Description

Anti-drop type pipeline sealing connecting piece

Technical Field

The utility model relates to a pipe connection technical field especially relates to an anticreep type pipe seal connecting piece.

Background

In the pipelines for conveying liquid, the connection between the pipelines is usually in a flange connection or a form that an open locking ring holds the pipelines tightly. The flange connection has the defects of high processing difficulty and large installation space, and welding is required (and some materials cannot be welded at all), so that the flange connection mode cannot be used for pipeline connection in some occasions. When the pipe is sleeved in a manner that the open locking ring clasps the pipe, the locking nut is required to continuously generate pressing force on the locking ring to ensure the sealing connection of the pipe, once the locking nut is loosened, the pipe is loosened, and the liquid leakage phenomenon is caused; because the installation structure of the internal parts of the machine is compact, the space is limited when the locking nut is installed, so that the locking force of the locking nut is small, and the locking nut is easy to loosen after long-time work, so that the pipeline is loosened.

The patent with the application number of CN201320531064.5 discloses an anti-drop sealing connection structure for a pipeline, which comprises a pipe joint, a flow guide pipe, a lock nut, a seal ring and a retainer ring, wherein the end part of the flow guide pipe is inserted into the pipe joint, one end of the lock nut is in threaded connection with the outer wall of the pipe joint, the end part of the other end is provided with a radially inward blocking part, and the seal ring and the retainer ring are sleeved on the flow guide pipe and are pressed tightly on the end part of the pipe joint by the blocking part of the lock nut; the locking washer is sleeved on the flow guide pipe and located in the locking nut, the locking washer comprises an annular locking washer body, a plurality of internal teeth distributed along the circumferential direction are arranged on the locking washer body, the internal teeth are inclined towards one side of the pipe joint from the locking washer body, the tail ends of the internal teeth form barb-shaped tips, and the tips are tightly held outside the flow guide pipe.

Researches show that the fixing effect of the connecting device in the device is poor and the stability is not good enough.
