产品介绍

一、进口液氩止回阀介绍

进口液氩止回阀Liquid argon check valve又称低温逆止阀、低温单向阀、低温逆流阀、和低温背压阀，是指采用经过低温深冷的不锈钢材质，在低温贮槽上或者低温管道系统，依靠介质本身流动而自动开、闭阀瓣，防止低温介质液氧，液氮，液氩，液化天然气，LO2、LN2、LAR、LNG等倒流的阀门。

液氩纯度99.9995%，微溶于水，熔点为-189.2℃，沸点为-185.7℃，临界温度为-122.3℃，临界压力为4.86MPa，燃烧性能为不可燃，遇高热，容器内压增大，有爆炸的危险。

美国威盾VTON低温止回阀结构紧凑、体积小、重量轻，防止倒流零泄露，稳定性好。

美国威盾VTON低温止回阀主要产品有进口液氩止回阀，进口低温单向阀，进口低温逆止阀，进口液氩止回阀，进口低温焊接止回阀，进口低温法兰止回阀，进口LNG低温止回阀，进口液氮止回阀，进口液氩止回阀，进口液化天然气止回阀，进口低温深冷止回阀等。

Liquid argon check valve, also known as low-temperature check valve, low-temperature one-way valve, low-temperature backflow valve, and low-temperature backpressure valve, refers to a valve made of stainless steel material that has undergone low-temperature deep cooling. It is automatically opened and closed on a low-temperature storage tank or low-temperature pipeline system, relying on the flow of the medium itself to prevent the backflow of low-temperature medium such as liquid oxygen, liquid nitrogen, liquid argon, liquefied natural gas, LO2, LN2, LAR, LNG, etc.

Liquid argon has a purity of 99.9995% and is slightly soluble in water. Its melting point is -189.2 ℃, boiling point is -185.7 ℃, critical temperature is -122.3 ℃, critical pressure is 4.86 MPa, and its combustion performance is non combustible. When exposed to high heat, the pressure inside the container increases, posing a risk of explosion.

The VTON low-temperature check valve has a compact structure, small volume, and light weight, preventing backflow and zero leakage, and good stability.
