Pneumatic double eccentric high performance butterfly valve structure characteristics

pneumatic double eccentric high performance butterfly valve product introduction:
pneumatic double eccentric high-performance pneumatic valve pneumatic butterfly valve plate and seal adopts unique eccentric structure, has a compact structure, good cutting performance, long life and other characteristics of pneumatic double eccentric high-performance butterfly valve with regulation and to cut off the two functions. Pneumatic double eccentric high performance butterfly valve is widely used in metallurgy, chemical industry, electric power, textile, food, medicine, paper and other departments of industrial and municipal engineering, water and other pipe with air or water, sewage, oil liquid, gas, natural gas, steam medium such as cut off or pressure, flow rate control.
pneumatic double eccentric high performance butterfly valve series products are the nominal pressure rating. 、. 、. 、. 、. MPa； Pneumatic valve diameter DN - mm； To adapt to the fluid temperature range - ~ ℃; Metal seal type seal level for Ⅳ or Ⅴ, soft seal type for Ⅳ level ( Bubble level or zero leakage; Flow characteristic is approximate equal percentage.
pneumatic double eccentric high performance butterfly valve product features:
, high-performance adjusting cutting type. Both can adjust pneumatic valve, and can be used for cut off the pneumatic valve.
, two-way sealed type, different from general one-way seal, 'hammer' phenomenon occur even if the backflow medium or can still reliable seal.
and pneumatic valve adopts the integral casting technology, compact structure, small volume, light weight;
, with double eccentric ( AariableEccentricity structure, closing, pneumatic valve plate outward expansion, to achieve the best peripheral sealing state; Opens, pneumatic valve plate and seal out quickly and effectively prevent the sealing ring wear; In this way, both reduced the operation torque, and increase the life of the pneumatic valve.
and seal design, adopted the international advanced technology: ptfe sealing adopts 'lips' form since the seal structure; Hard seal adopts 'U' shaped elastic seal. Long service life and reliable sealing structure. As for what circumstances use soft seal, what circumstances use hard seal, mainly depends on the user's requirements, operating conditions and corrosion resistance requirements.
high-performance butterfly pneumatic valve, pneumatic, double eccentric flow capacity is big, small flow resistance, second only to the o-type ball with diameter of shrinkage capacity pneumatic valve.
high-performance butterfly pneumatic valve, pneumatic, double eccentric circulation of large diameter, flow channel diameter greater than GB regulation of runner diameter. Basic no shrinkage cavity flow, facilitate pipeline cleaning and self-cleaning. Cloudy, low viscosity fluid for suspended particle and fiber media more effective in attached.
no flange clamp, and pipeline connection way. Structure length: soft seal used in GB series ( In ISO series code: hard seal with GB long series ( The ISO series code:. So this kind of pneumatic valve strong universality and interchangeability, in line with international standards.
standard actuators, four categories: pneumatic piston ( ZS, pneumatic diaphragm ( ZM, electric mechanical switch type ( ZA, electric electronic adjusting type ( Lh-zd interchangeable.
