Abstract

The invention discloses a pipeline fire barrier. The pipeline fire barrier comprises a valve and a fire blockage device; the valve comprises a first valve body, a second valve body, large flange discs and small flange discs, the first valve body and the second valve body are conical, the large flange discs and the small flange discs are fixed to the two ends of the first valve body and the second valve body correspondingly, the large flange discs and the small flange discs are each evenly provided with four connecting holes, the small flange discs are fixedly connected with a pipeline through bolts, and the positions, between the large flange discs, on the first valve body and the second valve body are fixedly connected through bolts. The fire blockage device comprises a first fire blockage plate and a second fire blockage plate. The first fire blockage plate is fixedly connected with the inner wall of the first valve body, and the second fire blockage plate is fixed to the inner wall of the second valve body. According to the pipeline fire barrier, due to the fact that a corrugated steel strip and a flat steel strip are both in a V shape, the length of the pipeline can be increased, the contact area can be increased, and the better fire blockage aim is achieved.

Description

technical field [0001] The invention relates to the technical field of flame arresters, in particular to a pipeline flame arrester. Background technique [0002] The pipeline flame arrester is a safety device used to prevent the hydrogen flame from spreading outward. It consists of a solid material (firestop element) with many small channels or gaps through which gas can pass. It is required that the gap or channel of the fire arresting element be as small as possible, so when the flame enters the flame arrester, it is divided into many small flame flows by the fire arresting element, and the flame flow is quenched due to heat transfer (gas is cooled) and wall effect. [0003] The fire arresting pipes of the existing pipeline fire arresting pipes are all small internal pipes, which lead to low fire arresting efficiency and are not conducive to fire arresting; the existing pipe flame arresters are not tightly fixed. Contents of the invention [0004] The object of the pre...
