产品介绍

一、进口低温丝扣止回阀概述

进口低温丝扣止回阀又称低温逆止阀、低温单向阀、低温逆流阀、和低温背压阀，是指采用螺纹的连接方式，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。

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。

Cryogenic thread check valve, also known as cryogenic check valve, cryogenic one-way valve, cryogenic counterflow valve, and cryogenic back pressure valve, refers to the use of threaded connection method, on the cryogenic storage tank or cryogenic pipeline system, relying on the flow of the medium itself The valve automatically opens and closes the valve disc to prevent the backflow of low-temperature media such as liquid oxygen, liquid nitrogen, liquid argon, liquefied natural gas, LO2, LN2, LAR, LNG, etc.

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

三、进口低温丝扣止回阀特点

1、低温止回阀经过低温深冷处理，能耐-196℃低温

2、低温止回阀阀瓣材料经过镀铬或氮化处理，提高阀杆表面硬度，提高填料密封的可靠性。

3、低温止回阀用的垫片具有在常温下、低温状态及温度变化下能可靠密封性和复原性。

4、低温止回阀采用优质的美国威盾的各种零部件材料，能达到流体逆向零泄露，防止倒流。

1. The low-temperature check valve has undergone low-temperature cryogenic treatment and can withstand -196 ℃ low temperature

2. The material of the low-temperature check valve disc is treated with chrome plating or nitriding to improve the surface hardness of the valve stem and enhance the reliability of the packing seal.

3. The gasket used for low-temperature check valves has reliable sealing and recovery properties under normal temperature, low-temperature conditions, and temperature changes.

4. The low-temperature check valve uses high-quality materials from various components of the American shield, which can achieve zero fluid leakage in reverse flow and prevent backflow.
