Abstract
The utility model provides a riveting structure of a riveting metal (or external metal layer) pipeline. The utility model has a cylindrical sealing part arranged in the pipe part. Enough external force of the sealing part is uniformly acted on the periphery of the pipe part, the pipe part and the pipe material are locally relieved; after the pipe part and the pipe material reach the riveting with enough strength, the effective sealing is synchronously reached. The utility model has extremely simple structure and installation, is especially suitable for application of the fuel and water supply system.
Description
The utility model relates to low-cost connection of pipeline in the pipeline transporting system.
The pipeline transporting system is by the some pipes composition that is connected.Connection tradition Coating Steel Pipe between the tube and tube is directly to connect with bolt, its sealing is the filler with linen thread or white glues band and so on, if on various novel tubes, make screw thread, the one, owing to the reason of material causes the screw strength deficiency, the 2nd, under the enough situation of the strength of materials, its tubing thickness must increase, its manufacture cost is higher naturally like this, and do not have the silk bayonet joint on the tubing in most novel tubes is by the attached nut of pipe fitting, seal ring, the part that pipe fitting or the like is numerous is realized connecting and sealing, its pipe fitting cost is just high, and this just has certain distance with common people's ability to accept.
The purpose of this utility model is to overcome higher this shortcoming of pipe fitting manufacture cost in the existing material pipe-line system, provide a kind of tubing, pipe fitting cost are reduced greatly and its connection, the sealing reliable and effective again riveted type pipeline connecting parts.
The technical solution that realizes the utility model purpose is such: the riveted type pipeline connecting parts that is provided is a kind of low cost new pipe fitting, this pipe fitting body one end inwall is one cylindrical, inwall is provided with the riveted joint convex edge, and the cylindrical seal that is complementary with pipe fitting places in this cylindrical body.Pipe fitting described in the utility model is to be close to connecting and composing between the tubing by the riveted joint convex edge and the Sealing that can be set on the pipe fitting in the tubing connecting end groove with being connected of tubing.The section configuration that installs convex edge on the rear tubular member and tubing upper groove can be rectangle, rhombus, various geometrical shapies such as trapezoidal.During installation tubing is inserted back, pipe fitting bottom and apply uniform external pressure simultaneously on pipe fitting external diameter circumference, make its pipe fitting press to tubing, force pipe fitting, the local tube reducing of tubing, riveting by force under external force at last is one.Groove can be together, two roads or N road, Sealing between pipe fitting and tubing also is under pressure this moment simultaneously, make it to be filled with the gap between tubing and the pipe fitting, thereby play effective seal, when pipe fitting and tubing can not relatively move, again the inside and outside of pipe fitting and tubing isolated fully like this.
Described connection sealing means is to utilize external force pressure pipe fitting, tubing, make pipe fitting, tubing produce corresponding recesses and rivet, its sealing is to utilize the Sealing on the pipe fitting to seal, this structure only needs to apply equably external force on the pipe fitting cylindrical can realize connecting sealing, obviously pipe fitting, tubing also can be instead for establishing it.
Described connection sealing means also is suitable for flexible pipe, only needs to load onto a bit of rigid pipe at the flexible pipe front end, and having made it enough rigidity can use.
The utility model has the advantages that the manufacture cost of pipe-line system is descended greatly, it is good, simple in structure, easy for installation that it connects reliable sealing, and the connection that is particularly suitable for the metal tube in water supply system, this class black pipe of gas burning system is used.
The utility model is described in further detail below by accompanying drawing, embodiment.
Fig. 1 is the utility model organigram.
Fig. 2 is the riveted joint schematic representation in the installation process.
Fig. 3 is a scheme of installation.
Fig. 4 is embodiment one figure.
As shown in the figure, this practicality newly comprises pipe fitting body 1 and tubular shape Sealing 2, it is characterized in that: this pipe fitting body one end inwall is a cylinder type, and the cylinder type Sealing 2 that is complementary with it places in this cylindrical body and constitutes socket fitting type structure.The other end of pipe fitting body can be socket fitting type structure, also can be the inner and outer pipe screw thread, and this pipe fitting body can be straight tube, 45 ° or 90 ° of bend pipes, threeway branch pipe and relevant reducer pipes.
As shown in Figure 2: during the utility model connection, pipe 3 inserts and presets Sealing 2 in the pipe fitting bodies 1.
As shown in Figure 3: pipe fitting 1 and pipe 3 are riveted together securely with special tool 4.
Claims (2)
1, riveted type pipeline connecting parts is characterized in that this pipe fitting body one end inwall is one cylindrical, and inwall is provided with the riveted joint convex edge, and the cylindrical seal that is complementary with pipe fitting places in this cylindrical body.
2, riveted type pipeline connecting parts as claimed in claim 1, it is characterized in that: the other end of pipe fitting body can be socket fitting type structure, also can be the inner and outer pipe screw thread, and this pipe fitting body can be straight tube, 45 ° or 90 ° of bend pipes, threeway branch pipe and relevant reducer pipes.
