上海姚阀阀门厂——呼吸阀——JAV夹套保温呼吸阀,信息如下,欢迎订购。
呼吸阀是安装在固定顶储罐上的通风装置,可减少油品蒸发损耗,控制储罐压力平衡。根据国家标准《石油化工企业设计防火规范》(GB50160-92)之规定:“甲、乙类液体的固定顶罐,应设阻火器和呼吸阀”。可见呼吸阀、阻火器是储罐必不可少的安全设施。
我厂生产的系列呼吸阀,根据不同介质环境的需求,可分为呼吸阀及呼吸阀与阻火器、阻火层的联合体式的阻火呼吸阀,彻底杜绝火源进入呼吸阀壳内,并且根据特殊环境的需求,分为单呼阀、单吸阀、带双接管呼吸阀等,可满足各种不同需求。具有结构紧凑、通气量大、泄漏量小、密封性能好,检修、清洗、更换方便等优点。

制造、检测标准:按石油储罐呼吸阀SY7511-96、石油储罐阻火器阻火性能和试验方法GB5908-86等标准进行制造和验收,或客户指定标准。
呼吸阀性能及特点:
呼吸阀的阀体能承受0.2Mpa的水压,无渗透和变形现象。
呼吸阀耐低温性能在空气相对湿度大于70%,最低温度为-30℃时,经过24小时的冷冻后,其阀盘开启压力符合工作压力要求,(允许压差正负20pa)。
呼吸阀的阀盘部件动作时,灵敏度高,动作完成后,保证密封。
呼吸阀阀内留有足够的空间,保证储罐的通气量。
呼吸阀没达到工作压力以前:公称通径≤150mm,其泄漏量≤0.04m3/h;
公称通径≥220mm,其泄漏量≤0.4m3/h;
当呼吸阀达到了工作压力以后:阀盘立即开启,保证储罐正常的通气要求。
