Description
Technical field
The utility model relates to a kind of flexible connecting device for underground petroleum pipeline, particularly relate to a kind of 3 weakenings by realizing connecting tube containing 20 flexible steel in flat section tubing with outside thread fixed bolt, flexibly connect and seal and be fastenedly connected, by sealing gasket and seal ring connecting tube 2 sealings containing 20 circular holes, belong to the technical research field that petroleum pipeline connects.
Background technique
The easy transmitting vibrations load that is rigidly connected of underground petroleum pipeline, not only damages pipeline, and easily makes two connecting tubes misplace at jointing, cause tube fluid to leak.And if nuisance vibration can be eliminated before being delivered to connected pipe, can available protecting connected pipe, and prevent two pipeline generation relative displacements.
Therefore, easily transmit this problem of nuisance vibration for being rigidly connected of existing petroleum pipeline interface, should consider from pipeline Placement and structure, design and replace the rigidly connected a kind of connection set of pipeline.
Summary of the invention
The utility model easily transmits this problem of nuisance vibration for being rigidly connected of existing petroleum pipeline interface, provides a kind of a kind of flexible connecting device for underground petroleum pipeline that can effectively solve the problem.
A kind of flexible connecting device for underground petroleum pipeline of the present utility model is by the following technical solutions:
A kind of flexible connecting device for underground petroleum pipeline, mainly comprise pipeline, flexible steel in flat section tubing, seal ring, sealing gasket and tightening nut, pipeline is divided into pipeline A and pipeline B, and pipeline A and pipeline B is tightly connected by seal ring, flexible steel in flat section tubing, and is fixed by tightening nut and sealing gasket; The jointing of described pipeline A and pipeline B is provided with protruding end, protruding end face has 20 circular holes; Described flexible steel in flat section tubing is elongate tubular structure, 20 fixed bolts are respectively equipped with in its both ends of the surface, fixed bolt diameter is slightly less than the Circularhole diameter on protruding end face and it is transition fit, and the end of fixed bolt is provided with outside thread, and flexible steel in flat section tubing selects viscoelasticity high-damping rubber material; Described seal ring is " O " shape structure, and its external diameter is identical with pipeline protruding end, and seal ring end has 20 circular holes, and its diameter is identical with the Circularhole diameter on protruding end face, and NBR nitrile rubber selected by seal ring; Described sealing gasket and tightening nut quantity are respectively 20, and sealing gasket is that material is NBR nitrile butadiene rubber with " O " shape structure.
Flexible steel in flat section tubing is designed to the elongate tubular structure of viscoelasticity high-damping rubber material by the utility model, and be respectively equipped with 20 fixed bolts in its both ends of the surface, realize 3 weakenings by this design and flexibly connect, the viscoelasticity namely had by viscoelasticity high-damping rubber and high damping characteristic carry out 3 vibration dampings to the vibration of pipeline.As when pipeline A vibrates, its vibration damping is, the vibrational energy of pipeline A is delivered to fixed bolt, due to the fixing restriction by circular hole on pipeline protruding end face, constraint fixed bolt is moved and makes it be subject to shear action, vibrational energy in fixed bolt is consumed by the mode being converted into heat energy, and is designed to 20 fixed bolts, improve damping efficiency by multizone contact; Secondary vibration damping is, flexible steel in flat section tubing is delivered to through the remaining vibrational energy of fixed bolt, now consume vibrational energy by friction in the viscosity between flexible steel in flat section tubing rubber molecular chain, due to flexible steel in flat section tubing is designed to elongate tubular, be therefore converted to potential energy to consume vibrational energy by its local deformation and kinetic energy again; Three times vibration damping is, remaining microvibration is eliminated by the fixed bolt at pipeline B place, thus ensures that pipeline B is affected by vibration.
The end face of fixed bolt is designed with outside thread by the utility model, and the sealing being realized pipeline by this design is fastenedly connected, namely only need be mounted thereto by tightening nut, by gap and the pretightening force of rotational fastener nut and adjustable Sealing.
The utility model adopts the sealing realizing flexible steel in flat section tubing and pipeline A, pipeline B containing the seal ring of 20 circular holes, prevents tube fluid from leaking; Adopt sealing gasket to realize the fixing seal of fixed bolt and pipeline A, pipeline B, realize the secondary seal of tube fluid and prevent managing outer foreign matter and enter in pipe.
The beneficial effects of the utility model are: realized 3 weakenings of connecting tube by the flexible steel in flat section tubing containing 20 fixed bolts and flexibly connected; The sealing being realized pipeline by the outside thread design of fixed bolt is fastenedly connected; Prevent tube fluid from leaking by the seal ring containing 20 circular holes; Realize secondary seal by sealing gasket and prevent managing outer foreign matter entering in pipe.

Embodiment
Embodiment:
As shown in Figure 1, a kind of flexible connecting device for underground petroleum pipeline of the present utility model, mainly comprise pipeline A1 and pipeline B7, flexible steel in flat section tubing 4, seal ring 3, sealing gasket 5 and tightening nut 6, pipeline A1 and pipeline B7 is tightly connected by seal ring 3, flexible steel in flat section tubing 4, and is fixed by tightening nut 6 and sealing gasket 5.The jointing of pipeline A1 and pipeline B7 is provided with protruding end, protruding end face has 20 circular holes.Seal ring 3 is " O " shape structure, its external diameter is identical with pipeline protruding end, seal ring 3 end has 20 circular holes, its diameter is identical with the Circularhole diameter on protruding end face, NBR nitrile rubber selected by seal ring 3, flexible steel in flat section tubing 4 and the sealing of pipeline A1, pipeline B7 can be realized when the seal ring 3 of 20 circular holes works, prevent tube fluid from leaking.Sealing gasket 5 and tightening nut 6 quantity are respectively 20, sealing gasket 5 is with " O " shape structure, material is NBR nitrile butadiene rubber, and sealing gasket 5 realizes the fixing seal of fixed bolt 2 and pipeline A1, pipeline B7, realizes the secondary seal of tube fluid and prevents managing outer foreign matter and enter in pipe.
