Description
Technical field
The present invention relates to GRP pipe product technical field, and in particular to a kind of GRP pipe interface structure.
Background technology
Existing fixed length Fw Frp Pipe construction connection is completed by Push-fit, is exactly that directly fixed length is wound
GRP pipe makes a bellmouth, a socket, then is repaired, and technique is very cumbersome.Bellmouth is being docked with socket simultaneously
When easily collide with each other, and GRP pipe is comparatively brittle in itself, is easily damaged after an impact.Prior art passes through
Increase a butt joint ring for metal come two pipelines of transferring, eliminate situation of the two collision, but metal collar be embedded in underground and
Easily it is corroded, thus causes pipe leakage, surface subsidence occurs.
The content of the invention
It is an object of the invention to provide a kind of GRP pipe interface structure, a kind of brand-new fixed length winding of present invention production
Glass reinforced plastic pipe pipeline joint, is directly wrapped with reinforced plastic glass fibre in lips rubber seal, allows it to form an annular overall.
The present invention provides a kind of GRP pipe interface structure, including elastic inner ring, rigid outer shroud and wooden gasket ring, institute
The wooden gasket ring stated is arranged in the elastic inner ring parallel to the radial direction of the elastic inner ring, and described rigid outer shroud is twined

Specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in figure 1, the embodiment of the present invention is wrapped in two craft port outsides of the GRP pipe of docking 1
The elastic inner ring 2 that is fixed and protects for the craft port to GRP pipe 1, it is wrapped in the outside of elastic inner ring 2 and is used for
The rigid outer shroud 3 of lifting interface structure anticorrosive property and lifting interface structure intensity and it is arranged at two docking
It is used to carry out the craft port of GRP pipe 1 in the wood of end buffering and protection between the craft port of GRP pipe 1
Matter gasket ring 4, wooden gasket ring 4 is arranged in elastic inner ring 2 parallel to the radial direction of elastic inner ring 2, in being both elastic inner ring 2
The central shaft of heart axis and the central axes of wooden gasket ring 4 and the radial section of wooden gasket ring 4 perpendicular to elastic inner ring 2
Line, the winding of rigid outer shroud 3 is wrapped in the outside of elastic inner ring 2, and winding parcel is particularly significant, simply inside GRP pipe 1
Elastic inner ring 2 of jumping a queue cannot ensure elastic inner ring 2 and the rigid dense contact of outer shroud 3, which results in underground buried tube
When may result in the GRP pipes 1 of two docking and misplace, cause unnecessary accident, rigid outer shroud 3 is fiberglass
The glass steel ring cap that fiber is constituted.Used by prior art is all metal collar, is embedded in underground and is easily corroded, thus is caused
, there is surface subsidence in pipe leakage.Glass die interface is now used, the generation of such event has been prevented completely.Elastic inner ring 2 is
Lips rubber seal.The outer surface of elastic inner ring 2 and the inner surface melt binding of rigid outer shroud 3.The production of the embodiment of the present invention
Need to be wrapped in fusing point less than the up to elastic inner ring 2 of the elastic inner ring 2 of its Current Temperatures with the reinforced plastic glass fibre of high temperature in technique
Surface produces certain molten condition, is in this condition that reinforced plastic glass fibre is melt together with elastic inner ring 2, produces one to consolidate
Entirety, do so and be advantageous in that rigid outer shroud 3 cannot produce relative movement between elastic inner ring 2, thoroughly eliminate glass
The problem of the dislocation of steel conduit 1.Wooden gasket ring 4 is arranged at the axial middle of elastic inner ring 2.Thus balance interface structure whole
The stress of body.The outer annular diameter of wooden gasket ring 4 is 1.05 ~ 1.15 times of the annular diameters of elastic inner ring 2.The chi of wooden gasket ring 4
Very little control contributes to lift the firmness in connection of elastic inner ring 2 in the proper range, while slightly larger than elastic inner ring 2
Elastic inner ring 2 can be omited jack-up by the size of annular diameters from middle place, reduce the wall thickness of the ring wall of elastic inner ring 2, due to
Elastic inner ring 2 has elasticity, and its intensity is also just improved when wall thickness reduces, and thus improves two GRP pipes
Bonding strength at 1 docking port, eliminate the frequent mode of prior art junction insufficient strength and situation about revealing.
Wrapped up by rigid outer shroud 3 end of elastic inner ring 2.Parcel is advantageous in that and eliminates by rigid outer shroud 3 and bullet
Property the hot spot of the end of interface rings that constitutes of inner ring 2 so that whole interface rings are more difficult to be corroded.Also include being arranged at glass
The butt end oral area 1-1 of the port of glass steel conduit 1, the outer annular diameter of butt end oral area 1-1 and the outer annular diameter of GRP pipe 1
Difference is more than the wall thickness of elastic inner ring 2.The axial length of butt end oral area 1-1 is that the radial surface of wooden gasket ring 4 is outer to rigidity
1.05 ~ 1.2 times of the distance of the port of ring 3.As shown in Fig. 2 when the port of GRP pipe 1 stretch into elastic inner ring 2 to wood
After matter gasket ring 4 offsets, fluid sealant casting portion is provided with the gap between the port of the main body of GRP pipe 1 and rigid outer shroud 3
5.Fluid sealant casting portion 5 is provided with using fluid sealants such as filling glass cements, can thoroughly completely cut off elastic inner ring 2 all with the external world
Contact.
As shown in figure 1, having the ring wall direction to elastic inner ring 2 on the inner surface of the rigid outer shroud 3 of the embodiment of the present invention
Extend to the bullet of the irregular melting bulge-structure 3-1 inside the ring wall of elastic inner ring 2, melting bulge-structure 3-1 and surrounding
The ring wall melt binding of property inner ring 2.Melting bulge-structure 3-1 is both that reinforced plastic glass fibre is pierced into surface thawing at high operating temperatures
The fiber thorn of the lateral wall of elastic inner ring 2, due to the pressure of winding can be increased when processing, this allow for fiber thorn this as
The ruggedized construction that multiple fiber fines are combined into, while ruggedized construction is because be still high temperature when being pierced into this
State, so equally so can not only be strengthened in rigid outer shroud 3 and elasticity from radial direction with the melt binding of elastic inner ring 2
The connection of ring 2, while also add the total body surface area of connection so that firm further lifting, the lifting of the stable degree has
Help lifted GRP pipe 1 connection monolithic stability degree, and irregular direction also increase all directions bear push away
Squeeze the ability of power.Melting bulge-structure 3-1 stretches into the ring wall wall of the maximum length less than elastic inner ring 2 of the ring wall of elastic inner ring 2
Thick 1/3.If it exceeds 1/3 is easy for causing melting bulge-structure 3-1 to be broken, and because elastic inner ring 2 itself is main
Effect be the craft port for using flexible protective GRP pipe 1, even if so continuous more than 1/3 melting bulge-structure 3-1
The flexibility of the contact site of the craft port that can also reduce elastic inner ring 2 and GRP pipe 1 is split, so it is ten to control the size
Divide necessary.
This specific embodiment is only explanation of the invention, and it is not limitation of the present invention, people in the art
Member can make the modification without creative contribution to the present embodiment as needed after this specification is read, but as long as at this
All protected by Patent Law in the right of invention.
