Abstract
The utility model discloses a rubber-lined elastic packing box, which comprises a shell body, an elastic rubber ring and a pressing cover, and is characterized in that a packing cavity in which sealing filling can be arranged into is formed through the shell body, the elastic rubber ring installed in the shell body, a locating ring and the pressing cover. The elastic rubber ring is arranged aroundthe inner wall of the shell body and is fixed in the cavity of the shell body. When the filling is installed into the packing cavity, the pressing cover is tightly screwed to axially contract the filling, since the filling has the plasticity, the filling deforms and generates the radial force, in one aspect, the compact contact is formed between the filling and a shaft, in the other aspect, the filling tightly presses the elastic rubber ring and enables the rubber ring to elastically deform, thereby playing the energy storage function, the elastic deformation of the elastic rubber ring can improve the distribution state of the radial pressing force in the depth direction acted on the surface of the shaft by the filling, and the filling has a certain compensation function during the abrasion along with the increase of the operation time of devices, thereby prolonging the service life and the replacement cycle of sealing filling, reducing the abnormal abrasion between the filling and the shaft, and improving the availability ratio of the sealing filling.
Description
Technical field:
The utility model belongs to shaft sealer, especially belongs to the line with rubber elastic filler case in a kind of material filling type shaft sealer that is applied to equipment such as industry or the reciprocating pump of civilian purposes, reactor, stirrer, rotary pump, valve, wheel stern shaft and oil field sucker rod pumping machine polished rod sealer.
Background technique:
The reciprocating pump of industrial or civilian purposes, reactor, stirrer, rotary pump, valve, the material filling type shaft sealer of wheel equipment such as stern shaft and oil field sucker rod pumping machine polished rod sealer, the general Stuffing box that all adopts rigidity, filler is packed into after the packing cavity, screw gland it is made axial compression, because the plasticity of filler, make it produce radial force, form tight the contact with axle, play the effect of sealing, stop medium to external leakage, but this seal form has its intrinsic shortcoming, the distribution of first filler effect in the radial compaction power on axle surface along the depth direction of packing cavity is uneven, it two is that the radial compaction power size that sealing material acts on axle surface diminishes along with the increase of working time, or the like.
Summary of the invention:
The purpose of this utility model is to provide a kind of can improve the distribution situation that the central stuffing box packing of material filling type shaft sealer acts on the radial compaction power on axle surface, reduce the wearing and tearing of filler and axis abnormality, thereby prolong stuffing box packing working life and replacement cycle, improve the line with rubber elastic filler case of stuffing box packing utilization ratio.
The purpose of this utility model is achieved in that described line with rubber elastic filler case, it mainly is made of housing, elastic rubber ring and gland, the opening of described housing is equipped with the gland that can compress into to the housing inner chamber, polished rod or axle pass from the center hole of housing and gland, and its structural feature can be encircled and is trapped among polished rod or axial packing cavity for be made of can pack into stuffing box packing and stuffing box packing housing, elastic rubber ring and gland; Described elastic rubber ring is looped around the inwall of housing and arranges and be fixed in the inner chamber of housing.
The purpose of this utility model can also be achieved through the following technical solutions, described line with rubber elastic filler case, and its characteristics are that described elastic rubber ring is the elastic rubber ring of being made by macromolecular material with elasticity and stretchability.Described line with rubber elastic filler case, its characteristics are that described elastic rubber ring is installed in the inner chamber of housing by positioning ring.Described line with rubber elastic filler case, its characteristics are that described elastic rubber ring sticks in the inner chamber of housing.Described line with rubber elastic filler case, its characteristics are that directly sulfuration is in the inner chamber of housing.
Elastic rubber ring described in the utility model is the elastic rubber ring with elasticity and stretchability, after filler is packed packing cavity into, screw gland it is made axial compression, because the plasticity of filler, make its distortion and produce radial force, form tight the contact on the one hand with axle, on the other hand, filler extruding elastic rubber ring also makes it to produce resiliently deformable, play the effect of accumulation of energy, the elastic deformation energy of elastic rubber ring improves the distribution situation of filler effect in the radial compaction power on axle surface along the depth direction of packing cavity, and when wearing and tearing along with the increase of operation hours, filler has certain compensating action, thereby prolong stuffing box packing working life and replacement cycle, reduce the wearing and tearing of filler and axis abnormality, improve the utilization ratio of stuffing box packing.The utility model can be widely used in the shaft sealer of equipment such as reciprocating pump, rotary pump, reactor, stirrer, valve, wheel stern shaft and oil-field oil pumper polished rod sealer.
Advantage of the present utility model: elastic rubber ring is installed by inner chamber at the Stuffing box housing, make after filler is packed packing cavity into, screw gland it is made axial compression, because the plasticity of filler, make its distortion and produce radial force, form tight the contact on the one hand with axle, on the other hand, filler extruding elastic rubber ring also makes it to produce resiliently deformable, play the effect of accumulation of energy, the elastic deformation energy of elastic rubber ring improves the distribution situation of filler effect in the radial compaction power on axle surface along the depth direction of packing cavity, and when wearing and tearing along with the increase of operation hours, filler has certain compensating action, thereby prolong stuffing box packing working life and replacement cycle, reduce the wearing and tearing of filler and axis abnormality, improve the utilization ratio of stuffing box packing.Therefore, compare, adopt the material filling type shaft sealer of line with rubber elastic filler case to have bigger superiority, have a extensive future with the material filling type shaft sealer in the traditional rigid filled chamber of employing.
