Abstract
The invention discloses a non-national standard welding neck flange with a groove in an outer neck wall. The non-national standard welding neck flange comprises a welding neck flange body, the welding neck flange body is provided with a flange bottom plate and a flange neck, the flange neck is provided with the rectangular groove, an arc chamfered corner is arranged on an opening of the rectangular groove, and the distance from the rectangular groove to the end of the flange neck is at least one centimeter, wherein the thickness of the flange bottom plate is 1/3-1/4 of the height h of the welding neck flange body, and the height h of the welding neck flange body is smaller than the outer diameter L of the flange neck. According to the invention, the problems that locating is easily inaccurate and the connection difficulty is high in the actual connection process of welding neck flanges are solved, the flanges and connection pipelines can be sealed better, the structure is simple, and mass production is easy.
Description
Technical field
The present invention relates to a kind of non-GB adpting flange, more particularly, relate to the non-GB hubbed flange that groove established by a kind of outer neck wall.
Background technique
Flange is the blue flange disk of call again.Flange is interconnective part between pipe and pipe, for the connection between pipe end; Also the flange that the equipment that is used in is imported and exported is had, for the connection between two equipment, as speed reducer flange.Perforation on flange, bolt makes two flanges be close to.Liner containment is used between flange.Flange is all generally use in pairs, and low pressure pipeline can use an acting flange, and four kilograms with the use welded flange of upward pressure.Add sealing gasket between two panels flange plate, then use bolton.Every union piece using bolt connection simultaneously to close at two planar perimeter, is generally all called " flange ".Present most hubbed flange is all smooth neck, so easily locates when being arranged on actual connection inaccurate, and the difficulty of connection strengthens.I arranges groove at the neck of hubbed flange at corporation plan, strengthens the connection frictional force between hubbed flange and connecting tube.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, claimant, through repeatedly putting into practice improvement, devises the non-GB hubbed flange that groove established by outer neck wall, easily locates inaccurate time main purpose is and solves hubbed flange actual connection, the problem that the difficulty connected is larger, reaches sealing effect better.
Technological scheme: in order to realize foregoing invention object, the technical solution adopted in the present invention is: the non-GB hubbed flange of groove established by outer neck wall, comprise hubbed flange body, described hubbed flange body is provided with flange chassis and neck flange, described neck flange is provided with rectangle groove, described rectangle groove notch arranges circular arc chamfering, and the distance between described rectangle groove and the termination of neck flange is at least 1cm.
Further, the further technological scheme that the present invention adopts is: the thickness on described flange chassis is 1/1 to four/3rd of hubbed flange body height h.
Described hubbed flange body height h is less than the external diameter L of neck flange.
Described flange chassis arranges some flange connecting holes.
Again further, the material of the body of adpting flange described in the present invention can be any one in carbon steel, stainless steel or alloyed steel.
Beneficial effect: compared with prior art, its beneficial effect is in the present invention:
Easily locate inaccurate when 1, the invention solves the actual connection of hubbed flange, the problem that the difficulty of connection is larger, to reach between flange and connecting tube sealing effect better.
2, of the present invention relatively simple for structure, easily produce in batches.
Accompanying drawing explanation
Fig. 1 is the structural representation that the non-GB hubbed flange of groove established by the outer neck wall of the present invention.
Embodiment
Below by a most preferred embodiment, the technical program is described in detail, but protection scope of the present invention is not limited to described embodiment.
As shown in Figure 1, the non-GB hubbed flange of groove established by outer neck wall, comprise hubbed flange body 1, described hubbed flange body 1 is provided with flange chassis 4 and neck flange 5, described neck flange 5 is provided with rectangle groove 2, described rectangle groove 2 notch arranges circular arc chamfering, and the distance between described rectangle groove 2 and the termination of neck flange 5 is at least 1cm.
The thickness on described flange chassis 4 is 1/1 to four/3rd of hubbed flange body 1 height h.
Described hubbed flange body 1 height h is less than the external diameter L of neck flange 5.
Described flange chassis 4 arranges some flange connecting holes 3.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
