Abstract
The utility model relates to a welding deformation rigid fastening device is prevented to flexible flange, it includes chassis (1.1), the multichannel fretwork groove of radially evenly arranging (1.3) is seted up to the top surface of chassis (1.1), all is provided with in every fretwork groove (1.3) one slider (1.4), is provided with the screw hole on slider (1.4), the bottom surface of chassis (1.1) is provided with multichannel stiffening rib (1.5), and the position of fretwork groove (1.3) is avoided in stiffening rib (1.5). The utility model has the advantages of simple structure, practice thrift cost, convenient operation, need not carry out unnecessary welding to the flange.
Description
Technical field
The utility model relates to a kind of flexible flange anti-welding deformation rigid fixation means.
Background technology
Flexible flange welding deformation is the key factor affecting flexible flange safety in utilization, the weld seam that steel pipe is connected with flexible flange is welding ring-shaped fillet weld, during welding there is the temperature difference in flange inner circle and cylindrical, therefore expands with heat and contract with cold at end face of flange skewness, causes end face of flange to produce buckling deformation.This deformation cannot be carried out correction process after welding, cannot completely fit, be unsatisfactory for operating specification requirement, there is potential safety hazard after flange docking.Welding rigidly fixed in the past is directly to be welded on slab by flange point, knocks out again or cut off after having welded.The drawback that this mode exists: 1, structure bulky, wastes raw material.2, need to carry out spot welding, add welding cost.3, dismounting inconvenience, needs to polish the spot welding position on flange after demolishing process, inefficient.Therefore a kind of simple in construction, flexible flange anti-welding deformation rigid fixation means cost-effective, easy to operate, that need not flange is carried out unnecessary welding are sought particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that a kind of simple in construction, cost-effective, easy to operate, need not flange is carried out the flexible flange anti-welding deformation rigid fixation means of unnecessary welding.
The purpose of this utility model is achieved in that
A kind of flexible flange anti-welding deformation rigid fixation means, it includes chassis, the end face on described chassis offers the multiple tracks hollow slots of radially uniform layout, a slide block it is provided with in each hollow slots, screwed hole it is provided with on slide block, the bottom surface on described chassis is provided with multiple tracks ribs, and ribs avoids the position of hollow slots.
The middle part on described chassis offers power connector.
The outer end of hollow slots extends to the outward flange on chassis.
Compared with prior art, the beneficial effects of the utility model are:
When the utility model uses, the flexible flange of joint steel pipe is fixed on the chassis face of flexible flange anti-welding deformation rigid fixation means, circle diameter adjusting slider position is arranged according to flexibility method flange aperture, bolt is used to be tightened with slide block by flexible flange, treat after having welded that flexible flange cools down completely to remove again, thus reduce the welding buckling deformation of flexible flange end face.Therefore the utility model have simple in construction, cost-effective, easy to operate, need not advantage that flange is carried out unnecessary welding.

Detailed description of the invention
See Fig. 1 and Fig. 2, a kind of flexible flange anti-welding deformation rigid fixation means that the utility model relates to, it includes chassis 1.1, the middle part on described chassis 1.1 offers power connector 1.2, the end face on described chassis 1.1 offers the multiple tracks hollow slots 1.3 of radially uniform layout, the outer end of hollow slots 1.3 extends to the outward flange on chassis 1.1, the cross section of described hollow slots 1.3 is dovetail groove, a slide block 1.4 it is provided with in each hollow slots 1.3, slide block 1.4 can move along corresponding hollow slots 1.3, it is provided with screwed hole on slide block 1.4, the bottom surface on described chassis 1.1 is provided with multiple tracks ribs 1.5, ribs 1.5 avoids the position of hollow slots 1.3.
During use, the flexible flange 2 of joint steel pipe 3 is fixed on chassis 1.1 end face of flexible flange anti-welding deformation rigid fixation means (being called for short anti-deformation fixing device) 1, arrange circle diameter adjusting slider position according to flexibility method flange aperture, use bolt to be tightened with slide block by flexible flange.
See Fig. 3, use this device that flexible flange is rigidly fixed in welding process, treat after having welded that flexible flange cools down completely and remove again, thus reduce the welding buckling deformation of flexible flange end face.
