根据国家标准<石油化工企业设计防火规范>(GB50160-90)之规定,"甲,乙类液体的固定顶罐,应用阻火器和呼吸阀".可见呼吸阀,阻火器是储罐不可缺少的安全设施.它不仅能维持储罐气压平衡,确保储罐在超压或真空时兔遭破坏,且能减少罐内介质的挥发和损耗.
我公司生产的呼吸阀,具有结构紧凑,通气量大,泄漏量小,密封性能好等特点.最近又开发了具有国际先进水准的防爆阻火器呼吸阀(HXF-IZ型),阻火器位于呼吸阀吸入口处,彻底杜绝火源进入呼吸阀壳体内.具有体积小,重量轻,检修,清洗,更换方便等优点.
Flarne Arrsetor and
breather valve should
be equipped on the fop
of tank for type A and
B liquid according to
GB50160-92,"Fire
prevention code of petrol
chermical enterprise
design".Breather
valve and flame arrestor
are indispensable safety
devices.They can not
only remain tank internal
norrnal pressure,but
also prevent over pressure
or vacuum in tank and
reduce liquid volatilization
loss in tank
Our breather valve have
some good features,such
as wo have recently
produced a new flame
breather valve HXF-IZ,which
the flarne arrestor
is installed the suction
end of breather valve,avoiding
flame into the body
of breather valve,It
is charactenized by
better inspection,clear
up and replacement
主要技术参数
适用于各种石油,化工,医药,能源,特殊液体或气体等物料.
