Abstract
The utility model belongs to the technical field of machinery, relates to a flange, in particular to a fastening flange, and resolves the problems that a flange of the prior art is complex in installation and disassembling and the like. The fastening flange comprises a disk-shaped main body, and the center of the main body is provided with a first through hole. The fastening flange is characterized in that the main body is provided with a small-diameter cylindrical protruding body which is provided with a second through hole, and the external edge of the protruding body is provided with a plurality of fasteners for fastening. The fastening flange has the advantages of being convenient in installation and disassembling and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of flange, especially relates to a kind of snapping flange.
Background technique
Flange is flange plate or bead again.Flange is to make pipe and the interconnective part of pipe, is connected in pipe end.Under many circumstances, adopt so-called flange or the free flange taken to substitute adpting flange in the pipe end permanent weld, the leakproof overlap joint of setting up two pipe ends connects, and perhaps flanged the or flared coupling of pipeline and stream socket or overlap with leakproof as valve, pump and so on other flanged parts is connected.
This class flange free or unsteady flange is specially adapted to transmit the pipeline and the low pressure pipeline of flue gas, gaseous mixture, forced ventilation air, liquid, suspension and other fluid, often adopts making than light-weight pipe of steel plate, Corrugated Steel, plastics, fiber-reinforced resin, vulcanized rubber and so on.In the pipeline situation that the overlap joint or the application of free flange are specially adapted to make than expensive material as stainless steel, titanium and so on, need be to the fluid corrosion protection of the pipe of flowing through.This is owing to can make the lap flange that does not directly contact with fluid with not too expensive material.
Owing to do not have the hole on the welding ring of pipeline or pipe or the end flange, radial width is less, and is not enough to guarantee that in the self-stiffness that they have under many situations flange is to being inserted in the hydraulic seal of packing ring between tube end flange and other pipe or the pipe joint end flange.In these were used, lap flange also must be considered the deficiency of tube end enlarging robustness except the bolt that is provided for being fastenedly connected or pull bar fixing.
In addition, now the flange of usefulness connects by through hole normally by through hole is set up, or is set to tapped hole and connects.Such technological scheme is relatively loaded down with trivial details when connecting, and also must expend the regular hour during dismounting.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of compact structure is provided, the flange of being convenient to mount and dismount.
For achieving the above object, the utility model has adopted following technical proposal: a kind of snapping flange comprises a disc body, this main center is provided with through hole one, it is characterized in that described main body is provided with the prominent body of the less cylindrical body of diameter, this prominent body also has through hole two; Prominent external edge is provided with the button that several are used for snapping.
In above-mentioned a kind of snapping flange, described through hole one is identical with through hole two diameters.
In above-mentioned a kind of snapping flange, described button has 4.
In above-mentioned a kind of snapping flange, be provided with the groove of being convenient to screens between described prominent body and the main body.
Compared with prior art, the advantage of this snapping flange is:
1, because prominent external edge is provided with the button that several are used for snapping, therefore can be connected with corresponding pipeline efficiently, and circumferentially locate by button.
2, the groove that is provided with between prominent body and the main body, when being convenient to connect, flange is connected with pipeline axial.
Description of drawings
Fig. 1 is that structure master of the present utility model looks schematic representation;
Fig. 2 is that structural upright of the present utility model is looked schematic representation.
Among the figure, 1, main body; 2, through hole one; 3, prominent body; 4, through hole two; 5, button.
Embodiment
As shown in Figure 1, 2, a kind of snapping flange comprises a disc body 1, and this main body 1 center is provided with through hole 1, and described main body 1 is provided with the prominent body 3 of the less cylindrical body of diameter, and this prominent body 3 also has through hole 24; Described through hole 1 is identical with through hole 24 diameters; Be provided with the groove of being convenient to screens between prominent body 3 and the main body 1.When being convenient to connect, flange is connected with pipeline axial.
