Abstract
The utility model provides a pipe joint capable of bearing high pressure. The pipe joint capable of bearing the high pressure comprises a joint body, a pipeline, a nut and a seal sleeve, wherein the joint body and the pipeline are connected with the nut. One face of the nut is provided with threads and is connected with the joint body, and the other face of the nut is provided with a suppressing body; an inner circle end face of the joint body is provided with an inner circular conical surface; the cross section of the seal sleeve is of an arc shape and is provided with a cutting edge; the suppressing body suppresses the cutting edge of the arc-shaped seal sleeve into the inner circular conical surface of the joint body to play a role in sealing. The pipe joint capable of bearing the high pressure can adapt to pipe connection under a high pressure system, and is good in sealing property and convenient to install.
Description
Technical field
The utility model relates to a kind of high-pressure pipe connector that bears.
Technical background
Existing pipe joint, joint form is a lot.The utility model provides a kind of pipe joint, and the pipeline that can adapt in the high-pressure system connects, and comes from the structure of its good seal performance.Simultaneously, this pipe joint is convenient to be made and installs, simple in structure, is a kind of pipe joint that can other extensive use.Except being applied to high-pressure system, low service system also can adapt to.
The model utility content
For realizing the above, the technological scheme that the utility model provides is as follows: a kind of high-pressure pipe connector that bears, and this pipe joint comprises fittings body, pipeline, nut and stuffing box gland, described fittings body, pipeline and nut are connected; Nut simultaneously has screw thread and is connected with fittings body, and one side has press body; Fittings body inner circle end face has internal conical surface; The stuffing box gland cross section is arch, has cutting edge; The cutting edge press-in connector body internal conical surface of this press body compacting arch stuffing box gland forms sealing.
Further, described arch stuffing box gland has exterior arc surface and inner arc surface, the stuffing box gland outside has annular boss, boss is divided into two-part with exterior arc surface, outer arcuate face by nut compacting annular boss and boss one side forms extruding trend, and the cutting edge that another outer arcuate face of boss is connected namely is pressed into the internal conical surface of fittings body.
Further, described stuffing box gland cross section is inverted V-arrangement, and the tip of stuffing box gland is horizontal end face, and a limit of v-seal cover is provided with cutting edge.
This high-pressure pipe connector that bears that the utility model relates to, simple in structure, easily manufactured, need not special processing technique, need not other seal ring, can realize effective sealing.
Description of drawings
Fig. 1 is that the utility model can bear the high-pressure pipe connector structural drawing;
The 1-fittings body; The 2-pipeline; The 3-nut; The 31-press body; The 32-inside groove; The 4-stuffing box gland; 41-outer arcuate face; The 42-boss; The 43-concave profile.
Embodiment
As shown in Figure 1, this pipe joint comprises fittings body 1, pipeline 2, nut 3 and stuffing box gland 4, and described fittings body 1, pipeline 2 and nut 3 are connected; Nut 3 one sides have screw thread and are connected with fittings body 1, and one side has press body; Fittings body 1 inner circle end face has internal conical surface; Stuffing box gland 4 cross sections are arch, have cutting edge; Cutting edge press-in connector body 1 internal conical surface of these press body 31 compacting arch stuffing box glands 4 forms sealing.
Stuffing box gland 4 outer rings have annular boss 42, and boss 42 both sides are outer arcuate face 41; Stuffing box gland 4 inboards are concave profile 43, and this structure forms extruding trend by nut 3 compacting annular boss 42 and a side outer arcuate face, and the cutting edge that another outer arcuate face 41 is connected namely is pressed into the internal conical surface of fittings body 1.This moment, nut 3 should have inside groove 32, held annular boss 42, otherwise will cause undue extruding, and stuffing box gland 4 distortion are excessive, lose effect.
Stuffing box gland 4 cross sections are inverted V-arrangement, and the tip of stuffing box gland 4 is horizontal end face, and a limit of v-seal cover 4 is provided with cutting edge.Stuffing box gland 4 outer side surfaces and inner side surface can be arc shaped surface, also can be for facing directly, and the material of sealing cover 4 is metal material, has certain intensity and toughness reguirements.
This high-pressure pipe connector that bears that the utility model relates to can adapt to the high-pressure system lower pipeline and connect, good seal performance, and it is also convenient to install.
Embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the present utility model.
