API Forged Steel Cryogenic Lift Check Valve

     CHAODA group专业研制生产API Forged Steel Cryogenic Lift Check Valve等 valve products, CHAODA生产的API Forged Steel Cryogenic Lift Check Valve的结构一般与截止阀相似,其阀瓣沿着通道中以线作升降运动,动作可靠,但流体阻力较大,不锈钢低温止回阀适用于轻小口径的场合。低温升降式止回阀可直通式和立式两种。直通式升降止回阀一般只能安装在水平管路,而立式升降止回阀一般就安装在垂直管路。

CHAODA Valves Group is specialized in manufacturing API Forged Steel Cryogenic Lift Check valve. The structure of Cryogenic Lift check valve is very similar with Globe valve with the disc doing up and down movement during valve's operation. It has a reliable sealing but with relatively high flowing resistance. Stainless steel Cryogenic Check valve is suitable for small size area. Cryogenic Lift check valve could be in through type or vertical type. The through type lift check valve could only be installed on horizontal pipeline, while the vertical type lift check valve is usually on vertical pipeline.

    API Forged Steel Cryogenic Lift Check Valve主要适用于液态低温介质如乙烯,液氧,液氢,液化天然气,液化石油产品等工况,该类型介质易燃易爆。锻钢低温升降式止回阀,是自动阀门,靠介质本身的力来控制止回阀的启闭,因此不用长颈结构。在低温升降式止回阀加工过程中会有一道低温处理工序,将粗加工的parts置于冷却介质中数小时(2-8小时),以释放应力,确保 material的低温性能。

API Forged steel cryogenic lift check valve is used for inflammable and explosive liquid medium such as ethylene, liquid oxygen, liquid hydrogen, LNG, liquefied petroleum product and etc. As forged steel cryogenic lift check valve is an automatic valve realizing the opening and closing all by the force of mediu, so there is no need of long neck structure. All the components of cryogenic lift check valve would be immersed in cooling medium for 2-8 hours after raw machining to release the stress and ensure its cryogenic property.

API Forged Steel Cryogenic Lift Check Valve product description

    API Forged Steel Cryogenic Lift Check Valve适用于Class150~Class1500,PN16~PN160的各种管路上,用于截断或接通管路中的介质。选用不同的材质,CHAODA group的API Forged Steel Cryogenic Lift Check Valve可分别适用于水,蒸汽,油品,硝酸,醋酸,氧化性介质,尿素等多种介质。

API Forged Steel Cryogenic Lift Check valves are suitable for use on various kinds of pipeline from Class150 To Class1500, PN16 To PN250 to cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. 

    当介质由API Forged Steel Cryogenic Lift Check Valve阀体箭头所示流向进入阀体,介质的压力作用在低温升降式止回阀阀瓣上产生向上的推力,当介质推力大于阀瓣重力时,钢制低温止回阀打开。当低温升降式止回阀阀后介质压力作用在阀瓣上的力加上阀瓣自身重力大于阀前压力作用在阀瓣上的力时,阀门关闭,阻止介质倒流。

Working Principle of API Forged Steel Cryogenic Lift Check Valve:  When the medium passing through the valve from the inlet port, the valve would open if the pressure force of medium exceeds the gravity of disc. However, when the pressure force of backflow medium plus the force of disc's gravity is bigger than the medium force from the inlet side, the valve would close itself to prevent the backflow.
