Abstract
The utility model relates to a pipeline connecting piece for a pipelining system, which comprises a pipe body with a cylindrical internal wall on an end, a cylindrical sealing member and a riveted ring are matched inside and outside the pipe body. During the assembling, tubing is inserted in a sealing end of the pipe body, and then the external pressure is applied on an external diameter circle of the riveted ring, to force the pipe body and the tubing for tube reducing partially, so that the pipe body and the tubing can be connected and sealed as a whole. The utility model has the advantages of simple structure, low cost, reliable connection, good salability and convenient assembly and is applicable to the connection of the metal tube in a black pipe of a water supply system and a fuel gas system.
Description
Affiliated technical field
The utility model belongs to the pipe connecting device technical field, relates to a kind of low-cost pipeline connecting parts that is used for the pipeline transporting system.
Background technique
In the existing material pipeline transporting system, the connection of traditional approach all is directly to link to each other with bolt between the Coating Steel Pipe, and sealed with the filler of linen thread or white glues band and so on, the problem of its existence is: if make screw thread on various novel tubes, the one, owing to the reason of material may cause the screw strength deficiency, the 2nd, under the enough situation of the strength of materials, its tubing thickness must increase, and so just will increase manufacture cost.And the no silk bayonet joint structure that adopts in some novel tubes at present is to realize connecting and sealing by numerous attached replacing the spare parts such as the attached nut of pipe fitting, seal ring, pipe fitting, its pipe fitting cost is high especially, with the ability to accept of general public certain distance is arranged obviously.
The model utility content
The purpose of this utility model is to overcome the problem that prior art exists, provide a kind of tubing and pipe fitting cost are reduced greatly and connect, seal not only reliably but also effectively riveted the ring type pipeline connecting parts.
Be used to realize that the technical solution of foregoing invention purpose is such: the riveted joint ring type pipeline connecting parts that is provided is a kind of low cost new pipe fitting, it has one one end inwall is columnar pipe fitting body, coupling is lined with cylindrical seal on this end pipe fitting inner body wall, be arranged with one to multiple road riveted joint ring in this external coupling of this end pipe fitting, the other end of pipe fitting body is spigot and socket type or inner and outer pipes worm structure.During installation tubing inserted behind the pipe fitting body sealed end riveted joint ring (or will rivet the outside that boxing is connected on the pipe fitting body in advance) on the link outer cover, on riveted joint ring external diameter circumference, apply uniform external pressure simultaneously, and press to tubing by pipe fitting body and riveted joint ring, force the local tube reducing of pipe fitting body and tubing, at last under external force the two by riveted joint by force for one, meanwhile the pipe fitting Sealing also is subjected to powerful pressure, make it to be full of the gap between pipe fitting and the tubing, thereby play the effective seal effect.
Compared with prior art, pipeline connecting parts described in the utility model simple in structure, connect reliable, good airproof performance, easy for installation, practicing of its product can make the manufacture cost of pipe-line system descend greatly, and the connection that is particularly suitable for the metal tube in water supply system, the gas burning system black pipe is used.
Description of drawings
Fig. 1 is the schematic representation of a kind of specific embodiment structure of the utility model.
Fig. 2 is a view before structure embodiment illustrated in fig. 1 and the tubing field riveting.
Fig. 3 is the scheme of installation of structure embodiment illustrated in fig. 1 and tubing.
Fig. 4 and Fig. 5 are respectively the utility model schematic representation of two kinds of specific embodiment structures in addition.
Embodiment
Referring to accompanying drawing, riveted joint ring type pipeline connecting parts described in the utility model comprises pipe fitting body 1, cylindrical seal 2 and circular riveted joint ring 3 three parts, its basic structure is as shown in Figure 1: an end inwall of this pipe fitting body is cylindrical, and cylinder type Sealing 2 that is complementary with it and riveted joint ring 3 place this cylindrical body inwall and outside and constitute socket fitting type structure respectively.During installation, with the Sealing that presets in the tubing 5 insertion pipe fitting bodies 1, utilize the riveted joint circulating application of 6 pairs of pipe fitting body exterior of special tool to add enough external force, make pipe fitting, riveted joint ring, tubing produce corresponding grooves, in that make again can be inside and outside fully every close with tubing with pipe fitting body 1, riveted joint ring 3 when can not relatively move between pipe fitting body 1 and the tubing 5, realized being connected and sealing (referring to Fig. 2 and Fig. 3) of pipe fitting body 1 and tubing 5 like this.Figure 4 shows that another kind of example structure of the present utility model, be provided with at the pipe fitting body 1 of this structure on the tube wall of cylindrical seal 2 and be provided with one to multiple road annular recess 4, riveted joint ring 3 couplings are set in each groove 4, and this structure only needs to apply enough power equably on riveted joint ring cylindrical on the pipe fitting and can realize being tightly connected.In the product actual fabrication, pipe fitting body 1 can be straight tube, 45 ° or 90 ° of bend pipes, threeway branch pipe or relevant reducer pipes, also can be made into two mutual-inserting type structure as shown in Figure 5.
The connection sealing means that adopts according to structure described in the utility model is suitable for too to flexible pipe, only need be used in the flexible pipe front end during use and load onto a bit of rigid pipe, makes it to have enough rigidity and promptly can be used for installing.
Claims (3)
