Independent seat: The seat is of an independent quick-change structure. The seat and the sealing ring are removable and interchangeable. Compared with the integral seat, the deformation ratio of the independent seat is closer to that of the sealing ring and therefore, the sealing performance is more reliable.

Combined packing design:Special dedicated combined packing is adopted. It is resistant to high temperature ( 6 5 0 ^ { \circ } { ~ C ~ } ) and oxidation, composed of inorganic salt and graphite, sealed in multiple layers to prevent leakage of the medium, and meets the requirements of TU-LUFT

Dynamic disc spring-loaded compensation structure: The packing system is of a dynamic disc spring-loaded compensation structure. The packing box bore of the valve body is subjected to roll extrusion, and the stem to ultrasonic vibration. In this way, it ensures that the packing will absolutely not leak and meets the requirements of TA-LUFT standard. In addition, the structure can automatically compensate for the pretightening force of the packing and extend its maintenance cycle.

All-metal sealing pair: The sealing pair is of an all-metal structure. It is intrinsically fireproof and anti-static. The surfacing of the sealing face does not contain any soft materials such as asbestos and graphite. Therefore, it will not cause pollution to the medium. The sealing face is in uniform and reliable contact and provides excellent sealing performance. The sealing face is also subjected to surfacing with hard alloy and has wear and corrosion resistance and a long service life.

Triple-offset structure: The all-metal butterfly valves are of a triple-offset structure. They are suitable for applications requiring tight cutoff in complex operating conditions such as high temperature and high pressure. There is no friction during valve opening and closing, so the opening torque is small. Torque sealing is adopted: The greater the medium force is, the better the sealing performance will be.

Anti-blowout stem: The design of stepped structure can effectively prevent blowout of the stem, greatly ensuring the safety of the valve.The integral stem is used and made of highstrength stainless steel, so that the valve can withstand a large allowable differential pressure.

Triple-offset structure: The all-metal butterfly valves are of a triple-offset structure. They are suitable for applications requiring tight cutoff in complex operating conditions such as high temperature and high pressure. There is no friction during valve opening and closing, so the opening torque is small. Torque sealing is adopted: The greater the medium force is, the better the sealing performance will be.

A cylindrical pin offset structure is adopted for the transmission between stem and disc. It can prevent the reduction of stem strength due to drilling, indirectly improve the shear strength of cylindrical pin, and further improve the safety and reliability of the valve.

Principle

Dual-eccentric design: axial distance offset and angle offset can make the disk leaving the seat ring quickly under opening valve, which can eliminate unnecessary excessive pressing and abrasion, so as to reduce torque and abrasion and prolong service life.

Back-up ring and TYPE-u metal seat ring: the Back-up ring on the back of seat ring of soft sealed butterfly valve can avoid the inner leakage and compensate the energy reduced by abrasion so as to prolong the service life of seat ring. Type-U metal seat ring of metal sealed butterfly forms a special line-sealed with disc to prevent the sealing face from particles damaging, meanwhile type u seat ring is flexible to guarantee leakage and service life, which is applicable to the service conditions with high temperature.

'Circular sphere"sealing: meshing angle will be Iarger to make the disc squeezing into g seat ring more easily, so as to reduce abrasion and prolong service life.

Stem sealing: High temperature resistant non-metallic material can prevent the particles from entering into bearing, so as to avoid locked or jammed.
