Delayed Coking Ball Valve product description

    Delayed Coking Ball Valve适用于Class150~Class1500,PN16~PN100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Delayed Coking Ball 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。Delayed Coking Ball Valve的驱动方式为手动,蜗轮传动,气动或电动。Delayed Coking Ball Valve一般采用法兰连接,也可采用对焊连接。

Delayed Coking Ball valves(Generally flanged connection, but Butt-welding optional) are suitable for using on various kinds of pipeline from Class150 To Class1500, PN16 To PN100 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. Manual/worm gear/pneumatic or electric actuators could be chosen by needs. 

    目前,在国内延迟焦化装置焦炭塔底渣油管线和塔顶油汽管线上大多都是采用高温球阀。在我国各大炼油厂使用的高温球阀绝大多数为进口产品,随着这些产品多年的在线运行已经陆续出现故障,急待全面检修。经对阀门的维护和检修发现,焦炭塔底渣油管线和塔顶油汽管线上所使用的高温球阀结构并不是十分复杂,其制造工艺和parts选材也较为合理。

At present, high temperature ball valve is widely used for domestic delayed coking device, both for the tower botten's residual oil pipe or tower top's oil gas pipe.  The high temperature ball valve used in big oil refineries in our country at this moment are imported, and needed to be overhauled after many years' working.  During the maintenance and overhaul of these valves, the high temperatures used for delay coking device has a not very complex structure and quite reasonable material using and manufacturing  technique.

    Delayed Coking Ball Valve阀杆与球体为一体铸件,通过执行机构转动阀门球体实现对通流介质的通断控制。由于其通流介质一般为渣油或含有焦分的焦化油汽,为了防止Delayed Coking Ball Valve阀门内结焦,采用蒸汽对Delayed Coking Ball Valve内部进行吹扫。蒸汽压力通常在0.8~1.0MPa,温度为250~280℃。

With integrally casted ball & stem, Delayed Coking Ball valve realizes its controlling of cutting off or connecting the flowing of medium by the rotation function of actuator.  As the medium is residue oil or coking oil gas, steam is used to blow the internal surface of delayed coking ball valve to avoid the phenomenon of coking in valve. And the pressure of blowing steam is about 0.8~1.0MPa with temperature of 250~280℃.
