Importance of cooperation of universities with machine-building enterprises from the point of view of an intensification of creation of objects of intellectual property is shown in article. The description of the valve design developed by authors for the main pipeline which allows to provide compensation of excessive pressure in an internal cavity when finding a lock in a closed position and heating of the case of a valve is given. The described design of a valve can be used as shutoff valves on pipelines of nuclear power plants, thermal power plants, main oil and gas pipelines.
Keywords: valve, main pipeline, pipeline fittings, pipeline transport.
