Abstract
A kind of Anti-cracking flange disclosed in the utility model, comprise neck tube and be connected to described neck tube one end and flange plate integrated with described neck tube, the joint of described flange plate and neck tube is provided with a rounding.The beneficial effects of the utility model are: the stress produced after the rounding that the joint of flange plate and neck tube is arranged makes flange and pipeline welding is not easily concentrated on the rounding of flange plate and neck tube joint, but be evenly distributed on the joint of flange plate and neck tube, thus avoid the situation that flange plate and neck tube joint crack.
Description
Technical field
The utility model relates to flange technical field, particularly relates to a kind of Anti-cracking flange.
Background technique
Flange is again flange plate or bead.Flange makes pipe and the interconnective part of pipe, is connected to pipe end.See Fig. 1, what provide in figure is existing flange 10, comprise neck tube 11 and be connected to neck tube 11 one end and flange plate 12 integrated with neck tube 11, flange plate 12 is right-angle structure 13 with the joint of neck tube 11, stress is produced after the other end of neck tube 11 welds with pipeline 20, due to flange plate 12 and the direct organization unbalance stress of the joint of neck tube 11, flange plate 12 easily cracks with the joint of neck tube 11, What is more, flange plate 12 and the generation crack, joint of neck tube 11, have a strong impact on Security and the sealability of pipe fitting connection.
For this reason, applicant carried out useful exploration and trial, have found result of the above problems, technological scheme described below produces under this background.
Model utility content
Technical problem to be solved in the utility model: a kind of Anti-cracking flange is provided for the deficiencies in the prior art.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of Anti-cracking flange, comprise neck tube and be connected to described neck tube one end and flange plate integrated with described neck tube, the joint of described flange plate and neck tube is provided with a rounding.
In a preferred embodiment of the present utility model, the central angle of described rounding is 90 °.
Owing to have employed technological scheme as above, the beneficial effects of the utility model are: the stress produced after the rounding that the joint of flange plate and neck tube is arranged makes flange and pipeline welding is not easily concentrated on the rounding of flange plate and neck tube joint, but be evenly distributed on the joint of flange plate and neck tube, thus avoid the situation that flange plate and neck tube joint crack.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the schematic diagram that existing flange is connected with pipeline.
Fig. 2 is the schematic diagram that the utility model is connected with pipeline.
Fig. 3 is I place's enlarged view of Fig. 2.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 2, a kind of Anti-cracking flange 100 provided in figure, comprise neck tube 110 and flange plate 120, neck tube 110 is one-body molded with flange plate 120, one end 111 of neck tube 110 is connected with flange plate 120, its the other end 112 welds with pipeline 200, see Fig. 3, flange plate 120 is provided with a rounding 130 with the joint of neck tube 110, the stress that such design produces after flange 100 is welded with pipeline 200 is not easily concentrated on flange plate 120 with the rounding 130 of neck tube 110 joint, but be evenly distributed on the joint of flange plate 120 and neck tube 110, thus avoid the situation that flange plate 120 cracks with neck tube 110 joint.The central angle alpha of rounding 130 is preferably selected with 90 °, and stress is uniformly distributed more, and Anti-cracking effect is better.
Crack with the joint of neck tube 110 to prevent flange plate 120 further, an Anti-cracking coating (not shown) is coated with at flange plate 120 and the joint of neck tube 110, this Anti-cracking coating is coated on flange plate 120 with on the rounding 130 of the joint of neck tube 110, the thickness of Anti-cracking coating is 0.2mm ~ 0.5mm, is preferably 0.35mm.
Anti-cracking coating preferably but not being made up of interface transition layer, Anti-cracking extension layer and wear-resisting external protection coating successively from bottom to up of being definitely limited to.Wherein, interface transition layer adopts thermoplastic resin modified thermosetting resin, and form through nanometer particle-modified simultaneously, its proportioning (mass fraction): epoxy resin 100, Polyetherimide 10-25, aromatic amine curing agent 20-35 and nano silicon 2-6, interface transition layer is metal and nonmetallic transition layer, play the interface void rate reduced between anticracking extension layer and the joint of flange plate 120 and neck tube 110, improve the adhesive strength between Anti-cracking extension layer and rounding 130.Anti-cracking extension layer is the composite layer formed after Kafra fiber insulating varnish, its proportioning (mass fraction): blending epoxy 100, Polyetherimide 10-25, aromatic amine curing agent 20-35, nano silicon 2-6, Anti-cracking extension layer prevents Crack Extension object effectively, plays the intensity object of the joint of reinforcing flange dish 120 and neck tube 110 simultaneously.Wear-resisting external protection coating adopts modification to strengthen nylon thermoplastic's plastics, and wear-resisting external protection coating protects Anti-cracking extension layer outer surface from external environment condition physical damnification effectively.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. an Anti-cracking flange, comprise neck tube and be connected to described neck tube one end and flange plate integrated with described neck tube, it is characterized in that, the joint of described flange plate and neck tube is provided with a rounding.
