Abstract

The invention discloses a flame retardant piece for a modular internal concave type anti-explosion valve. The flame retardant piece is in a round ring shape, more than one flow turbulent columns are arranged on the flame retardant piece, and the flow turbulent columns comprise windward sides and lee sides; the windward sides of the flow turbulent columns are of an internal concave type structure,or the lee sides of the flow turbulent columns are of an internal concave type structure, or the windward sides and the lee sides of the flow turbulent columns are of an internal concave type structure; the flow turbulent columns at the front raw are located at front center of a gap of the two adjacent flow turbulent columns at the rear row, and the gap of the two adjacent flow turbulent columns at the rear row is smaller than the width of the flow turbulent columns at the front raw; and four installation holes are formed in the center of the flame retardant piece. The flame retardant piece for the modular internal concave type anti-explosion valve has the characteristics of compact structure, high heat transmission efficiency, high flame quenching speed, stable performance, modular designand convenient maintenance.

Description

technical field [0001] The invention relates to a modular concave flame retardant, in particular to a flame retardant sheet for deflagration flames of Class A combustible gases. Background technique [0002] Flame retardant is a kind of safety equipment widely used in industry. It is used in the pipeline system for conveying combustible gas, oil vapor recovery system and combustible gas discharge system to avoid explosion accidents. For example, in the shipbuilding industry, the long-term continuous operation of the ship will cause local overheating of the parts in the crankcase of the diesel engine, and the heat generated will cause the particles from the lubricating oil in the crankcase and the leakage of the piston ring to form a highly flammable oil mist mixture. When the oil mist mixture reaches a certain concentration and the temperature reaches the temperature to detonate the mixture, the crankcase explosion will be caused. A crankcase explosion can easily lead to a ...
