The purpose of this utility model is achieved through the following technical solutions:
A kind of band divides the lap joint flange of half snap ring, wherein:
Described lap joint flange be installed on end outer surface have first of circular groove take over and port with the second jointing of taking over of flange plate, wherein the first end face of taking over is with circle shape groove, described lap joint flange comprises:
Two minutes half snap rings, symmetrically, the inwall of each snap ring is a stepped shaft, and its Lower Half wall thickness forms an annulus greater than first half wall thickness after half snap ring docking in two minutes, and the thick part of this annulus mesospore is stuck in the first circular groove of taking over;
The lap joint flange dish, be placed on the annulus of described two minutes half snap ring compositions, with the annulus contacting point be fixing structure, its docking bolt hole structure is corresponding with the docking bolt hole structure of the described second flange plate of taking over, adopt bolt, nut with the lap joint flange dish be connected the flange plate of taking over and connect, be provided with a rotation auxiliary bolt hole on the cylindrical of lap joint flange dish side.
Described the first adapter is water pump inlet/outlet pipe.
Described the second adapter is the test bed entrance sleeve of water pump.
Mounting O-shaped seal ring in the described first end face circle shape groove of taking over.
Described lap joint flange dish one end face is provided with two dismounting auxiliary bolt holes.
The beneficial effects of the utility model:
band of the present utility model divide the lap joint flange of half snap ring be installed on end outer surface have first of circular groove take over and port with the second jointing of taking over of flange plate, two minutes half snap rings in the lap joint flange of band minute half snap ring form an annulus and are placed in the first adapter circular groove, the inwall of snap ring is a stepped shaft, be nested with a lap joint flange dish corresponding with the second flange plate structure of taking on the annulus of this minute half snap ring composition, make two after the flange plate that this lap joint flange dish and second is taken over is connected and take over connections, this is simple in structure, easy accessibility, and can rotate after connecting and adjust the pipeline angle, greatly improve the efficient of taking over connection work, this lap joint flange is applicable to first of different size and takes over use.
For further illustrating above-mentioned purpose of the present utility model, structural feature and effect, below with reference to accompanying drawing, the utility model is elaborated.
Description of drawings
Fig. 1 is that band of the present utility model divides the lap joint flange of half snap ring and the schematic diagram after the pipeline assembling;
Fig. 2 is lap joint flange and the pipeline assembling unfolded drawing in Fig. 1;
Fig. 3 is the flange plate structure figure in Fig. 2;
Fig. 4 is minute half Snap ring structure figure in Fig. 2.
Embodiment
Accompanying drawing below in conjunction with embodiment is elaborated to embodiment of the present utility model.
Referring to Fig. 1-Fig. 2, band of the present utility model divides the lap joint flange of half snap ring to be installed on end outer surface has the first adapter 1 of circular groove 11 and port to take over 2 jointing with second of flange plate 21, wherein the end face of the first adapter 1 is with circle shape groove 12, and described band divides the lap joint flange of half snap ring to comprise:
Two minutes half snap rings 7, symmetrically, the inwall of each snap ring is a stepped shaft, as shown in Figure 4, its Lower Half wall thickness is greater than first half wall thickness, and cross section is L-type, forms an annulus after half snap ring docking in two minutes, the thick part of this annulus mesospore is stuck in the circular groove 11 of the first adapter 1, and in the present embodiment, the first adapter 1 is water pump inlet/outlet pipe.
Lap joint flange dish 6, the docking bolt hole structure of the flange plate 21 of its docking bolt hole structure and the second adapter 2 is corresponding, it is placed on the annulus of described two minutes half snap ring 7 compositions, with the annulus contacting point be fixing structure, form a complete flange Connecting format, then with bolt 4, nut 3, the flange plate 21 of lap joint flange dish 6 and the second adapter 2 is tightened, just the pipeline of two adapters can be coupled together, in the present embodiment, the second adapter 2 is the test bed entrance sleeve of water pump.
In order to make two adapters be connected with good sealability, take over 1 the interior mounting O-shaped seal ring 5 of end face circle shape groove 12 first, can play sealing effect preferably.
