product description
\nUses and Features<\/p>\n

Vacuum gate valve and vacuum isolation gate valve have two connection forms: flange and welding. There are two types of driving methods: manual and electric. The valve is suitable for the pipeline with the working temperature \u2264425\u2103 and \u2264550\u2103, and the working medium is water, steam or air.<\/p>\n

It is improved from the ordinary manual gate valve. The difference is that a vacuum sealing ring is added to the packing seal of the vacuum gate valve, which has the function of self-expansion and compression, and has better air sealing performance than the ordinary gate valve. The valve is suitable for working temperature \u2264 425 \u2103 (chrome molybdenum steel NKZ44Y type is \u2264 550 \u2103), the working medium is water, steam or air, as an opening and closing device; especially suitable for thermal power plant steam turbine condensation and vacuum negative pressure system , play the role of vacuum isolation and sealing.<\/p>\n<\/div>\n<\/div>\n

\u2460The packing chamber of vacuum sealing structure is designed to isolate the system from the atmosphere and has good environmental protection performance;
\n\u2461 Material selection, in line with relevant standards, and reliable material quality;
\n\u2462The matching of sealing pairs is reasonable, which improves the sealing performance and has a long service life;
\n\u2463The opening and closing parts adopt two-way elastic sealing of parallel gates, with low friction force, easy opening and closing, convenient maintenance, reliable sealing and high performance;
\n\u2464The valve stem is quenched and tempered with nitriding treatment, which has good corrosion resistance, scratch resistance and wear resistance;
\n\u2465 The flange gasket is made of composite material, with large expansion coefficient and good air tightness, ensuring reliable isolation between the system and the atmosphere.<\/p>\n
