先导式溢流阀，DB10B

 

产品概述

DB10B型先导式溢流阀是一种高效、稳定的液压压力控制元件，广泛应用于各类工业液压系统中。该阀采用先导控制技术，通过主阀和先导阀的协同作用实现精准的压力调节，适用于中高压工况下的溢流、稳压及系统卸荷功能。其核心特点是结构紧凑、响应灵敏，能够在复杂工况下保持稳定的压力输出，同时具备低噪声和长寿命等优势。DB10B系列阀体采用高强度铸铁材料，内部流道经优化设计，确保大流量通过时压力损失最小化，满足不同液压设备的多样化需求。816

工作原理

DB10B先导式溢流阀由主阀芯和先导阀两部分组成。系统压力油通过主阀芯下端作用，同时经阻尼孔传递至先导阀锥阀。当系统压力超过先导阀弹簧设定值时，锥阀开启，主阀芯上腔压力油通过内部通道回流，使主阀芯抬升实现溢流。通过调节先导阀弹簧预紧力可灵活调整系统压力。该设计既保证了高压下的快速响应，又通过多级阻尼结构减少了压力波动，尤其适用于需要精密压力控制的场合，如工程机械、冶金设备等。512

技术特点

DB10B系列采用二节同心锥阀结构，主阀与先导阀均选用耐磨合金材料，确保长期使用中的密封性能。阀体集成铸造流道设计大幅提升了流通效率，最大工作压力可达31.5MPa，适配矿物基液压油介质。其模块化设计支持内供内排、外供外排等多种控制油组合方式，用户可根据系统需求选择不同配置。特殊的主阀芯面积比设计使得启闭特性更为平缓，有效降低液压冲击，显著延长泵阀使用寿命。1025

应用领域

本产品适用于机床、注塑机、船舶液压系统等场景，能实现多级压力控制和安全保护功能。在工程机械中可配合电磁换向阀组成卸荷回路，优化能源利用；在冶金设备中可精准控制轧机液压系统压力，确保设备稳定运行。其分体式结构设计便于安装维护，对空间要求较低，可灵活适配各类液压站布局。典型应用还包括造纸机械的压力保持、风电设备的制动系统等高压场合。719

产品优势

DB10B系列通过优化先导阀阻尼特性和主阀复位弹簧参数，在同等通径下具有更宽的调压范围和更小的压力振摆。与传统直动式溢流阀相比，其先导级控制显著降低了调节力矩，使得手动调压更为轻便精准。阀体表面经特殊防锈处理，适应高温高湿环境；所有密封件采用耐油橡胶材料，确保长期使用无泄漏。产品经过严格出厂测试，各项性能指标均达到行业领先水平。1722

Product Introduction

The DB10B pilot-operated relief valve is a high-performance hydraulic pressure control component designed for industrial hydraulic systems. Featuring a two-stage concentric poppet structure, it combines a main valve with a pilot valve to achieve precise pressure regulation up to 31.5MPa. Its compact design integrates optimized internal flow paths to minimize pressure drop during high-flow operations, making it suitable for diverse applications requiring stable pressure control under medium-high pressure conditions. The valve body is constructed from high-strength cast iron with enhanced corrosion resistance. 828

Operational Principle

In the DB10B design, system pressure acts on the main spool while simultaneously transmitting to the pilot cone valve through damping orifices. When system pressure exceeds the preset value of the pilot spring, the cone valve opens to release pressure from the upper chamber of the main spool, causing the main valve to lift and divert excess flow. This staged pressure relief mechanism ensures rapid response during pressure surges while maintaining smooth operation. The adjustable pilot spring allows flexible pressure setting within the specified range. 525

Key Features

  1. Dual-stage pressure control: The pilot valve provides sensitive pressure feedback while the main valve handles high flow rates.
  2. Versatile configurations: Supports internal/external drain options with X and Y ports for customized hydraulic circuit integration.
  3. Low-noise operation: Precision-machined damping components reduce fluid turbulence and vibration.
  4. Maintenance-friendly: Modular design enables easy disassembly for inspection without full system shutdown.
  5. Wide compatibility: Suitable for mineral-based hydraulic fluids within -20°C to 80°C operating range. 1626

Typical Applications

This product series is widely implemented in injection molding machines for cavity pressure control, construction machinery for overload protection, and steel rolling mills for hydraulic cylinder pressure stabilization. Additional use cases include:

  • Plastic extrusion equipment pressure regulation
  • Marine hydraulic steering systems
  • Wind turbine brake circuits
  • Industrial press safety relief circuits
    The valves compact footprint allows installation in space-constrained environments. 719

Performance Advantages

Compared to conventional relief valves, the DB10B demonstrates superior performance in:

  • Pressure stability: ≤±0.5% pressure fluctuation at rated flow
  • Response time: <50ms full-stroke actuation
  • Leakage control: Internal leakage <5mL/min at maximum pressure
  • Service life: Over 1 million cycles under standard testing conditions
    The product undergoes rigorous quality verification including flow characteristic tests and endurance trials to ensure reliable operation. 1722
