Abstract

The utility model discloses a pipeline connector for a seal connection between two pressure pipelines, including a socket pipe whose two ends can be sheathed simultaneously to two socket pipes outside two pipes which are to be connected. The two ports of the socket pipe are bell mouths which gradually contract from outside to inside and the external cylinder surface of the two ends of the socket pipe are provided with an external thread respectively. Two pinch nuts which may be sheathed to the pipe to be connected are respectively engaged with the external threads in two ends of the socket pipe. The inside of the pinch nut is provided with a bulge extending to the inside of the socket pipe in an axial direction. A seal ring which can be sheathed to the pipe to be connected is arranged between the bulge and the bell mouth. When working, a sealing face is formed between the seal ring and the socket pipe as well as between the seal ring simultaneously and the external cylinder of the pipe that is to be connected so as to realize seal connection. The utility model does not require high space between pipelines. A good seal can be realized no matter how much the space is. Besides, A certain distortion and vibration can be adapted via self elasticity of the seal ring so as to make the utility model more reliably to be used. The utility model is suitable to be applied to the seal connection of a pressure pipe.

Description

Pipe jointer

Technical field

The utility model relates to a kind of device that two pipelines are linked together, the particularly device that two pressure pipings are connected and sealed.

Background technique

In the prior art, two seals for pipe joints are connected the main technological scheme that adopts welding to be connected with flange, these two kinds of technological schemes are all had relatively high expectations to the gap between two pipelines to be connected, excessive gap then is difficult for welding or is difficult to sealing, too small gap can make and be difficult to put into gasket seal between the flange, and welding manner can make the dismounting difficulty; Under the working environment of long-term vibration and distortion, welding part and flange root rupture easily.

The model utility content

The purpose of this utility model is to provide a kind of technological scheme of pipe jointer, makes energy excellent sealing between two pipelines, and the gap between the pipeline is required to reduce, and can adapt to certain distortion and vibration.

The purpose of this utility model is achieved in that pipe jointer, it is characterized in that comprising that two ends can be sleeved on the outer socketed pipe of two pipelines to be connected simultaneously, socketed pipe two ends oral area is the horn mouth that shrinks gradually from outside to inside, socketed pipe two ends outer round surface is respectively equipped with outside thread, two locking nuts that can be nested with on pipeline to be connected are meshed with the outside thread at socketed pipe two ends respectively, the locking nut inboard is provided with the projection of axially extending to socketed pipe inside, is provided with the seal ring that can be sleeved on the pipeline to be connected between described projection and the horn mouth.

During the utility model work, earlier locking nut is nested with respectively on two pipelines to be connected, suit seal ring on two pipelines to be connected then, two ends and pipeline to be connected with socketed pipe socket-connects again, then seal ring is pushed in the horn mouth at socketed pipe two ends, then locking nut is connected with socketed pipe and locks, locking nut is pushed seal ring, makes seal ring form sealing surface simultaneously and between socketed pipe and the pipeline cylindrical to be connected.Realization is tightly connected; The utility model is less demanding to the gap between the pipeline, and no matter gap length all can be realized excellent sealing, in addition, elasticity by seal ring self can adapt to certain distortion and vibration, and its use is more reliable, is fit to be used in being tightly connected of pressure piping.

The utility model can be connected by the pipeline that two diameters are identical, and corresponding socketed pipe two ends internal diameter equates.As adopt the unequal socketed pipe of two ends internal diameter, then the unequal pipeline of two external diameters can be connected.

The section of described seal ring can be rounded; Also can be at right angles trapezoidal, and the hypotenuse of right-angled trapezium matches with horn mouth; Above-mentioned two technological schemes all can realize excellent sealing.
