Abstract
The utility model discloses a bellows socket joint connects sealing joint, including sealing sleeve, be equipped with on sealing sleeve's the pipe wall in turn with the cyclic annular crest of ripple outer wall complex and the cyclic annular trough of bellows, the outside of cyclic annular crest is equipped with cyclic annular sealed arch. The utility model has the characteristics of fixed strength is high, and sealing performance is good.
Description
Technical Field
The utility model relates to a bellows sealing joint, especially a bellows socket joint connects sealing joint.
Background
The corrugated pipe has various connection modes, the most traditional and simplest mode is a socket type, and plug-in connection is carried out through socket plugs and sockets at the head end and the tail end of the corrugated pipe. The female joint is not fixed by any other structure during connection, and therefore, the female joint is also the one which is the least strong and most likely to fall off or leak in the connection mode.
In order to improve the connection sealing performance of the socket joint as much as possible, a sealing rubber ring is usually arranged at a joint at present, but the existing sealing rubber ring has the problems that the fixing strength between the sealing rubber ring and a corrugated pipe body is not high, and the sealing rubber ring is usually short in arrangement length and not ideal in sealing effect because the outer wall of the corrugated pipe is corrugated.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a bellows socket joint sealing joint. The utility model has the characteristics of fixed strength is high, and sealing performance is good.
The technical scheme of the utility model: the corrugated pipe spigot-and-socket connection sealing joint comprises a sealing sleeve, wherein the pipe wall of the sealing sleeve is alternately provided with an annular wave crest and an annular wave trough which are matched with the corrugated outer wall of the corrugated pipe, and an annular sealing bulge is arranged outside the annular wave crest.
The sealing joint is connected with the corrugated pipe in a socket-and-spigot manner, the sealing sleeve is split into two halves along the axial direction, and the two halves are spliced to form the sealing joint during installation.
In the corrugated pipe spigot-and-socket connection sealing joint, the section of the annular sealing bulge is triangular, and the vertex angle of the triangle is deviated to the side opposite to the insertion direction.
In the corrugated pipe socket joint sealing joint, two annular sealing bulges are arranged on the outer side of each annular wave crest, and the connecting line of the top ends of the two annular sealing bulges is parallel to the axis of the sealing sleeve.
The corrugated pipe is connected with the sealing joint in a socket-and-spigot manner, the annular wave crests and the annular wave troughs are made of hard materials, and the annular sealing bulges are made of flexible sealing materials.
The utility model has the advantages that:
the utility model has the advantages that the sealing sleeve is arranged, the wave crest and the wave trough which are matched with the outer wall of the corrugated pipe are arranged on the pipe wall of the sealing sleeve, and the sealing sleeve is directly clamped on the outer wall of the corrugated pipe during installation, so that the sealing sleeve can not fall off completely during installation, and the fixed strength of installation is greatly improved; and simultaneously, the utility model discloses the biggest benefit is in, is connected the back through seal sleeve and bellows connection end, can ignore the irregular shape of bellows outer wall, according to actual demand extension seal sleeve's length to can prolong the sealed bellied quantity outside the seal sleeve, improve sealed effect.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural view of the structure of fig. 1 mounted on a corrugated pipe.
Description of reference numerals: 1-sealing sleeve, 2-annular wave crest, 3-annular wave trough and 4-annular sealing bulge.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
The embodiment of the utility model provides a:
a corrugated pipe socket joint sealing joint is shown in the attached figures 1-2 and comprises a sealing sleeve 1, wherein annular wave crests 2 and annular wave troughs 3 matched with the corrugated outer wall of a corrugated pipe are alternately arranged on the pipe wall of the sealing sleeve 1, and annular sealing bulges 4 are arranged outside the annular wave crests 2.
When the corrugated pipe sealing device is used, the sealing sleeve 1 is installed and fixed at the socket head end of the corrugated pipe and is inserted into a socket. Sealing sleeve 1 is when the preparation, and the internal diameter size and the shape of cyclic annular crest 2 are unanimous with the external diameter size and the shape of the crest of the outer wall of bellows socket joint head end, guarantee when connecting, sealing sleeve 1 and bellows outer wall in close contact with, in order to improve the compactness of contact, can also scribble sealed glue on the surface of bellows spigot.
Preferably, the sealing sleeve 1 is cut into two halves along the axial direction, the two halves are spliced to form the sealing sleeve during installation, when the sealing sleeve 1 is made of hard plastics or rubber, the sealing sleeve is difficult to be installed on a socket head of the corrugated pipe, a splicing type structure can be buckled on two sides of the socket head respectively to realize installation, and after the socket head is inserted into the socket, the socket head is tightly wrapped, so that the connection strength of the splicing type to the sealing sleeve 1 and the corrugated pipe is not needed to be considered, but in order to improve the sealing effect of the splicing seam, sealant can be smeared at the splicing seam to seal.
Preferably, the cross section of the annular sealing protrusion 4 is triangular, the vertex angle of the triangle is deviated to the opposite side of the inserting direction, when the socket head end is inserted, the annular sealing protrusion 4 with the triangular cross section inclines to the opposite side of the socket head inserting direction, and the outer diameter is reduced, so that the whole socket head can be inserted into the socket, and the outer side wall of the annular sealing protrusion 4 can be tightly attached to the inner wall of the socket under the action of the restoring force of the annular sealing protrusion 4, thereby realizing sealing.
Preferably, two annular sealing bulges 4 are arranged on the outer side of each annular wave crest 2, the connecting line of the top ends of the two annular sealing bulges 4 is parallel to the axis of the sealing sleeve 1, the plurality of annular sealing bulges 4 are arranged in a manner of increasing the number of the annular sealing bulges 4 as much as possible, increasing the number of sealing layers and improving the sealing effect, and the top end of each annular sealing bulge 4 is flush so as to ensure that each annular sealing bulge 4 can have almost the same sealing capacity.
Preferably, the annular wave crests 2 and the annular wave troughs 3 are made of hard materials, the annular sealing bulges 4 are made of flexible sealing materials, the annular wave crests 2 and the annular wave troughs 3 are parts forming the tube body of the sealing sleeve 1, the rigid materials are favorable for improving the connection strength of the sealing sleeve and the corrugated tube, and the flexible sealing materials are adopted for the annular sealing bulges 4 to improve the sealing performance of the sealing sleeve.
The above description is only for the purpose of illustrating the present invention and the appended claims, and the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
