一、进口煤气焊接球阀概述

进口煤气焊接球阀（美国威盾VTON），Gas welded ball valve，也叫煤气全焊接球阀，煤气埋地式球阀，煤气直埋式球阀，煤气管网球阀，是指专用于控制各种工业煤气的启闭的球阀，采用一体式全焊接球阀，不会有外部泄漏等现象，用于工业煤气输入或者输出管线的球阀。由于阀座是由碳化特氟隆密封环及咖弹簧构成的，所以对压力和温度的变化适应能力强，在标注压力和温度范围内不会产生任何泄滑。

Gas welded ball valve (VTON), also known as gas fully welded ball valve, gas buried ball valve, gas buried ball valve, and gas pipeline ball valve, refers to a ball valve specially designed to control the opening and closing of various industrial gases. It adopts an integrated fully welded ball valve and will not have external leakage. It is used as a ball valve for industrial gas input or output pipelines. Due to the valve seat being composed of carbonized PTFE sealing rings and coffee springs, it has strong adaptability to pressure and temperature changes, and will not produce any leakage within the marked pressure and temperature range.
