Detailed Description
A flange quick joint structure comprises a flange body 1, wherein a quick joint 2 is arranged on one side of the flange body, and a plurality of bolt mounting holes 3 are formed in the flange body in the circumferential direction around an axis; the bolt mounting holes are elongated holes, the axes of the elongated holes point to the axis of the flange body, two or more fixing plates 4 are fixedly mounted on one side of the flange body, which is provided with the quick connector, the tail ends of the fixing plates extend out of the flange surface of the flange body, and locking bolts 5 are hinged to the fixing plates, locking heads 6 are screwed on the locking bolts, and locking plates 7 are sleeved in the middle of the locking bolts; four fixing plates 4 are evenly arranged on the flange body 1 along the circumferential direction, and locking bolts 5 with locking heads 6 and locking plates 7 are respectively arranged on the four fixing plates.
The flange body is provided with the elongated hole to replace the existing circular bolt mounting hole, and under the condition, even if a certain difference exists between the two flanges, the elongated hole can be partially overlapped with the circular bolt mounting hole of the other flange, so that the fastening requirement between the two flanges is met; simultaneously, fixed plate, locking bolt, locking head and the locking plate on the flange body have formed a locking structure jointly, and after propping up flange body and another flange, rotate locking bolt to the opposite side of another flange, then rotate the locking head and compress tightly the locking plate on another flange, can exert the clamping effort to flange body and another flange to improve joint strength.
Flange quick-operation joint design, the width that sets up bolt mounting hole 3 on flange body 1 is greater than the diameter size of same grade flange bolt mounting hole, more accurately says, bolt mounting hole, the width in its rectangular shape hole slightly is greater than the bolt mounting hole with the grade flange to make it possess certain cooperation regulating power, satisfy the hole site positional deviation that leads to because of the difference, thereby further improve flange quick-operation joint's commonality and application scope.
One side of flange body 1 dorsad quick-operation joint 2 is provided with annular convex seal platform 8, and the diameter of seal platform is greater than the size of the flange seal platform of same grade, slightly is greater than the setting of the flange seal platform of same grade through the size, can guarantee sealing performance under the condition that the flange has the cooperation deviation, and the use of cooperation fixed plate, locking bolt, locking head and locking plate can avoid the seal platform size difference and the sealed problem that probably produces simultaneously.
In the flange quick joint structure, the quick joint 2 comprises a connecting column 21 extending from the side surface of the flange body 1 and a connecting cylinder 22 provided with an annular groove, the connecting column and the connecting cylinder are detachably connected, and the connecting column and the connecting cylinder are provided with through holes communicated with each other along the axis; by means of the detachable structure, different types of connecting cylinders, such as the existing quick connector shown in figure 1 or the hose connector 23 for connecting hoses shown in figure 4, can be replaced conveniently to meet the use requirements of different devices.
