Seal and pipeline outer wall realize pinch seal by elastic deformation, so as to reach pipeline Butt sealing function.Such a connecting mode,
Often because rubber seal elastic deformation deficiency, cause the sealing property of pipeline it is difficult to ensure that, cause at pipeline birdsmouth exist let out
The hidden danger of leakage.
The defects of existing in view of above-mentioned existing birdsmouth pipe fitting, the design people, is actively subject to research and innovation, to create
If a kind of birdsmouth pipe fitting of new structure, it is set to have more practicality.
Utility model content
The purpose of this utility model is to overcome the defects of mentioned above and deficiency, and provides a kind of fiber cable cement
Pipe.
The utility model realizes that the technical scheme that its purpose uses is as follows.
A kind of spigot-and-socket fibre-cement pipe, including fibre-cement pipe, birdsmouth, interface；The birdsmouth and interface
It is divided into fibre-cement pipe both ends；The birdsmouth diameter is more than the caliber of fibre-cement pipe；The birdsmouth passes through round platform pipe
It is connected with fibre-cement pipe；The fibre-cement pipe suppresses institute's structure by the plant fiber layer of the cement solidifies layer and the M-1 layers of M layers
Into, and M >=2, described plant fiber layer are staggered with the layer that thes cement solidifies, and the inner surface and appearance of the fibre-cement pipe
Face is the layer that thes cement solidifies；The fibre cement pipe outer wall is arranged with spaced rubber ring；External diameter of the rubber ring etc.
In the external diameter of birdsmouth；The birdsmouth end set has inwardly projecting snap ring；The interface outer wall offers depression
Neck；The snap ring is snapped in neck.
The round platform inside pipe wall is provided with bulge loop；The bulge loop is in hollow cylindric；The external diameter of the bulge loop is less than fibre
The external diameter of pipe of cement is tieed up, the internal diameter of bulge loop is more than the internal diameter of fibre-cement pipe；The side wall of the interface is offered in bulge loop phase
The annular groove of adaptation；The length of the bulge loop is 10 ~ 15cm, and the length of bulge loop is less than the depth of groove；The groove
Bottom is embedded with sealing ring；Sealing ring thickness is more than depth of groove plus bulge loop length sum.
This pipeline is in junction using undertaking and snap-in structure, fixed more firm, good airproof performance.This pipeline body multiple tube
Road, improve the intensity of pipeline.The layer that thes cement solidifies of internal layer has good corrosion resistance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：Birdsmouth 1, snap ring 1a, round platform pipe 2, bulge loop 2a, fibre-cement pipe 3, rubber ring 4, interface 5, groove
5a, neck 5b, sealing ring 5c.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in further detail.
A kind of spigot-and-socket fibre-cement pipe, including fibre-cement pipe 3, birdsmouth 1, interface 5；The birdsmouth 1 and insert
Interface 5 is divided into the both ends of fibre-cement pipe 3；The diameter of birdsmouth 1 is more than the caliber of fibre-cement pipe 3；The birdsmouth 1
It is connected by round platform pipe 2 with fibre-cement pipe 3；The fibre-cement pipe 3 is fine by the plant of the cement solidifies layer and the M-1 layers of M layers
Dimension lamination system is formed, and M >=2, described plant fiber layer are staggered with the layer that thes cement solidifies, and the fibre-cement pipe 3
Inner surface and outer surface be the layer that thes cement solidifies；The outer wall of fibre-cement pipe 3 is arranged with spaced rubber ring 4；Institute
The external diameter for stating rubber ring 4 is equal to the external diameter of birdsmouth 1.
The setting of rubber ring 4, play a part of protecting fibre-cement pipe 3, also, accepted when the external diameter of rubber ring 4 is equal to
During the external diameter of mouth 1, spigot-and-socket fibre-cement pipe can lie against ground, be advantageous to the installation of pipeline.The layer that thes cement solidifies plays enhancing
The effect of pipeline strength.Because plant fiber layer is corrodible, therefore, after pipe of cement is scrapped, plant fiber layer meeting spontaneous corrosion,
Pollution will not be produced.
The inwall of round platform pipe 2 is provided with bulge loop 2a；The bulge loop 2a is in hollow cylindric；The external diameter of the bulge loop 2a
Less than the external diameter of fibre-cement pipe 3, bulge loop 2a internal diameter is more than the internal diameter of fibre-cement pipe 3；The side wall of the interface 5 opens up
There is the annular groove 5a being adapted in bulge loop 2a；The length of the bulge loop 2a is 10 ~ 15cm, and bulge loop 2a length is less than recessed
Groove 5a depth；The groove 5a bottoms are embedded with sealing ring 5c；Sealing ring 5c thickness is more than recessed plus bulge loop 2a length sum
Groove 5a depth.
When interface 5 inserts fibre-cement pipe 3, bulge loop 2a is embedded at groove 5a, shape between birdsmouth 1 and interface 5
Into complex fine crack, be advantageous to improve both sealings.Because sealing ring 5c thickness is big plus bulge loop 2a length sums
In groove 5a depth, therefore, sealing ring 5c is in compressive state, favorable sealing property.Even if two trickle dislocation of pipeline, are remained to
Ensure the sealing property of junction.
The end set of birdsmouth 1 has inwardly projecting snap ring 1a；The outer wall of interface 5 offers the neck of depression
5b；The snap ring 1a is snapped in neck 5b.
When interface 5 is inserted in birdsmouth 1, snap ring 1a is snapped in neck 5b, to both fixed connections.
The utility model is illustrated according to embodiment, and on the premise of present principles are not departed from, the present apparatus can also be made
Go out several modifications and improvements.It should be pointed out that all technical schemes obtained using modes such as equivalent substitution or equivalent transformations, are fallen
In the scope of protection of the utility model.
