Abstract
The utility model relates to a pipeline connection structure which comprises a joint body 1, and a stainless steel pipe 4. The improvement of the utility model is that a convex hub 5 is arranged at the end part of the stainless steel pipe 4. A sealing ring 2 is fixed and pressed tightly by the joint body 1, the stainless steel pipeline 4 and a plug screw 3, wherein, the joint body 1 is connected with the plug screw 3 by screw threads. Due to that the pipeline connection structure abandons the traditional screw thread sealing mode, the end of the pipe is not provided with screw threads. The utility model adopts special sealing ring and plug screw for fixation and sealing. Thus, the sealing performance is good, and the installment is firm and convenient as well. Moreover, due to that the convex hub is arranged at the end part of the pipeline, the pipe end is no need to be lathed with screw threads, which greatly reduces the thickness of the pipe. The material of the pipe can adopt stainless steel pipe. The steel pipe thickness of the utility model is 1/4 - 1/5 of the traditional using steel pipe thickness.
Description
Technical field
The utility model relates to the structure that a kind of pipeline connects.
Background technique
At present, the plumbing of construction industry employing and the heating steam line overwhelming majority adopt the Q235 galvanized pipe and the malleable cast iron pipe joints of thread seal.This pipeline is easy especially oxidized corrosion in empty G﹠W, thereby working life is short, causes a large amount of wastes of fed sheet of a media.During particularly as the potable water conveyance conduit, also can cause water supply pollution.And the stainless steel pipeline that the thread seal that adopts at chemical industry, food, pharmaceutical industry connects, the thickness minimum requirements of pipe is the 2.75-3 millimeter.In addition, take a lot of work during this thread seal connection, time-consuming, outward appearance is coarse, seals also not too tight.
Summary of the invention
Technical problem to be solved in the utility model just provides a kind of novel pipeline jointing construction, makes it adopt special sealing ring, and is provided with protruding hub at pipe end, has sealingly secure, fastening, install save time, easy, specious characteristics.
Technical problem to be solved in the utility model is realized by following technological scheme: this pipeline connecting device, and it comprises fittings body 1, Stainless Steel Tube 4; Its improvements are that the end of described Stainless Steel Tube 4 is provided with protruding hub 5; Fittings body 1, Stainless Steel Tube 4 and plug screw 3 are fixed seal ring 2 and compress, and fittings body 1 is threaded with plug screw 3.
Above-mentioned pipeline jointing construction, described protruding hub 5 are annular.
Because this pipeline jointing construction has been abandoned traditional thread seal mode, pipe end is not established screw thread, and employing special sealing ring and plug screw are used for fixing and seal, so good seal performance, install firm, easy.And because be provided with protruding hub at pipe end, pipe end also needn't have screw thread by car, thereby can reduce the thickness of pipe greatly, and the material of pipeline all can adopt Stainless Steel Tube, and steel pipe thickness is the 1/4-1/5 of traditional used steel pipe thickness.
Description of drawings
Fig. 1 is a structure sectional view of the present utility model;
Below in conjunction with accompanying drawing the utility model is described in further detail:
See also shown in Figure 1ly, the end of Stainless Steel Tube 4 is provided with convex annular hub 5 among the figure.The pipe end inside of fittings body 1 is provided with internal thread.One end of seal ring 2 is a wedge shape, be enclosed within the end of Stainless Steel Tube 4 after, put into fittings body 1, screw, press solidly with plug screw 3 again.
