Structural Characteristics
Instructions
Packing loading and sealing
the packing place adopts the disc spring loading design, and the long-term sealing is more reliable.
Double group thrust pad design
it can reduce the valve torque, prevent the valve from sticking or crawling after using for a long time, and prolong the service life of the valve.
External leakage point seal
middle flange, lower fixed shaft, upper packing function are hard metal to hard, metal winding pad, O-ring multiple sealing, can also be sealed in the case of fire, the seal is more reliable.
Floating ball design
quantitative floating, not easy to produce valve card, lock phenomenon.
Design of the sphere bow opening
the instantaneous flow of the valve opening is more than 3 times higher compared with the traditional structure, which greatly reduces the scouring damage of the medium to the sphere. At the same time, the existence of the incision increases the thickness of the ball opening and extends the service life of the sphere.
Valve seal
valve stem with low leakage packing (through API 622 certification), labial seal, emergency fat injection seal multiple seal, more reliable seal.
Anti-blowing valve stem
upper packing function structure to prevent the valve stem from blowing out, can realize online replacement of filler.
Valve seat spring pre-tightening seal design
custom spring has the characteristics of small installation space and long service life. Positioning between two sealing rings can not only provide sealing pre-tightening force between the sphere and the valve seat, but also provide sealing force for the valve seat sealing ring.
Block double seal design
use two groups of degreasing graphite sealing rings to seal both ends, which can not only protect the spring, but also achieve double seal.
Unique sphere coating process
the surface of the sphere and the valve seat adopts advanced sputtering coating technology to improve the hardness and wear resistance of the sealing surface, and prevent metal bonding or scratches on the sealing surface due to high frequency friction.
Scraper design on the seat
the scraper structure design is adopted on both sides of the sealing surface, so that the sphere and the seat have the self-cleaning function in the switching process, effectively prevent the accumulation and adhesion of particles between the sphere and the valve seat, and ensure the smooth and continuous valve operation, not stuck.
Ball groove hardening treatment
when the valve is in the high frequency switch, the ball groove connected with the stem will be frequently impacted, resulting in metal fatigue and deformation, and the strength is enhanced by welding hard alloy at the ball mouth, the problem is well solved.
