Abstract
The utility model discloses a practical slip-on hubbed flange. The practical slip-on hubbed flange comprises a flange plate, a neck tube and a lug. The neck tube is formed in the flange plate. The lug is arranged at the bottom of the flange plate. The flange plate, the neck tube and the lug are provided with a same inner hole. The neck tube and the lug are respectively perpendicular to the flange plate. Fillets are formed at connecting positions between the neck tube and the flange plate. Outer diameter of the neck tube is smaller than that of the lug. Mounting holes are formed between the outer diameter of the lug and outer diameter of the flange plate and used for fixing bolts. The flange plate, the neck tube and the lug are of an integral symmetrical structure. The practical slip-on hubbed flange is simple in structure, reasonable in design, high in strength, strong in durability, good in use effect and provided with thread grooves to lead to firm fit.
Description
Technical field
The utility model relates to a kind of flange, is specifically related to a kind of practical downhand welding hubbed flange.
Background technique
Flange is again circular flange dish or bead.Flange be make pipe and pipe and and the interconnective part of valve, be connected in pipe end.Perforation on flange, bolt is close to two flanges.Between flange, with liner, seal.
The hubbed flange structure of using in prior art is mostly and is provided with corner angle, in use easily operator is caused to scuffing, and using process Security is relatively low, and the intensity of flange itself is general, as easy as rolling off a log damage, and serviceability is poor.And flange surface is smooth structure, during laminating, easily produce and slide, fixing not firm.
Model utility content
It is a kind of simple in structure, reasonable in design that the purpose of this utility model is to provide, and intensity own is high, and serviceability is strong, and using effect is good, and the thread groove of design can be so that the more firm practical downhand welding hubbed flange of laminating.
The technical solution of the utility model is, a kind of practical downhand welding hubbed flange, described practical downhand welding hubbed flange comprises flange plate, the projection of the neck tube on flange plate and flange plate bottom, described flange plate, neck tube and projection are provided with same endoporus, described neck tube arranges with described flange plate is vertical, described projection arranges with described flange plate is vertical, described neck tube and flange plate joint are provided with rounding, the external diameter size of described neck tube is less than the external diameter size of described projection, between described flange plate external diameter and described projection external diameter, be provided with fixing bolt mounting hole, described flange plate, neck tube and projection are integral type symplex structure.
In preferred embodiment of the utility model, described projection lower surface is provided with round thread groove.
In preferred embodiment of the utility model, the top of described neck tube is provided with round thread groove equally.
In preferred embodiment of the utility model, the diameter of described flange plate diameter, described endoporus and the diameter of described mounting hole diameter are than being 30:20:1.
In preferred embodiment of the utility model, described flange plate diameter is 300mm, and described diameter of bore size is 200mm, and described mounting hole diameter is 10mm.
In preferred embodiment of the utility model, the radius of described rounding is 8mm.
Described in the utility model is a kind of practical downhand welding hubbed flange, and the utility model is simple in structure, reasonable in design, and intensity own is high, and serviceability is strong, and using effect is good, and the thread groove of design can be so that laminating be more firm.
