Abstract
The invention relates to an oil pipe connection which comprises a connection body and a connecting pipe, wherein a nut is arranged between the connection body and the connecting pipe; one end of the connection body is provided with a conical groove; one end of the connecting pipe is provided with a conical surface; the conical surface is inserted in the conical groove; a first seal ring is arranged between the bottom surface of the conical groove and the end surface of the connecting pipe; and the conical surface is provided with a second seal ring. The oil pipe connection greatly enhances the sealability of the joint between the connecting pipe and the connection body, so that the joint between the connection body and the connecting pipe has favorable sealability and can not have the phenomenon of oil seeping, thereby greatly lowering the maintenance cost, and prolonging the service life of the high-pressure oil pipe connection.
Description
Technical field
The present invention relates to a kind of pipe joint, relate to specifically a kind of oil connection used in high-pressure oil pipe connects.
Background technique
At present, the connection of high-pressure oil pipe, by high-pressure oil pipe joint, connected, the high-pressure oil pipe joint now used comprises joint body, connecting tube and nut, joint body is cylindrical structural, be provided with the through hole passed through for high pressure oil on joint body, one end of joint body is provided with groove, one end of connecting tube is plugged in groove, nut sleeve is contained on connecting tube and with the connecting sleeve body and is threaded, connecting tube is plugged on the outer peripheral surface of the end in groove and is provided with seal ring, by seal ring, realizes the sealing between joint body and connecting tube.In use, seal ring easily damages this sealing means, and the oil impregnate phenomenon often appears in the joint of joint body and connecting tube, needs often high-pressure oil pipe joint to be keeped in repair, and has increased maintenance cost, has shortened the working life of high-pressure oil pipe joint.
Summary of the invention
The problem to be solved in the present invention is for above problem, and the joint good airproof performance of a kind of joint body and connecting tube, the oil connection that is not prone to the oil impregnate phenomenon, can reduces maintenance cost, increase the service life are provided.
For addressing the above problem, the technical solution adopted in the present invention is: a kind of oil connection, comprise joint body and connecting tube, be provided with nut between described joint body and connecting tube, one end of described joint body is provided with cone tank, and an end of described connecting tube is provided with conical surface, and described conical surface is plugged in cone tank, be provided with the first seal ring between the bottom surface of described cone tank and the end face of connecting tube, be provided with the second seal ring on described conical surface.
A kind of concrete optimized project, be provided with circular groove on the outer peripheral surface of described conical surface, and described the second seal ring is arranged in circular groove.
A kind of concrete optimized project, be respectively arranged with arc groove on the bottom surface of described cone tank and the end face of connecting tube.
A kind of concrete optimized project, be provided with through hole and spanner section on described joint body.
A kind of concrete optimized project, be provided with high-pressure oil passage on described connecting tube.
The present invention takes above technological scheme, have the following advantages: an end of joint body is provided with cone tank, one end of connecting tube is provided with conical surface, conical surface is plugged in cone tank, be provided with the first seal ring between the bottom surface of cone tank and the end face of connecting tube, be provided with the second seal ring on conical surface, greatly improved the sealing of connecting tube and joint body joint, the joint good airproof performance of joint body and connecting tube, be not prone to the oil impregnate phenomenon, greatly reduce maintenance cost, extended the working life of high-pressure oil pipe joint.
