Abstract
The utility model discloses an explosion-proof fire barrier. A fire blocking net is arranged in upper and lower shells of the fire barrier and connected with the upper and lower shells through supports, so that the explosion-proof function of the fire barrier is effectively realized; the cross supporting plate type supports support and limit the fire blocking net, and the fire blocking net plays a role in blocking fire and cooling, so that possible explosive gases are cooled and extinguished in a flame passage of the fire blocking net, and a backfire phenomenon is effectively prevented. The explosion-proof fire barrier is reasonable in structure, easy to install, convenient to maintain and worthy of popularization and application.
Description
Technical field
The utility model belongs to explosion-proof auto parts machinery technical field, particularly a kind of Antiexplosion and fire-stopping unit.
Background technology
Spark arrester is to stop the propagation of flame of inflammable gas, liquid and high-temperature gas and prevent tempering and the safety device that sets off an explosion.At present, on the storage tank of inflammable gas or liquid and feed-line and in the exhaust emission pipeline of internal combustion engine, all needing to use spark arrester is stop propagation of flame and prevent tempering and set off an explosion, in case catch fire, propagation of flame and tempering are as easy as rolling off a log to set off an explosion, and its consequence that causes is with hardly imaginable.Traditional spark arrester all can only carry out the fire insulation cooling by the back-fire relief net.
The utility model content
The purpose of this utility model is to overcome the prior art deficiency, provides a kind of rational in infrastructure, and back-fire relief is effective, repair and maintenance Antiexplosion and fire-stopping unit easily.
For achieving the above object, the technical solution of the utility model is: a kind of Antiexplosion and fire-stopping unit, comprise the upper shell and the lower house that are fastened and connected, the connecting portion of upper shell and lower house arranges the back-fire relief net, described back-fire relief net both sides are the support that is connected with lower house of setting and upper shell respectively, described upper shell and lower house all adopt horn-like or Loadings On Hemispherical Shell shape structure, and adpting flange is set respectively.
Described back-fire relief net is multilayer web-like ripple back-fire relief net.
Described support be a plurality of and described outer casing inner wall coordinate intersect support plate.
The utility model is by arranging the back-fire relief net in the spark arrester upper-lower casing, and be connected with upper-lower casing by support, effectively realized the function that spark arrester is explosion-proof, a board-like support that intersects carries out support limit to the back-fire relief net, the back-fire relief net plays the effect of fire insulation cooling, issuable explosion gas is lowered the temperature and extinguished in back-fire relief net passage of flame, and effectively prevented the generation of tempering phenomenon.This utility structure is reasonable, installation is simple, easy to maintenance, is worthy of popularization.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is structure chart of the present utility model.
The specific embodiment
As shown in Figure 1: a kind of Antiexplosion and fire-stopping unit, comprise the upper shell 1 and the lower house 4 that are fastened and connected, upper shell 1 arranges back-fire relief net 3 with the connecting portion of lower house 4, described back-fire relief net 3 both sides arrange respectively is connected the support 2 that is connected with lower house with upper shell 1, described upper shell 1 all adopts horn-like or Loadings On Hemispherical Shell shape structure with lower house 4, and adpting flange is set respectively.Described back-fire relief net 3 is 6 layers of web-like ripple back-fire relief net.Described support 2 be a plurality of and described outer casing inner wall coordinate intersect support plate.
The utility model is by arranging the back-fire relief net in the spark arrester upper-lower casing, and be connected with upper-lower casing by support, effectively realized the function that spark arrester is explosion-proof, a board-like support that intersects carries out support limit to the back-fire relief net, the back-fire relief net plays the effect of fire insulation cooling, issuable explosion gas is lowered the temperature and extinguished in back-fire relief net passage of flame, and effectively prevented the generation of tempering phenomenon.This utility structure is reasonable, installation is simple, easy to maintenance, is worthy of popularization.
