Working Principle of Double Ferrule Tube Fitting
Working Principle of Double Ferrule Tube Fitting
The double ferrule tube fitting is a mechanical device used to seal and tighten the conduit material. The mechanical advantages and geometry of the joint make the mechanism a leak proof seal assembly.
When assembling the joint assembly, just insert the pipe into a complete set of assembly. When the pipe reaches the bottom, it can contact the shoulder of the compression fitting body. When the ferrule nut is rotated clockwise, the mechanical thrust generated pushes the two ferrules of the joint assembly forward between the ferrule nut and the joint body. The mechanical thrust pushes the rear ferrule (3) against the conical back of the front ferrule (2), and at the same time, the thrust pushes the front ferrule into the conical taper of the joint body. At this time, the front ferrule is pulled out and a whole face seal is formed on the tapered surface of the joint body. When you feel that it has been tightened by hand, turn the ferrule nut 1-1 / 4 turn from the manual tightening position to ensure that the thrust on the seal is uniform. In this way, the effective sealing effect can be obtained in the environment of high pressure and ultra-high straight air.
