Abstract

Flame arrester block (230) for protection devices against flames propagation, comprising: at least one first plate (305) having an external perimeter and at least one aperture in a region inside the external perimeter; a second, closing plate (405) stacked on the at least one first plate (305) along a stacking direction (X), and, between the at least one first plate (305) and the second plate (405), at least one gap transversal to the packing direction (X). The at least one first plate (305) comprises a portion (325), located between the external perimeter and the at least one aperture, having reduced thermal conductivity, lower compared to the thermal conductivity of the material forming the remaining portion of the first plate (305).

IPC Classes  ?

• A62C 3/06 - Fire prevention, containment or extinguishing specially adapted for particular objects or places of highly inflammable material, e.g. light metals, petroleum products

Abstract

A valve body (100, 100', 100") for safety valves adapted to adjust a pressure in a tank of fluid, the valve body defining a cavity (105) inside the valve body is proposed. The valve body comprises: a plurality of openings (110a, 110b, 110c, 110d) provided in the valve body (100) to allow accessing the internal cavity of the valve body, at least two openings (110a, 110b, 110c, 110d) of said plurality of openings being provided on the valve body in such a way to lie on substantially parallel planes one with respect to the other, and a plurality of mechanical coupling portions (120a, 120b, 120c, 120d). Each mechanical coupling portion is provided in correspondence of a respective one of said at least two openings of the valve body, and each mechanical coupling portion is adapted to couple with a corresponding coupling portion of a further valve body.

Abstract

Flame arrester block (230; 230-1,230-2, 230-3, 230-4, 230-5, 2306) for protection devices against flames and/or explosions, comprising: at least one first plate (305) having an external perimeter and at least one aperture in a region inside said external perimeter, and a second, closing plate (310) stacked on said at least one first plate (305) along a stacking direction (X) and spaced apart (315) from the at least one first plate (305) so as to define, between said at least one first plate (305) and said second plate (310) a gap transversal to said packing direction (X).
