Description
Technical field
The application belongs to section bar accessory technical field, particularly relates to a kind of tube connection piece and pipe connecting structure.
Background technique
Existing pipeline connection is generally material pipeline of the same race and connects, and the connection of such as cast iron tube and cast iron tube, because the pipeline be connected belongs to identical material, its manufacturer's standard is identical, and existing accessory can be adopted can to realize good sealing as pipe collar directly connects.And run into sometimes in engineering need the pipeline of unlike material connect through, the such as connection of Water and Waste Water Engineering medium cast iron pipe and plastics mute pipe, because material is different, cast iron tube is different with the manufacturer's standard of plastics mute pipe, plastics mute pipe nominal diameter is 110mm, its external diameter is of a size of 110mm, the immediate cast iron tube nominal diameter of plastics mute pipe nominal diameter is 109mm therewith, its outside dimension is 109mm, if need above-mentioned two kinds of tubing to connect through, due to the difference of outside dimension, adopt existing pipe collar all cannot realize good sealing, especially in water supply and drainage pipeline, may be that engineering leaves potential safety hazard because of pipeline junction sealing.
Model utility content
In view of the foregoing, the utility model provides the pipe connecting structure of a kind of rubber washer and packing ring formation thus, when its objective is that the pipeline realizing unlike material connects, realizes excellent sealing and good connection.
For achieving the above object, the technical solution of the utility model is:
A kind of rubber washer, comprise washer body, described washer body is the cylindrical shell of two ends internal diameter reducing; End sealing ring, described end sealing annular is formed in described washer body inwall, and is positioned at change place of described washer body internal diameter; Tube wall seal ring, described tube wall seal ring is formed at described washer body inwall, and 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 seal ring is triangle.
Wherein, described rubber washer adopts the cast of Ethylene Propylene Terpolymer material one to form.
The basis of above-mentioned rubber washer is formed a kind of linkage structure, comprises 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 assemblying body of described clip and described rubber washer.
Wherein, described anchor ear is no less than twice.
Compared with prior art, its beneficial effect is the utility model:
First, the rubber washer that the utility model provides, its two ends reducing, can coordinate the fine difference on the unlike material external diameter of two ends, realizes the good laminating between rubber washer and tube wall.
Secondly, be formed at the tube wall seal ring of the inwall of rubber washer, be especially formed at the end sealing ring of two ends internal diameter change sudden change place, can further between link and tube wall and pipe coupling place form excellent sealing.
Moreover, the linkage structure that the application provides, internal layer is flexible seal connector, and overcoat is that the clip of rigidity forms join strength, seal connector, rigid connector and pipeline are connected into entirety by anchor ear by side, and this linkage structure possesses good connectivity and good sealing simultaneously.
Accompanying drawing explanation
Fig. 1 is the sectional view of rubber washer;
Fig. 2 is linkage structure schematic diagram;
Fig. 3 is linkage structure using state figure.
Reference character: 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 tube.
Embodiment
Clearly understand for making goal of the invention of the present utility model, technological scheme and beneficial effect, below in conjunction with accompanying drawing, embodiment of the present utility model is described, it should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.
Be rubber washer sectional view see Fig. 1, Fig. 1, as can be seen from the figure, rubber washer 1 comprises washer body 101, and described washer body 101 is the cylindrical shell of two ends internal diameter reducing; End sealing ring 102, described end sealing annular is formed in described washer body 101 inwall, and is positioned at change place of described washer body internal diameter; Tube wall seal ring 103, described tube wall seal ring 103 is formed at described washer body 103 inwall, and is positioned at described end sealing ring 102 both sides.
In the specific implementation, when rubber washer is used for two pipeline sections connections, for making two pipe end relative positions realize good sealing, form mild transition, the transverse section of described end sealing ring 102 is rectangle.
In the specific implementation, the cross section of tube wall seal ring 103 is triangle.In the present embodiment, the tube wall seal ring 103 of each pipe end is set to twice.
In the specific implementation, for guaranteeing the toughness that rubber washer is good and sealability, described rubber washer adopts the cast of Ethylene Propylene Terpolymer material one to form.
A kind of linkage structure, shown in Figure 2, comprise, rubber washer 1, described rubber washer 1 connects two sections of pipeline sections as interconnecting piece; Clip 2, described clip 2 is nestable in described rubber washer 1 outer wall, and its effect increases coupling stiffness; Anchor ear 3, described anchor ear 3 interval is bound round outside the assemblying body of described clip 2 and described rubber washer 1, and what connect due to this linkage structure is two pipeline sections, and therefore, described anchor ear is no less than twice.
Above-mentioned linkage structure be used for two unlike materials pipeline section connect time embodiment shown in Figure 3, in the present embodiment, the plastics mute pipe 4 of the pipeline section in left side to be nominal diameter be 110mm, its external diameter is 110mm, the cast iron tube 5 of the pipeline section on right side to be nominal diameter be 109mm, its external diameter is 109mm, in building water supply and sewerage engineering, above-mentioned two pipeline sections are needed to connect into through pipeline, the connection procedure of above-mentioned linkage structure is adopted to be: (the plastics mute pipe 4 in left side inserts the larger port of the internal diameter of rubber washer 1 first respectively the cast iron tube 5 on the plastics mute pipe pipe 4 in left side and right side to be inserted simultaneously two ports of rubber washer 1, the cast iron tube 5 on right side inserts the less port of the internal diameter of rubber washer 1, and simultaneously to rubber washer 1 end sealing ring 102 near and finally make the end of plastics mute pipe 4 and cast iron tube 5 abut in the both sides of end sealing ring 102), then at the clip 2 of rubber washer 1 outer wall set metal, finally interval suit anchor ear 3 on the outer wall of clip 2, and the opening of anchor ear 3 passes through screw locking.
Although the mode of execution that the utility model discloses as above, the mode of execution that its content just adopts for the ease of understanding the technical solution of the utility model, is not intended to limit the utility model.Technician in any the utility model art; under the prerequisite not departing from the core technology scheme that the utility model discloses; any amendment and change can be made in the form implemented and details; but the protection domain that the utility model limits, the scope that still must limit with appending claims is as the criterion.
