Flange three eccentric multi-level hard sealing butterfly valve - 2014-01-07 16:56:48

1, Flange three eccentric multi-level hard sealing butterfly valve products can be applied in petrochemical, food, pharmaceutical, textile, paper, electricity , sewage treatment, water supply and drainage and smelting and other industrial piping. Pipelines or containers may be in a variety of gases, liquids, semi-fluid and micro- particles as a control on the flow of medium to the opening and closing mechanism . Flange three eccentric multi-level hard sealing butterfly valve can be mounted in any position.

2, Flange three eccentric multi-level hard sealing butterfly valve series , has a certain self-cleaning capacity for steel mills, municipal pipelines, sewers can show a variety of advantages , no maintenance , and good sealing performance , easy operation .

Structural characteristics and role of the principle

1, Flange three eccentric multi-level hard sealing butterfly valve with the other biggest difference is : Three eccentric design structure. Its installation disc center and the center of rotation rigorous design eccentricity . When the valve opens at 10 ℃ even open, valve seat sealing surface and the disc that is in a non- contact state , and when closing the disc with the stem leaving the roundabout and deflected into the hermetic sealing surface of the valve seat . Therefore, due to the small opening and closing process , no wear and extend the life of the valve .

2, Butterfly valve seat with embedded rubber O- ring or gasket and fluorine plastic is combined into a seal. Therefore, the difference in temperature and wear self- compensation function to ensure no leakage butterfly valve is closed .

3, When the fluid pressure in the pipeline valve seat seal incoming mail slot , because Posson's action principle component , the seal force in the pipeline pressure and O -ring expansion force generated by the sealing surface of the valve seat pressed against the disc leaving the valve seal . This unique seal structure with the increase of the line pressure can produce a greater sealing force .

4, The valve seat can be fine-tuned. After the valve using a certain number of years , when their own wear ring leakage , can not open the valve in the case by the adjusting screw the sealing ring to fine-tune the disc pressing direction to the desired size , you can get the compensation and has also the new valve sealing performance.

5, Flange three eccentric multi-level hard sealing butterfly valve series with the exception of the manual device , but still with a pneumatic or electronic device constitutes a manual valve, pneumatic valve ( can be attached electrical position feedback signal and processing home stretch positioner ) and electric butterfly valves , etc. three categories of six series.
