A barrier is arranged on the prismaid along the direction of a nozzle of the through pipe; a groove is formed between the external side of the through pipe and the barrier. The utility model has the advantages of simple structure, easy installation and low cost.
Description
The utility model relates to a kind of pipe fitting joint, particularly the special joint of plastic-aluminum pipe fitting.
The used pipe fitting regulation of construction and installation at present must be used plastic-aluminum spare, because can not directly carrying out screw thread at pipe end when connecting, handles by such pipe fitting, so if guarantee good sealing effect, just need special processing, the joint of existing plastic-aluminum pipe is just done complicatedly and is heavy, and such joint all adopts particularly copper sleeve of metal, and cost is very high.
The purpose of this utility model is a kind of plastic-aluminum pipe special joint of design, the characteristics that this joint has is simple in structure, install easily, cost is low.
The utility model is achieved in that a kind of tubing special joint, and it comprises that an outside is provided with the siphunculus of terrace with edge, and the siphunculus opening direction is provided with plate washer in described terrace with edge upper edge, and the siphunculus outside forms a groove with plate washer.
Above-mentioned plate washer is provided with along siphunculus excircle direction.
Above-mentioned siphunculus and plate washer are metal constructions.
Above-mentioned siphunculus and plate washer are copper spares.
The utility model promptly constitutes aluminium plastic pipe joint owing to only have the siphunculus and the plate washer on it of terrace with edge, so structure is very simple, and use less metal or copper spare than at present used aluminium plastic pipe joint, so cost reduces greatly, during connection, the plastic-aluminum pipe that needs are connected inserts groove, tightens up sealing with the hydraulic pressure installation pressurization and gets final product, so install easily.
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is the straight joint sectional view that is connected with the plastic-aluminum pipe;
Fig. 2 is the angle coupling sectional view that is connected with the plastic-aluminum pipe;
Fig. 3 is the tee union sectional view that is connected with the plastic-aluminum pipe;
Fig. 1 is embodiment 1 of the present utility model, siphunculus 1 is the equal coupling pipe, terrace with edge 2 is structure as a whole with siphunculus 1 on it, at this terrace with edge 2 is an annular boss, annular plate washer 3 is located on the boss, form two annular grooves 4, the plastic-aluminum pipe 5 of two need connections promptly inserts in two grooves 4, plate washer 3, the siphunculus 1 that will be generally copper spare by dedicated hydraulic equipment compress sealing with plastic-aluminum pipe 5, the nothing leakage that has promptly realized the plastic-aluminum pipe connects, annular plate washer 3 can be structure as a whole with boss, also can be absolute construction; In groove 4, also be provided with rubber O type circle.
Fig. 2 is embodiment 2 of the present utility model, and siphunculus 1 is an elbow bend, is respectively equipped with two 2, two annular plate washers 3 of annular terrace with edge that are structure as a whole with elbow bend at the turning of elbow bend and is located at respectively on two annular terrace with edges 2.
Fig. 3 is embodiment 3 of the present utility model, and siphunculus 1 is a three-way pipe, and annular terrace with edge 2 and annular plate washer 3 are three.
The utility model is not limited only to the connection of plastic-aluminum tubing.
