Centering mechanism SHUTTER normally closed valve spring

摘要

Mechanism of centering the valve normally closed PRUZHRSHNOGO VALVE; The invention relates to the art of mechanical engineering, and more particularly, to a valve agregatostroeniyu and may be used in cryogenic pnevmogidrosistemah with termotsiklmirovaniem structures from cryogenic temperatures to above-zero order ZZZK, as well as in conventional air systems, with considerable throttling of the working media through the valve-saddle pair, causing cooling down of its elements, followed by freezing out in the interfaces of moisture contained in the pumped working medium flow.; Centering mechanism shutter normally closed spring valve consisting of kinematically connected to the gate of the movable element is centered in the housing relative to the fixed seat, wherein the movable member is made of Metal-isolator, which is arranged coaxially with the gate inside the spring, and one of the reference terminals isolator is rigidly connected to the gate , the other with a housing in which is formed a stop limiting the size of the working stroke when opening the gate, in can be a movable member be used n the set of series-connected Metal-isolators.
