Description
[technical field]
The utility model relates to connect the component of water pipe more particularly to a kind of seal ring assembly for connecting two water pipes.
[background technique]
In previous installation process, sealing ring selects the rubber ring of O-shaped section to be sealed, and the internal diameter of O-ring wants small
In the groover rot diameter of pipeline, the matched cushion rubber of more bigbore pipeline is thicker, and installation, which expends very big manpower, to draw O-ring
It stretches.It covers on pipeline, it is complete during installation to be sealed by squeezing cushion rubber, difficulty is promoted, it can not also accurate control sleeve and pipe
Road same core degree, it is easy to cushion rubber extrusion shearing be destroyed, or release mounting groove.
It can be seen that providing the problem of a kind of improved sealing ring is this field urgent need to resolve.
[utility model content]
The utility model installs time saving and energy saving, good seal performance in view of the above-mentioned problems, provide a kind of seal ring assembly.
To solve the above-mentioned problems, provided by the utility model a kind of for connecting the seal ring assembly of two pipelines, institute
Seal ring assembly is stated with sealing ring, casing, the sealing ring is installed on the inner surface of described sleeve pipe, and described sleeve pipe is connected to two
The both ends of a pipeline, the inner surface of the sealing ring are zigzag, and the sawtooth of the sealing ring, which has, guides the pipeline to enter
The guide portion of described sleeve pipe.
Further, the sawtooth of the sealing ring is tilted to the same direction, and the inclined direction of the sawtooth is with the pipe
The direction that road enters described sleeve pipe is consistent.
Further, there is limited block, the sealing ring is circular ring shape, has limit inside described sleeve pipe inside described sleeve pipe
Position block, the limited block are located on the inner periphery of described sleeve pipe, and the quantity of the limited block is at least 1.
Further, the direction of the thickness of the sealing ring toward limited block becomes larger, the sealing of the limited block two sides
It is contrary to enclose thickness change.
Further, the outer surface of the sealing ring is corrugated, the distance of the undulatory highest point to minimum point
For 0.5mm to 2.5mm.
Further, the length of the sealing ring is 15mm to 45mm.
Further, the tooth of the sawtooth a height of 3mm to 9mm.
Further, the quantity of the sawtooth is 2 to 8.
Further, the inner peripheral surface of described sleeve pipe has groove, and the sealing ring is installed in the groove, the sawtooth
At least part exceed the groove end face.
Further, the sealing ring is round table-like.
Furthermore the sawtooth in the utility model on sealing ring sealing ring existing by pipeline to squeeze with casing close
Feng Li, when water enters pipeline, water squeezes sealing ring from the position of limited block to two sides, so that the sealing that pipeline internal pressure supports outward
Power, forms that internal pressure is bigger, the better benign cycle of sealing effect, while the sawtooth of sealing ring has multiple, adds sealing effect
By force.There is guidance part in sealing ring, so that when in pipeline sleeve pipe, guidance part conduit sleeve pipe.Zigzag may be used also
It is time saving and energy saving to reduce resistance when pipeline promotes, so that casing is concentric with pipeline, avoid sealed ring deformation, sealing ring
It is extruded failure by shear.
[Detailed description of the invention]
Fig. 1 is the schematic diagram that the utility model sealing ring is installed on casing.
Fig. 2 is the schematic diagram after the utility model casing and Pipe installing.
Fig. 3 is the section end view drawing of the utility model sealing ring.
[specific embodiment]
Referring to Fig. 1 to Fig. 3, the composed structure of sealing ring in the utility model is given.Sealing ring 1 is installed in casing 2,
Casing 2 is installed on again on pipeline 3.
Sealing ring 1 is circular ring shape, section end face substantially truncated cone-shaped, two end surface symmetrics.By the section of sealing ring come
Specifically describe the shape of sealing ring.Sealing ring has left side 11, right side 12, upper surface 13, lower end surface 14.Sealing ring has
Flexibility, preferably Elastic plastic-rubber, in a free state, left side 11 are parallel to right side 12, and upper surface 13 is waveform, lower end
Face 14 is zigzag, and straight line is horizontal line where the line on sawtooth most vertex, and the height of sealing ring 1 from left to right gradually decreases,
The angle that 1 upper surface of sealing ring and horizontal line are formed is α, and the distance of waveform highest point to the minimum point of upper surface is A, sealing
The length of circle is L, and the length of each sawtooth in lower end surface is I, and the height of each sawtooth is h, and the height of sealing ring is H, and A is
0.5mm to 2.5mm, α be 4.4 ° to 24.4 °, L be 15mm to 45mm, I be 2mm to 8mm, H be 13mm to 23mm, h be 3mm extremely
9mm, the quantity of sawtooth are 2 to 8, and the length of a wave is 2.17mm to 8.17mm.
Casing 2 is circular tube shaped, and sealing ring 1 is installed on 2 inner peripheral surface of casing, and sealing ring 1 is located at the two sides of casing 2, and casing 2 is also
The limited block 4 being located therein is installed, limited block 4 is located inside pipe casing, and is distributed along the even circumferential of casing, limited block
Position of 4 two pipelines being connected of limitation relative to casing, prevents one of pipeline sleeve pipe 2, and another pipeline
It falls off from casing, is not connected firmly so as to cause two pipelines.Sealing ring 1 is located at the two sides of limited block 4, and limited block two
1 axial symmetry of sealing ring of side.The sawtooth of sealing ring exceeds the end face of groove 5, and the outer diameter of sealing ring is greater than the interior of casing further groove 5
Diameter, in this way when sealing ring is installed in casing, the trend that sealing ring is stretched from compressive state toward free state, so that sealing ring
It can be installed in casing.The angle direction of sealing ring is consistent with the direction of propulsion of pipeline, and sealing ring 1 is avoided to be disengaged from the groove.Casing
Interior groove be it is skewed, tilt angle is consistent with the upper surface change direction of sealing ring.Sawtooth on sealing ring to seal
The sealing force for having enclosed existing by pipeline and casing extruding, when water enters pipeline, water is squeezed from the position of limited block to two sides
Sealing ring 1 forms that internal pressure is bigger so that the sealing force that pipeline internal pressure supports outward, the better benign cycle of sealing effect, simultaneously
The sawtooth of sealing ring has multiple, reinforces sealing effect, while having guidance part 15 in first sawtooth of sealing ring right end, makes
When obtaining in pipeline sleeve pipe, guidance part conduit sleeve pipe, zigzag can also reduce resistance when pipeline promotes, and save
Shi Shengli avoids sealed ring deformation so that casing is concentric with pipeline, and sealing ring is extruded failure by shear.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
