一、进口电动低温球阀概述

美国威盾VTON电动低温球阀主要适用于介质温度在-40℃～ -196℃等液氮（深冷）介质的低温工况中，为了保证阀门能在低温下安全可靠地运行，阀门零件在精加工前已进行深冷处理，阀盖采用长颈结构，其目的保护填料函的功能，使填料函处于离低温较远的位置，保证填料的密封效果。电动低温球阀常用于低温和深冷介质的管理系统。

VTON electric low-temperature ball valve is mainly suitable for low-temperature working conditions in liquid nitrogen (cryogenic) media with medium temperatures ranging from -40 ℃ to -196 ℃. In order to ensure the safe and reliable operation of the valve at low temperatures, the valve parts have undergone cryogenic treatment before precision machining. The valve cover adopts a long neck structure, which aims to protect the function of the packing box, keep the packing box far away from the low temperature, and ensure the sealing effect of the packing. Electric low-temperature ball valves are commonly used in management systems for low-temperature and cryogenic media.

二、进口电动低温球阀特点

电动低温球阀适用于的各种管路上，用于截断或接通管路中的介质，选用不同材质，可分别适用于不同的温度和介质，最低工作温度为-196℃，使用介质通常为液氦、液氢、液化天然气、液氮、液氧等低温流体。

Electric low-temperature ball valves are suitable for various pipelines, used to cut off or connect the medium in the pipeline. Different materials are selected and can be applied to different temperatures and media. The minimum working temperature is -196 ℃, and the medium used is usually low-temperature fluids such as liquid helium, liquid hydrogen, liquefied natural gas, liquid nitrogen, and liquid oxygen.
