Abstract
The utility model discloses a pipeline is with novel sealing joint, including connecting the body, the both ends that connect the body are connecting tube respectively, connect the body middle part and set up the boss along outer fringe circumference, the joint body of boss both sides is sealed end, sealed end is constructed for the taper pipe screw thread, set up the internal thread in the link of pipeline so that it with the taper pipe screw thread constitutes sealing connection, the boss with the junction of sealed end still sets up the sealing washer. This application forms hard seal through setting up taper pipe screw thread and pipeline internal thread, forms the extrusion simultaneously to the sealing washer through inclined plane chamfer, boss and sealed end and forms soft seal, realizes the structural style of double containment, can not take place the seepage, strengthens sealed effect.
Description
Technical Field
The utility model relates to a sealing for pipe technique field specifically is a novel sealing joint is used to pipeline.
Background
In the connection process of gas, liquid or gas-liquid mixed medium pipelines, a sealing joint is usually used, the sealing connection between the existing sealing joint and the pipelines is generally welded, but in some working occasions where fire is not allowed, the pipeline connection cannot be welded, and the pipeline connection is easy to leak by adopting a simple mechanical sealing mode, so that a good sealing effect cannot be achieved.
SUMMERY OF THE UTILITY MODEL
For solving prior art's not enough, this application provides the sealing joint who does not need the operation of starting a fire, and concrete scheme is as follows: the utility model provides a pipeline is with novel sealing joint, includes the joint body, the both ends of connecting the body are connecting tube respectively, connect the body middle part and set up the boss along outer fringe circumference, the joint body of boss both sides is sealed end, sealed end is constructed for the taper pipe screw thread, set up the internal thread in the link of pipeline so that it with the taper pipe screw thread constitutes sealing connection, the boss with the junction of sealed end still sets up the sealing washer.
Furthermore, the external thread on the taper pipe thread is arranged along the end part of the joint body in the direction of the boss, and an installation gap for installing the sealing ring is reserved between the external thread and the boss.
Further, the connecting end of the pipeline forms a first extrusion surface, and the first extrusion surface is abutted to the sealing ring.
Further, the first extrusion surface is an inclined chamfer which is formed inwards along the end wall of the pipeline.
Furthermore, the surface of the mounting gap on the sealing end is a second extrusion surface, the connection surface of the boss and the sealing end is a third extrusion surface, and the third extrusion surface is perpendicular to the second extrusion surface.
Further, the diameter of the boss is larger than that of the pipeline.
The application has the advantages that: the pipeline that provides forms hard seal with the pipeline internal thread through setting up the taper pipe thread, forms the extrusion to the sealing washer simultaneously through inclined plane chamfer, boss and sealed end and forms soft seal, realizes the structural style of double containment, can not take place the seepage, strengthens sealed effect.
Drawings
Fig. 1 is a schematic view of a connection structure of the novel sealing joint for the pipeline and the pipeline.
Labeled in the figure as: 10. the joint comprises a joint body 101, a second extrusion surface 11, a pipeline 111, a first extrusion surface 12, a boss 121, a third extrusion surface 13 and a sealing ring.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the embodiment provides a novel sealing joint for pipeline, including connecting body 10, connect the both ends of body 10 and be connecting tube 11 respectively, connect and set up the through-hole that runs through in the body and be used for the intercommunication pipeline, connect the body middle part and set up boss 12 along outer fringe circumference, the joint body of boss 12 both sides is sealed end, and sealed end is constructed for the taper pipe screw thread, sets up the internal thread in the link of pipeline 11 so that it constitutes sealing connection with the taper pipe screw thread, and the boss still sets up sealing washer 13 with the junction of sealed end.
Specifically, the external thread on the taper pipe thread is arranged along the end of the joint body 10 in the direction of the boss 12, an installation gap for installing the seal ring 13 is reserved between the external thread and the boss, and the seal ring 13 is an O-shaped seal ring.
Specifically, a first extrusion surface 111 is formed at the connection end of the pipe 11, the connection end is the end connected with the joint body, the first extrusion surface 111 is an inclined chamfer formed inwards along the end wall of the pipe, the space between the inclined chamfer and the installation gap on the sealing end is used for installing a sealing ring, the first extrusion surface 111 abuts against the sealing ring 13, the surface on the sealing end where the installation gap is located is a second extrusion surface 101, the connection surface with the sealing end on the boss 12 is a third extrusion surface 121, the third extrusion surface 121 is perpendicular to the second extrusion surface 101, the first extrusion surface 111, the second extrusion surface 101 and the third extrusion surface 121 jointly form a right-angled triangle structure, and the sealing ring is jointly extruded.
To achieve the sealing effect, the diameter of the boss 12 is larger than the diameter of the pipe 11.
The working principle is as follows: after the sealing structure is screwed with the pipeline, the internal thread of the pipeline 11 is meshed with the external thread on the joint body 10 to form hard sealing, and meanwhile, the sealing ring forms soft sealing under the common extrusion of the first extrusion surface 111, the second extrusion surface 101 and the third extrusion surface 121, so that the double-sealing structural form is realized, and the sealing effect is enhanced.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
