The closing part of the Vacuum globe valve is a valve body, and the valve body rotates around the center line of the valve body to achieve opening and closing. It is suitable for pipelines with working temperature ≤425℃ and ≤550℃, and the working medium is water, steam or air. As an opening and closing device, it is suitable for steam turbine condensation and vacuum negative pressure systems in thermal power plants, and plays the role of vacuum isolation and sealing.
Structural features:
1, The main body of this series of valves adopts casting and forging structure, with parallel double sealing pair semi-forced two-way sealing, sealing surface in place movement and wedge block wedge tight movement step by step action to achieve zero leakage.
2, The sealing surface movement friction force is small, easy to open and close, and the sealing surface wear automatic compensation function.
3, Simple structure, compact, easy maintenance, long service life.
4, The valve cover packing chamber is equipped with a vacuum sealing structure, with self-expanding and pressing effect, and the sealing is sealed with high strength expansion material, so that the system is completely isolated from the atmosphere, with a good system air tightness.
5, This series of valve connection form is divided into flange and welding, driving mode has manual and electric.
