Abstract
The utility model relates to a joint, which comprises a pair of pipelines, cover plates, a gasket and a bolt. A flaring portion is arranged at one end of each pipeline, the gasket is disposed between the two pipelines, a step portion is disposed at each of two ends of the gasket and held in the corresponding flaring portion and is in butt joint with the corresponding flaring portion, the cover plates cover the flaring portions of the pipelines and the gasket, and the bolt penetrates through the cover plates and the gasket to assemble pipe joints together. The pipe joint realizes better sealing performance and difficult leakage of pipelines by the aid of matching of the flaring portions with the step portions and particularly combining surfaces arranged obliquely.
Description
Technical field
The utility model relates to a kind of joint, is specifically related to a kind of sealability joint preferably, belongs to the pipeline connection technology field.
Background technique
The pipeline combination of prior art is shown in Figure of description 1, and it comprises an a pair of pipeline 10,11 and a pipe joint 12.Interior or outer rim in described pipeline 10,11 processes screw thread 101,111, screws togather and pipeline 10,11 is linked together by above-mentioned screw thread 101,111 and pipe joint 12.
Yet the shortcoming of above-mentioned pipeline Placement is: can't seal fully between pipeline 10,11 and the pipe joint 12, when particularly pipeline 10,11 inner fluids produced big pressure, this junction point easily got loose and causes liquid to be revealed.
Therefore, for avoiding above-mentioned technical problem, necessaryly provide a kind of pipe joint, to overcome described defective of the prior art.
The model utility content
For addressing the above problem the joint that the purpose of this utility model is to provide a kind of good seal performance, is difficult for leakage.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of joint, and it comprises a pair of pipeline, cover plate, sealing gasket and bolt, described each pipeline one end is provided with an expansion mouth; Described sealing gasket is located between two pipelines, and its two ends respectively are provided with a stepped part, and described stepped part is contained in the expansion mouth and with expansion mouth and connects; Described cover plate is coated on the expansion mouth and sealing gasket of pipeline; Described bolt-through cover plate and sealing gasket and pipe joint is fitted together; The outer surface of described stepped part is inclined to set.
Compared with prior art, the utlity model has following beneficial effect: joint of the present utility model particularly is provided with the junction plane of inclination by cooperating of expansion mouth and stepped part is set, and makes the sealability of pipeline better, is difficult for revealing.
Description of drawings
Fig. 1 is the schematic representation of the pipeline combination of prior art.
Fig. 2 is the sectional view of joint of the present utility model.
Embodiment
See also shown in Figure 2ly, the utility model is a kind of joint, and it comprises a pair of pipeline 2,3, cover plate 5, sealing gasket 4 and some bolts 7.Wherein, described each pipeline 2,3 one end are provided with an expansion mouth 20,30, and these expansion mouths 20,30 are oppositely arranged.Described sealing gasket 4 is located between two pipelines 2,3, and its two ends respectively are provided with a stepped part 40, and the outer surface of this stepped part 40 is inclined to set, its be contained in the expansion mouth 20,30 and with expansion mouth 20, thereby 30 connect and form a sealing surface.Described cover plate 5 is coated on the expansion mouth 20,30 and sealing gasket 4 of pipeline 2,3.Described bolt 7 runs through cover plate 5 and with sealing gasket 4 pipe joint is fitted together, and borrows the cover plate 5 sealed pressure that produce that expansion mouth 20,30 and stepped part 40 are compressed and reaches the effect of sealing fully.
Joint of the present utility model is by being provided with cooperating of expansion mouth 20,30 and stepped part 40, and the sealing surface that inclination particularly is set increases both area of contact, thereby makes the sealability of pipeline better, is difficult for revealing.
Above embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
