ANTI-EXPLOSION PANEL WITH SAFETY SLEEVE Russian patent published in 2017 - IPC E04B1/92 

FIELD: fire safety.

SUBSTANCE: anti-explosion panel with a safety sleeve containing metal armoured frame with metal armoured skin and lead-filler having four fixed support sleeves in the ends, and four support rods, telescopically inserted into the fixed support sleeves of the panel, embedded in the cover of the explosive object, the filler is made in the form of an air-lead disperse system, wherein the lead is made in the form of a crumb, and the support rods are made elastic, wherein the panel additionally comprises poroelastic destructible single-action elements, which are fixed on the support rods to the support sheets by a damping bed, connected with screws to coaxially located flange sleeve, upper flange of which is connected to the damping bed, and the lower flange - with a clamping element of sleeve type with grooves for fixing one of the ends of the elastic element made in the form of a conical spring, the other end of which rests against a glass with a central hole, wherein a rod is coaxially placed, and on the outer surface of the flange sleeve a safety sleeve is installed coaxially to the rod, the safety sleeve is made of a brittle destructible material, such as porcelain or glass of "triplex" type, and the glass is also made of a brittle destructible material, such as porcelain, and is fixed with its shell to the clamping element with screws, and the coaxially located flange sleeve, the upper flange of which is connected to the damping bed and the lower flange - to the clamping element of sleeve type, is made of vibration cushioning material, such as polyurethane. To prevent the cut of support sheets from support rods, an elastic element made in the form of a cylindrical spring, which rigidity is more than rigidity of conical spring, is additionally placed on the outside of the safety sleeve, coaxially and axisymmetrically.

EFFECT: increasing the explosion protective devices operation reliability in case of emergency explosion at the facility, and providing smooth damped return of these structures into the original position after the explosion without breakage.
