It is gradually reduced, the joint face between two neighboring stepped groove is in the inclined surface of circular platform type, and the appearance of annular is offered on inclined surface
It receives slot, sealing ring is installed in the holding tank, the left end of the right disk body is equipped with the slotting of multiple annulars corresponding with stepped groove
Block, and the diameter of inserted block from left to right gradually increases, the connection shape between two neighboring inserted block is corresponding with inclined surface, and inserted block
There are top clearances between corresponding stepped groove, and the circumferential direction of the right disk body is socketed with change, and the right end of change is equipped with gear
Ring, the baffle ring are against on the right side of right disk body, are threadedly coupled between the change and left disk body.
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
