Description

A flared clamp type pipe connector

technical field

The invention relates to the technical field of pipeline connection equipment, in particular to a flared clamp type pipeline connector.

Background technique

Pipe connector is a connection tool between pipes and pipes. It is a detachable connection point between pipes and pipes. It plays an indispensable and important role in pipe connection. It is one of the main components of the pipeline network. According to Different fluids in the pipeline have different requirements for pipeline connectors. For this reason, various connectors have been manufactured. For example, the existing conventional pipeline connectors have the following structures, including sealing strips, Gear ring type stainless steel ring, outer shell, locking screw, this pipe connector is equipped with a gear ring type stainless steel ring at both ends of the inner casing, and a sealing ring formed by a sealing strip rolled along the arc surface of the inner wall of the casing is placed in the middle. , When in use, insert the tubes from the two ports of the connector to the specified positions, and then tighten the locking screws. Under the pulling force of the locking screws, the connector shell is curled inward, and the toothed ring-type stainless steel ring is synchronously curled to make it The teeth bite the pipe to fix the connector on the pipe. At the same time, the sealing ring is also crimped inward, tightly hugging the outer wall of the pipe, preventing the fluid from leaking out and acting as a seal.

When using the existing pipe connector, if the hardness of the pipe is greater than the hardness of the teeth on the elastic clip, the teeth cannot firmly bite the pipe, and the pressure of the fluid between the pipes is relatively high. Large, in this way, this kind of pipe connector can easily make the pipe withdraw or disengage from the connector, so that the interface bursts open, resulting in fluid leakage. At this time, it will not only waste resources, but also cause inconvenience to people's lives. , More importantly, when the fluid is toxic, harmful, flammable or explosive, it will seriously affect people's normal life, and even endanger people's life, health and property safety. In addition, this pipeline connector is suitable for In the case where the nominal pressure of the fluid is relatively small, when the fluid pressure is slightly larger, the toothed ring type stainless steel ring will open in the direction of the pipe, and the pipe will come out, causing the fluid to leak out.
