The invention adopts the following technical scheme to realize the purpose:

position adjustable three way connection, including pipe A and pipe B, pipe B with pipe A intercommunication constitutes the tee bend, pipe A overlaps on the pipeline, the pipeline corresponds pipe B's position is equipped with the through-hole, pipe A both ends are equipped with respectively and are used for with pipe A fastening is in lock mother and fastening screw on the pipeline, the lock mother with be equipped with the sealing washer on the pipeline between the pipe A, be equipped with the external screw thread that is used for installing the branch pipeline on the pipe B outer wall.

The tube B is perpendicular to the tube A, or the tube B and the outer wall of the tube A are obliquely arranged.

A through hole A and a through hole B are formed in the lock nut along the axial direction of the lock nut, the through hole A is matched with the outer diameter of the pipeline, and the through hole B is matched with the outer diameter of the pipe A.

And the lock nut is provided with a threaded hole for mounting the fastening screw along the radial direction of the lock nut.

And a chamfer A used for pressing the sealing ring is arranged on the inner wall of the lock nut.

And chamfers B used for pressing the sealing ring are respectively arranged on the inner sides of the two ends of the pipe A.

The outer sides of the two ends of the pipe A are respectively provided with a groove which is convenient for the locking nut to be inserted into the pipe A.

The tube A and the tube B are designed in an integrated forming mode.

By adopting the structure, the invention can bring the following beneficial effects:

through design pipe A, pipe B, lock mother and sealing washer, realize that pipe A can follow the pipeline and remove arbitrary position, on-the-spot trompil (through-hole) on the pipeline after the location, the tee bend is realized with pipe B intercommunication to the pipeline, then female through the lock, the sealing washer is with the sealed fastening of pipe A on the pipeline, pipe A in this application only plays the effect that the installation supported and need not communicate with the pipeline, same root pipeline self is just equivalent to two-way, the current tee bend design theory of subversion, moreover, the steam generator is simple in operation, high durability and convenient installation, can adjust the trompil intercommunication again according to on-the-spot actual position. The replacement of tee joint position can be realized only by disassembling branch pipes and loosening the locking nuts during later maintenance.
