Abstract
The utility model relates to a metal packing ring technical field just discloses a novel packing ring structure of anti deformation of self-expanding, including last packing ring and lower packing ring, it is equipped with sealed the pad to go up the cover between packing ring and the lower packing ring, the bottom of going up the packing ring is provided with the card, the inside of lower packing ring is provided with the draw-in groove with the card adaptation. This from anti novel packing ring structure of deformation that expands, can carry out spacing fixed to last packing ring and lower gasket through the draw-in groove when can supporting the buffering to last packing ring through the card, make the packing ring form the auto-lock after screwing up, with the inside connection leakproofness of reinforcing, cooperation through the locating hole of reference column is used, make and have the location between last packing ring and the lower gasket, and then can not produce the rotation between last packing ring and the lower gasket when the packing ring is fixed, in order to prevent to lead to the fact wearing and tearing to sealed the pad, go up packing ring and lower gasket simultaneously and adopt the disconnect-type design, can change alone when damaging, resources are saved relatively.
Description
Technical Field
The utility model relates to a metal packing ring technical field specifically is a novel packing ring structure of anti deformation of self-expanding.
Background
Most of the existing partial metal gaskets adopt an integrated structural design, the whole gasket needs to be replaced after the gasket is partially worn, resources are wasted, and meanwhile, after the gasket is fixed, the gasket can be stressed to deform, and the sealing performance of the joint of the gasket cannot be guaranteed.
SUMMERY OF THE UTILITY MODEL
The utility model provides a novel packing ring structure of anti deformation of self-expanding, to the not enough of background art, has solved the problem that above-mentioned background art provided.
The utility model provides a following technical scheme: the utility model provides a novel packing ring structure of anti deformation of self-expanding, includes packing ring and lower packing ring, it is equipped with sealed the pad to go up the cover between packing ring and the lower packing ring, the bottom of going up the packing ring is provided with the card, the inside of packing ring is provided with the draw-in groove with the card adaptation down, the top of packing ring is provided with the reference column of suit in last packing ring down.
Preferably, the inner side of the upper gasket is provided with a positioning hole matched with the positioning column.
Preferably, the number of the cards is eight, and the eight cards are annularly and equidistantly distributed on the upper gasket.
Preferably, the number of the clamping grooves is eight, and the eight clamping grooves and the cards are distributed in a one-to-one correspondence mode.
Preferably, the number of the positioning columns is eight, and the eight positioning columns are annularly and equidistantly distributed on the lower gasket.
The utility model discloses possess following beneficial effect:
1. this from anti deformation's of inflation novel packing ring structure can carry out spacing fixed through the draw-in groove to last packing ring and lower packing ring when can supporting the buffering to last packing ring through the card for can form the auto-lock after the packing ring is screwed up, with the inside connection leakproofness of reinforcing.
2. This anti novel packing ring structure of deformation from inflation uses through the cooperation of the locating hole of reference column for there is the location between last packing ring and the lower packing ring, and then can not produce the rotation between last packing ring and the lower packing ring when the packing ring is fixed, in order to prevent to seal up and lead to the fact wearing and tearing, goes up packing ring and lower packing ring simultaneously and adopts the disconnect-type design, can change relatively resources are saved alone when damaging.
