Four structural types: pressure-ring type, clamp-type, buckle-type, and fixed-pressure-ring type
Vertical Lock-Ring Type Quick-Open Blind Plate
The switch is lightweight and can be easily opened or closed by one person in under a minute, with straightforward operation. It also features a safety interlock device and complies with relevant provisions outlined in the national industry standards SY/T0556, "Technical Specifications for Quick-Acting Blind Flanges," as well as the "Safety Supervision and Inspection Regulations for Stationary Pressure Vessels."
Horizontal Lock-Ring Type Quick-Open Blind Plate
Before closing the blind plate, this device must be properly installed; otherwise, the equipment cannot be pressurized. Before opening the blind plate, this device must first be deactivated to safely release any residual pressure inside the equipment—otherwise, the blind plate will remain locked and unable to open.
Vertical Clamp-Type Quick-Open Blind Plate
Featuring excellent reliability, it is the ideal choice for high-pressure applications; moreover, it boasts a wide range of applicability—suitable for high, medium, and low pressures alike—and is particularly well-suited as a blind flange for large-diameter pipes with diameters of 1500 mm or greater.
Horizontal Clamp-Type Quick-Open Blind Plate
The blind plate represents a fully localized, domestically produced version of the quick-opening blind plate developed by Italy's FAI company—it features a three-lip clamp design, which is significantly superior to the earlier two-lip clamp models used domestically.
