优质进口低温止回阀品牌推荐德国洛克

一、进口低温止回阀描述：

德国LOCKE洛克进口低温止回阀是指用于低温液体（主要包括液氧、液氮、液氩、液态烃和液化天然气等）贮运设备的管理系统中防止低温介质倒流的阀门。主要应用于气体液化设备、空分设备；天然气液化、储运设备；液态氧、氮、氩、氢、二氧化碳低温贮槽及槽车；变压吸附制氧、氮设备。广泛应用于能源、石化、冶金、航天、核工业、铁道等行业等行业。

The imported low temperature check valve of Locke lock in Germany refers to the valve used in the management system of low temperature liquid (mainly including liquid oxygen, liquid nitrogen, liquid argon, liquid hydrocarbon and liquefied natural gas) storage and transportation equipment to prevent the backflow of low temperature medium. It is mainly used in gas liquefaction equipment, air separation equipment, natural gas liquefaction, storage and transportation equipment, liquid oxygen, nitrogen, argon, hydrogen, carbon dioxide low temperature storage tank and tank car, PSA oxygen and nitrogen production equipment. Widely used in energy, petrochemical, metallurgy, aerospace, nuclear industry, railway and other industries.
