一种止回阀型阻火器
本技术涉及阻火器
,具体涉及一种止回阀型阻火器。
技术介绍
阻火器是用来阻止易燃气体、液体的火焰蔓延和防止回火而引起爆炸的安全装置。通常装在输送或排放易燃易爆气体的储罐和管线上。广泛应用于食品、酿酒、饮料、乳制品、精细化工制药、生物发酵工程、酒精管道等易燃易爆气体液体车间,保证管道和车间的安全性,这样的阻火器在阻火芯吸收热量后,阻火芯的温度不能快速降温,影响阻火效果,且阻火芯只有一层,阻火效果部完全,而且安装外壳体积大,安装空间占用过大。
技术实现思路
本技术的目的是提供一种止回阀型阻火器,该阻火器阻火芯降温快,提升阻火效果,占用体积小。为了实现上述目的,本技术采用的技术方案是:一种止回阀型阻火器,包括止回阀体、双层阻火芯,所述止回阀体的中部设有腔室,所述止回阀体的左端设有入气口、所述止回阀体的右端设有出气口,所述双层阻火芯竖直设置在止回阀体内部的中部,所述双层阻火芯由第一阻火芯、第二阻火芯组成,所述第一阻火芯设置在第二阻火芯的左侧,所述双层阻火芯上设有横截面为三角形的通孔,所述第一阻火芯、第二阻火芯的上端设有一导热柱,所述导热柱的下端设有一贯串 ...
