The more specific technical solution of the utility model.
The rear end end face of the nozzle ontology 1 is closely connected on internal thread hole bottom surface, to reach end face seal requirement,
Avoid nozzle ontology leak adhesive.
Time interval is arranged between adjacent two external screw threads 15,16 on the screw rod 14.
The diameter all same of external screw thread 15,16 on 14 lateral wall of the screw rod.
The internal thread hole 21 is double thread hole, and the external screw thread 15,16 on the screw rod 14 is double thread.Certainly in described
Threaded hole 21 can also be three threaded holes, and the external screw thread 15,16 on the screw rod 14 corresponds to three screw threads.

It is the principle and reason that the utility model nozzle does not allow damage below.
The nozzle ontology of the utility model and nozzle flanged joint in place after, the contact face of the two is needed by a level pressure
Clamp force flexible deformation compresses to reach end face seal requirement.In this process, this pressing force is the interior spiral shell of nozzle flange
Effective engaged section of pit gives the sum total of compression on the external screw thread of screw rod.It is assumed that flank is uniform by pressure, then spiral shell
For line closer to end face, internal stress is bigger, and corresponding flexible deformation is with regard to bigger.When pre-fastening moment is excessive, near proximal end face
It may be more than elastic deformation limit to engage deformed threads, form plastic deformation；Hereafter, often dismounting can make for the threaded connection
At flank damage, breakage or the failure torn open not open.Double end or multiple thread than common single thread screw thread stress evenly,
Also evenly, while the helical pitch of the single screw thread of thread segment of equal length is shorter for deformation quantity, thus in dismounting mating surface by
