Pipe end type burning-resistant flame arrester

Abstract

The invention discloses a pipe end type burning-resistant flame arrester which comprises a shell assembly. A flame arresting grid is fixedly connected to the upper portion in the shell assembly through a bracket, a rainproof cap is connected to the top of the shell assembly through a springback assembly, a guide plate is fixedly connected to the inner wall of the shell assembly, a flame arresting net is fixedly connected between the two sides of the inner wall of the shell assembly and located below the flame arresting grid, and a connecting assembly is arranged between the rainproof cap and the bracket. The invention relates to the technical field of flame arresters. According to the pipe end type burning-resistant flame arrester, a guide plate can play a role in guiding flames, so that the flames can quickly reach the positions of the flame arresting net and the flame arresting grid, the flames are quickly extinguished, the tempering phenomenon is reduced, the flame arrester combination effect is better, the practicability is better, and under the fire working condition, the area temperature of the rainproof cap rises, a fusible column is fused, at the moment, the rainproof cap is bounced off under the action of double torsional springs, so that temperature is prevented from continuously accumulating, and burning resistance is achieved.

Description

technical field [0001] The invention relates to the technical field of flame arresters, in particular to a pipe-end type fire-resistant flame arrester. Background technique [0002] The flame arrester is a safety device used to prevent the spread of flames of flammable gases and flammable liquid vapors. It is generally installed in pipelines conveying flammable gases, or on ventilated tanks to prevent the passage of flames (deflagration or detonation) , consisting of a flame arrester core, a flame arrester shell and accessories. Flame arresters are also commonly used on pipelines transporting flammable gases. If the flammable gas is ignited, the gas flame will spread to the entire pipe network. In order to prevent this dangerous In case of accident, a flame arrester should also be used. The flame arrester can also be used on the pipeline with open flame equipment to prevent backfire accidents, but it cannot prevent the open flame combustion of flammable gases and liquids tha...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a pipe-end type burn-resistant flame arrester, which solves the problem that when the internal temperature of the rainproof cap is too high, tempering phenomenon is easy to occur, which has a certain degree of danger, and when the flame enters When the flame arrester is inside, it takes a long time to reach the flame arresting grid, the fire arresting effect is poor, and the practicability is low
