Abstract
The utility model provides a leak-proof high-pressure oil pump pipeline, which comprises an oil pipe and a joint, wherein the joint is a 45-degree elbow, two ends inside the joint are respectively provided with an annular limiting boss, a turning part inside the joint is provided with a ladder-shaped structure, and the oil pipe stretches into two ends of the joint and is limited by the limiting bosses to be welded and fixed with the joint; the joint is of an integrally formed structure. The utility model has the advantages of simple overall structure, the echelonment structure that connects inside turning setting has cushioned the impact force of high-pressure oil, makes the high-pressure oil form cascaded advancing, avoids only impacting a bit position after the high-pressure oil input in the past, and the leak protection is effectual, and the echelonment structure has thickened the impact position, has prolonged the life who connects. Meanwhile, the oil pipe extends into the joint and is welded and fixed after being matched with the joint, the connection is firm, the sealing performance is good, the influence of the fluid state inside the oil pipe is avoided, the high-pressure oil can be conveyed, and the oil leakage condition is avoided.
Description
Technical Field
The utility model belongs to the technical field of hydraulic system equipment, especially, relate to a leak protection high-pressure oil pump pipeline.
Background
In a hydraulic system, a 45-degree oil pipe joint is needed between steering oil pipes, in order to prevent leakage of the oil pipe joint, a sealing ring or a sealing gasket is usually added between the oil pipe joint and the oil pipe to prevent leakage, but when the sealing ring or the sealing gasket is used, the sealing ring or the sealing gasket is greatly influenced by oil pressure and oil temperature, and when the oil pressure and the oil temperature are high, abrasion easily occurs, so that leakage is caused. In addition, when high-pressure oil is conveyed, the joint with the structure is subjected to large impact force, and leakage is more likely to occur.
Disclosure of Invention
The to-be-solved problem of the utility model is to provide a simple structure, sealed effectual, long service life's leak protection high-pressure oil pump pipeline.
In order to solve the technical problem, the utility model discloses a technical scheme is: the utility model provides a leak protection high-pressure oil pump pipeline, includes oil pipe and joint, connect and be 45 elbows, should connect inside both ends and all be provided with cyclic annular spacing boss, should connect inside turn and be provided with the echelonment structure, oil pipe stretches into and connects both ends and pass through spacing boss spacing, with connect welded fastening.
The joint is of an integrally formed structure.
Since the technical scheme is used, the utility model has the advantages that overall structure is simple, the echelonment structure that connects the inside turning setting has cushioned the impact force of high-pressure oil, makes high-pressure oil form cascaded the gos forward, only strikes a bit position after avoiding high-pressure oil input in the past, and the leak protection is effectual, and the echelonment structure has thickened the impact position, has prolonged the life who connects. Simultaneously, connect inside both ends and be provided with cyclic annular spacing boss, oil pipe stretches into and connects both ends spacing through spacing boss, with connect welded fastening, connect as an organic whole shaping structure, above design makes oil pipe stretch into to connect, with connect welded fastening again after the cooperation, firm in connection, the leakproofness is good, and can not receive the influence of the inside fluid state, can realize the transport of high pressure oil, avoids the emergence of the oil leak condition.
The utility model has the advantages that: has the advantages of simple structure, good sealing effect, long service life and leakage prevention.

Detailed Description
As shown in fig. 1 and 2, the leakage-proof high-pressure oil pump pipeline of the present invention comprises an oil pipe 1 and a joint 2, wherein the joint 2 is a 45 ° elbow, both ends inside the joint 2 are provided with annular limiting bosses 3, a turn inside the joint 2 is provided with a stepped structure 4, the oil pipe 1 extends into both ends of the joint 2 and is limited by the limiting bosses 3, and is welded and fixed with the joint 2; the joint 2 is of an integrally formed structure.
The utility model has the advantages of simple overall structure, the echelonment structure 4 that connects 2 inside turnings to set up has cushioned the impact force of high-pressure oil, makes the high-pressure oil form cascaded advancing, only strikes a bit position after avoiding high-pressure oil input in the past, and the leak protection is effectual, and echelonment structure 4 has thickened the impact position, has prolonged the life who connects 2. Simultaneously, connect 2 inside both ends and be provided with cyclic annular spacing boss 3, oil pipe 1 stretches into and connects both ends and pass through spacing boss 3 spacing, with connecting 2 welded fastening, connect 2 and be the integrated into one piece structure, above design makes oil pipe 1 stretch into and connects 2, with connect 2 after the cooperation welded fastening again, firm in connection, the leakproofness is good, and can not receive the influence of the inside fluid state, can realize the transport of high pressure oil, avoids the emergence of the oil leak condition.
The embodiments of the present invention have been described in detail, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should be covered by the present patent.
