Abstract
The invention discloses a tightly mounted oil pipe coupling, and solves the problem that when existing oil pipelines connected to two ends cannot effectively and freely rotate, coupling mounting cannot be properly realized, and consequently, operation is greatly limited. The oil pipe coupling comprises a coupling pipe body (1), and internal threads (3) formed on the inner wall of the coupling pipe body (1) and matched with external threads on the connector of an oil pipeline, and is characterized in that clamping devices (3) are arranged at the two ends of the coupling pipe body (1); each clamping device (3) comprises an annular fastener (31), and a bucket (32) sleeving the annular fastener (31) and being in threaded connection with the annular fastener (31). The oil pipe coupling has the advantages that the oil pipe coupling is more convenient to mount, and connection between the coupling and the oil pipeline is stabler.
Description
Technical field
The present invention relates to a kind of box cupling, be specifically related to a kind of tubing coupling fastening installation.
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 to be usually and be first wound around glass fiber or the rope made of hemp at the external screw thread 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 practice have shown that to adopt the form that glass fiber or the rope made of hemp are wound around to carry out oil pipe and tubing coupling sealing, and sealing effectiveness is bad, easily occurs crude oil Seepage in use procedure.
In order to solve the problems referred to above, the patent No. is a kind of self sealss tubing coupling disclosed in the file of CN201320152391.X, there is tubulose box cupling body, the two ends of box cupling body have connection female thread, the box cupling inner body wall connected between female thread at described box cupling body two ends is compounded with rubber seal ring, 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. Adopt the self sealss tubing coupling of said structure, owing to the box cupling inner body wall connected between female thread at described box cupling body two ends being compounded with rubber seal ring, 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 said structure needs the petroleum pipeline having at least one end in the petroleum pipeline that two ends connect can be freely rotatable, for two ends petroleum pipeline all can not effectively 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 box cupling well, cause that operation has great limitation;Purpose is in that to provide a kind of tubing coupling fastening installation solving the problems referred to above.
The present invention is achieved through the following technical solutions:
A kind of tubing coupling fastening installation, including box cupling body, the female thread being arranged on box cupling inboard wall of tube body and matching with petroleum pipeline seam external screw thread, described box cupling 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.
The process that implements of the present invention is:
Box cupling 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 box cupling body is reversely rotated, until stopping the rotation when being respectively positioned in coupling pipe body in two petroleum pipeline road junctions, finally rotate this latch closure, make annular fastener be tightly fixed on petroleum pipeline.
By above-mentioned setting, without rotating petroleum pipeline, can effectively realize threadeding of petroleum pipeline and box cupling body, the installation of box cupling can be realized afterwards well. Which makes the installation connection easier, between box cupling and petroleum pipeline of box cupling more stable.
Further, described annular fastener is be arranged in parallel by two or more and is fixed on the anchorage bar of box cupling body end after circular array, the outer combination screw thread composition being arranged on all anchorage bars and being formed after combination; It is provided with match with outer combination screw thread interior inside described latch closure and is connected 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.
Preferably, described anchorage bar is provided with the pad that the direction thickness along fixing end is gradually reduced.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, the present invention without rotating petroleum pipeline, can effectively realize threadeding of petroleum pipeline and box cupling body, can realize the installation of box cupling afterwards well;
2, in the present invention, the installation of box cupling connection easier, between box cupling and petroleum pipeline is more stable;
3, present configuration is simple, cost performance is high, and effect is notable, is especially suitable for popularization and application.
