一、进口供热焊接球阀概述

进口供热焊接球阀（威盾VTON），Heat welded ball valve，也叫供暖焊接球阀，供热管网全焊接球阀，供暖管网全焊接球阀，是指一体式的20号钢焊接球阀，用于供热供热的热水管道，对高温热水介质起到开关截止作用的球阀，一体式焊接，密封可靠，安装方便。

美国威盾VTON供热焊接球阀的品质和高性能的稳定性是普通铸钢球阀所无法达到的，其使用寿命远远大于铸钢球阀，进口供热焊接球阀广泛应用于城市燃气、城市供热、石油化工、造船、钢铁、调压站、发电厂等各类管道设备上。全焊接球阀能长期可靠运行使用，不需要维护，安装简单，使阀门的安装别的更为便捷。

Heat welded ball valve (VTON), also known as heating welded ball valve, refers to an integrated 20 steel welded ball valve used in hot water pipelines for heating. It is a ball valve that can switch and cut off high-temperature hot water media. It is welded in one piece, with reliable sealing and easy installation.

The quality and high-performance stability of the American Weidun VTON heating welding ball valve cannot be achieved by ordinary cast steel ball valves, and its service life is much longer than that of cast steel ball valves. Imported heating welding ball valves are widely used in various pipeline equipment such as urban gas, urban heating, petrochemical, shipbuilding, steel, pressure regulating stations, power plants, etc. The fully welded ball valve can operate reliably for a long time without maintenance and is easy to install, making the installation of the valve more convenient.

二、进口供热全焊接球阀特点

一体式全焊接球阀，不会有外部泄漏等现象，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。球体的加工过程有先进的计算机检测仪跟踪检测，所以球体的加工精度高。由于阀体材料跟管道材质一样，不会出现应力不均，也不会由于车辆经过地面时而产生变形，管道耐老化。密封环本体采用含量20%C(碳素)的PTFE材质，保障完全无泄漏(0%)。

The integrated fully welded ball valve will not have external leakage or other phenomena. As the valve seat is 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. The machining process of the sphere is tracked and detected by advanced computer detectors, so the machining accuracy of the sphere is high. Due to the fact that the valve body material is the same as the pipeline material, there will be no uneven stress or deformation caused by vehicles passing through the ground, and the pipeline is resistant to aging. The sealing ring body is made of PTFE material with a content of 20% C (carbon), ensuring complete leakage free (0%).
