Abstract
The utility model belongs to the technical field of pipe connection, in concrete to a sealing element used for pipe connection. Main body of the sealing element comprises a basic contact strip, receiving contact strip and a back contact strip; the basic contact strip and the receiving contact strip are in an angle of beta. When the utility model is installed and used, the sealing element is first installed on an inner pipe and then extruded and pinned by a pipe mounting machine. The utility model obtains the purpose of satisfying the requirement of middle or high pressure pipe sealing. Compared with the prior art, the utility model has scientific and reasonable structural design; the sealed working pressure can reach 5-10 MPa. The utility model makes the connection of the middle or high pressure pipe realize lowest in fabrication cost and most simple in construction method.
Description
The utility model belongs to the Pipe jointing part technical field, is specifically related to a kind of pipeline socket joint, butt joint connection and other facilities, equipment of being used for a kind of Sealing that prevents seepage is installed.
The design principle of public O-ring seal mainly is the elastoplasticity of utilizing cushion rubber itself intrinsic, the purpose that extrudability reaches sealing.There are many factors may make this class cushion rubber reduce sealability, the back causes the jointing insertion end because of other factors wriggling etc. is finished in the rotation of cushion rubber or displacement, construction when the depth that these factors comprise that the pipe internal pressure raises, the jointing insertion end is inserted during construction, pipeline socket joint, and can only be used for the socket joint connection of low pressure tubing.Mesohigh tubing can only adopt other connecting means because the safety coefficient of existing rubber sealing is lower, but the cost height, the construction trouble is unfavorable for continuing to promote.
The utility model overcomes the deficiencies in the prior art part and a kind of reasonable in design is provided, and cost is low, and is easy to install, the variable Sealing of many touch articles of significant sealing affection.
The utility model is to realize like this, the variable Sealing of many touch articles includes seal body, it is characterized in that seal body is made of with back of the body touch article the touch article of meeting that links to each other with basic touch article, basic touch article is the β angle with the angle of meeting touch article, and the β angle can be made in ° scope of 0＜β＜90.The utility model adopts the elastoplasticity of rubber material itself and the variable principle of structural design shape, make Sealing in installation process, can adapt to the requirement of sealing automatically, make Sealing in running, can adapt to the wriggling of jointing insertion end automatically, reach the purpose that strengthens sealing effect.
The touch article of meeting of the present utility model can be made into many according to purposes and user mode, increases sealing effect.
Seal body of the present utility model also can be made of with the touch article of meeting that links to each other basic touch article, and this shape and structure is when seal body is wider, and basic touch article replaces back of the body touch article can play the effect of back of the body touch article equally.
Description of drawings:
Fig. 1 cross-sectional view of the present utility model
Fig. 2 many cross-sectional view of meeting touch article of the present utility model
Fig. 3 for the utility model by basic touch article with meet the seal body cross-sectional view that touch article constitutes
Fig. 4 is a mounting point of the present utility model schematic representation
Label declaration:
1, basic touch article 2, meet touch article 3, the back of the body touch article 4, tubing 5, Sealing
2 couples of embodiments do further detailed description with reference to the accompanying drawings, the variable Sealing 5 of many touch articles is made up of with back of the body touch article 3 basic touch article 1 and the coupled touch article 2 of meeting, the wide section of base touch article 1 is close with the flute profile size in principle, base contact 1 is 60 ° with the angle of meeting contact 2, meet touch article and respectively design one as shown in Figure 1 with back of the body touch article, when installing and using, at first some Sealings 5 are contained on the interior tubing, then adopt the tube filling machine extruding, peg graft and get final product, warp is at 1500 meters of the town water supply project installation, after trying out in 315 millimeters double-wall corrugated pipes of φ, 268 joints try the water and nowhere leak under the working pressure of 1.5MPa, thereby the working pressure that has reached the bearing capacity of joint and corrugated pipe is synchronous, has improved the utilization efficiency of bellows greatly.
The utility model compared with prior art has the following advantages:
1, sealing property at double in addition several times improve, not only improved the reliability of seal, simultaneously Also make mesohigh tubing be connected to become reality with cushion rubber, and cheap construction is easy, no matter has overcome At home still in the world, only be applicable to low pressure tubing with the cushion rubber connecting pipe, and mesohigh tubing Connection must use other interconnection technique or by means of the cost height that other auxiliary material cause, execute The disadvantages such as worker's trouble. The invention of the variable seal of multiple contact has realized the connection of mesohigh tubing Low cost and the combination of simple construction.
The wriggling that 2, can adapt between pipe joint place flared end inwall and the insertion end outer wall is displacement. Not only solved interface and produced the problem of seepage because of the wriggling between the inside and outside wall, and can make pipe The road rigid interface all becomes flexible interface, greatly improves the safety coefficient of engineering.
3, be widely used in comprising that pipe of cement is connected the connection of nonmetal pipeline with plastic tube. Also suitable Be used for the connection of metallic conduit, simultaneously, also can be applicable to the sealing of other non-pipe-line equipment.
Claims (4)
1, the variable Sealing of a kind of many touch articles includes seal body, it is characterized in that seal body by link to each other with basic touch article (1) meet touch article (2) and back of the body touch article (3) constitutes, basic touch article (1) is the β angle with the angle of meeting touch article (2).
