Abstract

The invention discloses a sealing joint. The sealing joint comprises a first joint body, a second joint body and a nut. A boss is arranged at one end of the first joint body, and a tapered first sealing face is arranged on the outer side of the boss; a first groove matched with the boss is formed in one end of the second joint body, a tapered second sealing face is arranged on the inner side of the first groove, and a tapered location face is arranged on the outer side of the first groove; and a second groove matched with the location face is formed in one end of an inner cavity of the nut, and the other end of the inner cavity of the nut is fixedly connected with the first joint body so as to enable the first sealing face and the second sealing face to be sealed. According to the sealing joint, the first joint body is directly matched with the second joint body through the tapered faces and the grooves, and compared with the prior art, the contact area is enlarged, and the sealing performance is improved; in addition, due to the fact that the location face is matched between the second joint body and the nut through the tapered second groove, the matching area of the nut and the second joint body is increased, the stress of the nut is more uniform, and location is more stable.

Description

technical field [0001] The invention relates to the technical field of sealing methods, in particular to a sealing joint. Background technique [0002] Generally, the braking system of heavy trucks adopts the pneumatic type. The gas output by the air compressor is transported to the air storage tank through the pipeline. When the vehicle brakes, the wheel actuator is driven to make the brakes installed on the wheels play a role, so as to achieve the purpose of decelerating the whole vehicle. . [0003] The air from the air compressor on the engine to the dryer on the frame needs a long section of transportation pipeline, which is usually transported by steel pipes, which can play a role in cooling down. The pipeline from the engine to the frame needs a section of brake soft Pipe transition, in order to achieve the purpose of vibration reduction, the connection between steel pipe and steel pipe, steel pipe and brake hose needs better sealing and reliability, it is required t...
