. - Compact Model: Lightweight design for narrow or inclined mining spaces. - Springs: Chrome silicon steel (fatigue resistance, stable elasticity).
Key Features - Modular design for quick maintenance. - Application-Specific Models: Customized for roof adjustment, conveyor shifting, etc. - Filter Elements: Stainless steel mesh (blocks particulates ≥25 μm).
  - Compatible with fire-resistant hydraulic fluids (e.g., water-glycol emulsions).   - Coating: Anti-corrosion coatings (zinc-nickel plating) for humid/acidic environments.
Performance - Rapid response (≤0.1s actuation time). - Pressure Range: 16-50 MPa. - Compliance: Meets mining safety standards (e.g., ATEX/Ex d I Mb explosion-proofing).
  - Leakage rate ≤0.1% under rated pressure. - Flow Capacity: 20-200 L/min (varies by model).
