Features of Imported Eccentric Hemispherical Valves
The product features of imported eccentric hemisphere valves are as follows:
1. Its structure uses the eccentric fitting principle to achieve the purpose of locking, adjusting and closing through the transmission mechanism. The sealing pair is a metal surface ring with hard surface contact seal. When the double eccentric structure is opened, the valve core is located in the ball chamber, the flow section is large, and the valve core is not washed when it is closed. When it is opened, the spherical surface of the valve core is gradually along the valve seat, reliably removing the scaling obstacles, Reliable sealing. It is especially good for the mixed flow transportation of two-phase mixed flow, which is easy to scale and precipitate solids.
2. The hemispherical bimetal of the valve is welded with different alloys on the base metal, and the valve seat is also welded with corresponding surfacing after special treatment. The sealing surface is assembled into various types of anti-corrosion, anti-wear, high strength, etc. to meet the needs of different occasions.
3. Tight sealing and zero leakage of harmful gas transmission.
4. The valve core of the sealing pair has a compensation amount. When the valve is worn, it will turn a little when it is closed, which can be reliably sealed, extending the service life. In addition, the user unscrewed the compression nut, and the valve seat can still be used after adjustment or replacement, avoiding the disadvantage of scrapping the whole set after the valve seal fails.
