Road connects through, such as Water and Waste Water Engineering medium cast iron pipe and the connection of plastics mute pipe, due to material not
With, cast iron pipe is different with the manufacturer's standard of plastics mute pipe, and plastics mute pipe nominal diameter is 110mm,
The size of its external diameter is 110mm, with this plastics mute pipe nominal diameter immediate cast iron pipe nominal diameter
For 109mm, its outside dimension is 109mm, if needing to connect through by above two tubing, by
In the difference of outside dimension, use existing pipe collar all cannot realize good sealing, the especially row of feedwater
In waterpipe, may be that engineering leaves potential safety hazard because of pipeline junction sealing.
Summary of the invention
In view of the foregoing, the present invention provides a kind of rubber washer and the pipeline that thus packing ring is formed to connect knot
Structure, when its objective is the pipeline connection realizing unlike material, it is achieved excellent seals and good connection.
For achieving the above object, the technical scheme is that
A kind of rubber washer, including washer body, described washer body is the cylinder of two ends internal diameter reducing；
End sealing ring, described end sealing ring is formed at described washer body inwall, and is positioned at described packing ring originally
At the change of internal footpath；Tube wall sealing ring, described tube wall sealing ring is formed at described washer body inwall, and
It is positioned at described end sealing ring both sides.
Wherein, the transverse section of described end sealing ring is rectangle.
Wherein, the transverse section of described tube wall sealing ring is triangle.
Wherein, described rubber washer uses the one cast of EPDM material to form.
A kind of attachment structure is formed on the basis of above-mentioned rubber washer, including above-mentioned rubber washer, described
Rubber washer connects two sections of pipeline sections as interconnecting piece；Clip, described clip is nestable in described rubber washer
Outer wall；Anchor ear, described anchor ear interval is bound round outside the assembly of described clip and described rubber washer.
Wherein, described anchor ear is no less than twice.
Compared with prior art, it has the beneficial effect that the present invention
First, the rubber washer that the present invention provides, its two ends reducing, can coordinate outside the unlike material of two ends
Fine difference on footpath, it is achieved the good laminating between rubber washer and tube wall.
Secondly, it is formed at the tube wall sealing ring of the inwall of rubber washer, is especially formed at two ends internal diameter and becomes
Change the end sealing ring at sudden change, can be formed between connector and tube wall and at pipe joint further
Excellent sealing.
Furthermore, the attachment structure that the application provides, internal layer is elastic seal connector, and overcoat is rigidity
Clip formed bonding strength, side by anchor ear, seal connector, rigid connector and pipeline are connected into
Entirety, this attachment structure is provided simultaneously with good connectivity and good sealing.
Accompanying drawing explanation
Fig. 1 is the sectional view of rubber washer；
Fig. 2 is attachment structure schematic diagram；
Fig. 3 is that attachment structure uses state diagram.
Reference: 1-rubber washer, 101-washer body, 102-end sealing ring, 103-tube wall seal
Ring, 2-clip, 3-anchor ear, 4-plastics mute pipe, 5-cast iron pipe.
Detailed description of the invention
For making the goal of the invention of the present invention, technical scheme and beneficial effect of greater clarity, below in conjunction with
Embodiments of the invention are illustrated by accompanying drawing, it should be noted that in the case of not conflicting, this Shen
Embodiment in please and the feature in embodiment can mutual combination in any.
Seeing Fig. 1, Fig. 1 is rubber washer sectional view, it can be seen that rubber washer 1 includes
Washer body 101, described washer body 101 is the cylinder of two ends internal diameter reducing；End sealing ring 102,
Described end sealing ring is formed at described washer body 101 inwall, and is positioned at the change of described washer body internal diameter
At change；Tube wall sealing ring 103, described tube wall sealing ring 103 is formed at described washer body 103 inwall,
And it is positioned at described end sealing ring 102 both sides.
In the specific implementation, when rubber washer connects for two pipeline sections, for making two pipe ends real relative to position
The best sealing, forms mild transition, and the transverse section of described end sealing ring 102 is rectangle.
In the specific implementation, the cross section of tube wall sealing ring 103 is triangle.In the present embodiment, each
The tube wall sealing ring 103 of pipe end is set to twice.
In the specific implementation, for guaranteeing toughness and the sealing property that rubber washer is good, described rubber washer
The one cast of EPDM material is used to form.
A kind of attachment structure, shown in Figure 2, including, rubber washer 1, described rubber washer 1 is made
Two sections of pipeline sections are connected for interconnecting piece；Clip 2, described clip 2 is nestable in described rubber washer 1 outer wall,
Its effect is to increase coupling stiffness；Anchor ear 3, described anchor ear 3 interval is bound round in described clip 2 and described rubber
Outside the assembly of rubber gasket 1, connect due to this attachment structure is two pipeline sections, therefore, described anchor ear
No less than twice.
Above-mentioned attachment structure embodiment when the pipeline section of two unlike materials connects is shown in Figure 3,
In the present embodiment, the pipeline section in left side be nominal diameter be the plastics mute pipe 4 of 110mm, its external diameter is
110mm, the pipeline section on right side be nominal diameter be the cast iron pipe 5 of 109mm, its external diameter is 109mm,
In building water supply and sewerage engineering, need above-mentioned two pipeline section is connected into through pipeline, use above-mentioned
The connection procedure of attachment structure is: the most respectively by plastics mute pipe pipe 4 and the cast iron pipe 5 on right side in left side
(the plastics mute pipe 4 in left side inserts the interior of rubber washer 1 to be inserted simultaneously into two ports of rubber washer 1
The port that footpath is bigger, the cast iron pipe 5 on right side inserts the port that the internal diameter of rubber washer 1 is less, and simultaneously
To the end sealing ring 102 of rubber washer 1 near and finally make plastics mute pipe 4 and the end of cast iron pipe 5
Portion abuts in the both sides of end sealing ring 102), then at the clip of rubber washer 1 outer wall set metal
2, finally interval suit anchor ear 3 on the outer wall of clip 2, and the opening part of anchor ear 3 passes through screw locking.
Although disclosed embodiment is as above, but its content is only to facilitate understand the present invention
Technical scheme and the embodiment that uses, be not intended to limit the present invention.Technology belonging to any present invention
Skilled person, on the premise of without departing from disclosed core technology scheme, permissible
The form implemented and details make any amendment and change, but the protection domain that the present invention is limited, still
Must limit in the range of standard with appending claims.
