Abstract
The utility model discloses a pipe joint for the air brake pipeline connection of an automobile. The pipe joint comprises a joint body, wherein an annular sealing groove is formed in the surface of the end part of the joint body, external sealing threads and external connecting threads are respectively formed in the surface of the joint body at the two sides of the annular sealing groove, a sealing nut and a thread gasket are sequentially arranged on the external sealing threads, and an O-shaped sealing ring is nested in the annular sealing groove. The joint body is provided with the annular sealing groove, and the O-shaped sealing ring is compressed by the sealing nut through the thread gasket and is arranged in the annular sealing groove, so that the damage to the O-shaped sealing ring caused by the threads is avoided, the percent of pass of mounting is increased, and a brake system is guaranteed of long-term and stable work.
Description
Technical field
The utility model relates to a kind of braking line connecting tube joint.
Background technique
Pipe joint is to be connected in automobile air brake system, is mainly to be connected between high-pressure air pipe and valve element.Also be applied at present the control gear of clutch booster and high low speed, mainly comprise fittings body, hexagon nut, screw thread packing ring and " O " RunddichtringO.For guaranteeing the braking system normal operation, each braking member, pipe joint, tracheae etc. can not have gas leak phenomenon.
Original pipe joint is in installation process, and " O " RunddichtringO is easily damaged by screw thread, causes and breaks, and can produce gas leak phenomenon, greatly reduces the once mounting up-to-standard rate, and can not reuse.
Summary of the invention
Technical problem to be solved in the utility model is to provide the automobile air brake pipeline connection pipe joint of a kind of long service life, good sealing effect.
For solving the problems of the technologies described above, the technical solution of the utility model is: the automobile air brake pipeline connects uses pipe joint, comprise joint body, described joint body end surface is provided with closure gasket groove, the joint body surface of described closure gasket groove both sides is respectively equipped with the sealing outside thread and is connected outside thread, be provided with successively sealing nut and screw thread packing ring on described sealing outside thread, be set with " O " RunddichtringO in described closure gasket groove.
Owing to having adopted technique scheme, the automobile air brake pipeline connects uses pipe joint, comprise joint body, described joint body end surface is provided with closure gasket groove, the joint body surface of described closure gasket groove both sides is respectively equipped with the sealing outside thread and is connected outside thread, be provided with successively sealing nut and screw thread packing ring on described sealing outside thread, be set with " O " RunddichtringO in described closure gasket groove; On described joint body, closure gasket groove is arranged, sealing nut compresses " O " RunddichtringO by the screw thread packing ring, and " O " RunddichtringO is located in closure gasket groove, has avoided " O " RunddichtringO to be damaged by screw thread, improve the installation qualification rate, guaranteed the long-term stable operation of braking system.
Description of drawings
Accompanying drawing is the utility model embodiment's structural representation;
In figure: the 1-joint body; The 2-closure gasket groove; 3-seals outside thread; 4-connects outside thread; The 5-sealing nut; 6-screw thread packing ring; 7-" O " RunddichtringO.
Embodiment
As shown in drawings, the automobile air brake pipeline connects uses pipe joint, comprise joint body 1, described joint body 1 end surface is provided with closure gasket groove 2, the joint body surface of described closure gasket groove 2 both sides is respectively equipped with sealing outside thread 3 and is connected outside thread 4, be provided with successively sealing nut 5 and screw thread packing ring 6 on described sealing outside thread 3, be set with " O " RunddichtringO 7 in described closure gasket groove 2.
Closure gasket groove 2 is arranged on described joint body, sealing nut 5 compresses " O " RunddichtringO 7 by screw thread packing ring 6, and " O " RunddichtringO 7 is located in closure gasket groove 2, has avoided " O " RunddichtringO 7 to be damaged by screw thread, improve the installation qualification rate, guaranteed the long-term stable operation of braking system.
