Abstract
The utility model proposes a kind of devices for replacing flange gasket.Stud upper backup pad is coupled with lower supporting plate side for adjustable berth away from entirety, lower supporting plate is limited in upper backup pad by nut by other side bolt in parallel.The utility model, which uses, has right-and-left threaded stud connection upper backup pad and lower supporting plate, and rotation stud can adjust spacing between the two, reduces spacing convenient for nosed and pries open flange gap；Bolt one end is fixed in upper backup pad, and the other end slides in lower supporting plate through-hole, and nut limits in parallel, is increased upper backup pad and lower supporting plate gap, is conveniently replaceable flange gasket；The flange two sides that one group of device is set to various models can be realized into nondestructive replacement flange gasket.It is suitable for being used as a kind of device for replacing flange gasket.
Description
Technical field
The utility model relates to flanges, more particularly to flange gasket.
Background technique
Technical solution used by various model flange replacements at present or installation gasket is: with flat chisel or crowbar along flange
Edge insertion, pry open the distance between two panels flange using the principle of lever, by gasket take out or be added.If pipeline diameter
More than ￠ 200mm, the weight of pipeline is difficult to lever up flange plus the stress of pipeline, crowbar often occurs and is prized curved, flange face
The phenomenon that being destroyed with flange water wave line.If pipeline diameter more than ￠ 300mm, is dragged out if replacing gasket by chain block
Flange, operation is more laborious, causes damage that can not be estimated.
Summary of the invention
In order to the gasket of the various model flanges of not damaged convenient replacing, the utility model provides a kind of replacement flange
The device of gasket.The device expands the gap between two panels flange by upper backup pad and lower supporting plate cooperation, is arranged various
On the outside of the flange of model, not damaged convenient replacing gasket solves the technical issues of flange replacement gasket.
The utility model solves scheme used by technical problem:
Stud upper backup pad is coupled with lower supporting plate side for adjustable berth away from entirety, other side bolt passes through nut
Lower supporting plate is limited in upper backup pad in parallel.
The upper backup pad and lower supporting plate are ipsilateral with radial wedge front end, for prying open flange gap.
The upper backup pad sets that there are two positive internal thread through hole.
Lower supporting plate nosed side is equipped with reversed internal thread through hole, and the other side is equipped with through-hole；Reversed internal screw thread is logical
Hole and the center of another through-hole away from upper backup pad two positive internal thread through hole centers away from identical assembly.
The stud top is equipped with forward screw thread, lower part is equipped with reverse thread, and hexagonal rib body is equipped in the middle part of stud for revolving
Turn stud, stud, which is applied between upper backup pad and lower supporting plate, adjusts spacing.
Described bolt one end is threadedly attached in upper backup pad, and the other end passes through the through-hole of lower supporting plate, and passes through spiral shell
Female parallel limit lower supporting plate.
Good effect has right-and-left threaded stud connection upper backup pad and lower supporting plate since the utility model uses,
Rotation stud can adjust spacing between the two, reduce spacing convenient for nosed and pry open flange gap；Bolt one end exists
Upper backup pad is fixed, and the other end slides in lower supporting plate through-hole, and nut limits in parallel, is increased between upper backup pad and lower supporting plate
Gap is conveniently replaceable flange gasket；The flange two sides that one group of device is set to various models can be realized into nondestructive replacement
Flange gasket.It is suitable for being used as a kind of device for replacing flange gasket.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is utility model works schematic diagram.
In figure, 1. upper backup pads, 2. lower supporting plates, 3. studs, 4. bolts, 5. nuts.
Specific embodiment
According to the figure, stud 3 upper backup pad 1 is coupled with 2 side of lower supporting plate for adjustable berth away from entirety, the other side
Lower supporting plate is limited in upper backup pad by nut 5 by bolt 4 in parallel.
The upper backup pad and lower supporting plate are ipsilateral with radial wedge front end, for prying open flange gap.
The upper backup pad sets that there are two positive internal thread through hole.
Lower supporting plate nosed side is equipped with reversed internal thread through hole, and the other side is equipped with through-hole；Reversed internal screw thread is logical
Hole and the center of another through-hole away from upper backup pad two positive internal thread through hole centers away from identical assembly.
The stud top is equipped with forward screw thread, lower part is equipped with reverse thread, and hexagonal rib body is equipped in the middle part of stud for revolving
Turn stud, stud, which is applied between upper backup pad and lower supporting plate, adjusts spacing.
Described bolt one end is threadedly attached in upper backup pad, and the other end passes through the through-hole of lower supporting plate, and passes through spiral shell
Female parallel limit lower supporting plate.
Working principle:
Stud has positive/negative thread, and rotation stud adjusts the spacing of upper backup pad and lower supporting plate, before being easy to use wedge shape
Pry open flange gap in end.
Bolt one end is fixed, and the other end slides in through-hole, and nut limits in parallel, is increased gap, is conveniently replaceable flange gasket
Piece.
The course of work of the utility model:
The device that two sets are replaced flange gasket is symmetricly set on to the two sides of flange, uses upper backup pad and lower supporting plate respectively
Front end insertion two panels flange two sides between gap, two covering devices install in line.Presetting every set upper backup pad, lower branch
Fagging adjusts the parallel stop nut of stud in parallel, rotates the stud that aperture is adjusted with positive/negative thread, the gap of spreading flange is extremely
Suitable distance, locking nut limit in parallel, that is, can be taken off gasket and replaced.
