Abstract
For the deficiencies in the prior art, the utility model provides a kind of valve packing structure, is made up of stuffing box, filler and gland, and filler is arranged in stuffing box, and described gland is arranged on above filler; Filler spacer ring is provided with in the middle of filler, this filler spacer ring is hollow structure, seal gease is provided with in described hollow structure, described filler spacer ring inner ring surface is provided with bleeding holes, this structure can well overcome the deficiencies in the prior art, simultaneously good in maintenance " bearing effect " and " labyrinth effect " again at the reliable sealing that ensure that valve rod, ensure that the stabilized seal effect of filler, well avoid that filler is worn, etch, the factor such as aging, dry, temperature impact.
Description
Technical field
This practicability relates to valve technology field, particularly relates to a kind of valve packing structure.
Background technique
Filler loads after packing cavity, makes axial compression through gland screw to it, when axle and filler have relative movement, due to the plasticity of filler, makes its generation radial force, and with axle close contact.Meanwhile, the oiling agent flooded in filler is extruded, between surface of contact, form oil film.Because contact condition is not uniform especially, state that contact position just occurs " boundary lubrication ", is called " bearing effect "; And the recess do not contacted forms little oil groove, there is thicker oil film, irregular labyrinth together with contact position forms with non-contact position, play a part to stop liquid to flow leakage, this claims " labyrinth effect ", gland sealed mechanism that Here it is, obviously, good sealing is to maintain " bearing effect " and " labyrinth effect "; Filler is long for service time, filler in running, be easily worn, etch, the factor such as aging, dry, temperature impact, lose compactness gradually and cause seepage, this phenomenon is comparatively general in stuffing seal.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of valve packing structure, and this structure can well overcome the deficiencies in the prior art.
To achieve these goals, the technological scheme that the utility model provides is as follows: a kind of valve packing structure, is made up of stuffing box, filler and gland, and filler is arranged in stuffing box, and described gland is arranged on above filler; Be provided with filler spacer ring in the middle of filler, this filler spacer ring is hollow structure, is provided with seal gease in described hollow structure, and described filler spacer ring inner ring surface is provided with bleeding holes.
The beneficial effects of the utility model are designed by said structure, filler is when using certain hour, the filler spacer ring in filler neutral position is arranged on by the extruding of gland, the seal gease being arranged on filler spacer ring inside oozes out in the bleeding holes of filler spacer ring, simultaneously good in maintenance " bearing effect " and " labyrinth effect " again at the reliable sealing that ensure that valve rod, ensure that the stabilized seal effect of filler, well avoid that filler is worn, etch, the factor such as aging, dry, temperature impact.
