Preferably, the outer end of the change is circumferentially with anti-sliding burr.
Preferably, the left end of the right disk body is circumferentially with upper and lower two positioning columns to the left, and the right end of left disk body is opened Equipped with location hole corresponding with positioning column, the left side of the positioning column is arc-shaped, and positioning column is located at the outside of inserted block.
Preferably, the location hole is horn-like in being open to the right.
Preferably, it is an integral molding structure between the inserted block and right disk body.
The utility model proposes a kind of pipe flange, advantageous effect is:In use, the inserted block of the leftmost side is inserted into a left side In the through-hole of side, positioning column is then directed at location hole, is inserted into, such inserted block will be directed at corresponding stepped groove, two ladders There is gradient in the face that is connected between slot, and the extruding in this way, inserted block is turned left, sealing ring is just extruded tighter, increases sealing Property, change is rotated, is fixed, has thus accomplished multiple sealing ring sealings, though there are one damaged, it is also other, it improves Safety, sealing effect are more preferable.
Description of the drawings
Fig. 1 be the utility model proposes a kind of pipe flange structural schematic diagram;
Fig. 2 is the A schematic enlarged-scale views of Fig. 1;
Fig. 3 be the utility model proposes a kind of pipe flange front view.
In figure:1 left disk body, 2 right disk bodies, 3 connecting tubes, 4 stepped grooves, 5 holding tanks, 6 sealing rings, 7 inserted blocks, 8 changes, 9 gears Ring, 10 anti-sliding burrs, 11 positioning columns, 12 location holes.
Specific implementation mode
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.
Referring to Fig.1-3, the right side of a kind of pipe flange, including left disk body 1, left disk body 1 is equipped with corresponding right disk body 2, left Disk body 1 is plate-like with right disk body 2, and left disk body 1 and the middle part of right disk body 2 offer the perforative through-hole in left and right, two through-holes Opposite one end is respectively connected with connecting tube 3, and the right end of the through-hole in left side is circumferential to offer multiple rings at equal intervals along direction to the left The stepped groove 4 of shape, and the diameter of stepped groove 4 is gradually reduced from right to left, the joint face between two neighboring stepped groove 4 is in round platform The inclined surface of type, and the holding tank 5 of annular is offered on inclined surface, sealing ring 6, the left end of right disk body 2 are installed in holding tank 5 Inserted block 7 equipped with multiple annulars corresponding with stepped groove 4, is an integral molding structure between inserted block 7 and right disk body 2, convenient for manufacturing, Here inserted block 7 mills out to come there are one monoblock, and the diameter of inserted block 7 from left to right gradually increases.
