一、进口全通径焊接球阀概述

进口全通径焊接球阀（美国威盾VTON），Full bore welded ball valve，也叫全流通焊接球阀。全通径全焊接球阀，通径全焊接球阀，涡轮全通径焊接球阀，是指采用全通径的结构形式，采用碳钢无缝钢管压制成型整体式，以不锈钢为球体，采用全焊接的连接方式，采用碳强化PTFE斜面弹性密封圈负压在球面上，使密封达到零泄漏的球阀。应用于天然气、石油、供热、化工及热电管网等长输管线领域。

Full bore welded ball valve (VTON), also known as full bore welded ball valve. Full bore all welded ball valve, full bore all welded ball valve, turbine all bore all welded ball valve refer to ball valves that adopt a full bore structural form, use carbon steel seamless steel pipe to press and form an integral type, use stainless steel as the sphere, adopt a fully welded connection method, and use carbon reinforced PTFE inclined surface elastic sealing ring negative pressure on the sphere to achieve zero leakage sealing. Applied in long-distance pipeline fields such as natural gas, oil, heating, chemical and thermal power pipelines.

二、进口全通径焊接球阀产品特性
1、钢制球阀，带有轴向负载的焊接端
2、不需要维护，调整及润滑，易于安装，在低运行费用下长期可靠运行；
3、阀杆可以加长、易于保温；
4、操作手柄可以拆下，换向安装；
5、阀体不含沉重且不可靠的铸件；
6、安装调节机构，非常简便。

7、全通径结构，流量大，无流量损失，压损小，流通顺畅。
