The utility model discloses a coupling body (1), set up on coupling body (1) inner wall and with petroleum pipeline kneck external screw thread assorted internal thread (2), a serial communication port, coupling body (1) both ends all are provided with fastener (3), fastener (3) including annular fastener (31), cup joint on annular fastener (31) just latch closure (32) with annular fastener (31) threaded connection. The utility model has the advantages of the installation is simple and convenient more, between coupling and the petroleum pipeline be connected more stable.
Description
Technical field
This utility model relates to a kind of box cupling, is specifically related to fastening type petroleum pipeline box cupling.
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 this utility model to connect oil pipeline, oil pipe docks closely with tubing coupling of the present utility model, 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.
Utility model content
Technical problem to be solved in the utility model 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 operation to have great limitation；Purpose is to provide a kind of fastening type petroleum pipeline box cupling solving the problems referred to above.
This utility model is achieved through the following technical solutions:
Fastening type petroleum pipeline box cupling, 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 utility model 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, can effectively realize threadeding of petroleum pipeline and box cupling body without rotating petroleum pipeline, 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 formed after being arranged on all anchorage bars and combining；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.
This utility model compared with prior art, has such advantages as and beneficial effect:
1, this utility model can effectively realize threadeding of petroleum pipeline and box cupling body without rotating petroleum pipeline, can realize the installation of box cupling afterwards well；
2, in this utility model, the installation of box cupling connection easier, between box cupling and petroleum pipeline is more stable；
3, this utility model simple in construction, cost performance height, effect is notable, is especially suitable for popularization and application.
