Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (sectional view, containing seal ring);
Fig. 2 is schematic diagram after the flange assembling of front and back.
1-seal groove, heat insulation half groove of 2-circular radiating, 3-forward flange, 4-heat radiation detects hole, 5-anti-corrosion pipeline, 6-rear flange, heat insulation half groove of 7-circular radiating, 8-auxiliary seal groove.
Embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
Band has a small-bore anti-corrosion pipe for sealed heat-dissipating heat-insulating structure welding neckflange, comprises anti-corrosion pipeline 5, welding neckflange.Welding neckflange is a pair of hollow disc shape Steel Work, is divided into forward flange 3, rear flange 6, forward flange, rear flange and anti-corrosion pipeline is concentric is installed in respectively on the outer wall of anti-corrosion pipeline two end part.On forward flange, rear flange, be all shaped with heat insulation half groove of heat insulation half groove 2,7, two circular radiating of circular radiating and relatively form complete annular heat radiation heat dam, circular radiating heat dam blocks for distributing the high temperature producing when two pipeline weldings connect; Circular radiating heat dam, the shape such as that its section can be is square, oval, polygonal, the present embodiment is rectangular.Forward flange, the heat insulation half groove inwall end face of its circular radiating is shaped with seal groove 1, and its section of seal groove can be " O " type, square, circular, oval, T-shape etc., and the present embodiment is " O " type; In seal groove, be embedded with seal ring, its section configuration of seal ring is corresponding with seal groove can be " O " type, square, circular, oval, T-shape etc., and the present embodiment is " O " type; Seal ring material is high temperature resistant silica gel, seal ring in closed conduct with being communicated with outside pipeline.Forward flange, the heat insulation half groove sidewall of its circular radiating is shaped with heat radiation and detects hole 4, heat radiation detects hole and is connected with heat insulation half groove of circular radiating, when heat radiation detection eyelet welding connects for distributing high temperature in circular radiating heat dam, after welding for detection of pipeline junction sealing condition.Rear flange, its end face and forward flange seal groove opposite position are shaped with auxiliary seal groove 8, and auxiliary seal groove is Liang Zhi tri-roads, and the present embodiment is twice, and its section is triangle, and auxiliary seal groove is for coordinating in closed conduct and being communicated with outside pipeline with seal ring.
Working principle of the present utility model is:
Welding method: the utility model caliber generally, below 600 millimeters, is applicable to make somebody a mere figurehead with buried, and when buried, advantage is more obvious.When construction, first on request seal ring is inlaid in seal groove, then adopting counterpart machine is forward flange by the front end of a pipeline and to be that rear flange docks fixing in the rear end of another root pipeline, now, heat insulation half groove of circular radiating of front and back flange is just in time to being connected into an annular heat dam completing, seal ring is compressed in seal groove and auxiliary seal groove, thoroughly blocks inside, anti-corrosion pipeline joint and outside being communicated with, and then welds.The high temperature producing when welding, a part detects hole through circular radiating heat dam and heat radiation and is dispersed in air, and because heat dam cross section is larger, quite a few heat is dissipated; Another part is transferred to anti-corrosion pipeline end along circular radiating heat dam outer wall, sidewall through inwall, because transmission distance is far away, the heat that is transferred to anti-corrosion pipeline end greatly reduces, and two temperature transfer point apart from each others, pipe end hot area is large, temperature is not concentrated, and has been not enough to the anticorrosive coat in anti-corrosion pipeline to cause damage.After welding, detect hole with pressure gauge by heat radiation and carry out airtight experiment.In circular radiating heat dam, without filling other materials, assemble easy.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: not departing from the spirit and scope of the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
