Product Overview

The small quick opening blind plate is a specialized pipeline fitting for small-bore pipeline plugging operations. It features a compact structure and quick-switch mechanism, enabling one operator to complete the blind plate insertion/removal within 3-5 minutes. With optional electric actuation, it offers enhanced safety and efficiency, making it ideal for frequent maintenance and isolation tasks in process pipelines.

Core Structure & Components

  • Handwheel / Chain Wheel Set: For manual operation to adjust and lock the blind plate position.
  • Screw Pair: Transmits torque to loosen the valve body and rotate the blind plate.
  • Left/Right Valve Body: Forms the main sealing structure with the blind plate.
  • Sliding Blind Plate: The core component for pipeline isolation and opening.
  • Bellows Compensator: Absorbs thermal expansion and ensures sealing reliability.

Key Advantages 

  • Quick Operation: Completes plugging in 3-5 minutes, significantly reducing downtime.
  • Labor Saving: Only one operator required, lowering labor costs.
  • Flexible Drive: Supports manual and electric actuation to meet different site requirements.
  • Wide Compatibility: Suitable for gas, liquid, and mixed media, with customizable materials.
  • Reliable Sealing: Adopts high-performance sealing materials, ensuring zero leakage under design conditions.

Application Industries

  • Refining Industry: Ethylene furnaces, coke removal lines, steam pipelines, separator isolation, flare gas lines, etc.
  • Chemical Industry: Reactor blowdown ports, chemical cleaning isolation devices, regenerated gas pipelines, transfer pipelines, mixed medium pipelines, etc.
  • Cement Industry: Finished product pipelines, oil depot tanks, petrochemical storage tanks, natural gas storage tanks, loading/unloading stations, etc.

Why Choose This Small Quick Opening Blind Plate?

  • Efficient Maintenance: Minimizes pipeline downtime and improves production efficiency.
  • Safe Operation: Optional electric actuation reduces manual operation risks in hazardous environments.
  • Customizable: Supports custom sizes, materials, and flange standards to meet project-specific needs.
