Pneumatic valve flange sealing butterfly triple eccentric multi-layered structure characteristics and working principle

flange triple eccentric multi-level hard seal butterfly pneumatic valve. Three partial hardness sealing flange butterfly pneumatic valve multi-level products for petrochemical, food, pharmaceutical, textile, papermaking, electric power, sewage treatment, drainage and refining industrial pipes, such as appropriate. In gases, liquids, liquid and powder particles on a pipe or container, as an institution of open and close control of mobile media, etc. Multi-level triple eccentric sealing butterfly pneumatic valve flange can be installed in any place. 。 Flange three eccentric multi-level hard seal butterfly pneumatic valve series, there is a steel plant self-cleaning ability, municipal pipelines, sewer can display a variety of advantages, no maintenance, convenient operation, the seal. The structure characteristics and working principle. Three partial hardness sealing flange butterfly pneumatic valve is the biggest difference between multi-level pneumatic valve, and other: triple eccentric structure design. The rotation of the disc center to the center of the strict design installation eccentric. ℃ pneumatic valve open, even fully open, pneumatic seat and clapper sealing surfaces is non-contact, close the pneumatic valve plate and seat stem cells to swing and prejudices, airtight seal face them. Therefore, opening and closing of small procedures, no wear, prolong the service life of the pneumatic valve. 。 The butterfly with embedded o-ring or pneumatic valve washer, fluorine rubber and plastic forming sealing. Therefore, temperature and abrasion automatic compensation function, ensure no leakage butterfly pneumatic valve closed. 。 Pneumatic seat sealing tube when the tank pressure of the fluid of the incoming letter because Posson make contribution to the principles of action, make the medium pressure pipe seal and o-ring, the power of expansive force will leave pneumatic valve sealing seat face on the CD. This unique structure can increase the line pressure sealing of sealing force. 。 Pneumatic valve seat can be fine-tuning. After years of using pneumatic valve number, when the seal leakage in own, unable to open the case by adjusting the pressure of the pneumatic valve screw seal ring, the adjustment to the direction of the big small dish, can be compensated, and the same as the new pneumatic valve sealing performance. 。 Three flange multi-level manual in addition to covering the eccentric hard sealing butterfly pneumatic valve series, the device can still use pneumatic or electric actuator with a manual adjustment pneumatic valve, pneumatic pneumatic valve ( Feedback signal power can be set up and stretch the locator) And electric pneumatic valve, tee six big series category.
