Description
Technical field
The present invention relates to a kind of connecting tube, be specifically related to spring stop piece adjustment type oil pipe connector.
Background technology
Pipeline conveying is carried of crude oil a kind of means of transportation most economical, rational.Pipeline conveying crude oil, connected mode between oil pipe is typically with tubing coupling and is attached, tubing coupling has tubulose box cupling body, the two ends of box cupling body have connection female thread, when using tubing coupling connected pipes, it is screwed in tubing coupling connection female thread having externally threaded oil pipe, forms oil continuative transport pipeline with this, it is achieved the continuative transport of oil.Seal connecting between above-mentioned tubing coupling of the prior art and oil pipe and be usually first at external screw thread winding glass fiber or the rope made of hemp of oil pipe, afterwards the oil pipe being tied with glass fiber or the rope made of hemp is screwed into tubing coupling, above-mentioned seal form there is the problem that one is that oil pipe and tubing coupling are installed relatively cumbersome, need to get out glass fiber or the rope made of hemp in advance, degree of tightness or thickness that additionally the rope made of hemp or glass fiber are wound around also can affect sealing effectiveness, wayward；Two is to practice have shown that the form using glass fiber or the rope made of hemp to be wound around carries out oil pipe and tubing coupling seals, and sealing effectiveness is bad, easily occurs crude oil Seepage during use.
In order to solve the problems referred to above, the file of Patent No. CN201320152391.X discloses a kind of self sealss tubing coupling, there is tubulose box cupling body, the two ends of box cupling body have connection female thread, it is compounded with rubber seal ring in the box cupling inner body wall connected between female thread at described box cupling body two ends, when oil pipe screw in box cupling body two ends connection female thread time, oil pipe end compress described rubber seal ring and and rubber seal ring between liquid-tight envelope.Use the self sealss tubing coupling of said structure, owing to being compounded with rubber seal ring in the box cupling inner body wall connected between female thread at described box cupling body two ends, therefore when the oil pipe using the present invention to connect oil pipeline, oil pipe docks closely with the tubing coupling of the present invention, oil pipe end compress described rubber seal ring and and rubber seal ring between liquid-tight envelope, do not have crude oil seepage.
But the petroleum pipeline that said structure needs at least one end in the petroleum pipeline that two ends connect can be freely rotatable, for two ends petroleum pipeline all can not the most freely rotatable in the case of, then cannot realize the installation of box cupling, operation has great limitation.
Summary of the invention
The technical problem to be solved is: existing two ends connect petroleum pipeline can not effective freely rotatable time, it is impossible to realize the installation of connecting tube well, cause operation to have great limitation；Purpose is to provide the spring stop piece adjustment type oil pipe connector solving the problems referred to above.
The present invention is achieved through the following technical solutions:
Spring stop piece adjustment type oil pipe connector, including connecting tube body, the female thread being arranged on connecting tube inboard wall of tube body and matching with petroleum pipeline seam external screw thread, described connecting tube body two ends are provided with clamp device；
Described clamp device includes annular fastener, the latch closure being socketed on annular fastener and threadeding with annular fastener；Said two clamp device is symmetrical arranged, and is provided with connecting rod between the latch closure on two clamp devices；
Described connecting rod one end is hinged on one of them latch closure, the other end is free end, another latch closure is then provided with the buckling groove for connecting rod clamping, is additionally provided with spring block piece in this buckling groove；
Described spring block piece includes the spring that one end is fixed on buckling groove cell wall, the perpendicular catch being fixed on the spring other end, and is vertically set on the strut rail sheet on perpendicular catch top；Being provided with shifting chute on the two side that described buckling groove is relative, the two ends of this strut rail sheet lay respectively in two shifting chutes.
The process that implements of the present invention is:
Connecting tube body is rotated on one of them petroleum pipeline, until exposing petroleum pipeline road junction, then another petroleum pipeline road junction is directed at this petroleum pipeline road junction, then this connecting tube body is reversely rotated, until stopping the rotation when being respectively positioned in connecting tube body in two petroleum pipeline road junctions, finally rotate this latch closure, make annular fastener be tightly fixed on petroleum pipeline, be then fixed in buckling groove by the free end of connecting rod.
By above-mentioned setting, can effectively realize threadeding of petroleum pipeline and connecting tube body without rotating petroleum pipeline, the installation of connecting tube can be realized afterwards well.Which makes the installation connection easier, between connecting tube and petroleum pipeline of connecting tube more stable.
And the direction screwed due to two latch closures is relative, thereby through the setting of connecting rod, can effectively prevent loosening of latch closure, reach the effect being preferably stably connected with.The effect of spring block piece can increase the applicable distance between two latch closures, makes operation easier.
Further, described annular fastener is be arranged in parallel by two or more and is fixed on the anchorage bar of connecting tube body end after circular array, the outer combination screw thread composition formed after being arranged on all anchorage bars and combining；It is provided with inside described latch closure and outer combination screw thread.
In order to be able to reach the fastening effect of optimum, described anchorage bar is string configuration, and the cross section of this anchorage bar is cambered surface trapezium structure.The pad that the direction thickness along fixing end is gradually reduced it is provided with on described anchorage bar.
As optimally set-up mode, described spring block piece includes the spring that one end is fixed on buckling groove cell wall, and the catch composition being fixed on the spring other end.
The card being hinged on latch closure to effectively prevent the upper surface of described buckling groove to be provided with.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, the present invention can effectively realize threadeding of petroleum pipeline and connecting tube body without rotating petroleum pipeline, can realize the installation of connecting tube afterwards well；
2, the present invention setting by connecting rod, can effectively prevent loosening of latch closure, reach the effect being preferably stably connected with.The effect of spring block piece can increase the applicable distance between two latch closures, and the installation connection easier, between connecting tube and petroleum pipeline making connecting tube is more stable；
3, present configuration is simple, cost performance is high, and effect is notable, is especially suitable for popularization and application.
