902 are coated, and are formed sealant, are effectively overcome the influence of material heating status operating condition, improve the resistance to thermal effect of device
Fruit and sealing effect；
During 2 rotation work of eccentric valve rod, eccentric valve rod 2 and packing ring 301 generate extrusion friction, so that packing ring 301
Axial deformation is generated, when pressure is excessive, so that packing ring 301 reaches deformation limit, to constantly consume inside packing ring 301
Filler, in the continuous consumption process of filler, the pressing force of the filler inside packing ring 301 is also constantly consumed, at this time using pressure
The effect of lid flange 401 and gland stud 402 moves down filler compression bar 405, by the filler inside packing ring 301
It is squeezed, to improve the pressing force of 301 inner stuffing of packing ring, extends the service life of packing ring 301, improve device
Safety.
Finally, it should be noted that being not intended to restrict the invention the foregoing is merely preferred embodiment of the invention, to the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, for those skilled in the art, still can be with
It modifies the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.It is all
Within the spirit and principles in the present invention, any modification, equivalent replacement, improvement and so on should be included in guarantor of the invention
Within the scope of shield.
