Description
Technical field
This utility model relates to a kind of GRP pipe, is specifically related to a kind of mine water supply and sewage GRP pipe.
Background technology
Underground coal mine water quality Acidity of Aikalinity is high, corrosivity is strong, use bad environments, metal pipe material uses requirement because it lures erosion property can not meet it, therefore occurs in that mining glass reinforced plastic pipe and plastic tube etc., and glass reinforced plastic pipe and plastic tube self have preferable humidity, non-scaling, the feature of length in service life.
But, in practice, it has been found that existing GRP pipe in use equally exists certain defect.(1) bayonet joint or flange form is generally used to connect between adjacent glass steel conduit, bayonet joint is firm not, and flange form connects needs to use multiple bolt, installs operation inconvenience, and the sealing of two kinds of connected modes is the most poor, easily causes pipe leakage.(2) anti-pressure ability of existing GRP pipe is poor, and intensity is low, and service life is short.
Utility model content
The purpose of this utility model is the defect overcoming above-mentioned prior art, it is provided that a kind of easy for installation, is connected firmly, good seal performance, and anti-pressure ability is strong, the mine water supply and sewage GRP pipe of aging resistance, length in service life.
For this, this utility model provides a kind of mine water supply and sewage GRP pipe, including many GRP pipes, connected by box cupling between adjacent glass steel conduit, GRP pipe two ends outer wall is respectively provided with external screw thread, box cupling inwall is provided with the female thread matched with external screw thread, and the end of adjacent glass steel conduit is offseted in box cupling and sealed by O-ring seal between the two；
GRP pipe in this utility model is connected by box cupling, and box cupling uses with GRP pipe and threadeds, and between GRP pipe, use O-ring seal end seal, first GRP pipe one end is screwed in box cupling, again O-ring seal is put into box cupling, then by another GRP pipe screw-in box cupling until propping up previous glass steel conduit, two GRP pipes by O-ring seal compression thus reach sealing purpose.
Further, described GRP pipe is multiple structure, including inner liner the most compressed together, winding layer and outer surface layer；The composite bed that described inner liner is made up through lamination of scrim layer, fiberglass surfacing mat and glass fibre knitting felt；Described winding layer is the composite bed being composited with epoxy resin substrate with the winding angle of 55 °-65 ° by reinforced plastic glass fibre；Described outer surface layer is the coat being made up of resin and antistatic agent.The antistatic agent used is graphite or white carbon black.
This GRP pipe uses multiple structure, and intensity is high, aging resistance, anticorrosion and antistatic.
Further, the fire prevention composite bed being located between winding layer and outer surface layer is also included.Fire resistance is preferable, will not burn because running into naked light, can be placed on safely outdoor, improve safety.
As preferably, described fire prevention composite bed includes flame-retarded resin layer and the fire prevention layer of cloth being arranged between described flame-retarded resin layer and described winding layer.
As the further improvement in structure, the outer surface of described box cupling is provided with anti-skidding ring-type rib, it is simple to box cupling and GRP pipe are connected.
The beneficial effects of the utility model: this mine water supply and sewage GRP pipe that this utility model provides, simple in construction, easy for installation, it is connected firmly, good seal performance, and anti-pressure ability is strong, aging resistance, service life are long.

Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, it is further elucidated with this utility model.
Embodiment:
Such as Fig. 2, a kind of mine water supply and sewage GRP pipe shown in 3 and 4, including many GRP pipes 1, connected by box cupling 2 between adjacent glass steel conduit 1, GRP pipe 1 two ends outer wall is respectively provided with external screw thread 4, box cupling 2 inwall is provided with the female thread 5 matched with external screw thread 4, and the end of adjacent glass steel conduit 1 is offseted in box cupling 2 and sealed by O-ring seal 3 between the two；
GRP pipe 1 in this utility model is connected by box cupling 2, and box cupling 2 uses with GRP pipe 1 and threadeds, and between GRP pipe 1, use O-ring seal 3 end seal, first GRP pipe 1 one end is screwed in box cupling 2, again O-ring seal 3 is put into box cupling 2, then another GRP pipe 1 being screwed in box cupling 2 until propping up previous glass steel conduit 1, O-ring seal 3 is compressed thus reaches sealing purpose by two GRP pipes.
Further, described GRP pipe 1 is multiple structure, as it is shown in figure 1, include inner liner 1.3, winding layer 1.4 and outer surface layer 1.1 the most compressed together；The composite bed that described inner liner 1.3 is made up through lamination of scrim layer, fiberglass surfacing mat and glass fibre knitting felt；Described winding layer 1.4 is the composite bed being composited with epoxy resin substrate with the winding angle of 55 °-65 ° by reinforced plastic glass fibre；Described outer surface layer 1.1 is the coat being made up of resin and antistatic agent.The antistatic agent used is graphite or white carbon black.This GRP pipe uses multiple structure, and intensity is high, aging resistance, anticorrosion and antistatic.
