Abstract

The invention discloses a right-angle pipe joint of a hydraulic pipeline, which comprises a right-angle joint body; a pipeline connector is arranged at an output end of the right-angle joint body; the pipeline connector comprises a joint body, a pipeline, a sealing ring and a nut; the joint body comprises a connecting part provided with external threads, and a stepped hole with with a small front and a large rear is arranged on the connecting part; the rear end of the stepped hole is a conical hole; an annular anti-falling protrusion is formed at a pipe end of the pipeline through a cold forming process; the sealing ring matched with the conical hole is arranged on the pipeline in front of the annular anti-falling protrusion; and the pipeline behind the annular anti-falling protrusion is sleeved with the nut in threaded connection with the connecting part; and the right-angle joint body comprises a cavity body, a buffer plate, a plurality of elastic supporting bodies and a plurality of flow dividing column bodies. Compared with the prior art, the impact resistance can be improved, the requirements for the precision and hardness of a pipe are lowered, the installation torque is reduced, and parts are reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of pipe joints, in particular to the technical field of hydraulic pipeline right-angle pipe joints. 【Background technique】 [0002] The function of the right-angle pipe joint is to change the direction of the pipeline, and then change the flow direction of the medium circulating in the pipeline. In the prior art, after a long period of use, the right-angle pipe joint will have cracks or even rupture due to excessive pressure; therefore, it is particularly necessary to modify the inside of the right-angle pipe joint to improve the impact resistance; because The connection between the right-angle pipe joint and the pipe generally adopts a ferrule-type connection, which has the advantages of good connection and sealing, convenient and quick installation and operation, etc. Its application range and number of uses are constantly increasing, and higher requirements are also put forward. For example, the origin...
