Problems solved by technology

Since the side of the open ring in contact with the connected pipe is a smooth surface, the connecting pipe is easy to loosen under the action of a sudden increase in the internal pressure of the pipe, pipe vibration and other external forces, resulting in the leakage of gas or liquid in the connecting pipe

Embodiment

[0014] See figure 1 and 2 . Stainless steel ring material is used, the inner surface of the ring is tapped with metric threads 1 , the outer surface of the ring is processed into a spherical shape 2 , and an opening 3 is formed by truncating the ring body perpendicular to the lower plane.

[0015] Put the lock nut with internal thread on the outside of the connected pipe, the processed split ring of the present invention is placed outside the pipe and in the lock nut, and then further install the gasket and O-shaped rubber sealing ring, the lock nut and Fitting with pipe joints with external threads, since the split ring is a spherical ring, the split ring is squeezed by rotating the lock nut, so that the opening of the split ring is gradually reduced, and the pipes are firmly connected; and because the split ring contacts The surface is metric thread, which can strengthen the locking force with the outer surface of the connected pipe and prevent the connecting pipe from loo...

Abstract

The present invention belongs to pipeline connection fitting, it particular, it relates to a snap ring with female screw for non-screw pipe connection. The described snap ring is a circular ring with opened end, the outer contact surface of said circular ring is made into the form of sphere, and its inner contact surface has meter screw. Said snap ring can be matched with locking nut with inner screw and pipe connection with outer screw. Because the inner contact surface of the snap ring has meter screw, it can raise the locking force with outer surface of connected pipe and can prevent connected pipe from being loosed.

Description

technical field [0001] The invention belongs to pipeline connection fittings, in particular to a split ring with internal threads for threadless pipe joints. Background technique [0002] The use of threadless pipes for pipeline installation is a new technology for pipeline installation in the modern world, and it is also being promoted in our country. Compared with the installation of threaded pipelines, it has the advantages of quick installation, good sealing performance, no need for special thread processing equipment on site, and reusability. Two pipes can be connected without tapping, welding and reaming. The tubes are connected. The threadless pipe joint is one of the important parts to connect the threadless pipe, and the split ring is the key part of the threadless pipe joint. Its structural design and quality directly affect the installation effect of the pipeline. And the split ring used at present is a circular ring with an opening. When installing, the pipelin...
