CONSTRUCTION UNIT head spindle into the valve

摘要

The invention relates to mechanical engineering, namely to the armature, in particular for the construction of the spindle head assembly in the valves and can be used not only in various types of valves, such as V-belts and slide, but in the pipe fittings of the valve group.; The technical problem to be solved is to provide a useful model spindle head assembly designs in valves free from the drawbacks mentioned above.; The problem is solved in that the spindle head assembly design in valves having a circular head at the spindle cooperating with a hole in the wedge (vanes), and the spindle head has a helical surface passed through the mating screw surface of the blind hole in the wedge (gate) and placed in a cylindrical recess the latter, whose height is greater than the height of the screw surface of the spindle head, and the screw surface length of the blind bore in the wedge is less than the length of the groove on the spindle having an internal diameter of less than nnego diameter of the screw surface.
