Abstract
The utility model relates to a pipeline connecting device which comprises a connecting pipeline, wherein the end heads of the connecting pipeline are provided with outer threads and fastening screw caps matched with the outer threads. The inner diameter of each end head of the connecting pipeline is a bit larger than the outer diameter of a pipeline to be connected. The utility model also comprises an inner liner, a sealing washer and an outer fastening ring of the pipeline needing connection. The utility model has the advantages of material saving and easy processing and installation. A pipeline connected by the utility model has the advantages of less loss of pipeline pressure and high water overflow, and the leakage is difficult to happen.
Description
The utility model relates to a kind of assembling pipe joint.
Present non-full-metallic pipeline such as plastic-aluminum pipe, copper are moulded the assembling pipe joint that pipe, steel are moulded pipe etc., the termination of its connecting tube is provided with a connecting head that is connected as a single entity, this connecting head inserts to be needed in the connecting tube, reason owing to processing, this connecting head wall thickness is bigger, thereby greatly increased pipe resistance, and causing the huge pressure loss, the pipeline water amount obviously reduces to take place easily seepage.
The purpose of this utility model is to provide a kind of assembling pipe joint that overcomes above defective.
For achieving the above object, the utility model is by the following technical solutions: it comprises connecting tube, the termination of connecting tube is provided with outside thread, it also is provided with the fastening nut that cooperates with this outside thread, the internal diameter of connecting tube termination needs the outer diameter tube of connection bigger, it also is provided with the neck bush and the seal washer of the pipeline that needs connection, and the outer fastening ring that needs the pipeline of connection.
The utility model also can adopt following further technological scheme simultaneously:
The top of described neck bush is provided with limited ring.
Described outer fastening ring seals.
Owing to adopt technique scheme, the utility model adopts neck bush to insert and needs connecting tube, because neck bush is processed separately, its wall thickness is thinner, thereby the pipeline that is connected by the utility model, and duct pressure loss is less, and water amount is difficult for taking place seepage greatly.Outer fastening ring also can play the second road leakage barrier for sealing.It is simple to adopt structure material of the present utility model to economize installation and processing.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a sectional view of the present utility model.
With reference to accompanying drawing.The utility model comprises connecting tube 1, the termination 2 of connecting tube is provided with outside thread 3, it also is provided with the fastening nut 4 that cooperates with this outside thread, the internal diameter of connecting tube termination needs pipeline 9 external diameters of connection bigger, it also is provided with the neck bush 5 and the seal washer 6 of the pipeline that needs connection, and the outer fastening ring 7 that needs the pipeline of connection.
The top of described neck bush can be provided with limited ring 8.
Described outer fastening ring can seal.
During use, tighten nut at need connecting tube overcoat, put outer fastening ring again, neck bush is inserted needs connecting tube again, puts into packing ring in the termination, need insert the termination by connecting tube then, screws with fastening nut to get final product.
