Abstract
The invention discloses a flexible petroleum pipe coupling. The flexible petroleum pipe coupling comprises an outer flexible ferrule and an inner flexible ferrule located in the outer flexible ferrule. The outer flexible ferrule and the inner flexible ferrule are both circular tubes with quarter turns in the middles. Each quarter turn has a transition fillet. The two ends of the outer flexible ferrule are provided with a first ferrule head and a second ferrule head in an inserted mode correspondingly. The central axis of the first ferrule head is perpendicular to the central axis of the second ferrule head. The first ferrule head and the second ferrule head are both of a circular tube structure. The outer ring of the first ferrule head and the outer ring of the second ferrule head are each provided with a section of sawtoothed grooves. The two ends of the inner flexible ferrule are mounted in the first ferrule head and the second ferrule head in an inserted mode correspondingly. A spring is sleeved between the inner flexible ferrule and the outer flexible ferrule. The two sides of the spring are clamped in the sawtoothed grooves of the first ferrule head and the sawtoothed grooves of the second ferrule head correspondingly. The flexible petroleum pipe coupling has flexibility, applicable to the quarter turns and capable of ensuring smoothness of an oil way.
Description
Technical field
The present invention relates to petroleum pipeline field and in particular to a kind of flexibility petroleum pipe coupling.
Background technology
Petroleum pipe coupling is one kind of oilfield wellbore tools, is mainly used in the connection of oil pipe, and application is quite varied, but existing
There is the petroleum pipe coupling structure in technology single, and be rigid member it is impossible to meet use requirement, especially for having right angle
The position turned, existing petroleum pipe coupling cannot be applied, if not adopting safeguard procedures, oil pipe easily produces in right-angled bend position
Raw bending is it is impossible to ensure the unobstructed of oil circuit.
Content of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of flexibility petroleum pipe coupling, and this petroleum pipe coupling has soft
Property, can be suitable for it is ensured that oil circuit is unobstructed in right angle turn.
The purpose of the present invention to implement by the following technical programs：
A kind of flexibility petroleum pipe coupling, cuff in the flexibility including the outer cuff of flexibility and within positioned at flexible outer cuff, described soft
Property outer cuff and flexibility in cuff be the pipe that middle part has right-angled bend, in right angle turn, there is knuckle, described
Grafting is provided with the first hoop head and the second hoop head, the axis of described first hoop head and the second hoop head respectively at the two ends of flexible outer cuff
Line is mutually perpendicular to, and the first hoop head and the second hoop head are circular tube structure, offer one in the outer ring of the first hoop head and the second hoop head
Section serrated slot, in described flexibility, grafting is arranged in the first hoop head and the second hoop head respectively at the two ends of cuff, described flexible in hoop
It is arranged with spring, the both sides correspondence of described spring is connected to described first hoop head and the second hoop between set and the outer cuff of described flexibility
In the serrated slot of head.
Further, the outer cuff of described flexibility and cuff in described flexibility are made by rubber, described first hoop head and the
Two hoop heads are made of stainless steel.
Further, the circumference of the outer cuff of described flexibility, the first hoop head and the second hoop head uniformly offers at least two
Trip bolt hole.
The present invention provides a kind of flexibility petroleum pipe coupling, this petroleum pipe coupling include the outer cuff of flexibility, cuff in flexibility, the
One hoop head, the second hoop head and the spring between cuff in flexible outer cuff and flexibility, have flexibility, can adjust, straight
Angle turning can be suitable for it is ensured that oil circuit is unobstructed.
Brief description
Below according to drawings and Examples, the present invention is described in further detail.
Fig. 1 is a kind of structural representation of present invention flexibility petroleum pipe coupling.
In figure：The flexible outer cuff of 1-；Cuff in 2- flexibility；3- knuckle；4- first binds round head；5- second binds round head；6- saws
Teeth groove；7- spring；8- trip bolt hole.
Specific embodiment
As shown in figure 1, a kind of flexibility petroleum pipe coupling described in the embodiment of the present invention, include flexible outer cuff 1 and be located at
Cuff 2 in flexibility within flexible outer cuff 1, in flexible outer cuff 1 and flexibility, cuff 2 is the circle that middle part has right-angled bend
Pipe, has knuckle 3 in right angle turn, grafting is provided with the first hoop 4 and the second hoop respectively at the two ends of flexible outer cuff 1
5, the first hoop 4 is mutually perpendicular to the axis of the second hoop 5, and the first hoop 4 and second binds round 5 and is circular tube structure,
The outer ring of the first hoop 4 and the second hoop 5 offers one section of serrated slot 6, and in flexibility, grafting is arranged on the respectively at the two ends of cuff 2
In one hoop 4 and the second hoop 5, it is arranged with spring 7 in flexibility between cuff 2 and flexible outer cuff 1, the both sides of spring 7 correspond to
It is connected in the first hoop 4 and the serrated slot 6 of the second hoop 5.
The present invention when using, bind round in heads and the second hoop head and in flexibility respectively to need two oil pipes docking by grafting first
Cuff is docked, and because in the outer cuff of flexibility and flexibility, cuff is respectively provided with flexibility, the spring simultaneously arranging has recovery deformation and guarantor
The effect of shield, so that pipe box cupling can adjust, can be suitable for it is ensured that oil circuit is unobstructed in right angle turn.
One kind preferred embodiment, flexible outer cuff 1 with flexible in cuff 2 made by rubber, first binds round 4 and the
Two hoops 5 are made of stainless steel, and on the basis of ensureing use requirement, reduces cost is it is easy to purchasing and processing.
It is more highly preferred to, the circumference of flexible outer cuff 1, first hoop 2 and the second hoop 3 uniformly offers four fastenings
Screw hole 8, oil pipe is easily installed trip bolt after being plugged on the first hoop head and the second hoop head respectively, and oil pipe is fastened.
The present invention provides a kind of flexibility petroleum pipe coupling, and this petroleum pipe coupling has flexibility, can fit in right angle turn
With it is ensured that oil circuit unobstructed it is easy to promote the use of.
Finally it should be noted that：The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention,
For a person skilled in the art, it still can be adjusted to the technical scheme described in foregoing embodiments, or
Person carries out equivalent to wherein some technical characteristics, all any modifications within the spirit and principles in the present invention, made, etc.
With replacing, improving etc., should be included within the scope of the present invention.
