Abstract
The invention discloses a flange plate screw hole plugging device, relating to the welding and repairing of screw holes of metal connection flange plates used in the chemical industry. The flange plate screw hole plugging device comprises a flange plate provided with a screw hole; a liner is arranged in the flange plate; a ceramic gasket is arranged at the bottom of the screw hole; and six welding repairing layers are welded in the flange plate. The flange plate screw hole plugging device has the advantage that the flange plate can be welded continuously without being overturned; the welding repair quality is good; and deformation of the welded flange plate can be avoided.
Description
Technical field
The present invention relates to repair by welding to the used metal mounting flange of chemical industry screw.
Background technology
Chemical industry equipment and pipeline connect uses ring flange mostly, and its material is generally carbon steel, but because the particularity of installation site makes the screw after ring flange is processed deviation occur, can't be corresponding with equipment or pipeline, bolt can't normally be penetrated.In order to cut the waste, need weld shutoff to screw, temperature is higher during owing to welding; Often distortion appears in the ring flange after the shutoff, perhaps need not stop to stir ring flange, and operation easier is bigger; Even make in the screw of shutoff and slag inclusion, pore occur, plugging effect is bad.
Summary of the invention
The purpose of this invention is to provide ring flange screw plugging device, it can realize ring flange screw continuous welding shutoff, and the cooling of ring flange when realizing welding, avoids the ring flange distortion of welding.
In order to achieve the above object, the technical scheme of the present invention's employing is:
A kind of ring flange screw plugging device comprises the ring flange that has screw, is provided with lining in the ring flange, it is characterized in that: said screw bottom is provided with ceramic substrate, is welded with 6 layers of soldering layer in the ring flange.
The invention has the beneficial effects as follows: but continuous welding do not need ring flange upset, quality of welding repair is good, avoids the ring flange distortion of welding.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1. ring flange; 2. lining; 3. soldering layer; 4. screw; 5. ceramic substrate.
The specific embodiment
Can be known by accompanying drawing 1, the present invention includes the ring flange 1 that has screw 4, be provided with lining 2 in the ring flange 1, said screw 4 bottoms are provided with ceramic substrate 5, are welded with 6 layers of soldering layer 3 in the ring flange 1.
Welding method is a carbon dioxide gas arc welding, in the welding process, because screw 4 bottoms are provided with ceramic substrate 5; Use the carbon dioxide welding simultaneously; Ring flange 1 is played cooling effect, and need not to overturn repeatedly, make the ring flange 1 after the soldering distortion can not occur.The soldering layer is from upwards 6 layers of soldering altogether of ceramic substrate 5, technological problems such as avoid pore, slag inclusion that common soldering built-up welding produces, splash.Wherein the superiors of soldering slightly exceed screw 4 planes, after polishing, accomplish the shutoff to ring flange 1 screw.
Claims (1)
1. a ring flange screw plugging device comprises the ring flange that has screw, is provided with lining in the ring flange, it is characterized in that: said screw bottom is provided with ceramic substrate, is welded with 6 layers of soldering layer in the ring flange.
