ZFQ-1-type weather proof Fire breathing valve
Product Name:
ZFQ-1-type weather proof Fire breathing valve
Description:

ZFQ-1 型全天候防爆阻火呼吸阀

                                      
防爆阻火呼吸阀概述:
ZFQ-1 型全天候防爆阻火呼吸阀。该产品集阻火器与呼吸阀为一体,其新颖的结构为国内首创。它是石化储罐必备的新型安全设备,其最大优点是阻火呼吸性能好,重量轻,维修方便。该产品适用于储存内点低于 28 ℃的甲类油品和闪点低于 60 ℃的乙类油品,如汽油、笨、甲笨、煤油、轻柴油、机油、原油等油品及性质相同的化工产品储罐使用,它在 -35 ℃ -60 ℃的温度环境中正常工作。
防爆阻火呼吸阀性能及特点:
壳体选用铸钢和铝合金,耐腐蚀性好;
波纹阻火层采用不锈钢材料,阻火性能好,耐腐蚀性能好;
结构简单,易检修,安全方便;
防爆阻火呼吸阀维护与保养:
为了呼吸阀使用安全,应在 3-6 个月内定期将波纹阻火层拆下,清洗干净,保证阻火层上每个孔畅通,防止堵塞,确保安全正常使用。
定期检查通风气正、负阀盘动作是否灵活,导杆及阀盘接触密封面有无损坏,如有损坏应立即调换。 在检查维护重新安装时,应保证阀内各结合面严密配合,阀盘升降灵活。 新阀启用时,应安装前清除阀盘间的防震物,否则呼吸阀将失灵。
