Abstract
The utility model has disclosed a kind of welding neck flange, comprise flange plate and inertance tube, described flange plate and described inertance tube are structure as a whole, in the middle of described flange plate and inertance tube, it is through-hole structure, and inwall is smooth arc surface, described flange plate and inertance tube are provided with chamfering in joint, and described chamfering is arc round angle, and the thickness size of described flange plate is 1:25 with the height size of described inertance tube ratio.The utility model can increase the length of construction, is convenient to the connection of specific use, and intensity own is high, and serviceability is strong, and using effect is good.
Description
Technical field
The utility model relates to a kind of flange, is specifically related to a kind of welding neck flange.
Background technique
Flange is again flange plate 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, seal with liner.
At some in particular cases, between two links because distance is at a distance of slightly far away, need to fill up by middle flange connector, but existing flange connector is mostly highly shorter, and in urgent need situation, conventionally all adopt some plastics or tinsel to be fitted on the neck tube of flange connector and carry out need to fill up time, but the intensity that these class methods connect in the middle of causing is low, as easy as rolling off a log damage, serviceability is poor.
Model utility content
The purpose of this utility model is to provide a kind of length that increases construction, is convenient to the connection of specific use, and intensity own is high, and serviceability is strong, the welding neck flange that using effect is good.
The technical solution of the utility model is, a kind of welding neck flange, described welding neck flange comprises flange plate and inertance tube, described flange plate and described inertance tube are structure as a whole, in the middle of described flange plate and inertance tube, be through-hole structure, and inwall is smooth arc surface, described flange plate and inertance tube are provided with chamfering in joint, described chamfering is arc round angle, and the thickness size of described flange plate is 1:25 with the height size of described inertance tube ratio.
In preferred embodiment of the utility model, the thickness of described flange plate is 2cm.
In preferred embodiment of the utility model, the height of described inertance tube is 50cm.
In preferred embodiment of the utility model, the diameter of described flange plate is 10cm.
In preferred embodiment of the utility model, the external diameter of described inertance tube is 6cm.
In preferred embodiment of the utility model, the through-hole diameter of described flange plate and inertance tube is 3cm.
In preferred embodiment of the utility model, the radius of described arc round angle is 1cm.
Described in the utility model is a kind of welding neck flange, and the utility model can increase the length of construction, is convenient to the connection of specific use, and intensity own is high, and serviceability is strong, and using effect is good.
Brief description of the drawings
Fig. 1 is the sectional view of welding neck flange in the utility model one preferred embodiment;
In accompanying drawing, each mark is as follows: 1, flange plate, 2, inertance tube, 3, chamfering.
Embodiment
Below preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Described in the utility model is a kind of welding neck flange, shown in Figure 1, described welding neck flange comprises flange plate 1 and inertance tube 2, described flange plate 1 and described inertance tube 2 are structure as a whole, in the middle of described flange plate 1 and inertance tube 2, be through-hole structure, and inwall is smooth arc surface, described flange plate 1 and inertance tube 2 are provided with chamfering 3 in joint, described chamfering 3 is arc round angle, and the thickness size of described flange plate 1 is 1:25 with the height size of described inertance tube 2 ratio.
Further, the thickness of described flange plate 1 is 2cm.
Further, the height of described inertance tube 2 is 50cm.
Further, the diameter of described flange plate 1 is 10cm.
Further, the external diameter of described inertance tube 2 is 6cm.
Further, the through-hole diameter of described flange plate 1 and inertance tube 2 is 3cm.
Further, the radius of described arc round angle is 1cm.
The flange surface that the utility model is produced does not have the defect of crackle, burr, scuffing and other reduction intensity and connection reliability.
And each side production error is 1mm.
Described in the utility model is a kind of welding neck flange, and the utility model can increase the length of construction, is convenient to the connection of specific use, and intensity own is high, and serviceability is strong, and using effect is good.
The foregoing is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
