一、进口保温夹套球阀概述

进口保温夹套球阀（美国威盾VTON），Insulation jacket ball valve，也叫夹套保温球阀，缩径保温球阀，全通径保温球阀，是指带有夹套保温层的法兰球阀，通过输入热蒸汽或者导热油到夹套保温层内，对通过阀门的流体进行保温防止凝固和结晶，有效降低管路中介质热量损失的球阀。

美国威盾VTON保温夹套式球阀产品有不锈钢保温球阀，铸钢保温球阀，法兰保温球阀，具有良好的保温保冷特性，且阀门的通径与管径一致，同时又能有效降低管路中介质热量损失。主要用于石油、化工、冶金、制药、食品等各类系统中，以输送常温下会凝固的高粘度介质。

Insulation jacketed ball valve (VTON), also known as jacketed insulated ball valve, reduced diameter insulated ball valve, full bore insulated ball valve, refers to a flanged ball valve with a jacketed insulation layer. By inputting hot steam or thermal oil into the jacketed insulation layer, it insulates the fluid passing through the valve to prevent solidification and crystallization, effectively reducing the heat loss of the medium in the pipeline.

The American Weidun VTON insulated jacket ball valve products include stainless steel insulated ball valves, cast steel insulated ball valves, and flange insulated ball valves, which have good insulation and cooling characteristics, and the valve diameter is consistent with the pipe diameter, while effectively reducing the heat loss of the medium in the pipeline. Mainly used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, and food, to transport high viscosity media that will solidify at room temperature.

二、进口保温夹套球阀特点

1、进口保温夹套球阀采用整体式夹套结构设计，更能均匀地保温、保冷，保温球阀比一般球阀体积更小，重量更轻，且无外漏，密封性能良好。

2、进口保温夹套球阀夹套采用碳素钢管焊接比铸造的更加耐压牢固。 夹套、阀体外侧与夹套接管焊接，允许蒸汽或冷水的最高压力为1MPa。

3、进口保温夹套球阀具有良好的保温、保冷特性，除缩径保温球阀外，阀门的通径和管径一至，介质呈直线流动，阻力小，能有效降低管路中介质热量的损失，因此，对容易凝固、高粘度的液体介质具有优良的性能。

1. The imported insulated jacket ball valve adopts an integral jacket structure design, which can provide more uniform insulation and cooling. The insulated ball valve has a smaller volume, lighter weight, and no external leakage compared to ordinary ball valves, with good sealing performance.

2. The imported insulation jacket ball valve jacket adopts carbon steel pipe welding, which is more pressure resistant and firm than cast. The jacket, valve body outer side and jacket connecting pipe are welded, and the maximum allowable pressure for steam or cold water is 1MPa.

3. The imported insulated jacket ball valve has good insulation and cooling characteristics. In addition to the reduced diameter insulated ball valve, the valve's diameter and pipe diameter are the same, and the medium flows in a straight line with low resistance, which can effectively reduce the heat loss of the medium in the pipeline. Therefore, it has excellent performance for liquid media that are easy to solidify and have high viscosity.
