Abstract
The utility model discloses a kind of flexible grafting sealed steel pipes, including adapting pipe and insertion pipe, the junction of adapting pipe and insertion pipe has the sealing ring using flexible material, sealing ring includes ring body, the outer wall of ring body is equipped with a plurality of annular groove, and the inner wall of ring body is equipped with a plurality of annular protrusion；The inner wall of adapting pipe is equipped with can prevent sealing ring from deviating from the matched protrusion of annular groove, annular groove with the male cooperation accepted on inside pipe wall.The flexible grafting sealed steel pipe of the utility model by adopting the above technical scheme, has both sealing performance and anticreep performance.
Description
Technical field
The utility model relates to pipe fitting technical field more particularly to a kind of flexible grafting sealed steel pipes.
Background technique
In China's long range, the construction of heavy caliber aqueduct, the tubing used is mainly that pre-stress steel cylinder is mixed
Solidifying soil pipe (PCCP pipe), ductile iron pipe, steel pipe, FRP sand tube etc.；Wherein, PCCP pipe and ductile iron pipe
It occupies an leading position, steel pipe dosage is less.The main reason for steel pipe accounting in waterline is less is the connection shape of buried steel pipe
The method that formula generallys use field joint weldering, since water conveyance steel tube relative aperture is big, radius-thickness ratio is big, nozzle is rigidly low, ovality
Greatly, it causes steel pipe docking difficult, is easy welding defect.In addition, tube bottom welds operation difficulty due to the limitation of pipe canal digging
Greatly, to the more demanding of construction personnel.Water conveyance steel tube big for bore, radius-thickness ratio is big, this connection type work efficiency of butt welding
Low, quality is relatively difficult to guarantee.
Currently, the domestic water conveyance steel tube spigot-and-socket flexible joint occurred, sets between steel pipe bellmouth and steel pipe socket
The cushion rubber that interface is the shapes such as rectangular, round is set, by the compressive deformation of cushion rubber, realizes and holds by the elasticity of cushion rubber
Spigot seal connects without rigid solder, efficiently solves the above problem.But since tube fluid acts on cushion rubber, sealing
Limited capacity.
The utility model patent that number of patent application is 201720647725.9 discloses a kind of steel pipe spigot-and-socket flexible joint,
Sealing performance is increased, but anticreep effect is poor.
Utility model content
The technical problems to be solved in the utility model is to overcome above-mentioned technical problem to provide one kind and having both leakproofness
It can be with the flexible grafting sealed steel pipe of anticreep performance.
To solve the above problems, the utility model uses following technical scheme: a kind of flexibility grafting sealed steel pipe, including
The junction of adapting pipe and insertion pipe, adapting pipe and insertion pipe has the sealing ring using flexible material, and sealing ring includes annular
Ontology, the outer wall of ring body are equipped with a plurality of annular groove, and the inner wall of ring body is equipped with a plurality of annular protrusion；Adapting pipe
Inner wall be equipped with the matched protrusion of annular groove, annular groove and accept inside pipe wall on male cooperation can prevent sealing ring
Abjection.
The flexible grafting sealed steel pipe of the utility model by adopting the above technical scheme, has both sealing performance and anticreep performance.
The technical solution of the utility model is described further with reference to the accompanying drawing.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model；
Attached drawing 2 is the structural schematic diagram of sealing rubber ring in the utility model.
In figure: 1- insertion pipe；2- adapting pipe；3- sealing ring；301- ring body；302- annular protrusion；303- annular is recessed
Slot.
Specific embodiment
Embodiment, as shown in Figure 1 and Figure 2, a kind of flexibility grafting sealed steel pipe, including adapting pipe 2 and insertion pipe 1, adapting pipe
2 and insertion pipe 1 junction have using flexible material sealing ring 3, sealing ring 3 include ring body 301, ring body
301 outer wall is equipped with a plurality of annular groove 303, and the inner wall of ring body 301 is equipped with a plurality of annular protrusion 302.
The inner wall of adapting pipe 2 be equipped with the matched protrusion of annular groove 303, on annular groove 303 and 2 inner wall of adapting pipe
Male cooperation can prevent sealing ring from deviating from, sealing ring 3 uses flexible material, while annular protrusion 302 is arranged, so that insertion pipe
1 can all around be angularly offset in adapting pipe 2, facilitate installation.
Claims (1)
1. a kind of flexibility grafting sealed steel pipe, including adapting pipe (2) and insertion pipe (1), it is characterised in that: adapting pipe (2) and insert
The junction for taking over (1) has the sealing ring (3) for using flexible material, and sealing ring (3) includes ring body (301), and annular is originally
The outer wall of body (301) is equipped with a plurality of annular groove (303), and the inner wall of ring body (301) is equipped with a plurality of annular protrusion
(302)；The inner wall of adapting pipe (2) is equipped with and annular groove (303) matched protrusion, annular groove (303) and adapting pipe (2)
Male cooperation on inner wall can prevent sealing ring from deviating from.
