2. the impact of the hydraulic oil on the high-pressure oil pipe is overlarge, and the service life of the high-pressure oil pipe is shortened.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problem that hydraulic oil impact is large due to the fact that a conventional straight-line-shaped hydraulic pipe joint is limited by installation space, and provides an angle joint type quick hydraulic pipe joint which forms a right-angled bent hydraulic oil duct, reduces installation height and hydraulic impact, and achieves the effects of being suitable for installation in narrow space and prolonging the service life of a high-pressure oil pipe.
In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides a quick hydraulic pressure coupling of angle joint formula, its includes that the angle connects elbow joint, special first screw and coupling nut, the side that the angle connects elbow joint is equipped with the side interface, is equipped with down the hole below, and inside is equipped with the cross hole, the side export of this cross hole with the side interface communicates with each other, the downside export of this cross hole with the down hole communicates with each other, down hole, cross hole and side interface link to each other in proper order form the hydraulic pressure oil duct of right angle bending, special first screw is the pipe fitting of step appearance, and inside is equipped with the centre bore that link up, coupling nut pass through threaded connection in the lower part of angle joint elbow joint and will special first screw compresses tightly in the lower hole of this angle joint elbow joint.
Furthermore, an O-shaped sealing ring and a check ring for sealing hydraulic oil are arranged between the periphery of the special head screw and the inner wall of the lower connecting hole of the angle-joint elbow joint.
Furthermore, the periphery of the special head screw is provided with a large boss and a small boss, the lower side face of the large boss is tightly propped by the connecting nut, and the periphery of the small boss and the inner wall of the lower connecting hole of the angle joint elbow joint form clearance fit.
Furthermore, the outer wall of the lower connecting hole of the angle-joint elbow connector is provided with an external thread, and the inner wall of the connecting nut is provided with an internal thread matched with the external thread.
The utility model has the following beneficial technical effects:
1) the angle joint type quick hydraulic pipe joint effectively reduces the installation height and is beneficial to the use of a hydraulic stretcher in a narrow space;
2) the utility model reduces the impact force of the hydraulic oil on the hydraulic oil pipe and is beneficial to prolonging the service life of the high-pressure oil pipe.
In a word, the hydraulic pipe joint realizes that the installation of the hydraulic pipe joint is converted from the straight-line-shaped connection into the right-angle-shaped connection, overcomes the difficulty that the straight-line-shaped hydraulic pipe joint cannot be installed due to the limitation of narrow space, simultaneously solves the problem that the straight-line-shaped hydraulic pipe joint generates great impact force on a high-pressure oil pipe when being connected with an upward hydraulic stretcher, greatly shortens the service life of the high-pressure oil pipe, and has the advantages of simple structure, convenient operation and good effect.
