Abstract
The utility model discloses a petroleum pipeline coupling, including coupling area under control and internal thread the middle part in coupling area under control is equipped with the arch to axial direction of the pipe, respectively is equipped with a sealing washer in protruding both sides. Be equipped with inward arch at the coupling center, be equipped with the sealing washer in protruding both sides, after petroleum pipeline passes through the internal thread and gets into the coupling, can crowd the compacting seal, make the sealing washer fill up the leakproofness of the space between arch, internal thread and the petroleum pipeline, reinforcing pipeline kneck.
Description
Technical field
The utility model is related to petroleum pipeline technical field, especially a kind of petroleum pipeline box cupling.
Background technology
Oil well is the eyelet bored for exploitation oil, is the passage that oil is risen to well head by shaft bottom.General oil well is being bored
Up to after oil reservoir, under enter production string, and the annular space injection oil-well cement between sleeve pipe and the borehole wall, to safeguard the borehole wall and closing
Oil, gas and water layer, after penetrate out oil reservoir by the requirement perforating gun of oil field development, form passage, under enter oil pipe, lure stream with suitable
Method, well head is risen to by oil by oil well shaft bottom.The general box cupling of oil well petroleum pipeline is connected, and box cupling is used with petroleum pipeline
Threaded connection, because box cupling and petroleum pipeline are not one, it may occur that oil leakage phenomenon.
Utility model content
The purpose of this utility model is to solve the above problems, there is provided a kind of petroleum pipeline box cupling.
What the purpose of this utility model was implemented by the following technical programs：
A kind of petroleum pipeline box cupling, including box cupling area under control and internal thread, the middle part in the box cupling area under control be provided with to
The projection of tube axis direction, a sealing ring is respectively provided with raised both sides.
Further, the sealing ring is fluorosioloxane rubber O-ring.
Further, the internal thread is arranged between box cupling one end and projection.
The beneficial effects of the utility model are：
The petroleum pipeline box cupling that the utility model is provided, inside projection is provided with box cupling center, is provided with raised both sides
Sealing ring, after petroleum pipeline enters box cupling by internal thread, can crush seal circle, make sealing ring fill up raised, internal thread with
Space between petroleum pipeline, the sealing at enhancing pipe joint.
