Regulating valve support in pipe shaped housing

摘要

The regulating valve shaft (2) holds the regulating valve (1) in a casing (6), with it's ends located in the recess (4) of the housing wall and the cross-section of the regulating valve and continuing slit (7) running through the valve. The recess in the housing wall borings with the same diameter as the bearings (5) of the regulating valve shaft in which they are arranged. The casing of the regulating valve shaft is made from synthetic material with sliding characteristics. In the recess of the housing wall, the ends of the casing extending from the rotating axis of the regulating valve shaft to the direction of the atmospheric pressure side of the regulating valve support about the radius of the recess of the said housing wall.
