一、进口锻钢螺纹截止阀概述

进口锻钢螺纹截止阀（威盾VTON），Forged steel threaded globe valve，也叫锻钢内螺纹截止阀，锻钢外螺纹截止阀，是指采用整体一体式的锻造方式，锻打制造的，采用G螺纹，NPT螺纹或者PT螺纹的连接方式的截止阀，具有耐高压，密封性好的特点的截止阀。适用于钢铁厂、石油、化工、煤气、锅炉、造纸、纺织、医药、食品、船舶、供排水、能源、多晶硅、电力等行业工业管道，用于截断或接通管路中的介质，选用不同的材质，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。A105截止阀流体阻力小，适用的压力、温度范围大，介质流动方向不受限制，密封性能良好。

Forged steel threaded globe valve (VTON), also known as forged steel internal threaded globe valve or forged steel external threaded globe valve, refers to a globe valve that uses an integral forging method, forging manufacturing, and connection methods of G thread, NPT thread, or PT thread. It has the characteristics of high pressure resistance and good sealing. Suitable for industrial pipelines in industries such as steel mills, petroleum, chemical, gas, boilers, papermaking, textiles, pharmaceuticals, food, ships, water supply and drainage, energy, polycrystalline silicon, and electricity. Used to cut off or connect media in pipelines, different materials are selected, and can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, etc. A105 globe valve has low fluid resistance, a wide range of applicable pressure and temperature, unrestricted medium flow direction, and good sealing performance.

三、进口锻钢螺纹截止阀特征：

1、结构紧凑、性能可靠、外观精美。

2、采用A105阀体，密封环为聚四氟乙烯工程

3、塑料，耐高压、密封性好，手把搬动灵活舒适。

4、阀芯、阀座密封面经过淬火，在高温、高压下不易磨损、擦伤，密封性好，寿命长。

5、阀盖设计有二个90°密封锥面，锥面一与密封圈组合行成双重密封防止流体外漏；

6、阀门全开时，锥面二与阀杆上锥面楔合，阻止介质流向填料。

1. Compact structure, reliable performance, and exquisite appearance.

2. Adopting A105 valve body and sealing ring made of polytetrafluoroethylene engineering

3. Plastic, resistant to high pressure, good sealing, and flexible and comfortable handling.

4. The sealing surface of the valve core and valve seat is quenched, which is not easy to wear or scratch under high temperature and pressure, has good sealing performance, and a long service life.

5. The valve cover is designed with two 90 ° sealing conical surfaces, and the conical surface is combined with the sealing ring to form a double seal to prevent fluid leakage;

6. When the valve is fully open, cone surface two wedges with the cone surface on the valve stem to prevent the medium from flowing towards the packing.
