Flame arrester with alarm function

Abstract

The invention discloses a flame arrester with an alarm function, and belongs to the field of flame arresters, according to the scheme, when a flame arrester body leaks, leaked combustible gas is dispersed into a plurality of small gases by a dispersion and heat reduction mechanism, ammonium chloride powder is used for absorbing heat and reducing temperature, so that the small gases are in full contact with cold air, the heat transfer effect is enhanced, and the flame arrester is prevented from leaking. The pulling alarm mechanism drives a memory fin to deform and gather by means of heat of leaked gas, a pulling type control switch is pulled, an alarm lamp is driven to give an alarm, a worker is notified to conduct maintenance in time, the extrusion gas injection mechanism extrudes gas into a magnetic insulation bag body by means of movement of a pull rod, and the spraying heat absorption mechanism sprays the gas into the magnetic insulation bag body by means of expansion of the magnetic insulation bag body. The water solution is extruded by the magnet block under the repulsive action of the magnetic ball to be sprayed out and fall on the outer end of the leakage response ring, heat of small gas is absorbed through gasification, the ignition point is reduced, the safety is improved, maintenance by workers is facilitated, and the using effect of the flame arrester body is enhanced.

Description

technical field [0001] The invention relates to the field of flame arresters, more specifically, to a flame arrester with an alarm function. 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 fire arrester core, a flame arrester shell and accessories. [0003] During long-term use, the flame arrester is prone to wear and tear, resulting in the leakage of combustible gas, and the staff does not know the leakage of combustible gas in time, which will affect it. Therefore, it is necessary to add an alarm function to the flame arrester. Contents of the invention [0004] 1. technical problem to be solved [0005] In view of the problems existing in the prior art, the object of the present invention is to pro...
