Cryogenic Globe Valve

     CHAODA group专业研制生产Cryogenic Globe Valve等 valve products, CHAODA生产的Cryogenic Globe Valve has the features of Good sealing, reliable, safety and long life span.阀门行业讲到的Cryogenic Globe Valve,多指上盖加长径截止阀。由于Cryogenic Globe Valve的使用工况在-100℃以下,阀瓣和阀体在喷焊硬质合金后,要进行深冷处理。Cryogenic Globe Valve样机的阀体与阀瓣粗加工后,浸在-196℃的液氮中保冷2小时,然后取出自然处理。另外,阀杆,长颈阀盖,螺纹紧固件等主要部件在精加工前均进行深冷处理。

CHAODA Valves Group is specialized in manufacturing Cryogenic Cast Steel Globe valve with following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc. The cryogenic globe valve we mention in valve industry refers to the extended neck type globe valve. The sealing face needs to be cryogenic treated after being welded with Hard alloy as the cryogenic globe valve works under -100℃. After raw machining, the body and disc shall be treated in liquid nitrogen(-196℃) for 2 hours and then taken out for natural treatment. Moreover, stem, extended neck bonnet, threaded fastenings and other important components shall also be cryogenic treated before finish machining.

    长颈阀盖,也就是上面说的上盖加长径。颈部加长的原因是,截止阀适合作为液氮等低温介质的输送管道中切断或调节以及节流用,如果要保持上盖的密封圈能正常密封,必须延长上盖的颈部,使阀体中的较低温度不会影响到Cryogenic Globe Valve上盖的密封。

Bonnet with extended neck is used for Cryogenic valve to cut off, connect or regulate the flowing low temperature medium such as liquefied nitrogen. This type of extended neck structure is designed to ensure the sealing performance of packing part would not be affected by the very low temperature medium.

Cryogenic Globe Valve product description

    Cryogenic Globe 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Cryogenic Globe 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。Cryogenic Globe Valve的驱动方式为手动,蜗轮传动,气动或电动。Cryogenic Globe Valve一般采用法兰连接,也可采用对焊连接。

Cryogenic Cast Steel Globe valves(Generally flanged connection, but Butt-welding optional) are suitable for use on various kinds of pipeline from Class150 To Class1500, PN16 To PN160 to cut off or connect the following 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. Manual/bevel gear/pneumatic or electric actuators could be chosen by needs.

    CHAODA GROUP WENZHOU E-BUSINESS CO.,LTD.is wholly owned subsidiary by Chaoda Group,Professional sales CHAODA group products,CHAODA valve products。CHAODA valves won the reputations of Zhejiang Famous Trademark,Zhejiang Famous Brand,Zhejiang Famous Exporting Brand and also enjoys prizes of 101 National Patent。

    手动钢制Cryogenic Globe Valve采用阀瓣与阀座接触的锥面密封结构,密封副设计成金属对金属的硬密封形式,阀座设计在阀体上,和阀体组成一体结构。为保证Cryogenic Globe Valve的可靠密封,在阀瓣和阀体密封面上喷焊硬质合金。

Manual steel Cryogenic Globe valve has the cone shaped metal to metal sealing face. Integral seat is designed on the valve's body. Hard alloy is deposited onto the sealing face of disc & body to achieve a reliable performance. 

    经过低温试验及涂层力学性能试验,证明喷涂后硬度增加,低温环境耐磨性能良好,促进阀门在低温环境的可靠密封。经过查阅资料和实验应用,我们采用等离子喷焊技术对阀体密封面喷焊StelliteNo6合金,对阀瓣密封面喷焊StelliteNo12合金,厚度≥1mm。经过喷焊工艺处理,附着StelliteNo12合金的阀瓣密封面的硬度较附着StelliteNo6合金的阀体密封面的硬度大,有利于截止阀的密封效果。

Low temperature treatment and mechanical property test shall be done for welded coating to ensure enough hardness and good wear-resistance and reliable sealing performance under cryogenic condition. Stellite No. 6 alloy is plasma sprayed onto the seat surface and Stellite No.12 on disc's surface with at least 1mm thickness. The hardness difference between them(Stellite No. 12 has the larger hardness value) ensures the good sealing performance of Cryogenic Globe valve.
