Abstract
The utility model relates to a flange arc section stress leak stopping clamping apparatus which belongs to a fastening instrument and is composed of a clamping plate, a pressing board and a clamping and fastening bolt. The clamping plate takes the shape of an arc section bow, wherein the camber of the bow has an integrative stiffened plate which forms a letter T with the camber of the bow. The pressing board has two bolt holes, while the clamping and fastening bolt has a screw buckle at one end and a toggle at the other end. The clamping and fastening bolt is arranged at both sides of the clamping plate in the radial direction, and the toggle is jacketed at the two ends of the flange bolt, and the two bolt holes of the pressing board is correspondingly jacketed at the screw buckle ends of two clamping and fastening bolts, and then pressed to the stiffened plate and screwed up with the screw caps; wherein, the foot of the clamping plate is provided with a gasket, while at the bending part the fillers are fed into the needle pores in the radial direction. The utility model has the advantages of simple structure, easy, reliable and safe operation and does not need to shut down the equipment, thus not only can quickly treat with various accidents, but also save time, labor and materials.
Description
Technical field
The utility model belongs to fastened tools, particularly a kind of flange segmental arc pressure sealing jig
Background technology
Connected by numerous flanges on the fluid line in the process units, the flange leakage phenomenon happens occasionally.Common solution is the device shut-down (breakdown) mainteance, and the dismounting flange solves and leaks.This will cause time-consuming, influence device production.Under the non-suspended state of device, it will be very necessary handling leakage.Existing pressure sealing method is that a kind of whole jig is that two semi arches dock into a circumference, wrap in the flange outside, form an enclosed cavity with two flange cracks are common, and in cavity, fill with the fluid sealant filler, seal leakage point, but when flange diameter is big, machining fixture is long in time limit, the cost height, and difficulty is big, and the rigidity of jig is very poor, and sealing effectiveness is difficult for guaranteeing.Also have a kind of scene to beat the way of box, promptly hermetically sealed with can in leak, be with the compacting weldering at the scene, this method is dangerous, very easily causes explosion accidents such as fire.The hermetic injecting glue method of the line with rubber of being exactly steel band is being arranged, and the reliability of its sealing is relatively poor for large diameter flange connects.
Summary of the invention
The utility model is intended to overcome deficiency of the prior art, and a kind of flange segmental arc pressure sealing jig of pressure sealing is provided.
Flange segmental arc pressure sealing jig of the present utility model is made of clamp, pressing plate and fixing bolt.Clamp is that segmental arc is arc, and the back of a bow has all-in-one-piece gusset, the back of a bow to be the T font with gusset, and two bolts hole are arranged on the pressing plate, and an end of fixing bolt has that spiral shell is buckled, the other end has the collar.Fix bolt and be the both sides that radially place clamp, the two ends that cover is located on flange bolt, two bolts hole of pressing plate are enclosed within the corresponding two spiral shell end of threads that fix bolts, are depressed on the gusset, with nut tight.
As further improvement of the utility model, wherein, the sole place of clamp is provided with sealing gasket, radially inserts injection pin hole is arranged at the place of bending over.During use, its arc clamp is buckled in side leak insertion your beautiful writings crack, the cover of fastening bolt is located on the flange bolt, top board is fastening gets final product for band.Pin hole by clamp injects the fluid sealant filler in seal chamber, its pressure sealing effect is better.
The advantage of flange segmental arc pressure sealing card of the present utility model is: simple in structure, easy to operate, safe and reliable, and do not need device to stop work, the processing accident is rapid, saves time, laborsaving economical with materials.
Description of drawings
Figure of description is the structural representation of flange segmental arc pressure sealing jig of the present utility model.
Embodiment
Flange segmental arc pressure sealing jig of the present utility model is made of clamp 1, pressing plate 2 and fixing bolt 3.Wherein, clamp 1 is that segmental arc is arc, and the back of a bow has all-in-one-piece gusset 4, the back of a bow to be the T font with gusset 4, and two bolts hole are arranged on the pressing plate 2, and an end of fixing bolt 3 has that spiral shell is buckled, the other end has the collar 5.Fix bolt 3 and be the both sides that radially place clamp 1, the two ends that the collar 5 is placed in flange bolt 6, two bolts hole of pressing plate 2 are enclosed within the corresponding two spiral shell end of threads that fix bolts 3, are depressed on the gusset 4, with nut 7 tight.The sole place of clamp 1 is provided with sealing gasket 8, radially inserts hand-hole 9 is arranged at the place of bending over.
