Problems solved by technology

However, many explosion-proof valves currently on the market have unsatisfactory pressure relief and flame extinguishing effects. When the pressure and flame generated when the crankcase explodes are large, it cannot completely extinguish the flame.

Abstract

The invention discloses a flame-retardant device assembly and a flameproof type anti-explosion valve using the flame-retardant device assembly. The flame-retardant device assembly is characterized in that the flame-retardant device assembly comprises an inner layer flame-retardant sheet group and an outer layer flame-retardant sheet group; the inner layer flame-retardant sheet group and the outer layer flame-retardant sheet group each consist of a plurality of annular flame-retardant sheets arranged axially; the axial sections of the flame-retardant sheets are wave-shaped; a wave-shaped extinguishing channel is formed between every two axial adjacent flame-retardant sheets; an annular inner layer filter screen is arranged on the inner side of the inner layer flame-retardant sheet group; and an annular outer layer filter screen is arranged between the inner layer flame-retardant sheet group and the outer layer flame-retardant sheet group. The flame-retardant device assembly has the advantages that when components like a crank case is exploded, generated flame and pressure are evenly dispersed through the inner layer filter screen, and then the evenly dispersed flame is completely extinguished through the extinguishing channels of the inner layer flame-retardant sheet group, the extinguishing channels of the outer layer flame-retardant sheet group and the outer layer filter screen, particularly large flame generated during the explosion can be completely extinguished by the flame-retardant device assembly, the extinguishing efficiency is high, and pressure relief and extinguishing effects are good.

Description

technical field [0001] The invention relates to an explosion-proof valve, in particular to a flame retardant assembly and a flame-resisting explosion-proof valve using the assembly. Background technique [0002] The internal combustion engine (including diesel engine, gasoline engine, and combustible gas engine) is a very complex moving machine. When it is running, internal moving parts such as crankshaft, cylinder liner, and piston will generate a lot of heat due to mutual friction. These frictions and The heat requires the oil in the crankcase to lubricate and cool, creating a large amount of oil vapor. In some extreme cases, the friction pairs between them will bite due to poor cooperation, which is commonly referred to as crankshaft lining, piston cylinder liner and cylinder, which will generate a lot of heat, which is enough to ignite the oil and gas. Thereby producing crankcase explosion accident. In order to prevent accidents from causing damage, a flame-resistant e...
