The concave-convex type combined flange pipe joint comprises a shrinkable sleeve, a flange 5, a flange 6 and a filling layer, wherein the flange 5 and the flange 6 are symmetrically arranged; the flange 6 comprises an upper flange 7 and a lower flange 8; the shrinkable sleeve is arranged between a steel belt and the lower flange 8; the upper flange 7 is arranged on the outer side surface of the flanging position of a pipe body; the lower end part of the upper flange 7, near the pipe body, is provided with an annular groove; a projection of which radian and depth are matched with the annular groove is arranged on the lower flange 8; the steel belt is arranged between the annular groove and the projection; and the filling layer is arranged in a cavity formed by the steel belt, the pipe body and the upper flange 7. According to the invention, the cost can be reduced by 10%; the pressure bearing capacity can reach more than 6MPa; the tensile yield strength can reach more than 5MPa; and the concave-convex type combined flange pipe joint for connecting composite pipes can effectively enhance the tensile yield strength of a pipeline and has reliability for connection and a long service life.
Description
Technical field
The present invention relates to a kind of composite pipe and connect, belong to the pipe joint technical field, be the superhigh molecular polyethylene compound pipe pipe joint with lenticular Ifold flange pipe joint.
Background technique
In the prior art, one of pipe connecting method is that flange connects, flange connect its advantage be construct at normal temperatures, energy-conservation, but have the shortcoming that tensile yield strength is poor, bearing capacity is low.Variation along with pipeline long-play and external environment factor is applied to flange connections with some distortion power, produces the sealing surface mutual dislocation, seal failure, again owing to variation of ambient temperature, pipeline and connecting bolt produce and expand with heat and contract with cold, cause bolt looseness, cause pipe leakage.
Summary of the invention
The objective of the invention is to overcome the deficiency in the existing flanged joint technology, a kind of " composite pipe connects with lenticular Ifold flange pipe joint " is provided.This pipe joint has reasonable in design, energy-conservation, manufacturing process is simple, installations is easy to connect, anti-impact force is strong, bearing capacity is high advantage, is the composite pipe connection that a kind ofly can effectively improve the pipeline tensile yield strength, connect reliable, long service life with lenticular Ifold flange pipe joint
To achieve these goals, the present invention is achieved through the following technical solutions: a kind of composite pipe connects with lenticular Ifold flange pipe joint, include shrink sleeve, flange 5, flange 6, packed layer, flange 5 is symmetrical arranged with flange 6, described flange 6 is made up of upper flange 7 and lower flange 8, described shrink sleeve places between steel band and the lower flange 8, described upper flange 7 places body flange position outer side surface, underpart at described upper flange 7 close bodys is provided with ring groove, be provided with the projection that is complementary with the ring groove radian and the degree of depth at described lower flange 8, steel band places between ring groove and the projection, and packed layer is arranged at steel band, in body and the upper flange 7 formed cavitys.
Described body 1, body 2 flange position interfaces and body shaft axis are at an angle of 90.
The used material of packed layer is silicon resin glue or one pack system resin glue.
Described upper flange 7 is structure as a whole with ring groove, and described lower flange 8 is structure as a whole with projection.
The used material of described steel band is the Q235 steel.
The present invention compares with existing flange connections joint has following advantage:
1. this pipe joint has reasonable in design, energy-conservation, manufacturing process is simple, installations is easy to connect, anti-impact force is strong, bearing capacity is high advantage, is the composite pipe connection that a kind ofly can effectively improve the pipeline tensile yield strength, connect reliable, long service life with lenticular Ifold flange pipe joint
2. place the steel band outside and coincide, be enclosed within annular shrink sleeve on the body because of being provided with lower flange 8, simultaneously in by steel band, body and upper flange 7 formed cavitys, inject packed layer again, form the double sealing structure, sealing effect is excellent, effectively prevented entering of various source of corrosion, guarantee that lining, steel band and body are not corroded, prolong pipeline working life;
3. the invar band places between groove and the projection, and steel band is by groove and the tight lock of projection, make pipe joint indeformable, do not misplace, not only improved sealability, also effectively improved the pipeline tensile yield strength, tensile yield strength can reach more than the 5MPa;
4. adopt bolton because of the utility model during the pipeline connection, need not thermal source, need not main equipment, work under the normal temperature operating mode, installation and maintenance are extremely convenient, can reduce cost 10%.
