The glass fiber reinforced plastic pipe has the advantages of excellent chemical corrosion resistance, light weight, high strength, no scaling, strong shock resistance and the like, and is accepted by the wide range of users. In the process of laying the pipeline, the glass fiber reinforced plastic pipeline is usually connected in a flange butt joint mode, the bolt screwing time is long, and the working efficiency is not high.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the technical problem that the connection of the traditional glass fiber reinforced plastic pipeline in a flange butt joint mode is long in time consumption is solved.

The utility model provides a screw connection type fiber reinforced plastic pipeline, which comprises a first fiber reinforced plastic pipeline provided with a first outward flange and a second fiber reinforced plastic pipeline provided with a second outward flange;

an annular groove is formed in the first flanging connecting surface, and a sealing ring is arranged in the annular groove;

the first outward turning edge is clamped with a first connecting piece, and the second outward turning edge is clamped with a second connecting piece;

the first connecting piece and the second connecting piece are fixedly connected in a threaded connection mode.

The first connecting piece is in threaded connection with the second connecting piece, and drives the first flanging and the second flanging to be compressed tightly, so that the first glass fiber reinforced plastic pipeline and the second glass fiber reinforced plastic pipeline are butted and sealed through a sealing ring; the utility model discloses simple structure, the simple operation, work efficiency is high.

Furthermore, a first concave table is arranged on one side, connected with the first flanging, of the first connecting piece, and a first gasket is arranged in the first concave table; and a second concave table is arranged on one side of the second connecting piece connected with the second outer flanging, and a second gasket is arranged in the second concave table. The first connecting piece is connected with the first flanging in a clamped mode through the first gasket, the second connecting piece is connected with the second flanging in a clamped mode through the second gasket, and the flanging is protected from being damaged.

Furthermore, the inner ring of the sealing ring is wrapped with a metal layer. When the sealing ring deforms due to sealing, the metal layer is in contact with liquid in the glass steel pipeline, the sealing ring is protected from being polluted, and the service life of the sealing ring is prolonged.

Further, the perimeter of the cross section of the metal layer is less than one half of the perimeter of the cross section of the sealing ring. When the sealing ring is deformed, if the metal layer is damaged, the sealing ring can also play a role in sealing, and the sealing effect of the glass fiber reinforced plastic pipeline is kept.

Furthermore, the first flanging connecting surface is provided with a plurality of first key grooves, the second flanging connecting surface is provided with a plurality of second key grooves corresponding to the first key grooves, and the first key grooves are connected with the second key grooves through flat keys in a clamped mode. The installation and positioning of the glass fiber reinforced plastic pipeline are realized by the mode of clamping the flat key and the key groove, and the connection time of the glass fiber reinforced plastic pipeline is reduced.
