Description
Technical field
The present invention relates to pipeline connecting device technical field, specially a kind of flaring hoop type pipeline connector.
Background technique
Pipe jointer is the fastening means between pipeline and pipeline, is the tie point that can be dismounted between pipe and pipe,
Indispensable key player is acted as in pipeline connection, it is one of piping network main composition part, according to flowing in pipeline
The difference of body, the requirement to pipe jointer is also just different, for this purpose, people are manufactured that various connectors, for example,
Existing conventional pipe jointer, structure is as follows, including sealing strip, ring gear type stainless steel coil, outer housing, lock screw, this
Pipe jointer respectively placed ring gear type stainless steel coil at its interior of shell both ends, and centre is placed with by sealing strip along inner walls arc
Shape roll at sealing ring then tighten lock spiral shell in use, pipe is inserted into specified position from connector two-port respectively
Silk, under tightly lock screw pulling force effect, connector shell is inwardly crispaturaed, and compressing ring gear type stainless steel coil, which synchronizes to crispatura, makes its teeth
Pipe is bitten, connector is fixed on pipe with this, sealing ring is also inwardly crispaturaed at the same time, tightly embraces pipe outer wall, is hindered
Only fluid leakage seals.
When using existing this pipe jointer, if the hardness of pipe is greater than the hardness of the teeth on elastic clipping strip, tooth
Tooth also just can not firmly bite pipe, and due to the pressure of the fluid between pipeline and pipeline be it is bigger, so
This pipe jointer is easy for so that pipe is exited or disengaged from connector, so that interface pops, causes fluid
Leak, at this time not only can waste of resource, bring inconvenience to people's lives, it is often more important that, when fluid be it is toxic, harmful,
When inflammable or explosive fluid, the normal life of people can be seriously affected, or even endangers the life and health and property peace of people
Entirely, in addition to this, this pipe jointer is suitable for the smaller occasion of fluid nominal pressure, when Fluid pressure is slightly larger, ring gear
Type stainless steel coil can be opened to de- pipe direction, and pipe can be deviate from, and fluid leakage is caused.
Summary of the invention
