The utility model discloses a kind of seal for pipe joints circle, in O-shaped shape, the front of the sealing ring be equipped with it is a plurality of in a ring, the water shutoff line of projection, be equipped with along the radially connected a plurality of reinforcing line of sealing ring between the multiple tracks water shutoff line, the water shutoff line and the top for reinforcing line are in angular shape.This seal for pipe joints circle is made of oil resistant, corrosion-resistant, age inhibiting butyronitrile rubber, its front is equipped with annular water shutoff line of multiple tracks projection, is equipped between annular water shutoff line and reinforces line.The depressurization phenomenon caused by situations such as pipeline loses garden, contact surface is rough and uneven in surface or grows stammerer phenomenon can be alleviated, play better seal effect, and increase service life.
Description
Technical field
Seal for pipe joints material is the utility model is related to, is specially a kind of seal for pipe joints circle.
Background technology
The junction of the conveyance conduits such as tap water, natural gas, coal gas, thermal energy, petrochemical industry will be carried out using sealing ring
Sealing.Underground pipe network carries out perforate connection branch and is also required to using close in the case of main conduit delivered inside medium is not stopped
Sealing assembly carries out closed.
The sealing ring being commonly used has O-shaped, V-type, U-shaped, XY types etc., since underground piping usage time is grown, is not easy
Safeguarded there is different requirements to sealing ring.Conventional seals circle after long-time, can grow on its surface and stammer in the duct,
Cause to lose sealing performance.
Utility model content
It is difficult the purpose of the utility model is to overcome above-mentioned background technology, there is provided a kind of seal for pipe joints circle.
To reach above-mentioned purpose, the technical solution that uses for：
A kind of seal for pipe joints circle, in O-shaped shape, the front of the sealing ring be equipped with it is a plurality of in a ring, the water shutoff of projection
Line, is equipped between the multiple tracks water shutoff line along the radially connected a plurality of reinforcing line of sealing ring, the water shutoff line and the top for reinforcing line
Portion is in angular shape.
Further, the water shutoff line is 2-4 bars, and the reinforcing line is 3-6 bars.
Further, the sealing ring material is butyronitrile rubber.
Further, the water shutoff line and reinforcing line are integrated with sealing ring body and are connected.
Further, the water shutoff line is spaced set.
Further, the reinforcing line is centrosymmetric setting.
Further, the back side of the sealing ring is equipped with the ring grain in sawtooth or wave-like.
Further, the sealing ring thickness is 25 millimeters, and the wherein projecting height of water shutoff line and reinforcing line is 15 millimeters.
Further, the top wedge angle of the water shutoff line and reinforcing line is 45 degree.
Having the beneficial effect that using the above scheme：This seal for pipe joints circle is by oil resistant, corrosion-resistant, age inhibiting butyronitrile rubber
It is made, its front is equipped with the annular water shutoff line of multiple tracks projection, is equipped between annular water shutoff line and reinforces line.It can alleviate because pipeline loses
Garden, contact surface is rough and uneven in surface or grows the caused depressurization phenomenon of situations such as stammering phenomenon, plays better seal effect, and increase
Add service life.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model seal for pipe joints circle.
Fig. 2 is the cross section structure schematic diagram of the utility model seal for pipe joints circle..
In figure, water shutoff line 1, reinforces line 2, ring grain 3.
Embodiment
The utility model is further described with reference to the accompanying drawings and embodiments, but the utility model is not limited only to following implementations
Example, it is anticipated that those skilled in the art are in the case where combining the prior art, and there may be many variations for performance.
Such as Fig. 1 and Fig. 2, a kind of seal for pipe joints circle, in O-shaped shape, the front of the sealing ring be equipped with it is a plurality of in a ring,
The water shutoff line 1 of projection, is equipped with along the radially connected a plurality of reinforcing line 2 of sealing ring, the water shutoff line between the multiple tracks water shutoff line 1
1 and reinforce line 2 top be in angular shape.The water shutoff line 1 is 2-4 bars, and the reinforcing line 2 is 3-6 bars.The sealing loop material
Matter is butyronitrile rubber.The water shutoff line 1 and reinforcing line 2 are integrated with sealing ring body and are connected.The water shutoff line 1 is equidistantly to set
Put.The reinforcing line 2 is centrosymmetric setting.
Further, the back side of the sealing ring is equipped with the ring grain 3 in sawtooth or wave-like.The sealing ring thickness is
25 millimeters, the wherein projecting height of water shutoff line and reinforcing line is 15 millimeters.The water shutoff line and reinforce line top wedge angle be
45 degree.
Bore sealing waterline 1 in 25mm to 50nn is two, and transversely strengthening line 2 is three, and sealing ring One-sided Widths are
20mm.Water shutoff line 1 in 65mm to 80mm is three, and transversely strengthening line 2 is four, and sealing ring One-sided Widths are 30mm.100mm
It is four water shutoff lines 1 above, transversely strengthening line 2 is six, and sealing ring One-sided Widths are 40mm.
The ring grain 3 at the back side of sealing ring and pipe clamp joint face are plane contacts, mutually Nian Jie with pipe clamp sealing grain with bonding agent
Just used after firm, ring grain 3 can strengthen adhesive effect and intensity.
Seal for pipe joints circle is primarily adapted for use in the pipelines such as tap water, natural gas, coal gas, thermal energy, petrochemical industry.And do not stopping
Main conduit medium is sealed only in the case of main conduit delivered inside medium, during perforate branch to use.During perforate, first selection with
Branch's pipe clamp that main conduit and branch's bore are consistent, such as the pipe clamp of 600X300（600 represent main pipeline internal diameter size, and 300
Represent lateral internal diameter size）, the pipe clamp with sealing ring is loaded on upper and lower Ka Lian on supervisor with connection bolt by simultaneously tight
Gu.Branch's bore accordingly attached seal leg is installed on pipe clamp, the mounting opening equipment on valve, valve is closed after the completion of perforate
Tapping equipment is split out, does not stop the construction of the installation lateral in the case of pipeline delivered inside medium this time and terminates.
