The utility model has the advantages that: the right-angle air inlet joint component is additionally provided with the O-shaped sealing ring and the locking nut, the joint is coated with thread locking glue before installation, the thread locking glue and the O-shaped sealing ring are sealed in a double mode, and reliability is good.
Description
Technical Field
The utility model belongs to the technical field of the vehicle control device technique and specifically relates to a direction adjustable right angle air inlet joint subassembly is related to.
Background
The brake valve is a mechanism for braking the whole vehicle by utilizing the damping action of engine compression, and is an important control device in a service braking system. The right-angle air inlet joint on the market at present is roughly divided into two types: firstly, the connection thread of the right-angle air inlet joint and the air cylinder is a taper thread; the right-angle air inlet connector and the air cylinder are connected through threads which are straight threads, the right-angle air inlet connector can only meet the requirement that torque cannot be guaranteed in the direction of the air inlet connector of the air cylinder, looseness prevention of a joint can only be achieved by means of thread locking, the connector is easy to loosen in the application process, the exhaust brake valve fails, and the consequence is serious, and the air inlet connector and the air cylinder are defects in the prior art.
Disclosure of Invention
An object of the utility model is to overcome the shortcoming that exists among the prior art, provide can satisfy the direction adjustable and can also guarantee moment, locking flexible right angle air inlet joint subassembly, including the right angle joint body, its characterized in that: and a locking nut is arranged at one end of the right-angle joint body, which is connected with the internal thread at the air inlet of the exhaust brake butterfly valve, and an O-shaped sealing ring is arranged between the right-angle joint body and the locking nut.
The beneficial effects of the utility model reside in that: and a cylindrical groove is formed in the internal thread at one end of the locking nut, and the O-shaped sealing ring is arranged in the cylindrical groove.
The beneficial effects of the utility model still lie in: the depth dimension of the groove is lower than the diameter dimension of the O-shaped sealing ring.
The beneficial effects of the utility model still lie in: and a locking glue coating is arranged between the internal thread and the external thread which are matched with the internal thread at the position of the air inlet of the exhaust brake butterfly valve.
Therefore, the utility model discloses the advantage is: the right-angle air inlet joint component is additionally provided with the O-shaped sealing ring and the locking nut, the right-angle joint body is coated with the thread locking glue before installation, the thread locking glue and the O-shaped sealing ring are sealed in a double mode, and the reliability is good.
Drawings
Fig. 1 is a schematic structural diagram 1 of the present invention, and fig. 2 is a schematic installation diagram of a right-angle joint body.
Wherein 1, right angle joint body, 12, lock nut, 3, O type sealing washer, 2, exhaust braking butterfly valve.
Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
The utility model discloses a direction adjustable right angle air inlet joint subassembly, including right angle joint body 1, set up lock nut 12 with the female connection one end of 2 air inlet positions of exhaust brake butterfly valve at right angle joint body 1, O type sealing washer 3 sets up between right angle joint body 1 and lock nut 12.
In this embodiment, a cylindrical groove is provided at the internal thread of one end of the lock nut 12, and the O-ring 3 is inserted therein.
In this embodiment, the depth of the groove is smaller than the diameter of the O-ring 3.
In this embodiment, a locking glue coating is arranged between the internal and external threads matched with the internal thread at the air inlet of the exhaust brake butterfly valve 2 and the right-angle joint body 1.
The right-angle joint body 1 is coated with thread locking glue before installation, then the direction is adjusted according to the requirement of the whole vehicle pipeline, the locking nut 12 is tightly backed to reach the requirement of torque, and the O-shaped sealing ring 3 is tightly pressed. The thread locking glue and the locking nut 12 are double anti-loose in torque, and the O-shaped sealing ring 3 and the thread locking glue are double sealed. The reliability is good.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or replacements made by those skilled in the art within the scope of the present invention also belong to the protection scope of the present invention.
Claims (4)
