The thread rotary orientation of flange connecting hole in second flange section among screw rod on the contrary, set screw rod collar nut, by selecting spiral shell
Knock-off joint nut can fasten two ring flanges, install convenient.
Scheme 7：According to the assembling pipe joint described in scheme any one of 1-4, the pipeline connecting hole and flange connecting hole
On same circumference.
Scheme 8：According to the assembling pipe joint described in scheme any one of 1-4, the lip ring is rubber parts.
Scheme 9：According to the assembling pipe joint described in scheme any one of 1-4, in the first flange disk, second flange disk
Protective jacket is arranged with, protective jacket wraps up first, second extension and lip ring, adds the reliable of connector
Property.
The utility model have the advantage that for：The attachment means are by the way that lip ring is pressed to first, second
Between extension, quickly two petroleum pipelines can be docked, improve operating efficiency, and pipeline company can be improved
The sealing connect, prevents liquid in pipe from leaking.The extension docking of two ring flanges, the flange end for docking latter two ring flange lead to
Cross flange fastener to be fixed together, thicker lip ring can be used, effectively absorb oscillating load, at the same it is thicker
Lip ring also allows the interface of the petroleum pipeline of connection diametrically to have certain deviation.According to above-mentioned analysis, this practicality
New assembling pipe joint can avoid pipeline hydraulic fluid port from misplacing, and add the service life of connector.
