一、进口天然气焊接球阀概述

进口天然气焊接球阀（美国威盾VTON），Gas welded ball valve，也叫天然气全焊接球阀，天然气放散球阀，天然气直埋式球阀，燃气埋地式球阀，是指专用于天然气管道，用来控制天然气的开启和关闭的全焊接球阀，采用20号钢作为阀体，由钢管焊接而成，球垫采用强化聚四氟乙烯，用于天然气管道开关截止的球阀。阀杆采用防爆设计。温度范围：-60-200℃。全焊接球阀广泛应用于天然气、石油、供热、化工及热电管网等长输管线领域。

Gas welded ball valve (VTON), also known as natural gas fully welded ball valve, natural gas release ball valve, natural gas buried ball valve, and gas buried ball valve, refers to a fully welded ball valve specially designed for natural gas pipelines to control the opening and closing of natural gas. It uses 20 # steel as the valve body and is welded from steel pipes. The ball pad is made of reinforced polytetrafluoroethylene, and is used for the opening and closing of natural gas pipelines. The valve stem adopts explosion-proof design. Temperature range: -60-200 ℃. Fully welded ball valves are widely used in long-distance pipeline fields such as natural gas, oil, heating, chemical, and thermal power pipelines.
