Product Overview

The three-point quick opening blind plate is a specialized pipeline fitting for large-bore low-pressure pipeline plugging operations. It features a three-point clamping structure and a quick-switch mechanism, enabling one operator to complete the blind plate insertion/removal within 3-5 minutes. With optional electric, pneumatic or hydraulic actuators, it offers enhanced safety and efficiency, making it ideal for frequent maintenance and isolation tasks in large-diameter process pipelines.

Core Structure & Components

Travel Plate Actuator: Drives the blind plate to slide in and out, realizing pipeline on-off.
Support Base: Provides stable support for the entire mechanism.
Clamp Release Actuator: Loosens the clamping force to allow blind plate rotation.
Movable/Fixed Blind Body: Forms the main sealing structure with the sliding blind plate.
Pulley & Linkage Mechanism: Guides the blind plate movement and transmits torque.
Screw Pair: Converts rotary motion to linear motion for precise position adjustment.

Key Advantages

Large Bore Adaptability: Covers DN150-DN1600, suitable for large-diameter low-pressure pipelines.
Quick Operation: Completes plugging in 3-5 minutes, significantly reducing downtime.
Multiple Drive Options: Supports manual, electric, pneumatic and hydraulic actuation to meet different site requirements.
Safe & Efficient: Replaces manual operation, reducing labor intensity and operational risks.
Reliable Sealing: Adopts high-performance sealing materials, ensuring zero leakage under design conditions.
Customizable: Supports custom sizes, materials and flange standards to meet project-specific needs.

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 Three-Point Quick Opening Blind Plate?

Efficient Maintenance: Minimizes large-diameter pipeline downtime and improves production efficiency.
Safe Operation: Multiple actuator options reduce manual operation risks in hazardous environments.
Large Bore Compatibility: Covers DN150-DN1600, meeting the needs of large-scale industrial pipelines.
Compliant: Meets national and international standards, ensuring compatibility and reliability.
Long Service Life: High-quality materials and robust three-point clamping design extend the product’s service life.
