Description
Technical field
The present invention relates to petroleum machineries, and in particular to a kind of oil well suction channel.
Background technology
In existing technology oil well suction channel be more piece pipeline is combined into it is one whole, in world's course of work due to
Vibration or the effect of external force can make pipeline loosen, to the tightness connected there is a problem of it is certain, it is therefore desirable to carry
Such technical problem is solved for a kind of technical solution.
Invention content
The present invention provides a kind of oil well suction channel, the purpose for designing and developing the present apparatus is so that the company between tube coupling
It connects more firm.
Present invention employs following technical solutions：A kind of oil well suction channel, the oil well suction channel include tube body 1,
The lower end of the tube body 1 is equipped with the first screwed ring 2, the second screwed ring 3, and first screwed ring 2 is same with second screwed ring 3
The heart, the upper end of the tube body 1 are equipped with the first thread groove 4, the second thread groove 5, first screwed ring 2, the second screwed ring 3 it is interior
Wall is equipped with internal thread, first screwed ring 2, the second screwed ring 3 outer wall be equipped with external screw thread, first screwed ring 2 with
First thread groove, 4 internal and external threads screw, and second screwed ring 3 is screwed with 5 internal and external threads of the second thread groove, described
First thread groove 4, the second thread groove 5 are annular groove, first thread groove 4, the second thread groove 5 bottom be equipped with rubber
Circle 6.
Beneficial effects of the present invention are as follows：First screwed ring 2 is screwed with 4 internal and external threads of the first thread groove, institute
It states the second screwed ring 3 to screw with 5 internal and external threads of the second thread groove, the present apparatus is using four pairs of internal and external threads while the company of screwing
It connects so that connection is more firm, and increases sealing performance equipped with rubber ring 6 in bottom.The present apparatus makes between tube coupling
Connection is more firm.
