Abstract
The invention relates to an axial locking joint of a glass reinforced plastic pipeline. The axial locking joint comprises a bell mouth and a spigot and is characterized in that two O-shaped sealing rings are installed between the bell mouth and the spigot; a glue filling hole is formed on the bell mouth; and resin is filled in the glue filing hole to form a locking sealing ring. According to the invention, by utilizing a resin material which can be rapidly solidified as the locking sealing ring, rapid installation of the glass reinforced plastic pipeline can be realized; simultaneously, axial tension of the glass reinforced plastic pipeline can be born because of bonding strength among the resin, the bell mouth and the spigot; the leakage prevention role can be played; therefore, the axial locking joint has axial constraint; the leakage probability of the pipeline can be reduced; unnecessary thrust mounds can be omitted; and the construction cost and the working times of the pipeline can be reduced; and therefore, the glass reinforced plastic pipeline is applied to being installed in geological variable areas.
Description
Affiliated technical field
The present invention relates to a kind of axial locking device that GRP pipe connects that is used for, particularly relate to a kind of GRP pipe axial locking joint.
Background technique
General GRP pipe single tube effective length 12m when long distance line is installed, adopts pipe joint to connect usually, and seepage very easily takes place.In the existing technology; The joint style of fw frp pipeline has two kinds of axial constraint and non axial constraints; General axial constraint formula joint relatively more commonly used is: two O shape circles connect, but in the practice of construction installation process, this axial constraint formula jointing needs thrust pier and other supporting facility to cooperate; The joint seepage probability that causes because of landform, construction quality and extraneous natural causes is bigger, has had a strong impact on the actual life of pipeline.
Summary of the invention
For overcoming above-mentioned deficiency of the prior art, but the present invention provides a kind of simple installation, reduces pipe joint seepage probability, has the axial locking function, and the GRP pipe axial locking joint installed of suitable geology variable region.
For realizing that the technological scheme that the foregoing invention purpose is taked is:
A kind of GRP pipe axial locking joint comprises bellmouth and socket, it is characterized in that: 2 road O RunddichtringOs are installed between said bellmouth and the socket, have glue filling opening on the bellmouth, pour into resin in this glue filling opening and form the lock sealing ring.
Said glue filling opening is opened on the bellmouth between the 2 road O RunddichtringOs.
The cross section of said glue filling opening is circle or rectangle.
Said glue filling opening bellmouth inwall side is an arc transition.
Said resin is unsaturated polyester resin or the vinyl series plastics that increases quartz flour.
Useful technique effect of the present invention is, but the resin material of utilization rapid solidification of the present invention can be realized the quick mounting of GRP pipe as the lock sealing ring; Simultaneously because the adhesion strength between resin and the joint socket can be born the axial tension of GRP pipe, and play the antiseepage effect, make it to have axial constraint; And reduction pipeline seepage probability; Save some unnecessary thrust piers, reduce pipeline construction expense and man-hour, make GRP pipe adapt to the geology variable region and install.
Description of drawings
Fig. 1 is the structural representation sketch of GRP pipe axial locking joint of the present invention.
Embodiment
GRP pipe axial locking joint of the present invention comprises bellmouth 1 and socket 2, between mouth 1 and socket 2, is provided with 2 road O RunddichtringOs 3.Bellmouth 1 relevant position (promptly between the 2 road O RunddichtringOs 3) has glue filling opening 4, and the cross section of glue filling opening 4 is circle or rectangle, and the bellmouth side is a fillet, and glue filling opening 4 bellmouth inwall sides are arc transition.Thereby pour into resin material in the glue filling opening 4 and form lock sealing ring 5.
Described resin is unsaturated polyester resin or the vinyl series plastics that increases quartz flour, and the adhesion strength of resin and joint socket can be born the axial tension of GRP pipe, and plays the antiseepage effect.
For the Glass Steel Tube joint socket of realizing tight device with lock can bear axial stress fully, carry out the technology reinforcement in the bellmouth and the faucet section of pipeline, on the basis that unidirectional fibre twines, increase hoop fiber strap.
The undeclared part that the present invention relates to is identical with existing technology.
