Abstract

The invention relates to a main steam regulation combined steam valve for a steam turbine, which comprises a valve shell part, the valve shell part comprises a valve body and a diffusion steam nozzle, the valve body is internally provided with a valve cavity, a steam inlet and a steam outlet are formed in the valve body, and the diffusion steam nozzle is arranged in the valve cavity; the valve element part comprises an adjusting valve element assembly and a main steam valve element assembly, the adjusting valve element assembly comprises an adjusting valve sleeve, an adjusting valve rod and an adjusting valve disc, the main steam valve element assembly comprises a main steam valve rod and a main steam valve disc, the adjusting valve sleeve is vertically fixed above the diffusion steam nozzle, the adjusting valve disc is slidably installed on the adjusting valve sleeve, and the main steam valve disc is slidably installed on the main steam valve rod. The lower end of the adjusting valve rod is used for driving the adjusting valve disc to vertically slide; an adjusting cavity is formed in the lower end of the adjusting valve disc, the main steam valve disc is installed in the adjusting cavity in a sliding mode, and the upper end of the main steam valve rod is used for driving the main steam valve disc to vertically slide. During use, a lever connecting rod mechanism is omitted, so that the structure of a steam turbine adjusting system is greatly simplified, the size of a steam turbine body is reduced, and comprehensive management of steam inlet shutoff and steam inlet flow adjustment is achieved.

Description

technical field [0001] The invention relates to the technical field of steam inlet shutoff and inlet steam flow regulation of a steam turbine, in particular to a combined steam valve for main steam regulation of a steam turbine. Background technique [0002] At present, there are still major problems in energy utilization, such as low utilization efficiency, poor economic benefits, and high pressure on the ecological environment. As an important content of energy development strategic planning, improving the comprehensive utilization rate of energy is in a priority position. [0003] my country is rich in industrial waste heat resources, which widely exist in the production process of all walks of life. Domestic waste heat recovery projects are in the momentum of development, and the number of steam turbines used for power generation by waste heat utilization has increased accordingly. The waste heat energy is characterized by relatively low temperature and poor thermal qual...
