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 utility model has the beneficial effects that the utility model is reasonable in design, pipe is led to
Connector installation is crossed, pipe installation effectiveness is can be improved, filter screen is mounted in strainer mounting groove, it can be to the liquid in pipe
It is filtered, and sealing rubber ring is placed in seal groove, then connect two groups of ring flanges by connection bolt and mounting hole
It connects, can use the fitting between two groups of ring flanges can promote sealing rubber ring to be nested in realization sealing in seal groove, guarantee sealing
Cushion rubber will not directly be 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 the utility model overall structure diagram；
Fig. 2 is the utility model structure 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
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of slip-on welding flange, including ring flange 1, flange
The top of disk 1 is fixedly installed neck platform 2, and the top of neck platform 2 is provided with connector 3, offers longitudinal direction at the lumen centers of ring flange 1
Perforative flange hole 4, and 4 top of flange hole sequentially passes through neck platform 2 and connector 3 upwards, the bottom of ring flange 1 offers and flange
The seal groove 5 that hole 4 is connected offers strainer mounting groove 7, the top of ring flange 1 on the side side wall far from opening in seal groove 5
Portion 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 straight of flange hole 4
Diameter, sealing rubber ring can be installed in seal groove 5 by this set can increase the sealing effect of flange, while pacify in strainer
The filter screen installed in tankage 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 be installed in mounting groove 5 by this set close
