Abstract
The utility model relates to a kind of antifreeze flange, comprises mounting flange and lower mounting flange, between two lands, arranges jacket pipe, and described lower land is positioned at the entrance point side of this jacket flange; Lower land comprises chassis and shrouding disc, a side end face outwardly offers annular groove on chassis, in this annular groove, is provided with electrical heating wire, and described shrouding disc to be arranged on chassis and to be covered tightly in annular groove by electrical heating wire.By electrical heating wire being arranged in the lower mounting flange of entrance point in jacket flange, thus heat electrical heating wire being heated produce through fluid be passed in the middle part of jacket pipe and outlet end upper mounting flange on, improve the efficiency that freezes of jacket flange.
Description
Technical field
The utility model relates to a kind of antifreeze flange.
Background technique
Flange is used for connection to pipeline, and at some jacket flanges on cryogenic transfer pipes, in the process used, the phenomenon often appear at frosting on flange, freezing, this use to flange exists very large potential safety hazard, easily makes flange become fragile, easily broken.
People expected arranging electrical heating wire on jacket flange afterwards, but arranging of electrical heating wire is all arranged on jacket pipe, that is be the middle part being arranged on jacket flange, although the setting of this structure also can play the effect of freezing to flange, but the place of Shortcomings, because motor heated filament is mainly arranged on middle part, the heat that electrical heating wire produces is within the regular hour, to the middle part of jacket flange and downstream portion, there is the effect that well freezes, upstream portion for jacket flange can only rely on the heat trnasfer of jacket flange to realize, therefore, slow for freezing of jacket flange upstream.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of antifreeze flange, solves conventional flange and to freeze slow-footed defect.
The utility model solves the technological scheme that its technical problem adopts: a kind of antifreeze flange, comprises mounting flange and lower mounting flange, between two lands, arrange jacket pipe, and described lower land is positioned at the entrance point side of this jacket flange;
Described lower land comprises chassis and shrouding disc, a side end face outwardly offers annular groove on chassis, in this annular groove, is provided with electrical heating wire, and described shrouding disc to be arranged on chassis and to be covered tightly in annular groove by electrical heating wire.
Further, the upper end of described annular groove is provided with sealing ring pad, described sealing ring pad is pressed on electrical heating wire through shrouding disc.
Further, connected by rubber bolt between described chassis and shrouding disc.
The beneficial effects of the utility model are: by being arranged on by electrical heating wire in the lower mounting flange of entrance point in jacket flange, thus heat electrical heating wire being heated produce through fluid be passed in the middle part of jacket pipe and outlet end upper mounting flange on, improve the efficiency that freezes of jacket flange.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, upper mounting flange, 2, lower mounting flange, 21, chassis, 22, shrouding disc, 3, electrical heating wire, 4, sealing ring pad, 5, jacket pipe.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of antifreeze flange, comprise mounting flange 1 and lower mounting flange 2, arrange jacket pipe 5 between two lands, lower land is positioned at the entrance point side of this jacket flange.
Lower land comprises chassis 21 and shrouding disc 22, a side end face outwardly offers annular groove on chassis 21, is provided with electrical heating wire 3 in this annular groove, and shrouding disc 22 to be arranged on chassis 21 and to be covered tightly in annular groove by electrical heating wire 3.
For improving the sealability of annular groove, the upper end of annular groove is provided with sealing ring pad 4, and sealing ring pad 4 is pressed on electrical heating wire 3 through shrouding disc 22.
Connected by rubber bolt between chassis 21 and shrouding disc 22.Rubber bolt connects the benefit brought, and time land is connected with pipeline by metal bolts instantly, the axial force of rubber bolt can not affect the clamping force between chassis 21 and shrouding disc 22.
By electrical heating wire 3 being arranged in the lower mounting flange 2 of entrance point in jacket flange, thus heat electrical heating wire 3 being heated produce through fluid be passed in the middle part of jacket pipe 5 and outlet end upper mounting flange 1 on, improve the efficiency that freezes of jacket flange.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
