Abstract
The present invention is a kind of double containment assembling pipe joint, the double containment assembling pipe joint includes the first pipe, the second pipe, the first sealing ring, the second sealing ring, second tube end is equipped with thread segment, the thread segment is screwed with first pipe one end internal and external threads and is connect, and first pipe is screwed with second pipe crimps the first crimping of formation anchor ring, the second crimping anchor ring.It has the beneficial effect that：So that the sealing performance of pipeline is better, the service life is longer.
Description
Technical field
The present invention relates to pipe technology fields, and in particular to double containment assembling pipe joint.
Background technology
The sealing performance of existing pipeline is relatively good, but after long-time service or can lead to sealed ring deformation, close
Sealing property reduces, it is therefore desirable to provide that a kind of sealing performance is more lasting, and the new type sealing device of favorable sealing property.
Invention content
The present invention provides a kind of double containment assembling pipe joint, purposes of design：So that the sealing performance of pipeline is better,
The service life is longer.
Scheme is as follows：A kind of double containment assembling pipe joint, the double containment assembling pipe joint include the first pipe 1, the
Two pipes 2, the first sealing ring 3, the second sealing ring 4,2 end of the second pipe are equipped with thread segment 5, the thread segment 5 and described the
One pipe, 1 one end internal and external threads screw connection, first pipe 1 screwed with second pipe 2 crimp the first crimping of formation anchor ring 6,
Second crimping anchor ring 7, first sealing ring 3 are embedded at the first crimping anchor ring 6, and second sealing ring 4 is embedded and institute
State the second crimping anchor ring 7, first sealing ring 3, the second sealing ring 4 truncation surface shape be in the convex umbilicate I-shaped in edge
Type.
Beneficial effects of the present invention are as follows：First pipe 1 is screwed with second pipe 2 crimps formation the first crimping anchor ring
6, second crimping anchor ring 7, first sealing ring 3 be embedded at it is described first crimping anchor ring 6, second sealing ring 4 be embedded with
The second crimping anchor ring 7, design in this way form the dual-seal of inner and outer wall.First sealing ring 3, second
The truncation surface shape of sealing ring 4 is convex umbilicate I-shaped in edge.When first sealing ring 3, the second sealing ring 4 are pressurized
When, the rubber material of edge convex is squeezed to medial concavity so that this sealing ring uniform force plays the work that compensation edge is damaged
With.Because normal conditions lower seal at first by the position aoxidized be marginal position, and the application thickeied edge enhancing it is close
The intensity of seal.For material saving, the application enhances there is no whole, but enhances marginal position.Sealing is fully provided
The enclose and service life.So that the sealing performance of pipeline is better, the service life is longer.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Fig. 2 is the truncation surface figure of first sealing ring 3.
Fig. 3 is the truncation surface figure of second sealing ring 4.
Specific implementation mode
Below in conjunction with attached drawing, the invention will be further described with specific embodiment.
In Fig. 1,2,3：First pipe 1, the second pipe 2, the first sealing ring 3, the second sealing ring 4, thread segment 5, the first crimp rings
Face 6, second crimps anchor ring 7.
A kind of double containment assembling pipe joint, the double containment assembling pipe joint include the first pipe 1, the second pipe 2, first
Sealing ring 3, the second sealing ring 4,2 end of the second pipe are equipped with thread segment 5, in the thread segment 5 and described first pipe, 1 one end
External screw thread screws connection, and first pipe 1 is screwed with second pipe 2 crimps formation the first crimping crimping anchor ring of anchor ring 6, second
7, first sealing ring 3 is embedded at the first crimping anchor ring 6, and second sealing ring 4 is embedded and second crimp rings
Face 7, design in this way form the dual-seal of inner and outer wall.First sealing ring 3, second sealing ring 4 block
Face shape is convex umbilicate I-shaped in edge.
