Summary of the invention
The purpose of the present invention is to provide a kind of slip-on welding flanges, to solve the problems mentioned in the above background technology.
To achieve the above object, the invention provides the following technical scheme: a kind of slip-on welding flange, including ring flange, the method It is fixedly installed neck platform at the top of blue disk, connector is provided at the top of the neck platform, is opened up at the lumen centers of the ring flange There is longitudinal perforative flange hole, and the flange hole top sequentially passes through neck platform and connector upwards, the bottom of the ring flange is opened Equipped with the seal groove being connected with flange hole, strainer mounting groove is offered on the side side wall far from opening in the seal groove, The top circumference side of the ring flange is uniformly provided with mounting hole, offers arc transiting surface on the side wall of the neck platform.
Further, the mounting hole is uniformly arranged along the circumferencial direction at the top of ring flange and opens for six groups of structures are identical Mouth through-hole, and chamfering is provided at the top and bottom of open hole.
Further, the diameter of the seal groove is greater than the diameter of strainer mounting groove, and the diameter of the strainer mounting groove Greater than the diameter of flange hole.
Further, the depth of the seal groove is greater than the depth of strainer mounting groove.
Further, the ring flange and neck platform are body of stainless steel, and the ring flange and neck platform pass through welded connecting.
Further, the radian of the arc transiting surface is tilted to flange hole direction of axis line.
Compared with prior art, the beneficial effects of the present invention are: inventive structure design rationally, by pipe is pacified by connector Dress, can be improved pipe installation effectiveness, filter screen is mounted in strainer mounting groove, can carry out to the liquid in pipe Filter, and sealing rubber ring is placed in seal groove, then connects two groups of ring flanges with mounting hole by connection bolt, can be with Sealing rubber ring can be promoted to be nested in seal groove using the fitting between two groups of ring flanges and realize sealing, guarantee that sealing rubber ring will not It is directly contacted with air, can reduce the degree of aging of sealing rubber ring, ensure that the leakproofness of ring flange installation.
Detailed description of the invention
Fig. 1 is overall structure of the present invention;
Fig. 2 is structure of the invention bottom view.
In figure: 1 ring flange, 2 neck platforms, 3 connectors, 4 flange holes, 5 seal grooves, 6 mounting holes, 7 strainer mounting grooves, 8 arc mistakes Cross face.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of technical solution referring to FIG. 1-2: a kind of slip-on welding flange, including ring flange 1, ring flange 1 Top is fixedly installed neck platform 2, and the top of neck platform 2 is provided with connector 3, and longitudinal run through is offered at the lumen centers of ring flange 1 Flange hole 4, and 4 top of flange hole sequentially passes through neck platform 2 and connector 3 upwards, and the bottom of ring flange 1 offers and flange hole 4 The seal groove 5 being connected offers strainer mounting groove 7, the top of ring flange 1 on the side side wall far from opening in seal groove 5 Circumference side is uniformly provided with mounting hole 6, and arc transiting surface 8 is offered on the side wall of neck platform 2.
Mounting hole 6 is uniformly arranged along the circumferencial direction at the top of ring flange 1 as the identical open hole of six groups of structures, and is opened It is provided with chamfering at the top and bottom of mouth through-hole, convenience when connection bolt installation can be increased by this set, together When can increase stable connection degree between two groups of ring flanges 1 by six groups of mounting holes 6;
The diameter of seal groove 5 is greater than the diameter of strainer mounting groove 7, and the diameter of strainer mounting groove 7 is greater than the diameter of flange hole 4, Sealing rubber ring can be installed in seal groove 5 by this set can increase the sealing effect of flange, while install in strainer The filter screen installed in slot 7 can be filtered the liquid in pipe;
The depth of seal groove 5 is greater than the depth of strainer mounting groove 7, can install sealant in mounting groove 5 by this set The filter screen of strainer mounting groove 7 can be limited when circle, leakproofness when can be improved between two groups of flanges;
Ring flange 1 and neck platform 2 are body of stainless steel, and ring flange 1 and neck platform 2 be by being welded to connect, can be with by this set Improve the stable connection degree between neck platform 2 and ring flange 1;
