Abstract
The utility model discloses a template straight through pipe joint, comprising a template pipe shaft and connecting flanges which are arranged on the both ends of the template pipe shaft. The template straight through pipe joint is characterized in that the template pipe shaft is a rubber product with a multi-coat cord fabric; the both ends of the template pipe shaft are provided with flanges which are connected with the connecting flanges; the eccentric angle of the shaft lines of the pipe diameters of the both ends of the template pipe shaft is 0 to 8 DEG; a ring groove for receiving the flanges is respectively arranged on one end surface of each connecting flange. The template straight through pipe joint has flexibility and a definite elasticity, which can be convenient to manufacture; the utility model has an eccentric distance.
Description
The utility model is about piping attachment, particularly about the reducing socket of flexible.
In the industrial production, the pipeline of fluids such as the conveying gas of normal distance, liquid uses the reducing coupling pipe joint that the tube coupling of two different-diameters is got up often because of actual demand.Because fluid has higher pressure in carrying the way, these above-mentioned pipe fittings are by the iron and steel manufacturing, lack flexiblely, require the coupling flange dish of adjacent pipe fitting coaxial when mounted.Therefore, not only increased mounting hardness, and in maintenance dismounting in the future,, made above-mentioned defective more apparent outstanding often because of the bending deflection of reducing coupling pipe joint steel pipe that two ends join.Secondly, the pipe fitting of being made by iron and steel is subjected to the influence of temperature, can dilatation.So pipeline Ω ring commonly used is as flexible compensation tache, this increases pipe fitting quantity, has increased the pipeline position that takes up room again.The 3rd, the reducing coupling pipe joint of steel because of making restriction, only is coaxial reducing, can not be fit to the situation that axis has throw of eccentric.
The purpose of this utility model is to provide a kind of and is to provide a kind of and has flexible, certain stretchability and can conveniently make the reducing coupling pipe joint with throw of eccentric.
The purpose of this utility model is achieved in that a kind of reducing coupling pipe joint that comprises the reducing pipe shaft and be arranged on the connecting flange at reducing pipe shaft two ends, it is characterized in that: described reducer is as the rubber product that contains the multilayer hangings lay, the two ends of reducing pipe shaft are provided with the flange that links with connecting flange, and the eccentric angle of reducing pipe shaft two ends caliber axis is 0～80; Be respectively arranged with the annular groove that holds flange on the end face of described each connecting flange.
The utility model will be further described below in conjunction with accompanying drawing.
