【Technical field】
The present invention relates to the technical field of pipe fitting, especially a kind of technical field of ferrule-type compression joint.
【Background technology】
The installation operation that ferrule-type compression joint is attached pipeline is very convenient, currently, supplying system in natural gas used for automobile
In system, the connection type of fuel conduit is usually attached with bite type connection type, but generated at runtime due to vehicle
It vibrates, very big etc. the reasons of temperature change of pipeline surface quality and liquefied natural gas line, easily causes the close of pipeline
The leakproofness that envelope property declines and causes fuel to leak, therefore pipe joint is effectively ensured is that natural gas vehicle feed system safely may be used
By the key of operation.
Ferrule-type compression joint usually requires that the accurate seamless pipe using regulation hardness as by connecting leg, connection feature be according to
Pipeline tube wall, which is tightly bitten, by the cutting edge port of cutting ferrule so that managing interior high-pressure fluid is sealed；In addition, relative to welding type pipe
For connector, ferrule-type compression joint, which will not generate oxide skin during the installation process, causes pipeline to pollute, therefore ferrule-type compression joint is wide
The general common pipe-line system suitable for pipe with small pipe diameter high-low pressure.
Common single hoop bite type structure in connecting leg fastener cycle, is not had the unexpected change of power in connection for operator
Change, operator is imperceptible to tighten operation " end ", therefore operator will not perceive and complete to be fastenedly connected, and be frequently not
" excessively stubborn " is exactly " owing to twist ", and for cutting ferrule cutting more more recessed deeper by connecting leg faying face, the tightness of connection is better, but cuts too deep
It easily causes to be declined by connecting leg bearing capacity；In addition, during cutting ferrule tensioning is pushed forward, the power acted on nut is all transmitted
To cutting ferrule, when nut is more than fittings body and the resistance rotated to cutting ferrule by connecting leg to the driving force that cutting ferrule rotates, cutting ferrule meeting
Cause to scratch or destroy sealed faying face with nut rotation, causes fuel leakage accident.
