Abstract
The utility model relates to a self-sealing pipe connector for air pipeline connection, and is particularly suitable for the pipeline connection of railway rolling stock. The self-sealing pipe connector is composed of a concave-head connector head, a sealing ring, a raised-head connector body and a locking nut, wherein the sealing ring is arranged in an inner hole in the concave-head connector during connection, the concave-head connector body and the raised-head connector body are connected, and an inner thread of the locking nut is screwed tightly with the concave-head connector body through a special tool. Outer ends of the concave-head connector body and the raised-head connector body are respectively welded on two pipeline end sockets required to be connected, and sealing function is formed as the locking nut drives the raised-head connector body to press the sealing ring. The thread of the locking nut adopts anti-loosening thread, is good in anti-loosening property and suitable for the sealing under vibration working conditions. The connector can automatically find the center after being connected and is beneficial to preventing the sealing ring from being damaged during installation. The self-sealing pipe connector can only be disassembled and assembled by the aid of the special tool, thereby having anti-theft property in wild environment.
Description
Technical field
The utility model relates to the self-sealing tube joint that a kind of air pipe line connects, and especially is suitable for the connection of railway vehicle braking with pipeline.
Background technique
At present, the braking line of railway vehicle generally adopts flanged joint or ready-packaged joint to connect.Because; The operation area span of railway vehicle is big; Range of temperature is big, reasons such as circumstance complication, and the structural type of flanged joint and ready-packaged joint and mounting type are difficult to guarantee the seal request of railway vehicle braking line in running; Particularly under the low temperature environment, sewing of joint is comparatively outstanding.
Summary of the invention
The purpose of the utility model is in order to solve the deficiency that above-mentioned existing technology exists; Provide a kind of simple, selfsealings effect better, can adapt to the braking self-sealing tube joint that the railway vehicle of various variation of ambient temperature is used, the different specifications model can be provided according to the external diameter of pipeline.
For realizing above-mentioned purpose; A kind of self-sealing tube joint that the utility model provided; It is characterized in that described this self-sealing tube joint is made up of recessed fittings body, seal ring, locking nut and plush copper fittings body; This recessed fittings body left end endoporus welds with the left pipeline termination that needs to be connected; In the right-hand member endoporus seal ring is set, the plush copper fittings body is packed in the locking nut and is extended the end face of pushing down seal ring in the endoporus of recessed fittings body, and the locking nut on the plush copper fittings body is threaded with recessed fittings body; Promptly compress seal ring through locking nut drive plush copper fittings body and be connected and sealed, plush copper fittings body right-hand member endoporus welds with the right pipeline termination that needs be connected.
Described seal ring is formed by oil resistant arctic rubber and metal frame sulfuration, and the upper and lower lip symmetry of sealing circle is pressed on lip opening-like attitude in back in recessed the fittings body through the plush copper fittings body.Four semicircle elongated slots are arranged on the described locking nut outer surface.
The utility model key points in design is: one, aperture one headgear of recessed fittings body goes into to need a pipeline termination of connection, and is integrally welded.The maximum outside diameter surface of recessed joint is threaded, is connected with locking nut during assembling.Two, the plush copper fittings body is packed in the locking nut, and macropore one headgear of plush copper fittings body is gone into to need another pipeline termination of connecting, and is integrally welded.Three, the plush copper of plush copper fittings body stretches into recessed fittings body endoporus and play the guiding role when joint connects.Four, the outer astragal metal frame structure of seal ring, upper and lower lip is symmetrically distributed.
The working principle of the utility model: the two pipeline terminations that need to connect are welded with recessed fittings body and plush copper fittings body respectively; When pipeline connects seal ring put into the macropore bottom of recessed fittings body, recessed fittings body docked with the plush copper fittings body, and the internal thread of locking nut and the outside thread of recessed fittings body are screwed to specified value through special tool.In the rundown process of locking nut, the endoporus that the plush copper of plush copper fittings body stretches into recessed fittings body play the guiding role, and has guaranteed that the center of two pipelines overlaps, and can effectively prevent locking nut damage to seal ring in rundown process; The lip that pipeline connects the back seal ring still is certain open state.After the pipeline pressurising, atmospheric pressure will make two lips of seal ring produce a pressure that is adjacent to recessed fittings body and plush copper fittings body sealing surface respectively, improve the sealing function of seal ring.
Compare with ready-packaged joint with the flanged joint that existing brake tube for railway vehicle road is used, this is suitable for the novel following advantage that has:
One of which, this joint is when connecting, and the plush copper of plush copper fittings body stretches into recessed fittings body endoporus and play the guiding role, and can prevent effectively that damaging seal ring because of installation process influences sealing effect;
Its two, the lip that pipeline connects the back seal ring still is certain open state, after the pipeline pressurising, atmospheric pressure will make two lips of seal ring produce a pressure that is adjacent to recessed fittings body and plush copper fittings body sealing surface respectively, improve the sealing function of seal ring.
